| demonstration of a murine cell surface component with affinity for exogenous beta 2-microglobulin. | murine and human beta 2-microglobulin (beta 2m) bind to various types of mouse cells. the binding is saturable and displays a single association constant of about 1 x 10(9) liter/mol. the binding of beta 2m to splenocytes was not affected by a variety of metabolic inhibitors but was temperature-dependent. it is suggested that the beta 2m "receptor" exhibits a temperature-dependent conformational change since the "receptor", whether integrated into the membrane or solubilized by the detergent tri ... | 1979 | 95108 |

| leukotrienes increase glucose and lactate output and decrease flow in perfused rat liver. | in isolated perfused rat liver leukotriene c4 and d4 but not b4 and e4 enhanced glucose and lactate output and lowered perfusion flow similar to the thromboxane a2 analogue u46619, extracellular atp and prostaglandin f2 alpha. the kinetics of the metabolic changes caused by leukotriene c4 and d4 resembled those effected by u46619 and atp but not those elicited by prostaglandin f2 alpha; the kinetics of the hemodynamic changes were similar only to those caused by u46619. the results show that leu ... | 1988 | 2831885 |
| increased gastric cholinergic activity evoked by 5-hydroxy-l-tryptophan in the rat. | in gastrointestinal tissues such as rat stomach, exogenous 5-hydroxytryptamine (5ht) has little or no ability to affect nerve activity. however, endogenous 5ht might act differently, and this was investigated by stimulating 5ht synthesis using 5-hydroxy-l-tryptophan (5htp). in longitudinal strips of rat forestomach, 5htp (50 and 500 microm) increased cholinergically mediated contractions evoked by electrical field stimulation, probably by facilitating acetylcholine release; contractions evoked b ... | 1986 | 3019729 |
| gene-specific differences in the aflatoxin b1 adduction of chicken erythrocyte chromatin. | mature and immature chicken erythrocyte nuclei were treated with activated aflatoxin b1 (2,3-dichloroaflatoxin b1), producing covalently bound dna adducts. this reaction produces alkali-labile sites in the dna which can be identified by using a variation of the maxam-gilbert sequencing procedure. we determined the aflatoxin b1 accessibility of defined regions of the erythroid genome by using different specific probes and monitoring the disappearance of similar-sized fragments generated by restri ... | 1988 | 3142684 |
| fodrin is part of a filamentous cortical sheath of the detergent resistant cytoskeleton of cultured cells before and after cytochalasin treatment. | cytoskeletons of cultured cells prepared under mild conditions in the presence of "stabilization' buffer contain most of the fodrin present in the cells. the fodrin in these cytoskeletons was localized by immunofluorescence microscopy and found to be present in a cortical sheath of fine filaments. in general, the filamentous distribution showed no correspondence with actin bundles as revealed by double-label fluorescence microscopy. however, in cells with large and abundant stress fibers, some c ... | 1986 | 3514218 |
| intracoronary naloxone in hemorrhagic shock: dose-dependent stereospecific effects. | treatment with naloxone improves cardiovascular function and survival in a variety of shock models, and numerous sites and mechanisms for its action have been proposed. data presented in this article support the hypothesis that in hemorrhagic shock naloxone exerts its beneficial hemodynamic effects by acting primarily at cardiac opiate receptors. naloxone or its stereoisomer (d-naloxone) were administered intravenously (iv) and directly into the coronary circulation (ic) in dogs anesthetized wit ... | 1985 | 4025562 |

| the detection of a viral interfering substance in the shope papilloma and the vx7 and vx2 carcinomas. | in vivo assay of shope papilloma protein extract and in vitro assay of extracts from shope papilloma, vx7 and vx2 carcinomas showed strong interferon-like activity in the papilloma and moderate activity in the carcinomas. the interpretation is that the presence of viral nucleic acid in all three tumors stimulated the production of this substance even though fluorescent antibody studies reveal the protein coat only in the papilloma and vx7. | 1967 | 4863135 |
