ABSTRACT
Although radiation and surgery are generally regarded as effective for treatment of prostate cancer (PCa) in majority of men, diagnosis and prognosis remains poor in patients with progressive disease. Disease –specific metabolites represent the effective end points with considerable ability to identify men at increased risk of disease progression. In the current study, serum levels of Sarcosine, free and total testosterone (fTesto and tTesto) were assayed to evaluate the tumorigenic properties of PCa in our locality. In this study, 150 prostate cancer, 200 benign prostatic hyperplasia (BPH) Patients diagnosed and 200 volunteer matched controls were evaluated. Serum sarcosine were 64.94±0.81 nmol/dl, 118.70±1.80 nmol/dl and 134.13±2.21 nmol/dl in PCa, BPH patients and controls respectively. Serum tTesto and fTesto levels were 5.09±0.15 ng/ml, 5.12±0.11 ng/ml and 13.42±0.26 pg/ml, 5.72±0.20 ng/ml, 13.93±0.24 ng/ml and 11.73±0.47 pg/ml in PCa, BPH patients and controls respectively. Values differ significantly (p˂0.05) between PCa, BPH patients and controls in all the analytes. Attempt was also made to define the reference ranges of these analytes in various age groups of the controls. We recommend the inclusion of Serum levels of Sarcosine, tTesto and fTesto into multiplex biomarker panel for PCa and BPH detection in our localities.
ABSTRACT
Evaluation of hypoglycaemic activity of ethyl acetate and n-butanol fractions of Acacia nilotica on alloxan induced diabetic Wistar rats has been investigated. Two doses of the ethylacetate fraction 50 and 100 mg/kg was administered. As regard to 50mg/kg caused a significant (P<0.05) reduction in the blood glucose levels when compared with control at 3,5,7,9 and 12 days of treatment with percentage glycaemia change of 49.1,54.8,60.5, 58.8 and 69.7 respectively. However, the dose of 100mg/kg ,there was a significant decrease (p<0.05) at 3 5 7, 9 and 12 days treatment when compared to control untreated with percentage glycaemia change of 50.1,56.8, 52.8, 69.9 and 59.6 . Also two doses of n-butanol, 100 and 200 mg/kg fraction was administered to the diabetic rats. The dose of 100 mg/kg, there was a significant decrease (p<0.05) after 7 and 12 days of treatment when compared to untreated control. As regard the dose of 200 mg/kg, there was a significant decrease ( p<0.05) at 3, 5 ,7,9 and 12 days of treatment when compared to control untreated with percentage glycaemic change of 20.7,35.3,52.3, 44.2 and 40.9 respectively. The preliminary phytochemical screening revealed the presences of saponin, flavonoid, tannin and alkaloid. The median lethal dose (LD50) in mice was calculated to be 471.2 mg/kg bodyweight. This result suggests that the Ethylacetate and n-butanol fractions of leaves methanolic extract of Acacia nilotica possess antidiabetic effects on alloxan - induced diabetic Wistar rats.
