The warming effect following serial bathing in the water containing Na2SO4·NaHCO3 was studied in rabbits by mass spectrometry. Rabbits, weighing about 2 kg, were placed in a bath containing Na2SO4·NaHCO3 (33g/201) at 36-37°C for 20 minutes every day for 3 weeks. By mass spectometry, the subcutaneous tissue perfusion rate was calculated on the basis of changes in the partial pressure of Argon injected on diffusion membrane of the sensor catheter. The mean subcutaneous pCO2 was 46.6 ± 14.6 mmHg in the Na2SO4· NaHCO3 bath group and 28.8 ± 6.7 mmHg in the control tap water group; the tissue perfusion rate in these two groups was 26.78 ± 6.45 ml/100g/min and 20.32 ± 7.15 ml/100g/min, respectively. The warming effect of Na2SO4·NaHCO3 bathing is thought to be derived from increased metabolism and micro-circulation dynamics resulting from dermal stimulation by Na2SO4·NaHCO3.
