    Abstract:
    In 14 volunteers, saliva from both parotid, submandibular and sublingual glands were collected by capsules under stimulation of sialosis with citric acid or alimentary trial breakfast. It was taken immediately and on the 1st and 3rd hours of postprandial response. In saliva and the blood serum, alpha-amylases, trypsin, common protein, thyrotropin, thyroxine, triiodthyronin, luteinizing hormone, follicle-stimulating hormone, prolactin, progesterone, oestradiol and hydrocortisone were assessed by means of immuno-assay technique. All but oestradiol hormones had a lower concentration in the saliva than in the blood serum. The concentration and deficits of hormones and trypsin in saliva of submandibular and sublingual glands is higher, than in saliva of parotid glands, the latter having a higher alpha-amylolytic activity. The share of p-amylase in comparison with s-amylase in saliva of parotid glands is lesser than in saliva of submandibular and sublingual glands. In alimentary stimulation of sialosis, the saliva with higher amylolytic and tryptic activity, higher concentration of thyrotropin and thyroxine was found than under a non-alimentary stimulation. After the 1st and the 3rd hours following a trial breakfast, in response to a non-alimentary stimulation of sialosis the saliva was found to preserve properties of a postprandial saliva.
