Comparative evaluation of enzyme immunoassays based on synthetic glycoconjugates and phenolic glycolipid-I for immunodiagnosis of leprosy.

Enzyme immunoassays (EIAs) based on synthetic glycoconjugates containing the terminal monosaccharide (M-BGG) or disaccharide (ND-BSA) residue of the trisaccharide component of phenolic glycolipid-I (PGL-I), for immunodiagnosis of leprosy are described. The results of the assays were compared with that of the EIA using PGL-I. All the three assays were highly specific for leprosy. The per cent positivity of active lepromatous leprosy (LL) patients with M-BGG was 78.05 in comparison to 85.36 with ND-BSA and 82.11 with PGL-I. Similarly, the positivity of tuberculoid (TT) leprosy patients in M-BGG assay was lower than that in EIAs using ND-BSA or PGL-I. However, the difference in the positivity of individual category of leprosy patients in the three EIAs was not statistically significant. The correlation between absorbance values of leprosy sera in EIAs based on M-BGG and PGL-I, as well as that in assays using ND-BSA and PGL-I was statistically significant.

Effect of centrally administered glucagon on blood lipids in anesthetised dogs.

Previously we have proposed the existence of the central glucagon sensitive receptors in dogs. The present study was undertaken to explore the role of centrally administered glucagon on lipids in view of the proposed theory that the hypothalamic lipomobilizing centres are sensitive to glucose or substances that affect glucose metabolism. Glucagon (0.01 microgram) administered through the intracerebroventricular (ICV) route in anesthetised mongrel dogs, caused hypolipidemia (P greater than 0.001), hypocholesterolemia (P greater than 0.001), decreased blood free fatty acid (P greater than 0.001) and triglycerides (P greater than 0.001) levels; but increased blood high density lipoprotein (P greater than 0.01) level at 30 min. These effects on the central administration of glucagon, were not observed in pancreatectomised animals and spinal cord transectomised animals. Therefore, we conclude that the lipolysis on the central administration of glucagon, is caused by the endogenous glucagon secreted from the pancreas through the sympathetic fibers.
