Crohn's disease. Light micrograph of a section through the intestine of a patient with Crohn's disease,showing ulcers (purple) and granulomas (bottom right). Granulomas are ball-like collections of immune cells that form when the immune system attempts to wall off substances that it perceives as foreign but is unable to eliminate. Crohn's is a chronic inflammatory disorder of the intestines that causes ulceration and thickening of the lining. The cause of the disease is not clear,although it may be due to either an overactive or underactive immune system. There is no cure,although anti-inflammatory drugs and surgical removal of badly affected parts of the gut are often used. Magnification: x150 when printed at 10 centimetres tall. Human tissue | |
