Phytochemicals and in vitro antioxidant potentials of defatted methanolic extract ofHolarrhena floribunda leaves

Plant-based dietary components and additives are known to protect cells from deleterious effect of reactive oxygen species (ROS). Proximate, phytochemical and antioxidant potentials of methanolic extract of defatted Holarrhena floribunda (G.Don) leaves were assessed using in vitro systems such as, 1,1 diphenyl-2-picrylhydrazyl (DPPH) radical, hydroxyl radical, nitric oxide radical scavenging and inhibition of lipid peroxidation. Total antioxidant activity was measured using phosphomolybdenummethod. Total phenol content and the reductive potential of the extract were also evaluated. The results of the proximate analysis revealed that the leaf contained 0.23% moisture, 12.8% ash, 9.62% crude fat, 23.3% crude fibre, 21.17% protein and 32.68% carbohydrate while the phytochemical constituents included alkaloid, saponin, tannin and cardiac glycosides. The leaf extract of H. floribunda (G. Don) exhibited scavenging activity with IC50 of 12.63, 1,377.00 and 244.00 ìg/ml for DPPH, hydroxyl radical and nitric oxide radical respectively. The extract conferred 50% protection at the concentration of 73.80 ìg/ml on lipid peroxidation induced by FeSO4 in egg yolk. Total antioxidant capacity equivalent of gallicacid and vitamin C were 195.57 and 519.28 g/mg of extract respectively and total phenol content equivalent of gallic acid was 1427.87 ìg/mg. The reductive potential increased with increasing concentration of extract. The results obtained from this study reveal that the extract is rich inantioxidant components with several mechanisms of eliciting antioxidant actions which provide scientific basis for its use in folk medicine

Hypoglycaemia among adults with Type 2 Diabetes mellitus in a Family Medicine Clinic

Background: The prevalence of Diabetes mellitus (DM) is increasing worldwide. The complications of DM arising from hyperglycaemia are well documented and. However, there is a lack of data, poor awareness and information on hypoglycaemia in DM. Objective: To describe the prevalence and factors associated with hypoglycaemia among patients with Type 2 Diabetes mellitus (DM). Methods: This was a retrospective study of the clinical records of patients with Type 2 DM at the Family Medicine Clinic of a Nigerian teaching hospital from January 2019 to January 2020. The sociodemographic and clinical characteristics, including hypoglycaemia, Glycosylated Haemoglobin (HbA1c), Fasting and Random blood glucose, were retrieved. Results: A total number of 570 patients were assessed, with a prevalence of 43 (7.5%) of hypoglycaemia. The mean age of the patients in the study was 58.2±10.9 years (range: 36-83 years). Metformin (557; 97.7%), Sulphonylureas (377; 66.1%), Dipeptidylpeptidase -4 inhibitors (137; 24.0%) and insulin (72; 12.6%) were the most prescribed anti-diabetic medications. hypoglycaemiaA majority (29; 67.4%) of the hypoglycaemia episodes occurred in the morning, while most (24; 55.8%) of the episodes of hypoglycaemia were mild. Mean age (t= 2.35; p = 0.019), presence of hypertension (X2 = 6.92, p = 0.008) and dyslipidaemia (X2 = 7.86, p = 0.005) were associated with hypoglycaemia. Conclusions: The prevalence of hypoglycaemia in the Outpatient clinic was low, while the presence of comorbidities                                   (hypertension and dyslipidaemia) and age were associated with hypoglycaemia. There is a need for patient education and Self-Monitoring of Blood Glucose (SMBG) to prevent complications of hypoglycaemia. hypoglycaemia
