Summary UFT, a combination of the masked compound of 5-fluorouracil (FT-207) and uracil, was given to head and neck cancer patients for 1 week preoperatively and for 8 weeks postoperatively. Drug concentrations were examined in the surgically removed tissues. The concentrations of FT-207, 5-fluorouracil, and uracil were higher in tumor tissues than in normal tissues. The lymphocyte subpopulations were assessed by cytofluorometry with monoclonal antibodies. There was no evidence that adjuvant chemotherapy with UFT specifically suppresses immunocompetent cells. We therefore conclude that further clinical evaluation of adjuvant chemotherapy with UFT would be worthwhile. 相似文献

Delayed-type hypersensitivity (DTH) was depressed in mice that had been treated with monosodium glutamate (MSG) in their suckling period. Analysis of the DTH depression by use of the macrophage migration inhibition assay showed dysfunction of DTH effector T cells. The neuronal loss of nuclei in the hypothalamus, which elaborates the corticotropin-releasing factor and the hypersecretion of adrenocorticotrophic hormone, was observed in the MSG-treated mice. Therefore, DTH response may be modulated by the neuroendocrine system. 相似文献

Based on the inverse dynamics theory, a previous paper reconstructed simple-spike (SS) firing rates of Purkinje cells in the cat's flocculus middle-zone by a linear-weighted summation of eye acceleration, velocity, and position during optokinetic response (OKR). The present study investigated the SS rates during combined optokinetic and vestibular stimuli of the cells recorded in the previous paper. During the sinusoidal vestibuloocular reflex (VOR) in the light (VORL) and in the dark (VORD) the firing modulation was small. During VOR suppression (VORS) by head and visual-pattern rotation in the same direction, the modulation was deep, with the peak coinciding roughly with peak ipsiversive head velocity. During VOR enhancement (VORE), the modulation was deep, with the peak coinciding roughly with peak contraversive head velocity. If we interpret these data in relation to eye and head movements, the cells in the cat were comparable to the horizontal-gaze-velocity Purkinje cells in the monkey that encode a linear summation of eye and head velocity signals. Alternatively, if we interpret the data on the basis of the inverse dynamics theory, the SS rates during VORL, VORS, and VORE were well-fitted by the OKR components of the movements (subtraction of VORD from VORL, VORS, and VORE eye movements, respectively), but not by the whole movements, using the coefficients calculated during OKR. It is concluded that the data are interpretable by both theories when the VOR gain (eye movement/head movement) is close to 1 and the firing is dominated by eye velocity information. 相似文献

ObjectiveAlthough both sarcopenia and systemic inflammation affect the outcomes of head and neck cancer (HNC) patients, the association between sarcopenia and systemic inflammation and the combined prognostic effect of these factors in HNC patients remain unknown. This study aimed to evaluate the effect of sarcopenia with systemic inflammation on survival and disease control in HNC patients.MethodsWe retrospectively reviewed medical records of HNC patients treated between 2009 and 2016. The skeletal muscle area was measured using a single computed tomography image slice at the level of the third cervical vertebra. A prognostic score (SPLR) was developed based on sarcopenia and the platelet-lymphocyte ratio (PLR), and its prognostic value was evaluated.ResultsOverall, 164 patients were enrolled. In the multivariate analysis, sarcopenia was significantly associated with poor overall survival (OS) (p < 0.01). However, neither sarcopenia nor a high PLR was an independent prognostic factor for disease-free survival (DFS) or locoregional recurrence-free survival (LRFS). A high PLR was an independent predictor for sarcopenia (p < 0.01). A high SPLR was associated with older age, lower serum hemoglobin, and lower body mass index (all p < 0.05). Multivariate analysis revealed that SPLR was a significant independent predictor of OS, DFS, and LRFS (all p < 0.05).ConclusionsSystemic inflammation is significantly associated with sarcopenia. The survival and oncological effects of sarcopenia were enhanced when PLR was high. Thus, the combination of these two parameters may be useful for identifying HNC patients at a risk of poor survival outcomes. 相似文献

PURPOSE: In patients with chronic genotype 1b hepatitis C and a high viral load, the viral load was reduced by double filtration plasmapheresis (DFPP), followed by combined interferon and ribavirin therapy. The safety and virological effects of this treatment method were preliminarily investigated. METHODS: In nine patients with chronic hepatitis C, DFPP was performed three times on days 1, 2, and 4, and the administration of interferon and ribavirin was initiated immediately after DFPP on day 1. RESULT: The HCV RNA was undetectable in all patients after the plasma was passed through a plasma fractionator (second filter) in the DFPP circuit. After 2 weeks, the HCV RNA tended to decrease in the DFPP group more than in the control group (-2.45+/-1.12 versus -1.57+/-0.95, P=0.073). However, this decrease was not attributable to a sustained virological response (SVR) (22.2% versus 18.2%, P=0.822). Most of the adverse events were caused by the interferon and ribavirin combination therapy. CONCLUSION: DFPP can be safely performed concomitantly with interferon and ribavirin combination therapy in chronic hepatitis C patients. The combination may contribute to an early virological response. The effect of DFPP on the SVR and its significance remain to be clarified. 相似文献

It is now clear that oxidative stresses caused by reactive oxygen species, free radicals originating in them, and lipid peroxides can be factors to cause over 90% of lifestyle-related diseases including cancer, heart diseases, cerebrovascular diseases, arteriosclerosis, hypertension, and diabetes mellitus. In the present study, health conditions, nutrition intake, bodily activities, smoking/non-smoking, and sleep hours among other factors were surveyed with youths around twenty years old of age as subjects, and those results and the results of measurement of speed for the generation of 8-OHdG (8-Hydroxy-2'-Deoxyguanosine) as oxidative stress biomarker were compared for consideration. As a result, there were correlations detected as to exercise habits, cholesterol values, and smoking habits. It was also clarified that oxidative stresses decrease by continuing taking constant aerobic exercises or by quitting smoking or reducing the numbers of cigarettes to smoke. Thereby, it was suggested that the measurement of speed for the generation of 8-OHdG can provide an indicator that is useful as an integrated evaluation to improve lifestyle habits that are to be understood to induce lifestyle-related diseases. 相似文献

Background
Recently, with rapid changes in the Japanese lifestyle, the clinical condition of patients with multiple chemical sensitivity (MCS) may also have undergone change. Thus, we conducted a new survey for subjective symptoms, ongoing chemical exposures, the prevalence of allergic diseases, and presumed onset/trigger factors in patients with MCS and compared results with those of an old survey from ten years ago.Methods
The new survey was conducted from 2012 to 2015 and the old survey was independently conducted from 1999 to 2003, meaning it was not a follow-up study. Patients were initially diagnosed by physicians at five medical institutions with MCS specialty outpatient services, with 111 and 103 patients participating in the new and old surveys, respectively. The controls were a general population living in Japan, with 1313 and 2382 participants in the new and old surveys, respectively. Subjective symptoms and ongoing chemical exposure were evaluated using a quick environmental exposure sensitivity inventory. Additionally, from clinical findings recorded by an attending physician, the prevalence of allergic diseases and presumed onset/trigger factors were evaluated. Differences between new and old surveys were analyzed using logistic regression analyses and significance tests.Results
Compared with ten years ago: (1) Regarding factors affecting patients with ongoing chemical exposures, the proportion of patients affected decreased significantly for two items only (insecticides and second-hand smoke). The proportion of controls showing ongoing exposure to 8 out of 10 items changed significantly. (2) In patients, scores for chemical intolerances, other intolerances, and life impacts increased significantly. (3) In terms of the prevalence of allergic diseases among patients with MCS, bronchial asthma (adjusted odds ratio [AOR]: 5.19), atopic dermatitis (AOR: 3.77), allergic rhinitis (AOR: 5.34), and food allergies (AOR: 2.63) increased significantly, while hay fever (AOR: 0.38) and drug allergies (AOR: 0.40) decreased significantly. (4) With regard to construction and renovation, which was the presumed predominant onset/trigger factor for MCS 10 years ago, this decreased from 68.9% to 35.1%; in contrast, electromagnetic fields (0.0%–26.1%), perfume (0.0%–20.7%), and medical treatment (1.9%–7.2%) increased significantly, confirming the diversification of onset/trigger factors.Conclusion
Compared to ten years ago, for patients with MCS, an increase in avoidance behavior toward chemical substance exposures, which were presumed to be aggravating factors for symptoms, was confirmed. It has been suggested that the ongoing chemical exposure of the general population in Japan has largely changed. In addition, for patients with MCS, chemical intolerances and life impacts have become severe, the prevalence of the main allergic diseases has increased, and onset/trigger factors have become diversified. 相似文献9.

ObjectivesMalnutrition and inflammation are common in patients with head and neck cancer and are closely associated with prognosis. Although several parameters for evaluating nutritional/inflammatory status have been assessed in relation to the prognosis of patients with head and neck cancer, previous studies primarily included patients with advanced-stage disease. To date, there is no consensus regarding the most reliable parameter for predicting the prognosis of early and advanced-stage head and neck cancer. This study sought to evaluate nutritional/inflammatory prognostic factors before treatment in patients with early and advanced-stage head and neck cancer.MethodsWe retrospectively reviewed medical records of patients treated between 2008 and 2015 at our institution in order to evaluate the effects of nutritional/inflammatory parameters, including C-reactive protein/albumin ratio, modified Glasgow prognostic score, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, and Geriatric Nutritional Risk Index, on overall survival. Effects of potential risk factors on overall survival were analyzed by computing Kaplan-Meier estimates; curves were compared using the log-rank test.ResultsA total of 164 patients were enrolled. C-reactive protein/albumin ratio, modified Glasgow prognostic score, platelet/lymphocyte ratio, and Geriatric Nutritional Risk Index were found to be statistically significantly correlated with overall survival. Only the Geriatric Nutritional Risk Index remained statistically significant in the multivariate analysis. The three-year survival rates according to the four-group Geriatric Nutritional Risk Index scores for normal, low, moderate, and high risk were 95.5%, 84.3%, 53.8%, and 23.4%, respectively.ConclusionThe Geriatric Nutritional Risk Index is therefore a useful prognostic factor for patients with early and advanced-stage head and neck cancer. 相似文献
