Glycogen content of the prawn muscles from the three groups showed increasing trend after 30 days of feed supplementation. In control animals recorded maximum of 2.2 mg/g, and inB. coagulanssupplemented animals it was 4.1 mg/g and 3.6 mg/g inB. firmussupplemented animals increase in glycogen content in relation with feed supplementation with probiotic bacteria was most prominent in prawns. The increase in alpha amylases content may be attributed to the influence of the probiotic strain which possess exoenzyme activity. Maximum colonies were found inB. firmussupplemented animals gut, 962 cfu after 30 days of feed supplementation. Similar trend wasobserved in intestinal microflora of all three groups after infection in the feed supplemented animals. The one way analysis of variance showed significant variation among feed supplementation and treatment. The one way analysis revealed thatB. coagulanssupplemented group recorded maximum glycogen followed byB. firmusand control groups. Maximum THB count was observed inB. firmussupplemented animals after infecting the animals withV.parahaemolyticus. Alpha amylase activity was maximum inB. firmussupplemented animals was recorded. Significant results could be observed in one way analysis of variance.

Diabetes ranks among the top 5 killer diseases of the current world population. Transplantation of pancreatic islets is a common surgical procedure used to combat the late stage diabetic complications. A successful and long lasting islet transplant is an enigma as the complex immunoactivation mechanisms against the transplants, the subsequent graft rejection and the proper maturation and functioning of the islets in the host microenvironment, are the subjects of research for many years. This review details certain recent studies performed upon primate, porcine, murine and rabbit models, in relation to islet transplantation, with a critical standpoint.
