Central autonomic activation by intracisternal TRH analogue excites gastric splanchnic afferent neurons. (1/282)

Intracisternal (ic) injection of thyrotropin-releasing hormone (TRH) or its stable analogue RX 77368 influences gastric function via stimulation of vagal muscarinic pathways. In rats, the increase in gastric mucosal blood flow evoked by a low ic dose of RX 77368 occurs via release of calcitonin gene-related peptide from capsaicin-sensitive afferent neurons, most probably of spinal origin. In this study, the effect of low ic doses of RX 77368 on afferent impulse activity in splanchnic single fibers was investigated. The cisterna magna of overnight-fasted, urethan-anesthetized Sprague-Dawley rats was acutely cannulated, and fine splanchnic nerve twigs containing at least one fiber responsive to mechanical probing of the stomach were isolated at a site immediately distal to the left suprarenal ganglion. Unit mechanoreceptive fields were encountered in all portions of the stomach, both superficially and in deeper layers. Splanchnic afferent unit impulse activity was recorded continuously during basal conditions and in response to consecutive ic injections of saline and RX 77368 (15-30 min later; 1.5 or 3 ng). Basal discharge rates ranged from 0 to 154 impulses/min (median = 10.2 impulses/min). A majority of splanchnic single units with ongoing activity increased their mean discharge rate by >/=20% after ic injection of RX 77368 at either 1.5 ng (6/10 units; median increase 63%) or 3 ng (19/24 units; median increase 175%). Five units lacking impulse activity in the 5-min before ic RX 77368 (3 ng) were also excited, with the onset of discharge occurring within 1.0-5.0 min postinjection. In units excited by ic RX 77368, peak discharge occurred 15.6 +/- 1.3 min after injection and was followed by a decline to stable activity levels +info)

Circadian and other rhythmic activity of neurones in the ventromedial nuclei and lateral hypothalamic area. (2/282)

1. The frequency of firing was simultaneously recorded from single neurones of the ventromedial nuclei (VMN) and the lateral hypothalamic area (LHA) in urethane anaesthetized rats for many hours. 2. There were circadian changes of VMN and LHA neurone activity. The pattern of this circadian rhythm is as follows: throughout the day LHA neurones show higher activity than that of VMN, as indicated by higher frequency and more fluctuations in their rates of firing. In late afternoon the discharge rate of LHA neurones increases further, showing oscillations of short duration. In the early evening hours LHA neurone activity gradually goes down, as the VMN neurones become active. Throughout the night, VMN neurones are more active than those of LHA, just the opposite of the day period. In early morning hours VMN neurones gradually become quiet, while LHA neurones begin to show activity. 3. Superimposed on the circadian rhythm, at certain periods of the day, VMN and LHA neurones showed short duration oscillations in rate of firing, roughly every 7-15 sec and every 3-5 min. 4. Activities in neurones of the VMN and LHA were reciprocally related; a decrease in firing rate of one was associated with an increase in the other. This phenomenon was shown clearly by analysis of auto- and cross-correlation functions of firing patterns of VMN and LHA neurones. 5. The effects of stimulations of the prefrontal cortex and splanchnic afferents on VMN and LHA neurones depended on the basic firing frequency, thus they varied with the time of day. Definite relationships exist between basic firing frequency of a cell and the magnitude of changes evoked by these stimuli. Reactions of VMN and LHA neurones were the opposite in most instances. Septal stimulations (at more than 10/sec) always produced inhibition of LHA neurone activity. 6. Intravenous injection of glucose inhibited LHA neurones and accelerated firing of VMN cells. This was true during the day period as well as at night when background activities of VMN and LHA neurones were different from that of the day. 7. Stimulation of the septal area with subthreshold pulses at a low rate (1-0.3/sec) suppressed or altered oscillations in firing frequency of LHA neurones. Severance of connection between LHA and structures caudal thereto had no effect on LHA neurone firing rates or rhythms. Sections between the septal area and LHA, however, abolished or greatly altered the oscillatory rhythms of LHA cell activity, although spontaneous discharges continued at a somewhat lower rate for periods of hours. 8. Stimulation of suprachiasmatic nuclei with weak intensity and low frequency also changed oscillatory fluctuations in firing of LHA neurones. 9. Possible origins of circadian rhythm and oscillations of short duration in firing pattern of VMN and LHA neurones were discussed.  (+info)

Effects of adrenomedullin and PAMP on adrenal catecholamine release in dogs. (3/282)

We examined the effects of proadrenomedullin-derived peptides on the release of adrenal catecholamines in response to cholinergic stimuli in pentobarbital sodium-anesthetized dogs. Drugs were administered into the adrenal gland through the phrenicoabdominal artery. Splanchnic nerve stimulation (1, 2, and 3 Hz) and ACh injection (0.75, 1.5, and 3 microgram) produced frequency- or dose-dependent increases in adrenal catecholamine output. These responses were unaffected by infusion of adrenomedullin (1, 3, and 10 ng. kg-1. min-1) or its selective antagonist adrenomedullin-(22-52) (5, 15, and 50 ng. kg-1. min-1). Proadrenomedullin NH2-terminal 20 peptide (PAMP; 5, 15, and 50 ng. kg-1. min-1) suppressed both the splanchnic nerve stimulation- and ACh-induced increases in catecholamine output in a dose-dependent manner. PAMP also suppressed the catecholamine release responses to the nicotinic agonist 1, 1-dimethyl-4-phenylpiperazinium (0.5, 1, and 2 microgram) and to muscarine (0.5, 1, and 2 microgram), although the muscarine-induced response was relatively resistant to PAMP. These results suggest that PAMP, but not adrenomedullin, can act as an inhibitory regulator of adrenal catecholamine release in vivo.  (+info)

Effects of 17beta-estradiol on the baroreflex control of sympathetic activity in conscious ovariectomized rats. (4/282)

The effects of chronic treatment with 17beta-estradiol on baroreflex control of sympathetic activity were examined in conscious unrestrained ovariectomized rats. Baroreflex function was evaluated by logistic sigmoidal analysis of the relationships between changes in mean arterial pressure (MABP) and changes in heart rate (HR) and splanchnic nerve activity (SNA) when MABP was rapidly increased to 150 mmHg by intravenous phenylephrine after its reduction to 50 mmHg by intravenous nitroprusside. These baroreflex function curves were similar in vehicle- and estradiol-treated rats. However, after a 30-min infusion of vasopressin in vehicle-treated rats, the curve for HR was shifted downward, and the upper plateau and maximum gain for the SNA curve were reduced. These effects were abolished by estradiol. A 30-min phenylephrine infusion had no effect on the baroreflex curves. Thus estrogen can modulate the action of vasopressin on baroreflex control of sympathetic outflow and thereby participate in cardiovascular regulation.  (+info)

Involvement of NMDA and non-NMDA receptors in transmission of spinal visceral nociception in cat. (5/282)

AIM: To study the role of N-methyl-D-aspartic acid (NMDA) and non-NMDA receptors in processing nociceptive visceral information in the spinal cord. METHODS: The firing of spinal dorsal horn neurons to colorectal distension (3-15 kPa, 20 s) by inflation with air of latex balloon was recorded in 25 anesthetized cats. RESULTS: 1) According to the patterns of responses to colorectal distension, the neurons with increase and decrease in firing were classified as excitatory and inhibitory, respectively. The former consisted of 17 short-latency abrupt (SLA) neurons, 11 short-latency sustained (SLS) neurons, 9 long-latency (LL) neurons. The 15 inhibited (Inh) neurons were recorded. 2) Microelectrophoretic administration of NMDA, quisqualic acid (QA), and kainic acid (KA) activated 67.6%, 78.4%, and 59.5% of the colorectal distension-excited neurons tested. Also, 60%, 86.7%, and 53.3% of Inh neurons were activated by these 3 amino acids. 3) Colorectal distension-induced excitatory responses were reduced by 35% +/- 10% and 65% +/- 14% by a selective NMDA receptor antagonist d,l-2-amino-5-phosphonovalerate (APV) and a selective non-NMDA receptor antagonist 6,7-dinitro-quinoxaline-2,3-dione (DNQX), respectively. Such DNQX-induced inhibition was significantly more potent than that by APV (P < 0.05). Colorectal distension-induced inhibitory responses were partially relieved by 30%-50% in 3/7 Inh neurons by DNQX, but not APV. CONCLUSION: Both NMDA and non-NMDA receptors are involved in transmission and/or modulation of spinal visceral nociceptive information and non-NMDA receptors may play more important role than NMDA receptors.  (+info)

Rhythmic sympathetic nerve discharges in an in vitro neonatal rat brain stem-spinal cord preparation. (6/282)

To understand the origination of sympathetic nerve discharge (SND), I developed an in vitro brain stem-spinal cord preparation from neonatal rats. Ascorbic acid (3 mM) was added into the bath solution to increase the viability of preparations. At 24 degrees C, rhythmic SND (recorded from the splanchnic nerve) was consistently observed, but it became quiescent at <16 degrees C. Respiratory-related SND (rSND) was discernible and was well correlated with C(4) root activity. Power spectral analysis of SND revealed a dominant 2-Hz oscillation. In most preparations (86%), such oscillation was persistent, whereas it only slightly reduced its magnitude after isolation from the brain stem. The removal of neural structures rostral to the superior cerebellar artery (equivalent to the level of facial nuclei) reduced rSND, increased tonic SND, but did not affect the temporal coupling between SND and C(4) root activity. Our data suggest a prominent contribution of SND from the neural mechanisms confined within the neonatal rat spinal cord. This ascorbic acid-enhanced in vitro preparation is a very useful model to study neural mechanisms underlying sympathorespiratory integration.  (+info)

Role of ET(B) receptors and nitric oxide in adrenal catecholamine secretion in anesthetized dogs. (7/282)

We examined the effects of sarafotoxin 6c (S6c), an endothelin-B (ET(B)) receptor agonist, on adrenal catecholamine secretion in response to cholinergic stimuli in pentobarbital sodium-anesthetized dogs. Drugs were administered intra-arterially into the adrenal gland through the phrenicoabdominal artery. Infusion of S6c attenuated increases in adrenal catecholamine output induced by splanchnic nerve stimulation. The inhibitory effect of S6c on the catecholamine secretion response was suppressed with a selective ET(B) receptor antagonist N-cis 2, 6-dimethylpiperidinocarbonyl-L-gamma-methylleucyl-D-1-methoxycarbonyl tryptophanyl-D-norleucine (BQ-788), a nitric oxide synthase (NOS) inhibitor N(omega)-nitro-L-arginine methyl ester, and a neuronal NOS inhibitor 7-nitroindazole monosodium salt (7-NINA). Similar results were obtained with the catecholamine secretion response induced by injection of ACh. 7-NINA alone did not affect these catecholamine secretion responses. These results suggest that ET(B) receptors play an inhibitory role in adrenal catecholamine secretion by activating neuronal NOS, whereas neuronal NOS is unlikely to be involved in regulation of adrenal catecholamine secretion in the absence of simultaneous ET(B) receptor stimulation.  (+info)

Bilateral thoracoscopic splanchnicectomy: effects on pancreatic pain and function. (8/282)

OBJECTIVE: To evaluate prospectively the effect of bilateral thoracoscopic splanchnicectomy on pancreatic pain and function. SUMMARY BACKGROUND DATA: Severe pain is often the dominant symptom in pancreatic disease, despite a wide variety of methods used for symptom relief. Refinement of thoracoscopic technique has led to the introduction of thoracoscopic splanchnicectomy in the treatment of pancreatic pain. METHODS: Forty-four patients, 23 with pancreatic cancer and 21 with chronic pancreatitis, were included in the study and underwent bilateral thoracoscopic splanchnicectomy. Effects on pain (visual analogue scale) and pancreatic function (standard secretin test, basal serum glucose, plasma insulin, and C-peptide) were measured. RESULTS: Four patients (9%) required thoracotomy because of bleeding. There were no procedure-related deaths. The mean duration of follow-up was 3 months for cancer and 43 months for pancreatitis. Pain relief was evident in the first postoperative week and was sustained during follow-up, the average pain score being reduced by 50%. All patients showed a decrease in consumption of analgesics. Neither endocrine nor exocrine function was adversely affected by the procedure. CONCLUSIONS: Bilateral thoracoscopic splanchnicectomy is beneficial in the treatment of pancreatic pain and is not associated with deterioration of pancreatic function.  (+info)

The greater splanchnic nerves are paired structures formed from preganglionic sympathetic nerve fibres which pass without synapsing through the paravertebral ganglia of segments five to nine on either side of the spinal column. The fibres from the ganglia converge to form a nerve which runs inferiorly through the thorax within the posterior mediastinum. It is closely apposed to the vertebral bodies of the spinal column. On the left, it is slightly lateral to the azygous vein. On the right, it is lateraly to the hemiazygous system and the aorta.. The greater splanchnic nerves pierce the diaphragmatic crura on both sides at the level of L1. Then, the fibres pass to onto the surface of the aorta where they synapse with postganglionic fibres within the coeliac ganglia.. Last reviewed 01/2018 ...
Author: Sulochana Sakthivel, K.Y.Manjunath. Category: Anatomy. [Download PDF]. Abstract:. Background: Thoracic splanchnicectomy is an important surgical procedure for the management of upper abdominal pain especially in cases of chronic pancreatitis or pancreatic cancer.

Effects of electrical stimulation of the left greater splanchnic nerve (SPL) on T1-T5 spinothalamic (STT) neurons were determined. Eighty-five STT neurons were studied in 36 anesthetized monkeys (Macaca fascicularis). All neurons were excited by manipulation of their somatic receptive fields and by electrical stimulation of cardiopulmonary (CP) sympathetic afferent fibers. SPL stimulation excited 63 (74%) STT neurons. There was an increasing percentage of cells with SPL input at more caudal segments and in deeper laminae. Both SPL and CP sympathetic stimulation elicited early or both early and late responses. Latencies to cell activation were usually shorter for CP sympathetic stimulation than for SPL stimulation (5.4 +/- 0.8 versus 11.3 +/- 2.0 ms for early responses and 44.2 +/- 4.2 versus 111.0 +/- 6.6 ms for late responses). The maximum number of spikes per SPL or CP sympathetic stimulus was determined. In the T2 and T3 segments, early responses to CP sympathetic stimulation were ...

We have demonstrated previously that spontaneously diabetic BB-Wistar rats exhibit decreased adrenal medullary catecholamine secretion in response to splanchnic nerve terminal stimulation. We hypothesized that this abnormality is caused by changes in the sensitivity of the adrenomedullary chromaffin cells to acetylcholine (ACh). To study this hypothesis, we isolated adrenal glands from control and spontaneously diabetic BB-Wistar rats, perfused them with ACh, and measured catecholamine secretion. Adrenal catecholamine release in response to ACh was significantly decreased at 2, 8, and 16 weeks after the onset of diabetes compared with age-matched, nondiabetic control rats. Catecholamine release in response to perfusion with 20 mM K+ was the same in adrenals from diabetic and control rats. The decreased responsiveness of diabetic rat adrenals to perfusion with ACh was significantly correlated with a decrease in the release of catecholamines in response to splanchnic nerve stimulation. A similar ...

The effect of supradiaphragmatic splanchnicectomy on the blood pressure of 294 hypertensive patients followed for 10 to 18 months after surgery is compared with the effects of nonspecific medical management in a control group of 79 patients similarly studied. The data are presented in simple graphic form. It is concluded that 29 per cent of the hypertensive patients had reductions in blood pressure outside the range of spontaneous variation, that the vascular complications of hypertension decreased the likelihood of a good result, and that extension of the sympathetic ganglionectomy upward appeared to increase the frequency of good results without requiring a two-stage operation or producing significant postoperative orthostatic hypotension.. ...

TANK-binding kinase 1 (TBK1) is a non-canonical IKK family member and plays a critical role in innate immunity by modulating cytokine production, interferon, and NF-kB signaling. It is recently reported that TBK1 directly engages Akt survival signaling to support oncogenic Ras-driven transformation. TBK1 is also identified as a synthetic lethal partner in KRas mutant NSCLC through systematic RNA interference. In this study, we have characterized LSN3090729, a 4-aryl-2-aminopyrimidine derivative as a selective TBK1 kinase inhibitor. Biochemical and cellular analyses demonstrate that LSN3090729 is a potent TBK1 kinase inhibitor, and selectively inhibits TBK1 based on in vitro activities in biochemical assays developed with a panel of protein kinases. In Panc-1, a pancreatic tumor cell line with KRas mutation, LSN3090729 inhibits EGF-induced phosphorylation of AKT at both Thr308 and Ser473 sites. Pharmacokinetic analysis shows that LSN3090729 has an over 70% of oral bioavailability with an ...

I was bored so I made a very possibly bullshit quick analysis. Review of LSN showed 216 acceptances last cycle. Lets just assume 10% less applicants this year (totally made up for analysis purposes). We should then expect roughly 194 acceptances this year on LSN. So far there are 122 acceptances. 122/194 = 63% of the class has been filled. If there is 15% drop in applicants, we expect 184 acceptances. 122/184 = 66% of the class has been filled ...

The centrally induced effects of angiotensin II and substance P on the cardiovascular system and on neuronal efferent activity of the splanchnic, renal, and adrenal nerves were investigated in chronically instrumented conscious rats. The pressor responses to substance P injected into the lateral brain ventricle were accompanied by marked and short latency increases in heart rate, cardiac output, splanchnic, renal, and adrenal nerve activity, and a rise in plasma noradrenaline and adrenaline. Behaviorally, an arousal-type reaction was observed. In contrast, the pressor responses to intracerebroventricular angiotensin II were associated with initial decreases in heart rate, cardiac output, splanchnic, renal, and adrenal nerve activity, and a fall in plasma noradrenaline at the time of the maximal blood pressure increase. In some but not all animals, a second blood pressure peak associated with increases in heart rate and splanchnic nerve activity was observed after several minutes. Incomplete ...
TY - JOUR. T1 - Both orexin 1 and 2 receptors mediate orexin a induced sympathoexcitaton and increase in phrenic nerve activity. AU - Shahid, Israt Z.. AU - Rahman, Ahmed A.. AU - Pilowsky, Paul M.. PY - 2011. Y1 - 2011. N2 - Orexin containing neurons in the lateral hypothalamus project to all levels of the spinal cord including dorsal horn, intermediolateral cell column and ventral horn. This study was undertaken to determine the role of orexin receptors in the spinal cord. Experiments were conducted on anesthetized, vagotomised and artificially ventilated Sprague-Dawley rats (n = 17). Intrathecal injection of orexin A (OX-A) (20 nmol) caused increase in mean arterial pressure (MAP), heart rate (HR), splanchnic sympathetic nerve activity (sSNA) and phrenic nerve activity (PNA). But orexin receptor 1 antagonist, SB 334867 (200 nmol), was unable to affect the resting level of cardio-respiratory parameters when injected intrathecally. On the other hand SB 334867, injected 20 min before OX-A (20 ...

Pre-renal failure is normally the result of hypo-perfusion of the kidneys therefore you are looking for something that could reduce blood supply to the kidneys. Sepsis causes is drop in blood pressure so the kidneys wouldnt receive enough blood, or enough blood at the right pressure, to adequately perfuse the kidneys. The four other examples are arguably all examples of post-renal failure, that is characterised by blockage of renal drainage. Pyelonephritis causes inflammation and pus build up in the pelvis of the kidney preventing it from draining. Struvite stones also form in the renal pelvis. An enlarged prostate could stop bladder drainage causing urine to back up into the kidneys. Similarly, spinal cord damage at L5 could damage the parasympathetic nerves (aka pelvic splanchnic nerves) that exit the vertebral column S2-4. These nerves provide motor innervation to the bladder and their damage could cause urinary retention ...
Stimulation of the vomiting center results in the coordination of responses from the diaphragm, salivary glands, cranial nerves, and gastrointestinal muscles to produce the interruption of respiration and forced expulsion of stomach contents known as retching and vomiting. The vomiting center is stimulated directly by afferent input from the vagal and splanchnic nerves, the pharynx, the cerebral cortex, cholinergic and histamine stimulation from the vestibular system, and efferent input from the chemoreceptor trigger zone (CTZ). The CTZ is in the area postrema, outside the blood-brain barrier, and is thus susceptible to stimulation by substances present in the blood or cerebral spinal fluid. The neurotransmitters dopamine and serotonin stimulate the vomiting center indirectly via stimulation of the CTZ.. The 5-HT3 inhibitors are the most effective antiemetics and constitute the single greatest advance in the management of nausea and vomiting in patients with cancer. These drugs are designed to ...
1. Nine unoperated dogs snowed a rise of blood sugar dunng anaphylactic shock. In six of these dogs the rise was 60 mg. or over.. 2. Six dogs in which one adrenal had long previously been extirpated and the opposite splanchnic nerve cut, showed a low preliminary level of blood sugar, and a relative rise of blood sugar during anaphylaxis, but of less degree than in the unoperated animals. In no case was it greater than 52 mg.. 3. Anoxemia did not appear to be a complicating factor, as evidenced by determination of the oxygen content of the arterial blood before and during shock.. 4. The rise in blood sugar, which occurs in spite of the loss of adrenal activity, is probably due to the venous stasis of the liver seen in anaphylaxis in the dog, because this rise in blood sugar can be simulated in a normal non-sensitized dog by mechanically constricting the hepatic veins for a brief interval.. 5. There are, therefore, probably two factors responsible for the hyperglycemia associated with anaphylaxis ...
The LSN was identified in 95% of the cadaveric specimens. A direct coaptation of the LSN and SSN was possible in 45% of the specimens (n = 9) but not between the LSN and LPN in any of the specimens. Comparison of axonal counts among the three nerves did not show any significant difference. Good results from reinnervation of the major pectoral muscle (Medical Research Council grade ≥ 3) were observed in 70% (n = 7) of the patients who had undergone LSN to LPN transfer. ...

LSN used to be a favorite fuel stop of mine. Fast, easy and cheap. Then slowly over the last several years LSN has allowed the price of Jet A to slowly creep up higher and higher until, now it is one of the more expensive places to refuel. Used to be that LSN was about 10-20% higher than the lowest price you could find in the state. Now it is 30-40% higher. Currently at $4.00/gal where Temecula is $2.60. In the old days prices would be in the $3.00 range - a full 25% less and 1 dollar. On a 200 gallon fill-up - that adds up and puts it into the not worth it anymore category ...

To test the hypothesis that the hypotensive action of urapidil is in part related to a direct action on the brain, the central (intracerebroventricular) and peripheral (intravenous) effects of urapidil were studied and compared with those obtained with clonidine and prazosin. All studies were conducted in conscious, chronically instrumented stroke-prone spontaneously hypertensive rats (SHRSP). Efferent sympathetic nervous system activity was estimated by means of a bipolar electrode implanted on the splanchnic nerve. Only clonidine, administered intracerebroventricularly and intravenously, decreased sympathetic nerve activity. Urapidil and prazosin either did not affect sympathetic nerve activity after central administration or increased it after peripheral administration at low and high doses, respectively. Centrally administered urapidil and prazosin lowered blood pressure but also blocked the response to intravenously administered phenylephrine; this result suggests a peripheral effect. ...
In dogs caused experimental strangulation obstruction by ligation of the upper small intestine together with the mesentery measuring 80 cm in length, adrenal venous blood was observed for the secretion rate of adrenaline and noradrenaline by the fluorimetric method. Increase of adrenal medullary secretion was not induced by the continued strangulation alone. However, when the strangulation was released three hours after the onset, the secretion rate of adrenaline and noradrenaline increased rapidly. When 250 mg of kanamycin was injected into the strangulated intestinal loop and the obstruction was released three hours later, the increase of adrenal medullary secretion was slight. When the strangulated intestinal loop was resected and anastomosed three hours after the onset of obstruction, the adrenal medullary secretion showed no increase. When strangulation was released after resection of the greater and lesser splanchnic nerves on the side wherefrom the adrenal venous blood was drawn, any ...
