Single saturating dose (SSD) assay for the distribution of androgen receptor (AR),oestrogen receptor(ER),progesterone receptor(PR),and epidermal growth factor receptor (EGFR) between transition zone and peripheral zone of prostate was carried out in 22 samples from 11 patients with BPH.The results showed that AR was positive in all the 22 samples and its level was higher than that of PR and ER in every sample.Although the levels of AR varied from patient to patient,the concentration of AR between transition zone and peripheral zone had a close correlation ( P <0.001).The level of AR was higher in peripheral than transition zone.There was no difference between two zones in the levels of PR and ER.As to EGFR,it was significantly higher in transition zone than peripheral zone.The difference of zonal distribution of receptors in prostate might suggest the varying dependence of prostate to androgen,oestrogen,EGF,and other factors.

Transrectal ultrasonographic features of prostate in BPH were studied in 563 patients with the volume of the whole prostate and the transitional zone measured and in 45 the actual weight of the surgical specimens at suprapubic prostatectomy has been assessed for comparative studies. The preoperative ultrasonographic assessment of the transitional zone volume correlated very well with the weight of the resected prostate (r=0.988, P<0.001, error=4.0%). So, transrectal ultrasonography with high resolution multiplannar probes (7.5MHz)could reliably assess the size of the whole prostate and that of the adenomas providing accurate preoperative evaluation.

Objective To study the apoptosis(AP) and the androgen and estrogen milieu in normal and hyperplastic prostate tissues. Methods The incidence of apoptosis was detected by means of DNA end labelling method and dihydrotestosterone (DHT) and estrogen (E 2) were radioimmunologically evaluated in 10 normal and 20 hyperplastic prostate tissues. Results No statistical difference was noted of DHT and E 2 density between the transitional and peripheral zones of normal prostate tissue.E 2 appeared to be higher in BPH but being statistically insignificant.In normal prostate tissue,the incidence of apoptosis was significantly higher in the peripheral than the transitional zone ( P <0.05) and the incidence of apoptosis(AP) in the transitional zone was significantly higher than that in BPH.No significant correlation was noted between DHT,E 2 density and the insidence of AP either in normal prostate or BPH tissues.The incidence of AP in the transitional zone,where BPH originated,was much less even in the normal prostate tissue and decreased further with aging. Conclusions The reduction of AP density might be the causative factor in the genesis of BPH and the incidense of AP density was not correlated with DHT and E 2 density denoting that the structure and morphology of peripheral and transitional zone of prostate ductal and interstitial tissues are not the same.

目的探讨雄雌激素、细胞凋亡在前列腺增长和前列腺增生(BPH)发病中的作用。方法应用DNA末端原位标记的方法对正常前列腺移行带(10例)和周围带(10例)以及BPH组织(20例)标本进行了细胞凋亡率的研究,并应用放射免疫学技术检测了相应组织的双氢睾酮(DHT)和雌二醇(E2)含量。结果正常前列腺移行带,周围带DHT和E2的差异无显著性,BPH组织中的E2含量(平均6.63ng/g蛋白)虽高于正常前列腺的移行带含量3.15ng/g蛋白,但差异无显著性(P=0.1)。正常前列腺周围带细胞凋亡率(41.2±3.9)%显著高于移行带(29.7±4.0)%,P<0.05,后者又非常显著地高于BPH组织(39±1.1)%,P<0.001。正常与增生前列腺组织内的DHT及E2含量与细胞凋亡率之间无明显相关性。正常前列腺组织中,前列腺增生的起始部位移行带的细胞凋亡率已明显下降,随着年龄的增长,凋亡率进一步下降,导致BPH。细胞凋亡率与其组织的DHT、E2无明显相关性。结论前列腺导管系统的远、近端(周围带、移行带)上皮细胞结构形态不同,其周围的间质亦有差异...
