As previously reported (1, 2) phosphorylcholine (PC) is a specific substrate for prostatatic acid phosphatase (PAP) as opposed to other acid phosphatases, e.g., lysosomal acid phosphatase. The specificity of PC for PAP is due to the pentavalent nitrogen in PC, a feature that renders PC resistant to hydrolysis by all other acid phosphatases. Detailed comparative cytochemical results in rat tissues are in press. This report deals with ultracytochemical results applying the method to normal and pathological human prostate gland.Fresh human prostate was obtained from 7 patients having transurethral resections or radical prostatectomies. The tissue was fixed in 3% glutaraldehyde- 0.1 M cacodylate buffer (pH 7.4) for 15 min, sectioned at 50 μm on a Sorvall TC-2 tissue sectioner, refixed for a total of 2 hr, and rinsed overnight in 0.1 M cacodylate buffer (pH 7.4)-7.5% sucrose.

Pathological changes in the prostate gland occur commonly with advancing age including inflammation, atrophy, hyperplasia and carcinoma and a change in volume is also evident. Estimation of volume of prostate may be useful in a variety of clinical settings. A cross-sectional descriptive study was designed to see the changes in volume of the prostate with advancing age and done in the Department of Anatomy, Dhaka Medical College, Dhaka from August 2006 to June 2007. The study was performed on 70 post-mortem human prostates collected from the unclaimed dead bodies that were under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age groups; group A (10-20 years), group B (21-40 years) and group C (41-70 years). Volume of the sample was measured by using the ellipsoid formula. The mean ± SD volume of prostate was 7.68 ± 3.64 cm3 in group A, 10.61 ± 3.99 cm3 in group B and 15.40 ± 6.31 cm3 in group C. Mean difference in volume between group A and group C, group B and group C were statistically significant (p<0.001). Statistically significant positive correlation was found between age and volume of prostate (r = + 0.579, p < 0.001). Key Words: Prostate; volume; Bangladeshi. DOI: 10.3329/imcj.v4i2.6501Ibrahim Med.

Несмотря на достигнутые успехи в диагностике и лечении, на сегодняшний день проблема хронического простатита у пациентов с доброкачественной гиперплазией простаты продолжает оставаться актуальной. Тем временем, выздоровление или же стойкая ремиссия хронического простатита наступает только у 30-35% больных, которые получают традиционное лечение. В патогенезе хронического простатита важное место занимают мембранопатологические процессы, которые обусловлены активацией перекисного окисления липидов и нарушением состояния антиоксидантной системы защиты. У больных с хроническим простатитом и доброкачественной гиперплазией простаты наблюдается существенное усиление процессов липопероксидации на фоне сниженной функциональной способности антиоксидантных систем защиты организма. Поэтому равновесие в оксидантно-антиоксидантной системе является важным звеном в поддержании гомеостаза и, в частности, при патологии предстательной железы, предопределяет включение в комплексное лечение средств антиоксидантного действия. Перспективным можно считать применение препаратов с высоким содержанием биофлавоноидов и антиоксидантных витаминов. Включение в комплексное лечение таких пациентов препарата Кверцетина приводит к сокращению сроков нормализации клинико-лабораторных проявлений заболевания благодаря восстановлению равновесия между перекисным окислением липидов и состоянием антиоксидантной системы защиты Despite the successes achieved in the diagnosis and treatment, to date, the problem of chronic progression in patients with benign hyperplasia of the growth continues to remain relevant. Meanwhile, recovery or persistent remission of chronic prostatitis occurs only in 30-35% of patients who receive traditional treatment. In the pathogenesis of chronic prostatitis, membrane-pathological processes take an important place, which are caused by the activation of lipid peroxidation and impaired state of the antioxidant defense system. In patients with chronic prostate and benign hyperplasia, a significant increase in lipoperoxidation processes is observed against the background of a reduced functional ability of antioxidant defense systems. Therefore, the equilibrium in the oxidant-antioxidant system is an important link in the maintenance of homeostasis and, in particular, with the pathology of the prostate gland, allows the inclusion of antioxidant drugs in the complex treatment. The use of drugs with a high content of bioflavonoids and antioxidant vitamins can be considered promising. The inclusion of such patients in the complex treatment of the drug Quercetin leads to a reduction in the normalization period of the clinical and laboratory manifestations of the disease due to the restoration of the equilibrium between the peroxidation of the lipid peroxidation system and the state of lipid peroxidation
