The warming effect of natrium-hydrogen carbonate-sulfate springs was evaluated experimentally using rabbits with Na₂SO₄·NaHCO₃ by means of medical mass spectrometry.
No changes were seen on the subcutaneous tissue pO₂ and pCO₂.
Regional subcutaneous tissue perfusion volume was calculated at 22.57±2.08ml/100g/min (SD=4.45, n=20, p<0.05) with Na₂SO₄·NaHCO₃ bathings which was comparable to that of tap water bathing 20.85±3.56ml/100g/min, (SD=6.71, n=16, p<0.05).
Our preliminary data of the following study indicate that the effect of warming with Na₂SO₄·NaHCO₃ bathings is due possibly to some cellular changes in the connective tissue by mild stimulation of bathing, leading to amelioration of defense mechanism in the body; the study will be reported shortly.

Intercostal artery aneurysm is a rare disease, and is usually associated with aortic coarctation, trauma and infection. Until recently, diagnosis of the aneurysm had not been possible before rupture of aneurysm. However, recent advances in computed tomography (CT) and magnetic resonance imaging (MRI) have made it possible to diagnose this lesion. A 68-year-old man was admitted with an abnormal shadow on chest X-ray film. A chest CT scan showed an aneurysm beside the descending aorta, suggestive of intercostal artery aneurysm. Intraoperative inspection confirmed the diagnosis. The aneurysm was shown to be atherosclerotic in origin by postoperative histological examination.
