Kidney transplantation offers the best solution for the problem. The shortage of donor kidney is even bigger problem due to transplantation being one of the routine procedures. The use of deceased donor definitely increases the pool of donor with excellent immediate and long-term follow-up proven results. Aim: The aim is to analyze and summarize the outcome of Kidney transplantation. Methods & Materials: A total of 78 cases of Kidney Transplantation were selected for the study and categorized as: Group I—41 (living Donor), Group II—23 (DCD) & Group III—15 (DBD). Perspective study was done with clean data recorded & maintained pre-operatively, post-operatively and follow-up from Jan 2011 to Dec 2015 in our hospital. Post-operative graft status, complications and at least 1-year follow-up were area of main focus. Results: All patients underwent successful kidney transplantation. In Group I, the number of living donor kidney transplantation is 41 whereas in Group II (DCD) & III (DBD), the number of deceased donor transplantation is 23 and 15 respectively. The Normal functioning of graft (NGF) was 38 (87.8%), 16 (69.6%) & 11 (73.3%) in Group I, II & III respectively along with Poor Graft function (PGF) in Group I—4 (9.7%), II—5 (21.7%) & III—2 (13.3%) managed by continuing dialysis. Delayed graft function (DGF) was noted I-1 (2.4%), II-2 (8.6%) & III-1 (6.6%) in respective group, which returned to normal function post intervention. Therefore, 1<sup>st</sup> year graft survival was >93% [(Group I (97.6%), Group II (95.6%) & Group III (93.3%) respectively]. Manageable surgical complication were found in Group I—8 (19.5%), Group II—5 (21.7%) & Group III—2 (13.3%) like hematoma, hydronephrosis, leakage except one emboli related nephrectomy of transplanted kidney & one pneumonia led death in Group II. The overall survival was greater than 90% [(Group I (97.6%), Group II (91.3%) & Group III (93.3%) respectively] in all three groups after at least 1-year follow-up study, which was an excellent prognosis. Conclusion: Kidney Transplantation is safe, effective and the best method of treatment for ESRD. Significant improvement in quality of life is the hallmark merit over dialysis. Paired donation program should be encouraged in order to overcome shortage of kidney, which increases living donor pool. Outcome in living donor Kidney transplantation is always better than deceased donor transplantation. The prognosis of deceased donor transplantation (1 year Graft survival > 93% & 1 year patient survival > 90%) is also satisfactory with promising results. Therefore all the results were under acceptable standard limit. Thus, kidney transplantation (live or deceased donor) should be encouraged as primary modalities in the treatment of End Stage Renal Disease (ESRD).展开更多

As licorice compounds are potent antioxidants, our aim was to examine whether magnesium isoglycyrrhizinate attenuated lipid peroxidation, the major end-point of oxidative damage resulting from ethanol administration. Methods： Four groups（18 animals in each group） of male Kunming mice were used. The first group served as control and received 0.4 ml normal saline daily for 18 days orally. The second group of mice was given 56% ethanol at 16 ml/kg body weight per day for 18 days orally. The third group was given the same dose of ethanol and administrated magnesium isoglycyrrhizinate （15 mg/kg.d, i.p.） for 18 days. The fourth group was given the same dose of ethanol and administrated with magnesium isoglycyrrhizinate （45 mg/kg.d, i.p.） for 18 days. Twenty four hours after 9 days or 18 days of treatment the mice were sacrificed using 10% chloral hydrate. Sperm counts and motility in the epididymis were assessed. The lipid peroxidation and antioxidants of testicular mitochondria were also determined. The pathological changes of testicle tissue of the mice were observed by light microscopy. Results： Magnesium isoglycyrrhizinate effectively prevented the ethanol-induced seminiferous epithelium disorganization and degeneration of Sertoli cells and germ cells. Sperm counts and motility of the magnesium isoglycyrrhizinate treated groups were higher than those of the alcohol treated group, but were lower than those of the control group. The drug exhibited an ability to counteract ethanol induced oxidative challenge as it effectively reduced testicular malondialdehyde （MDA） and increased the activities of superoxide dismutase and glutathione peroxidase. Conclusion： Magnesium isoglycyrrhizinate is able to inhibit the ethanol-induced lipid peroxidation and has a protective effect against testicular oxidative injury.展开更多
