HISTOPATHOLOGY / ORGAN WEIGHTS: The tissues of all the rats were examined macroscopically at the time of sacrifice. The viscera
were removed and the liver, kidneys, spleen, heart, and testes were weighed. These organs, the remaining abdominal and thoracic viscera, and one hind leg, for bone, bone marrow, and muscle, were preserved in 10% buffered formalin-saline solution for histopathological examination. For routine histopathology, sections were embedded in paraffin wax and stained with haematoxylin and eosin. Tissues from rats dying during the experiment were examined for gross changes and were preserved if autolysis was not advanced. Organs were not weighed but abnormalities and the suspected reason for death were noted. - Postmortem examinations (offspring):

Applicant's summary and conclusion
- Conclusions:
- No Observed Adverse Effect Level (NOAEL) for reproductive toxicity was considered to 500mg/kg/day, When male and female Osborne-Mendel rats were treated with test chemical orally for 17weeks.
- Executive summary:
The reproductive toxicity of the test chemical was considered on the basis of repeated dose toxicity study.Groups of 10 male and 10 female Osbourne-Mendel rats were provided test chemical mixed in the diet at concentrations of 0, 1000, 2500 or 10,000 ppm which corresponding to an average daily intakes of 0, 50, 250, or 500 mg/kg bw per for 17 weeks. The animal’s weight, food intake and general condition were recorded every week. Haematological examinations were made at termination of the subacute studies. These examinations included white cell counts, red cell counts, haemoglobins and haematocrits. At the termination of the experiments the rats were sacrificed and exsanguinated. The tissues of all the rats were examined macroscopically at the time of sacrifice. The viscera were removed and the liver, kidneys, spleen, heart, and testes were weighed. These organs, the remaining abdominal and thoracic viscera, and one hind leg, for bone, bone marrow, and muscle, were preserved in 10% buffered formalin-saline solution for histopathological examination. For routine histopathology, sections were embedded in paraffin wax and stained with haematoxylin and eosin. Measurement of body weight and food intake recorded weekly showed no significant difference between test and control animals at any intake level. At termination, hematological examinations revealed no effects due to administration of the test chemical. At necropsy, no differences were reported in major organ weights between test and control animals. Gross examination of tissue of all animals was unremarkable and histopathological examination of six-eight animals, equally represented by gender, for the high-dose group and the control group revealed no treatment-related lesions. Hence, the highest dose tested i.e 500 mg/kg/day can be considered as the NOAEL
