摘要

Trypanosoma brucei brucei, a haemo-protozoan parasite causes African Animal Trypanosomiasis (AAT). Khaya senegalensis (KS) and Anogeissus leiocarpus (AL) are medicinal plants used either individually or in combination by local farmers in Northern Nigeria in the treatment of many diseases including trypanosomiasis. There is however, no information on the efficacy of the plants used in combination. In this study, the antitrypanosomal activity of combined methanolic stem bark extracts of K. senegalensis and A. leiocarpus were determined in vivo using suppressive and repository tests. The combined extracts were administered at 250 mg/kg to T. b. brucei infected rats in ratios 1:4, 2:3, 1:1, 3:2 and 4:1 (K. senegalensis to A. leiocarpus). Diminor? (3.5 mg/kg) was positive control and Tween-80 the negative control. Trypanocidal activity was recorded in all four ratios with the highest in the 4:1 ratio for both tests. All ratios in repository test had varying levels of prophylactic activity which were significantly higher (p0.05) favorably with the positive control. The extracts however had significantly lower (p<0.05) parasite suppressive activity compared to Diminor? (100%). The 1:4 combinations had the lowest activity (4.35%). In the repository test, packed cell volume (PCV) levels varied in the groups with an increase as the quantity of K. senegalensis in the dose increased. The results therefore show that the antitrypanosomal activity and haemolytic effects of the extracts was dependent on the ratio of K. senegalensis to A. leiocarpus. A higher quantity of K. senegalensis provided a more effective prophylaxis and normal PCV. The use of a threefold quantity of K. senegalensis to A. leiocarpus in the local management of animal trypanosomiasis is therefore suggested.

(3.5 mg / kg)为阳性对照,而Tween-80为阴性对照。在所有四个比率中均记录了锥虫杀灭活性,两个试验中的比率均最高,为4:1。贮藏库测试中的所有比率均具有不同的预防活性水平,与阳性对照组相比,显着更高(p0.05)。然而,与Diminor?相比,提取物具有较低的(p <0.05)寄生虫抑制活性。 (100%)。 1:4组合的活性最低(4.35%)。在储存库测试中,随着剂量中塞内加尔K.senegalensis数量的增加,分组细胞体积(PCV)水平随组的增加而变化。因此,结果表明,提取物的抗胰蛋白酶活性和溶血作用取决于塞内加尔K.与Leocarpus的比例。大量的塞内加尔K. Senegalensis提供了更有效的预防和正常的PCV。因此,建议在动物锥虫病的局部管理中使用三倍量的塞内加尔羊角线虫到Leocarpus。
