The temporal relationships among selected correlates of hepatocellular damage were investigated in cordotomized, hypothermic rats intoxicated with carbon tetrachloride (CCl4). Rats were spinally transected between C6 and C7 and allowed to become hypothermic. CCl4 (1.25 ml/kg ip) was administered as

The effects of N-methyl carbamate pesticides on the photic after discharge (PhAD) of flash evoked potentials (FEPs) and the relationship between inhibition of brain cholinesterase (ChE) activity and the PhAD were evaluated. FEPs were recorded in Long Evans rats treated with physostigmine (s.c.) 0,

Diazinon is an organophosphate (OP)-based, anticholinesterase insecticide that irreversibly inhibits acetylcholinesterase activity and produces cholinergic stimulation in central nervous system (CNS) and peripheral tissues. Our laboratory has found that OPs administered orally in rats induce a

Arachidonic acid, a fatty acid component of neuronal cell membranes, forms the backbone of endogenous ligands of the endocannabinoid system. The lipid nature of this system may make it particularly susceptible to changes in fat content of the diet, which may, in turn, affect endocannabinoid tone and

To investigate the mechanism(s) involved in chlordecone (CLD)-induced hypothermia, we examined colonic (Tcol) and tail skin (Tsk) temperatures, preferred ambient temperature (Ta), evaporative water loss, and metabolic rate following CLD exposure in the rat. Single ip dosages (0, 50, and 75 mg/kg) in

Organophosphate (OP) and carbamate (CB) insecticides inhibit cholinesterase (ChE) activity and induce acute hypothermia in adult rats. Studies showed that juveniles are generally more susceptible to neurotoxic insult than adults. However, little is known concerning the effects of OP and CB

Toluene, an industrial organic solvent, is voluntarily inhaled as drug of abuse. Toluene has been shown to inhibit the nicotinic acetylcholine receptors. Nicotinic receptors play an important role in brain development during brain growth spurt and early adolescence. The long-term effects of neonatal

Oral chlorpyrifos (CHP) induces hypothermia followed by a fever that persists for several days in the rat. To understand the neuro-immune mechanisms of CHP-induced fever, we compared the tolerance and cross-tolerance between CHP and the fever elicited by lipopolysaccharide (LPS) (Escherichia coli).

Oral exposure to chlorpyrifos (CHP) in the rat results in an initial hypothermic response followed by a delayed fever. Fever from infection is mediated by the release of cytokines, including interleukin-6 (IL-6) and tumor necrosis factor (TNF alpha). This study determined if the CHP-induced fever

Chronic exercise conditioning has been shown to alter basal thermoregulatory processes (change in thermoregulatory set point) as well as the response to infectious fever Chlorpyrifos (CHP), an organophosphate insecticide, also affects thermoregulation, causing an acute period of hypothermia followed

Male, albino rats of the F-344/N strain and mice of the B6C3F1 strain were dosed by gavage, 5 days per week for a toal of 22 doses with 0.03--30 mg/kg of FireMaster FF-1, 0.168-16.8 Mg/kg of 2,4,5,2',4',5'-hexabromobiphenyl (HBB), or corn oil vehicle. A battery of tests was administered at the end

Hypothermia is a commonly reported thermoregulatory response in rodents acutely exposed to organophosphates (OP); however, our laboratory has recently found a delayed hyperthermic response following the initial hypothermia when exposed to the OP, chlorpyrifos. It is well known that rodents display

Pyraclostrobin is a strobilurin fungicide that inhibits mitochondrial complex III of fungal and mammalian cells. In toxicity studies that were used to estimate the safety factor, pyraclostrobin was added to animal feed or to aqueous vehicles. However, foods containing residues of pyraclostrobin and

Little is known about the effects of physical activity (i.e., exercise training) on susceptibility to environmental toxicants. Chlorpyrifos (CHP), an organophosphate (OP) insecticide, affects thermoregulation, causing an acute period of hypothermia followed by a delayed fever. Since exercise

The development of high throughput biochemical screens could be useful to assess the broad spectrum of physiological effects of environmental toxicants. To explore the prospect of using a screen in an in vivo exposure scenario, we applied a commercially available multianalyte profile (MAP) of 58
