Abstract: Interstitial cystitis (IC) is a chronic bladder disease for which the exact etiology is unknown and for which there is no reliably effective treatment. However, it is known that the bladder epithelium is often abnormal in IC. We discovered that human bladder epithelial cells from both normal controls and IC patients are inhibited from proliferating by an anti-proliferative factor (APF) present in IC urine specimens. Inhibited proliferation may cause epithelial abnormalities characteristic of IC such as ulcerations and multiple tears in the bladder epithelium.
Abstract: A culturing system and method particularly useful for producing cellular products such as viral pathogens of cells. It includes a mass transfer culture segment, stacked filter plates to adjust the medium composition, and a product removal and concentration segment. The mass transfer culture segment utilizes changed directional flow of the medium to maximize cell growth and production of product. The stacked filter plates allow addition of sterile fresh medium and removal of growth inhibitory substances.

Abstract: An apparatus for cleaning a chamber is disclosed. Scraping blades are rotatably mounted within a chamber and parallel to a longitudinal axis of the chamber. The scraping blades are rotated circumferentially within the chamber, scraping the inner surface of the chamber to prevent the buildup of particulate matter. An annular gear assembly provides mounting support for the scraping blades. A pneumatically operated pushrod assembly rotates the scraping blades circumferentially within the chamber.
