In noneviscerated rats, the influence of the conjoint administration of insulin and glucagon in the regenerative response triggered by 70 per cent hepatectomy using the incorporation of tritiated thymidine by nuclear deoxyribonucleic acid as a parameter has been demonstrated. The response was earlier and more intense in relation to animals not hormonally stimulated and stimulated only with glucagon (previously reported by us). Such a response has been comparatively greater both in the nonparenchymal cells and in the hepatocytes, especially in the latter, which are the main cause of the early peak of thymidine incorporation in the periportal zones indicating a greater regenerative activity than in the intermediate and centrolobular zones. In our opinion, this indicates the importance of certain extrahepatic humoral agents in the manifestation of the regenerative process. Therefore, the results of our study ascertain the determining role and synergistic action of the pancreatic hormones--insulin and glucagon--in hepatic regeneration.

UI MeSH Term Description Entries
D007328 Insulin A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D005260 Female Females
D005934 Glucagon A 29-amino acid pancreatic peptide derived from proglucagon which is also the precursor of intestinal GLUCAGON-LIKE PEPTIDES. Glucagon is secreted by PANCREATIC ALPHA CELLS and plays an important role in regulation of BLOOD GLUCOSE concentration, ketone metabolism, and several other biochemical and physiological processes.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
