Borderline personality disorder (BPD) is a serious mental illness that can be challenging for everyone involved, including the individuals with the illness, as well their friends and family members.
Acute CCK2 receptor blockade inhibits gastrin-evoked but not histamine-induced acid secretion. Studies both in vivo/in situ and in vitro have suggested that while acetylcholine seems capable of activating parietal cells, it does not affect histamine secretion from ECL cells.astric acid secretion is under nervous and hormonal control. Gastrin, the major circulating stimulus of acid secretion, probably does not stimulate the parietal cells directly but acts to mobilize histamine from the ECL cells in the oxyntic mucosa. Histamine stimulates the parietal cells to secrete HCl.
Histamine is the primary effector substance released by the mast cell in response to an allergen. Antihistamines block H1 (histamine, type 1) receptors found on blood vessel endothelial cells and smooth muscle cells.he use of antihistamines to treat hayfever will also help to relieve asthma and reduce the severity of its symptoms. Antihistamines are available in tablet, nasal spray, cream, and eye drop form. The eye drops are useful for the red and itchy eyes often caused by airborne allergens like pollen.
