Abstract
In the current study, to support the safety assessment of ethanamizuril as a new potent anticoccidial agent of triazine compounds, a reproductive toxicity and teratogenic potential assay of ethanamizuril was investigated. Groups of 30 males and 30 females were administered 0, 0.02, 0.1 or 0.2 mg/ml ethanamizuril by gastric incubation through a 10-week prebreed period as well as during mating, gestation, parturition and lactation in any generation. Compared to the control group, no test compound-related changes in copulation index, fertility index, gestation length, litter size, pup weight, pup sex ratio, pup viability, epididymal sperm counts or motility or other functional reproductive measures were noted in any generation, except few significant changes in high dose group in the number of sperm motility at III level in F0 males and the body weights of GD14 and GD21 in F1 rats. There were no compound-related necropsy findings or effects on organ weight. Histopathologic examinations revealed no evidence of compound-related changes in any organs including the reproductive organs of both sexes. In conclusion, long-term administrated 0.2, 1.0 and 2.0 mg/kg of ethanamizuril by means of oral gavage did not affect the reproduction of Sprague-Dawley rats and the development ability of their offspring under the experimental conditions.

Embryotoxic and teratogenic effects of norfloxacin in pregnant female albino rats. Adv Pharmacol Sci 2014; 2014:924706. [PMID: 24639869 PMCID: PMC3930024 DOI: 10.1155/2014/924706] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2013] [Revised: 12/13/2013] [Accepted: 12/13/2013] [Indexed: 11/17/2022] Open
Abstract
This study was designed to investigate the possible developmental teratogenicity of norfloxacin in rats. Forty pregnant female rats were divided into four equal groups. Group A received norfloxacin in a dose of 500 mg/kg·b·wt/day orally from 6th to 15th day of gestation. Groups B and C received 1000 and 2000 mg/kg·b·wt/day orally for the same period, respectively; Group D behaved as control and received 0.5 mL distilled water orally for the same period. The dams were killed on 20th day of gestation and their fetuses were subjected to morphological, visceral, and skeletal examinations. Norfloxacin significantly decreased the number of viable fetuses, increased the number of resorbed fetuses, and induced retardation in growth of viable fetuses; some visceral and skeletal defects in these fetuses were seen and these effects were dose dependant. Conclusively, norfloxacin caused some fetal defects and abnormalities, so it is advisable to avoid using this drug during pregnancy.

Abstract
Maternal food restriction (FR) may have strong and long-term effects on body weight, brain and behavior development of offspring. However, it is still not well understood whether such an effect is carried over to the next generation. Our objective was to examine the differences of maternal behavior, body growth, cranial growth and early development of F1 and F2 offspring of rat-like hamsters between a FR group and a control group. Results show that FR has a significant influence on maternal gathering behavior. The body weight of F1 offspring was significantly lower in the food-restricted group compared with that of the control animals, while the body weight of food-restricted F2 offspring was not significantly different from that of the control group. The physical development and neurodevelopment of food-restricted F1 and F2 offspring were significantly delayed compared to the controls. These results suggest that FR in female rat-like hamsters affected negatively the body growth of F1 offspring, and the physical and neurodevelopment of both F1 and F2 offspring. The effect of maternal FR on F2 offspring was smaller than that on F1 offspring. These factors may, in turn, play an important role in the population regulation of this species.
