Histological and biochemical study of liver of silver carp (Hypophthalmichthys molitrix) after acute exposure to pyrethoride (deltamethrin)

...xic as compared to organochlorine and organo-phosphate pesticides. Deltamethrin was selected to study the biochemical and histological
alterations in liver of silver carp. The LC50 1.6 μg/L was determined. Fish (n=6) were dividing into 4 groups A (control)
B, C and D (experimental). Experimental groups B, C and D were exposed to 25%, 50% and 75% of LC50
respectively for acute exposure. The blood and liver tissue sampling was done after ...

...ects of mixture of organochlorine (endosulfan) and organophosphate (chlorpyrifos) investigated on the activity of antioxidant enzymes viz. superoxide dismutase, peroxidase, catalase and glutathione S-transferase in different organs (liver, gills, kidney, brain, heart and muscle) of fish, Labeo rohita. The LC₅₀ of chlorpyrifos+endosulfan mixture was calculated as 1.95±0.02 μgL^-1 for 96 h with the 95% confidence limits. The...

Development and Laboratory Evaluation of a Slow Release Formulation of Fipronil against Subterranean Termites (Odontotermes obesus Rambur)

...te pests including organochlorines, organophosphates and pyrethroids. However, pesticidal control of termites is usually not persistent and long-lasting due to rapid decomposition and loss of insecticidal molecules active against target pests. This study was aimed to develop and evaluate a slow-release formulation (SRF) of a persistent insecticide (fipronil) against O. obesus. Technical grade insecticide fipronil was applied in the form of cellulose-made pelle...

...bendazole) and negative (chlorine-free water) control groups in vitro. Microscopic examination of the treated Fasciola spp. eggs with ginger methanolic extract revealed that the various concentrations of Z. officinale methanolic extract used in our study were highly sensitive to it and that their activities differed noticeably from those of the positive (albendazole) and negative (chlorine-free water) controls. The ovacidal ...

The results showed that after 30 minutes of treatment with 200, 100, or 50 ppm chlorine, the numbers of culturable E. coli significance P<0.05 dropped (100%) from 6.93±0.04 log10 CFU/mL to less than 1 CFU/mL (0.0%). However, after 48 hours of resuscitation using sodium pyruvate as nouris...
