Abstract:
In the present study a detailed investigation on the alterations of dopamine
and its receptors in the brain regions of streptozotocin induced diabetic and insulin
induced hypoglycaemic rats were carried out. Glutamate receptor, NMDARI gene
expression in the hypoglycaemic and hyperglycaemic brain was also studied. EEG
recording in hypoglycaemic and hyperglycaemic will be carried out to measure brain
activity. in vitro studies on glucose uptake and insulin secretion, with and without
specific antagonists were carried out to confirm the specific receptor subtypes - DA
D1, DA D2 and NMDA involved in the functional regulation during hyperglycaemic
and hypoglycaemic brain damage. The molecular studies on the brain damage
through dopaminergic and glutamergic receptors will elucidate the therapeutic role in
the corrective measures of the damage to the brain during hypoglycaemia and
hyperglycaemia. This has importance in the management of diabetes and antidiabetic
treatment for better intellectual functioning of the individual.

Abstract:
The thesis comprises a set of experiments mainly focused on the
improvement of L-glutamic acid fennentation. Much attention has been given to
use of locally available raw materials, culturing the organism on inert solid
substrates and also immobilization of the bacterial cells from the view point of long
term utilization of biocatalyst and continuous operation of the stabilized system.
Studies were also carried out for the down stream processing for the extraction and
purification of L-glutamic acid. An attempt was made to study the morphological
features of the microorganism including the cell premeability. In relation with the
accumulation of glutamic acid within the cells an approach was made to study the
behaviour of the Brevibacterium cells when they are exposed to hyper osmotic
environment. Attempts were also made to study the requirement of iron and
production of siderophores by this microbial strain. The search for a suitable
nitrogen source for glutamate fermentation ended with a promising result that they
got a potent urease activity and it can be utilized for many biotransfonnation
studies.
The entire thesis is presented in three sections, viz. introductory section,
experimental section and the concluding section
