Prevention of recurrent bacterial urinary tract infections by intravesical instillation of hyaluronic acid.

Objective: To evaluate the efficacy of vesical instillation of hyaluronic acid against recurrent urinary tract infections.

Methods: Twenty women with a history of recurrent urinary tract infections each received 9 intravesical instillations of hyaluronic acid over 6 months. Their status was assessed prospectively over 47.

Effects of a red clover extract (MF11RCE) on endometrium and sex hormones in postmenopausal women.

Objective: To evaluate the effects of a non-prescription red clover extract (MF11 RCE, Melbrosin International, Vienna, Austria) on selected sex hormones and endometrium in postmenopausal women.

Patients And Methods: One-hundred and nine postmenopausal women with an age > or =40 years were randomly assigned to one of two groups either two capsules of MF11RCE (80mg isoflavone) per day for a 90 day period, or placebo of equal design. After a 7 day washout period, medication was crossed-over for another 90 days.

Response to sublethal heat treatment of prostatic tumor cells and of prostatic tumor infiltrating T-cells.

Background: To investigate the possibilities offered by high intensity focused ultrasound (HIFU) in the field of tumor vaccination, we analyzed how prostatic cancer (CaP) cells react towards heat treatment and whether increased access to CaP cells by the immune system would be the result.

Methods: Heat/stress response of CaP cells in situ and of CaP cell lines was analyzed by immunohistochemistry, Western blotting, and Atlas array. A heat-induced change in immune recognition was analyzed functionally using human T-helper (Th)1 and Th2-cytokine release with tumor infiltrating T-lymphocytes (TIL) as responder and autologous CaP cells either heated or untreated as stimulator cells.

Cytokine expression pattern in benign prostatic hyperplasia infiltrating T cells and impact of lymphocytic infiltration on cytokine mRNA profile in prostatic tissue.

The aim of the study is to characterize the type of immune response in benign prostatic hyperplasia (BPH) tissue. BPH tissue-derived T cells (n = 10) were isolated, activated (PMA + ionomycin), and analyzed for intracellular reactivity with anti-IFN-gamma and IL-2, -4, -5, -6, -10, and -13, as well as TNF-alpha and -beta by four-color flow cytometry. Lymphokine release was tested using Th1/Th2 cytokine bead arrays.
