Filtration: A slow sand filter, pressurized rapid sand filter, or pre-coat filter is the next step in treatment to filter out as many of the blue-green algae cells as possible before the water enters the disinfection system. ï Pressured rapid sand filters are the most common filters used for drinking water ponds.
Reactive urothelial cells and severe, mostly chronic inflammation. -- Urothelial cells, a type of epithelial cell found only in the urinary tract, line the urinary tract and they become reactive (changed) when injured by inflammation.
Figure 2.19. Reactive Urothelial Cellsâbladder washing: Degenerated slightly atypical urothelial cells are seen. The cells exhibit only mildly increased nuclear to cytoplasmic ratios and many of the cells contain abundant cytoplasm. Note that the nuclear size is smaller than the size of intermediate squamous cells.
