lysozyme synthesis by established human and murine histiocytic lymphoma cell lines.	a human cell line established in culture from a histiocytic lymphoma patient synthesizes and secretes the monocyte-granulocyte specific enzyme lysozyme. 18 other human cell lines with characteristics of t-lymphocyte, b-lymphocyte, burkitt's lymphoma, non-burkitt's lymphoma, myeloma, and bone marrow epithelial cells were not associated with lysozyme. among murine cell lines, lysozyme was produced by (a) three histiocytic lymphoma or macrophage lines, which mediate antibody-dependent phagocytosis ...	1976	1083890
cell-mediated immunity: delayed-type hypersensitivity and cytotoxic responses are mediated by different t-cell subclasses.	cell-mediated immunity includes both the generation of cytotoxic cells and initiation of delayed-type hypersensitivity (dth). the resting t-cell population, before stimulation by antigen, already contains cells of the lyl subclass that are programmed to initiate dth (and helper function) but not cytotoxic responses, as well as ly23 cells which can generate killer activity (and suppressive function) but not dth. the central implication of these findings is that the broad division between humoral ...	2001	1083891

antimicrobial resistance of shigellae isolated in michigan.	patterns of antimicrobial resistance were studied for 213 strains of shigellae isolated in rural and urban areas of michigan by quantitative techniques: 66% of these organisms were resistant to ampicillin, tetracycline, cephalexin, or chloramphenicol or had multiple resistance to various combinations of these antibiotics. the incidence of resistant organisms was higher in the detroit-wayne county area, which is the most urban part of the state. nalidixic acid and oxolinic acid were noted to be q ...	1975	1089819
observations on the serologic changes in the recombinants in shigella flexneri serotype 4a.	studies on the antigenic composition of 84 diagnostic strains of s. flexneri serotype 4a and their lac+ recombinants from a cross with e. coli hfrc were carried out. considerable differentiation of agglutination reaction was found both in original material and in recombinants. an interesting group included recombinants which completely lost their capability to agglutinate with sera specific for type and group antigens and preserved only the capability to agglutinate in the polyvalent serum of s. ...	1975	1090112
pathophysiology of shigella diarrhea in the rhesus monkey: intestinal transport, morphological, and bacteriological studies.	in contrast to the "toxigenic diarrheas" caused by vibrio cholerae and escherichia coli, the site and mechanism of fluid loss in shigellosis are unknown. the occurrence of watery diarrhea in shigellosis suggests involvement of the small bowel. therefore, jejunal, ileal, and colonic water and electrolyte transport was studied in shigella flexneri 2a-infected monkeys. infected animals fell into three groups: dysentery alone, diarrhea alone, or diarrhea and dysentery. in controls, net water, sodium ...	1975	1090480
occurrence of the bacteriophage lambda receptor in some enterobacteriaceae.	in escherichia coli k-12, the receptor for phage lambda is an outer membrane protein which inactivates the phage in vitro. lambda receptor activity was found in extracts from all wild strains of e. coli tested, although most of them fail to support growth of the phage. in some cases this failure is due to a masking of the receptor in vivo, the bacteria being unable to adsorb the phage or to react with antireceptor antibodies. in other cases, adsorption does occur, and the nature of the block in ...	1975	1090748

studies on the energetic metabolism of shigella flexneri and escherichia coli hybrids devoid of penetration ability. ii. oxygen uptake and dehydrogenase activity.	oxygen uptake and dehydrogenase activity are studied with lac+ kcpminus hybrids of shigella flexneri, being avirulent to the eyes of guinea pigs, because of having lost ability for penetration in epithelial cells. these strains were obtained by hybridization of the virulent strain shigella flexneri 222 5 a with the hfr strain escherichia coli k-12 p4x. it is established that lac+ kcp minus hybrids are characterized by significant decrease of respiratory activity. this decrease is outlined as a t ...	1975	1098322
[the anodic-moving thermolabile antigen (ata) of gram-negative bacteria: its occurrence in rough mutants of shigella flexneri and escherichia coli(author's transl)].	the thermolabile antigen (ata) moving to the anode, discovered by us (9) and also described by larsson et al. (8), could be detected in ra-, rb-, re- and rd-mutants of sh. flexneri and, in smaller amounts, in rd- and re- mutants of e. coli o8:k27:h. so it proves to be different from kunin's common antigen (7). our results lead to the conclusion that ata is located in a more inner part of the bacterial cell wall and is fixed by noncovalent linkages.	1975	1098323

acetanilides: effects on invertebrate neurons correlated with analgesic activity in vertebrates.	identified neurons in the buccal ganglion of the marine mollusc navanax inermis were used to examine the effects of acetanilides on neuronal membrane properties. acetanilides increased the membrane potential and conductance of these neurons in a dose-dependent, reversible manner. these events would have the effect of decreasing membrane excitability. acetanilides increased the slope of the curve of membrane potential as a function of log [k+]o from 33 to 58 mv decade change in [k+]o and decrease ...	2005	1151738
pentobarbital pharmacokinetics in the normal and in the hepatectomized rat.	the pharmacokinetics of pentobarbital, a barbiturate metabolized by the liver, was compared in normal and in hepatectomized rats. the blood concentration time curve following a single intravenous injection of pentobarbital was fitted to a two-compartment open model. both the volume of the central compartment and the elimination rate constant were significantly reduced in hepatectomized rats. it is concluded that the liver plays a role both in the metabolism and the distribution of pentobarbital.	1975	1151743
a study of absorption of compounds from the rat biliary tree by retrograde intrabiliary injection (rii).	absorption of compounds from the biliary tree of rats was studied by a retrograde intrabiliary injection (rii) technique. after rii of a number of compounds in volumes that exceeded the maximum distended capacity of the biliary tree, only that volume of rii solution which corresponded to biliary tree capacity remained therein. furthermore, this latter portion of rii solution was absorbed by a first-order process when the duration of bile duct cannula occlusion was extended. thus, the present stu ...	1975	1151745
effects of sodium acetylsalicylate on body temperature of monkeys under heat exposure.	exposure of taiwan monkeys to 38 degrees c ambient temperature caused: a) raised body temperature, b) restlessness and struggling, c) increased evaporative heat loss and d) increase in tail skin temperature. after the administration of sodium acetylsalicylate, 100 to 250 mg/kg intraperitoneally or 4 to 15 mg intracerebroventricularly (third ventricle) the same heat load caused: a) less increase in body temperature, b) no restlessness or struggling, c) an initially higher rate of evaporative heat ...	1975	1151748
intracellular recordings of rod responses during dark-adaptation.	1. dark-adaptation of rod photoreceptors has been studied in the isolated axolotl (ambystoma mexicanum) retina by intracellular recordings. rod responsiveness was greatly reduced immediately after a 30 sec partial bleach, but partially recovered with time in the dark. 2. in parallel spectrophotometric measurements using isolated retinas, regeneration of the rod pigment could not be detected after a 30 sec bleach. 3. during rod dark-adaptation, the response of a rod to a given stimulus increased ...	2005	1151778
