RESUMO

Traditional medicinal plants are widely used as immunomodulatory medicines that help improve health. A total of 50 plants used for the treatment of toxicity were screened for their protective effects. Traditional medicinal are globally used and have rapidly grown in economic importance. Intrinsically active compounds are well-known for their antioxidant, anti-tumor, anti-viral, and anti-inflammatory activities. The study was conducted to investigate the effects of the ethanolic extract of C. arabica leaves on sexual behavior in Wistar rats. C. arabica, a medicinal plant with a foul odor, toxic, and hash allucinogenic effects. The experimental study was carried out on white rats (male and female) of the Wistar strain from the Pasteur Institute of Algiers (Kouba, Algeria), weighing between 150 and 200g sexually naive. The animals were raised in polyethylene cages and divided into two groups (n = 10 rats/group), which received a saline solution (male and female control group), 0.20µg/ml of the ethanolic extract of C. arabica leaves for seven days orally (male and female treated group). The sexual behavior test was performed according to three types of crossing. The results of the treated groups showed a significant increase in mating frequency compared to the control group. Overall, the results showed that C. arabica significantly affects sexual behavior. The ethanolic extract of C. arabica increased sexual behavior and orientation activity performance recorded in the treated animals. Thus, this study found that C. arabica has a significant effect on the rats' sexual behavior.

The study was conducted to investigate the effects of the ethanolic extract of C. arabica leaves on sexual behavior in Wistar rats. C. arabica, a medicinal plant with a foul odor, toxic, and has hallucinogenic effects. The experimental study was carried out on white rats (male and female) of the Wistar strain from the Pasteur Institute of Algiers (Kouba, Algeria), weighing between 150 and 200g sexually naive. The animals were raised in polyethylene cages and divided into two groups (n = 10 rats/group), which received a saline solution (male and female control group), 0.20µg/ml of the ethanolic extract of C. arabica leaves for seven days orally (male and female treated group).

RESUMO

Two goats which were housed and fed forages and commercial concentrate, died one week after being fed a mixture of plants. Amongst these plant was identified Trema micrantha. Only one animal was necropsied, and paleness of the carcass, subcutaneous haemorrhages in the region of chest and scapula, a yellowish and pliable liver with enhanced lobular pattern were the principal macroscopic findings. Additionally, in the cut surface from the liver, there were reddened and depressed areas mixed with withish ones. The most important histologic findings were hepatic centrilobular necrosis and haemorrhages associated with vacuolization of the periportal hepatocytes. In the encephalic tissue, there were vacuolisation, degeneration and necrosis of the neurones from cortex and hipocampus. The evidences of consumption of the plant and the hepatic lesions here described are consistent findings with the diagnosis of spontaneous poisoning by Trema micrantha.

Dois caprinos confinados, que recebiam ração e pasto no cocho, morreram uma semana após serem alimentados com arbustos de plantas de diferentes espécies, entre os quais encontrava-se Trema micrantha. Apenas um animal foi necropsiado. Achados macroscópicos incluíram palidez generalizada da carcaça, hemorragias subcutâneas na região do esterno e escápula, fígado amarelado, friável e com lobulação evidente. Na superfície de corte, o fígado apresentou áreas vermelhas deprimidas entremeadas por áreas claras, deixando na faca, restos de conteúdo amarelado de aspecto gorduroso. Histologicamente, observou-se necrose hepática centrolobular com hemorragia, associada à vacuolização de hepatócitos da região periportal. No encéfalo, havia vacuolização, degeneração e necrose de neurônios do córtex e hipocampo. Os indícios de ingestão da planta associado às lesões hepáticas descritas são compatíveis com intoxicação por Trema micrantha.
