[The effect of heat stimulation and mechanical stress (massage) of salivary glands on the secretory parameters of salivary Hsp70. A pilot study].

The presence of Hsp70 in human whole saliva was demonstrated in the authors' previous study. In the recent study the authors investigated, whether repeated, short-term heat and mechanical stimulation of the salivary glands can specifically modify the salivary Hsp70 concentration in the human whole saliva. Some other basic secretory parameters, like salivary secretion rate, total protein concentration and amylase activity of the whole saliva were also measured.
