| time in chemo-immunotherapy models: an absolute or a relative variable? lessons from the levamisole experience. | an analysis is presented of the findings from the available studies in several cancer models, where 2.5-20 mg/kg levamisole was given in combination with different types of cytostatic drugs. it appears that in chemo-immunotherapy experiments it may be preferable to measure time variables (increase in life span, timing of chemotherapy and of immunotherapy) as a per cent of the median survival time of the untreated controls instead of using time as an absolute measure (in days). as regards the stu ... | 1980 | 551097 |
| time--a neglected aspect of psychiatric treatments. | this review attempts to deal with the complex issues involved in the time to heal, with special reference to psychological processes. the questions of convalescence and relapse in organic medicine are explored and extrapolated to psychiatric processes. the concept of a latency period of change in treatment outcome is discussed with reference to both less complicated reactive states as well as highly charged neurotic processes. the problems of recognizing slow but perceptible change and separatin ... | 1980 | 283799 |
| children in cars. results of an observational study in new zealand. | if children under the age of 14 years were adequately restrained while travelling in cars, many deaths and injuries could be prevented. seventeen thousand, one hundred and fifty-five children under 14 years of age were observed in cars. only 20 percent overall were appropriately restrained. a breakdown into different age groups showed that the percentage of children who were adequately restrained varied with ages: less than six months 54 percent; six months-four years 18 percent; five-seven year ... | 1980 | 294525 |

| stimulation of prostaglandin e production by bacterial endotoxins in cultured human synovial fibroblasts. | e coli, shigella, salmonella, and cholera endotoxins stimulated prostaglandin e (pge) production by cultured human synovial and foreskin fibroblasts. the minimal effective dose of shigella endotoxin was 2 micrograms/ml and a maximal response was observed at 10 micrograms/ml. pge stimulation was first detected 7 hours after addition of cholera endotoxin. stimulation by shigella endotoxin of both pge and hyaluronic acid production was inhibited by indomethacin and aspirin. the present results sugg ... | 1980 | 6157394 |
| [change in the nonesterified fatty acid makeup of shigella flexneri no. 15172 type 3a in the process of passage on developing chick embryos]. | composition of nonesterified fatty acids/nefaj from shigella flexneri was similar to that from other gram-negative bacteria of the enteritic group. at the same time, nefa of the dysenteric bacteria contained comparatively high amount of branched and cyclopropane-bearing fatty acids. adaptation of shigella flexneri in the medium of developing chicken embryo led to a distinct increase in total nefa content as well as of cyclopropane-bearing and saturated fatty acids in the bacteria and to a decrea ... | 1980 | 6245536 |
| genetic and physical evidence for plasmid control of shigella sonnei form i cell surface antigen. | virulent shigella sonnei synthesize a surface antigen (form i) which appears to be one of several requirements needed for this host to invade epithelial cells. upon restreaking on agar media, form i cells readily and irreversibly generate form ii cells that lack the form i antigen. all form ii cells are avirulent. plasmid deoxyribonucleic acid of form i and ii cells of four different s. sonnei isolates, obtained from different areas of the world, was analyzed by agarose gel electrophoresis. a la ... | 1980 | 6249756 |
| isolation of two protein-free and chemically different lipopolysaccharides from bordetella pertussis phenol-extracted endotoxin. | endotoxin prepared from several bordetella pertussis strains in both immunological phases i and iv gave two lipopolysaccharide peaks (lps-i and lps-ii) when analyzed on hydroxylapatite columns in a phosphate buffer containing 0.1% sodium dodecyl sulfate; these lipopolysaccharides, present in the ratio of 2:3, are true endotoxins by both chemical and biological criteria. endotoxins isolated from escherichia coli, salmonella typhimurium, and shigella flexneri gave single lipopolysaccharide peaks w ... | 1980 | 6249793 |

| [isolation and characteristics of polymyxin-resistant mutants of shigella flexneri]. | some characteristics of s. flexneri 2a mutants resistant to various concentrations of polymyxin m were studied. the data indicate that mutations resulting in low (50 microgram/ml) and high (300 microgram/ml) levels of the antibiotic resistance were determined by different genes. polymyxin resistance led to changed permeability of the outer membrane with respect to detergents and some antibiotics, such as aminoglycosides, penicillins, chloramphenicol and amphotericin b but did not change sensitiv ... | 1980 | 6252826 |
| synthesis and utilization of siderophores by shigella flexneri. | strains of shigella flexneri secrete a hydroxamate-type siderophore when grown in low-iron media. this hydroxamate appears to be identical with aerobactin, a siderophore synthesized by aerobacter aerogenes. in contrast to other enteric bacteria, s. flexneri did not produce detectable phenolate siderophores, although it could utilize an exogenously supplied phenolate. | 1980 | 6447691 |
| [tendencies in the epidemic process of dysentery in ryazan]. | in shigellosis caused by sh. sonnei and sh. flexneri the epidemic process was found to have considerable difference in the tendencies and pace of its development. shigellosis which dominated in the etiological structure at the period following 1966 was dysentery caused by sh. sonnei; it showed the tendency towards a decrease in morbidity rate. dysentery caused by sh. flexneri was second in respect to the frequency of its occurrence after 1966 and showed the tendency towards increase. the simulta ... | 1980 | 6449121 |
