Pesquisa Veterinaria Brasileira, 2016Co-Authors: Marina Paula Lorenzett, Paula Reis Pereira, Daniele Mariath Bassuino, Guilherme Konradt, Welden Panziera, Matheus Viezzer Bianchi, S P Pavarini, D DriemeierAbstract:Introducao: Trema micrantha e uma especie arborea pertencente a familia Cannabaceae, amplamente distribui- da no Brasil, com ocorrencia nas zonas tropicais e subtropicais na America do Sul, Central e do Norte (Lorenzi 2008). A planta e palatavel (Traverso et al. 2004) e suas folhas sao imediatamente consumidas por herbivoros, especialmente em tempos de escassez de alimentos (Wouters et al. 2013). O consumo de Trema micrantha na regiao Sul do Brasil, tem sido associado com intoxicacoes naturais em caprinos (Traverso et al. 2003, Gava et al. 2010), equideos (Bandarra et al. 2010, Pavarini et al. 2013) e ovinos (Wouters et al. 2013), e reproducoes experimentais demonstraram toxicidade para bovinos (Traverso et al. 2004) e coelhos(Traverso & Driemeier 2000). O quadro clinico-patologico observado na intoxicacao por Trema micrantha e caracterizado por insuϐiciencia hepatica aguda devido a necrose centrolobular de hepatocitos (Traverso et al. 2003) e por vezes associado a sinais neurologicos de encefalopatia hepatica (Bandarra et al. 2010, 2011, Pavarini et al. 2013). Em ovinos, alem de alteracoes hepaticas, observou-se o desenvolvimento de pneumopatia toxica induzida apos ingestao de sucessivas doses da planta (Wouters et al. 2013). Esse trabalho tem por objetivo relatar os aspectos epidemiologicos e clinico- -patologicos da intoxicacao natural por Trema micrantha em equinos, com enfase em alteracoes no encefalo.

Trema micrantha toxicity in horses in Brazil
Equine veterinary journal, 2010Co-Authors: Paulo Mota Bandarra, Andre Mendes Ribeiro Correa, S P Pavarini, Djeison Lutier Raymundo, Pedro Miguel Ocampos Pedroso, D DriemeierAbstract:Summary After ingesting green leaves of T. micrantha, 2 horses showed apathy, locomotor deficit, blindness, recumbency, paddling, coma and death. The main gross findings were scattered haemorrhages, enhanced lobular pattern of the liver, and cerebral oedema. Histological changes included disseminated haemorrhages, massive hepatocellular necrosis, neuronal degeneration, Alzheimer type II astrocytes and cerebral perivascular oedema. Clinicopathological findings which were comparable with those observed in Trema micrantha poisoned ruminants, associated with epidemiological evidence suggested the diagnosis.Trema micrantha poisoning should be evaluated as a possible cause in the diagnosis of equine hepatopathy and occasional secondary encephalopathy.

intoxicacao experimental por Trema micrantha ulmaceae em bovinos
Pesquisa Veterinaria Brasileira, 2004Co-Authors: S D Traverso, Andre Mendes Ribeiro Correa, Milene Schmitz, Edson Moleta Colodel, D DriemeierAbstract: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 T. micrantha. Clinical signs were observed in six goats that became ill 2 days after having been dosed with or fed the plant. There were five 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 coma were seen in one goat. T. 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.

Acute effect of Trema micrantha (Ulmaceae) on serum glucose levels in normal and diabetic rats
Journal of ethnopharmacology, 2006Co-Authors: Tatiana Schoenfelder, Thayse Marcon Cirimbelli, Vanilde Citadini-zanetteAbstract:Trema micrantha (Ulmaceae) ethanolic crude extract (ECE) was screened for its hypoglycemic activity (250, 500 and 1,000 mg/kg v.o.). The animals were divided in three groups for the evaluation of the hypoglycemic effect: normal rats, rats with alloxan-induced diabetes and hyperglycemic normal rats. The antihyperglycemic activity was compared to the treatment with glibenclamide, an oral hypoglycemic agent. Serum glucose was analyzed after the treatment of the animals. The acute treatment with Trema micrantha ECE (250 and 1,000 mg/kg) caused a significant decrease in the blood glucose levels in diabetic rats, but no effect was observed among the normal treated rats nor the hyperglycemic normal rats. Trema micrantha's leaves are a good candidate for alternative and/or complementary medicine in the management of diabetes mellitus, since they showed beneficial effects on blood glucose levels.

STUDY ON PRIMING METHODS TO ENHANCE THE VIABILITY AND VIGOR OF Trema (Trema orientalis LINN. BLUME) SEEDS
Indonesian Journal of Forestry Research, 2019Co-Authors: Naning Yuniarti, Rina Kurniaty, Dida SyamsuwidaAbstract:Trema is one of tropical forest trees that has many advantages such as wood for building, pulp and charcoal, leaves for medicine and bark for dye material. The constrain of the development of this species is the difficulties of the seeds to germinate and the rapid deterioration of the seeds after being stored. Therefore, there should be a right method to solve the problems. The aim of the study is to determine the proper method of priming to enhance the viability and vigor of Trema seeds after storage. Randomized Complete Design was employed in this trial by priming the seeds before and after storage. The treatments werepriming methods including: control (no priming), matriconditioning with ash, osmoconditioning by soaking of 5% H 2 O 2 , humidify with water and hydrated-dehydrated process. The observed parameters were thepercentages and speed of germination. The results showed that the treatment method of priming the best for this type of Trema, both before storage and after storage hydration is the treatment of dehydration. Before storage, can increase the value of germination percentage and speed of germination respectively 15% and 0.9% /Etmal. After the storage, treatment hydration dehydration can increase 17% germination and speed of germination of 1.25% / Etmal.

Pesquisa Veterinária Brasileira, 2002Co-Authors: Sandra Davi Traverso, Andre Mendes Ribeiro Correa, Edson Moleta Colodel, Claudio Estevao Farias Da Cruz, Caroline Argenta Pescador, David DriemeierAbstract: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.
