41. Pepsin may also cause mucosal damage during weakly acidic or non-acid gastric reflux. 42. MEN IIA also presents with hyperparathyroidism, while MEN IIB also presents with mucosal neuroma. 43. This phase is associated with a fall in progestogen levels, mucosal proliferation and keratinization. 44. Diseases associated with this genus include : hemorrhagic syndromes, abortion, fatal mucosal disease. 45. It acts as an antihistaminic and sympathomimetic, reducing swelling, inflammation and mucosal secretions. 46. Stimulation of AT 2 by the selective agonist CGP 42112A increases mucosal nitric oxide production. 47. The measurement of gut mucosal carbon dioxide has been used to detect decreased blood flow. 48. Severe ulceration of the gastrointestinal mucosal surfaces occurs in less than 16 % of cases. 49. This causes blood vessels to dilate and allow for fluid buildup in the mucosal surfaces. 50. When inside the host, the parasite infects the mucosal crypts of the large intestine.
