Background and Objective: Prostate cancer is a prevalent disease around the world. The prostatic specific Antigen (PSA) test has recently proved itself as a useful method for the diagnosis and examination of patients with prostatic cancer. The objective of this study was to compare the stability of free PSA and total PSA in different storage settings. Materials and Method...

Cystic echinococcosis (CE) is an infection caused by the larval stage of Echinococcus granulosus. This is widely distributed through Iran, where a variety of animals act as intermediate host. The immunogenic antigens (Ag) of different compartments of the hydatid cyst have been already determined. One of these compartments is the laminated layer (LL). We have extracted a protein with the MW of 2...

background: the aim of this study was to evaluate the possible use of biomphalaria alexandrina snail antigens in diagnosis of schistosomiasis mansoni using enzyme linked immunolectrotransfere blot (eitb). methods: s. mansoni adult worm crude antigens (awa), feet and visceral humps of b. alexandrina and bulinus truncatus were used. hyperimmune mice sera (his) versus each antigen were prepared fo...

Processed antigen reacts selectively with lymphocytes bearing .appropriate surface immunoglobulin molecules resulting in the clonal proliferation of these cells, produc­ing circulating immunoglobulin (humoral immunity) or non-circulating immunoglobulins (cellular immunity).  High levels of circulating immunoglobulins (lgM & lgG) occur in protozoa and helminths infections. Reaginic antibodies a...

introduction: prostatic specific antigen (psa) is an important tumor marker of prostatic cancer and antigenic determinant of prostatic tissue. however, recently, results of several  researches have proposed existence of psa in non- prostatic tumors, extracts . in this study, our goal was to find that if patients with non-prostatic cancers synthesize psa. materials & methods : the sample was sel...
