The aim of the study was to evaluate the neurotoxic effect of a dermally-applied mixture of chlorpyrifos and cypermethrin in rats based on cognitive function, activity of the blood cholinesterase and brain acetylcholinesterase, as well as histologic brain examination. Nurelle D 550 EC (500 g of chlorpyrifos and 50 g of cypermethrin) was used in the study.(More)
The aim of the study was to assess the general toxic effects of dermally applied carbaryl, based on histological and ultrastructural examinations of internal organs and to relate these effects to earlier own studies where 14C carbaryl was used for determining the pesticide penetration. The pesticide was applied in doses of 1/5 and 1/10 LD50, administered to(More)
Nurelle D 550 EC preparation (Dow Elanco, USA) was applied in the study. The contents of biologically active substances in 1l of the preparation was: 500 g chlorpyrifos and 50 g of cypermethrin. The experimental studies were conducted on 4 groups of rats (2 control - 10 animals in each group, and 2 experimental - 40 animals in each group). The experimental(More)
The aim of study was evaluation of the concentration of dermally applied (14)C DDT in the organs of rats, and evaluation of histological and ultrastructural changes after the dermal application of unlabelled DDT standard in the organs of rats, in which the presence of this pesticide was determined by the radio-isotopic method. (14)C DDT of radiochemical(More)
The level of (14)C carbaryl was determined in blood (leukocytes, erythrocytes, all blood cells, plasma) and organs (brain, heart, lungs, liver, spleen, skin at the site of exposure) of male Wistar rats after dermal administration. The application liquid was (14)C carbaryl solution in 96% ethyl alcohol. This preparation, possessing an activity of 670 kBq/ml,(More)
