Objective To study the antigen presenting function of keratinocytes to CD8 + T cells with specific TCR.Methods PAM212transfectants,which express H-2K b /ovalbumin complex,aa257-264,were used as stimulating cells,and naive or primed CD8 + T cells with ovalbumin specific TCR were used as respon-ders.3 H-thymidin uptake values were used as indicators of T cell proliferation.Results With prestimulation of IFN-?,the proliferation of primed T cells but not naive T cells could be stimulated by PAM-OK cells.Conclusion Keratinocytes have the potential to stimulate the proliferation of TCR specific CD8 + T cells,which might explain the persistence of local immune reaction in some involved skin.

Purpose : To investigate the cooling effect on muscles prior to continuous isometric muscle contraction. Furthermore, tissue compliance, pressure pain threshold, deep tissue temperature, and tissue circulation volume were measured to investigate the cooling effect on a physical reaction. Method : The biceps brachii muscle was contracted isometrically and continuously at the 90(-) degree in flexion position with 40% of maximum contraction. The task was ceased when subjects could not keep over 70 degrees of elbow flexion. An injection type cooling stimulator was used on the biceps brachii muscle as a cooling modality. Results : The continuous contraction time in the cooled group increased significantly compared with the control group. In addition, tissue compliance and pressure pain threshold showed significant differences between the two groups. Conclusion : This study suggested that the isometric continuous contraction time in cooled muscles can be extended to 40% of MVC. The inhibition of muscle metabolism, an increase in the pressure pain threshold, and tissue compliance may affect muscle endurance.

With an increasing number of patients suffering from chronic renal failure, the question of how to prolong the period before starting hemodialysis therapy has been attracting great attention. Kremezin^® and Daio-Kanzo-To, which have been reported to produce good clinical results, were administered to two patients with chronic renal failure in the preservation phase. When the treatment started, renal function tended to deteriorate, and hemodialysis had to be introduced in both patients. We investigated possible causes of this deterioration, and the effect of the combined use of Kremezin^® and Daio-kanzo-To the renal function could not be denied. This combination therapy needs to be studied very carefully.

The purpose of this study was to examine the effects of aquatic exercise training on the trunk muscles function and activities of daily living in abdominal obese women. Nineteen abdominal obese (abdominal circumference: 90 cm or more) and fifteen age-matched non-obese women were recruited as participants in this study. The aquatic exercise training (60 min/day, three days/week for 8 weeks) based on abdominal twists for activating the trunk muscle function. Physical parameters, biochemical characteristics, arteriosclerotic parameters and activities of daily living scores were assessed before and after the training period. In both groups showed abdominal circumference, percent of body fat, blood pressure and lower extremity muscle strength increased significantly after aquatic exercising training. In particular, endurance capacity of abdominal and back muscles increased significantly and activities of daily living scores were significantly improved in the obese group. Moreover, the improvement in the strength of lower extremities and improvement in the activities of daily living scores, such as climbing and descending stairs, in the obese group tended to be higher than non-obese women. Additionally, in abdominal obese group, the amount of the reduction of abdominal circumference was significantly associated with that of the increase in the strength of lower extremities. Taken together, these findings suggest the possibilities that the present aquatic exercise training based on trunk muscle exercise improving the function of trunk and lower extremity muscles with reduction in the abdominal obesity, contributing to improve activities of daily living in abdominal obese women.

The patient, a 71-year-old man, was admitted to our department with fever from unknown causes. Ultrasonic examination of the abdominal regions revealed abnormal multiple low-density echo legions (that could be) associated with splenomegaly. For diagnostic purposes, splenic puncture was performed with the aid of an ultra-sound imaging device. Pale yellow-green pus was obtained from the lesions. Based on this finding, we made a diagnosis on the case as multiple abscess of the splean. The patient underwent intensive chemotherapy. However, he dontinued to have a high fever. On the ninth day from hospitalization, splenectomy was performed. Since then, his fever has subsided. Abscess of the spleen is a rare disease. It is generally classified into two types: one is a multiple type, and the other, a solitary type. Multiple splenic abscess mostly occurs as one of the abnormal conditions during the course of a primary disease, which is often severe. Our case, however, did not exhibit any sign of a primary disease.

Gastric cancers that fulfill the Japanese criteria for curative endoscopic resection show a low risk of lymph node (LN) metastasis. Here, we report a case of LN metastasis from early gastric cancer that fulfilled the curative criteria. A 74-year-old Japanese woman was referred to our hospital for treatment of early gastric cancer identified at the site of a hyperplastic polyp that had been diagnosed 10 years prior to presentation. Contrast-enhanced computed tomography did not show any lymphadenopathy and laparoscopy-assisted distal gastrectomy was performed. Histopathological examination revealed a predominantly moderately differentiated adenocarcinoma that measured 15 mm in size and was confined to the mucosa. However, a single metastatic regional LN was observed. A few cancer cells showed positive staining for alpha-fetoprotein. It should be noted that early gastric cancer can be accompanied by LN metastasis even if it fulfills the criteria for curative endoscopic resection.

1. 5-HT inhibits spontaneous fluid secretion as well as stimulated secretion with secretin (cAMP mediated) or ACh (Ca2+ mediated) in the isolated guinea pig pancreatic ducts. 2. The inhibitory effect of 5-HT is reversible and is dependent on the concentration in the range 0.01-0.1 microM, which is much lower than those that affect intestinal motility and secretion. 3. The 5-HT3 receptor in duct cells appears to mediate the inhibitory effect of 5-HT. 4. [Ca2+]i is unlikely to mediate the inhibitory effect of 5-HT.

Several prospective studies on laparoscopy-assisted distal gastrectomy for early gastric cancer have been initiated, but no prospective study evaluating laparoscopy-assisted total gastrectomy or laparoscopy-assisted proximal gastrectomy has been completed to date. A non-randomized confirmatory trial was commenced in April 2015 to evaluate the safety of laparoscopy-assisted total gastrectomy and laparoscopy-assisted proximal gastrectomy for clinical stage I gastric cancer. A total of 245 patients will be accrued from 42 Japanese institutions over 3 years. The primary endpoint is the proportion of patients with anastomotic leakage. The secondary endpoints are overall survival, relapse-free survival, proportion of patients with completed laparoscopy-assisted total gastrectomy or laparoscopy-assisted proximal gastrectomy, proportion of patients with conversion to open surgery, adverse events, and short-term clinical outcomes. The UMIN Clinical Trials Registry number is UMIN000017155.

We report a case of Muir-Torre syndrome (MTS) with a very rare combination of cancers, involving bilateral eyelid cancers and breast cancer. A 71-year-old female with a history of breast cancer from 18 years prior presented with bilateral eyelid tumors. One of her siblings had lung cancer, and another had pancreatic cancer. She underwent excisional biopsy of the eyelid tumors and histopathology revealed sebaceous carcinoma of the right eyelid and basal cell carcinoma of the left. She was diagnosed with MTS: a skin cancer associated with visceral malignancy. Immunohistochemical tests for mutS homolog 2 showed a lack of expression in both eyelid carcinomas.

A 56- year-old woman visited our hospital complaining of right hypochondralgia. X-ray and endoscopic examinations revealed Borrmann 2 type gastric cancer in the anterior wall of an upper part of the stomach. Ultrasonography showed an echogenic mass in the suprarenal area. The mass which had septal formation within it, was about the same in density as fat on computerized tomography, and was hypovascular fed by the right inferior adrenal artery on angiography. These findings suggested that the mass might be adrenal myelolipoma. After total gastrectomy and right adrenectomy were done, histopathological study confirmed that the case is adrenal myelolipoma associated with Borrmann 2 type gastric cancer. In Japanese literature, only 54 cases of surgically resected adrenal myelolipoma have been reported, and this is the second case of adrenal myelolipoma associated with gastric cancer.
