Item Cardiac dysautonomia in lepromatous leprosy.(1984-07-01) Kale, H D; Zawar, P C; Chawhan, R N; Kulkarni, G RCardiovascular autonomic functions were studied in 32 patients of lepromatous leprosy, including 12 patients of lepra reaction. Fifty age and sex matched healthy subjects served as controls. Variable degree of autonomic dysfunction was observed in the study group. The derangement of autonomic functions in patients of leprosy can be explained on the basis of neurotrophic action of lepra bacilli that infiltrate the sympathetic and the parasympathetic fibres.Item Extracellular electrical activity from the photoreceptors of midge.(2004-09-24) Babrekar, A A; Kulkarni, G R; Nath, B B; Vidyasagar, P BThe ontogeny of photosensitivity has been studied in a holometabolous insect, the midge Chironomus ramosus. The life cycle of midges shifts from an aquatic environment to a non-aquatic environment. Extracellular electrical activity of photoreceptor organs was recorded at larval and adult stages. We found an increase in photosensitivity as the larva metamorphosed to the adult stage. This is the first report of changes in photosensitivity during the development of any insect described in an ecological context.Item In vitro inhibition of phospholipid synthesis by cyclic 3'-5'-adenosine monophosphate in chicken liver slices.(1979-10-01) Bhat, N R; Rao, A M; Kulkarni, G R; Murthy, S KItem Induction of choline-ethanolamine kinase in chicken liver by 17-beta-estradiol.(1986-10-01) Kulkarni, G R; Murthy, S KItem Purification of choline-ethanolamine kinase from chicken liver and its regulation by cAMP.(1986-04-01) Kulkarni, G R; Murthy, S KItem Studies on the inhibition a fatty acid synthesis in the chicken liver by adenine compounds in vitro.(1979-12) Bhat, N R; Kulkarni, G R; Rao, A Madhava; Murthy, S KThe biosynthesis of fatty acids from [1-14C]-acetate in the chicken liver slices in vitro was inhibited by cAMP, adenosine, 5'-AMP, 3'-AMP, ATP, NAD and FAD but not by adenine, guanine or inosine. The minimum structural requirement for inhibition appears to be adenosine. The inhibitory action of adenosine, 5'-AMP and NAD on fatty acid synthesis is likely to be mediated by adenosine or its metabolites since adenosine deaminase reverses the inhibition while it has no effect on the inhibition by cAMP; thus, the inhibitory effect of cAMP is probably not mediated through its hydrolysis products, 5'-AMP, or adenosine.
