synthetic antigens iii. antigen-binding cells to interpolymer of styrene and maleic acid psm and sheep red blood cells in mice immunized with psm.studies on the immune response in mice to a new synthetic antigen interpolymer of styrene and maleic acid (psm) are described. the immune response was measured by determination of antigen binding cells by means of rosette test with psm-coated srbc, an unexpected effect was observed--besides rosette-forming cells for psm, rosette-forming cells and agglutinating antibodies for sheep red cells were found. the results presented in this paper suggest that psm is acting both as an immunogen and a poly ...197994989
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 ...1979115227
the effects of alcohol on agonistic behavior in the telomian dog.the study analyzed the effects of alcohol on agonistic behavior in three independent social systems, each compromised of two male and one female telomian dog. three dose levels were used: 0, 0.8, and 1.6 g/kg body weight of absolute alcohol diluted to 20%. observations were made when none, one (top, middle or low ranking), or all dogs in a system received a given treatment. at the 0.8 g/kg level, low ranking dogs showed an increased frequency of attacks and bone possession time, while top and mi ...1979108707
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 ...1979108709
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.1979114243

a microtiter agglutination test for anti-pasteurella multocida antibodies in turkeys.a microtiter agglutination test (mta) was developed for assaying anti-pasteurella multocida antibodies in turkeys vaccinated with live avirulent clemson university (cu) strain. safranine-o was incorporated with the decapsulated p. multocida antigen and greaterly enhanced the visibility of the sedimented free antigen, which formed a compact red button on the bottom of the well. the advantages of the mta test over the tube agglutination test were that: 1) less antigen and serum were required; 2) d ...1979546401
fowl cholera: cross-protection induced by pasteurella multocida separated from infected turkey blood.crude liver homogenates from turkeys that died of fowl cholera produced by serotype 1 or 3 pasteurella multocida induced cross-protection. pasteurella multocida harvested from the blood of infected turkeys by a centrifugal technique were as immunogenic as the liver homogenates. neither bacterial cell-free blood plasma nor washed p. multocida from infected turkeys induced significant cross-protection. blood plasma containing p. multocida induced significant cross-protection. pasteurella multocida ...1979526205
attenuated live fowl cholera vaccine. i. development of vaccine strain m3g of pasteurella multocida.a live cholera vaccine was developed from a virulent avian septicemia strain of pasteurella multocida serotype 1. the virulent parental strain was mutagenized with n-methyl-n'-nitro-n-nitroso guanidine. mutants were selected that had either smaller colonies at 37 c or temperature sensitivity for growth at 41 c. four small-colony mutants and 2 temperature-sensitive mutants were studied. all the mutants were avirulent for turkeys. sixteen days after turkeys were vaccinated with each mutant, both t ...1979546409
attenutated live fowl cholera vaccine. iii. laboratory and field vaccination trials in turkeys and chickens.administered via the drinking water, m-3-g, an attenuated strain of pasteurella multocida of serotype 1, was found to immunize turkeys and chickens against fowl cholera. immunity was tested by challenging birds intramuscularly, by palatine cleft swab, or orally after 3 vaccinations. no reactions to vaccination were noted in 390 turkeys in 12 laboratory trials, nor in 20,245 vaccinated in field trials. chickens showed no vaccination reactions, and immunity was elicited by challenge in a laborator ...1979546411
the 1978 epornitic of avian cholera on the chesapeake bay.in an outbreak of avian cholera (pasteurella multocida infection) in wildfowl on and around chesapeake bay during march and april of 1978, 31,295 carcasses were retrieved from maryland and virginia. although other birds were involved, mortality was heavy among diving ducks (90% of the total), especially oldsquaw ducks (80% of the total). this is the second outbreak involving primarily diving ducks to be reported from this area of the atlantic flyway. it mimics in many respects the epornitic that ...1979546415
modulation of cross-protection factor(s) of avian pasteurella multocida.cross-protection factor(s) (cpf) of pasteurella multocida were maintained in vitro through at least 9 serial passages. different growth media and temperatures enhanced or repressed the ability of p. multocida to produce cpf. certain amino acids were innoculous to expression of cpf. b-vitamins enhanced cpf, whereas certain inorganic salts repressed cpf. the plasma of normal tuekeys contained a compound or compounds that were responsible for expression and maintenance of cpf.1979546418
