Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.Startle Reaction: A complex involuntary response to an unexpected strong stimulus usually auditory in nature.Levodopa: The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.Antiparkinson Agents: Agents used in the treatment of Parkinson's disease. The most commonly used drugs act on the dopaminergic system in the striatum and basal ganglia or are centrally acting muscarinic antagonists.Dopamine: One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement.

The limbs tend to remain in whatever position they are placed (waxy flexibility). Catalepsy may be associated with PSYCHOTIC DISORDERS (e.g., SCHIZOPHRENIA, CATATONIC), nervous system drug toxicity, and other conditions.Tranquilizing Agents: A traditional grouping of drugs said to have a soothing or calming effect on mood, thought, or behavior. Included here are the ANTI-ANXIETY AGENTS (minor tranquilizers), ANTIMANIC AGENTS, and the ANTIPSYCHOTIC AGENTS (major tranquilizers). These drugs act by different mechanisms and are used for different therapeutic purposes.Carbidopa: An inhibitor of DOPA DECARBOXYLASE, preventing conversion of LEVODOPA to dopamine. It is used in PARKINSON DISEASE to reduce peripheral adverse effects of LEVODOPA. It has no antiparkinson actions by itself.Sensory Gating: The ability of the BRAIN to suppress neuronal responses to external sensory inputs, such as auditory and visual stimuli. Sensory filtering (or gating) allows humans to block out irrelevant, meaningless, or redundant stimuli.Hydroxydopamines: Dopamines with a hydroxy group substituted in one or more positions.Yawning: An involuntary deep INHALATION with the MOUTH open, often accompanied by the act of stretching.Quinpirole: A dopamine D2/D3 receptor agonist.Parkinson Disease: A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

Examples include parkinsonism caused by vascular injury, drugs, trauma, toxin exposure, neoplasms, infections and degenerative or hereditary conditions. Clinical features may include bradykinesia, rigidity, parkinsonian gait, and masked facies. In general, tremor is less prominent in secondary parkinsonism than in the primary form. (From Joynt, Clinical Neurology, 1998, Ch38, pp39-42)Domperidone: A specific blocker of dopamine receptors. It speeds gastrointestinal peristalsis, causes prolactin release, and is used as antiemetic and tool in the study of dopaminergic mechanisms.2,3,4,5-Tetrahydro-7,8-dihydroxy-1-phenyl-1H-3-benzazepine: A selective D1 dopamine receptor agonist used primarily as a research tool.Receptors, Dopamine D1: A subfamily of G-PROTEIN-COUPLED RECEPTORS that bind the neurotransmitter DOPAMINE and modulate its effects.

The d-form is DEXTROAMPHETAMINE.Motor Activity: The physical activity of a human or an animal as a behavioral phenomenon.Harmine: Alkaloid isolated from seeds of Peganum harmala L., Zygophyllaceae. It is identical to banisterine, or telepathine, from Banisteria caapi and is one of the active ingredients of hallucinogenic drinks made in the western Amazon region from related plants. It has no therapeutic use, but (as banisterine) was hailed as a cure for postencephalitic Parkinson disease in the 1920's.Substantia Nigra: The black substance in the ventral midbrain or the nucleus of cells containing the black substance. These cells produce DOPAMINE, an important neurotransmitter in regulation of the sensorimotor system and mood.

Modifications of local cerebral metabolic rates for glucose and motor behavior in rats with unilateral lesion of the subthalamic nucleus. (1/551)

Inactivation of the subthalamic nucleus (STN) has attracted interest as a therapeutic tool in Parkinson's disease. The functional consequences of the inactivation, however, are uncertain. In this study definition of the pattern of changes of cerebral functional activity associated with lesion of the STN and dopaminergic stimulation, by using the [14C]deoxyglucose method, was sought. Six or 7 days following unilateral lesion of the STN, the animals were divided into two groups: One group (n = 10) was administered apomorphine (1 mg/kg) subcutaneously; the second group (n = 10) received saline. The [14C]deoxyglucose procedure was initiated 10 minutes following the drug or saline injection. The results show that systemic administration of apomorphine to rats with unilateral lesion of the STN causes ipsiversive rotational behavior and asymmetries of glucose utilization of defined brain areas, including the substantia nigra reticulata, globus pallidus, and entopeduncular nucleus. These nuclei are the main targets of the subthalamic excitatory projections. Lesion of the nucleus per se (without challenge with apomorphine) has no significant consequences on glucose utilization. The findings indicate that the STN is involved in the activation of the basal ganglia output nuclei induced by systemic dopaminergic stimulation.  (+info)

Effects of tetrahydroprotoberberines on dopamine D2 receptors in ventral tegmental area of rat. (2/551)

AIM: To compare the actions of tetrahydroprotoberberines (THPB) on dopamine (DA) D2 receptors in the ventral tegmental area (VTA) of rat. METHODS: Extracellular single unit recording technique was used in i.v. gallamine-paralyzed rats. RESULTS: Eleven THPB analogs tested completely attenuated the apomorphine (Apo, 20 micrograms.kg-1)-induced inhibition on VTA DA cell firing activity. The OH group on C2 at THPB was linked with the reversal of Apo-induced inhibition. Their reversal potencies (ED50, microgram.kg-1) for D2 receptors were: THPB-143 (5.6) > SPD (8.5) > Iso (17.0) > THP (33) > THB (48) > THPB-18 (66) > THPB-1 (179) > THPB-19 (408) > THPB-126 (510) > THPB-104 (1019) > THPB-10 (4815). CONCLUSION: Among these 11 THPB, the 2-hydroxyl-THPB (THPB-143) showed the strongest antagonistic action on D2 receptors.  (+info)

Comparison of effects of haloperidol administration on amphetamine-stimulated dopamine release in the rat medial prefrontal cortex and dorsal striatum. (3/551)

Research has shown that there are important neurochemical differences between the mesocortical and mesostriatal dopamine systems. The work reported in this paper has sought to compare the regulation of dopamine release in the medial prefrontal cortex and the anterior caudate-putamen. In vivo microdialysis was used to recover dialysate fluid for subsequent assay for dopamine concentrations. The responses to D2 antagonist (haloperidol) administration, which has been shown to increase impulse-dependent dopamine release, were compared. Results demonstrated a diminished effect of systemic haloperidol administration on dopamine efflux in the prefrontal cortex. The responses to systemic administration of a nonimpulse-dependent, transporter-mediated, dopamine releaser (d-amphetamine) were also contrasted. Results again demonstrated a diminished pharmacological effect in the cortex. The potential interaction of stimulation of these two types of dopamine release was examined by coadministration of these compounds. Haloperidol pretreatment dramatically potentiated the dopamine-releasing effect of amphetamine administration. This effect was observed in both the cortex and the striatum. Subsequent work demonstrated that this effect of haloperidol was mediated by D2-like receptors in the prefrontal cortex. These results are discussed in relation to other neurochemical and neuroanatomical studies demonstrating sparse densities of dopamine transporter sites and dopamine D2 receptors in the cortex compared with the striatum. They demonstrate a functional correlate to the recently reported, largely extrasynaptic localization of dopamine transporter sites in the prefrontal cortex. Furthermore, they demonstrate the existence of cortical D2-like autoreceptors that may normally be "silent" under basal conditions.  (+info)

Multisecond oscillations in firing rate in the basal ganglia: robust modulation by dopamine receptor activation and anesthesia. (4/551)

Multisecond oscillations in firing rate in the basal ganglia: robust modulation by dopamine receptor activation and anesthesia. Studies of CNS electrophysiology have suggested an important role for oscillatory neuronal activity in sensory perception, sensorimotor integration, and movement timing. In extracellular single-unit recording studies in awake, immobilized rats, we have found that many tonically active neurons in the entopeduncular nucleus (n = 15), globus pallidus (n = 31), and substantia nigra pars reticulata (n = 31) have slow oscillations in firing rate in the seconds-to-minutes range. Basal oscillation amplitude ranged up to +/-50% of the mean firing rate. Spectral analysis was performed on spike trains to determine whether these multisecond oscillations were significantly periodic. Significant activity in power spectra (in the 2- to 60-s range of periods) from basal spike trains was found for 56% of neurons in these three nuclei. Spectral peaks corresponded to oscillations with mean periods of approximately 30 s in each nucleus. Multisecond baseline oscillations were also found in 21% of substantia nigra dopaminergic neurons. The dopamine agonist apomorphine (0.32 mg/kg iv, n = 10-15) profoundly affected multisecond oscillations, increasing oscillatory frequency (means of spectral peak periods were reduced to approximately 15 s) and increasing the regularity of the oscillations. Apomorphine effects on oscillations in firing rate were more consistent from unit to unit than were its effects on mean firing rates in the entopeduncular nucleus and substantia nigra. Apomorphine modulation of multisecond periodic oscillations was reversed by either D1 or D2 antagonists and was mimicked by the combination of selective D1 (SKF 81297) and D2 (quinpirole) agonists. Seventeen percent of neurons had additional baseline periodic activity in a faster range (0.4-2.0 s) related to ventilation. Multisecond periodicities were rarely found in neurons in anesthetized rats (n = 29), suggesting that this phenomenon is sensitive to overall reductions in central activity. The data demonstrate significant structure in basal ganglia neuron spiking activity at unexpectedly long time scales, as well as a novel effect of dopamine on firing pattern in this slow temporal domain. The modulation of multisecond periodicities in firing rate by dopaminergic agonists suggests the involvement of these patterns in behaviors and cognitive processes that are affected by dopamine. Periodic firing rate oscillations in basal ganglia output nuclei should strongly affect the firing patterns of target neurons and are likely involved in coordinating neural activity responsible for motor sequences. Modulation of slow, periodic oscillations in firing rate may be an important mechanism by which dopamine influences motor and cognitive processes in normal and dysfunctional states.  (+info)

Disruption of latent inhibition in rats with postnatal hippocampal lesions. (5/551)

Disruption of latent inhibition has been proposed as a possible model of cognitive abnormalities that underlie positive symptoms of a schizophrenia. We tested neonatal hippocampal lesioned rats in a latent inhibition paradigm. Lesions of the ventral hippocampus were induced by bilateral injections of ibotenic acid in 7 days old rats. The behavior of lesioned rats was tested postpubertally. We found a hyperresponsiveness to dopaminergic stimulation by apomorphine in locomotion tests. Latent inhibition was tested using the acquisition of a conditioned reaction in a two-way shuttle box. Sham operated control animals showed after preexposure of the to-be-conditioned stimulus (combined tone and light stimulus) a low acquisition. Ibotenic acid lesioned animals learned the conditioned reaction with and without preexposure in the same way, indicating disturbed latent inhibition. These results demonstrate disturbances in early postnatal hippocampal lesioned rats comparable with those seen in schizophrenic patients, thus further validating this procedure as a useful animal model of some aspects of schizophrenia.  (+info)

Rat strain differences in the ability to disrupt sensorimotor gating are limited to the dopaminergic system, specific to prepulse inhibition, and unrelated to changes in startle amplitude or nucleus accumbens dopamine receptor sensitivity. (6/551)

Previous studies indicate that a variety of pharmacological agents interfere with the prepulse inhibition of the acoustic startle (PPI) response including phencyclidine (PCP), 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT), amphetamine, and apomorphine. Strain differences have been observed in the ability of apomorphine to disrupt PPI, although the degree to which these strain differences occur after administration of nondopaminergic drugs or the degree to which differences can be observed in other models of dopamine (DA) receptor activation has not been elucidated. The present study tested the effects of apomorphine, amphetamine, 8-OH-DPAT, and PCP on PPI in the Sprague Dawley and Wistar rat strains. Because apomorphine disrupts PPI via activation of DA receptors in the nucleus accumbens, apomorphine-induced hyperlocomotion, also a behavioral model of nucleus accumbens DA receptor activation, was measured in both rat strains. Administration of PCP or 8-OH-DPAT attenuated PPI in both strains, whereas apomorphine and amphetamine only attenuated PPI in Wistar rats. The ability of apomorphine to increase motor activity in the absence of a startle-eliciting stimulus was similar in the two strains, as was apomorphine-induced hyperlocomotion. A time course analysis of the effects of apomorphine on startle response in Sprague Dawley rats found that changes in the magnitude of PPI followed changes in basic startle amplitude. Similarly, no apomorphine-induced attenuation of PPI was observed in Sprague Dawley rats after 6-OHDA-induced DA receptor supersensitivity in the nucleus accumbens. These data suggest a dissociation between the effects of DA receptor agonists in PPI and other behavioral models of DA receptor activation.  (+info)

Effects of sustained phencyclidine exposure on sensorimotor gating of startle in rats. (7/551)

Phencyclidine (PCP), a non-competitive NMDA antagonist with actions at multiple other central nervous system receptors, can cause both acute and lasting psychoses in humans, and has also been used in cross-species models of psychosis. Acute exposure to PCP in rats produces behavioral changes, including a loss of prepulse inhibition (PPI) of the startle reflex, which parallels the loss of PPI observed in schizophrenia patients. Sustained exposure to PCP in rats produces neuropathological changes in several limbic regions and prolonged behavioral abnormalities that may parallel neuropsychological deficits in schizophrenia. It is unclear whether sustained PCP exposure will also produce a loss of prepulse inhibition which parallels the decrease observed in schizophrenia patients. In the present study, we examined changes in PPI during and after sustained PCP administration, using 5-day PCP exposure via subcutaneous osmotic minipumps, or 14-day PCP exposure via repeated intraperitoneal injections. In both forms of drug delivery, PPI was disrupted during, but not after, sustained drug exposure. PPI does not appear to be sensitive to neuropathological effects of sustained PCP exposure.  (+info)

Altered activity of midbrain dopamine neurons following 7-day withdrawal from chronic cocaine abuse is normalized by D2 receptor stimulation during the early withdrawal phase. (8/551)

Using in vivo single-unit recording in rats, we compared the effects of continuous cocaine infusion via minipump or single daily injections (both 40 mg/kg/d x 14 days, S.C.) on the activity of putative dopamine (DA) neurons in the substantia nigra pars compacta (SNC) and ventral tegmental area (VTA). On days 1-5 after cocaine withdrawal, animals were further treated with single daily injections of DA agonists. On withdrawal day 7 continuous cocaine caused a reduction in spontaneously active neurons in the SNC and reduced bursting in the VTA. In contrast, intermittent cocaine resulted in an increase in the number of active neurons in the VTA. These changes were all reversed by apomorphine or quinpirole given during the first 5 withdrawal days. The D1 antagonist SCH 39166 did not antagonize the effects of apomorphine in either region. The role of D2 receptors in modulating baseline DA activity during intermediate cocaine withdrawal is discussed.  (+info)

In addition to their well characterized effects at dopamine receptors, neuroleptic drugs have been shown to affect the level and in vitro metabolism of neuropeptides. In the present study, the effect of acute and subchronic administration of the neuroleptic haloperidol and the nonselective, dopamine agonist apomorphine on neuropeptidase activity was determined in regional, rat brain P2 membranes. Subchronic administration of haloperidol decreased the activity of aminopeptidase N in the frontal cortex and caudate-putamen. In contrast, subchronic administration of apomorphine increased aminopeptidase N activity in the frontal cortex and caudate-putamen. Neutral endopeptidase 24.11 also was affected differentially in the caudate-putamen, but both subchronic haloperidol and apomorphine decreased neutral endopeptidase 24.11 activity in the frontal cortex. Metalloendopeptidase 24.15 activity was decreased in the caudate-putamen after acute haloperidol and increased in the frontal cortex after acute ...

The effects of 7-(4-[4-(2,3-dichlorophenyl)-1-piperazinyl]butyloxy)-3,4-dihydro-2 (1H)- quinolinone (OPC-14597), a derivative of the dopamine (DA) autoreceptor agonist 7-(3-[4-(2,3-dimethylphenyl)piperazinyl]propoxy)-2(1H)-quinolinone (OPC-4392), on DA receptors were biochemically and behaviorally studied and compared with those of OPC-4392. Both OPC-14597 and OPC-4392 inhibited reserpine- and gamma-butyrolactone (GBL)-induced increase in tyrosine hydroxylase activity in the mouse and rat brain. The effects of OPC-14597 were comparable to those of OPC-4392 and were completely antagonized by haloperidol. OPC-14597, unlike apomorphine, did not evoke postsynaptic DA receptor-stimulating behavioral signs such as hyperlocomotion in the reserpinized mice and contralateral rotation in rats with unilateral striatal 6-hydroxydopamine lesions. Both OPC-14597 and OPC-4392 inhibited such apomorphine-induced postsynaptic behavioral changes as stereotypy and hyperlocomotion in mice and rats and rotation in ...

R)-Apomorphine (1) has the potential to reduce the accumulation of amyloid β-protein (Aβ42), a causative agent of Alzheimers disease (AD). Although the inhibition of Aβ42 aggregation by 1 is ascribable to the antioxidative effect of its phenol moiety, its inhibitory mechanism at the molecular level remains to be fully elucidated. LC-MS and UV analyses revealed that 1 is autoxidized during incubation to produce an unstable o-quinone form (2), which formed a Michael adduct with Lys 16 and 28 of Aβ42. A further autoxidized form of 1 (3) with o-quinone and phenanthrene moieties suppressed Aβ42 aggregation comparable to 1, whereas treating 1 with a reductant, tris(2-carboxyethyl)phosphine diminished its inhibitory activity ...
Susan is putting herself through this drastic operation for a very modest reason: she wants her old life back. Her symptoms have been controlled in recent years with a drug called apomorphine, involving the insertion every morning of a needle into her stomach controlled by a pump, which is cumbersome and often lets her down.. She is to receive two electrode implants deep in her brain, to be attached to wires that will run under her skin to a miniature battery-operated pulse generator that will be sewn into her chest. The electrodes will permanently stimulate cells deep in her brain to alleviate her symptoms. Amazingly, she will remain awake throughout the procedure: the best indication that things have not gone to plan - a haemorrhage, for…. ...

After training under a fixed-interval 60 sec schedule of food presentation in the presence of a water tube (to permit schedule-induced licking), groups of rats received either 6-hydroxy-dopamine (6-OHDA)(8 micrograms base/2 microliters) or 0.2% ascorbate-0.9% saline vehicle bilaterally into the nucleus accumbens. 6-OHDA produced greater than 80% depletion of the catecholamines dopamine and norepinephrine and the dopamine metabolite dihydroxyphenylacetic acid in the nucleus accumbens and olfactory tubercle, but nonsignificant depletions in the corpus striatum. The behavior of the groups treated with 6-OHDA ("lesion") and vehicle ("sham") was assessed for up to 58 days postoperatively. In the first few days after 6-OHDA, the lesion group showed reductions in high rates of responding toward the end and in high rates of licking at the beginning of the fixed-interval. However, licking was increased during later portions of the fixed interval in the lesion group. d-Amphetamine (0.25-2.0 mg/kg) ...

During apo blebs, containing nuclear components, are formed at the cells surfaces. When these blebs separate from the dying cell an apo cell body remains. The contents of apo blebs are modified and can be released, especially in patients with systemic lupus erythematosus (SLE) since impaired clearance of apo material has been observed in this autoimmune condition. Accordingly, autoantibodies present in subjects with SLE bind to apo blebs. Based on AnxA5 binding, and permeability for PI, we show that apo blebs can be categorized as early (AnxA5(+)/PI(- )) or late (AnxA5(+)/PI(+)) apo ones. Both forms of blebs contain apo-induced chromatin modifications and are efficiently phagocytosed by dendritic cell (DC). Uptake by DC of late, but also early apo blebs, stimulate DC to produce IL-6. This bleb-induced effect on DC may be an important step in the initiation of the autoimmune responses in SLE ...

en] The identification of the brain structures and neurotransmitters responsible for the generation and/or modulation of the mismatch negativity (MMN) may contribute to a clearer understanding of its functional significance, and may have clinical implications. In this context, some findings suggest that the scalp-recorded MMN reflects activity from multiple neuronal ensembles within or in the immediate vicinity of the primary auditory cortex and with possible contribution from the frontal cortex. However, few data are available concerning the influence of neurotransmitter systems on the MMN. In this study, the relationship between both noradrenergic and dopaminergic systems and the MMN were investigated in 34 healthy volunteers. Noradrenergic and dopaminergic activities were assessed with the apomorphine and clonidine challenge tests. The results showed no significant relationship between either growth hormone (GH) responses to apomorphine or clonidine and the MMN amplitude or latency. ...

Cogent evidence points to the involvement of neurosteroids in the regulation of dopamine (DA) neurotransmission and signaling, yet the neurobiological bases of this link remain poorly understood. We previously showed that inhibition of 5α-reductase (5αR), a key neurosteroidogenic enzyme, attenuates the sensorimotor gating deficits induced by DA receptor activation, as measured by the prepulse inhibition (PPI) of the acoustic startle reflex. To extend these findings, the present study was aimed at the assessment of the role of other key neurosteroidogenic enzymes in PPI, such as 17α-hydroxylase/C17,20 lyase (CYP17A1), 3α- and 3β-hydroxysteroid dehydrogenase (HSD), in Sprague-Dawley rats. The PPI deficits induced by the DAergic non-selective agonist apomorphine (APO, 0.25 mg/kg, SC) were dose-dependently attenuated by the selective CYP17A1 inhibitor abiraterone (ABI, 10-50 mg/kg, IP) in a fashion akin to that of the 5αR inhibitor finasteride (FIN, 100 mg/kg, IP). These systemic effects were ...
Several studies have suggested a role of BDNF in the development of schizophrenia. For example, post-mortem studies have shown significantly reduced levels of BDNF protein expression in the brain of schizophrenia patients. We investigated the relationship between reduced levels of BDNF in the brain and the regulation of prepulse inhibition (PPI), a behavioral endophenotype of schizophrenia. We used BDNF heterozygous mutant rats which display a 50% decrease of mature BDNF protein levels. Previously, we observed normal baseline PPI and responses to the dopamine D1/D2 receptor agonist, apomorphine, in these rats. Here, we focused on the effects of the NMDA receptor antagonist, MK-801, its interaction with mGluR2/3 and mGluR5 receptors, and the PPI response to serotonergic drugs. MK-801 administration caused a dose-dependent reduction of PPI and increase of startle amplitudes. Baseline PPI and the effect of 0.02-0.1mg/kg of MK-801 were not significantly altered in male or female BDNF heterozygous rats,

On the horizon is sublingual apomorphine, effective in 40 minutes, and with fewer interactions than sildenafil.. There was an entertaining debate of the motion "This house believes that education and counselling cannot produce significant and lasting changes in sexual behaviour." Dr Oliver Davidson speaking against the motion persuaded the house to change from 72 for and 77 against to 55 for and 92 against, after the debate.. A McOwan and colleagues presented the result of their postal survey of four central London primary care groups. Of the 120 replies received (51% response rate), 85% categorised themselves as currently offering level 1 service in the sexual health strategy. Only 11% wish to offer level 2 service for the future. Interestingly, only 2% of these general practitioners surveyed would currently look to another general ...

Antifreeze (ethylene glycol), as a result of its sweet flavor, poses an Extraordinary Threat of poisoning to dogs and cats if ingested. Even an exceedingly small sum like a tablespoon can certainly show deadly. The antifreeze alone is not toxic, but is metabolized by means of the liver to the toxins glycolate and oxalate, which cause intoxication and vomiting, metabolic acidosis, and finally acute kidney failure resulting in seizures and Demise. By the time clinical signs are noticed, the kidneys are often way too weakened for the Doggy to survive so acting quickly is vital.

As of 2014[update], the safety and efficacy of more than 400 pharmaceutical treatments had been or were being investigated in over 1,500 clinical trials worldwide, and approximately a quarter of these compounds are in Phase III trials, the last step prior to review by regulatory agencies.[250] On the other hand, in the decade 2002-2012, 244 compounds were assessed in Phase I, Phase II, or Phase III trials, and only one of these (memantine) received FDA approval (though others were still in the pipeline).[251]. One area of clinical research is focused on treating the underlying disease pathology. Reduction of beta-amyloid levels is a common target of compounds[252] (such as apomorphine) under investigation. Immunotherapy or vaccination for the amyloid protein is one treatment modality under study.[253] Unlike preventative vaccination, the putative therapy would be used to treat people already diagnosed. It is based upon the concept of training the immune system to recognise, attack, and reverse ...

This case series confirms the findings of previous reports that bilateral STN DBS is an effective treatment for patients with advanced Parkinsons disease.5-,9 Significant improvements were seen in all parkinsonian symptoms. In patients previously reliant on apomorphine infusion, this surgical intervention enabled four of six patients either to dispense with apomorphine or to switch from an infusion to a lower dose given as intermittent subcutaneous injections. This has resulted in a great improvement in the patients and carers quality of life. Longer follow up of these patients is required to determine if this initial improvement at six months is maintained.. The practice at our centre of using apomorphine infusion as a treatment for motor fluctuations is such that the patients presented here were at a more advanced stage compared with other previously reported groups. Thus the mean (SD) UPDRS part III (motor score) preoperatively off medication was in general higher in our series at 74.3 ...

TY - JOUR. T1 - Galantamine and donepezil attenuate pharmacologically induced deficits in prepulse inhibition in rats. AU - Hohnadel, Elizabeth. AU - Bouchard, Kristy. AU - Terry, Alvin V. PY - 2007/2/1. Y1 - 2007/2/1. N2 - Acetylcholinesterase inhibitors (AChEIs) are currently being evaluated as adjunctive therapy for the cognitive dysfunction of schizophrenia. This core symptom of schizophrenia has often been attributed to impaired attention and abnormal sensory motor gating, features that are also found in Huntingtons Disease, autism, and several other psychiatric and neurological disorders. The ability to improve prepulse inhibition (PPI) of the acoustic startle response may predict the efficacy of compounds as cognitive enhancers. In this study, PPI was disrupted in Wistar rats in three pharmacologic models: dopamine receptor agonism by apomorphine, NMDA receptor antagonism by MK801, or muscarinic acetylcholine receptor antagonism by scopolamine. We then evaluated the commonly used AChEIs, ...

TY - JOUR. T1 - Effects of central dopamine depletion on the d-amphetamine discriminative stimulus in rats. AU - Woolverton, William L.. AU - Cervo, Luigi. PY - 1986/6. Y1 - 1986/6. N2 - The discriminative stimulus properties of d-amphetamine, cocaine, and apomorphine were assessed in rats trained in a two-lever, food-reinforced drug discrimination paradigm to discriminate 1.0 mg/kg d-amphetamine from saline. After determination of these dose-response relationships, the rats were divided into two groups. One group (6-OHDA) was given injections of desmethylimipramine (DMI, 30 mg/kg, IP) and 6-hydroxydopamine (6-OHDA, 100 μg/10 μl each ventricle), while the other group (sham) was given the same dose of DMI and 6-OHDA vehicle (intraventricularly). Beginning approximately 45 days after intraventricular injections, dose-response relationships were redetermined for all three drugs. Larger doses of d-amphetamine were required to elicit the same response in the 6-OHDA group (i.e. the dose-response ...
Data are recorded from visits most closely aligned with the planned periods of Visit 0 (V0): Baseline (After decision to use the temporary naso-duodenal tube (approximately 2-14 days) and after signature of the Patient Authorization/Informed Consent Form); Visit 1 (V1): At discharge from hospital; Visit 2 (V2): 3 months after discharge; Visit 3 (V3): 6 months after discharge; Visit 4 (V4): 12 months after discharge.. All participants have a temporary naso-duodenal tube used initially with the infusion pump to determine if the participant responds favorably to this method of treatment and to optimize the dose of Duodopa before permanent treatment is started.. Participants who choose a treatment other than Duodopa after the temporary naso-duodenal test phase are considered for the Standard of Care group. Participants who go on to select Apomorphine pump or Deep Brain Stimulation at any stage are not eligible to continue in this group or to continue in the observational period of ...
The organization of the central neuronal circuitry that produces vomiting was explored by mapping the distribution of c-fos protein (Fos)-like immunoreactivity (FLI) as a monitor of functional activity. The brainstem and spinal cord were examined in cats administered multiple emetic drugs (cisplatin, lobeline, protoveratrine, naloxone, apomorphine) or control saline injections. Some animals were decerebrated, paralyzed, and artificially ventilated to avoid possible Fos expression induced by sensory feedback or fluid depletion during vomiting. Fictive vomiting was identified in these animals by a characteristic pattern of respiratory muscle nerve (phrenic and abdominal) coactivation. Tissues were immunoprocessed using an antibody raised against amino acids 1-131 of Fos and the avidin-biotin peroxidase complex method. Enhanced nuclear FLI was observed in experimental animals along portions of the sensorimotor emetic reflex arc, including the nodose ganglia, area postrema, nuclei of the solitary ...
Could schizophrenia arise from a single gene defect?. Researchers have long puzzled over the apparently multiple causes of complex developmental disorders such as schizophrenia. Individuals seem to be predisposed to the disease by a tragic, mysterious combination of genetics, prenatal trauma, viral infection, and early experience. And its array of symptoms--including hallucinations, delusions, paranoia, and antisocial behavior--has defied simple explanation.. In experiments with rats, however, researchers led by led by Gerard J.M. Martens of the Nijmegen Center for Molecular Life Sciences (NCMLS) have demonstrated that such seemingly diverse combinations of symptoms can arise from a subtle imbalance in the activity of a single gene whose protein plays a key role in neural development.. The researchers studied the genetic differences between rats bred to be either resistant or susceptible to the drug apomorphine. A long history of studies has revealed that apomorphine-susceptible rats show many ...

The modulation of levodopa transport across the blood brain barrier by large neutral amino acids is well documented. Protein limitation and protein redistribution diets may improve motor fluctuations in patients with Parkinsons disease but the pharmacokinetics and pharmacodynamics of levodopa and amino acids are highly variable. Clinical records of 1037 Parkinsons disease patients were analyzed to determine the proportion of patients with motor fluctuations related to protein interaction with levodopa. Motor fluctuations due to protein interaction with levodopa were defined as dietary protein being associated with (i) longer time to levodopa effectiveness, (ii) reduced benefit or duration of benefit, (iii) dose failures or (iv) earlier wearing off from a previously effective dose. Dose failures, sudden, painful or behavioral wearing-off periods, gait freezing, nausea, hallucinations, orthostasis, and dyskinesias were taken as markers of motor fluctuations, disease severity, and levodopa side effects
A look at the following clinical trial: Prevalence Of Internal Pudendal Artery Disease In Patients With Erectile Dysfunction Undergoing Diagnostic Coronary Angiography.
Post-transcriptional protein synthesis by GH3 cloned pituitary cells, which secrete prolactin and growth hormone, is dependent on Ca2+. The effects of antagonists of prolactin secretion were examined on overall protein synthesis in GH3 cells as a function of cellular Ca2+ depletion and restoration at varying concentrations of extracellular Ca2+. Leucine incorporation by Ca2+-depleted cells during short incubations was reduced by 80-90%. Trifluoperazine at micromolar concentrations inhibited leucine incorporation in a Ca2+-dependent manner. The extent of inhibition varied with extracellular Ca2+ concentration and was fully reversed at higher Ca2+ concentrations. Similar patterns of inhibition of leucine incorporation were observed with nifedipine, verapamil, calmidazolium, chlorpromazine, bromocriptine, ergotamine, and the (+)- and (-)-isomers of butaclamol, but dopamine, apomorphine, and chlorpromazine sulfoxide were not inhibitory. Muscarinic agonists decreased incorporation in a Ca2+-dependent ...

Like all Martin Scorsese pictures, his newest, Shutter Island, is chiefly about sin. How it helps to define the human condition, how it affects the protagonist in life and the detrimental value it has to the eternal soul. Catholic filmmakers have varying ways of addressing sin and most pointedly guilt-but Scorseses pictures are laced with it like a poisonous substance hidden in a cinematic tonic. As he has aged, Scorseses films have become increasingly somber in tone. No longer is the rabidly gnawing theme allowed to remain a largely unspoken undercurrent beneath the characterizations and their journeys but it has emerged, front and center, as the monstrous entity meriting its own blunt manifestation. Consequently, Scorseses films have become ostensibly more garish, brassy and intentionally meretricious. Whether it be an aging Scorseses shift into the darkest underbelly of city life juxtaposed with deeply religious iconography and sacrificial angst (Bringing Out the Dead); his ...

Parkinsons disease (PD) and Alzheimers disease (AD) are neurodegenerative disorders that mainly affect the elderly population. It is believed that oxidative stress is involved in development of both these diseases and that estrogen deficiency is a risk factor for development of AD. Genistein is a plant-derived compound that is similar in structure to estrogen and has anti-oxidative properties. The general objective of the present research was to evaluate the effects of genistein on neurodegeneration in rat models of PD and AD.. Using a rat model of PD, we found that a single intraperitoneal dose of genistein 1 h before intrastriatal injection of 6-hydroxydopamine (6-OHDA) attenuated apomorphine-induced rotational behavior and protected the neurons of substantia nigra pars compacta against 6-OHDA toxicity.. To produce an animal model of AD, we injected Aβ1-40 into the hippocampus of rats. Using groups of these Aβ1-40-lesioned animals, the involvement of estrogen receptors (ERs) was evaluated ...

Using a rat model of PD, we found that a single intraperitoneal dose of genistein 1 h before intrastriatal injection of 6-hydroxydopamine (6-OHDA) attenuated apomorphine-induced rotational behavior and protected the neurons of substantia nigra pars compacta against 6-OHDA toxicity.. To produce an animal model of AD, we injected Aβ1-40 into the hippocampus of rats. Using groups of these Aβ1-40-lesioned animals, the involvement of estrogen receptors (ERs) was evaluated ...

Bromocriptine and the recently withdrawn pergolide are ergot derivatives and may rarely cause retroperitoneal, pulmonary, and pericardial fibrosis, and cardiac valvulopathies. Pramipexole and ropinirole have half-lives 6-12 hours and are therefore taken 2-3 times daily.. Pramipexole and ropinirole Pramipexole and ropinirole are not ergot compounds. Large clinical trials comparing these medications to levodopa showed that they can be used in early Parkinsons disease and reduce the severity of symptoms. Over the years, differences in the effects of the dopamine agonists have emerged. One side effect is daytime sleepiness and "sleep attacks." Although this may occur with all of the dopamine agonists (and levodopa), it was first appreciated in people treated with pramipexole.. Apomorphine Apomorphineis indicated in patients who experience "off states"refractory to modifications of oral medications such as increasing the dose or frequency of dopaminergic medications or introducting a COMT inhibitor. ...
JL13 [5-(4-methylpiperazin-1-yl)-8-chloro-pyrido[2,3-b][1,5] benzoxazepine fumarate] is a substance with a close structural resemblance to clozapine. However, it is less sensitive to oxidation and may therefore have less hematological side effects. In the present study, JL13 was compared with clozapine and haloperidol in several animal models for schizophrenia. The paw test represents a screening model for antipsychotic drugs that can discriminate between drugs with extrapyramidal side effects and drugs without. Haloperidol increased both forelimb retraction time and hindlimb retraction time (HRT), whereas both clozapine and JL13 increased only HRT. In the prepulse inhibition paradigm, all three drugs reversed the apomorphine- and the amphetamine-induced disruption of prepulse inhibition. However, whereas haloperidol was equally effective against both dopaminergic drugs, JL13 and clozapine were more effective against amphetamine. Finally, only JL13 was able to increase prepulse inhibition in ...
3H]Spiperone, a neuroleptic/dopamine receptor ligand, binds with high affinity (Kd 0.15 nM) to a single specific site on rat corpus striatum membranes. The "specific" binding represents about 80% of the total binding and is displaced by dopamime, apomorphine, and stereospecifically by neuroleptics such as butaclamol and flupenthixol. However, in contrast to the striatum, only 30-40% of the binding of [3H]spiperone to limbic forebrain membranes is displaced stereospecifically by butaclamol or flupenthixol, whereas dopamine and certain spiperone analogues compete with high affinity for about 70% of the labeled sites. These additional sites are saturable, reversible, and of high affinity. Kinetic analysis of association and dissociation rates yields a Kd value (1.5 nM) in agreement with equilibrium saturation data for these sites. They also possess a precise distribution, with high amounts being found in the hippocampus, septum, and nucleus accumbens, but they are completely absent in areas such as ...

The common, adverse drug reactions (side effects) are the same as with other PDE5 inhibitors. The frequent vardenafil-specific side-effect is nausea; the infrequent side effects are abdominal pain, back pain, photosensitivity, abnormal vision, eye pain, facial edema, hypotension, palpitation, tachycardia, arthralgia, myalgia, rash, itch, and priapism. One possibly serious, but rare, side effect with vardenafil is heart attack. Also, in rare cases, vardenafil use may cause priapism, a very painful emergency condition that can cause impotence if left untreated.[4] On 18 October 2007, the U.S. Food and Drug Administration (FDA) announced that a warning about possible deafness (sudden hearing loss) would be added to the drug labels of vardenafil, and other PDE5 inhibitors.[5] ...
The FDA's approval of sildenafil in 1998[16] was a ground-breaking commercial event for the treatment of ED, with sales exceeding US$1 billion. Subsequently, the FDA approved vardenafil in 2003,[17] and tadalafil in 2003. It initially was developed by the biotechnology company ICOS, and then again developed and marketed worldwide by Lilly ICOS, LLC, the joint venture of ICOS Corporation and Eli Lilly and Company. Tadalafil was approved in 2009 in the United States for the treatment of pulmonary arterial hypertension[18] and is under regulatory review in other regions for this condition. In late November 2008, Eli Lilly sold the exclusive rights to commercialize tadalafil for pulmonary arterial hypertension in the United States to United Therapeutics for an upfront payment of $150 million. Tadalafil was discovered by Glaxo Wellcome (now GlaxoSmithKline) under a partnership between Glaxo and ICOS to develop new drugs that began in August 1991.[19][20] In 1993, the Bothell, Washington biotechnology ...
