Background: Research for new antimalarial drugs remains a permanent quest for the control of malaria. Objective: The present study investigates the effects of the aqueous extract of Entandrophragma angolense bark on P. berghei-induced malaria in mice. Methods: Eight weeks old mice, were intraperitoneally infested with 200 μl of blood, containing 1x106 P. berghei-infected-erythrocytes. Parasitaemia was determined using a 10\% giemsa stained blood smear read under optical microscope (x100). The infected animals were randomized into 5 groups of 10 animals each and daily treated for 5 days with the plant extract at 125, 250 and 500 mg/kg. The normal control and malaria control received water while the chloroquine control was treated with 10 mg/kg of chloroquine. Body weight, parasitaemia and survival time were monitored daily during treatment and follow up periods. Five animals from each group were sacrificed under anaesthesia at the end of treatment (d8) and after the follow up period (d28). Venous blood was used for haematological and biochemical tests. Organs (liver, kidneys and spleen) were also collected for biochemical and histological analyses. Results: Administration of the aqueous extract of E. angolense bark to infected mice significantly inhibited parasite development (p \<0.001) with ED50 estimated at 25.32 mg/kg. The extract prevented animal from death, body weight loss, anaemia, leucocytosis, high transaminases (ALT and AST), high bilirubin, creatinine and MDA levels, oxidative stress and anatomical alteration in organs as compared to the malaria control. Conclusion: The E. angolense bark possesses antimalarial properties, supporting its use in traditional medicine to treat malaria.

Background: The increasing incidence of dermatophytoses in the world and the side effects of the current therapies encouraged the search of alternative drugs. Hence the objective of this work was to determine antidermatophytes activity of Syzigium aromaticum formulate antidermatophytic cream. Materials and Methods: The extracts were prepared by maceration of plant materials into methanol. Three formulations of creams were made, and the best was chosen according to its physicochemical stability and appearance. The acute dermal toxicity and antidermatophytic efficacy of the cream was performed on guinea-pig. Results: The methanolic extract of S. aromaticum was incorporated in the final cream formulation. The formulation containing shea-butter 58.5\%, acetylic alcohol 2.5\%, stearic acid 1.5\%, bee-wax 10\%, borax 1.5\%, polysorbate 60 2.5\%, 2 drops of lactic acid and water was chosen because of its good appearance and stability. The cream with methanolic extract of S. aromaticum did not reveal any dermal toxic effect. The cream efficacy was dose-dependent. The treatment with cream at 5\% methanolic extracts of S. aromaticum revealed the best potency after 14 days of treatment. Conclusion: These results show that the cream at 5\% methanolic extract of S. aromaticum seed is promising in the treatment of dermatophytoses and could be used as an alternative in the development of a new therapy.
