Reduced gastrin secretion reduces acid secretion. Effector cells undergo active cytokine secretion and other effector activities. It also stimulates glucagon secretion and fat accumulation. Inhibition of gastrin and gastric acid secretion is lifted. They modulate bile secretion, exocrine pancreas secretion, and satiety. Blood levels of hormones reflect a balance between secretion and degradation/excretion. A medical drug for inhibiting luteinizing hormone secretion is Butinazocine. Ghrelin has inhibitory effects on gonadotropin-releasing hormone (GnRH) secretion. The pancreas is the organ responsible for the secretion of the hormones insulin and glucagon. Pathological conditions are characterized by inadequate secretion of cytokines. Circadian rhythm exerts some influence on the nighttime secretion of growth hormone. Pantoprazole is a proton pump inhibitor that decreases gastric acid secretion. Secretin release is inhibited by H antagonists, which reduce gastric acid secretion. The inhibition is accomplished by preventing the secretion of the neurotransmitter norepinephrine. Macrophages can be stimulated by T cell secretion of interferon gamma.
