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.

In the present study, a detailed investigation on the alterations of muscarinic M1, M3, α7 nicotinic acetylcholine receptor (α7 nAchR), GABA receptors and its subtypes; GABAAα1 and GABAB in the brain regions of streptozotocin induced diabetic and insulin induced hypoglycemic rats were carried out. Gene expression of acetylcholine esterase (AChE), choline acetyltransferase (ChAT), GAD, GLUT3, Insulin receptor, superoxide dismutase (SOD), Bax protein, Phospholipase C and CREB in hypoglycemic and hyperglycemic rat brain were studied. Muscarinic M1, M3 receptors, AChE, ChAT, GABAAα1, GABAB, GAD, Insulin receptor, SOD, Bax protein and Phospholipase C expression in pancreas was also carried out. The molecular studies on the CNS and PNS damage will elucidate the therapeutic role in the corrective measures of the damage to the brain during hypoglycemia and hyperglycemia.
