BACKGROUND: +Gz-induced acute dysencephalia and its protection is one of the significant topics in Aero-medical researches. Its pathological mechanism, however, is still unclear and protective measures should be developed further. OBJECTIVE: To observe the expression of inducible nitricoxide synthase (iNOS) in brain tissue after +Gz exposure and to analyze the protective effects of danshen and basic fibroblast growth factor (bFGF) on repeated +Gz exposure-induced brain injury. DESIGN: Randomized controlled animal study. SETTING: Researching Center of Molecular Biology, Air-force General Hospital of Chinese PLA.MATERIALS: The experiment was carried out at the Researching Center of Molecular Biology, Air-force General Hospital of Chinese PLA from April to August 2000. A total of 20 healthy SD rats of clean grade were divided into 5 groups according to randomly digital table, including control group, +Gz exposure group, bFGF group, danshen group and saline group with 4 in each group.METHODS: All rats were fixed on rotatory arm of centrifugal apparatus,and their heads were towards core of the apparatus. Except the rats in control group, the value of +Gz exposure was +14 Gz, and the growth rate was 1.5 G/s. The exposure at peak value lasted for 45 s. +Gz exposure was done for three times, and the interval was 30 minutes. Rats in the control group were also treated with the same +Gz exposing procedure, but the G value was +1 Gz. Rats in bFGF group and danshen group were intraperitoneally injected with 100 μg/kg of bFGF and/or 15 g/kg of danshen solution, respectively, at 30 minutes before centrifugation and immediateness after centrifugation; moreover, rats in saline group were injected with the same volume of saline. Six hours after exposure, rats were cut off their heads to obtain the brains which were maintained in liquid nitrogen for RNA extraction. The expression of iNOS mRNA in brain tissues of the rats in each group was detected with semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and calculated on the basis of ratio between iNOS and glyceraldehyde-3-phosphate dehydrognase.MAIN OUTCOME MEASURES:Expressed level of iNOS mRNA in brain tissue of rats.RESULTS: Expression of iNOS mRNA in brain tissue was higher in repeated +Gz exposure group than that in control group (0.452 ±0.014,0.065±0.008, P ＜ 0.01); however, that was lower in bFGF group and dan-shen group than that in +Gz exposure group (0.196±0.010, 0.183±0.011,0.452±0.014, P ＜ 0.01).CONCLUSION: Repeated +Gz exposure can increase the expression of iNOS mRNA, this plays an important role in cerebral injury induced by repeated +Gz exposure. Moreover, bFGF and danshen have protective effects on cerebral injury induced by +Gz exposure.

Objective　To explore the role of acute infection of Chlamydia pneumoniae (Cpn) in respiratory diseases. Methods　Microimmunofluorescence test was used to detect IgG antibodies for Cpn in serum obtained from 93 inpatients and PCR was used to test Cpn in detection of Cpn DNA in throat specimens from 55 of the 99 patients. Results　Acute Cpn infection was diagnosed in 35.5% of the respiratory diseases. Antibodies for Cpn (titer of ≥512) were present in 47.6% of the pneumonia group, which may suggest that during 1998 to 1999, Cpn caused an epidemic in Beijing. They were also present in 50% of asthma group, 50.0% of pulmonary heart disease group and 26.3% of lung cancer group. Only five patients (9.1%) were positive by PCR. There exists discrepancy between serological and PCR results. Conclusion　Detection of IgG antibodies for Cpn conduces to diagnosis of acute Cpn infection and give advice for appropriate therapy.
