摘要
To determine the teratogenic effect of Mimosa tenuiflora, the green fresh plant was administered ad libitum to 12 goats (Group聽1) from day聽1 to day聽30 of gestation. Upon ultrasonographic examination, on day聽30, not one of these goats was pregnant, demonstrating that M. tenuiflora causes embryonic death. Six goats (Group聽2) ingested M. tenuiflora from day聽30 to day聽60 of pregnancy. Four goats delivered seven healthy kids and two were not pregnant based on ultrasonographic examination on day聽45 suggesting late embryonic death. Three other groups of six goats each received the plant on days 60-90 (Group聽3), 90-120 (Group聽4), and 120-150 (Group聽5) of gestation and a control group (Group聽6) all delivered normal kids, except one goat in Group聽4 that aborted and one adult goat from Group聽5 that was found dead. It is concluded that M. tenuiflora causes embryonic death. The failure to induce malformations might have resulted from a high dose of an unknown active principle of the plant causing fetal death.
