An ultrastructural study of the biostimulative effect of He-Ne laser radiation on the early postnatal differentiation of the rat submandibular gland.
Submandibular gland of the rat during the first week of postnatal development was used for the study of the ultrastructural changes after the He-Ne laser radiation. In the experimental group we observed an increase of the dark cells with greater quantity of the granular endoplasmic reticulum and an increased number of specific secretory granules. These changes show positive biostimulative effect of He-Ne laser radiation on the morphologic differentiation of the submandibular gland of the rat in the early postnatal period.
