to determine the normal ranges of serum age-related prostate-specific antigen (psa) level in men from beijing area without cancer.in this cross sectional study, form april 2010 to october 2011, 1611 healthy men undergoing a routine health check-up in our hospital and all men received three examinations including serum psa test, digital rectal ex-amination and transrectal ultrasound. men with an...

• Prostate-specific antigen (PSA) is a protein produced by cells of the prostate gland. The PSA test measures the level of PSA in the blood (see Question 1). • The U.S. Food and Drug Administration (FDA) has approved the use of the PSA test along with a digital rectal exam to help detect prostate cancer in men age 50 and older. The FDA has also approved the PSA test to monitor patients with a h...

The aim of this the study was to evaluate clinical situations by measuring concentration fructose and prostate specific antigen(PSA), as well studying causes risk factors infertiled men .

Introduction: Prostate cancer is the utmost communal type of in adult men. Assessment serum total prostate specific antigen (PSA) broadly cast-off as a screening assistance prompt diagnosis prostate. Irrespective size or patient’s age, 25% cut off value set less free PSA level percentage suggested for cases with values amid 4.1 and 10 ng/ml; This helps detecting cancers 95% prevent 20% unnecess...

prostate-specific antigen (psa) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a cm-sephadex c-50 and by gel filtration on a sephacryl s-200 column. a single 33-kda protein band appeared in sds-page. high pressure liquid chromatography (hplc) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...

background: prostate specific antigen (psa) has been used as a screening test for the early detection of prostate cancer (pc) for many years. although the introduction of psa test led to a considerable increase in reported prostate cancer cases, there is still some controversy over the sensitivity and specificity of this marker in distinguishing pc patients from those with benign prostate hyper...

Background: Immunoradiometric assay is one of the most common and precise methods for determination of prostate specific antigen (PSA) in clinical laboratories. Usual use of human serum in routine assays has many disadvantages such as easy contamination and precipitation, instability and unavailability. Thus in order to avoid these problems the artificial matrix was used which acts sim...

BACKGROUND Cytotoxic T cells (CTL) are considered one of the primary effector cell populations in antitumor immunity. Recent studies, however, have demonstrated the critical importance of helper T cells (Th), specifically interferon gamma (IFN gamma)-secreting Th1 cells, either by supporting an appropriate CTL environment or by recruiting other effector cells. We evaluated whether patients with...

Background: Benign prostatic hyperplasia (BPH) is the most common benign tumor in men. The etiology of BPH is still unresolved and multiple systems are likely to be involved. The effects of diabetes on urinary system are a risk factor for BPH. We then assessed the effects of diabetes on the parameters related to BPH, especially weight and volume. Methods: This study was conducted on patients...
