Methods A total of 1 147 blood samples were aerobically cultured by BACTEC 9050 in thishospital from Sept.1996 to Mar.1999.The positive rate,false-positive rate,false-negative rate and the time needed to positivity were analysed,respectively.

使用BACTEC 9050全自动血培养仪对1 147例血标本进行需氧培养，分析阳性率、检出菌的种类、阳性检出时间、假阳性和假阴性。

This method inhibits the growth of gram-positive and gram-negative microorganism, e.g., S. aureus, S. epidermidis, K. pneumoniae, E. aerogenes, and E. cloacae.

该方法抑制了革兰氏阳性和革兰氏阴性微生物的生长，例如金黄色葡萄球菌、表皮葡萄球菌、肺炎克雷伯氏菌、产气肠杆菌和阴沟肠杆菌。

Information was available on ammelide and ammeline in 20 samples; 18 samples were negative and two were positive for both compounds.

信息可在ammelide和ammeline在20个样品； 18个样本均呈阴性反应，两人都积极的化合物。

Two samples were positive for cyanuric acid (2.11 and 2.63 ppm), one was positive for ammelide (13.9 ppm), and all other results were negative.

两个样品呈阳性反应，氰尿酸（ 2.11和2.63百万分之一），一个是积极的ammelide （ 13.9分钟），和所有其他结果均为阴性。

The follicles were lined by cells with moderate amphophilic to eosinophilic cytoplasm with round nuclei and occasional prominent nucleoli.

瘤组织与甲状腺球蛋白、甲状腺转录因子1及其他常用于肾病鉴别诊断的免疫标记反应都为阴性。

结果 妊高征组胎盘绒毛和子宫胎盘床血管壁IgA、IgG、IgM和C3的阳性表达率胎盘绒毛：20.1%，24.1%，72.4%和65.5%；胎盘床：20.0%，20.0%，70.0%和60.0%）均分别显著高于对照组(P＜0.05，而对照组均呈阴性表达。

Exfoliated cells from nasoparynx of patients with definite or suspected nasopharyngeal carcinoma were examined for EBNA by anticomplement immunoenzymatic method.

本文用抗补体免疫酶法检查鼻咽部脱落细胞的EBNA，结果①79例鼻咽癌病人全部阳性，其阳性检出率比细胞学(87.3％)和组织学(91.1％)方法高；②4例初次检查EBNA阳性，但细胞学和组织学阴性者，3个月内复查也找到癌细胞；③18例头颈部其他肿瘤病人和21例胎儿全部阴性，并为细胞学和组织学方法所证实。

Results The incidence of SBP in patients with Hepatocirrhosis was 39.6%. The Gram negative bacilli were bacteria.
