OBJECTIVE:To investigate the anti-oxidative and anti-nephrotoxic effects of resveratrol in cisplatin induced nephrotoxic albino Wistar rats. METHODS:This quasi-experimental study was performed at Isra University, Hyderabad, Pakistan. Thirty male albino Wistar rats were divided into three g r o u p s : g r o u p -A ( c o n t r o l ) , g r o u p -B ( c i s p l a t i n ) a n d g r o u p -C (cisplatin+resveratrol). Biochemical [serum urea, creatinine and glutathione peroxidase (GPX)] and renal histomorphology was performed in all groups after 21 days of treatment. RESULTS:Difference in mean pre-and post-experimental body weight was observed in all three groups. Mean body weight decreased from 241.7±8.5 gm to 196.50±9.34 gm and from 237±7.4 gm to 207.2±6.56 gm in group-B and group-C respectively. In group-A; mean serum urea was 22.7±2.66 mg/dl, serum creatinine was 0.45±0.05 mg/dl and serum GPX was 1.44±0.13 ηg/ml. In group-B; mean serum urea level was 51±3.65 mg/dl, mean serum creatinine was 0.78±0.05 mg/dl and serum GPX was 0.85±0.11 ηg/ml. In group-C, mean serum urea level was 32.8±1.45 mg/dl, serum creatinine level was 0.41±0.09 mg/dl and serum GPX was 1.53±0.08 ηg/ml. In group-A, renal structure was intact, marked changes were observed in renal histology of group-B while group-C displayed less glomerular damage. The mean distance between visceral and parietal layers of Bowman's capsule was 69.34±0.87 µm in group-A, 216.5±1.32 µm in group-B while 102.22±1.65 µm in group-C. Areas of peritubular fibrosis and congestion were observed in groups B and C but less prominent in group-C compared with group-B. CONCLUSION:Resveratrol therapy is a potent anti-nephrotoxic regime showing promising results in chemotherapy induced nephrotoxicity and oxidative stress.
Bacillus subtilis NRRL 365 produced high extracellular carboxyl esterase activity in submerged culture media containing wheat bran, corn steep liquor, and salts. Supplementation of this medium with glucose reduced esterase activity to 37% of that in the unsupplemented control. Esterase activity was purified by ammonium sulfate fractionation, DEAE-Sephadex A-50 ion-exchange chromatography with sodium chloride gradient elution, and preparative polyacrylamide gel electrophoresis. The resultant purified components, esterases I and II, manifested single bands following silver staining of polyacrylamide gel electrophoresis gels and had final specific activities of 80 and 520 U/mg, respectively. Molecular weights for components I and II were 36,000 and 105,000 to 110,000, respectively. Esterases I and II both had a pH optimum of 8.0, with relative activities of 10 and 85%, respectively, at pH 9.0. Kms with p-nitrophenylacetate were 0.91 mM for esterase I and 0.67 mM for esterase II. In general, patterns of enzyme inhibition were similar for both components. Differences were observed in the relative activities of esterases I and II towards p-nitrophenyl esters of acetate, propionate, and butyrate; Activity ratios for components I and H were 100:94:48 and 100:36:23, respectively. The purified components did not hydrolyze long-chain triglycerides and did not manifest proteolytic activity.
Diabetes mellitus is chronic condition with defect in regulation of insulin. Microalbuminuria is one of the early appearing markers of overt diabetic nephropathy. Uncontrolled glycemic status has been postulated to be associated with increase urinary albumin levels. Objectives: To find out the association of increased urinary albumin with poor glyemic status of patients with diabetes mellitus type II. Study Design: Cross Sectional study. Setting: Department of Pathology, Indus Medical College Hospital Tando Muhammad Khan. Period: November 2018 to June 2019. Material & Methods: Patients were divided into two groups: Group I (Poor glycemic control, HbA1c >7%) and Group II (Good glycemic control, HbA1c <7%). Glycated hemoglobin and microalbuminuria were evaluated in all patients. Data was analyzed using SPSS 21.0. P – value of <0.05 was considered as statistically significant. Results: Total of 213 patients were included in the study with male ratio (56.8%) slightly higher than females (43.19%). Mean age of patients was 42.3 ± 2.1 years. Mean glycated hemoglobin in Group I and II was 8.12 ± 0.97% and 5.98 ± 0.41% respectively. In Group I, 57.54% patients were detected with microalbuminuria as compared to Group II (12.26%). P value was statistically significant (<0.001). Conclusion: Microalbuminuria was found more frequently in patients with poor glycemic control. Early detection of urinary microalbumin in these patients may decrease the risk of kidney damage and appropriate and adequate management in initial stage.
Human recombinant EGF, secreted into the extracellular medium by E. c&i cells, was purified by a combination of solid phase extraction and HPLC. Using these techniques, the peptide was purified 122-fold, with a recovery of greater than 75%. The purified hEGF manifested no contaminating protein bands on electrophoretic gels. Amino acid analysis of the purified peptide was identical to that of authentic hEGF.
