We visited Mongolia in the summer of 1999 and again in the summer of 2000, and investigated the traditional and natural medicines of this country. Mongolian traditional medicine is classified into seven categories, namely, massage, acupuncture, herbal medicine, dietary cures, aromatherapy, phlebotomy and sutra recitation. Herbal medicines, as well as acupuncture and massage, are the principal remedies. These remedies are based on Tibetan traditional medicine, which is derived from Indian traditional medicine. In both rural and urban areas, the Mongolian people use many herbs and herbal prescriptions to prevent and cure acute or chronic diseases. Important herbal plant sources, such as the Ephedra and Glycyrrhiza species, are abundant. Since the abandonment of socialism, traditional medicine has made a rapid comeback and is now a popular and important remedy in Mongolia.

We investigated the effects of an ethanol extract of potato peel on T helper cytokines production in cultured murine Peyer’s patch cells ex vivo. Oral administration of the 70% ethanol extract at 100 mg/kg/day significantly enhanced the production of the Th1 cytokine IL-2 in response to concanavalin A. A decrease in the production of the Th2 cytokine IL-4 and the Th17 cytokine IL-17 was observed. The production of the Treg cytokine IL-10 was not affected. These results suggest that the potato peel extract stimulates Th1 immune response.

A 84-year-old man was admitted with an abdominal tumor. Prosthetic graft replacement between the aorta and the left external iliac artery was performed 17 years previously. CT scan and angiography showed a large anastomotic pseudoaneurysms at the sites of proximal and distal anastomosis. A Y graft prosthesis replacement was performed. The size of the proximal anastomotic pseudoaneurysm was 7×6×5cm, and that of the distal anastomotic pseudoaneurysm was 15×10×10cm. They resulted from cutting at anastomosis. Large anastomotic pseudoaneurysms at both sites is rare.

A 73-year-old woman was admitted to undergo three simultaneous operations: aortic valve replacement (AVR), coronary artery bypass grafting (CABG) and abdominal aortic aneurysm repair. She had previously undergone percutaneous catheter intervention in the left coronary anterior descending artery. Computed tomography revealed an abdominal aortic aneurysm 5cm in diameter. Aortic valve stenosis (AS) was shown with a pressure gradient of 60mmHg, and 90% stenosis of the distal right coronary artery was also shown. CT scan and aortography revealed porcelain ascending aorta. The patient underwent simultaneous operations because of severe AS, coronary artery disease and abdominal aortic aneurysm. An aortic cannula was placed in a position higher in the ascending aorta with no calcification. Cardiopulmonary bypass was started using a two-staged venous cannula through the right atrium. At first, AVR was performed with cardioplegic solution and ice slush. Because it was difficult to inject the cardioplegic solution into the coronary artery selectively due to the calcified orifice of coronary artery, we closed it immediately by removing the calcified intima of the porcelain aorta after completion of AVR. The second cardioplegic solution was injected through the ascending aorta. Next, CABG to RCA was performed using the right gastroepiploic artery without anastomosis to the ascending aorta. Cardiac surgery was first performed, followed by abdominal aortic aneurysm repair after discontinuation of cardiopulmonary bypass. The patient was extubated the next day and stayed for two days in the intensive care unit. She is very well now one year after the operation.

Introduction : We examined the characteristics of paralytic scoliosis using plain radiography.Subjects and methods : We recruited fourteen patients aged ≥ 15 years old with no history of bone surgery at the time of their final observation. Participants included those who had cerebral palsy or those who had a history of encephalitis and underwent spinal frontal plain radiography in the supine position at different time points. We evaluated gross motor function, position and direction of the curve, Cobb angle, rate of variability, and degree of progression at 5-year intervals. We measured the percentage of migration using hip frontal plain radiography to assess hip dislocation.Results : The final Cobb angles were 82.0°, 118.4°, and 92.3°for the thoracic, thoracolumbar (TL), and lumbar curvatures, respectively. TL curvatures showed the greatest progression, although this was not statistically significant. The progression was greatest in the 10-15-year age group (12.5°annually). The final Cobb angles in the hip dislocation, subluxation, and no dislocation groups were 102.8°, 108.8°, and 87.5°, respectively；the difference was not statistically significant. No relationship was observed between the location or progression of curvature and the state of the hip location.Discussion : Paralytic scoliosis progressed most rapidly in 10-15-year-old patients, especially in those with TL lesions. We did not detect any relationships between hip dislocation and Cobb angle, but these parameters progressed at different rates in different patients.
