  transitional cell neoplasms
Transitional cell neoplasms developed and a positive dose response relationship was observed.
      
There were no tubular cell or transitional cell neoplasms of the kidney in female rats.
      


Experimental bladder tumors were induced in female mice by intravescical infus- ion of N-methyl-N-nitro-N-nitrosoguanidine.Early changes in the bladder epithelium of mice were studied.Our observations show that the lesions have a typical course of hyperplasia,noninvasive papilloma and invasive carcinoma and the tumors consist of transitical cells.

本项研究采取膀胱灌注 MNNG 诱发小鼠膀胱肿瘤,对 MNNG 引起膀胱上皮早期病变进行了动态观察。肿瘤的发生,发展经历了从单纯增生,乳头状,结节状增生,良性乳头状瘤,非浸润癌浸润癌这样一个典型的病理过程。诱发的膀胱肿瘤均为移行细胞肿瘤

bcl 2 expression was detected in 6 normal bladder mucosa,6 hyperplastic inflammatory bladder mucosa,6 papiloma of bladder and 45 transitional cell carcinoma of bladder by means of flow cytometry and cytoimmunofluorescence staining using anti bcl 2 polyclonal antibody bcl 2(N 19).The positive expression rate in these 4 groups was 33.3%,50.0%,83.3% and 100.0% respectively.It was significantly higher in the tumor groups ( P <0.001) but was not related to the tumor grade and stage and prognosis ( P >0.05)...

bcl 2 expression was detected in 6 normal bladder mucosa,6 hyperplastic inflammatory bladder mucosa,6 papiloma of bladder and 45 transitional cell carcinoma of bladder by means of flow cytometry and cytoimmunofluorescence staining using anti bcl 2 polyclonal antibody bcl 2(N 19).The positive expression rate in these 4 groups was 33.3%,50.0%,83.3% and 100.0% respectively.It was significantly higher in the tumor groups ( P <0.001) but was not related to the tumor grade and stage and prognosis ( P >0.05) denoting that abnormal bcl 2 expression might play a promotive role in the tumorigenesis and tumor development of bladder tumors.

为探讨bcl2基因蛋白在膀胱移行细胞和移行细胞肿瘤中表达程度的差异及该蛋白表达与移行细胞癌病理分级、临床分期和预后的关系,用抗体bcl2(N19)及流式免疫学技术对6例正常膀胱粘膜、6例炎性增生粘膜、6例乳头状瘤和45例移行细胞癌的bcl2蛋白表达进行了定量分析。结果表明:bcl2蛋白在4种组织标本中均表达,阳性率分别为33.3%、50.0%、83.3%、100.0%。FI值呈移行细胞癌>乳头状瘤>炎性增生粘膜>正常粘膜。肿瘤组bcl2蛋白表达显著高于非肿瘤组(P<0.001)。在膀胱移行细胞癌中bcl2蛋白的表达程度与肿瘤病理分级、临床分期和预后无关(P>0.05)。提示bcl2蛋白的异常表达可能在膀胱移行细胞肿瘤发生、发展中起着促进作用。

Objective To study the relationship between the expression of Ki-67, Bcl-2 and EMA and biological behavior of bladder tumor. Method Using an immunohistochemical method (LSAB), the expression of Ki-67, BcL-2 and EMA in formalin-fixed paraffin-embedded sections of tumor tissues were detected in 49 patients with bladder cancer. Result Ki-67 labeling index was associated with the proliferation of tumor cells in grade 0, Ⅰ,Ⅱ but in grade Ⅲ (P < 0. 01 ). It is unreliable to represent the proliferation of tumor by...

Objective To study the relationship between the expression of Ki-67, Bcl-2 and EMA and biological behavior of bladder tumor. Method Using an immunohistochemical method (LSAB), the expression of Ki-67, BcL-2 and EMA in formalin-fixed paraffin-embedded sections of tumor tissues were detected in 49 patients with bladder cancer. Result Ki-67 labeling index was associated with the proliferation of tumor cells in grade 0, Ⅰ,Ⅱ but in grade Ⅲ (P < 0. 01 ). It is unreliable to represent the proliferation of tumor by the Ki-67-positive incidence in grade Ⅲ. Statistical correlation existed between age factor and the level of Bcl-2 expression except for the other tumor background parameters (P < 0. 05). The frequency of EMA-positive cells was decreased with the increase of the tumor grades and stage (P < 0. 01 and P < 0. 05, respectively). Conclusion The expression of the three antigens can show the biological behavior of bladder turmor in some aspects. EMA is closely related to the biological behavior of bladder tumor. It is an essential marker for judging the malignancy and prognosis of bladder tumor.

目的研究Ki-67、Bcl-2和EMA在膀胱肿瘤细胞中的表达及其与肿瘤细胞生物学行为的关系。方法用免疫组化技术(ISAB法)检测Ki-67、Bcl-2和EMA在膀胱移行细胞肿瘤标本中的表达。结果Ki-67标记表达率与肿瘤细胞的增殖率有关(除Ⅲ级肿瘤),P<0.01。在Ⅲ级肿瘤中用Ki-67标记率代表肿瘤的增殖活性不可靠。各种肿瘤参数中只有年龄因素与Bcl-2的表达水平有统计学上的相关性,P<0.05。EMA的表达率随着膀胱肿瘤组织学分级和分期的增加而降低(P<0.01,P<005)。在复发和多发肿瘤中EMA的表达率亦较低(P<0.01)。结论三种抗原均可从某些方面反映出膀胱肿瘤的生物学行为。但只有EMA与膀胱肿瘤的生物学行为关系密切,可作为判定膀胱肿瘤的恶性程度和愈后的重要标记物。
