ABSTRACT
BACKGROUND & OBJECTIVES: Living unrelated donor (LURD) renal transplantation has shown a rising trend over the last 5 yr at our center following the passing of The Transplantation of Human Organs Act by the Government of India in 1994. In this paper, the results of LURD and cadaver (CAD) donor renal transplantation are compared. We have also looked into factors that have a bearing on graft survival such as the extent of HLA mismatch (MM), infections, acute rejections (AR), donor age and sex. METHODS: A total of 42 LURD and 25 CAD renal transplants performed between March 1994 and February 1999 has been included in the study. HLA typing, panel reactive antibody (PRA) screening and T and B cell cross match assay were performed by the complement dependent cytotoxicity (CDC) method for all patients. RESULTS: The graft survival rates were generally higher in the LURD category as compared to the CAD group and were significant at 6 month period (90 vs 56%, P = 0.002). A follow up of the patients up to 60 months revealed a matching effect since the 3, 4 allele MM group had better survival rates as compared to the 5, 6 MM group. Twenty six of the 67 recipients (39%) experienced episodes of acute rejection (AR). Patients with 3, 4 MM had fewer such episodes than those with 5, 6 allele MM (P < 0.05). Of the 32 deaths, 20 were those with a functional kidney, of which 15 were caused by severe infections. INTERPRETATION & CONCLUSION: Better HLA matching ensures fewer episodes of rejection and better long term graft survival in comparison to the poorly matched grafts. The graft survival for LURD recipients was appreciably higher than that of CAD recipients.

The Hepatitis C Virus (HCV) is a major cause of post transfusion hepatitis. The introduction of HCV antibody screening has reduced the risk of post transfusion hepatitis significantly. However, the test is yet to be used routinely in blood banks of several developing countries with limited resources. We have developed an Enzyme immunoassay using synthetic peptides. The test was compared to seven commercial tests available in the Indian market. The test was evaluated using a panel of 90 sera which were chosen from an earlier panel based on detection of HCV RNA by Reverse Transcription Polymerase Chain Reaction RT-PCR. In case of any discrepancy the sera were further analysed by Line immunoassay (LIA). The sensitivity of the in house EIA was 90%. The specificity of the commercial EIAs varied.

The preferred food items of the slugs Laevicaulis alte and the snails Achatina fulica were used to prepare 'poison baits'by injecting the pesticides 'Rogor'and 'Nuvan'to kill these mollusc pests. The 'poison baits'prepared with Thrichosanthes dioica and Lycopersicum esculentum were accepted by 100% individuals of both the species irrespective of the pesticides used. In all cases the slug and the snail individuals died within a considerable length of time following consuption of the bait. The importance of using 'poison bait'lies not only with the sure success in killing the pests but also with the 'safe use'of toxic materials in order to avoid environmental hazards
