Results and discussion
Results of examinations
- Clinical signs:
- effects observed, non-treatment-related
- Description (incidence and severity):
- No clinical signs were observed at all the dose groups, except few male animals that showed signs of salivation at high dose group. These signs were considered to be treatment related, since they were persistent till the last day of dosing and increased number of cases were observed by the end of the treatment. However, in recovery period these signs were reversed and no cases were noted with salivation. In female animals, transient cases of salivation and rales were observed, which were not considered to be treatment related.
- Mortality:
- no mortality observed
- Description (incidence):
- No mortality was observed in all the main groups and satellite/recovery group.
- Body weight and weight changes:
- no effects observed
- Description (incidence and severity):
- No treatment related body weight changes were observed in both male and female rats during the course of administration of the test chemical. Also, normal body weight gain was observed in the animals of both the sexes in recovery group.
- Food consumption and compound intake (if feeding study):
- effects observed, treatment-related
- Description (incidence and severity):
- Food consumption was significantly and dose dependently decreased, when compared to the control group in both the sexes during the course of the treatment. This effect was reversed in the recovery period.
- Food efficiency:
- not examined
- Water consumption and compound intake (if drinking water study):
- not specified
- Ophthalmological findings:
- no effects observed
- Description (incidence and severity):
- No abnormal opthamological findings were observed in the test groups or recovery group, during and after the administration of the test chemical.
- Haematological findings:
- effects observed, treatment-related
- Description (incidence and severity):
- Hematological parameters such as PT, APTT, Differential leucocyte count, were affected due to the administration of the test chemical in both male and female animals. However, these effects were reversed during the recovery period.
- Clinical biochemistry findings:
- effects observed, treatment-related
- Description (incidence and severity):
- At high dose changes in vital liver enzyme levels (AST, ALT) were observed. Also there was change in serum Electrolytes and Glucose were observed. However, all these effects were reversed during the recovery period.
- Urinalysis findings:
- effects observed, treatment-related
- Description (incidence and severity):
- Changes in urine parameters were observed mainly in males were observed due to the administration of the test chemical. Parameters were observed to be normal and within the range in case of females.
- Behaviour (functional findings):
- no effects observed
- Description (incidence and severity):
- No effects were observed in behavioural parameters in both male and females in neurobehavioural and functional observational battery during the course of administration of the test chemical.
- Immunological findings:
- not specified
- Organ weight findings including organ / body weight ratios:
- effects observed, treatment-related
- Description (incidence and severity):
- Statistical significant difference in the weight of kidneys and thymus were observed in males and females due to the administration of the test chemical.
- Gross pathological findings:
- effects observed, treatment-related
- Description (incidence and severity):
- In the gross pathological parameters, the lumen of the cecum was observed to be dilatedin both male and female animals at high dose group. This effect was atributed to the administration of the test chemical. In recovery group males, one animal showed dilated renal pelvis in observation of kidneys, but this effect was not attributed to the administration of the test chemical. No other abnormal changes were observed in the females of recovery group.
- Neuropathological findings:
- not specified
- Histopathological findings: non-neoplastic:
- effects observed, non-treatment-related
- Description (incidence and severity):

- not specified
- Other effects:
- not specified

Applicant's summary and conclusion

- Executive summary:
A study was conducted to assess the toxicity of the test chemical after repeated exposure for 28 days. The study was conducted according to OECD test guideline 407. The doses used for the study were 0, 40, 200 and 1000 mg/kg bw. Two satellite groups were included in the study as control group recovery (0 mg/kg bw) and high dose recovery (1000 mg/kg bw). 6 animals per sex were used per group. The test chemical was dissolved in olive oil. The animals were dosed for 28 days and the effects observed were as follows. No clinical signs were observed at all the dose groups, except few male animals that showed signs of salivation at high dose group. These signs were considered to be treatment related, since they were persistent till the last day of dosing and increased number of cases were observed by the end of the treatment. However, in recovery period these signs were reversed and no cases were noted with salivation. In female animals, transient cases of salivation and rales were observed, which were not considered to be treatment related. No mortality was observed in all the main groups and satellite/recovery group. No treatment related body weight changes were observed in both male and female rats during the course of administration of the test chemical. Also, normal body weight gain was observed in the animals of both the sexes in recovery group. Food consumption was significantly and dose dependently decreased, when compared to the control group in both the sexes during the course of the treatment. This effect was reversed in the recovery period. No abnormal opthamological findings were observed in the test groups or recovery group, during and after the administration of the test chemical. Hematological parameters such as PT, APTT, Differential leucocyte count, were affected due to the administration of the test chemical in both male and female animals. However, these effects were reversed during the recovery period. At high dose changes in vital liver enzyme levels (AST, ALT) were observed. Also there was change in serum Electrolytes and Glucose were observed. However, all these effects were reversed during the recovery period. Changes in urine parameters were observed mainly in males were observed due to the administration of the test chemical. Parameters were observed to be normal and within the range in case of females. No effects were observed in behavioural parameters in both male and females in neurobehavioural and functional observational battery during the course of administration of the test chemical.
