| steroid production by quartered and capsular rat adrenal gland in response to haemorrhage. | 60 min after rapid bleeding (1.5--2.0 per cent of b. w.) both aldosterone and corticosterone production rate by quartered rat adrenals were found to be elevated. however, no difference was observed in the rate of aldosterone and corticosterone production by capsular adrenals of sham operated and hypovolaemic rats. corticosterone production rate by decapsulated adrenals was much more higher after haemorrhage than in the control group. the same alterations could be observed incubating adrenal tiss ... | 1975 | 179800 |
| apparent equilibrium constant between beta-adrenoceptors and a competitive antagonist on a cultured pacemaker cell of mammalian heart. | heart cells from newborn rats and kittens were cultured. in both species the rate of pacemaker activity of single, cultured cells was increased by low concentrations of catecholamines. tthe beta-adrenoceptor blocker (minus)-kl255 antagonized competitively the effects of both, (minus)-noradrenaline and (minus)-isoprenaline. a mean equilibrium constant of 3.6 times 10-10m between (minus)-kl255 and beta-adrenoceptors of single cells was estimated. | 1975 | 235102 |
| new approach to caloric stimulation of the vestibular receptor. | a new caloric testing method is described. during continuous aural irrigation, fluid is switched between hot and cold values at times computed according to a mathematical model of heat conduction in the labyrinth area. as a result, the induced temperature difference across the lateral semicircular canal describes an approximately sinusoidal time course, reaching peak values of equal magnitude but opposite sign. the magnitude of the caloric stimulus may be selected by choosing appropriate irrigat ... | 1975 | 1081359 |
| [studies on the protein and amino acid metabolism of laying hens using 15n labeled casein. 15n concentration in the intestinal content and intestinal tissue in relation to the time of the last 15n administration]. | four laying hens with anus praeternaturalis were fed 15n casein for a period of 6 experimental days. each experimental bird thus received a 15n excess (15n') of 154.44 mg. 11.54 mg of 15n' were found in lysine 3.99 mg in histidine and 9.58 mg in arginine. 2 hens were slaughtered 48 hours after the last 15n dose; another 2 were sacrificed after 144 hrs. in this investigation the n content of the intestinal contents and in the proteins of the small and large intestine were determined. the average ... | 1975 | 1233975 |
| the distribution of serotonin-containing cells in the human alimentary tract. | the distribution of serotonin-containing cells (sc cells) in the human alimentary tract was studied by means of the fluorescent histochemical method of falck et al. on surgically resected specimens. no sc cells could be observed in the nonmucosal parts of the alimentary tract and in the squamous cell epithelium of the esophagus. the richest sc cells were observed in the upper portion of the small intestine (namely the duodenum and the jejunum). the rectum was relatively rich in the distribution ... | 1975 | 1234108 |
| atp-ppi exchange activity of progesterone receptor. | progesterone receptor preparations from avian oviduct catalyze a pyrophosphate (ppi)-exchange reaction between atp and 32p-labeled ppi. the reaction requires atp exclusively and is mn++-dependent. this enzyme activity is detectable in receptor preparations that have been purified extensively by chromatography on atp-sepharose and deae-sephadex columns. polyacrylamide gel electrophoresis of purified preparations reveals a comigration of [3h]progesterone-receptor complex and the enzyme activity. t ... | 1976 | 185612 |

| comparative in vitro activity of cefbuperazone against anaerobic bacteria isolated from community hospitals. | the activity of cefbuperazone against 266 strains of anaerobic bacteria was determined by the agar dilution method and compared with cefoxitin, moxalactam, piperacillin, and clindamycin. all strains were recent clinical isolates from community hospitals. all agents tested showed good activity against bacteroides fragilis, fusobacterium spp., propionibacterium spp., clostridium septicum, clostridium perfringens, and the anaerobic, gram-positive cocci and gram-negative cocci. cefbuperazone, cefoxi ... | 1985 | 3985600 |
| in vitro activity of sch 34343 and cefbuperazone against anaerobic bacteria. | the in vitro activities of sch 34343, a new penem antibiotic, and cefbuperazone, a new cephamycin antibiotic, were determined against 459 clinical anaerobic bacterial isolates and compared with the activities of imipenem and cefoxitin, respectively, by an agar dilution method. both penems showed potent and similar activity against all anaerobic bacteria tested, particularly peptococcus spp., bacteroides fragilis, and clostridium perfringens. all organisms except a single strain of fusobacterium ... | 1985 | 4015069 |
| enzymatic removal of bilirubin from blood: a potential treatment for neonatal jaundice. | current treatments for severe jaundice can result in major complications. neonatal jaundice is caused by excessive accumulation of bilirubin in the blood. a small blood filter containing immobilized bilirubin oxidase was developed to reduce serum bilirubin concentrations. when human or rat blood was passed through the enzyme filter, more than 90 percent of the bilirubin was degraded in a single pass. this procedure may have important applications in the clinical treatment of neonatal jaundice. | 1985 | 4048947 |
| the effect of prenatal procarbazine treatment on brain development in the rat. | groups of pregnant sprague-dawley rats were treated orally with procarbazine, an antineoplastic drug, at dose levels of 0, 1.0, 2.5, 5.0, 7.5, and 10.0 mg/kg/day from days 12 through 15 of gestation. following normal delivery, offspring were raised until day 21 and sacrificed, and their brains removed and weighed. a dose-dependent micrencephaly, characterized by hypoplasia of the cerebral hemispheres, was seen starting at 2.5 mg/kg/day. in a second study, groups of pregnant female rats were give ... | 1985 | 4049278 |
| plasma protein binding of dipyrone metabolites in man. | four metabolites of dipyrone, 4-methylaminoantipyrine (maa), 4-aminoantipyrine (aa), 4-formylaminoantipyrine (faa) and 4-acetylaminoantipyrine (aaa) can be identified in human plasma after its oral administration. the plasma protein binding of the metabolites in samples from 20 healthy volunteers was determined by ultrafiltration. none of the metabolites were found to be extensively bound to plasma proteins. the binding of maa and aa was relatively higher than of faa and aaa, as expected from th ... | 1985 | 4054207 |
| synthesis and content of a dna-binding protein with lactic dehydrogenase activity are reduced by nerve growth factor in the neoplastic cell line pc12. | we have previously demonstrated that synthesis of a 34 kd protein having specific, high affinity for single-stranded dna (34kd-ssb protein), is markedly inhibited by nerve growth factor (ngf) in the neoplastic clonal cell line pc12. we report here that total content as well as mrna for this protein are progressively reduced in pc12 cells undergoing mitotic arrest and morphological differentiation induced by ngf. it is also shown that binding of the 34k-ssb protein to ssdna is fully inhibited by ... | 1985 | 4054226 |
| automated methods for determination of fat and moisture in meat and poultry products: collaborative study. | a collaborative study was conducted to compare automated methods for rapid determination of fat and moisture in meat and poultry products with the official aoac solvent extraction and forced-air oven methods, respectively. fourteen products were tested, with fat and moisture contents ranging from 2 to 43% and 44 to 74%, respectively. eight of the collaborating laboratories analyzed the products by using a moisture/fat analyzer; 4 laboratories used the aoac methods. standard deviations for within ... | 1985 | 4055632 |
