A Teratological Study of Sprague-Dawley Rats with 3 (or 8)-(l-Methoxyethyl)-8 (or 3)-hydroxyethyl-deuteroporphyrin / 第二军医大学学报

ABSTRACT

The potential embryotoxicity, developmental toxicity and teratogenic effects of (3 or 8)-(l-methoxyethyl)-8 (or3)-hydroxyethyl-deuteroporphyrin (PsD-044) were investigated in Sprague-Dawley rats with the conventional teratological method in vivo. According to the recommending clinical dosage, PsD-044 was administered intravenously at 20, 10 and 5mg/kg, as compared to the negative control with saline and the positive control with sodium pentachlorophenolate, respectively on the 10th day of the gestation. Eighty-one pregnant rats and 803 fetuses were examined. The results suggest that the maternal toxicity, embryotoxicity and teratogenic effects of PsD-044 were not found, however, the malformation induced by known teratogen was as high as 14.1%.
