[目的]探讨吸烟对病人冠状动脉病变的影响。[方法]对吸烟组(5 0例)与不吸烟组(3 0例)进行冠状动脉造影,观察记录冠状动脉病变情况并进行统计学分析。[结果]两组冠状动脉病变记分、每日不同吸烟量与冠状动脉病变记分、不同的吸烟年限与冠状动脉病变记分比较均有统计学意义(P <0 .0 1)。[结论]长期吸烟可使冠状动脉病变程度加重,应加强对长期吸烟及冠状动脉介入术后病人的健康教育,有效预防和控制冠心病,提高人群的健康水平。 相似文献

Receiver operating characteristic curves and accuracy parameters were computed for traditional sperm characteristics (concentration, motility, morphology) and the number of peroxidase negative cells, and the concentration of adenosine triphosphate (ATP) in semen from populations of fertile and infertile men, and men who achieved a pregnancy after varicocele treatment. The percentage and concentration per millilitre of spermatozoa with rapid linear progressive motility, and the ATP concentration, provided the best discrimination between fertile and treated fertile from infertile men. The misclassification rate was higher for sperm morphology, total progressive motility and viability, whereas sperm concentration and the total sperm count per ejaculate had the worst discriminating power. The number of peroxidase negative cells per 100 spermatozoa was highly specific in identifying men who achieved pregnancy after varicocele treatment. The lower limit of normality of sperm characteristics was remarkably different between fertile men and men achieving pregnancy after treatment or during infertility work-up. 相似文献

The various causative and mechanistic phenomena associated with aneuploidy induction require considerable investigation to better understand the etiology of chromosome missegregation. We investigated the potential of vinblastine sulfate, pyrimethamine, diethylstilbestrol diphosphate, and chloral hydrate to induce numerical and structural chromosome changes in female mouse germ cells. Superovulated ICR mice were administered the compounds either by intraperitoneal injection or oral gavage, and oocytes were collected and processed for cytogenetic analysis 17 hr later. Vinblastine sulfate, administered i.p., induced a significant increase in the frequency of ovulated Ml oocytes and of hyperploid Mll oocytes compared to controls, but did not increase the frequency of structural aberrations. Pyrimethamine, diethylstilbestrol diphosphate, and chloral hydrate did not increase the frequency of numerical or structural chromosome changes in female mouse germ cells. © 1993 Wiley-Liss, Inc. 相似文献

Granulocyte elastase levels do not correlate with anaerobic and aerobic bacterial growth in seminal plasma from infertile men 总被引:2,自引:0,他引:2
Seminal culture and leucocyte elastase measurements were undertaken on samples from 30 men attending an infertility clinic. Elastase levels over 1000 ng ml-1 were obtained in 14 men and positive bacterial culture in 11 men, but there was no correlation between these two sets of measurements. While granulocyte elastase measurement in semen may reflect inflammation, our study suggests that it cannot be used as a simple marker of infection particularly in a population such as ours where the prevalence of prostatitis and genital infection is low. 相似文献

精浆抗精子抗体阳性不育患者顶体酶、一氧化氮合酶及超氧化物歧化酶活力变化的研究 总被引:2,自引:0,他引:2
目的:研究精浆抗精子抗体(AsAb)阳性对精子顶体酶、精浆一氧化氮合酶(NOS)及超氧化物歧化酶(SOD)活力的影响。方法:精浆AsAb阳性不育者40例,对照组为40例正常生育男性。通过吸光度变化分别计算顶体酶活力(BAEE/ADH联合法)、NOS活力(氧化还原反应)、SOD活力(黄嘌呤氧化酶法)。结果:精浆As-Ab阳性组与正常生育组比较,精子顶体酶活力明显降低(P<0.01),NOS活力明显升高(P<0.01),精浆中SOD活力明显降低(P<0.01)。结论:精浆AsAb阳性引起不育可能与精子顶体酶、精浆中SOD及NOS活力改变有关。 相似文献

Chest Wall Implants: Their Use for Pectus Excavatum,Pectoralis Muscle Tears,Poland's Syndrome,and Muscular Insufficiency 总被引:3,自引:3,他引:0
Darryl J. Hodgkinson 《Aesthetic plastic surgery》1997,21(1):7-15
Solid customized and prefabricated silicone implants have been used by the author for 15 years in a wide range of chest wall
deformities. Chest wall implants are often used in males seeking to augment a muscularly deficient or underdeveloped chest;
however, their greatest use has come in a variety of deformities both congenital and acquired, such as pectus excavatum, Poland's
Syndrome, and pectoralis muscle tears. The implants can be either customized using a moulage technique or are prefabricated,
manufactured implants which can be modified on the operating table to repair the contour deformity. The immediate postoperative
problem of seroma and subcutaneous implant ``show' has been minimized by careful planning, gentle technique, deep insertion,
improved patient positioning on the operating room table, and the use of oral anti-inflammatory medications. The long-term
results of these implants seem very satisfactory. The patients are usualy physically active, and the implants show no long-term
sequelae such as seroma, infection, displacement, or rupture. 相似文献

Experimental studies suggest that large numbers of chemicals, environmental and industrial pollutants affect the male reproductive system. At present, almost no information is available on the effects of these adverse agents on human reproduction. Recent reports, however, suggest that in the past 50 years male fertility has declined based on qualitative and quantitative measurements of normal sperm. This study identifies‐among the active ingredients and solvents included in pesticide formulations registered in Italy‐the chemical agents with experimental evidence of male reproductive toxicity. Documents produced by international agencies and organizations such as IARC, EPA, WHO, and original papers from the international literature were systematically reviewed. The results indicate that several pesticide products notified in the Italian Registry contain active ingredients and/or solvents severely affecting testicular function and sperm morphology in laboratory animals. Therefore, exposure to reproductive toxicants occurring among manufacturers and users of pesticide formulations registered in Italy suggest further epidemiologic surveys should be conducted in this area. 相似文献
