After 30 days, pods of S. fissuratum ( Fig. 1) were collected and fed to the goats, as shown in Table 1. Goats that died after the consumption of the S. fissuratum pods were necropsied. During the necropsy, organs of the abdominal and thoracic cavities, and central nervous system were obtained and fixed in 10% buffered formalin, processed using the standard histological methods and stained with hematoxylin-eosin (HE). The legal and ethical requirements of the Animal Care Committee of the Federal University of Mato Grosso were followed in these experiments. The results of the experiments are presented see more in Table 1. Goats 1 and 2, which received

3 daily doses of 2.5 g/kg over the course of 3 days, showed clinical signs of poisoning beginning on the third day, aborted on days 14 and 8, and died on days 20 and 10, respectively. Goats 3 and 4, which received 2 daily doses of 3.25 g/kg over 2 consecutive days, showed clinical signs on the second day after administration and aborted on days 14 and 15. After the abortion, the goats recovered in 37 and 39 days respectively. The clinical signs observed in goats 1 and 2 consisted of marked

apathy, anorexia, ruminal hypomotility, engorged episcleral vessels, congested mucous membranes, jaundice, tearing of FRAX597 the eyes, abdominal cramps, and stools with yellowish mucus. After day 14, the signs progressed to ataxia, weakness, and lateral recumbency, followed

by death on day 20. Goat 2 also showed placental retention and died on day 10. Goats 3 and 4, which received 2 daily doses of 3.25 g/kg over the course of 2 days, showed clinical signs that were similar to, but less pronounced than those of goats 1 and 2 and fully recovered on day 37 after ingestion. Goats 5 and 6, which each received a single dose of 5.5 g/kg, showed mild transient anorexia, engorged episcleral vessels and ruminal hypomotility, and spent more time lying down than normal. These goats did not abort and recovered on days 12 and 14 after ingestion. Goats 7 and 8, each of which received a single dose of 5.0 g/kg, showed no Methamphetamine signs of poisoning and did not abort (Table 1). On necropsy of goats 1 and 2, the main findings consisted of mild jaundice, dry rumen contents including seeds of S. fissuratum, reddening of the ruminal mucosa, edema and ulceration of folds of the abomasum, and hemorrhage and hyperemia of the small intestinal mucosa. The contents of the small intestine were sparse and contained mucus. The liver was enlarged, reddish-brown, and had a pronounced lobular pattern. In goat 2, the uterus was enlarged, with congestion of the vessels on the serosal surface, friable mucosa and caruncles; it also contained a significant amount of black, hemorrhagic, foul-smelling material.
