Idiopathic mesenteric phlebosclerosis (IMP) is a rare chronic ischemic intestinal disease, mainly in the right hemicolon, characterized by dark purple mucosa on colonoscopy and calcifications of the intestinal wall and mesenteric veins on abdominal radiography and computed tomography. In recent years, many patients who developed IMP over the long-term administration of Kampo medicines have been reported. However, the present status of IMP in patients under long-term treatment with Kampo medicines in departments specializing in Kampo therapy is unclear. We surveyed whether there were any IMP outpatients followed for 5 years or more at the Department of Oriental Traditional Medical Center, Suwa Central Hospital. We detected 2 of 257 (0.8%) patients having IMP. Both patients had undergone long-term treatment with Gardenia fruit. One of them underwent surgery due to acute abdomen, but the other was asymptomatic. The etiology and pathogenesis of IMP are still unclear. However, in patients undergoing long-term treatment with Kampo medicines, particularly containing Gardenia fruit, the possible presence of IMP should be taken into consideration, and active screening using imaging examinations is necessary even in asymptomatic patients.

Combined surgery for left Subclavian artery revascularization and CABG was performed in a 74-year-old man with diabetes mellitus. The preoperative coronary angiogram showed critical stenoses in all three major branches, and arteriography revealed obstruction at the left proximal subclavian artery. Severe atherosclerotic calcification was acknowledged circumferentially in the ascending aorta and in the aortic arch. For this patient axillo-axillary crossover bypass grafting was performed first using and expanded PTFE graft, followed subsequently by off-pump CABG using all in situ grafts (right internal thoracic artery-left anterior descending artery (RITA-LAD), left internal thoracic artery-diagonal branch (LITA-diagonal branch), gastroepiploic artery-right coronary artery (GEA-RCA)). Postoperative recovery was smooth, with disappearance of significant pressure difference between both arms (preoperatively, 46mmHg). An angiogram on the 7th postoperative day showed a widely patent axillo-axillary bypass graft along with good flow of all three coronary grafts, in which LITA was visualized well through the axillo-axillary bypass graft. For complex atherosclerotic disease of the proximal aorta and incipient portion of neck vessels associated with severe coronary sclerosis, this technique is a suitable option.

Unkei-to was used successfully to treat three patients with primary Sjögren's syndrome (pSjS). The first case was a 67-year-old woman. In April 1993, she visited Tonami General Hospital with the symptom of dry eyes. Her condition was diagnosed as pSjS from being antinuclear antibody (ANA) positive, dry eye, and decrease of saliva secretion. She used eye drops, but her dry eye did not improve, she visited our department in June 1995. Administration of Unkei-to improved her symptoms after 6 months of treatment.
The second case was a 73-year-old woman. In 1987, she was treated in our hospital for lumbago based on spondylosis. In 1991, she began to suffer from pain and swelling of the right sterno-clavicular joint (RSCJ) and was admitted. She was anti-SS-A/Ro ANA positive, schirmer's test was positive, lymphocyte infiltration was observed by lip biopsy, and thus pSjS was diagnosed. Treatment with Unkei-to resulted in the improvement of pain and swelling of RSCJ, as well as a decrease in serum C-reactive protein. But a favorable effect on dry mouth was not attained in this case.
The third case involved a 39-year-old woman who began to experience polyarthralgia and dry mouth in June 1991. She visited a neighborhood hospital and was diagnosed as pSjS from hyper γ-globulinemia, anti SS-A ANA positivity, and decrease of saliva secretion. She first visited our hospital in March 1994. We administered Keishikaryojutubu-to and improvement of polyarthralgia was observed. Subsequently, she suffered from symptoms of dry eye and dry mouth. We treated her with Unkei-to, which improved the symptoms of dryness, but not polyarthralgia in this case.
These observations suggest that Unkei-to might be a useful agent for the treatment of pSjS.

Chinese herbal medicine has historically been used for the treatment of renal disease. There are some medi cines such as rhubarb and Ompito that delay the need for dialysis. However, they only attenuate the 1/Cr-time slope but cannot reduce the Cr level. In this study, four chronic renal failure (CRF) patients who had not responded to any Western medicine were treated effectively with Astragali Radix, a traditional herbal medi cine. Serum creatinine (Cr) was clearly improved, and necessity for dialysis was delayed. In two patients, Cr was controlled stably over four years. There were no adverse effects, and no noteworthy changes in the lev els of serum phosphorus, potassium and uric acid between before and after treatment were observed. This study suggests that Astragali Radix is a useful agent in the treatment of CRF.

PURPOSE : To determine risk factors for excessive sensitivity to cold (ESC) in relation to physical features.DESIGN : A prospective cohort study carried out between July 7 and November 14,2008.PARTICIPANTS AND METHODS : Seventy female junior college students with no ESC at baseline, and a median age of 20 years, participated. We used a numerical rating scale (NRS) to classify each ESC sensation over the five days in this July-November period.To confirm physical symptoms, we used Terasawa's diagnostic scores for ki, ketsu, and sui. We defined ESC as mean NRSgeq ≥ 5.RESULTS : We documented 17 participants with ESC in November. The multivariate adjusted odds ratio for ESC was11.6 (95% CI 1.9 to 97.5) for the physical characteristic “edema”. Participants with ESC were shorter in stature than participants without ESC (-5.9cm ; 95% CI -8.6 to -3.1).CONCLUSION : Participants with edema and short stature have a high risk for ESC.

Thalamic pain is known as intractable central pain caused by thalamic bleeding and infarction. Although some physical and surgical therapies have been tried, there is no established method for its improvement. We attempted the treatment of 6 cases of thalamic pain, and 4 of them showed improvements in their symptoms. Our patients were aged 27-70 years, 4 men and 2 women. Their diagnoses were 3 cases of right thalamic bleedings, 1case of left thalamic bleeding, and 2 cases of right thalamic infarctions. The periods from onset to consulting our department were from6months to 12 years. In the 4 cases whose symptoms improved, the symptoms had almost disappeared or were decreased by at least 40%. These improved cases used formulas containing uzu or bushi. Yokukansankachimpihange was effective for two cases with mental disturbances. One case showing major improvement was treated by only the formula against oketsu. The cases whose symptoms had continued for a long time were more intractable, with the symptoms remaining to some degree in spite of their decreasing tendency. Finally, in intractable cases, their symptoms remained fixed and they had severe paralysis.

Using atomic absorption spectrophotometry, we measured serum mineral (Fe, Cu, Z n, Mg, Ca, K, Na) concentrations in blood of male athletes participating in a triathlon competition held at Nakajima, Ehime in 1989. The athletes were divided into a young group (n=9, 24.2±3.6 yr) and a middle-aged group (n=9, 49.3±4.4 yr) . Blood samples were taken on the day before the competition, at the finish, on the following day and for eight days after.
Immediately after the race, the concentrations of iron, calcium and potassium were increased significantly in sera taken from both groups, and those of copper and zinc were found to be increased only in the young group. In the middle-aged group, serum magnesium and sodium concentrations were decreased significantly. On the day after the race, most of the serum mineral concentrations had returned to values similar to those measured before the race, although the serum sodium concentration in the middle-aged group was still below the previous value, and this low level persisted for eight days after the race in both groups.
Noticeable differences between the young and middle-aged groups were that recovery of increased iron concentration in serum tended to be prolonged in the middle-aged group, and the concentrations of serum copper and zinc were higher than those in the young group throughout the measurement period, with only small changes evident before and after the race. By contrast, serum potassium concentration in the middle-aged group was lower than in the young group throughout the measurement period.

A 78-year-old woman, after mitral valve repair by placement of No. 29 Duran annuloplasty ring 6 years previously at another hospital, was admitted because of chronic heart failure and hemolytic anemia. A Doppler echocardiogram showed that mitral regurgitation was still present but not severe. The diagnosis of hemolysis was made by decreased serum haptoglobin, elevated serum lactate dehydrogenase (LDH) and progressive anemia. We estimated that the mechanism of hemolysis was related to the mitral annuloplasty with a ring and improvement of symptoms would be impossible without removal of the ring. On 25 June, 2001, the reoperation was performed through a median sternotomy, but adhesion was so severe that a standard left atriotomy was impossible. Therefore, the right thoracic cavity was opened through a mediastinal pleurotomy and a transseptal approach was taken through right atriotomy. The annuloplasty ring was partially detached from the mitral valve ring, and that part was non-endothelialized. We concluded that an eccentric regurgitant blood stream directed to the non-endothelialized portion of the annuloplasty ring appeared responsible for the hemolysis. The ring was removed and mitral valve replacement was performed with a 25mm Carpentier Edwards bioprosthesis. The removal of the source of hemolysis and the mitral valve replacement allowed prompt recovery from severe hemolysis. Decreased serum haptoglobin, elevated LDH and progressive anemia recovered postoperatively. The reoperation used was safe and effective in relieving hemolysis. The scanty literature concerned was reviewed.

We used near-infrared spectroscopy (NIRS) to study noninvasively the effects of aging on changes in muscle oxygenation during steady bicycle exercise. For the study, 6 healthy young males and 13 healthy elderly male volunteers were recruited. To evaluate the physical fitness level and to determine exercise intensity, the ventilatory threshold (VT) was first measured. As a result, elderly subjects were divided into two groups according to O2 uptake at VT (Elderly-H ; 936.0±26.4, Elderly-L ; 695.3±29.9, Young ; 790.0±51.19 ml) . Secondly we measured muscle oxygenation by NIRS at rest and during exercise at relative work intensities of VT ; 20%, 40%, 60%, 80% and 100%. In all cases muscle oxygenation at rest and during exercise was expressed as a relative value from 100% oxygenation (oxygen capacity) established by thigh occlusion (ischemia) . All subjects showed progressive deoxygenation with increasing intensity. There were no differences between the three groups in muscle oxygenation during exercise at relative work intensity of VT. These data suggest that aging and physical fitness level have no effect on muscle oxygenation below relative work intensity of VT.
