| an estimation of dental treatment needs in two groups of refugees in sweden. | the aim of this study was to estimate dental treatment need in groups of chilean and polish refugees in sweden. of the nordic countries, sweden accepts the greatest number of refugees. an average of 5000 refugees arrived annually in 1981-85, increasing to 15,000 during 1986-87. refugees and their families now comprise 93% of non-nordic immigration. in 1981-83 a sample of 193 chilean and 92 polish refugees in the county of stockholm was selected for this study. dental treatment needs were calcula ... | 2000 | 2195841 |
| serum and tissue cage fluid concentrations of ciprofloxacin after oral administration of the drug to healthy dogs. | ciprofloxacin, a fluoroquinolone antimicrobial agent, was administered orally to 4 healthy dogs at dosage of approximately 11 and 23 mg/kg of body weight, every 12 hours for 4 days, with a 4-week interval between dosing regimens. serum and tissue cage fluid (tcf) concentrations of ciprofloxacin were measured after the first and seventh dose of each dosing regimen. the peak concentration was greatest in the serum after multiple doses of 23 mg/kg (mean +/- sem; 5.68 +/- 0.54 micrograms/ml) and lea ... | 1990 | 2195927 |
| increased activity of digoxin-like substance in low-renin hypertension in acromegaly. | arterial hypertension is common in acromegaly, but the pathogenesis of this complication remains unknown. to determine the role of an endogenous na,k pump inhibitor/digoxin-like substance (dls) in the pathogenesis of hypertension in acromegaly 76 subjects: 28 with acromegaly, 20 with essential hypertension and 28 healthy controls were studied. serum dls was measured with the use of radioimmunoassay and bioassay by the inhibition of digoxin-sensitive erythrocyte 86-rb uptake. in acromegaly, the a ... | 1997 | 2196126 |
| rational treatment of acid-base disorders. | acid-base derangements are encountered frequently in clinical practice and many have life-threatening implications. treatment is dependent on correctly identifying the acid-base disorder and, whenever possible, repairing the underlying causal process. bicarbonate is the agent of choice for the treatment of acute metabolic acidosis. controversy surrounds the use of alkali therapy in lactic acidosis and diabetic ketoacidosis, but bicarbonate should clearly be administered for severe acidosis. in m ... | 1997 | 2196165 |
| inactivation of legionella pneumophila by monochloramine. | chloramination which is used in south australia to control the growth of naegleria fowleri, was investigated to see if it would also control that of legionella pneumophila. it was found that l. pneumophila was more sensitive than escherichia coli to monochloramine. at 1.0 mg/l, a 99% kill of l. pneumophila was achieved in 15 min compared with 37 min for a 99% kill of e. coli. combined with the stability of monochloramine, even at elevated temperatures, the results suggest that this disinfectant ... | 1990 | 2196255 |
| aluminum, a neurotoxin which affects diverse metabolic reactions. | experimental evidence is summarized to support the hypothesis that chronic exposure to low levels of aluminum may lead to neurological disorders. these disorders result from defective phosphorylation--dephosphorylation reactions, reduced glucose utilization and site-specific damage inflicted by free radicals produced by altered iron metabolism. the brain is a highly compartmentalized organ. therefore, a co-localization of critical mass of metabolic errors rather than a single event may be essent ... | 1990 | 2198876 |

| thermodynamic properties of globular proteins and the principle of stabilization of their native structure. | a semi-empirical method has been used to estimate the thermodynamic parameters of hydration of buried surface areas of ribonuclease s, lysozyme and myoglobin from the model of complete unfolding according to ooi et al. ((1987) proc. natl. acad. sci. usa 84, 3086-3090). the buried surface area of proteins is considered as the difference between the accessible surface area of native protein and the completely extended polypeptide chain according to lee and richards ((1971) j. mol. biol. 55, 379-40 ... | 2008 | 2223840 |
| [detection of protease specifically splitting actin in revertants of shigella flexneri l-forms]. | proteolytic activity of cell extracts from revertants of shigella flexneri l-forms as well as biochemical properties of these strains and their sensitivity to antibiotics were studied. the protease found earlier in cells of strain e. coli a2 was shown to be synthesized by one of 8 revertants under study. this protease split actin and did not split some other proteins, its activity was inhibited by inhibitors of metalloproteases. strain 5a2c which produced the protease was similar to the strain e ... | 1990 | 2224099 |
| a randomized comparison of manipulation of the fractured nose under local and general anaesthesia. | reduction of simple nasal fractures may be performed under local or general anaesthesia: the latter is by far the most popular method in britain, though why is hard to define. we have attempted to compare the 2 approaches by means of a randomized, prospective trial. fifty consecutive, adult patients with radiologically proved fractures of the nasal bones were randomized to a local or general anaesthesia group and underwent manipulation with asch's and walsham's forceps between 7 and 15 days post ... | 2008 | 2225504 |
| [cloning of shigella flexneri 2a genes coding for restriction- modification system sfl2ai]. | the sfl2ai system of restriction-modification (rm) was revealed in the cells of shigella flexneri encoded by pkmr114 plasmid belonging to the incn incompatibility group. the genes for sfl2ai rm system were cloned. the system was ascribed to the enzymes of the ecorii specificity, as shown by in vivo and in vitro experiments. restriction analysis of these genes' region and antigenic properties of the sfl2ai endonuclease pointed to significant differences between this and ecorii rm systems. | 1990 | 2227395 |
