利多卡因宫旁阻滞麻醉在人工流产中的应用

人工流产手术虽然时间短,一般不需麻醉,但毕竟是手术操作,也给受术者带来一定的痛苦[1]。患者由此产生恐惧心理,甚至发生人流综和症等一系列并发症。我院门诊针对这种情况在人流手术中采用利多卡因宫旁阻滞麻醉,取得良好效果,现报道如下。1资料与方法1.1一般资料2005年3月至200

头胸导联、常规导联心电图诊断冠心病的比较——与冠脉造影结果对照

同步记录72例拟诊冠心病患者头胸导联(HC)及常规导联(wilson)心电图(ECG),并与冠脉造影结果对照。结果:HC与Wilson导联ECG对冠心病诊断的敏感性分别为88.9％与81.5％,特异性33.3％与27.8％,准确性75％与68.1％;二组导联对比无明显差异(P>0.05);对右心室梗塞、缺血及左心室后壁缺血.HC导联的敏感性(91.7％)及准确性(94.4％)均显著高于Wilson导联(12.5％、70.8％,P<0.01),并与冠状动脉病变程度呈高度正相关。HC导联优于Wilson导联。     

Mid-p confidence intervals for the poisson expectation

Conventionally a confidence interval (CI) for the standardized mortality ratio is set using the conservative CI for a Poisson expectation, μ. Employing the mid-P argument we present alternative CIs that are shorter than the conventional ones. The mid-P intervals do not guarantee the nominal confidence level, but the true coverage probability is only lower than the nominal level for a few short ranges of μ. The implications for mid-P confidence intervals of various proposed definitions of two-sided tests for discrete data are discussed.     

Application of enzyme linked immuno-electrophoresis for the diagnosis of tuberculosis]

The technique of Enzyme linked immuno-electrophoresis (ELIEP) was established to detect the specific antibody against tubercle bacilli. The results of 730 cases showed that the sensitivity of this method is 97.33%, and the specificity, 97.5%. Thus this method is more sensitive than the ELISA methods which had bean published. The manipulation of ELIEP is simple, convenient, and fast, reagent stable. This method may be used in diagnosis of tuberculosis with reliability and efficiency.     

喉癌患者染色体对致突变剂诱发畸变的敏感性研究

采用平阳霉素作为诱变剂，对２８例喉癌患者和２３例正常人做外周血淋巴细胞染色体对诱变剂敏感性研究，结果显示喉癌患者的染色体总畸变率、每细胞染色单体断裂率（ｂ／ｃ值）和细胞畸变率分别为１．９８％±０．０５％，０．５７％±０．３５％和４２．８％±１２％。正常人则分别为０．９４％±０．０４％，０．２８％±０．１２％和２７％±１２％。经统计学处理，喉癌患者组与正常人组的差异有高度显著性。并结合实验结果探讨了染色体对致突变剂的敏感性与患喉癌风险的关系。     

Immunoscintigraphy in the detection of tuberculosis with radiolabelled antibody fragment against Mycobacterium bovis bacillus Calmette-Guérin: a preliminary study in a rabbit model.

Immunoscintigraphy with radiolabelled monoclonal antibodies is widely used to detect solid tumours, but only a few trials have been carried out concerning the specific in vivo localization of an inflammatory process. The purpose of this study was to investigate the detectability of tuberculous foci utilizing this method with radiolabelled bacillus Calmette-Guérin (BCG)-specific F(ab')2 in rabbits. All of the tuberculous lesions (n = 8) were clearly visualized on serial scintigraphy for up to 48 h after injection of the antibody. Immunohistochemical and Ziel-Neelson staining of the tuberculous lesions confirmed the presence of the tuberculous antigens and bacilli. It failed to demonstrate any sustained retention of the BCG-specific antibody fragment in the control group with syphilitic orchitis (n = 2). Therefore, the specific in vivo localization of tuberculosis is feasible by immunoscintigraphy.     

Differential sodium fluoride sensitivity of alpha-naphthyl acetate esterase in human, bovine, canine, and murine monocytes and lymphocytes.

The sensitivity of alpha-naphthyl acetate esterase (ANAE) activity of human, bovine, canine, and murine leukocytes to low (42 micrograms/ml incubation mixture) and high (1.5 mg/ml incubation mixture) concentrations of sodium fluoride (NaF) was compared. The ANAE activity of bovine and canine monocytes was only slightly inhibited by the low concentration of NaF, whereas that of murine peritoneal macrophages was moderately inhibited and that of human monocytes was completely inhibited. Human and canine monocytic ANAE was completely inhibited by the high concentration of NaF, whereas the ANAE activity in 1% of bovine monocytes and murine peritoneal macrophages was not inhibited. The ANAE activity of human and murine lymphocytes in nonenriched venous blood samples showed no or negligible NaF sensitivity to the low concentration of NaF, whereas bovine lymphocytic ANAE showed slight and canine lymphocytic ANAE moderate NaF sensitivity. The ANAE of murine T-lymphoma L5178Y cells was resistant to the low concentration of NaF, but the ANAE of both murine T-lymphoma L5178Y cells and murine lymphocytes was completely inhibited by the high concentration of NaF. Human, bovine, and canine lymphocytic ANAE showed marked NaF sensitivity toward the high concentration of NaF, showing 73%, 86%, and 93% inhibition, respectively. The neutrophils in murine venous blood and ascites were positive for ANAE activity, which was only slightly inhibited by the low concentration of NaF but completely inhibited by the high concentration. Results of this investigation demonstrate that the ANAE of leukocytes of various species show remarkable differences in its sensitivity to low and high concentrations of NaF, indicating that appropriate concentrations of NaF are required for distinguishing the ANAE of lymphocytes and monocytes of different species.
