Using the cell-mediated lympholysis (CML) technique, we studied lymphocytes of six individuals with discrepancies between the karyotypic and phenotypic sex.
      
The masculinized females are considered to be intersexes (phenotypic sex determination).
      
Postnatal phenotypic sex differentiation has been investigated in a laboratory marsupial, Monodelphis domestica, as part of a larger study to resolve apparent discrepancies between eutherian and marsupial mammals.
      
Pole cell transplantations between male and female embryos yielded completely fertile heterosexual germ-line mosaics thus demonstrating phenotypic sex reversal of donor germ cells in a host of the opposite sex.
      
Sex reversed mice (Sxr) show a DNA arrangement of these sequences in conformity with their phenotypic sex, suggesting that this DNA is closely connected with the determination of sex.

Normal sexual development is the consequence of three sequential interrelated processes: establishment of genetic, gonadal and somatic sex.
      
Normal male sexual development comprises three sequential steps: the development of genetic, gonadal and somatic sex.

In all non-drosophilid fly species examined, Sex-lethal (Sxl), the master switch at the top of the Drosophila hierarchy, does not control somatic sex.
      
This rapid divergence contrasts with the apparently deep conservation of dsx, which in Drosophila controls virtually all aspects of somatic sex except for male courtship behavior (which is controlled by fru).

为了进一步探讨性别异常发生的机制及染色体组型与表型性别的相关性 ,对 33例性别异常病人的染色体组型和临床资料进行分析。结果表明 :46XY男性假两性畸形占 5 7 5 7% ,46XX女性假两性畸形为 18 18% ,真两性畸形的组型有12 12 % ,其他组型为 12 12 %。含Y染色体组型的病人 88 8%可以找到睾丸 ,但 73 6 8%的病人表现为女性社会性别。性染色体与社会性别的相符率为 42 82 %。还发现 2例男性假两性畸形其性染色体正常 ,但常染色体分别为臂间倒位及 13和 14号染色体间的易位时 ,也可以导致性别异常。结论 :性染色体决定着性腺分化的方向 ,但成熟的性腺和正常的性别发育还需除性染色体之外的多条染色体、多个基因的参与。

Objective To study the clinicophatological features of Non-Hodgkin's lymphoma in children and the relationship of LMP-1 and p53、 bcl-2 protein expression. Methods The expression of P53、bcl-2、LMP-1 protein in children's NHL were detected with immunohistochemical method. Results The expression of P53 were detected in 39(60. 9%) of 64 cases of NHL in children, which positively correlated with the aggressiveness of lymphomas. And there was a great significance between the expression of P53 in lowly aggressive lymphoma...

Objective To study the clinicophatological features of Non-Hodgkin's lymphoma in children and the relationship of LMP-1 and p53、 bcl-2 protein expression. Methods The expression of P53、bcl-2、LMP-1 protein in children's NHL were detected with immunohistochemical method. Results The expression of P53 were detected in 39(60. 9%) of 64 cases of NHL in children, which positively correlated with the aggressiveness of lymphomas. And there was a great significance between the expression of P53 in lowly aggressive lymphoma and in intermediately aggressive lymphoma and highly aggressive ones. The expression of bcl-2 were detected in 37 (53. 8%) of 64 cases, the expression of bcl-2 was higher in BCL than TCL, in low-grade than high-grade lymphoma. (4) The protein of LMP-1 was positive in 45/64 cases of NHL, and the expression closely correlated with the aggressiveness and age of cases, but has no pertinence the immune phenotype,gender and lesion site of NHL. However, the expression of LMP-1 were positively relevant to the expression of P53 and bcl-2 in NHL. Conclusion The infection of EBV might still play an important role in the pathogensis and development of NHL in children, mainly through inducery the overexpression of P53 and bcl-2.

目的 探讨儿童NHL EB病毒LMP-1和P~(53)、bcl-2蛋白的表达及关系。方法 采用免疫组化Envision法检测64例儿童NHL中LMP-1和P~(53)、bcl-2蛋白。结果(1)P~(53)蛋白阳性表达39例(60.9%),表达强度与淋巴瘤恶性程度呈正相关;阳性表达率在低恶组与中、高恶性组间有显著性意义,P<0.01。bcl-2蛋白阳性表达37例(53.8%),bcl高于TCL,低恶性高于高恶性。(2)LMP-1蛋白阳性表达45例(70.3%),阳性表达率与肿瘤恶性程度和年龄有统计学意义,P<0.01;而与淋巴瘤免疫表型、性别和发病部位无关。LMP-1表达与P~(53)及bcl-2的表达呈正相关。结论 EBV感染是儿童NHL发生发展不可忽视的病毒致病因素,其致病作用可能是通过上调P~(53)、bcl-2蛋白实现的。

Fourty four nike red chicken were used to studry sex identification by preparing chromosomes with the techniques of direct pulp, modified direct marrow, marrow short term incubation and C-banding. The results showed that:(1)many microchromosome were darkstained C-bands, and all W-chromosomes had ones wholly dark-stained with good repetition, but macrochromosomes had very light C-bands or not at all. (2)Being treated by C-banding technique, a totally dark-stained W-chromosome showed up in the metaphase configuration...

Fourty four nike red chicken were used to studry sex identification by preparing chromosomes with the techniques of direct pulp, modified direct marrow, marrow short term incubation and C-banding. The results showed that:(1)many microchromosome were darkstained C-bands, and all W-chromosomes had ones wholly dark-stained with good repetition, but macrochromosomes had very light C-bands or not at all. (2)Being treated by C-banding technique, a totally dark-stained W-chromosome showed up in the metaphase configuration of the femal, which was easily identifiable, but did not in the male′s. It indicates that C-banding technique offers an effective approach to sex identification of the avian. (3)C-banding offers a simple and practical approach to identify W-chromosome which is heteromatic, the sexing results by C-banding were completely the same as they actually are. (4)The combination of the technique of direct feather pulp or marrow short term incubation with C-banding would be a no invasive approach to sex identification of the rare and extincting avian.

以引进品种尼克红鸡为研究对象 ,用羽髓法和改进的骨髓法制备染色体并对其进行 C分带处理 ,依据 C带 W染色体的存在与否 ,对 32只尼克红鸡进行了性别鉴定。结果表明 :(1 )尼克红鸡染色体经 C分带处理 ,很多微小染色体均显出深染的 C带 ,W染色体则整条深染 ,而且重复性很强 ,但大型染色体没有或仅显示很浅的 C带 ;(2 )母鸡的中期分裂相中可见到 1条完全深染的 W染色体 ,公鸡的中期分裂相中则否 ;(3) C分带技术为禽类异染色质 W染色体的识别提供了简便易行的手段 ,依此对 4 4只尼克红鸡判定的性别与这些供体鸡表型性别的符合率为 1 0 0 %;(4)应用直接羽髓法或骨髓短期孵育法制备染色体 ,结合 C分带处理 ,是一种可望用于珍稀和濒危禽类性别鉴定的非侵害性方法
