Objective To evaluate the value of early secreted antigen terget 6000(ESAT-6)-induced interferon-gamma(IFN-γ)response in vitro in diagnosis of tuberculosis and mycobacterium tuberculosis infections.Methods ESAT-6 was added into peripheral whole blood to induce IFN-γ,and concentration of IFN-γ was detected by ELISA.Comparing with saline control,the percentage of increase was regarded as the value of ESAT-6 induced IFN-γ response.ESAT-6-induced IFN-γ response was analysed in the following four aspects:to compare with the people intimate contact to tuberculosis(60 cases),the sputum culture confirmed active tuberculosis patients(46 eases)and healthy people(55 cases);to compare with children(68 cases),adolescents(52 cases)and elder people(45 cases)by follow up;dynamically observe 20 tuberculosis patients during long-time treatment;to compare HIV(+)and TB(+)people(78 cases)with HIV(+)and TB(-)people(60 cases).Results Between people intimate contacts to tuberculosis and active tuberculosis patients,ESAT-6 response has high sensitivity;ESAT-6 response in children and adolescents was completely consistent with the following clinical diagnosis and prognosis;ESAT-6 response decreased during treatment duration in 65%tuberculosis patients;in HIV(+)and TB(+)cases,the sensitivity of tuberculosis diagnosis by ESAT-6 response was 87.2%.Conclusion In vitro IFN-γ response induced by ESAT-6 is helpful in diagnosis of tuberculosis,especially for children and adolescents.And it is also available for differential diagnosis of HIV(+)patients with tuberculosis.  相似文献

Objective To investigate the immune protection of heparin-hinding hemagglutinin ad-hesin(HBHA) and to estimate its potential diagnostic value. Methods Native HBHA were used to stimu-late peripheral blood mononuelear cells (PBMCs) from different infected-cases including PPD negative healthy control, PPD positive latent tuberculosis(LTB) infection, pulmonary tuberculosis, and the IFN-γ/in the supernatant of culture was detected. Meanwhile, HBHA specific IgG antibody in the sera was detected by ELISA. Results The middle level of HBHA specific IFN-γ of the three groups were 49.5 pg/ml, 781.9 pg/ml and 341.8 pg/ml, respectively. IFN-γ of latent tuberculosis group was much higher than that of the control, and slightly higher than that of the patients with pulmonary tuberculosis. And the absorbency of the IgG antibody to HBHA in the three groups was 0.212±0.066, 0.224 ± 0.076 and 0.285±0.078. lgG an-tibody in the patients with pulmonary tuberculosis is higher than that of the healthy, including the control and the latent tuberculosis infection. Conclusion HBHA has good immunogenieity, and it can stimulate the LTB to release high level IFN-γ, suggests that the LTB doesn't develop active tuberculosis may rely on its protection. HBHA specific. IFN-γ release may identify 1,333 from the healthy. Anti-HBHA antibody plays an auxiliary role in the diagnosis of pulmonary tuberculosis.  相似文献

Although it has been known that y8 T cells may play an important role in the immune response to infection of Mycobacterium tuberculosis (M. tb), the mechanisms by which the T8 T cells participate in the innate and/or acquired immunity to tuberculosis (TB) have not been full elucidated. In the present study, 27 patients with active pulmonary TB and 16 healthy donors (HD) were performed. We found that proportion of IL-17-producing cells among lymphocyte was similar between TB patients and HD, whereas the proportions of γδ T cells in IL-17- producing cells (59.2%) and IL-17-producing cells in γδ T cells (19.4%) in peripheral blood were markedly increased in TB patients when compared to those in HD (43.9% and 7.7%, respectively). In addition, the proportions of IFN-γ-producing γδ T cells in TB patients were obviously lower than that in HD. Upon re-stimulated with M. tb heat-treated antigen (M. tb-HAg) in vitro, fewer IL-17-producing γδ T cells were generated from HD and TB patients, whereas IFN-γ-producing γδ T cells were increased in TB patients compared to that in HD. Our findings in TB patients and healthy human were consistent with other murine investigation that the IL-17- producing γδ T cells were main source of IL-17 in mouse model of BCG infection, suggesting that γδ T cells might be involved in the formation of tubercular granuloma in pulmonary TB patients, but need further identification.

A further analysis of already published data supports the position that retardates of low ability level less frequently have retarded siblings, retarded parents, and parents low in occupational level than do retardates higher in ability level. The analysis supports the position that there are two types of retarded individuals, persons retarded as a result of gene or chromosomal anomalies, brain injury, etc., who more frequently occur in the lower-level retardate group, and persons whose retardation represents polygenic segregation, who more frequently occur in the higher-level group.  相似文献

The efficacy of treatment with Diaform-3 antitoxin, given by either intracisternal or intralumbar injection in a dose of 400 i.u./kg, was compared in experiments on 100 rabbits with ascending, hematogenous, and cerebral tetanus caused by injection of 1 c.l.d. of tetanus toxin. Intracisternal injection of the antitoxin was found to be three times more effective than intralumbar (the proportion of animals cured was 31.4 and 10.2% respectively). The latter was effective only in animals with ascending tetanus, evidently because the portal of entry of the toxin into the CNS was along the peripheral nerves of the hind limbs.Central Research Laboratory, L'vov Medical Institute.

Effects of the regulatory peptide thyroliberin on microviscosity of lipid components of endoplasmic reticulum biological membranes in mouse hepatocytes were studied by electron paramagnetic resonance. Thyroliberin in a concentration of 10−3–10−18 M decreased microviscosity of surface layers of membrane lipids. This decrease was the most pronounced (30%) under effects of 10−10 and 10−16 M thyroliberin. Physiological effects of thyroliberin corresponded to its influence on the membrane structure.

Assessment of the aftereffects of cryoexposure and ultrahigh-frequency cryoexposure on hemangioma tissue of various types, cavernous and squamous, showed a higher cryogenic effect in hemangiomatous tissue preexposed to ultrahigh-frequency waves. A quantitative criterion is proposed for assessing the efficacy of the studied methods of exposure.
