ABSTRACT

In humans, malaria in pregnancy can cause serious maternal and foetal morbidity and in extreme untreated cases, foetal mortality occurs. The therapeutic approach to curbing this malaise is the administration of an effective and/or combinations of anti-malaria medicaments. Acute or chronic administration of some of these drugs, however, gives rise to some adverse medical conditions including reproductive dysfunction, especially in pregnancy. Studies aimed at the hormonal interplays following administration of these drugs in pregnancy have been limited due to too few appropriate animal models. In this experiment, pregnant albino rats were infected with rodent parasite, Plasmodium berghei on the 5th day of gestation, following which biochemical changes, specific for pregnancy maintenance were monitored in the blood of test rats. We observed that infecting the pregnant rats with P. berghei negatively impacted the measured biological parameters (hormones) compared to unchallenged controls. The observed effect was however retreated following oral administration of 3mg/kg body weight, qDay of Artesunate until the 17th day of gestation. Findings, therefore, suggest that Artesunate is an effective therapeutic agent in pregnancy, demonstrated by the restoration of the hormonal changes occasioned by the parasitic infection.

ABSTRACT

BACKGROUND: The fruit extract of Dacryodes edulis (D. edulis), the African pear or plum, a tree indigenous to the humid tropics has been used for managing wounds, skin diseases, sickle cell anaemia, dysentery and fever in some African nations. In South Eastern Nigeria, 'herbal doctors' include its marshed fruit in decoctions administered to diabetic patients. However no scientific substantiation of their claim and use exist in literature. Hence, the need to evaluate the antidiabetic and hypolipidaemic activity of hexane extracts of D. edulis fruit in alloxanised animal model. MATERIALS AND METHODS: Sub-toxic doses between 400 and 1600mg/kg were orally administered sub-chronically to alloxan-induced diabetic rats for 15 days and compared to glibenclamide (2.5mg/kg). The glycaemia levels, body weights, lipid profile, blood urea, creatinine and liver enzyme levels were measured. Basic histology of the pancreatic tissue was also performed to examine the effects on the pancreas as possible mechanistic lead. RESULTS: Oral acute dosing of D. edulis hexane extract decreased blood glucose levels, while sub-chronic treatment of the extract down-regulated significantly hyperglycaemia, total cholesterol, triglycerides, LDL-C, ALT and ALP levels. However, the HDL-C levels increased significantly. Histopathological examination of the pancreatic tissues after sub-chronic treatment showed that glibenclamide and the highest dose of the extract 1600mg/kg restored the afore-damaged pancreatic ß-cell architecture. CONCLUSION: Our findings portend that D. edulis hexane fruit extract possesses hypoglycaemic and hypolipidaemic activities as well as restoration of the pancreatic architecture without any obvious untoward hepatic damages, suggesting that its use in the management of the diabetes may be valid.
