Cytological effects of some organophosphorus pesticides. II Meiotic effects.

Evaluation of the effects of chronic exposure to organophosphorus pesticides on thyroid function

Biochemical effects of some organophosphorus pesticides on the ovaries of albino rats.

An evaluation of the toxic effects of three organophosphates; monocrotophos, dimethoate and methyl parathion on female reproduction was made by biochemical estimations of cytoplasmic and membrance bound proteins, lipids, phospholipids and cholesterol in the rat ovaries after treatment with their low residual level doses (LD50 1/8-1/5) to three groups of six rats each for 90 days. All the three ...

Enzymatic changes induced by some organophosphorus pesticides in female rats.

An evaluation of toxic effects of three organophosphorus pesticides viz. monocrotophos, methyl parathion and dimethoate given orally daily for 90 days was done in terms of enzymatic changes in plasma and liver of female albino rats. A significant decrease was observed in the level of esterases in plasma with all the three pesticides. The activity of acid and alkaline phosphatases and aminotrans...

Cytological effects of infection with T5 and some related phages.

Luria and Human (1950) reported the cytological effects on Escherichia coli, strain B, of infection with the T-phages, excepting T5. This provided a more detailed description of the effects already noted by Luria and Palmer (1946) and by Delaporte (1948) who used T4. A study of T2r and T2r+ (Murray et al., 1950) provided little additional information. The observed changes were distinct for each...

Effects of Pesticides on Male Reproductive Functions

Exposure to pesticides could be one of the contributing cause to the falling sperm counts and rising levels of male infertility. Adverse effects of pesticides in the environment first received widespread attention in the 1960s. However, only recently it has been postulated that long term, low exposure of these chemicals are increasingly linked to human health effects such as immuno-suppression,...
