Résumé
Fertility enhancement effect of ethanol extract of leaf of Melastoma malabathricum was observed in male albino rats. The relative weight of the testis and epididymis were increased. The epididymal sperm count, motility and sperm abnormality were increased significantly in treated rats. There was an increase in serum protein, albumin, globulin, urea, creatinine and the activity of liver marker enzymes (SGOT, SGPT and ALP) levels of treated rats. The activities of serum antioxidants (CAT, SOD. GPX, GST and GRD) in leaf extract treated rats were increased. The results of the hormonal assay showed that increased serum levels of LH and testosterone but decreased in the serum levels of FSH and estrogen compared to control. The results of fertility test indicated that the treated adult male rats increased the number of female’s impregnation. In addition, the number of implantations and the number of viable fetuses were also increased. The results of the present study concluded that, ethanol extract of leaf of Melastoma malabathricum enhanced sperm concentration, motility and testosterone which might produce positive result in the male fertility.
Résumé
The effect of ethanol extract of whole plant of Cynoglossum zeylanicum on Oral Glucose Tolerance was determined. Ethanol extract of Cynoglossum zeylanicum were evaluated for Oral Glucose Tolerance Test (OGTT) in normal and alloxan induced diabetic rats. Oral administration of ethanol extract at doses of 100 &150mg/kg body weight shows that the extract promote glucose uptake. These results suggest that the ethanol extract of Cynoglossum zeylanicum whole plant will be useful in the treatment of impaired oral glucose tolerance.
