 note = {P(論文), The Po_2, Pco_2, pH, and HC0^-_3 concentration and flow rates of parotid saliva were observed by tongue stimulation with 3 % tartaric acid at various intervals in a human subject after about a one hour rest. The Po_2, Pco_2, pH, and HC0^-_3 concentrations in parotid saliva were measured with a Blood Gas Analyzer System. The results are summarized as follows : 1) The mean Po_2 and Pco_2 of parotid saliva immediately before tongue stimulation were about 40 mmHg (range 33-44 mmHg) and 45 mmHg (41-48). There values were similar to those of venous blood. 2 ) Po_2 increased to about 50 mmHg (46-54) 5 to 10 sec. after stimulation, and then 3 to 8 min. later, it decreased to a minimum value of about 28mmHg (26-29) before returning to the resting level 15min. after stimulation, when the intervals between stimulations were longer than 2 min., similar changes in Po_2 were observed, whereas stimulations every 30 sec. or 1 min. had no effect on Po_2. 3 ) Pco_2 increased to about 98 mmHg (85-120) from the resting level of 45 mmHg (41-48) 5 to 10 sec. after stimulation, and returned to the resting level 1 min. after stimulation. When the intervals between stimulations were shorter than 20 min., the peak value of Pco_2 by the first stimulation was higher than those induced by the following stimulations. When the interval was 30 sec. or 1 min., only the peak after the first stimulation was observed. 4 ) The pH of parotid saliva was about 7.4 (7.35-7.5) 30 to 50 sec. after stimulation, and it decreased below 6.5 about 12 min. after stimulation. When the interval between stimulations was 5 min., the pH of the parotid saliva after stimulation was always above 6.5. When the interval between stimulations was 1 min. or 30 sec., it remained at about 7.5. 5 ) The HCO^-_3 concentration in parotid saliva depends almost exclusively on the pH when Pco_2 remained unchanged. When Pco_2 was high, however, the HCO^-_3 concentration was affected by the change in Pco_2. 6 ) There was no relationship between changes in the flow rate of parotid saliva and Po_2, Pco_2, pH, and the HCO^-_3 concentration. Particularly, when the interval between stimulations was shorter then 5 min., the changes in flow rate had no effect on Po_2, Pco2, pH, and the HCO^-_3 concentration.},
