▦ Physiologic Action of Gut Hormones
Criteria
① Peptide must be related into blood during time that a biologic response in a target organ is being stimulated or inhibited
② IV infusion of pure natural peptide must reproduce the effect on target organ
③ Synthetic peptide should reproduce the effect found with natural peptide
④ Circulating concentration of peptide that cause stimulat
Histologically, the islets consist of three major and at least two minor cell types.
Beta cells, which synthesize and secrete insulin, make up about 60% of a typical islet.
Alpha cells are the source of glucagon, 30% of islet tissue.
Delta cell, which are less abundant, produce somatostatin.
F cells, which secrete pancreatic polypeptide.
Fifth cell type that secretes ghrelin.
Fifty cell typ
Exploring Dokdo: A Journey to the Untouched Island 독도 여행기 영작
As the sun peeked over the horizon, illuminating the quaint town of Pohang, an air of anticipation lingered in the crisp morning breeze. It marked the beginning of an extraordinary expedition to one of South Korea's most elusive destinations—Dokdo, the isolated islets nestled in the East Sea.
