Strychnos Spinosa

The emergence of trypanocidal resistance has led to a change in the behavior and use of local plants for the treatment of parasites. The trypanocidal activity of Strychnos spinosa aqueous and ethanolic extracts on Trypanosoma brucei brucei was evaluated during ten days of treatment. Thus, the smear was used to monitor the parasitaemia of mice treated with Strychnos spinose aqueous and ethanolic extracts by gavage at doses of 250, 500, 1000 mg/kg (test groups); with 10 ml/kg of distilled water (negative control) and 1mg/kg of isometamidium chloride (positive control). The results of the pharmacological studies on the trypanocidal potential of the plant showed that On day ten (D10)  a mortality rates of 32 %, 39 % and 62 % respectively for the doses 250, 500 and 1000 mg/kg with the ethanolic extract while  the aqueous extract induced a mortality rates of 32 %, 37 % and 56 % respectively. Isometamidium chloride induced the highest mortality rate of 85 %. The lethal doses were 218.07 and 225.79 mg/kg for the aqueous and ethanolic extracts respectively. All these results justify at least in part the use of this plant in traditional medicine for the treatment of trypanosomiasis.

AbstractA field experiment was conducted to investigate the effect of aqueous and ethanolic extracts of neem (Azadirachta indica A. JUSS) and garlic (Allium sativum L.) against Cercospora leaf spot (CLS) disease of groundnut (Arachis hypogaea L.). A split plot design using two exotic (“fleur” 11 var., 65-13 var.) and one local (village var.) variety of groundnut as the main factor and ten treatments comprising one negative control (sterile distilled water), one positive control (fungicide: spavozeb) and eight phyto-extracts replicated three times was applied. Treatments were applied to plots at 45, 60, 75 and 90 days after planting (DAP). Results showed that CLS disease incidence ranged between 66.67% and 88.89% at 65 DAP for 10% ethanolic extract of garlic and 20% aqueous extract of garlic, respectively. Disease severity was lowest for 20% ethanolic extracts of neem seeds (14.74%) and garlic bulb (14.99%) at 65 DAP. Yield obtained from treatments of ethanolic extracts of garlic (3.62 t ha−1) was significantly higher (p < 0.05) than the control (2.40 t ha−1) but comparable to the spavozeb treatment (3.09 t ha−1). Exotic varieties were more productive (3.13 and 3.43 t ha−1) than the more resistant local variety (2.67 t ha−1).

Purpose: To evaluate the antitrypanosomal activity of Malva sylvestris (MS) extract in a Trypanosoma brucei brucei-infected  mouse model of sleeping sickness.Methods: Sleeping sickness was induced by the intraperitoneal injection of Trypanosoma brucei brucei infected blood in mice.  Confirmation of parasitaemia was performed by estimating the parasite count in the plasma on the 12th day after inoculation. All the mice were divided into five groups: control group that received neither infection nor treatment; negative control that was  infected with the parasite but did not receive treatment; MS-treated group that receive MS extract (250 and 500 mg/kg, ip) and standard (STD) group that received levamisole (7.5 mg/kg, ip) for 7 days after the development of parasitaemia. A further parasite count was performed in the blood and cerebrospinal fluid (CSF) after the treatment period. Humoral antibody response,  delayed hypersensitivity reaction, and mobilization of leucocytes were determined after the treatment period in SRBC-sensitized mice.Results: The results indicate that treatment with MS significantly decreased body weight and parasite count in the blood and CSF of mice with Trypanosoma brucei brucei-induced sleeping sickness compared with that in the negative control group. There was a significant increase in paw swelling and decrease in secondary antibody in the MS-treated group compared with that in the  negative control group. However, treatment with MS extract also enhanced the mobilization of the total leucocyte count compared with that in the negative control group.Conclusion: The results demonstrate the anti-trypanosomal activity of Malva sylvestris extract via immunomodulation in a  Trypanosoma brucei brucei-infected mouse model of sleeping sickness.Keywords: Malva sylvestris, Trypanosoma brucei brucei, Sleeping sickness, Immunomodulatory activity, Delayed hypersensitivity reaction

This study investigated the efficacy of different chemotherapeutic regimes in the treatment of rats experimentally infected with diminazene aceturate-resistant strain Trypanosoma brucei brucei. Thirty Sprague Dawley male rats used for the study were randomly assigned to six groups of five rats eachas follows: group A-uninfected untreated (negative control), group B-infected and untreated (positive control), groups C-F were infected and treated with 1.0 mg/kg isometamidum chloride, administered intramuscularly on day 11 post-infection. However, rats in groups D, E and F received further treatments with 700 mg/kg sodium-ethylenediamine tetra-acetic acid, 0.4 mg/kg verapamil and 3 mg/kg chlorpromazine, respectively, administered orally for four days. Clearance of parasite post-treatment (PT), mortality PT, relapse parasitaemia post-clearance, body weight change, rectal temperature, packed cell volume (PCV), haemoglobin (HB) concentration and red blood cell count (RBC) were determined during the experiment. Result showed parasite clearance PT of 100% in groups D and E, 80% in group F and 20% in group C by 24 hours PT. The infection relapsed on day 35 PT in 40% of rats in group C, on day 37 PT in 20% of rats in group F and lastly 20% of rats in groups D and E on day 39 PT. Rats that received drug combination showed marginal improvement in erythrocytic parameters analysed when compared with those treatment with isometamidium alone. Combination therapy showed faster clearance of parasite from the blood and also prolonged relapse post-clearance, thus had a better promising efficacy when compared to using isometamiduim chloride alone.
