Senna Alata

This study was aimed at determining the effect of leaves of Senna alata extract on biochemical indices of Wistar rats infected with Trypanosoma brucei brucei. Phytochemical screening revealed the absence of steroids in all extracts, absence of saponins in chloroform extracts and the presence of free anthraquinones only in chloroform extract. Post-infection treatment of animals stirred the emergence of parasitaemia by Day 3. Only animals receiving 200 mg/kg b.wt. of chloroform extract survived by day 16. A significant (P<0.05) decrease in ALT for groups receiving methanol (400 mg/kg b.wt.), chloroform and aqueous extracts and significant (P<0.05) increase in unconjugated bilirubin in the group receiving methanol extract (200 mg/kg b.wt.) compared to infected not treated rats. Significant (P<0.05) decrease in potassium concentration in groups receiving methanol and chloroform, and a significant (P<0.05) increase in sodium concentration in the group receiving 400 mg/kg b.wt. of aqueous extract compared to the infected not treated rats. These results thereby demonstrate the ameliorative potential of Senna alata leaves against T. brucei brucei.

This study determined haematological changes in Wistar rats experimentally infected with local strains of Trypanosoma congolense and Trypanosoma brucei brucei. Forty-five Wistar rats between 10 – 12 weeks old weighing between 210 – 240 g were used. The Wistar rats were randomly divided into four groups (A, B, C and D), with the infected groups (B, C and D) having 10 rats each, while the uninfected control group (A) had 15 rats. Group A rats were not infected and served as the control, group B were infected with Trypanosoma congolense, group C were infected with Trypanosoma brucei brucei and group D were co-infected with Trypanosoma congolense and Trypanosoma brucei brucei. Infection was achieved using 0.1mL of blood containing approximately 1 × 103 trypanosomes intraperitoneally into each Wistar rat in the infected groups. Clinical signs were observed. The changes in the blood cells were assayed in the groups post-infection. Duncan’s Least Square Deviation showed significantly (p<0.05) higher parasitaemia in infected groups. However, group D showed a higher significant (p<0.05) difference in parasitaemia when compared to groups B and C. The pattern of mean parasitaemia for the infected groups, revealed a positive correlation with days of post-infection (p<0.05) before the decline. The packed cell volume, total red blood cell count and haemoglobin concentration were significantly (p<0.05) lower in infected groups B, C and D. The total white blood cell count, platelet counts and differential leucocyte count were significantly (p<0.05) lower in infected groups when compared to the uninfected group. These findings suggest that co-infection with Trypanosoma congolense and Trypanosoma brucei brucei obtained from Wurno and Ngaski in Sokoto and Kebbi States respectively produced a more damaging effect on haematological parameters.

This study evaluated in vitro and in vivo antitrypanosomal effect of artesunate and/or diminazene aceturate in Wistar rats experimentally  infected with Trypanosoma brucei brucei. In vitro screening was carried out in triplicates using 50 μl of 0.2, 2 and 20 μg/μl of artesunate as test drug; diminazene aceturate, normal saline and trypanosome-infected blood served as controls in a 96-well microtitre plate, incubated at 37˚C for 5 minutes. Efficacy was observed over a period of 60 minutes for reduced or complete trypanosomal immobilization. Results showed concentration-dependent cessation of trypanosomal motility was significantly (p < 0.001) induced by artesunate when compared to the controls. Seventy Wistar rats of both sexes weighing between 190 and 210 g were randomly divided into 7 groups (5 males and 5 females) are used for in vivo study. Groups I and II served as normal control and model control respectively. Groups III to VII were infected with Trypanosoma brucei brucei (106 trypanosomes/ml) intraperitoneally. At peak parasitaemia (8 days post-infection), group III was treated with diminazene aceturate (3.5 mg/kg) intramuscularly once while groups IV, V, VI were treated with artesunate (200, 100, 50) mg/kg orally for 5 consecutive days and group VII was treated with combination of artesunate (50 mg/kg) orally and diminazene aceturate (1.75 mg/kg) intramuscularly for 5 days. Results indicated pre-patent period of 4 days and increase in levels of parasitaemia post-inoculation. PCV, Hb concentration, RBC count, MCV, MCHC and total leucocyte count decreased significantly (p < 0.05) between days 0and 8 in groups II to VII. Following treatment, significant increases (p < 0.05) were recorded except for groups II, IV, V and VI where the rats died. Thus, combination of artesunate (50 mg/kg) and half the standard dose of diminazene aceturate was able to reduce parasitaemia and ameliorate the anaemia elicited by the trypanosomes.
