312例活动性肺结核延误诊断的临床分析

本文报告1986年12月至1988年5月在我科门诊确诊的312例新发现活动性肺结核延误诊断情况。结果表明,新发现活动性肺结核的及时诊断率为67.1％,总延误率为32.9％,平均延误时间为75天。提示我区肺结核的延误诊断情况较严重。如能采取多方面综合性措施,结核病的发现问題可望有所好转。     

不同培养基对肠球菌检出率的影响

用pH9.6葡萄糖肉汤、6.5％NaCl琼脂平板、3％—5％羊血琼脂平板三种不同培养基,从同一份样品中分离肠球菌,检出率有显著差别。pH9.6葡萄糖肉汤对检样选择性增菌后,再用6.5％NaCl琼脂平板分离肠球菌,其检出率明显高于现正普遍用于肠球菌初代分离的3％～5％血琼脂平板(P<0.05),也高于单纯使用6.5％NaCl琼脂平板(P<0.05);后两者间无显著差别(P>O.05)。属中种的构成在不同培养基上检出情况也不同。 关键词:培养基 肠球菌 检出率 肠球菌广泛存在于自然界,是水、空气、尘     

转铁蛋白受体单抗WuT9导向治疗晚期肝癌

应用转铁蛋白受体单抗WuT9对晚期肝癌进行了临床研究，4例进行了放射免疫显像检查，22例进行了临床治疗观察。结果表明：（1）4例显像检查病人中，有3例肿瘤于注射^131I-WuT9偶联物后第7天呈清楚显像；（2）22例接受阿霉素－WuT9偶联物治疗后，近期疗效观察：18例有效，7例显效，远期随访2年者15例，4例存活，其中2例存活已4年；对照组10例，有效仅3例，无显效，无1例存活2年。     

丙型肝炎患者外周血单核细胞中丙型肝炎病毒复制的研究

９例临床诊断为丙型肝炎患者，研究其外周血单核细胞中ＨＣＶＲＮＡ的存在及复制。９例患者血清标本抗－ＨＣＶ及ＨＣＶＲＮＡ均为阳性，采用高敏感的逆转录一套式ＰＣＲ法测定其外周血单核细胞中ＨＣＶ正、负链ＲＮＡ，结果９例患者外周血单核细胞中７例ＨＣＶ正链ＲＮＡ阳性，３例ＨＣＶ负链ＲＮＡ阳性，证实部分丙肝患者外周血单核细胞中存在ＨＣＶ的复制，表明肝细胞并非为ＨＣＶ感染与复制的唯一场所。     

二阶导数光谱法测定尿中呋喃妥因浓度

本文采用有酸性条件下用乙酸乙酯萃取呋喃妥因后，通过二阶导数光谱法测定尿中呋喃妥因的浓度。该法定量信息为３７４￣３７７ｎｍ处的峰谷之间距离，最低检出浓度为１．５ｍｇ／Ｌ，回收率为９８％，相对标准差小于３％；本法与ＨＰＬＣ法进行了对照性研究。两法具有明显的相关性（ｒ＝０．９９９１）。本法可用于呋喃妥因药动学的研究。     

Chromosomal screening of mentally retarded school children in Taipei.

The major concern of the national population policy in Taiwan in recent years has been to lower the incidence of hereditary diseases and mental retardation in the general population. It has been estimated that there are around 10,000 mentally retarded school children in Taiwan. If effective chromosomal screening can be extended to these children, some of the family members who are carriers of balanced chromosomal rearrangements may benefit from follow-up studies and genetic counseling. The present report is the result of a pilot study conducted from 1988 to 1991 to explore the possibility of chromosomal screening of mentally retarded school children in Taipei. A total of 871 blood samples were collected from 1,147 children registered in 46 schools or residing in homes for the retarded. Chromosomal analysis was successfully accomplished on 674 out of 871 blood samples. The following chromosomal abnormalities were observed: 28 Down's syndrome, four Klinefelter syndrome, one XYY, one triple X, 11 translocations, seven inversions, four mosaics, three duplications, one deletion and one with an extra marker chromosome. After follow-up cytogenetic analyses of 13 families with probands with structural chromosomal anomalies, three of these families were shown to have one or two carriers of balanced translocated chromosomes. It seems that the present screening system would not be practical or cost-effective if it were applied island-wide in the future.     

Characterisation of passively transferred antigen arthritis induced by methylated bovine serum albumin in the rat: effect of FK 506 on arthritis development.

The conditions necessary for the passive transfer of antigen arthritis induced by methylated bovine serum albumin (mBSA) in the rat have been studied. Spleen cells from immunised rats were not capable of transferring disease unless they were first activated in culture with mBSA or concanavalin A. Cells from sham-immunised animals could not be activated to transfer the arthritis. The immunosuppressant drug FK 506 could inhibit the development of the arthritis when present during the activation period in culture or when dosed to the recipients of activated cells.     

Segmental fixation with U-shaped rod in the treatment of spondylolisthesis

Summary From 1987 to 1990 the authors treated 20 cases of spondylolisthesis by an improved operative procedure including excision of the medial part of the superior articular processes of the slipped vertebra, excision of the soft tissue between the ununited isthmi, and excision of the ligamentum flavum between the intervertebral space above the slipped segment. In some instances the lower portion of the lamina over the slipped vertebra should be resected. A U-shaped rod was used to hold sublaminar fixation of two segments above and below the slipped vertebra, with the slipped vertebra spared. Utilizing the U-shaped rod as support, bone strips were placed along the lateral and anterior sides of the rod to bridge the gap between the laminae of the displaced vertebra. Other bone grafts were focused on the facet joints. The patients were allowed ambulation early postoperatively. 19 cases could be evaluated at preliminary follow-up. All showed satisfactory results.     

Phase II study of high-dose ifosfamide in hepatocellular carcinoma

Summary A phase II study of high-dose ifosfamide in hepatocellular carcinoma was conducted among 17 Chinese patients. The dose of ifosfamide used was 2.5 g/m² daily given as a continuous infusion for 5 days. In all, 15 patients were evaluable for tumour response. There was no complete or partial responder. The treatment was well tolerated. The most frequent toxicity was alopecia, which occurred in 11 patients, and 5 patients developed mild haematological toxicity. There was no evidence of liver or bladder toxicity. Overall, 14 patients were evaluable for survival. The median survival was 92 days (range, 30–568 days). We conclude that high-dose ifosfamide is well tolerated but ineffective in hepatocellular carcinoma in Chinese patients.
