A solid-phase radioimmunoassay (RIA) method was developed for detection of HBsAg. Its reprodu-cibility. sensitivity and specificity were evaluated, and these results were compared with the Abbott kit (AUSRIA).Horse anti-HBs was used both for coating solid phase and iodination. Normal horse serum was applied in the labelled antiserum to prevent the non-specific reaction between different species of animal sera.The cutoff was 2.21? negative control value. The factor 2.21 was derived from the mean S/N value and its 3 SD of 553 normal sera, while the factor of AUSRIA was 2.1. The lowest detectable amount of HBsAg by our RIA method was 4. 1ng/ml, while that by AUSRIA 2. 1ng/ml, which was about 2 times more sensitive than our system.The prevalence of HBsAg in normal population detected by this RIA ranged from 12.9 to 17.7%. that in the patients with acute viral hepatitis was 60.6%. and in chronic viral hepatitis patients 89.9%.As hepatitis B virus infection is quite common in our country, it is important and urgent to use RIA widely to detect HBsAg carrier in the clinical diagnosis, selection of donors and epidemiological investigation.

Objective:To summarize the allergic mechanism caused by traditional Chinese medicine injection (TCMI) to provide some references for perfecting Good Laboratory Practice(GLP) of TCMI.Method:The related iteratures in data bases at home and abroad were reviewed,and the present experimental research methods about allergies were referred to to have a view of future studies.Result:The allergic mechanism of TCMI was mostly antigen-antibody reaction, part of which was anaphylactoid reaction.The method of the evaluation of allergy caused by TCMI only was animal experiments, but there were still some allergies caused by TCMI after the evaluation with this method.The present experimental research methods indicated that the detection of mediators of inflammation and FCM(Flow Cytometry) could be used to evaluate the allergies caused by TCMI.Conclusion:More attention should be paid to allergies caused by TCMI for its complicated mechanism and frequent occurrences in clinic.It may be an effective way to evaluate the allergies caused by TCMI with several methods including in vivo and in vitro.

Objective To histomorphometricly assess changes occurred in the alveolar ridge following different methods of socket preservation and to compare them against natural healing without interventions. Methods The second、 third and fourth mandibular premolars were extracted from six beagles. Six extraction sites in each dog were randomly assigned to three treatments as follows:natural healing (T1), Bio-Oss Collagen (T2) and immediate implant with Bio-Oss (T3). Six month after surgery, the dogs were euthanized and tissue samples were sectioned, fixed and mounted, then were stained with toluidine blue. The histologic studies and morphological measurements were performed by using an optical microscope and a digital image software. Results Reabsorption in the buccal aspect of the alveolar crest of ridge was showed in all groups. With respect to the mean vertical bone loss of the buccal bone plate, T3 is lower than T1 and T2(P<0.001 ), while no significant differences were observed between T1 and T2. With regard to horizontal dimension of the alveolar process , a statistical significance could be found at 3mm and 4mm below the crest of ridge in group T1 and T3(P=0.017, P=0.042), while no statistical differences were found between other groups. Conclusions Both techniques of alveolar ridge preservation were not able to completely preserve the original bone volume after tooth extraction. Immediate implant placement in combination with Bio-Oss seems to have the potential to limit the reabsorption of the alveolar process efficiently , but the bone preserving effect of Bio-Oss Collagen is undesirable.

Objective To compare the effect of carvedilol and motoprolol on high altitude chronic congestive heart failure (CHF). Methods Ninety patients with high altitude chronic CHF were divided into three groups randomly:Twenty patients in the regular treatment group treated with angiotensin-converting enzyme inhibitor (ACEI) ,diuretics and digoxin; motoprolol (50 mg twice daily) was given in the motoprolol group( 34cases) additional to regular treatment; carvedilol (25 mg twice daily) was given in the carvedilol group(36cases ) additional to regular treatment. All the patients were followed up for six months and measured the changes of cardiac function by echocardiography. Results Left ventricular end-diastolic dimension (LVEDD) was ( 57. 3 ± 6. 5 ) mm and (57.2 ± 6. 9) mm in the carvedilol group and the motoprolol group respectively, and left ventricular end-systolic dimension (LVESD) was (46. 6 ± 7.0) mm and (44. 0 ± 6. 9 ) mm in the carvedilol group and the motoprolol group respectively, which were all significantly smaller than that in the regular treatment group ([64.7 ±9. 1]mm and [53.4 ±9.8]mm for LVEDD and LVESD,respectively) (Ps ＜0.05). Left ventricular ejection fraction (LVEF) in the carvedilol group and the motoprolol group ( [47.5 ± 8. 1] % and [52. 9 ±8.5] % ,respectively) was higher than that in regular treatment group( [42. 8 ±9. 2]% ) (Ps ＜0. 05).The improvement of LVEF in the carvedilol group was better than that in the motoprolol group (P ＜ 0. 05 ). One case died in the motoprolol group and no death in the carvedilol group,4 cases died in the regular treatment group,the mortality in the motoprolol group and the carvedilol group was significantly lower than that in the regular treatment group. Conclusion Carvedilol and motoprolol significantly improved cardiac function in high latitude CHF patients,and the effect of Carvedilol is slightly better than that of motoprolol.
