Abstract
This study investigated a case of spindle cell carcinoma (SpCC) in tongue pathological lesions. The patient experienced a local recurrence and distant metastasis after surgical intervention. Although standard chemotherapy was administered, a granulomatous mass continued to develop. This aggressive growth led to survival of the tumor. Secondary debulking surgery was performed to improve the patient's quality of life at the request of the patient. Using a tissue sample derived from the secondary debulking surgery, we performed an analysis of the tumor's cell surface antigens, differentiation potential, metastatic ability, and inhibition potential by anticancer reagents. In vitro analysis revealed that the cell population grown under adherent culture conditions expressed the mesenchymal stem cell (MSC) markers CD73, CD90, and CD105. The cell line established from this SpCC contained colony-forming unit fibroblasts (CFU-Fs) and exhibited multipotent differentiation into several mesenchymal lineages, including bone, cartilage, and fat. The SpCC cells also displayed vigorous mobilization. These characteristics suggested that they had the differentiation potential of mesenchymal cells, especially MSCs, rather than that of epithelial cells. The surgical specimen analyzed in this study resisted the molecular target reagent cetuximab, which is an epidermal growth factor receptor inhibitor. This clinical insight revealed that chemotherapy-resistant SpCC cells have different characteristics compared to most other cancer cells, which are sensitive to cetuximab. Our cell death assay revealed that SpCC cell death was induced by the anticancer drug imatinib, which is known to inhibit protein tyrosine kinase activity of ABL, platelet-derived growth factor receptor α (PDGFRα), and KIT. Here, we report recurrent SpCC with characteristics of MSCs and potential for treatment with imatinib.

Abstract
Human dental pulp stem/progenitor cells (hDPSCs) are attractive candidates for regenerative therapy because they can be easily expanded to generate colony-forming unit-fibroblasts (CFU-Fs) on plastic and the large cell numbers required for transplantation. However, isolation based on adherence to plastic inevitably changes the surface marker expression and biological properties of the cells. Consequently, little is currently known about the original phenotypes of tissue precursor cells that give rise to plastic-adherent CFU-Fs. To better understand the in vivo functions and translational therapeutic potential of hDPSCs and other stem cells, selective cell markers must be identified in the progenitor cells. Here, we identified a dental pulp tissue-specific cell population based on the expression profiles of 2 cell-surface markers LNGFR (CD271) and THY-1 (CD90). Prospectively isolated, dental pulp-derived LNGFR(Low+)THY-1(High+) cells represent a highly enriched population of clonogenic cells--notably, the isolated cells exhibited long-term proliferation and multilineage differentiation potential in vitro. The cells also expressed known mesenchymal cell markers and promoted new bone formation to heal critical-size calvarial defects in vivo. These findings suggest that LNGFR(Low+)THY-1(High+) dental pulp-derived cells provide an excellent source of material for bone regenerative strategies.

Abstract
In recent years, proactive surgical treatment has been reported to be effective for medication-related osteonecrosis of the jaw (MRONJ). However, an uncertain resection entails the risk of recurrence, whereas an extensive surgical procedure may lead to a marked reduction in quality of life as a result of reduced masticatory function and poor cosmesis. Therefore, radiological assessment can be helpful to accurately localize MRONJ before surgery. The integrated single-photon emission computed tomography and computed tomography system (SPECT/CT) allows oral and maxillofacial surgeons to identify an area of MRONJ, especially when three-dimensional (3D) SPECT and CT fusion images are offered. A patient for whom 3D SPECT and CT image fusion (as developed in the radiology department of the study institution) contributed to determining the extent of the lesion, thereby leading to a favourable patient prognosis, is reported herein. There was exact correlation between the histological and radiological results.

Abstract
AbstractHydroxyapatite (HA) has been universally used because of good biocompatibility. There are varieties of coating methods, however, they still have problems. The most significant problem is layer thickness. We introduced a new coating procedure to eliminate this difficulty.The characterization of the coating was studied by X-ray diffractometry, infrared spectroscopy, SEM and chemical analysis. Said examination indicated that the double layer consisted of carbonate HA and CaTiO3 and the thickness of the layer was 2-4 μm. The coating was performed on the inner surfaces of 50-200 μm sized pores and was also consistent in the smallest of the pores even those of 50 μm. Our results indicated that the coating layer was homogeneous and thin. In addition, both layers consisted of Ca ions. The consistency of coating into even the smallest pore size suggested that our method promises to have widespread clinical applications in artificial implants because of increased surface contact area.

Abstract
AIMS Glimepiride, a third generation sulfonylurea (SU), is known to have extrapancreatic effects, but its vascular effect is unclear. We investigated the efficacy of glimepiride in improving arterial stiffness assessed by cardio-ankle vascular index (CAVI) in type 2 diabetic patients, compared with glibenclamide, a conventional SU. METHODS Forty type 2 diabetic patients were randomly assigned to two groups. One group was administered glimepiride 1.5 mg/day, and the other group was administered glibenclamide 1.25 mg/day for 6 months. RESULTS No significant difference in hypoglycaemic effect was observed between two groups. CAVI significantly decreased only in glimepiride group (9.4 ± 1.4→8.9 ± 0.8, p < 0.05). Decrease in CAVI was greater in glimepiride group than in glibenclamide group (-0.50 ± 0.98 vs. -0.04 ± 0.57, p = 0.048). Urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) decreased in glimepiride group and increased in glibenclamide group, and the changes were significantly different between groups (-1.5 ± 3.5 vs. + 1.8 ± 3.6, p = 0.009); whereas serum lipoprotein lipase mass increased in glibenclamide group and decreased in glibenclamide group, and the changes tended to be different between groups (+ 2.1 ± 19.1 vs. -7.4 ± 19.2, p = 0.096). Change in urinary 8-OHdG was a significant independent predictor for change in CAVI in all subjects. CONCLUSIONS These results suggest that glimepiride improves CAVI compared with glibenclamide. Reduced oxidative stress and improved insulin resistance may contribute to the improvement of CAVI by glimerpiride.

Abstract
AIM We determined the characteristics of transgene expression of heart grafts following ex vivo gene transfer using an adenovirus vector. Transgene expression was assessed periodically in the same animals by a non-invasive bioimaging system. METHODS Rat heterotopic heart transplantation was performed in a syngenic combination. We infused 1 x 10(9) plaque-forming units of adenovirus vectors containing firefly luciferase gene into the heart graft via the coronary artery, with preservation at 4 degrees C and transplanted into the cervix of the recipient. Transgene expression was periodically visualized and quantified by a noninvasive bioimaging system without sacrificing experimental animals. RESULTS Transgene expression in the graft peaked at day 7 and then fell gradually. Transgene expression was also observed in the recipient liver. CONCLUSIONS We have determined the time course of transgene expression in the heart graft. This constitutes important information about ex vivo gene therapy for heart grafts.

Abstract
OBJECTIVE To report a case of decreased theophylline clearance by the addition of levofloxacin in a patient receiving theophylline and clarithromycin. CASE SUMMARY A 59-year-old Japanese man who was receiving theophylline for emphysema experienced stimulation, insomnia, and tachycardia due to theophylline toxicity after clarithromycin and levofloxacin were added to the regimen. The combination of these agents resulted in a decrease in theophylline clearance to approximately 60% of the initial value obtained while the patient was receiving theophylline alone. The adverse effects disappeared after the dosage was reduced and the theophylline serum concentration decreased; however, there was no change in theophylline clearance. After discontinuation of levofloxacin, the theophylline serum concentration decreased, and theophylline clearance returned to the initial level even though clarithromycin was continued. DISCUSSION Levofloxacin is believed not to influence the clearance of theophylline, although some new fluoroquinolones have been reported to do so. This case indicates that levofloxacin and clarithromycin inhibited theophylline metabolic pathways catalyzed by both CYP1A2 and CYP3A4 and resulted in the decrease in theophylline clearance. The clearance of theophylline, therefore, is not influenced by clarithromycin alone. CONCLUSIONS Careful monitoring is required when levofloxacin is prescribed for patients who are taking clarithromycin with theophylline.

Abstract
A questionnaire-based investigation was performed on 325 Japanese school children with Down syndrome ages 6 to 18. Data on height and body weight, eating habits, physical activity for these children were obtained through their parents. Proportion of obese children was higher among these subjects than the average for Japanese children (34.3% and 7.47% respectively, for the ages from 6 to 14). We examined characteristics of eating habits and physical activities between the obese group (obesity index greater than 20% above the average of Japanese school children) and the non-obese group. Obesity started to increase in the obese group around age 7. The obese group tended to have had a greater intake of sweets, juice and total foods in their preschool days, but unexpectedly had been physically more active in their primary school days.

Abstract
We describe here two patients with mantle cell lymphoma (MCL) who after a few years, developed to the diffuse large cell lymphoma (DLCL)( anaplastic centrocytic lymphoma) growing in a diffuse sheets without the classical MCL component. In both the initial and second biopsy specimens, in each case, tumor cells were positive for cyclin D1, sIgM, sIgD, and CD5, but were negative for CD10 and CD23. In a study of immunoglobulin heavy chain (IgH) gene rearrangement, using the polymerase chain reaction (PCR) method, the products obtained from each paired biopsy tissue sample were the same size, and in one case had an identical sequence to the non-mutated VH gene. Immunohistochemistry was used to examine the expression of p53, p27(Kip1) and cyclin E. Interestingly, there was clear overexpression of p53 protein in case 1 but not in case 2, compared with other typical MCL cases. The expression of p27(Kip1) in the second biopsies of each case was decreased compared with those in the initial biopsies. In case 2, however, p27(Kip1) was clearly expressed in the first and second biopsies, in contrast to other typical MCL cases. Thus these 2 cases demonstrate not only that the variant form of MCL may arise de novo, but also that MCL may transform to DLCL at the time of relapse. Although the mechanism of tumor progression/transformation is still poorly understood, the overexpression of p53 or p27(Kip1) may be linked to a cellular mechanism involved in the development of the variant form of MCL.

Abstract
We describe here two patients with mantle cell lymphoma (MCL) who after a few years, developed to the diffuse large cell lymphoma (DLCL) (anaplastic centrocytic lymphoma) growing in a diffuse sheets without the classical MCL component. In both the initial and second biopsy specimens, in each case, tumor cells were positive for cyclin D1, sIgM, sIgD, and CD5, but were negative for CD10 and CD23. In a study of immunoglobulin heavy chain (IgH) gene rearrangement, using the polymerase chain reaction (PCR) method, the products obtained from each paired biopsy tissue sample were the same size, and in one case had an identical sequence to the non-mutated VH gene. Immunohistochemistry was used to examine the expression of p53, p27Kip1 and cyclin E. Interestingly, there was clear overexpression of p53 protein in case 1 but not in case 2, compared with other typical MCL cases. The expression of p27Kip1 in the second biopsies of each case was decreased compared with those in the initial biopsies. In case 2, however, p27Kip1 was clearly expressed in the first and second biopsies, in contrast to other typical MCL cases. Thus these 2 cases demonstrate not only that the variant form of MCL may arise de novo, but also that MCL may transform to DLCL at the time of relapse. Although the mechanism of tumor progression/transformation is still poorly understood, the overexpression of p53 or p27Kip1 may be linked to a cellular mechanism involved in the development of the variant form of MCL.

Abstract
The cell cycle is governed by a family of cyclin-dependent kinases (Cdks). Cdk2 forms a functional complex with cyclin E and plays a pivotal role in the regulation of G1/S transition. Cdk2 activity is negatively regulated by interactions with inhibitors. p27Kip1, one of the most potent inhibitors of Cdk2, was recently identified as a powerful negative prognostic marker in non-small cell lung cancer as well as in colorectal and breast cancer. In the present study, the expression of p27 and Ki-67 antigen in nonneoplastic and cancerous lung tissues was determined by immunohistochemistry. After establishing that the antibody-measured p27 labeling index was a good reflection of the level of p27 expression measured by Western blotting, we show that p27 labeling index is decreased in cancerous lung tissues, compared with nonneoplastic lung tissues, and exhibits a significant inverse relation to the proliferation marker Ki-67 antigen, detected with monoclonal antibody MIB-1. Consistent with these data, all cancerous lung tissues showed enhanced degradation activity of p27 compared with nonneoplastic lung tissues and, in addition, increased levels of the phosphorylated form of Cdk2, as determined with Western blot analysis. The H1 histone kinase activity associated with Cdk2 was also increased in non-small cell lung cancers. Statistical analysis showed that proliferative activity as measured by MIB-1 labeling index was highly correlated with Cdk2 activity (r = 0.767, P < 0.0015). These results suggest that p27 and Cdk2 may play an important role in the proliferation of non-small cell cancer.

Abstract
Surgical management of patients with concomitant resectable lung lesions and critical cardiac disease is controversial. We report a case of concomitant pulmonary and cardiac surgery via a left thoracotomy. A 67-year-old male was admitted to our hospital complaining of recurrent bloody sputum and an abnormal shadow on chest X-ray. Chest CT and MRI showed a tumor in the left lower lobe (S10), with invasion of the diaphragm. A diagnosis of squamous cell carcinoma was obtained by transbronchial lung biopsy. The patient had a history of angina pectoris, and stress testing was positive. Coronary angiography showed 90% stenosis at segment 5, suggesting a risk of perioperative or postoperative myocardial infarction. This necessitated simultaneous surgical treatment for lung cancer and ischemic heart disease. A lobectomy of the left lower lung was performed, followed by coronary artery bypass grafting (CABG), using the great saphenous vein. The postoperative course was uneventful except for the occurrence of cholecystitis. Lung cancer and ischemic heart disease can be safely treated simultaneously via a single incision, with and benefit for selected patients.

Abstract
Pre- and post-operative exercise tests and unilateral pulmonary artery occlusion tests were performed on 15 surgical patients with pulmonary cancer. The relationship between these cardio-pulmonary parameters and exercise tolerance was studied, and pulmonary functional resectability was discussed. Pre- and post-operative anaerobic thresholds correlated with driving pressure (D.P: pulmonary artery pressure--pulmonary wedge pressure), and the pulmonary vascular-resistance index (PVRI). From the regression line and post-operative energy metabolic ratio, the standard limitation point of pulmonary resection can be estimated, (D.P = 22.6 mmHg PVRI = 621 dyne.sec.cm-5.m2). These data yielded a pulmonary pressure = 33.4 mmHg, total pulmonary vascular resistance index = 885 dyne.sec.cm-5.m2. These correlations were obtained because D.P and PVRI indicate the over all condition of the pulmonary vascular bed, gas exchange, ventilation and cardiac function. These data were in close agreement with previous results pertaining to the above indications. Unilateral pulmonary occlusion testing predicted the post-operative exercise tolerance of patients undergoing lung resection.

Abstract
A 45-year-old male was admitted with chief complaint of hemoptysis. Prior to admission, a tumor in the S3 segment of the right lung had been detected by chest radiography. Despite a detailed examination after admission, no definite diagnosis was made, and right upper lobectomy was performed. Histopathological examination of the surgically resected tissue led to the diagnosis of pulmonary actinomycosis. In Japan, 52 cases of this condition were reported between 1964 and 1991. This paper discusses the epidemiology, diagnosis and diagnostic imaging of the condition, with reference to the literature.

Abstract
The effects of birth season on the case fatality rate (CFR) of pulmonary tuberculosis were examined in case records of 9206 patients discharged during 1937-1965 from a national hospital for tuberculosis in Tokyo. The CFR was over 60% until 1945, then it decreased down to less than 9% after 1950. Male cases had little variation in their CFR by their birth season, while female cases had a significant variation and showed a significantly higher CFR than the male cases when they were born in January-June. The results suggest that the birth season had a significant influence on the prognosis of pulmonary tuberculosis.

Abstract
A successful operation for a patient of unstable angina with hypoxia is reported. A 80-year-old woman was admitted with severe chest oppression. The selective coronary angiogram revealed 3-vessel disease. Symptoms were uncontrolled by medical therapy. Aorto-coronary bypass surgery (with 3-saphenous vein grafts) was followed by excellent post-operative course. The patient has been asymptomatic for more than 1 year after operation.

Abstract
Vital records of Saybrook and Plymouth in New England from the 17th century were investigated. Among 8,562 maternities 81 twin maternities were found, the twinning rate being 0.95%. Twinning rate was low at the 1st and 2nd births as compared with the 3rd or later births, and was highest at the 7th and 8th births (1.6%). Twin maternity seemed to be a strong risk factor to terminate reproduction, particularly after 6 or more children had been delivered. The rate of mothers who had any other child ("fertile" mothers) at the 7th or later birth order was significantly lower for twin (13%) than for singleton maternities (63%). Twinning rate also varied by the size of offspring of a mother, and those mothers who had 5 or 6 children showed the highest twinning rate (1.3%). Those fertile mothers who had 7 or more children showed the lowest twinning rate (0.74%), although an exceptionally higher twinning rate was seen at their last births. Elongation of the last birth interval was observed for each group of every family size, and higher twinning rates were generally observed at their last births. Reduction in fecundity and rise in twinning rate seem to have occurred simultaneously at the last stage of the reproductive period of mothers, regardless of their family size.
