- CLINICAL SIGNS AND MORTALITY
No treatment-related effects were observed.
BODY WEIGHT AND WEIGHT GAIN
Treated males gained slightly less weight than the controls (800 mg/kg bw: 7%, 2000 mg/kg bw: 10%). As the difference is low, the decrease in body weight was not interpreted as a sign for systemic toxicity.
HAEMATOLOGY
No adverse effects on any haematologic parameters measured were observed.
CLINICAL CHEMISTRY
A few of the serum paramters of the high-dose animals were statistically different from the controls, but the differences were small, not consistent between males and females, and did not present any pattern suggestive of effects on any specific organ (no corresponding histological findings). Thus, the effects were considered not to be of toxicological relevance.
- high-dose males (compared to controls): glucose: -14%, albumin: -3%, and phoshorus: +16%
- high-dose females (compared to controls): lactate dehydrogenase: +45% (low-dose: +22%), and aspartate aminotransferase: +22%
URINALYSIS
No additional data given on Urinalysis in study report.
ORGAN WEIGHTS
Increased thyroid weight in the low-dose (+ 25%) females and decreased spleen weight (- 10%) in the low-dose males were not considered to be toxicologically relevant, as these effects were not observed in the high-dose groups.
GROSS PATHOLOGY
No abnormalities were detected.
HISTOPATHOLOGY:
No abnormalities were detected.
OTHER FINDINGS
- Sperm morphology: No effects on sperm morphology were detected.
- Local effects: Slight erythema and flaking of the skin were observed in the treated groups during the dosing phase. Microscopic examination of the skin indicated trace to slight epidermal hyperplasia and chronic inflammation of the superficial dermis.
SKIN PENETRATION
Skin penetration values of 2 - 6% were obtained.
The results of the in vivo skin penetration study indicate that the 13-week treatment with the test substance does not increase the skin penetration of the test substance (only the value for females was statistically different from the penetration in untreated animals). The skin penetration of untreated rats was less than 2% and the mean value for treated rats was approx. 6%. The recovery of radioactivity was measuered in the urine and faeces as well as the remaining radioactivity in tissue samples.
