前列腺是男性生殖系统中最大的附属性腺,形似栗子,环绕尿道的起始部。前列腺的疾患特别是前列腺增生症和前列腺肿瘤是男性老年人的常见病。对于这些疾病的诊断,除了病史和体格检查外,常需要作前列腺液涂片检查、前列腺液脱落细胞检查和前列腺活组织检查。应用脱落细胞和活组织作形态学检查时,单从一般的组织学描述常难以确定疾病的性质和程度,需要借助定量组织学方法进行诊断。定量组织学或立体学方法自本世纪30年代开始用于生物机体许多组织的研究。但对前列腺的研究,虽有许多定量的生化指标,在形态学方面仍限于描述性质。自1975年以来,Bartsch和Bohr首次在光镜和电镜水平应用定量组织学方法研究人和动物的前列
The prostate gland is the largest accessory gland in the male reproductive system. It is shaped like a chestnut and surrounds the beginning of the urethra. Prostate diseases, especially benign prostatic hyperplasia and prostate tumors, are common diseases in older men. For the diagnosis of these diseases, in addition to medical history and physical examination, prostatic fluid smears, exfoliated prostate cells, and prostate biopsies are often required. When exfoliated cells and living tissue are used for morphological examination, it is often difficult to determine the nature and extent of the disease from general histological descriptions, and diagnosis is required by means of quantitative histological methods. Quantitative histological or stereological methods have been used in many organizations of biological organisms since the 1930s. However, although there are many quantitative biochemical indicators for the study of the prostate, the morphology is still limited to the nature of description. Since 1975, Bartsch and Bohr have applied quantitative histology at the light microscope and electron microscope for the first time to study the forefront of humans and animals.
