Isoenzymes are very suitable markers for the study of the inter-breed diversity of the silkworm Bombyx mori L. (Lepidoptera: Bombycidae). More than 250 breeds are raised in Bulgaria, which are not very well studied with regard to their isoenzymic polymorphism. Polymorphism of nonspecific esterases from pupal haemolymph was analyzed, as well as of phosphoglucomutase from different organs of larv...

Cultures of marrow mononuclear cells were exposed to medium derived from cell cultures infected with several different strains of human herpesvirus-6 (HHV-6) immediately before the addition of either of two growth factors, granulocyte-macrophage colony-stimulating factor and interleukin-3. Exposure to any of the viral preparations suppressed the outgrowth of nonspecific esterase-positive adhere...

Resistance to the organophosphates (OP) temephos, malathion, and pirimiphos methyl, and the carbamate propoxur was found to be low (< 5-fold) in 3 Aedes aegypti populations collected from Falcon and Aragua states of Venezuela. Resistance to chlorpyrifos (OP), permethrin, and lambda-cyhalothrin (pyrethroids) was moderate (7-fold) in both populations. Mechanisms of resistance were investigated wi...

Recent work in our laboratory with mouse radiation chimeras suggests that the macrophage type of synovial lining cell is derived from bone marrow. Further evidence for including this cell type in he mononuclear phagocyte system is now presented. Rosette formation with IgG coated sheep red cells, immunofluorescent staining for surface Ia antigens, and nonspecific esterase staining all show the p...

The present study defines the early response of normal rabbits to the intravenous injection of a single, sublethal dose of endotoxin. Within the first few hours following endotoxin there occurs in the circulating plasma of recipients a decrease in ionized calcium, a threefold increase in the heat-stable, organo-phosphate-resistant esterase level, and a striking increase in the endotoxin-detoxif...
