The prevalence of allergic diseases such as asthma, allergic rhinitis and atopic dermatitis has increased all over the world during the last two decades. Dietary change is supposed to be associated with this increase. If it is the case, an appropriate intake of foods or drinks with anti-allergic functions is expected to stop the increase. Flavonoids, ubiquitously present in vegetables, fruits or teas possess anti-allergic activities. Flavonoids inhibit histamine release, synthesis of IL-4 and IL-13 and CD40 ligand expression by basophils and mast cells. Analyses of structure-activity relationships of representative flavones showed that luteolin, apigenin and fisetin were the strongest inhibitors of IL-4 production with an IC₅₀ value of 2–5 μM and determined a fundamental structure for the inhibitory activity. Quercetin and kaempferol showed a substantial activity with an IC₅₀ value of 15–18 μM. The inhibitory activity of flavonoids on IL-4 and CD40 ligand expression were thought to be mediated through their inhibitory action on activation of nuclear factor of activated T cells and AP-1. Administration of flavonoids into atopic dermatitis-prone mice prevented the onset of dermatitis and serum IgE elevation and ameliorated the severity of dermatitis even after the onset. In addition a preliminary trial of flavonoids for adult patients with atopic dermatitis showed a significant effect. Recent epidemiological studies reported that a low incidence of asthma was significantly observed by population with a high intake of flavonoids. Thus, these evidences will be helpful for the development of low molecular compounds for allergic diseases and it is expected that an appropriate daily intake of flavonoids may be an effective complementary and alternative medicine and a preventative strategy for allergic diseases.

We report the Lampshade Technique : a new technique using Carbo-Seal Valsalva (Sorin Biomedica, Saluggia, Italy) to facilitate preparation of a composite graft. A Bentall operation and an ascending aorta replacement were performed with a composite graft using a Carbo-Seal Valsalva. This new technique can be considered useful as it can reduce the time required for preparing a composite graft, and create a skirt portion for continuous suturing to prevent bleeding.

We present the case of a 68-year-old woman with abdominal aortic aneurysm (AAA) complicated by right ectopic kidney, in another term, congenital pelvic kidney. The patient underwent AAA repair and right renal artery reconstruction using renal perfusion with cold Ringer's acetate, and no deterioration of renal function was observed. 3D-CT was essential diagnostic procedure in order to identify the blood supply to the ectopic kidney for planning a careful surgical technique.

From March 1981 to March 1990, 61 patients with Stanford type B acute aortic dissection were initially treated by conservative therapy. Among these 61 patients, the dissected lumen became occluded due to thrombosis early after diagnosis in 25 patients (Group T) and remained patent in 36 patients (Group P). Twentythree patients in Group T (92%) and 22 patients in Group P (61%) were discharged without major complications related to acute aortic dissection. However, 2 patients in Group T (8%) and 14 patients in Group P (39%) required additional surgical therapy or died during hospitalization. The mean aortic diameter at the time of admission in Group T was smaller than that of Group P (38±3mm vs 43±7mm, p<0.05). During the observation period, there was a tendency for the diameter of the dissected aorta in Group T to decrease, but to increase in Group P. Long-term survival appeared to be better in Group T than in Group P, but there was no significant difference in the overall survival curve. Large aortic diameter at the time of admission and the presence of a true thoracic aortic aneurysm were major contributing factors influencing the prognosis. A long-term follow-up study showed that the dissected lumen reduced or disappeared in 14 of 23 patients in Group T (61%) but only 2 of 16 patients in Group P (12.5%). We concluded that the patients with small dissected aortas and thrombosed dissected lumens (Group T) can recuperate only with conservative therapy. However, patients with large dissected aortas and patent dissected lumen (Group P) may require surgical therapy even in Stanford type B aortic dissection.

Primary cardiac malignant tumors are relatively rare, and their prognosis is poor. We report a patient with sarcoma causing severe mitral regurgitation and stenosis due to rapid and specific infiltration into the mitral valve.

This study was performed to clarify whether local anesthesia or sympathetic ganglion block abolishes the effects of electrical acupuncture (EA) on the autonomic nervous system or not.
Twelve healthy adult volunteers and 24 patients are divided into the following three experimental groups of each 12. EA was performed to the traditional acupuncture points on the meridians (H7; SHENMEN and CX4; HSIMEN). (1) In control group, only EA was performed. (2) In stellate ganglion block (SGB) group, EA was performed after unilateral SGB. (3) In local anesthesia (LA) group, EA was performed after local anesthesia on the same acupuncture points. The measured parameters on the autonomic nervous system functions were heart rates, R-R intervals in ECG, blood pressure and deep tissue temperature.
Results are as follows; Means of heart rate decreased significantly by EA in both control and SGB groups. Systolic blood pressure, diastolic blood pressure and RR-CV showed no significant changes by EA in all groups. Deep tissue temperature of the anterior forearm ipsilateral to the stimulation side decreased significantly by EA in SGB group. Deep tissure temperature of the anterior forearm contralateral to the stimuli decreased significantly by EA in both control and SGB groups. In LA group, however, all parameters were not changed by EA.
In summary, the effects of electrical acupuncture on the autonomic nervous system were not much different between control and SGB groups. It seems that one side of stellate ganglion block dose not interfere with the effects of acupuncture. On the other hand, any changes on the autonomic nervous system by electrical acupuncture were not observed in LA group. The fact showed that local anesthesia abolishes the effects of acupuncture on site. Local anesthesia blocks peripheral nerves and nerve endings. Therefore, we conclude that the effects of acupuncture on the autonomic nervous system are transmitted through the peripheral nerves, especially through the sensory nerves.

We examined relation between mucosal findings of tongue and gastric mucosal lesion by comparison photographic findings of tongue with gastroendoscopic findings of stomach. Subjects of this study were 115 cases undergoing gastroendoscopic examination in our hospital. The state of tongue surface was evaluated by thickness and color of tongue coating and tongue fissure. Especially, the tongue area was divided into 9 sections in order to investigate distribution of coating and fissure. The cases showing thick coating at the lateral sections of tongue were significantly numerous in patients who had gastric ulcer, compared with the cases in those who had no gastric ulcer. From these results, it was suggested that inspection of tongue mucosa could become one of the useful examination of oriental medicine for gastrointestinal disease.

This study was designed to evaluate the perioperative outcome of dialysis patients undergoing cardiac surgery, who were managed with our perioperative dialysis program. Between April 1994 and August 1999, 11 patients (7 men and 4 women with a mean age of 57.3±10.3 (36-73)) with hemodialysis (HD, n=8) and peritoneal dialysis (PD, n=3) underwent cardiac surgery. The duration of dialysis was 5.6±4.3 years. Operation included mitral valve replacement (n=1) and isolated coronary artery bypass grafting (n=10). Patients with HD had single hemodialysis on the day before operation. Patients with PD were maintained on PD in the usual manner until the day before surgery. Intraoperative hemofiltration during extra-corporeal circulation and normokalemic non-depolarizing cardioplegic solution were used in all patients to avoid post-operative hyperkalemia. All HD patients had dialysis on the first post-operative day (POD 1), and then every other day. PD patients had PD soon after arriving at the ICU. Levels of serum creatinine, urea nitrogen, acid-base balance were successfully controlled within acceptable ranges. No patients required emergency HD or any post-operative managements for hyperkalemia in the ICU. Six of 8 HD patients required an increase in vasopressor because of a tendency toward hypotension and 4 of 8 patients suffered from atrial fibrillation during the initial HD on POD 1. Eight of 11 patients could be extubated on the first POD. No hospital death occurred. The use of normokalemic cardioplegic solution was useful to avoid post-operative hyperkalemia. Our perioperative dialysis programme successfully managed the perioperative clinical course of dialysed patients undergoing cardiac surgery.

The patient was a 74-year-old woman who had undergone mitral valve replacement with a mechanical valve for rheumatic mitral valve stenosis at age 60. She was scheduled for aortic valve replacement for severe aortic stenosis. However, she had significantly worsening anemia before the operation. Capsule endoscopy showed angiodysplasia with bleeding in her small intestine, which was considered the cause of the anemia. Because of progressive anemia, we tried embolization under angiography. However, there was no evidence of extravasation. Neither melena nor exacerbation of anemia was observed, and she underwent aortic valve replacement. She was discharged on postoperative day 22 without gastrointestinal bleeding. Heyde syndrome is aortic valve stenosis associated with gastrointestinal bleeding induced by von Willebrand disease and angiodysplasia in small intestine. Molecular multimeric analysis of von Willebrand factor and the existence of angiodysplasia with hemorrhage of the digestive tract are important for definitive diagnosis. Capsule endoscopy, which is a general examination, is more useful for diagnosis than molecular multimeric analysis of von Willebrand factor. Aortic valve replacement is the only therapeutic option for Heyde syndrome. It is important to decide the appropriate timing of AVR with cardiopulmonary bypass.

We report a case of type A acute aortic dissection in an elderly woman with immune thrombocytopenia (ITP) who underwent replacement of the ascending aorta and aortic arch and later required aortic root replacement for redissection of the aortic root one month after her initial surgery. She was an 86-year-old woman with severe mitral regurgitation, and surgery was contraindicated because of her age and ITP. In October 2014, the patient presented with back pain. Computed tomography confirmed the diagnosis of her condition as type A acute aortic dissection, and she was immediately transferred to our hospital. Because echocardiography showed severe aortic regurgitation, severe mitral regurgitation, and moderate tricuspid regurgitation, we performed replacement of the ascending aorta and aortic arch, mitral valve repair, and tricuspid annuloplasty. We used Bioglue to fuse the false lumen of the type A acute aortic dissection and used a Teflon felt sandwich for the proximal anastomosis technique. Respiratory support was discontinued 91 h after her first operation ; however, 30 days after surgery, she developed a to-and-fro murmur-a sign of the progression of heart failure. Echocardiography showed aggravation of aortic regurgitation, and computed tomography showed aortic root redissection ; therefore, 39 days after the initial surgery, we performed aortic root replacement. During the operation, we found the entry under the proximal anastomosis with an almost semicircle form at the right coronary cusp to the noncoronary cusp, and the dissection extended close to the right coronary artery ; thus, we performed bypass to the right coronary artery. Pathologic findings did not establish a causal association between the redissection and Bioglue, and we believed the fragility of the tissue and the selection of the surgical procedure to be the cause of redissection. The patient was transferred to another hospital when she was able to walk and eat, which was 121 days after her first operation. The patient required 50 units of platelet transfusion during her first and second operations, but her bleeding was easily controlled during surgery. She needed two procedures of pericardium drainage for pericardiac effusion and cardiac tamponade, which may relate to ITP. The diagnosis of redissection of the aortic root was made 30 days after the patient's first operation, on the basis of exacerbation of the to-and-fro murmur. Here, we emphasize the clinical importance of basic observations over time, such as auscultation, that are liable to be overlooked in the intensive care unit.
