[Effect of mineral waters with different salt composition on changes in parenchymal-stromal ratio of the laryngeal wall glands in rats].

The aim of the present investigation was to study the laryngeal glandular apparatus as influenced by the application of baths with different mineral composition. 100 mature outbred male rats aged 3-4 months with 180-200 g body mass were studied in this investigation (including 60 experimental and 40 control animals). After a 28-days-long balneologic course using mineral waters with different composition, the histological and morphometric study of laryngeal gland was performed in different parts of the organ to assess the relative contents of parenchyma and stroma.
