人精液中ABH血型物质分泌强度的研究

本文采用中和试验、沉降反应和解离试验对１３５例已知血型人精液中ＡＢＨ血型物质的分泌强度进行了检验，并将其分为强、中、弱三型。这对区别个人血型物质含量及性犯罪的法医学鉴定均有重要意义。并证明了ＡＢ型人精液中Ａ、Ｂ血型物质含量不均等现象，并且绝大多数人Ｂ型物质高于Ａ型物质。     

顺铂对结直肠癌肿瘤浸润淋巴细胞杀伤活性的影响

为在临床选择有效的免疫化疗方案提供一定的理论依据，作者以结直肠癌肿瘤浸润淋巴细胞（ＴＩＬ）和顺铂（ＣＤＤＰ）为研究对象，对１６名手术治疗的结直肠癌患者，分别观察ＣＤＤＰ体内注射及体外预处理ＴＩＬ和Ｒａｊｉ细胞对ＴＩＬ表面标志和杀伤活性的影响。流式细胞仪检测结果显示，静脉注射ＣＤＤＰ能增加结直肠癌ＴＩＬ中ＣＤ３＋／ＣＤ４＋和ＣＤ３＋／ＣＤ８＋细胞含量，同时增强ＴＩＬ体外杀伤Ｒａｊｉ细胞的活性；而体外以ＣＤＤＰ处理Ｒａｊｉ细胞能增强其对结直肠癌ＴＩＬ杀伤的敏感性。作者认为，对于联合应用ＴＩＬ和ＣＤＤＰ治疗结直肠癌的临床效果有必要进一步研究。     

The correlation of ureaplasma urealyticum infection with infertility

Summary. A prevalence study of Ureaplasma urealyticum (UU) infection of the male genital tract was carried out in Shanghai between March 1992 and June 1995. Significantly higher frequency of UU infection was found among infertile males (549/1416) as compared to fertile controls (34/375). Examination of 8 specimens each from infertile men and fertile subjects by electron microscopy, immunogold and immunofluorescence techniques, demonstrated adhesion of Ureaplasma urealyticum to the membrane of spermatozoa and exfoliated germ cells. In addition, gold particles on Ureaplasma urealyticum were found to be adhered to the sperm surface in 4 of the 8 samples. Strong specific anti-UU fluorescence was detected in 6 of 8 samples, mainly on the midpieces and post-acrosomal regions of the spermatozoa.
To further study the effects of Ureaplasma urealyticum on fertility, 47 male Sprague-Dawley (SD) rats were infected artificially with Ureaplasma urealyticum serotype 8 (T960). Morphological changes in the seminiferous tubules were observed 3–5 weeks after inoculation in the sacrificed animals. Dramatic impairment of spermatogenesis of both testes was found in 11 rats. Mating experiment confirmed infertility in 12 of 40 rats. Offsprings of the infected rats were significantly smaller than those of controls in terms of prenatal weights and birthweights.

Relationship between refractive error and monochromatic aberrations of the eye.

PURPOSE: To examine the relationship between ametropia and optical aberrations in a population of 200 normal human eyes with refractive errors spanning the range from +5.00 to -10.00 D. METHODS: Using a reduced-eye model of ametropia, we tested the hypothesis that the optical system of the eye is uncorrelated with the degree of ametropia. These predictions were evaluated experimentally with a Shack-Hartmann aberrometer that measured the monochromatic aberrations across the central 6 mm of the dilated pupil in well-corrected, cyclopleged eyes. RESULTS: Optical theory predicted, and control experiments on a model eye verified, that Shack-Hartmann measurements of spherical aberration will vary with axial elongation of the eye even if the dioptric components of the eye are fixed. Contrary to these predictions, spherical aberration was not significantly different from emmetropic eyes. Root mean square of third-order aberrations, fourth-order aberrations, and total higher aberrations (third to 10th) in myopic and hyperopic eyes were also uncorrelated with refractive error. Astigmatic eyes tended to have larger total higher-order aberrations than nonastigmatic eyes. CONCLUSIONS: We conclude that a reduced-eye model of myopia assuming fixed optical parameters and variable axial length is not tenable.
