The usefulness of pre- and post-operative adjuvant chemotherapy in colorectal cancer patients was studied by the North Kyushu Co-operative Study Group for Cancer Chemotherapy (21 participating institutions). Comparisons were made among group I given a tegafur suppository preoperatively+tegafur oral preparation postoperatively, group II given a tegafur suppository preoperatively+UFT oral preparation postoperatively and group III given a tegafur oral preparation postoperatively. No differences were seen in the incidence of postoperative complications depending on whether or not tegafur suppositories were administered preoperatively. There were also no differences in the symptom or incidence of side effects due to postoperative administration of tegafur or UFT. In a study of 5-FU concentration in the lymph nodes due to preoperative tegafur administration and recurrences, the concentration of 5-FU was significantly higher in the lymph nodes of cases without recurrences than in those with recurrences, and it was suggested that a relation exists between the concentration of agent and recurrences. The concentration of 5-FU in the lymph nodes of Dukes B patients was significantly higher in cases without recurrences than in those with recurrences. The non-recurrence rate (healthy rate) was better in the group given UFT postoperatively than in that administered tegafur postoperatively although the difference was not significant. 相似文献

Intravenous immunoglobulin (IVIg) preparations are reportedly effective in inhibiting the relapse of multiple sclerosis (MS), but few reports have investigated the effect of IVIg on dendritic cells (DCs), which are thought to be involved in such relapses. In the system that uses monokines to differentiate DCs from peripheral blood monocytes (Mo-DCs), we investigated the effect of immunoglobulin G (IgG) on these antigen-presenting cells. Using monocytes derived from healthy volunteers, IgG partially inhibited the expression of CD1a, a marker of immature DCs (imDCs), and CD40 and CD80, which are markers associated with T cell activation. In contrast, IgG enhanced the expression of CD83, a marker of mature DCs (mDCs). Furthermore, IgG markedly inhibited the expression of CD49d [very late activation antigen (VLA)-4 alpha4-integrin], the adhesion molecule required for mDCs to cross the blood-brain barrier. We obtained similar results on all the aforementioned cell surface molecules investigated in both healthy controls and MS patients. In addition, IgG treatment of cells from both healthy controls and MS patients inhibited the production of interleukin (IL)-12, a cytokine associated with mDC differentiation, but did not inhibit the production of IL-10. These results suggested the possibility that IgG treatment, apart from its known ability to regulate inflammation, may help to prevent relapses of MS by controlling DC maturation, consequently inhibiting invasion of immune cells into the central nervous system and affecting the cytokine profile. 相似文献

Background
Mycoplasma pneumoniae (MP) is the primary cause of community-acquired pneumonia. We aimed to evaluate the correlation between clinical features, with special reference to hypoxemia and the total affected area obtained using high-resolution computed tomography (HRCT).Methods
Medical records of MP pneumonia patients > 15 years of age at Kyorin University Hospital between January 2006 and November 2013 were reviewed retrospectively and compared to patients with Streptococcus pneumoniae pneumonia, diagnosed between January 2013 and September 2014.Results
We identified 65 and 32 patients with MP- and S. pneumoniae pneumonia, respectively. HRCT data were available for 42 and 32 patients with MP- and S. pneumoniae pneumonia, respectively. Data were available for all hypoxemic patients. Hypoxemia was significantly higher in patients with S. pneumoniae (14/32, p = 0.008) than those with MP (5/39). Total visual score on HRCT correlated significantly with hypoxemia in both groups, but showed significantly higher scores with MP- than with S pneumoniae pneumonia in hypoxemic patients.MP pneumonia showed significant positive correlation between the total visual score and serum inflammatory markers (C-reaction protein [r = 0.43, p = 0.025] and lactate dehydrogenase [r = 0.466, p = 0.016]). In both groups, individual scores in the middle and lower lung fields were significantly higher than in the upper field, suggesting zonal predominance.Conclusions
This study provides the first evidence that the total affected area on lung HRCT was more with MP compared to S. pneumoniae pneumonia in hypoxemic patients and positively correlated with hypoxemia and serum inflammatory markers. 相似文献84.

Size-specific dose estimate (SSDE) takes into account the patient size but remains to be fully validated for adult coronary computed tomography angiography (CCTA). We investigated the appropriateness of SSDE for accurate estimation of patient dose by comparing the SSDE and the volume CT dose index (CTDIvol) in adult CCTA. This prospective study received institutional review board approval, and informed consent was obtained from each patient. We enrolled 37 adults who underwent CCTA with a 320-row CT. High-sensitivity metal oxide semiconductor field effect transistor dosimeters were placed on the anterior chest. CTDIvol reported by the scanner based on a 32-cm phantom was recorded. We measured chest diameter to convert CTDIvol to SSDE. Using linear regression, we then correlated SSDE with the mean measured skin dose. We also performed linear regression analyses between the skin dose/CTDIvol and the body mass index (BMI), and the skin dose/SSDE and BMI. There was a strong linear correlation (r = 0.93, P < 0.001) between SSDE (mean 37 ± 22 mGy) and mean skin dose (mean 17.7 ± 10 mGy). There was a moderate negative correlation between the skin dose/CTDIvol and BMI (r = 0.45, P < 0.01). The skin dose/SSDE was not affected by BMI (r = 0.06, P > 0.76). SSDE yields a more accurate estimation of the radiation dose without estimation errors attributable to the body size of adult patients undergoing CCTA. 相似文献

BACKGROUND/AIMS: The overall outcome of T2 gallbladder carcinoma has not been favorable, although there is a modest hope for long-term survival after radical resection. The aim of this study was to examine factors influencing postoperative disease-free survival of patients with T2 gallbladder carcinoma to clarify optimal treatment. METHODOLOGY: Of 53 patients with gallbladder carcinoma who had undergone surgical resection from 1985 to 2000, 22 had T2 carcinoma histologically proved. The significance of variables for disease-free survival was examined retrospectively by the Kaplan-Meier method and the log-rank test. RESULTS: There were 16 patients with stage II (T2N0M0), 6 with stage III (T2N1M0) disease. Eleven patients were treated by extended cholecystectomy with resection of the extrahepatic bile duct, 10 patients underwent extended cholecystectomy without resection of the extrahepatic bile duct, and 1 patient underwent cholecystectomy. All patients underwent lymph node dissection in the hepatoduodenal ligament, below the pancreatic head, and along the common hepatic artery. Lymph node metastasis was present in 6 patients. Lymphatic, venous, and perineural invasions were found in 9, 4, and 4 patients, respectively. The absence of lymphatic invasion was a significant factor related to good postoperative disease-free survival (5-year disease-free survival rate, 88.9% vs. 31.3% in the presence of lymphatic invasion). Lymph node, venous, or perineural invasion, and surgical procedure were not significant factors to good postoperative disease-free survival. CONCLUSIONS: For patients with T2 gallbladder carcinoma, the presence of lymphatic invasion is an unfavorable prognostic indicator that calls for additional treatment after radical surgery. 相似文献
