Background and Objective: Fenvalerate is a component of the pyrethroid pesticide induces oxidative stress. This study was done to determine the effect of garlic extract (GE) and N-acetylcysteine (NAC) against fenvalerate-induced oxidative stress in the serum and testis tissue of rat. Methods: In this experimental study, 42 Wistar rats were randomly allocated into 7 groups including: control gr...

An in vivo rainbow trout (Salmo gairdneri) preparation was used to evaluate the gill uptake and toxicokinetics of [3H]fenvalerate ([R,S]-α-cyano-3-phenoxybenzyl [R,S]-2-[4-chloro-phenyl]-3-methylbutyrate), a synthetic pyrethroid insecticide. Fish were exposed to technical-grade fenvalerate (0.28 or 23 ng/L) or an emulsifiable-concentrate formulation (16 ng/L) for 36 to 48 h. No significant effe...

Pyrethroids are a class of neurotoxic pesticides with high selectivity for insects. Fenvalerate is a synthetic pyrethroid pesticide used to protect a variety of crops. Fenvalerate has been reported to exert deleterious effects on non target organisms including mammals. Recently, Fenvalerate was reported to cause liver damage in rats probably by generating oxidative stress while Quercetin, a pot...

Synergism of fenvalerate with piperonyl butoxide (PB), NIA-16388 (NIA), S-421, and MGK-264 on both susceptible (S) and fenvalerate-selected (FS) strains of diamondback moth, Plutella xylostella L, were determined in laboratory tests. Further, combinations of fenvalerate and these synergists were tested for their efficacies against resistant strain under field conditions in the Cameron Highlands...

PURPOSE The purpose of the study was to observe the effects of fenvalerate exposure on the semen quality of occupational workers. MATERIALS AND METHODS Thirty-two male workers who were exposed to fenvalerate and 46 male administrators in the office in the same pesticide factory were selected as the exposure group and internal control group, respectively, and 22 male administrators in a center...

Fenvalerate is a synthetic pyrethroid , widely used due to its high effective and low mammalian toxicity. Fenvalerate, dose equivalent to LD25 was administered orally for acute exposure and dose equivalent to LD5 for subchronic & chronic exposure to Wistar rats. Toxic effect of Fenvalerate observed in serum Lypase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), Cholinesterase...

OBJECTIVE To observe the effects of fenvalerate on calcium homeostasis in rat ovary. METHODS Female Sprague-Dawley rats were orally given fenvalerate at daily doses of 0.00, 1.91, 9.55, and 31.80 mg/kg for four weeks. The ovary ultrastucture was observed by electron microscopy. Serum free calcium concentration was measured by atomic absorption spectrophotometry. The activities of phosphorylas...

The intrathecal injection of fenvalerate, a sodium channel activator, at doses of 0.01 to 3 pg, dose-dependently induced the duration of a characteristic behavioral syndrome mainly consisting of reciprocal hind limb scratching directed towards caudal parts of the body and biting or licking of the hind legs in mice. Fenvalerate-induced behavior was inhibited by morphine ( I I O mg/kg, i.p.). The...

The influence of the commercial emulsifier on the acute toxicity and uptake of fenvalerate [(R,S)-αcyano-3-phenoxybenzyl(R,S)-2-(4-chlorophenyl)-3-methylbutyrate], a synthetic pyre-throid insecticide, by fathead minnows (Pimephales promelas) was examined. Flow-through acute toxicity testing with measured concentrations of technical-grade fenvalerate and a 30% active ingredient emulsifiable conc...

Aim: Evaluation of combined effect of fenvalerate and nitrate on biochemical parameters in buffalo calves. Materials and Methods: Sixteen male buffalo calves were divided into four groups of four calves each. Group I receiving no treatment served as the control. Group II and III animals were orally administered with fenvalerate (1.0 mg/kg/day) and sodium nitrate (20 mg/kg/day), respectively, fo...
