postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Inhalation carcinogenicity and chronic toxicity of indium-tin oxide in rats and mice.
OBJECTIVES Carcinogenicity and chronic toxicity of indium-tin oxide (ITO) were examined by inhalation exposure of rats and mice to ITO aerosol. METHODS Fifty mice of both sexes were exposed to ITO at 0 (control), 0.01, 0.03 or 0.1 mg/m(3) for 6 h/day, 5 day/wk for 104 wk, and 50 rats of both sexes were exposed to 0, 0.01 or 0.03 mg/m(3) ITO for the same time period. The repeated exposure of 5...
متن کاملCarcinogenicity and chronic toxicity after inhalation exposure of rats and mice to N,N-dimethylformamide.
Carcinogenicity and chronic toxicity of N,N-Dimethylformamide (DMF) were examined by inhalation exposure of groups of 50 rats and 50 mice of both sexes to DMF vapor at a concentration of 0, 200, 400 or 800 ppm (v/v) for 6 h/d, 5 d/wk, for 104 wk. In rats, incidences of hepatocellular adenomas and carcinomas significantly increased in the 400 and 800 ppm-exposed groups and in the 800 ppm-exposed...
متن کاملCarcinogenicity and toxicity of methoxychlor.
Methoxychlor is carcinogenic for the liver of C3H and BALB/c mice and Osborne-Mendel rats, and possibly for the liver of dogs. Methoxychlor is also carcinogenic for the testis of BALB/c male mice, bone of B6C3F1 female mice, and the ovary of Osborne-Mendel female rats. The incidences of carcinomas of the liver were increased in C3H male mice and BALB/c male and female mice fed methoxychlor. The...
متن کاملInhalation toxicity and carcinogenicity of 1,3-butadiene in Sprague-Dawley rats.
A 2-year inhalation study was conducted in Sprague-Dawley rats with 1,3-butadiene. Groups of 110 male and 110 female rats inhaled 1,3-butadiene at 0, 1000, or 8000 ppm for 6hr/day, 5 days/week. Interim clinical pathology, neuromuscular, and histopathology investigations were carried out. The study terminated at 20 to 25% survival (105 weeks for females, 111 weeks for males). Following exposure ...
