Abstract
Disodium hemiphthalate Glycyrrhetinic acid (DHGA) possesses anti-inflammatory and analgestic activities. In our research, this agent was injected intraperitoneally to mice, according to the following schedule.
1) 25 mg/kg, 50mg/kg & 75mg/kg at 7th day of pregnancy.
2) 50 mg/kg & 75mg/kg at 8th day of pregnancy.
3) 50mg/kg & 75mg/kg at 9th day of pregnancy.
DHGA with doses of 50mg/kg and 75mg/kg at 7th, 8th and 9th day, delays the growth, decreases developing of ossification centers (specially in hand and foot middle phalanxes), decreases the number of caudal vertebrae of sacro-illiac joint and results in slight but important increases in fetus mortality.

Abstract
Gentamicin was evaluated for developmental toxicity in pregnant Sprague-Dawley rat. Gentamicin was administered subcutaneously on days 6-15 gestation at dose of 100 mg/kg. On gestation day 21, all live fetuses were examined for external and skeletal malformations and variations. Increased resorptions and dead fetuses, and reduced fetal body weight were observed at dose of 100 mg/kg. Gentamicin caused severe skeletal anomalies, such as: wavy ribs, incomplete ossification of sternebrae, tail vertebra, metacarpus, metatarsus and calvaria. These results indicate the nature and extent of embryotoxicity and teratogenicity of gentamicin in Sprague-Dawley rats.
