homogeneous immunoglobulins in the serum of irradiated and bone marrow reconstituted mice: the role of thymus and spleen.the influence of thymectomy and splenectomy on the frequency and class distribution of homogeneous immunoglobulins (h-ig) in serum was studied in lethally irradiated (dba/2 x c57bl/rij)f1 mice reconstituted with syngeneic bone marrow. during four follow-up periods in the first 9 months after transplantation, the sham-operated controls and splenectomized animals developed transient h-ig in an average frequency of 14.2 and 15.7% respectively. there were no marked differences in the incidence of h- ...2004387578
different effects of the ionophore a-23187 and d-glucose on 45ca2+ fluxes in isolated islets of ob/ob-mice.fluxes of 45ca2+ were studied in beta-cell rich islets of non-inbred ob/ob-mice, using lacl3 to wash out extra-cellular and superficially bound 45ca2+. the ionophore a-23187 (10 microm) increased the 45ca2+ uptake in islets both at 3 and 20 mm d-glucose, the effect being more pronounced after 10 min than after 120 min of incubation. in incubations for 120 min, 20 mm d-glucose induced a higher uptake of 45ca2+ than did a-23187. the ionophore enhanced the unidirectional efflux of 45ca2+ from prelo ...1986362823
gel filtration of sialoglycoproteins.the role of sialic acid in the gel-filtration behaviour of sialoglycoproteins was investigated by using the separated isoenzymes of purified human liver alpha-l-fucosidase and several other well-known sialic acid-containing glycoproteins (fetuin, alpha1-acid glycoprotein, thyroglobulin and bovine submaxillary mucin). for each glycoprotein studied, gel filtration of its desialylated derivative gave an apparent molecular weights much less than that expected just from removal of sialic acid. for th ...1978356853

action of ethyl and methyl methane sulfonates on dna injection and genetic recombination in t7 bacteriophage.after treatment with methyl or ethyl methane sulfonate, t7 amber mutants display a reduced capacity for recombination. moreover, alkylation reduces recombination frequency involving markers on the right-hand side of the genetic map more than it reduces recombination frequency involving markers on the left-hand side. we interpret this to mean that alkylation can stop dna injection at any point along the dna molecule, and that t7 phage injects its dna in a unique fashion starting from the end carr ...1992183007
avian leukosis viruses of different subgroups and types isolated after passage of rous sarcoma virus-rous-associated virus-0 in cells from different ring-necked pheasant embryos.avian leukosis viruses of subgroups a and f (rav-a and rav-f) arose at a low rate after passage of rous sarcoma virus-rous-associated virus-0, which is subgroup e, in cells from ring-necked pheasant embryos. in cells of two embryos, all of the viruses isolated after virus passage were rav-f. however, in cells of a third embryo, both rav-a and rav-f were isolated. in addition, there sometimes were type-specific differences among the different isolates of rav-a and rav-f from the cells of single e ...1976183006
some biological properties of human chorionic follicle stimulating hormone.the biological properties of human chorionic fsh (hcfsh) for rat ovaries were investigated. highly purified hcfsh had similar response to the ovarian augmentation test as bovine fsh and significantly enhanced 3h-thymidine uptake by granulosa cells and theca cells in the ovary of hypophysectomized rat. in contrast, highly purified hcg little responded to the ovarian augmentation test and had no effect on 3h-thymidine uptake by the ovary. these results indicate that hcfsh may promote the follicula ...1975182476
[role of alimentary hyperglycemia in the pathogenesis of several disorders of lipid metabolism].alimentary hyperglycemia in rabbits was found to be accompanied by increase in cholesterol level, as well as in the amount of triglycerides in the blood sera. progressive increase in the serum concentration of pre-beta lipoproteids (serving as endogenous tryglyceride carrier) has also been demonstrated. a short-term feeding with cholesterol against the background of hyperglycemia in rabbits appeared to result in early marked atherosclerotic changes, as compared to those in control group of normo ...1976182301
