Histopathological Changes in Liver and Kidney of Common Carp Exposed to Sub-lethal Doses of Malathion
The present study was conducted to evaluate the effects of an organophosphorous pesticide malathion on histo-architecture of liver and kidney of common carp exposed to two sub-lethal concentrations (1.5 and 3.0 mg/L) for a period of 8 days. The 96 h LC50 value of malathion for common carp was 15.24 mg/L. Several morphological changes were observed in the liver after exposure to the malathion. H...
متن کاملHistopathological Changes of Zebrafish (Danio rerio) Ovaries Exposed to Sub-lethal Concentrations of Methyl Paraben
Paraben compounds are used widely as preservatives to inhibit microbial growth and extend used in pharmaceuticals, hygienic, cosmetics, care products. They pose the potential for reproductive toxicity for users. This paper provides an overview of the applications of histopathological biomarkers in reproductive toxicity in zebrafish caused by methylparaben. The present study investigated the cha...
متن کاملHematological changes in Tinca tinca after exposure to lethal and sublethal doses of Mercury, Cadmium and Lead
Tench, Tinca tinca, were exposed to three treatments (one acute lethal 96 hrs Lc50/48 hrs and two chronic sublethal 10 and 25% Lc50/504 hrs) each of Mercury, Cadmium and Lead and its behaviour as an indicator of impaired hematology was studied. It was observed that impairments in hematological parameters (increased/decreased Hct, Hb, RBC, WBC and Lct) were reflected in behaviour of fish in the ...

متن کاملEffects of Sub-lethal Doses of Urea on Pregnant Cattle
Six pregnant cows received, by injection into the rumen, 0.20 to 0.30 g urea/kg body-weight at 104 to 148 days of pregnancy, 0.35 g/kg at 124 to 169 days of pregnancy, 0.35 g/kg at 208 to 226 days of pregnancy and 0.30 g/kg at 256 to 273 days of pregnancy. The change in blood ammonia concentration was followed for approximately seven hours after dosing. Five cows survived until calving and gave...
