Peptide stimulation effect on organotypic culture development of neuroendocrine tissues

Introduction. One of the actual task of modern biology and medicine. Is the creation of bioregulator preparation, which can stimulate the neuroendocrine system of organism. Purpose of study. Study of effect of polypeptide complex from brain cortex (PPCbc) and from pancreas (PPCp) of calfs on the cellular proliferation in organotypic culture of nerve and endocrine of young and old rats. Methods. The adequate method of organotypic tissue culture of tissue from young and old rats was used for quick biologically activity of peptides screening. Results. The square index (SI) of nerve and endocrine tissues explants were increased statistically reliable, as compared to the control, also in young and old rats, under the polypeptides complexes effect. Conclusion. The data obtained produce the base for working and quick testing of preparations for treatment of patients with pathology in brain cortex and endocrine tissues
