  • To evaluate the modifying effect of Kwao Kreu, Pueraria mirifica (PM) well-known as a rejuvenating folk medicine from Thailand, peri- and post-natal studies were carried out in rats. PM extract was administered to pregnant Sprague Dawley (SD) rats by oral gavage from gestation 6 (GD 6) to postnatal day 21 (PND 21). The amount of administered in this study was 0.042, 0.42 and 4.2 mg/kg/day, respectively. There were no treatment related changes of dams in deaths, clinical signs, and parturition. Treatment related changes in body weight, food consumption and lactation of dams were not observed. F1 fetuses in external abnormality, physical development, reflex/sensory functions and behavioral development were not found. No adults and F1 fetuses in organ weight was found with the exception of vagina and uterus of F1 fetuses. The results showed that PM extract, up to 4.2 mg, had no adverse effects on the peri- and post-natal development of rats. Therefore, PM extract has no adverse effects on peri- and post-natal development of rats.

  • A Peri-and Postnatal Study was Carried out to examine the effects of rHuIFN-${\alpha}A$, produced by gene-manipulated E. coli, on offsprings of Wistar rats. The substance was administered intraperitoneally to dams at dose levels of $1{\times}10^5$, $4{\times}10^5$ and $1.2{\times}10^6$ I.U/kg/day during the period from day 17 of gestation to day 21 after delivery. All the pregnant dams were allowed to deliver naturally, and the postnatal development of the offsprings was observed. No noticeable toxic effects and pathological changes on dams were observed, and no detectable variations in postnatal development of offsprings occured.
