Anxiety is among the most prevalent and costly diseases of the CNS, but its underlying mechanisms are not fully understood. Although attenuated theta rhythms have been observed in human subjects with increased anxiety, no study has been done on the possible physiological link between these two manifestations. We found that the mutant mouse for phospholipase(More)
Curcumin, an active principle component in rhizome of Curcuma longa, has proved its merit for diabetes through its anti-oxidative and anti-inflammatory properties. This study aims at evaluating the effect of curcumin in modulating the altered dopaminergic receptors, CREB and phospholipase C in the cerebral cortex and cerebellum of STZ induced diabetic rats.(More)
AIMS Chronic hyperglycaemia in diabetes involves a direct neuronal damage caused by intracellular glucose which leads to altered neurotransmitter functions and reduced motor activity. The present study investigated the effect of curcumin in the functional regulation of muscarinic and alpha7 nicotinic acetylcholine receptors, insulin receptors, acetylcholine(More)
Gamma amino butyric acid is a major inhibitory neurotransmitter in the central nervous system. In the present study we have investigated the alteration of GABA receptors in the brain stem of rats during pancreatic regeneration. Three groups of rats were used for the study: sham operated, 72 h and 7 days partially pancreatectomised. GABA was quantified by(More)
AIM In the present study we have investigated the changes in the total muscarinic and muscarinic M1 receptor ([(3)H]QNB) binding and gene expression in the cerebral cortex of streptozotocin (STZ) induced diabetic, insulin and aqueous extract of Aegle marmelose leaf treated diabetic rats. MATERIALS AND METHODS Diabetes was induced in rats by intrafemoral(More)
The brain neurotransmitters' receptor activity and hormonal pathways control many physiological functions in the body. Acetylcholine (ACh), a major neurotransmitter from autonomic nervous system, regulates the cholinergic stimulation of insulin secretion, through interactions with muscarinic receptors. The objective of the present study was to investigate(More)
Acetylcholine (ACh), the first neurotransmitter to be identified, regulate the activities of central and peripheral functions through interactions with muscarinic receptors. Changes in muscarinic acetylcholine receptor (mAChR) have been implicated in the pathophysiology of many major diseases of the central nervous system (CNS). Previous reports from our(More)
AIM OF THE STUDY The leaves of Costus pictus D. Don were used extensively for its antihyperglycemic activity by the people in Kerala, India. In the present study, the antihyperglycemic and insulin secretory activity of an aqueous extract of Costus pictus leaf extract was investigated in streptozotocin induced diabetic rats. MATERIALS AND METHODS Oral(More)
Oro-facial-digital syndrome type II (OFD-II) is characterized by frenulated tongue, midline cleft lip, high arched or cleft palate, micrognathia, syndactyly and polydactyly, bilateral reduplicated hallux, conductive hearing loss, choroidal coloboma and normal intelligence. There are nine forms of oro-facial-digital syndromes with different modes of(More)
