124 sera of children with chronic bronchitis, chronic pneumonia, bronchial asthma, exogenic allergic alveolitis, congenital developmental defects of the lungs and the syndrome of the situs inversus of organs were examined with a view to study the state of humoral immunity to tissues. The study was carried out by means of the enzyme-linked immunosorbent assay with the use of collagen, elastin, DNA (native and denaturated), membrane antigens of the lung, the liver, the small intestine and the large intestine. Among all groups of patients autoimmune disturbances, manifested by a rise in the level of autoantibodies of different specificity, were registered. The degree of manifestation of autoimmune disturbances depended on the kind of pathology. After treatment a decrease in the level of autoantibodies was registered in the examinees. 相似文献

The effects of ethanol injections on the F2 offspring of the cross between large-brain (LB) and small-brain (SB) mouse strains selected for high and low relative brain weights, respectively, have been studied. The parental strains have significantly differed in brain weight for many generations. The effects of ethanol (2.4 g/kg) have been compared in four subpopulations of mice that differ pairwise in brain weight. One pair of subpopulations has been isolated from the hybrid group and the other, from generation 22 of selection of the parental strains. The results of ANOVA have demonstrated that brain weight is related to the response to ethanol injections. The parameters of stereotyped behavior, which increased in after ethanol injections and reflected the decrease in exploratory activity) were different in mice with high and low relative brain weights. The pattern of behavioral changes after ethanol injections is the second (after increased learning ability) behavioral trait found to be correlated with brain weight. 相似文献

This study examines the influence of the detergents “Obychnyi poroshok” and “Ariel” (at 0.1, 1, and 10 mg/l) on the growth and physiological state of the benthic marine microalga Attheya ussurensis. Cell number, growth rate, and oxygen productivity turned out to be the most sensitive characteristics for evaluation of toxic effects, while the pH of the culture medium and the contents of chlorophyll a and carotenoids were more tolerant to detergent. Toxicants in concentrations of 0.1 and 1 mg/l had a weak inhibitory effect on the microalga A. ussurensis; at 10 mg/l, the detergent Ariel exerted a greater inhibitory effect on the microalga than Obychnyi poroshok did. 相似文献

The study of cross-reactions between healthy pulmonary tissue antigens and Moraxella catarrhalis with the use of SDS-electrophoresis and immunoblotting revealed that in the component of healthy pulmonary tissue with a mol. wt. of 40 kD epitopes existed to which antibodies were produced, capable of cross reaction with the components of M. catarrhalis with a mol. wt. of 35 kD and 70 kD. In addition, the presence of cross-reactions between cytokeratin-8, protein contained in healthy pulmonary tissue, and M. catarrhalis antigens was established. 相似文献

In cervical secretions of healthy non-pregnant women of the reproductive age high concentrations of ant-inflammatory cytokines, greatly exceeding those in blood serum, were detected. During pregnancy the level of TNF-alpha in cervical secretions dropped. The inflammation of the uterus neck was accompanied by a drop in the levels of IL-alpha and IL-1beta and a rise in the level of IL-8 in cervical secretions in pregnant and non-pregnant women. Similar changes in the cytokine profile occurred also in the blood serum, but they were less pronounced and could be observed only in non-pregnant women. The threat of the interruption of pregnancy, developing simultaneously with cervicitis, was accompanied not only by changes in the levels of cytokines in cervical secretions, but also by a perceptible increase in the content of IL-1alpha in the blood serum. 相似文献

Pharmacological analysis was used for studying the influence of 24-hour deprivation of paradoxical sleep by Jouvet method on retention of conditioned reaction of passive avoidance in rats. Psychotropic substances of different action were used for the analysis: nootropes as anti-amnestic--pyracetam (400 mg/kg), kleregil (100 mg/kg), centrofenoxin (50 mg/kg) and watersoluble salt of 3-oxypiridin derivative (3-OP) (50 mg/kg) and tranquilizer of bensodiazepine series phenazepam (1 mg/kg) as antistress and antiphobic. It was established that 24-hour deprivation disturbed the elaborated reaction but did not change the rate of emotionality and orienting-investigating behaviour of rats in the open field. Nootropes effectively restored the conditioned passive avoidance reaction while phenazepam had no effect. This allows to suggest that Jouvet method of paradoxical sleep deprivation elicits amnesia and its cause is not only stress but deficit of paradoxical sleep. 相似文献

Degradation ofortho-chlorophenol,para-chlorophenol, and 2,4-dichlorophenoxyacetic acid by the bacterial community of anaerobic sludge 总被引:1,自引:0,他引:1

The bacterial community of anaerobic sludge could degradeo-chlorophenol,p-chlorophenol, and 2,4-dichlorophenoxyacetic acid at concentrations as high as 100 mg/l. The time needed for the degradation
of a given chlorinated phenol derivative increased 1.5- to 2-fold upon a twofold increase in its concentration (from 50 to
100 mg/l). The duration of the adaptation period depended on the compound studied and on its concentration. The degradation
of 2,4-dichlorophenoxyacetic acid proceeded via 2,4-dichlorophenol andp-chlorophenol as intermediates; the degradation ofo-chlorophenol occurred with the formation of phenol. The dynamics ofp-chlorophenol degradation and chloride ion accumulation were studied. 相似文献

The results of a study of the temperature dependence of laser-induced fluorescence for four marine microalgae cultures that belonging to different taxonomic groups are described. The fluorescent properties of microalgae that were exposed to temperature stress up to irreversible changes in their cells have been examined. A comparative analysis has been performed and the models for the dependence of laser-induced fluorescence intensity on the temperature for the microalgal cell pigments have been constructed. The microalgae differ in both their dependence of fluorescence intensity on the thermal stress factor and the stress temperature value, which suggests that these characteristics are species specific. 相似文献
