Ibusuki hot spring sand bath (SB) (Sunamushi) has traditionally been used for the relief of musculoskeletal pain. It is specified by piling up heavy (40-60 kg) and hot (50°C) sands on the lied body heated by the hot spring water gushed at the seashore of Ibusuki. In this study, remarkable circulatory activation and metabolic improvements probably due to thermal vasodilation and higher hydrostatic pressure is examined. Subjects: The subjects examined were 20 healthy males (34.3±10.5 yrs) who accepted informed consents. Methods: The subjects were thin bathrobe and kept rest for 30 min in the supine position. BP, HR and sublingual temperature measurements and venous blood sampling from the indwelling catheter was done. Blood counts, blood gas pressure and plasma chemistry were examined. Then sand bath carried out for 10 min and 30 min rest under keeping sufficient warmth by blankets. Results: Systolic blood pressure was significantly increased though diastolic blood pressure was significantly reduced. HR and sublingual temperature were significantly increased by +22 bpm and +1.1°C, respectively, just after 10 min SB. Venous blood pO2 and pH were significantly increased by +18.3 mm Torr and +0.03pH, and pCO2 was significantly reduced by -5.8 mm Torr. Lactate and pyruvate were significantly reduced after 10 min and 30 min after sand bath suggesting the improved peripheral oxidative metabolism. Conclusion: Increase in blood pressure and heart rate indicating cardiac acceleration was considered to be induced by hydrostatic pressure with heavy sands and thermal vasodilation. Improved peripheral circulation and oxidative metabolism were also suggested by increased pO2, decreased pCO2 and decreased lactate and pyruvate level. Sufficient O2 supply and removal of wasted substances due to activated circulation was considered to be the basic mechanism of the effects of sand bath.

  Ibusuki hotspring sand bath (SB)(Sunamushi) is a special thermal therapy using heated sands by natural hotspring gushed at the seashore of Ibusuki city. Heated heavy sands (50°C, 40-60kg) was piled on the lied body. It has traditionally been used here for 250 years to relieve muculoskeletal and neuralgic pain, and still accepts 260 thousands visitors a year. In the present study, cardiovascular and metabolic effects by SB was studied from the viewpoint of accelerated circulation. Subjects and Methods: General physical parameters (BP, HR, sublingual temperature) and plasma chemistry were examined in 20 healthy males(36 ± 10yrs). The subjects wore thin bathrobe and a venous catheter for blood sampling were set in the forearm. They kept rest in the supine position for 30min and subjected 10min SB at the municipal SB institute with hotspring piping under the sands. In another 28 healthy subjects (44.3 ± 2.4yrs), cardiac outputs and plasma catecholamines (CA) and renin activity (PRA) were measured. In 6 subjects intracardiac study by Swan-Ganz catheterization were performed. Results: Diastolic pressure were significantly decreased by 6mmHg, and heart rate and sublingual temperature were significantly increased by +20bpm and +1.1°C, respectively, after 10min SB. Venous blood pO2 and pH was significantly increased by 20mm Torr and 0.03pH, and pCO2 was significantly reduced by 5mm Torr. Lactate, pyruvate and L/P ratio were significantly reduced suggesting improved oxidative metabolism of peripheral tissues. Plasma CAs and PRA were elevated after SB. All of these results gradually returned to the resting level after 30min. Cardiac output (CO) measured by dye dilution or thermo-dilution method was significantly increased from 5.6l/min to 10.5 l/min after 10min SB, and reduced to 8.1 l/min by removing piled heavy sands. Calculated total peripheral resistance (TPR) was significantly decreaased suggesting thermal vasodilation. Although mean right atrial pressure and pulmonary arterial pressure were increased during SB, they were immediately decreased by removing piled sands. Discussion: All of these results indicate that the basic effects of SB are derived from strong hydrostatic pressure of piled heavy sands and thermal vasodilation. Increased CO due to accelerated venous return and reduced afterload (TPR) will induce sufficient oxygen supply and increased discharge of wasted matters from peripheral tissues. These data seem to be compatible with the clinical effects of SB to relieve musculoskeletal pain and fatigue. Conclusion: Significant clinical effects is induced by increased CO due to the increased hydrostatic pressure of piled sands and thermal vasodilation.

We report an extremely rare case of primary squamous cell carcinoma of the stomach. A 69-year-old man was admitted to our hospital with a 2-month history of dysphagia and tarry stools. Endoscopic examination revealed a cauliflower-shaped protruding mass along the lesser curvature of the gastric cardia. Biopsy of the lesion revealed squamous cell carcinoma of the stomach. Computed tomography revealed a thickened stomach wall and a mass protruding into the gastric lumen. Total gastrectomy with splenectomy, distal pancreatectomy, and Roux-en-Y reconstruction was performed, together with a lower thoracic esophagectomy via a left thoracotomy. Histopathological examination of the specimen revealed well-differentiated squamous cell carcinoma of the stomach. Postoperative follow-up was uneventful for the first 18 months. However, multiple liver metastases and para-aortic lymph node metastasis developed subsequently. Despite systemic combination chemotherapy, the patient died because of progression of the recurrent tumors. Here, we review the characteristics of 56 cases of gastric squamous cell carcinoma reported in Japan.
