background: flat urothelial lesions comprise a spectrum of morphologic changes ranging from reactive atypia to carcinoma in situ (cis). urothelial dysplasia and cis are associated with the recurrence and progression of urothelial carcinoma. distinguishing cis and dysplasia from reactive atypia based on histolopathogical features alone is often difficult. using different immunohistochemical mark...

OBJECTIVE To determine whether the humoral anti-chlamydia antibody response might be related to the ineffective bacterial elimination seen in patients with Chlamydia trachomatis reactive arthritis, particularly in men, who have a higher prevalence of the disease than women. METHODS The number and specificity of the antibody responses to 27 different C trachomatis antigens were determined by w...

Monoclonal antibodies were produced against MM46, an MM antigen-positive, ascitic mouse mammary tumor of C3H/He mice, and 14 clones were found to produce antibodies reactive with MM46, but not with an MM antigen-negative MM48 tumor. Among these 14 antibodies, 10 reacted also with lymph node cells of C3H.B6-Ly-6b, Ly-6.2 congenic mice. The antigen defined by the 10 antibodies was provisionally d...

Commensal bacteria in the intestine play an important role in the development of immune response. These bacteria interact with cells of the gut-associated lymphoid tissues (GALT). Among cells of the GALT, B-1 cells are of note. These cells are involved in the production of natural antibodies. In the present study, we determined whether manipulation of the intestinal microbiota by administration...

Background: Inflammation and infectious agents such as Chlamydia pneumoniae have been associated with cardiovascular disease. Objective: To evaluate the serum high sensitivity C - reactive protein (hs-CRP) and antibodies against Chlamydia pneumoniae and Chlamydial heat shock protein-60 (Cp-HSP60) in patients with ischemic heart disease (IHD). Methods: 62 patients with IHD having either acute my...

An inhibition enzyme immunoassay was developed for quantitation of (1-->3)-beta-D-glucans in the indoor environment. Immunospecific rabbit antibodies were produced by immunization with bovine serum albuminconjugated laminarin.The laminarin calibration curve ranged from 40 to 3000 ng/ml.Another (1-->3)-beta-D-glucan (curdlan) showed a similar inhibition curve, but was less reactive on a weight b...
