Abstract: Green leaves of Trema micrantha were ground and mixed with water in a domestic blender and then administered by stomach tube to seven goats. One additional goat was fed ad libidum with the green leaves of micrantha. Clinical SigAS were observed in six goats that became ill 2 days after having been dosed with or fed the plant. There were tive deaths, which occurred until 4 days after ingestion. Affected goats remained static during long periods and kept their heads low. Incoordination, rhythmical movements of the head, apathy, anorexia, and tenesmus were also noticed. paddling movements and com as were seen in one goat. r micrantha was toxic at dosages of 30 g/kg or higher. The most significant gross lesions were observed in the livers, which were yellowish, friable, and with pronounced lobular pattern. Their cut surfaces were reddened and depressed areas alternated with whitish ones. The liver of one goat was slightly but homogeneously reddened but did not show accentuated lobulation. Petechial haemorrhages in the region between the chest and scapula, in the epicardium, mediastinum and serosal membranes of the abdominal organs were also observed. The most important histologic finding was hepatic centrilobular coagulative necrosis, which was associated with congestion, haemorrhages and degenerative changes in the circumjacent hepatocytes. Additional microscopic lesions were found in the nervous system and included perineuronal and perivascular edema and swollen neurones, especially those of the frontal cortex.

Resumo: Sete caprinos receberam, por sonda esofágica, uma suspensão aquosa de folhas verdes de Trema micrantha moídas e um outro recebeu folhas verdes da planta à vontade. Os sinais clínicos iniciaram-se 2 dias após a ingestão e ocorreram em seis caprinos, cinco dos quais morreram em até 4 dias. Os animais doentes permaneciam longos períodos em estação, com cabeça baixa, olhar fixo, apáticos e inapetentes. Tenesmo, incoordenação e movimentos rítmicos laterais da cabeça também foram observados. T. micrantha mostrou-se tóxica a partir de 30g/kg de peso corporal. A alteração macroscópica mais significativa foi observada no fígado, que se apresentou friável, amarelado e com acentuado padrão lobular. Ao corte, havia áreas vermelhas, deprimidas e entremeadas por áreas mais claras. Em um animal, a coloração do fígado era vermelha, homogênea, mais clara que o normal e sem evidenciação do padrão lobular. Petéquias foram constatadas entre a escápula e o esterno, no epicárdio, no mediastino e nas serosas dos órgãos da cavidade abdominal. A principal alteração histológica foi necrose coagulativa centro-lobular que, em alguns casos, atingia todo o lóbulo, associada à congestão, hemorragia e alterações degenerativas nos hepatócitos circunjacentes. No sistema nervoso, havia tumefação de neurônios, mais proeminente no córtex frontal, associado a edema perineuronal e perivascular.
