Their use in folk medicine and phytomedicine is in the treatment and management of variety of human ailment, like diabetes mellitus, abdominal problems etc. The search for new antidiabetic therapies has become increasingly urgent due to the development of adverse effects and resistance by the chemically synthesized drugs on one hand and effectiveness with low cost of the plant materials on the other hand. The investigations carried out is to determine the long term effects of Costus afer leaf methanol extract, snail slime and the combined Costus afer and snail slime extracts on blood glucose levels of alloxan induced diabetic Swiss albino rats treated orally for 21 days on graded dose of (100 mg/kg and 300 mg/kg). From the determination, the snail slime showed positive effect on blood glucose lowering level but less effective when compared with similar dose of the Costus afer leaf methanol extract. The investigation indicated that there was 103 mg/dL and 87 mg/dL blood glucose reduction for the low dose of Costus afer and Snail slime respectively while the standard hypoglycemic drug (Glibenclamide, 5 mg/kg) used for comparison yielded a blood glucose level reduction of 103 mg/dL. Similarly, the high dose used in the study gave a blood glucose reduction of 99 mg/dL and 95 mg/dL for Costus afer leaf methanol extract and Snail slime respectively. The results obtained when alloxan induced rats was treated with C. afer leaf methanol extract, Snail slime extract, and combined C. afer and snail slime extracts was analysed using Statistix 8.0 American version. The result showed a dose dependent fashion and the difference obtained from the compared results was statistically significant at p 1]. Still to that, medicinal and pharmacological activities of medicinal plants are often attributed to the presence of the so called secondary plant metabolites. Hence this regenerative capacity of snail slime and the fact that diabetes is characterized by damage of the pancreatic beta cells, may give credit to the hypoglycaemic effect observed in Costus afer methanol leaf extract and snail slime for possible drug formulation for anti-diabetic remedy. Our findings may approve snail slime which is insoluble in both acid and alkaline medium, to act as a carrier of chemical and biological nanoparticles for medical and pharmaceutical use.展开更多
