“…This may indicate some mildly toxic effects of the extract at high doses. The mucus weight was increased compared with the control by both extracts, but this time the higher doses were more effective, in a manner comparable to that of the control (sucralfate), with the methanol extract being slightly more potent, these results are in agreement with earlier reports (Nwafor and Okwuasaba, 2001 Values indicated as mean SEM, n = 6 animals in each group (p < 0.05). Values indicated as mean SEM, n = 6 animals in each group (p < 0.05).…”

“…Once again, the aqueous extract was more effective than the methanol extract at reducing the area of ulcer lesion, and comparable to that of sucralfate, and again the higher concentrations were less effective at reducing the size of the lesions. The mucus weight was increased compared with the control only by the methanol extract, unlike sucralfate (which, as for the aqueous extract, produced little or no increase in mucus weight), but in this case the higher doses were more effective, as reported by Nwafor and Okwuasaba (2001).…”

“…The effects on intestinal propulsion in unanaesthetized rats were tested using charcoal method of Capasso et al (1976) and Nwafor and Okwuasaba (2001). Animals were fasted for 24 h but allowed free access to water.…”

“…As folhas e raízes de C. nigricans, muito comuns na medicina tradicional nigeriana, são indicadas para tratamento de úlceras gás-tricas 23 , disfunções gastrointestinais, dor reumatóide e como contraceptivo 24 ; no Senegal e na Guinea Francesa é utilizada como vermífugo 23 (Tabelas 1 e 2). Entretanto, não há relatos na literatura que validem tais atividades, o que estimulou Nwafor e Okwuasaba 24 a investigarem o extrato das folhas quanto à atividade antidiarrêica e anti-ulcerogênica.…”

“…Modelos farmacológicos baseados na indução de lesão gástrica por etanol e indometacina revelaram a capacidade do extrato em reverter tal lesão de modo dose-dependente, aparentemente por mobilização de prostaglandinas na mucosa gás-trica. Por outro lado, os resultados obtidos em vários experimentos sugerem que o extrato estudado é capaz de atuar como inibidor das funções gastrointestinais, mobilidade e secreção, efeito que pode ser relacionado à ativação do sistema α 2 -adrenoceptor e pode resultar no controle da diarréia 24 . A análise fitoquímica do extrato das folhas de C. nigrigans revelou a presença de taninos, saponinas e flavonóides, substâncias conhecidas por afetarem a integridade de membranas 21 .…”
