  • Title: The mast cells of the newborn rat diaphragm and their response to histamine liberators.
    Author: Dunn CJ, Willoughby DA, Giroud JP.
    Journal: Agents Actions; 1975 Feb; 5(1):48-51. PubMed ID: 52289.
    Abstract:
    The mast cell population of rat diaphragm was estimated between birth and adulthood and found to rise with an increase in the age of rat studied. Degranulation of these cells was observed in rats from all age groups, following treatment with compound 48/80 and dextran. The association of mast cells with the blood vessel wall in adult rat diaphragm was not observed in the comparable tissues of newborn rats. These findings are discussed in relationship to the poor vascular permeability reactions exhibited by newborn and young rats.
