Acute heat stress in growing rats: effect on small intestinal morphometry and in vivo absorption
(1993) A. Sengupta; R.K. Sharma
1. 1.|Young growing rats (35-45 g) were exposed to high ambient temperature (37 ± 1°C) for 24 h, while the controls were kept at 24 ± 2°C. 2. 2.|Quantitative morphometry based on stereological principle and absorptive studies by an in vivo method were performed to evaluate the structural and functional adaptations of the small intestine in rats exposed to heat. 3. 3.|The effect of heat stress on various morphometric dimensions of the small intestine shows significant reduction in dry weight, villus height, villus surface area, crypt depth, while the absorptive study shows, significant decrease in absorption per unit dry weight, unit length and unit villus surface area of the small intestine as compared to the control. 4. 4.|This adaptive alteration in the structure and function of the small intestine indicates the change in the mucosal dynamics of gut epithelium in heat stress. © 1993.
Chemical investigation of the seed fat of Celastrus paniculatus
(1970) A. Sengupta; H.N. Bhargava
The fatty acid composition of the seed fat of Celastrus paniculatus was determined by spectrophotometry, urea adduct formation and quantitative paper chromatography. The percentages of individual acids were found to be: formic, 1.5; acetic, traces; benzoic, 3.4; palmitic, 31.2; stearic, 3.5; oleic, 22.5; linoleic, 15.7; and linolenic, 22.2. A solid ester (m.p. 60–62°c), isolated from the seed fat, has been partly characterised by chromatography and spectral analysis. Copyright © 1970 John Wiley & Sons, Ltd
Investigation of glycopyrrolate as a premedicant drug
(Oxford University Press, 1980) A. Sengupta; P.K. Gupta; K. Pandey
The clinical efficacy of glycopyrrolate, a synthetic anticholinergic drug, for premedication was compared in a double-blind study with that of atropine or hyoscine in patients anaesthetized with diethyl ether. The antisialogogue actions of the three drugs were similar. Glycopyrrolate produced less tachycardia, pyrexia and blurred vision than atropine, and its sedative effect was less than that of hyoscine. © 1980 Macmillan Journals Ltd.
Studies on the Seed Fat Composition of Moringaceae family
(1970) A. Sengupta; M.P. Gupta
The component fatty acids of the seed fats of Moringa pterygosperma and Moringa concanensis have been investigated by using the techniques of urea‐adduct segregation and quantitative paper chromatography. The present analysis indicates the percentage composition of the mixed fatty acids to be: palmitic 3.1, 11.7; stearic 8.0, 3.8; arachidic 7.8, 2.4; behenic 3.5, 4.1; lignoceric 5.8, 0.6; oleic 71.0, 75.5 and linoleic 0.8, 0.9% respectively.
