| practolol inhibits human skin fibroblast cell mat hydroxyproline accumulation. | despite being poorly absorbed practolol (n-4-2-hydroxy-3-(1-methyl-ethyl)-amino propoxy phenyl acetamine) inhibited the accumulation of cell mat hydroxyproline, a measure of collagen synthesis, by human skin fibroblasts (dt2ph) in vitro, (id50 0.8 x 10(-3) m). the degree of inhibition was dependent on the concentration of practolol used and the incubation time. neither preinitiation of collagen synthesis nor omitting ascorbic acid from the incubation medium modified this inhibitory action. in co ... | 1987 | 3687592 |
| proline requirement for glucose utilization by peptostreptococcus anaerobius atcc 27337. | resting cells of peptostreptococcus anaerobius maintained under anaerobic conditions were unable to metabolize either glucose or alanine. the addition of proline to the appropriate suspension, however, resulted in the immediate utilization of both compounds. fermentation of alanine by the cells required that stoichiometric concentrations of proline be present in the medium; and during the oxidation of alanine, proline was simultaneously reduced to the ring cleavage product delta-aminovaleric aci ... | 1987 | 3804441 |
| controlled evaluation of modified radiometric blood culture medium supplemented with gelatin for detection of bacteremia and fungemia. | although the addition of 1.2% gelatin to broth blood culture media containing sodium polyanetholesulfonate has been shown to enhance detection of certain bacteria, including neisseria meningitidis, n. gonorrhoeae, peptostreptococcus anaerobius, and gardnerella vaginalis, the effect of such supplementation on the detection of other microorganisms causing bacteremia and fungemia is not known. therefore, we studied bactec 6b medium with and without gelatin in 6,833 paired comparisons to examine the ... | 1987 | 3624437 |
| identification of anaerobic bacteria using high-performance liquid chromatography. | 20 species of the genera clostridium, bacteroides, fusobacterium and the type strains of peptostreptococcus anaerobius, peptococcus asaccharolyticus, veillonella parvula and propionibacterium acnes were examined for the production of volatile (vfa) and nonvolatile (nvfa) short-chain fatty acids using high-performance liquid chromatography (hplc) with a column for organic acids (aminex hpx-87h). 10 min are needed for sample preparation and the vfa and nvfa were detected simultaneously in a single ... | 1987 | 3673341 |
| beta b1 crystallin is an amine-donor substrate for tissue transglutaminase. | the effects of tissue transglutaminase on the water-soluble proteins in bovine lens homogenates are described. addition of liver transglutaminase and ca2+ to calf lens homogenates resulted not only in the appearance of 50- and 57-kda dimers, but also in a decrease in the amount of beta b1 crystallin and the almost complete disappearance of beta b3 and beta a3. this is not the result of ca2+-induced proteolysis, since histamine completely inhibits this phenomenon. it may be concluded that these p ... | 1987 | 2887447 |
| surgical cannulation of a hepatic vein in dairy cows utilizing diagnostic ultrasound. | use of a diagnostic ultrasonography unit in the placement of hepatic vein catheters is described. diagnostic ultrasound proved to be a safe and rapid means of identifying the hepatic venous circulation. it provided a clear visual guide in an otherwise blind surgical procedure and allowed for a precise determination of catheter placement. thus, the method could be used to advantage in other types of catheterizations. use of ultrasonography reduced the duration of surgery by 50 to 75%, thereby min ... | 1987 | 3294948 |
