Cypermethrin is a photostable synthetic pyrethroid and the most widely used Type II pyrethroid pesticide. The effects of two different stereoisomers of cypermethrin insecticides, alpha-cypermethrin and theta-cypermethrin, on the delayed rectifier potassium current (IK) in hippocampal neurons of rat, were studied using whole-cell patch clamp technique. Alpha-cypermethrin and theta-cypermethrin d...

We evaluated ameliorative effects of Jamun seed and orange peel extracts on liver toxicity in cypermethrin exposed rat. Methods: Rats were given following treatments daily for 30 d: Group A: Control Group B: Rats received cypermethrin Group C: These rats received cypermethrin and Jamun seed extract simultaneously Group D: These rats received cypermethrin and orange peel extract simultaneou...

Fresh water fish, Heteropneustes fossilis were subjected to 5.76 μg/L (0.8 of 96 h 50% lethal concentration, LC50) and 1.44 μg/L (0.2 of 96 h LC50) solution of cypermethrin for short-term (96 h) and long-term (28 days), respectively. After short-term cypermethrin exposure, the plasma calcium levels of Heteropneustes fossilis showed a decrease which persisted for 96 h. In long-term exposed fish,...

α-Cypermethrin is a widely used insecticide and, at high doses, induces oxidative stress in mammals. Curcumin is an antioxidant phytochemical commonly used for food coloring and flavoring. We aimed to investigate the effects of continuous dietary exposure to low doses of α-cypermethrin, as is the case in exposed humans, on oxidative stress and its potential prevention by dietary curcumin. Four ...

Background: Cypermethrin is an insecticide that is widely used in pest control programs. Previous studies have pointed out its harmful effects on the male reproductive system. Therefore, in the present study, vitamin E and selenium were used to protect the testicles from the damage of this poison. Materials and methods: For this study, 42 adult male Wistar rats were prepared and divided into 6...

INTRODUCTION Cypermethrin causes its neurotoxic effect through voltage-dependent sodium channels and integral protein ATPases in the neuronal membrane. Brain and nerve damage are often associated with low residual level of pesticides. In vitro and in vivo studies have also shown that pesticides cause free radical-mediated tissue damage in brain. Propolis has antioxidant properties. The main che...

Cypermethrin is one of the most highly effective synthetic pyrethroid insecticides. The toxicity of cypermethrin to the reproductive and nervous systems has been well studied. However, little is known about the toxic effect of cypermethrin on immune cells such as macrophages. Here, we investigated the cytotoxicity of cypermethrin on macrophages and the underlying molecular mechanisms. We found ...

Cypermethrin is a synthetic pyrethroid and pyrimethrin analogue. Cypermethrin poisoning produces neurological manifestations due to its primary target on sodium channels.1 Neuropathy following cypermethrin poisoning is common. But myelopathy is rare and not reported so far. We report a 17 year old healthy male who developed myelopathy following cypermethrin ingestion. The possible mechanism for...

In this study, freshwater fish Cyprinus carpio was exposed to sub lethal concentration of synthetic pyrethroids insecticide cypermethrin to evaluate the impact on nucleic acids in different organs. Fishes were exposed to sub lethal concentration (1/10th of LC50 value) of cypermethrin for three different durations, 7, 14 and 21 days. In seven day exposed fishes, DN...

A cypermethrin-degrading bacterium (SG4) was isolated from the pesticide-contaminated soil in the agricultural field of the crop research centre of the University, and characterized as Bacillus thuringiensis strain, SG4. The bacterium degraded 78.9 % of cypermethrin (50 ppm) in 15 days when grown in a minimal medium. To understand the functional proteins of cypermethrin degradation in Bacillus ...
