The present study was to investigate the rote of central 5-11T and 5-HT,:v receptor Lindin4o and acne expression in it 'at mo(lel of pancreatic regeneration using 60" -, pancreatcutumy. The pancreatic regeneration was evaluated by 5-HT content and 5-HT,,receptor gene expression in the cerebral cortex (CC) and brain stem MS) of Alain opcrate,t, 7 It utd 7 (.lays panereatectomised rats. 5-11T content significantly increased in the CC' (I' 1.1)11 and 13S (P 0.05) of 72 Ii p.ntcreateetomiscd rats. Sympathetic activity was decreased as indicated by the significantly decreased norcpiuephrine (NIi) and epinephrine (FTI) Icvcl (1' < 0.001 and P < 0.05) in the plasma of 72 h panereateetomised rats. 5-111 ,^, receptor density and affinity was decreased in the CC (P < 0.01) and BS (P < 0.01). These rh:)nge; correlated with a diminished 5-IITIA receptor mRNA expression in the brain region. studied. Our resuils suggest that the brain 5-11T through 5-HTin receptor has it funcuon:0 rule iii 11w pi+ncreatic regcner:ttion through the sympathetic regulation.

A comparative study of Glycogen phosphorylase from selected Cephalopods is reported in this thesis. A detailed investigation of an important glycolytic enzyme, phosphorylase, from a selected species, is undertaken. Loligo vulgaris, commonly known as squid, is selected as the source for the study. Phosphorylase is the key enzyme in the mobilization of chemical energy from glycogen and its role in the regulation of carbohydrate metabolism is well established. Although a good deal of information is available about phosphorylase from terrestrial animals, not much is known about the enzyme from aquatic fauna. In order to bridge this gap and also to compare the results with the findings from other sources, phosphorylase a was isolated from this marine mollusc and its properties studied in detail in this study
