| use of lincomycin, methicillin and ristomycin in the nutrient media for isolating pathogenic intestinal microorganisms. | elective-differentiating solid nutrient media for simultaneous isolation of vibrioes, salmonella and shigella were developed. antibiotics active against grampostive microflora and dry bile salts inhibiting the growth of proteus were used as the inhibitors of the growth of the accompanying microflora. the medium was lincomycin and the bile salts may be prepared in a dry form. | 1975 | 2096 |
| lactulose therapy in shigella carrier state and acute dysentery. | antibiotic-resistant shigella are increasingly prevalent. lactulose, a non-absorbable disaccharide, was investigated as an alternative therapy for shigella infection on the hypothesis that the short-chain fatty acids (inhibitory to shigella) resulting from metabolism of lactulose by normal colonic flora would diminish shigella excretion. a long-term antibiotic-refractory carrier (large bowel) excreting 10(4) to 10(7)shigella sonnei/g of feces was given two courses of lactulose (of 24 and 16 days ... | 1975 | 2098 |
| significance of starter cultures for raw sausage aging in view of food and nutrition hygiene. | the authors studied the effects of liquid starter cultures on the survival of pathogenic germs. it was found that the foreign bacteria tested differed in growth limitation which is obviously dependent on acidity and the amount of lactic acid produced by fermentation. since the pathogenic bacteria differ in the ability to survive, it is imperative to observe strict hygienic measures in preparing starter cultures and to use absolutely sterile monocultures for raw sausage ageing. | 1976 | 8718 |

| enterobacterial common antigen: isolation from shigella sonnei, purification and immunochemical characterization. | in the studies presented the effective procedure of isolation and purification of enterobacterial common antigen from shigella sonnei has been elaborated. the method is based on sonification of bacterial suspension in the presence of lysozyme and edta and subsequent extraction of the pellet with boiling water. the crude extract of common antigen was purified by fractionation with ethanol and chromatography on silica gel and sephadex lh-20. the comparison of several extraction procedures of enter ... | 1978 | 102511 |
| effect of cobalt-60 radiation on response to endodontic therapy in monkeys. | response of teeth that had received therapeutic doses of cobalt-60 radiation to endodontic therapy were investigated in three monkeys. the results indicated no appreciable effect of the irradiation on the response to root canal treatment aside from reduction in osteoblastic activity. | 1978 | 103612 |

| determination of meningococcal antibodies by microassay. | a modified microassay procedure, using triphenyltetrazolium chloride as a germination indicator, was compared with a macroassay method proposed by the world health organization for determining the level of antibodies before and after immunization with group a meningococcal polysaccharide vaccine. there was excellent agreement between the results obtained by the two methods. the vaccine used appeared to be safe and immunogenic. | 1978 | 104795 |
| effect of auranofin, a new antiarthritic agent, on immune complex-induced release of lysosomal enzymes from human leukocytes. | auranofin, an oral chrysotherapeutic agent effective in the treatment of rheumatoid arthritis (ra), was found to be a potent, noncytotoxic inhibitor of igg-rf immune complex-induced lysosomal enzyme release (ler) from human leukocytes. at a concentration of 1 microg au/ml (5 microm), auranofin produced a marked reduction in beta-glucuronidase (100%), acid phosphatase (88%), and lysozyme (72%) release. in contrast, gold sodium thiosulfate (gst, an injectable gold compound) had no inhibitory activ ... | 1977 | 104928 |
| transcription and translation in a pleiotropic streptomycin-resistant mutant of escherichia coli. | the role of the ribosomal protein s12 (streptomycin protein) in ribosome function and in other metabolic processes in the cell has been investigated. a spontaneous streptomycin-resistant strain of escherichia coli (sm3) carrying a mutation in the rpsl gene is deficient in its ability to induce the synthesis of the enzyme bets-galactosidase. it was demonstrated that the reduced rate of enzyme synthesis results from deficiencies in both the transcription of the lactose operon and translation of th ... | 1979 | 104958 |
| implications for adult roles from differential styles of mother-infant bonding: an ethological study. | ethological observations of maternal and infant behaviors of nine vervet monkey pairs (cercopithecus aethiops sabaeus) showed the effects of differential styles of early maternal responsiveness on later infant competence. those infants receiving the least amount of maternal responsiveness and the most time-off the mother in the first 3 months of development were more socially competent at 6 months of age. the results are discussed within current ethological "attachment" theories. the detachment ... | 1979 | 105083 |
