Purpose : The enlargement of a prostate afflicted with benign prostatic
hyperplsia(BPH) is known to be caused by the proliferation of prostatic cells under the
influence of androgen, growth factors and interaction among cells. However, their roles
are not yet to be clearly identified. Thus, we studied about the role of the growth
factors in development of BPH.
Materials and Methods : We randomly selected 46 patients who received transurethral
resection of prostate(TURP) due to prostatic enlargement and were confirmed as BPH
pathologically. Their prostatic sizes were measured using transurethral ultrasonography.
Paraffin embedded specimens from the TURP were stained with H&E
(hematoxylin-eosin). Point count method was applied to obtain the ratio among the sizes
of stroma, epithelium, and glandular lumen. Immunohistochemical stain was conducted on
bFGF(basic fibroblast growth factor: goat polyclonal antibody), and TGF-¥â
2(transforming growth factor-¥â2: rabbit polyclonal antibody). The intensity of
fluorescence (stroma; 0+1+,2, glandular epithelium 0,+1,+2,+3) of bFGF and TGF-¥â2 was
obseNed in 20 low power field under the light microscope, then measured to get an
average.
Results : The mean sixte of prostate was 44.2(¡¾21.0)ml and the ratio among the sizes
of stroma, glandular epithelium, and gladular lumen was 5.6:4:2.1, meaning that stroma
took up the largest part of a prostate. The degree of expression of bFGF and TGF-¥â2
was significantly different between actively proliferating group and inactively
proliferating group(when the proliferation rate was less than 3%, n=26).
Conclusions : This study showed that growth factors such as bFGF and TGF-¥â2
affected the proliferation rate, with individual differences and differences in time. We
think they play different roles in influencing the rate according to cellular components
such as stromal and glandular epithelial cells.
