Hypoglycaemia and improved testicular parameters in Sesamum radiatum treated normo-glycaemic adult male Sprague Dawley rats

The development of a new dietary adjunct with a novel natural antioxidant impact on diabetes mellitus with prevention of its long term deleterious effect on the male fertility in general has been increasinglyexpressed in recent time. Hence, we aim to evaluate the effects of aqueous extract of Sesame radiatum leaves on adult male Sprague Dawley rats’ testis using unbiased stereological, biochemical andhormonal studies. Thirty adult male rats were divided into three groups of 10 rats each. The treated groups; 1 and 2 received 28.0 and 14 mg/kg bwt of aqueous extract of sesame leaves via oral garvage,respectively, while the control group received equal volume of 0.9% (w/v) normal saline per day for 6 weeks. Serum follicle-stimulating hormone (FSH), testosterone and blood glucose were assayed. Inaddition five microns of uniformly random transverse sections of processed testicular tissues were equally analyzed using an un-biased stereological study. The result showed that the mean percentagevolume fractions (Vf) of epithelial cells and lumen of the testis were 76% (

Production of cell wall enzymes in pepper seedlings, inoculated with arbuscular mycorrhiza Glomus etunicatum

Pepper seedlings inoculated with arbuscular mycorrhizal AM fungus, Glomus etunicatum, produced cellulase, polygal-acturonase and pectin methylestrase enzymes. The activities of the enzymes increased as the pepper seedlings matured in age, showing that the activity of the enzymes in the seedlings was age mediated. The pectinases showed higher activity than the cellulase enzyme which may indicate establishment of the mycorrhizal in the host. The significance of this finding is that there is an initial infectivity factor in (AM) fungi interactions with plant just like in other host-parasite interaction.
