Item Correlation of health morbidity to air pollutant levels in Bombay City: results of prospective 3 year survey at one year.(1980-01-01) Kamat, S R; Godkhindi, K D; Shah, B W; Mehta, A K; Shah, V N; Gregrat, J; Papewar, V N; Tyagi, N K; Rashid, S S; Bhiwankar, N T; Natu, R BItem Effect of various pharmacological agonists on the rat caecum-appendix preparation: a preliminary study.(1982-10-01) Mehta, A K; Kulkarni, S K; Singh, MA preliminary study with various pharmacological agents revealed the presence of contractile muscarinic and H1-histamine receptors as well as inhibitory alpha- and beta-adrenoceptors and purinoceptors in rat caecum-appendix. Histamine also produced indirect actions mediated through the release of catecholamines. 5-Hydroxytryptamine produced variable response, the contractile response was mediated through 5-HT receptors and the relaxant response through the release of catecholamines.Item Esophageal electrocardiography.(1985-03-01) Mehta, A K; Daruwala, D F; Desai, A G; Sharma, S; Hansoti, R CItem Pharmacological effects of Withania somnifera root extract on GABAA receptor complex.(1991-08-01) Mehta, A K; Binkley, P; Gandhi, S S; Ticku, M KA methanolic extract of W. somnifera root inhibited the specific binding of [3H]GABA and [35S]TBPS, and enhanced the binding of [3H]flunitrazepam to their putative receptor sites. The extract (5 micrograms) inhibited [3H]GABA binding by 20 +/- 6 per cent whereas a concentration of 1 mg of the extract produced 100 per cent inhibition. The extract (5-100 micrograms) produced 20 +/- 4 to 91 +/- 16 per cent enhancement of [3H]flunitrazepam binding. In functional studies using 36Cl-influx assay in mammalian spinal cord neurons, W. somnifera root extract increased 36Cl-influx in the absence of GABA. This effect on 36Cl-influx was blocked by bicuculline and picrotoxin; and enhanced by diazepam. These results suggest that the W. somnifera extract contains an ingredient which has a GABA-mimetic activity.Item Plasmacytoma of maxilla.(1993-07-01) Chamyal, P C; Mehta, A KItem Relaxant effects of adenosine & ATP on rat caecum-appendix.(1982-08-01) Mehta, A K; Kulkarni, S KItem Utility of two-dimensional echocardiography in the detection of left ventricular intracavitary mass.(1985-03-01) Mehta, A K; Sharma, S; Daruwala, D F; Desai, A G; Hansoti, R C
