summary The effects of salivary or serum pellicle on Candida albicans growth, biofilm formation and cavitation on the soft lining materials were examined. Both saliva and serum pellicles reduced the antifungal effects of soft liners. The fungal biofilm formation on these materials varied depending upon both the materials tested and protein-coats, and the pellicles which significantly enhanced the biofilm formation. Similarly, the pellicles enhanced the firm colonization and hyphal invasion of the yeasts on the specimens, although the cavitation appeared to be regulated by the plasticizer used. These results suggest that the interactions between proteinaceous pellicle, tissue conditioners and fungi are complex. They also suggest that denture pellicles facilitate fungal plaque formation onto soft lining materials through several mechanisms such as reduction of the antifungal effects of soft liners, facilitation of biofilm formation, firm colonization and hyphal invasion. In addition, the composition of the materials is also involved in the susceptibility to the fungi. 相似文献

We present a congenital leukaemia with a mixed phenotype of megakaryoblasts and erythroblasts. A newborn male with exopthalmus and multiple skin nodules, had bone marrow blasts which expressed CD41b, CD42b, glycophorin-A and haemoglobin, but monocyte or lymphoid markers were negative. The patient achieved a complete remission with chemotherapy. Blasts cultured for a few months expressed erythroid markers but lost the megakaryocytic phenotype, although addition of phorbol ester induced the latter phenotype. Spontaneous colony formation was observed in semi-solid culture and the number of colonies was increased by erythropoietin. Detailed studies further indicated the heterogeneity of congenital leukaemia. 相似文献

Plasma macrophage colony‐stimulating factor (M‐CSF) levels were measured in 13 haematologic patients treated with autologous peripheral blood stem cell transplantation (PBSCT). Six of the patients showed an increase in M‐CSF peak levels (> 3000 pg/ml) during the conditioning and stem cell infusion period. The peak levels of M‐CSF in this phase correlated with thrombomodulin levels, indicating the endothelial origin of plasma M‐CSF. However, the M‐CSF levels were not influenced by TNFα. More patients with high M‐CSF levels (> 5000 pg/ml) suffered from organ failure than those with lower M‐CSF levels. These results suggest that high M‐CSF levels may correlate with cellular or organ damage in patients treated with PBSCT. 相似文献

A retrospective study was conducted of two groups of patients over (group 1, n= 57) and under (group 2, n= 655) the age of 70 years who underwent laparoscopic cholecystectomy (LC). The pre-operative physical status and systemic complications, operation time, postoperative complications, postoperative hospital stay and other clinical features of the two groups were compared. The incidence of pre-operative complications in group 1 was significantly higher than that in group 2 (P < 0.05). Postoperatively no severe complication was found in any patient. Group 1 showed significantly prolonged operation time and postoperative hospital stay compared with group 2 (P < 0.05). The difference between the groups in the intra-operative treatment time and postoperative treatment is attributed to the greater prevalence of common bile duct stone in group 1 as there was little difference between the groups in the postoperative recovery after exclusion of these patients. No pulmonary complications, which are associated with LC, were observed; the postprocedure pain was slight and the period of bedrest was short. If complications associated with pneumoperitoneum can be prevented, this surgery is an excellent measure to improve the quality of life of even elderly patients with cholecystolithiasis. 相似文献

Changes in work performances in obstructive sleep apnea patients after dental appliance therapy 总被引:2,自引:0,他引:2
HIDEKI ARAI HISAKAZU FURUTA KAZUTO KOSAKA REIZO KANEDA YOSHIFUMI KOSHINO JO SANO SHIGEHIRO KUMAGAI ETSUHIDE YAMAMOTO 《Psychiatry and clinical neurosciences》1998,52(2):224-225
Abstract The effects of dental appliances on work performances of obstructive sleep apnea syndrome (OSAS) is not well examined. This study evaluated the polysomnographic and psychological findings before and after therapy. Nine patients were diagnosed OSAS by nocturnal polysomnography. The psychological battery was performed from 13:00 to 14:00, which consisted of Uchida-Kraepelin psychodiagnostic test (U-K's test) and Bourdon's cancellation test (Bourdon's test). Approximately 3 months after the treatment, the examinations were performed. Apnea and desaturation index decreased significantly after the therapy. In addition, sleep architecture improved after the therapy compared with that before the therapy. Dysfunction of task performances, such as mean level of work amounts in U-K's test, mean error, mean performance time and mean deviation in Bourdon's test improved after therapy. We conclude that dental appliances therapy is effective not only to apnea but also to work performance in OSAS. 相似文献

The beat-to-beat variation of PR interval, which is thought to be a reflection of autonomic nervous system, is difficult to measure with accuracy because the variation is too subtle. However, R wave amplitude in the P wave triggered SAECG is easily attenuated in comparison to that in the R wave triggered SAECG, which might he due to PR interval fluctuation. To determine whether autonomic neuropathy could be detected by use of SAECG, two types of SAECGs triggered by P and R waves were recorded in 23 diabetics with autonomic neuropathy and 41 age matched controls. The peak voltage of filtered QRS complex was measured in the R wave and P wave triggered SAECGs. Percent attenuation of the filtered QRS voltage was calculated by dividing the difference between the voltages in the R wave and P wave triggered SAECGs by the voltage in R wave triggered SAECG. The percent attenuation of filtered QRS voltage was significantly smaller in diabetics with autonomic neuropathy than controls (4.6%± 4.9% vs 16.3%± 15.0%; P < 0.001). These results suggest that the degree of attenuation of filtered QRS voltage in the P wave triggered SAECG would be useful for the detection of autonomic neuropathy. 相似文献
