[Toxicologic evaluation of propyneb on the Wistar rat].
This experiment was performed in Wistar rats of both sexes exposed subchronically to 1:100, 1:500, 1:1000 and 1:1500 LD50. The evaluation was based on endpoints measured on the 30th and 90th after starting exposure and after a recovery period of 30 days: these included clinical signs, functional changes, hematological parameters, urine analysis, biochemical, histochemical, immunomorphological endpoints, electron microscopy of internal organs, chromosome examination of bone marrow. A high lethality was shown to occur with a characteristic clinical picture: interruption of weight gain, behavioural changes, leucopenia mainly involving neutrophil leucocytes, biochemical changes characteristic of liver, cardio-vascular system (myocardium and aorta) together with pathologic, biochemical, histochemical and ultrastructural changes in liver, brain, thyroid gland, myocardium, spleen and bone marrow. Endpoints were shown to be clearly dose-dependently related with small variations with the low dose, i.e. 1:1500 LD50 (5 mg/kg-1 bw).
