| mao inhibition and the effects of centrally administered lsd, serotonin, and 5-methoxytryptamine on the conditioned avoidance response in rats. | pretreatment with the mao-inhibitors iproniazid, clorgyline, or deprenyl abolishes the effects of lsd on the conditioned avoidance response (car) in rats. the effects of serotonin (5-ht) and 5-methoxytryptamine (5-mt) are greatly potentiated by these substances. brain levels of lsd are not affected by mao inhibition whereas levels of 5-ht and 5-mt are significantly elevated. it is postulated that the decreased behavioral response to lsd is the result of 'mao inhibitor-induced' changes whereas th ... | 1979 | 108709 |
| mutual antagonism of behavioral effects of trh and thiobarbiturate on an operant task in rhesus monkeys. | similar excitatory or depressant response rate dependent effects on monkeys responding on a variable interval reinforcement schedule were observed following intravenous administration of either thyrotropin releasing hormone (trh) or thiobarbiturate. however, these agents were mutally antagonistic when given together even though the response rate altering effects of each agent were in the same direction. these findings establish an additional behavioral effect of exogenously administered trh in p ... | 1979 | 108712 |
| biochemical and serological studies on pasteurella multocida isolated from cattle in the sudan. | of 42 strains of pasteurella meltocida isolated from different outbreaks of hemorrhagic septicaemia and from healthy cattle in various parts of the suden, 38 belonged to carters' type b and four to type e. the strain used for vaccine production was type e. with respect to somatic antigen determination, there was some correlation between the results of the gel diffusion and the agglutination tests as most strains reacted with 0 groups 6 antisera in both tests. however, some antigens cross-reacted ... | 1979 | 110516 |

| double antibody specificity of lymphoid cells isolated from normal human intestinal mucosa. | lymphoid cells were isolated from normal human mucosal specimens. a certain fraction of these cells exhibited double antibody specificities at the levels of both light kappa and lambda chains and heavy mu and gamma chains. the variable frequency with which these cells were detected appears to be a characteristic of this population. they represent a very low proportion of the total number of cells isolated. | 1979 | 114243 |
| pharmacological modification of experimental tardive dyskinesia. | cebus apella monkeys subjected to chronic haloperidol administration develop neurologic disturbances very similar to neuroleptic-induced acute dystonia human beings. after varying lengths of time, certain monkeys develop a prolonged dyskinetic syndrome resembling tardive dyskinesia (td), as seen clinically. two monkeys with signs of td were given single intramuscular injections of various compounds with known effects on the catecholaminergic, cholinergic, serotoninergic and gaba-ergic neurotrans ... | 1979 | 115227 |
| study of the anti-tumor effect of polypeptide pineal extract. | bovine pineal polypeptide extract (ppe) exerted an anti-tumor effect on mouse-transplantable tumors: mammary cancer (rsm), squamous cell cervical carcinoma (scc), hepatoma-22a and lympholeukemia lio-1, and had no effect on harding-passey melanoma and leukemia l-1210. it was shown that ppe possessed the ability to decrease the incidence of dmba-induced mammary adenocarcinomas in rats. the daily administration of 0.5 mg ppe prolonged the life span of rats by 25% and failed to influence spontaneous ... | 1979 | 117414 |
| in vitro response to rosette inhibition factor (rif) and rosette restoring factor (rrf) of human lymphocyte after fractionation on a discontinuous density albumin gradient. | in vitro studies on peripheral blood lymphocytes from tuberculous patients and healthy subjects are reported. factors isolated from human serum used in the experiments included the rosette inhibition factor (rif) from serum of tuberculous patients and the rosette restoring factor (rrf) from serum of healthy subjects. lymphocytes were fractionated on a discontinuous bsa gradient. lymphocytes from healthy subjects, sensitive to rif, as well as lymphocytes from tuberculous patients, sensitive to rr ... | 1979 | 117785 |
| comparison of pasteurella multocida serotyping systems. | thirty-two type specific cultures used in four typing systems for serologically classifying pasteurella multocida were compared as originally described for: (1) little and lyon's plate agglutination test; (2) carter's indirect hemagglutination test, hyaluronidase decapsulation test, and acriflavine reaction; (3) namioka's plate and tube agglutination tests; and (4) heddleston's gel diffusion precipitin test. in addition, seven cultures from robert's five passive protection groups were included. ... | 1979 | 118694 |
| serotyping of pasteurella multocida isolants from poultry. | a total of 607 pasteurella multocida strains were isolated in israel from turkeys, geese, and chickens. serotyping was carried out by the gel-diffusion precipitin test. the antigens were heat-stable saline extracts of the organisms, and the diagnostic sera were produced in chickens using formalinized bacterins. among 31 serotypes containing one to five antigenic factors, serotypes 1 and 3 accounted for 58.1%, 80.8%, and 88.9% isolants from turkeys, geese, and chickens, respectively. on the basis ... | 1979 | 118742 |
| methionine transport in pseudomonas aeruginosa. | a high-affinity (km = 2.7 x 10(-7) m) energy-requiring methionine-transport system has been characterized in rm 46 and rm 48, two different pao methionine auxotrophs of pseudomonas aeruginosa. after 8 s of transport 40--60% of the methionine label in the alcohol extract appears in s-adenosyl-l-methionine (sam) with the remaining activity in free methionine. methionine transport required a high degree of structural specificity for transport. stimulation of transport occurred by addition of glucos ... | 1979 | 120222 |

| [decarboxylase activity study of pasteurella multocida]. | ornithine-, lysine- and arginine-decarboxylase activity of 218 p. multocida strains, isolated from birds of varying disease symptoms in bulgaria and cssr, and from pigs, rabbits and birds in cuba, ussr and cssr, was studied after the method of moller. positive ornithine decarboxylase activity was established in 211 strains, low -- in 2, and negative -- in 5 strains. low arginine decarboxylase activity was observed in 12 pasteurella strains, while in 14 -- low lysine decarboxylase activity. the p ... | 1979 | 120631 |
| [effects of caudate nucleus stimulations on the primary and secondary endings activity of soleus muscle spindle]. | effects of repetitive stimulation of the contralateral caudate nucleus on the static discharge and dynamic sensitivity of soleus muscle spindle primary and secondary endings were studied in cats anaesthetized with halothane (fluothane). by progressive increasing the depth of anaesthesia two different fusimotor effects could be observed. 1. a static facilitatory effect; under light anaesthesia the static discharge of primary and secondary endings were strongly increased. the response of the prima ... | 1975 | 123860 |
| fatal immune complex glomerulonephritis without deposits. | repeated intravenous injections of egg albumin in rabbits produced small antigen-excess complexes and severe glomerulonephritis. immunoglobulins and complement in the glomeruli were not clearly demonstrated by immunofluorescence; deposits were found to be sparse by electron microscopy. this study demonstrates that soluble immune complexes are responsible for the glomerular reaction. the apparent absence of deposits is thus not sufficient to exclude an immune complex pathogenesis. | 1975 | 123971 |
