Toxicological Effects of Organophosphates Pesticides

Toxicological studies of pesticides on cytoplasmic streaming in Nitella.

In the present study, changes in velocity of cytoplasmic streaming in the giant internodal cells of Nitella for varying concentration of the pesticides, 2,4-D, dieldrin, malathion, methyl parathion and endosulfan, were measured. Marked decrease in the velocity of cytoplasmic streaming was found at the concentrations of 0.01, 0.1, 1, 10 and 100mM. Dieldrin was the most toxic to all the pesticide...

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,...

Review of the Pharmacological and Toxicological Effects of Salvia leriifolia

Salvia leriifolia Benth. (vernacular names such as Nuruozak and Jobleh) is a perennial herbaceous plant that grows exclusively in south and tropical regions of Khorasan and Semnan provinces, I. R. Iran. Unlike other species of Salvia genus, the chemical constituents of S. leriifolia are not well recognized. The stem oil of the plant consisted mainly both monoterpenes and sesquiterpenes, while i...

Adverse health effects after low level exposure to organophosphates.

Acute poisoning with organophosphate based pesticides is a notable cause of morbidity and mortality in the developing world, but much less common in the United Kingdom. However, the potential for frequent low level exposures to organophosphates exists for many occupational groups including agricultural workers, sheep dippers, and pesticide sprayers. Over the past decade an increasing number of ...
