Impaired respiratory muscle function in chemical plant workers producing chlorfenvinphos. (1/8)

All employees of a chemical plant division producing chlorfenvinphos were studied, i.e. 35 males aged 25-57 years (mean 42.1); their employment period ranged from 1-15 years (mean 9.0). Chronic bronchitis was diagnosed in 13 workers (37.1%). Mean air chlorfenvinphos concentrations in the work environment estimated with gas-liquid chromatography were from 0.0008-0.0018 mg/m3 (maximum allowable concentration according to Polish standards is 0. 01 mg/m3). The activity of erythrocyte acetylcholinesterase was similar to that observed in people who were not exposed to chemicals, however, a slightly lowered activity of plasma cholinesterase in the studied population was evidently the result of mild liver impairment. Spirometric investigations performed in the studied workers revealed slight alterations manifested by increased intrathoracic gas volume (ITGV) (the value of the index was 138.6% of the mean value, 24 workers with an abnormally high index), as well as by decreased specific airway conductance (sGaw); its mean value in the studied group was 58.5% of the mean standard (11 people showed an abnormal index). Substantial functional changes were found in the respiratory muscles. Maximal inspiratory pressures (MIP = 97. 2 +/- 28.3 cm H2O) as well as maximal expiratory pressures (MEP = 113.9 +/- 44.2 cm H2O) in the studied group were significantly lower (p < 0.01) as compared to those observed in the control group (MIP = 120.7 +/- 31.7; MEP = 154.4 +/- 40.2 cm H2O) of 22 males having similar cigarette smoking habit, without occupational exposure to chemicals. It was also found that the people who had worked for more than 10 years under conditions of exposure to chlorfenvinphos showed significantly lower (p < 0.05) values of maximal inspiratory pressure (87.2 +/- 28.06 cm H2O, n = 17) compared to the workers whose period of employment was shorter than 10 years (106.6 +/- 26.8 cm H2O, n = 18). The two groups were comparable with regard to age and smoking habits. The values of maximal expiratory pressures were similar in both groups. No essential disturbances in neuro-muscular transmission were observed; only in 3 workers (8.5%) the electrostimulating myasthenic test showed some disturbances in neuro-muscular transmission. It seems that respiratory muscles impairment in humans exposed to chlorfenvinphos results from changes in the metabolism and structure of muscles, and partly from lung hyperinflation.  (+info)

Hyposensitivity to amphetamine following exposure to chlorphenvinphos--protection by amphetamine preexposure. (2/8)

We investigated the effect of an acute exposure to chlorphenvinphos (CVP), an organophosphate anticholinesterase, on amphetamine-induced open-field locomotion in rats. CVP was administered in a single i.p. dose of 1.0 mg/kg (1/10 of the LD50). All animals were challenged with 1.0 mg/kg amphetamine (AMPH) three weeks after the CVP exposure, i.e. after a time sufficient for acetylcholinesterase recovery. Some rats were also given AMPH three weeks before the CVP exposure. In rats challenged with AMPH only once after the CVP exposure, AMPH-induced open-field locomotion was significantly reduced. Such an effect was not observed in rats given AMPH three weeks before the CVP exposure. The results suggest that a single CVP exposure may result in persistent dopaminergic hyposensitivity, and that an amphetamine pretreatment may protect the rat against this effect.  (+info)

Behavioural responsiveness to amphetamine or scopolamine following repeated exposure to chlorphenvinphos in rats. (3/8)

A number of reports indicate that exposure to organophosphates (OPs), inhibitors of acetylcholinesterase (AChE), may result in long-lasting neurobehavioural alterations suggestive of an increased cholinergic tone. It is known that rats with cholinergic hyperreactivity are behaviourally hyposensitive to cholinergic antagonists and dopaminergic agonists. The purpose of the present study was to find out whether a similar trait would develop in rats exposed to chlorphenvinphos (CVP), an OP pesticide, in the past. The rats were given ten daily i.p. injections of CVP at doses of 0.5 mg/kg (group P-0.5) or 1.0 mg/kg (group P-1.0). The locomotion stimulating effect of i.p. injection of 1.0 mg/kg amphetamine (AMPH), or 0.7 mg/kg scopolamine (SCOP), was assessed on postexposure day 21 (group P-0.5) or 42 (group P-1.0), i.e. after a time sufficient for AChE recovery. The assessment revealed that in group P-1.0 the behavioural response to AMPH and SCOP was significantly depressed. In rats of the P-0.5 group, however, the behavioural response to each of the drugs was increased. The results suggest that, depending on the exposure level, contrasting alterations in some neurotransmitter systems may be induced by repeated exposure to CVP.  (+info)

Electroretinographic changes induced by organophosphorus pesticides in rats. (4/8)

Electroretinographic changes induced by organophosphorus pesticides (OPs) were studied in rats. Male Wistar rats were intraperitoneally injected with fenthion, chlorpyrifos, fenitrothion, dichlorvos or chlorfenvinphos at doses of 0.01 mmol/kg and/or 0.05 mmol/kg. The electroretinogram (ERG) was recorded at 5 hours and 2 days after the administration, and brain and retinochoroid cholinesterase (ChE) activities was assayed at 3 days after the injections. The brain and retinochoroid ChE activities were reduced in rats treated with the OPs. Notably, the reduction of ChE activities by fenthion, chlorpyrifos and dichlorvos were similar. The administration of OPs induced a change in the ERG, characterized by alteration of the amplitudes of a- and b-waves. Nevertheless the ChE activities in the brain and retinochoroid were inhibited by all of the OPs, the OPs affected the amplitude of ERG differently. Fenthion and chlorpyrifos decreased the amplitudes; dichlorvos and chlorfenvinphos increased; and fenitrothion transiently decreased at 5 hours but increased 2 days after the injection. These results indicate that a factor or factors other than inhibition of ChE activities contributes to the alteration of ERG induced by OPs.  (+info)

Effects of stress pretreatment on the dynamics of blood cholinesterase activity after exposure to an organophosphorus pesticide in the rat. (7/8)

A single i.p. administration of 1.0 mg/kg of chlorphenvinphos (CVP), an organophosphorus pesticide, results in an acute stress response, evidenced by a marked (6-7 fold) rise in plasma corticosterone (CORT) concentration, and a diminished behavioural sensitivity to amphetamine (AMPH) three weeks postexposure. Surprisingly, in rats subjected to a single series of inescapable electric footshocks (60 10 msec triplets of 3.0 mA, 2 msec, square pulses during 20 min - IF ) two weeks prior to the CVP exposure, these effects are not observed. It has been assumed that the reduced effectiveness of CVP might be related to some persisting alterations in the functional state of the cholinergic system. The aim of the present work was to discover whether and in what way the IF pretreatment affects i) the cholinesterase activity in blood, and ii) the dynamics of the alterations in the cholinesterase (ChE) activity following the CVP exposure. The experiments were performed on 3 mo. old, male Wistar rats. In the first experiment, the blood samples were taken from the tail vein 15, 60 and 180 min after the IF. In the second experiment, the rats were pretreated with IF and 14 days later given 1.0 mg/kg of CVP i.p. Blood samples were taken 15 min, 60 min, 180 min, 24 h, 7 days, and 14 days after the CVP exposure. In the first experiment no differences in the ChE activity in plasma (pChE) and erythrocytes (rbcChE) were found between the shocked and control rats. In the second experiment, however, in rats pretreated with IF the rbcChE activity of was reduced by CVP less and pChE activity returned to normal faster than in rats not pretreated with IF. The results confirm that exposure to IF, a nonchemical stressor, induces some long-lasting adaptive changes which render the cholinergic system less susceptible to the harmful action of ChE inhibitors. It has been hypothesized that the changes consist in an increase of the antioxidant potential in blood and possibly other tissues.  (+info)

Sites of methylation of DNA bases by the action of organophosphorus insecticides in vitro. (8/8)

Methylation in vitro of DNA by three methyl-14C-labelled organophosphorus insecticides has been studied. The ability of methylbromphenvinphos, methylparathion and malathion to methylate N-7 of guanine in DNA can be expressed as 100:40:15. Among the methylation products, no O6-methylguanine, a known mutagen, was found. Both in the reaction with dsDNA and with ssDNA 7-methyl-guanine was the main methylation product. However, all methyl derivatives of adenine (3-methyladenine, 1-methyladenine and 7-methyladenine) constituted about 40% and 50% of all methylation products in the case of dsDNA and ssDNA, respectively. The only methyl derivative of pyrimidine we have identified was 3-methylcytosine. In the case of dsDNA 3-methylcytosine appeared in small amounts but in the alkylated ssDNA 3-methylcytosine C constituted about 20% of all alkylation products.  (+info)

Recent organic fertilizer treatments (cow manure, pig slurry, composts, or green manure) simultaneously increase insecticide adsorption onto soil and the insecticide soil persistence, indicating a mechanism of slow release of insecticide into soil by the organic matter. This occurred in sugar beet crops with aldicarb, thiofanox and imidacloprid; also, in leek, cauliflower and brussels sprouts crops with chlorpyrifos and chlorfenvinphos. In contrast, organic fertilizer treatments applied once or repeatedly in the past, have no significant influence on adsorption or persistence of insecticides; the same is observed for the old soil organic matter, when its soil concentrations change in limited ranges ...

I am a chemical engineer, so I will talk about and outline my reasoning about this in engineering terms, sensors, control systems, feedback, and that sort of thing. This is not to imply any type of design as ID proponents consider it. That is simply how I think of and understand physiology, just the same as any other chemical plant, a very complex chemical plant with exquisite controls most of which we have no idea how they work, what the design parameters are, what parameter is being controlled to do what and under what circumstances. Hacking into the control system of a complex chemical plant and perhaps bypassing the safety systems (when you dont know what is/is not a safety system) is not something to be done casually. That is how I see a lot of medicine, the same as trying to hack into a chemical plant where none of the pipes or wires are labeled as to what they are carrying, where they are coming from or where they are going, you dont know what the control system is based on, or even ...

Hyposensitivity to vasopressin is a well documented phenomenon in animals with portal hypertension and patients with cirrhosis subject to haemorrhage. Haemorrhage is associated with the endogenous release of bradykinin, which may subsequently stimulate the formation of nitric oxide (NO). The present study investigated the relative contribution of NO synthase (NOS) isoforms and the role of bradykinin in the pathogenesis of splanchnic hyposensitivity to a long-acting vasopressin analogue, glypressin, in rats with portal hypertension induced by partial portal vein ligation (PVL). At 14 days after the operation, systemic and portal haemodynamics were measured in stable or bleeding PVL rats receiving an intravenous infusion of glypressin (0.07 mg/kg). In the treatment groups, NG-nitro-L-arginine methyl ester (L-NAME; a non-selective NOS inhibitor), L-canavanine (a specific inhibitor of inducible NOS) or HOE 140 (a bradykinin B2 receptor antagonist) was administered 45 min before the infusion of ...

We have determined the solution structure of an albumin binding domain of protein G, a surface protein of group C and G streptococci. We find that it folds into a left handed three-helix bundle similar to the albumin binding domain of protein PAB from Peptostreptococcus magnus. The two domains share 59% sequence identity, are thermally very stable, and bind to the same site on human serum albumin. The albumin binding site, the first determined for this structural motif known as the GA module, comprises residues spanning the first loop to the beginning of the third helix and includes the most conserved region of GA modules. The two GA modules have different affinities for albumin from different species, and their albumin binding patterns correspond directly to the host specificity of C/G streptococci and P. magnus, respectively. These studies of the evolution, structure, and binding properties of the GA module emphasize the power of bacterial adaptation and underline ecological and medical ...

In blood, these agents are transported by human serum albumin (HSA) which has a profound impact on the pharmacokinetic and pharmacodynamic properties of many therapeutic drugs and xenobiotics. By combination of various spectroscopic methods, the present contribution is aimed to elucidate how nonesterified fatty acids (FAs), the primary endogenous ligands of HSA, affect the binding properties of harmane and norharmane.

The biological mechanism for the thinning is not entirely known, but it is believed that p,p'-DDE impairs the shell gland's ability to excrete calcium carbonate onto the developing egg.[7][9][10][11][12] Multiple mechanisms may be at work, or different mechanisms may operate in different species.[7] Some studies have shown that although DDE levels have fallen dramatically, eggshell thickness remains 10-12 percent thinner than before DDT was first used.[13]. Some studies have indicated that DDE is an endocrine disruptor[14] and contributes to breast cancer, but more recent studies provide strong evidence that there is no relationship between DDE exposure and breast cancer.[15] What is more clear is that DDE is a weak androgen receptor antagonist and can produce male genital tract abnormalities.[16][17]. Animal studies show that organochlorine pesticides-such as DDE-are neurotoxic, cause oxidative stress, and damage the brain's dopaminergic system.[18]. ...
... (DDD) is an organochlorine insecticide that is slightly irritating to the skin.[1] DDD is a metabolite of DDT.[2] DDD is colorless and crystalline;[3] it is closely related chemically and is similar in properties to DDT, but it is considered to be less toxic to animals than DDT.[4] The molecular formula for DDD is (ClC6H4)2CHCHCl2 or C14H10Cl4, whereas the formula for DDT is (ClC6H4)2CHCCl3 or C14H9Cl5. DDD is in the "Group B2" classification, meaning that it is a probable human carcinogen. This is based on an increased incidence of lung tumors in male and female mice, liver tumors in male mice, and thyroid tumors in male rats. Further basis is that DDD is so similar to and is a metabolite of DDT, another probable human carcinogen.[2] DDD is no longer registered for agricultural use in the United States, but the general population continues to be exposed to it due to its long persistence time. The primary source of exposure is oral ingestion of food.[5] 1946 is the ...
... is a widely used, broad-spectrum benzimidazole fungicide and a metabolite of benomyl. It is also employed as a casting worm control agent in amenity turf situations such as golf greens, tennis courts etc. and in some countries is licensed for that use only.[2] The fungicide is used to control plant diseases in cereals and fruits, including citrus, bananas, strawberries, pineapples, and pomes.[3] It is also controversially used in Queensland, Australia on macadamia plantations.[4] A 4.7% solution of carbendazim hydrochloride, sold as Eertavas, is marketed as a treatment for Dutch elm disease. Studies have found high doses of carbendazim cause infertility and destroy the testicles of laboratory animals.[5][6] Maximum pesticide residue limits (MRLs) have reduced since discovering its harmful effects. The MRLs for fresh produce in the EU are now between 0.1 and 0.7 mg/kg with the exception of loquat, which is 2 mg/kg.[7] The limits for more commonly consumed citrus and pome fruits are ...
... has little systemic absorption, and is considered safe for topical use in adults and children over the age of 2 months. The FDA has assigned it as pregnancy category B. Animal studies have shown no effects on fertility or teratogenicity, but studies in humans have not been performed. The excretion of permethrin in breastmilk is unknown, and breastfeeding is recommended to be temporarily discontinued during treatment.[11] According to the Connecticut Department of Public Health, permethrin "has low mammalian toxicity, is poorly absorbed through the skin, and is rapidly inactivated by the body. Skin reactions have been uncommon."[14] Excessive exposure to permethrin can cause nausea, headache, muscle weakness, excessive salivation, shortness of breath, and seizures. Worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdose may be confirmed by measurement of permethrin in serum or blood plasma.[15] Permethrin does not present any ...
Human exposure to methoxychlor occurs via air, soil, and water,[7] primarily in people who work with the substance or who are exposed to air, soil, or water that has been contaminated. It is unknown how quickly and efficiently the substance is absorbed by humans who have been exposed to contaminated air or via skin contact.[7] In animal models, high doses can lead to neurotoxicity.[7] Some methoxychlor's metabolites have estrogenic effects in adult and developing animals before and after birth.[7] One studied metabolite is 2,2-bis(p-hydroxyphenyl)-1,1,1-trichloroethane (HPTE) which shows reproductive toxicity in an animal model by reducing testosterone biosynthesis.[8][9] Such effects adversely affect both the male and female reproductive systems. It is expected that this "could occur in humans" but has not been proven.[7] While one study has linked methoxychlor to the development of leukemia in humans, most studies in animals and humans have been negative, thus the EPA has determined that it is ...
GV (IUPAC name: 2-(Dimethylamino)ethyl N,N-dimethylphosphoramidofluoridate) is an organophosphate nerve agent. GV is a part of a new series of nerve agents with properties similar to both the "G-series" and "V-series". It is a potent acetylcholinesterase inhibitor with properties similar to other nerve agents, being a highly poisonous vapour. Treatment for poisoning with GV involves drugs such as atropine, benactyzine, obidoxime, and HI-6.[1][2] ...
The four-membered ring in α-pinene 1 makes it a reactive hydrocarbon, prone to skeletal rearrangements such as the Wagner-Meerwein rearrangement. For example, attempts to perform hydration or hydrogen halide addition with the alkene functionality typically lead to rearranged products. With concentrated sulfuric acid and ethanol the major products are terpineol 2 and its ethyl ether 3, while glacial acetic acid gives the corresponding acetate ester 4. With dilute acids, terpin hydrate 5 becomes the major product. With one molar equivalent of anhydrous HCl, the simple addition product 6a can be formed at low temperature in the presence of ether, but it is very unstable. At normal temperatures, or if no ether is present, the major product is bornyl chloride 6b, along with a small amount of fenchyl chloride 6c.[5] For many years 6b (also called "artificial camphor") was referred to as "pinene hydrochloride", until it was confirmed as identical with bornyl chloride made from camphene. If more HCl is ...
While botulinum toxin is generally considered safe in a clinical setting, there can be serious side effects from its use. Most commonly, botulinum toxin can be injected into the wrong muscle group or spread from the injection site, causing paralysis of unintended muscles. Side effects from cosmetic use generally result from unintended paralysis of facial muscles. These include partial facial paralysis, muscle weakness, and trouble swallowing. Side effects are not limited to direct paralysis however, and can also include headaches, flu-like symptoms, and allergic reactions.[27] Just as cosmetic treatments only last a number of months, paralysis side-effects can have the same durations.[citation needed] At least in some cases, these effects are reported to dissipate in the weeks after treatment.[citation needed] Bruising at the site of injection is not a side effect of the toxin but rather of the mode of administration, and is reported as preventable if the clinician applies pressure to the ...
... is a poisonous diterpenoid found in the South American plant Ryania speciosa (Salicaceae). It was originally used as an insecticide.. The compound has extremely high affinity to the open-form ryanodine receptor, a group of calcium channels found in skeletal muscle, smooth muscle, and heart muscle cells.[1] It binds with such high affinity to the receptor that it was used as a label for the first purification of that class of ion channels and gave its name to it.. At nanomolar concentrations, ryanodine locks the receptor in a half-open state, whereas it fully closes them at micromolar concentration. The effect of the nanomolar-level binding is that ryanodine causes release of calcium from calcium stores as the sarcoplasmic reticulum in the cytoplasm, leading to massive muscular contractions. The effect of micromolar-level binding is paralysis. This is true for both mammals and insects.. ...
... is very toxic to cats which cannot tolerate the therapeutic doses for dogs.[7] This is associated with UGT1A6 deficiency in cats, the enzyme responsible for metabolizing cypermethrin. As a consequence, cypermethrin remains much longer in the cat's organs than in dogs or other mammals and can be fatal in large doses. In male rats cypermethrin was shown to exhibit a toxic effect on the reproductive system. After 15 days of continual dosing, both androgen receptor levels and serum testosterone levels were significantly reduced. These data suggested that cypermethrin can induce impairments of the structure of seminiferous tubules and spermatogenesis in male rats at high doses.[8] Long-term exposure to cypermethrin during adulthood is found to induce dopaminergic neurodegeneration in rats, and postnatal exposure enhances the susceptibility of animals to dopaminergic neurodegeneration if rechallenged during adulthood.[9] If exposed to cypermethrin during pregnancy, rats give birth to ...

Before DDT, malaria was successfully eliminated or curtailed in several tropical areas by removing or poisoning mosquito breeding grounds and larva habitats, for example by eliminating standing water. These methods have seen little application in Africa for more than half a century.[137] According to CDC, such methods are not practical in Africa because "Anopheles gambiae, one of the primary vectors of malaria in Africa, breeds in numerous small pools of water that form due to rainfall ... It is difficult, if not impossible, to predict when and where the breeding sites will form, and to find and treat them before the adults emerge."[138] The relative effectiveness of IRS versus other malaria control techniques (e.g. bednets or prompt access to anti-malarial drugs) varies and is dependent on local conditions.[34] A WHO study released in January 2008 found that mass distribution of insecticide-treated mosquito nets and artemisinin-based drugs cut malaria deaths in half in malaria-burdened Rwanda ...
When used in the central nervous system to alleviate neurological symptoms, such as rivastigmine in Alzheimer's disease, all cholinesterase inhibitors require doses to be increased gradually over several weeks, and this is usually referred to as the titration phase. Many other types drug treatments may require a titration or stepping up phase. This strategy is used to build tolerance to adverse events or to reach a desired clinical effect.[12] This also prevents accidental overdose and is therefore recommended when initiating treatment with drugs that are extremely potent and/or toxic (drugs with a low therapeutic index). ...
... can be broadly categorized as a cholinergic physiological antagonist, because it reduces the apparent activity of cholinergic neurons, but does not act at the postsynaptic ACh receptor. Vesamicol causes a non-competitive and reversible block of the intracellular transporter VAChT responsible for carrying newly synthesized ACh into secretory vesicles in the presynaptic nerve terminal. This transport process is driven by a proton gradient between cell organelles and the cytoplasm. Blocking of acetylcholine loading leads to empty vesicles fusing with neuron membranes, decreasing ACh release. ...
... s are a group of highly conserved G-protein coupled receptors from the adhesion G protein-coupled receptor family. These receptors were originally identified based on their ability to bind the spider venom alpha-latrotoxin.[1] This conserved family of membrane proteins has up to three homologues in chordate species, including humans.[2] The precise functions of latrophilins remain unknown.[2] Genetic defects in latrophilin genes have been associated with diseases such as attention-deficit hyperactivity disorder and cancer.[3] ...
... ( anticholinergic agent) is a group of substances that blocks the action of the neurotransmitter acetylcholine (ACh) at synapses in the central and the peripheral nervous system, and, in broad terms, neuromuscular junction.[1][2] These agents inhibit parasympathetic nerve impulses by selectively blocking the binding of the neurotransmitter acetylcholine to its receptor in nerve cells. The nerve fibers of the parasympathetic system are responsible for the involuntary movement of smooth muscles present in the gastrointestinal tract, urinary tract, lungs, and many other parts of the body;[3] cholinergic process otherwise by enhancing ACh function.[3] In broad terms, anticholinergics are divided into two categories in accordance with their specific targets in the central, peripheral nervous system and neuromuscular junction:[3] antimuscarinic agents, and antinicotinic agents (ganglionic blockers, neuromuscular blockers).[4] In strict terms, anticholinergic only comprises ...

... is an alkaloid found in Corydalis (Papaveraceae) and Dicentra, plants in the family Fumariaceae that can cause fatal poisoning in sheep and cattle.[citation needed] It has been shown to act as an acetylcholinesterase inhibitor,[1] and inhibits biosynthesis of dopamine via inhibition of the enzyme tyrosine hydroxylase.[2][3] Like apomorphine, it is reported to be an inhibitor of amyloid beta protein (Aβ) fiber formation, whose presence is a hallmark of Alzheimer's disease (AD). Bulbocapnine is thus a potential therapeutic under the amyloid hypothesis.[4] According to the Dorlands Medical Dictionary, it "inhibits the reflex and motor activities of striated muscle. It has been used in the treatment of muscular tremors and vestibular nystagmus".[5] A psychiatrist at Tulane University named Robert Heath carried out experiments on prisoners at the Louisiana State Penitentiary using bulbocapnine to induce stupor.[6] This work at Tulane inspired, and was continued parallel to, experiments ...

Although there are important benefits from the proper use of pesticides, like crop protection and prevention of human disease outbreaks, there are also risks associated with contamination of, for example, groundwater and surface-water resources, which can subsequently alter a human and environmental health. More importantly, pesticides are used almost everywhere - not only in agricultural fields, but also in homes, parks, schools, buildings, forests and roads. As a result, pesticides can be found in the air we breathe, the soil we grow crops in, the food we eat and the water we drink.. Pesticides have been linked to a wide range of human health hazards, ranging from short-term impacts to chronic impacts like cancer, reproductive harm and endocrine disruption. Pesticides can also have a dramatic environmental effect, e.g. damage agricultural land by harming beneficial insect species and soil microorganisms, weakening plant root system, harming worms which naturally limit pest population and ...
