processing-independent in vitro translocation of cytochrome p-450(scc) precursor across mitochondrial membranes.in the presence of a membrane-permeable metal chelator, bovine adrenal cortex mitochondria imported p-450(scc) precursor without processing of the amino-terminal extension peptide. the imported precursor was bound to the matrix side surface of the inner membrane. when the inhibition due to the metal chelator was removed, the imported precursor was processed to the mature form. unprocessed precursor was also detected in mitochondria when the import reaction was carried out at relatively low tempe ...19863818579
similarity principles and intrinsic geometries: contrasting approaches to interspecies scaling.we criticize standard allometric approaches on the grounds that they emphasize scaling to one variable at a time, whereas chemically reactive hydrodynamic systems involved in pharmacokinetic phenomena are of higher dimension. we show that attempts based on mechanical similitude to set a dosage that would be equivalent across species (for example, from mouse to humans) lead to ambiguous results. another failing of standard allometry may be its incapability to accommodate the neoteny of homo sapie ...19863820095

the iridovirus frog virus 3: a model for trans-acting proteins.the amphibian iridovirus, frog virus 3 (fv3), produces at least two trans-activating proteins that stimulate the expression of viral genes. one of these proteins induces transcription from the promoter of an immediate-early fv3 gene, whereas the other induces transcription from exogenously methylated dna. these proteins may serve as a model for both viral and cellular trans-acting factors.19863153144
purification of the thermostable direct hemolysin of vibrio parahaemolyticus by immunoaffinity column chromatography.a simple method involving immunoaffinity column chromatography to purify the thermostable direct hemolysin of vibrio parahaemolyticus was developed. the thermostable direct hemolysin purified from the culture supernatant of a strain isolated from the first reported case of v. parahaemolyticus infection in china in 1985 was indistinguishable from the hemolysins purified from strains isolated in japan.19863697844
evidence for the presence of a novel biosynthetic pathway for norspermidine in vibrio.enzymatic studies of the cell extracts of vibrio alginolyticus and v. parahaemolyticus provided evidence that there exists a novel biosynthetic pathway for norspermidine (nh2(ch2)3nh(ch2)3nh2), a major polyamine species. in this pathway, the schiff base formed between aspartic beta-semialdehyde and 1,3-diaminopropane is first reduced by a nadph-dependent enzyme to yield "carboxynorspermidine" (nh2(ch2)3nh(ch2)2ch(nh2)cooh), which is in turn decarboxylated by a pyridoxal phosphate dependent enzym ...19863697846
[cytogenetic activity of metabolites of pesticides representing different classes of chemical compounds].the cytogenetic activity of some substances formed in agricultural plants during metabolism of pesticides of four classes of chemical compounds was studied in the culture of human peripheric blood lymphocytes. metabolites were shown either to have mutagenic properties similar to those of the initial compounds (ziramtetramethylthiourea, both being mutagens; captan-phthalimide, both possessing no cytogenetic activity) or to be considerably transformed in comparison with them as a result of deactiv ...19863705167

role of glucagon in splanchnic hyperemia of chronic portal hypertension.the role of glucagon as a blood-borne mediator of the hyperdynamic circulation associated with chronic portal venous hypertension was assessed in the rat portal vein stenosis model. selective removal of pancreatic glucagon from the circulation was achieved by intravenous infusion of a highly specific glucagon antiserum. blood flow to splanchnic organs, kidneys, and testicles was measured with radioactive microspheres, and the reference-sample method. glucagon antiserum had no effect on blood flo ...19863777172
participation of iron on the growth inhibition of pathogenic strains of mycobacterium avium and m. paratuberculosis in serum.serum, which is low in freely-available iron, was bacteriostatic for m. avium and m. paratuberculosis irrespective of the ability of these organisms to produce the iron-chelators mycobactin and exochelin for iron acquisition. bacteriostasis was overcome when the serum was supplemented with exochelin or mycobactin, but only if the mycobacteria had previously adapted to growth in a low iron environment. the results imply that for studies on mycobacterial pathogenicity the test cultures should be g ...19863788345
occurrence and distribution of halophilic vibrios in subtropical coastal waters of hong kong.the summer occurrence and distribution of halophilic vibrios in the subtropical coastal waters of hong kong were investigated. the density of vibrios in six sample sites ranged from 90 to 6,700 per ml, which made up 0.41 to 40% of the total bacterial populations of these sample sites. the sucrose-positive vibrios were found to be much more common (88% of total vibrios) than the sucrose-negative ones. a total of 48 strains belonging to six vibrio species were fully characterized. among these, vib ...19863789725
low-density lipoprotein apheresis and regression of atherosclerotic plaque in vitro.short-term organ culture and primary cell culture of human aorta were used to study the effect of selective removal of low-density lipoproteins (ldls) from the surrounding medium (ldl apheresis) on the lipid content of cultured tissue and cells, respectively. ldl apheresis was performed by passing the culture medium through immunosorbent containing agarose-bound goat antibodies against human ldl. ldl apheresis promoted the decrease of lipids of all classes in the cultured atherosclerotic plaque. ...19863800702
furosemide lowers intracranial pressure by inhibiting csf production.furosemide administration effectively lowers intracranial pressure in newborn preterm and term rabbit pups. this effect may be due to the diuretic action of the drug, its ability to inhibit cerebrospinal fluid production or to a combination of both. to test these possibilities newborn rabbits were either injected with furosemide and left unmolested for 6 hours, or anaesthetized and subjected to ventriculocisternal perfusions. during the 6 hour postnatal period the decrease in body weight was 8 t ...19863811613

consequences of treatment of gastrointestinal infections.diarrhoeal disease is a common problem in developing countries. as a result of recent advances in diagnostic methodology, the causative agents can now be identified in most cases of acute diarrhoeal diseases. enteric bacterial pathogens are the common cause of gastroenteritis in developing countries. appropriate uses of antibiotics in selected cases of diarrhoea will decrease symptoms or reduce faecal shedding of the organism and prevent spread of infection. antimicrobial agents improve the diar ...19863547620
isotope exchange at equilibrium studies with rat muscle adenylosuccinate synthetase.the kinetic mechanism of rat muscle adenylosuccinate synthetase was studied by determining the rates of isotope exchange at equilibrium. a random sequential binding mechanism was indicated for both the forward and reverse reactions. aspartate, adenylosuccinate, gdp, and pi were determined to bind in rapid equilibrium. gtp exchanges with both gdp and pi at the same rate, which is similar to the exchange rate of imp with adenylosuccinate. aspartate exchanges with adenylosuccinate at a higher rate ...19863542024
experience with isoxicam and catabolin.1 synovial cells produce a protein factor, catabolin, that induces chondrocytes to resorb their own matrix with the release of glycosaminoglycan (gag). 2 studies were performed to determine the effect of isoxicam, a new nsaid, on gag production in a catabolin system utilizing tissue culture of bovine nasal septum in a medium containing pooled synovial tissue from young pigs. 3 using fresh medium containing no synovial tissue, the release of gag by inherent cartilage breakdown was 49.7% after 8 d ...19863497659
