[antibacterial immunity in diphtheria. experimental research].	a number of 700 guinea pigs were immunized by parenteral route with non-toxigenic corynebacterium diphtheriae strains, then inoculated with various doses of homologous and heterologous toxigenic c. diphitheriae strains. the results showed that non-toxigenic c. diphtheriae strains confer a certain degree of protection when the challenge is done with homologous toxigenous strains, especially when not more than 500 million germs/ml are used for the challenge dose. this suggests that the carriage of ...	1979	111333
subsets of t lymphocytes and lymphocyte cooperation. modulation of the immunocellular response.	recent advances in the characterization of t cell subsets suggests that the various subsets of t cells described in mice also occur in man. these various subsets of t cells can be detected by the use of appropriated antisera, co-cultivation of purified lymphoid cell preparations and differential sensitivity to radiation. clinical applications from these new observations are now underway and it is hopeful that they should help to achieve a better understanding of the mechanisms responsible for au ...	1979	111313
arthrosonography: gray-scale ultrasound evaluation of the shoulder.	gray-scale ultrasound images of the shoulders of 6 rhesus monkeys were obtained before and after fluid instillation to assess the ability of ultrasound to diagnose joint disorders. the normal bony landmarks and muscular structures were shown. after the fluid was introduced, fluid collections were identified in the axillary pouch and subscapular bursa. ultrasound is a promising new method of detecting intra-articular effusions of the shoulder.	1979	111302
plasma levels of d-amphetamine in hyperactive children. serial behavior and motor responses.	amphetamine has been clearly documented to be an efficacious treatment for hyperactive children. the pharmacokinetics of amphetamine have been studied in adults, but not in children. sixteen male children who scored greater than 2sd from norms on factors i and iv of conner's teacher rating scale and who were not excluded for reasons to do with medical or psychiatric conditions, intelligence, or age, had a plasma d-amphetamine apparent elimination half-life of 6.8 +/- 0.5h. peak plasma level occu ...	2000	111276
comparative behavioral effects of clorgyline and pargyline in man: a preliminary evaluation.	the antidepressant and other behavioral effects of clorgyline, a preferential inhibitor of monoamine oxidase (mao) type a, were compared with those of pargyline, a preferential inhibitor of mao type b, in 16 depressed patients. in a subgroup of more severely depressed patients, clorgyline treatment for 4 weeks resulted in significant improvement on both observer-rated and self-rated scales, while minimal changes occurred during pargyline treatment. similarly, in a crossover study that included 8 ...	1979	111274
[determination of serum digitoxin by means of a solid-phase enzyme-linked immunosorbent assay (author's transl)].	a solid-phase elisa-technique for clinical applications is described. it requires little apparatus other than a photometer and allows the rapid determination of serum digitoxin levels. it differs from the original technique only in the sample volume being smaller and a digitoxin calibration curve being required. concurrent assays by a reference method (86rb-erythrocyte assay) gave results in excellent agreement with the values obtained by the modified elisa-technique on samples from patients und ...	2000	111013
nasogastric intubation technique for bile sampling in the baboon (papio ursinus).	a duodenal tube was introduced into the duodenum of the fasted baboon via the nasal passage. after the application of vacuum for several minutes, the baboon received an intravenous injection of pancreozymin and cholecystokinin which caused contraction of the gall bladder. aspiration of the bile sample was carried out via the duodenal tube.	2000	110980

cardiac imaging with tantalum-178.	tantalum-178 is a potential tracer for the first transit studies of the heart. it has a short physical half-life (9.3 minutes) and is obtained as a generator product from its long-lived (21.3 days) parent, tungsten-178. first transit studies were performed in the monkey and dog following the intravenous injection of 20 mci (740 mbq) of tantalum-178. imaging was performed with a large field of view single crystal camera and a multicrystal camera. pulmonary dilution curves were derived for the ana ...	1979	108764
treatment of prolactin-secreting pituitary tumours in young women by needle implantation of radioactive yttrium.	twenty-one young female patients are described who presented with amenorrhoea, galactorrhoea or infertility, and were treated by 90y pituitary implantation of 20,000 rads. there was no morbidity. in all patients serum prolactin values were elevated and radiographs of the pituitary fossa were abnormal. observations are available for 1--76 months (mean 27) after implantation. the median fall in prolactin values was 60 per cent while there was no deterioration in pituitary function if normal pre-op ...	1998	108759
comparison of the discriminative stimulus properties of nefopam and morphine.	separate groups of rats were trained to discriminate nefopam or morphine from saline in a two-lever operant task. nefopam produced saline-appropriate responding in morphine-trained rats. the highest dose of morphine tested in nefopam-trained rats produced responding appropriate for neither training treatment. this intermediate morphine responding was antagonized by a naloxone treatment that had no effect on the nefopam discrimination. these results suggest that the stimulus properties of nefopam ...	1979	108741
enhanced 5-hydroxytryptamine-mediated behavioural responses in rats following repeated electroconvulsive shock: relevance to the mechanism of the antidepressive effect of electroconvulsive therapy.	treatment of rats with one electroconvulsive shock (ecs) per day for 10 days enhanced the hyperactivity syndrome produced by administration of tranylcypromine (10 mg kg-1) and l-tryptophan (50 mg kg-1) given 24 h after the final shock. similar enhancement was seen whether the shock was alternating sinusoidal or direct current (fractionated), whether it was given through unilaterally or bilaterally placed electrodes and whether or not a neuromuscular blocking agent (fazadinium) was used. five sho ...	1979	108733
dietary modification of amphetamine stereotyped behaviour: the action of tryptophan, methionine, and lysine.	rats fed diets high in tryptophan, methionine, and tryptophan plus methionine or lysine were subsequently injected with 10 mg/kg d-amphetamine. the amount of amphetamine-induced stereotyped behaviour observed varied as a function of the dietary addition, with methionine showing the greatest difference to controls, and lysine the least. whole brain catecholamine levels and 5-hydroxytryptamine levels also showed amino acid-specific changes.	1979	108724
sex differences in behavioral and thermal responses to pargyline and tryptophan.	the effects of parenterally injected pargyline and tryptophan on rectal temperature and behavior have been studied in male and female rats. pargyline alone (50 mg/kg) produced hypothermia in both sexes. pargyline (50 mg/kg) followed by low doses (20--50 mg/kg) of tryptophan caused a behavioral syndrome consisting of tremor, hindlimb abduction, forepaw treading, and straub tail. in females, but not in males, hypothermia was potentiated. the same dose of pargyline followed by higher doses (60--150 ...	1979	108723
piracetam facilitates retrieval but does not impair extinction of bar-pressing in rats.	rats were trained on a continuously reinforced bar-press response for water reward. seven days later they were retested for retention, with or without pretest injection of the nootropic drug, piracetam. drug-treated animals had significantly shorter response latencies than saline-treated animals. the results are interpreted as a facilitation of retrieval processes after forgetting. the experiment was extended under extinction conditions and it was found that after three sessions there was a tend ...	1979	108722
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 ...	1979	108707
