幽门螺杆菌甲硝唑耐药与细菌定植密度的研究

目的：研究H.pylori对甲硝唑耐药与细菌定植密度问的关系．方法：用E-test方法检测109株H.pylori菌株对甲硝唑的敏感性；胃粘膜活检标本经Warthing-Starry染色后观察评定H.pylori定植密度．结果：109株H.pylori菌株的甲硝唑耐药率为67．89％；H.pylori定植密度的不同等级在H.pylori菌株甲硝唑耐药率上无显著性差异．结论：H.pylori对甲硝唑的敏感性与细菌定植密度无关．     

肝炎患者血清脯氨酸肽酶活性测定的临床意义

检测５６例肝炎患者血清脯氨酸肽酶（ＰＬＤ）、ＡＬＴ、ＡＬＢ、ＴＰ、ＴＢｉ、ＨＡ。结果急性肝炎（ＡＨ），慢迁肝（ＣＰＨ），慢活肝（ＣＡＨ）的血清ＰＬＤ均显著高于对照组（Ｐ＜０．０１），ＡＨ恢复期ＰＬＤ略升高，ＡＨ组中有ＴＢｉ者ＰＬＤ高于无ＴＢｉ者（Ｐ＜０．０５），ＡＨ组ＰＬＤ与ＡＬＴ呈正相关、ＣＰＨ、ＣＡＨ组中ＰＬＤ与ＡＬＢ呈负相关，结果表明ＰＬＤ是急性肝细胞损害的一种指标，同时对慢性肝病的判断更具有重要意义，可作其随访指标。     

中西医结合促排卵疗效分析

在女性不孕症中，下丘脑—垂体—卵巢轴功能失调致排卵障碍为不孕症主要原因之一，传统多采用克罗米酚、人绒毛膜促性腺激素（ＨＣＧ）、雌—孕激素序贯疗法等促排卵，虽有一定疗效，但妊娠率较低［１］，我院不孕症专科门诊自１９９６年９月至１９９８年３月采用中西医结...

THE RISK OF OCCUPATIONAL LEAD EXPOSURE

We conducted a field survey on 53 workers in a battery factory, 52 solder workers, and 50 embroidery workers (control group). The average air lead levels at the workplaces of these three groups were 0.578 mg/nt, 0.0015 mg/m:3 and 0.006 mg,iml respectively. Clinical and biochemical studies re vealed that the workers in Shanghai Navigation Battery Factory were affected somewhat by the toxic effects of lead. The solder workers showed no signi- ficant abnormalities compared with the control group. A significant dose-response relationship ex isted between air lead levels and toxic effects. The early clinical manifestations observed were dysfunction of the central nervous system, dyspcpsia, joint pain, and myalgia in the extremities. A positive association was observed between the prevalences of fatigue, mild abdominal pain, and joint pain and the blood lead (PbB), urine lead (PbU), and zinc protoporphyrin (ZPP) levels. The symptomatic threshold values for PbB, PbU, and ZPP were 30 u.g/dl, 0.045 mg/'I, and 40 Ug/dl, respectively Although the PbB, PbU, 6-aminolevulinic acid dehydratase (ALAD), free erythrocyte protoporphyrin (FEP), and ZPP levels could be used as criteria of lead exposure, the measurement of ZPP is the first- choice screening test for a preventive monitoring program. The motor and sensory conduction velocities in the median nerve were slower in the exposure group than the control group (p<0.05). Conduction velocity and intensity of lead exposure were not significantly correlated. No apparent effects on behavioral func tion were observed among the solder workers.
