Bioelectorical impedance methods have been found to be a valid and reliable way of estimating per cent body fat (%BF) in adults. We applied them to healthy children and compared them with conventional anthropometry methods. One thousand two hundred and sixteen children participated in this study. Impedance and skinfold thickness were measured, and %BF was estimated using these values. Bodyweight and height were measured, and per cent obesity (%OB) and body mass index (BMI) were obtained. The values of %BF by the bioelectrical impedance method (%BFi) were 8.6 ± 4.0% in the junior male group, 14.2±2.8% in the junior female group, 7.9±4.7% in the senior male group and 16.1 ±2.9% in the senior female group. The % BFi correlated strongly with skinfold thickness, %OB and BMI. Thus %BFi correlated strongly with variables from conventional methods. It was concluded that it is a reliable way of assessing lipid storage in children. 相似文献

An 8‐year‐old boy was admitted to Ehime University Hospital, Ehime, Japan, for the further investigation of a 5‐month episode of gross hematuria accompanied by lower abdominal pain. Magnetic resonance imaging revealed a solid tumor measuring 3 cm in diameter of the bladder wall. Cystoscopy demonstrated a red, wide‐based, nodular tumor situated on the dome of the bladder. Histological examination of tissue taken at hot biopsy showed fibrolipoma. In consideration of potential malignancy, a partial cystectomy was carried out after informed consent was given. Histological examination of the resected specimen showed it to be cavernous hemangioma. 相似文献

Background. In order to evaluate the prevalence rates of Raynaud's phenomenon (RP) and specific clinical signs related to progressive systemic sclerosis (PSS) in the general population of Japan, inquiries were made concerning RP in the hands and dermatologic examinations were also conducted. Methods. One thousand and sixty-three subjects (332 men and 731 women) over 30 years of age who underwent inhabitants' health examinations in 1990 were considered for this study. Results. The prevalence of RP was 3.0% in men and 3.4% in women. In 8 men and 17 women with RP who received the blood tests, the positive rates of antinuclear antibody (ANA) were 12.5% and 35.3% in men and women, respectively. The prevalence rates of all five specific clinical signs related to PSS, sclerodactyly, pitting scars of the fingers, brown pigmentation of the body, shortened frenulum of the tongue, and flexion contracture of fingers, were under 2% in men and 3% in women. In women with RP the prevalence rates of sclerodactyly, pitting scars of the fingertips, brown pigmentation of the body, and shortened frenulum of the tongue were 16.0, 4.0, 4.0, and 16.0%, respectively. These values were significantly higher than those of persons without RP. Conclusions. Because some persons with primary RP may become typical cases of PSS within several years, a follow-up study, particulary for women who have positive titers of ANA with RP, should be carried out to find out whether the persons suffer from PSS or not. 相似文献

Human mercaptalbumin (HMA) and nonmercaptalbumin (HNA) could be separated by high-performance liquid chromatography (HPLC) at neutral pH. Using HPLC, the present authors found the nonmercapt-mercapt conversion (HNA ← HMA) during hemodialysis and the mercapt-nonmercapt conversion (HMA ← HNA) after hemodialysis in chronic renal failure, indicating HMA as the covalent carrier protein for sulfur-containing amino acids. 相似文献

Trial of duplication procedure for complete dentures by CAD/CAM 总被引:7,自引:0,他引:7
summary The purpose of this study was to duplicate the shapes of complete dentures by using a computer-aided design/manufacturing (CAD/CAM) system. The shapes of the complete dentures of an edentulous patient were measured using a non-contact type shape measurement system and morphological data at the interval of 0.25 mm were obtained in the X-axis and Y-axis directions. Measurement was performed from the occlusal surface and mucosal surface sides. Based on the three-dimensional morphological data, cutter paths for cutting were generated. For cutting, the three-step method consisting of rough cutting, finish cutting, and partial finish cutting was used and for duplicating the dentures the modelling wax was cut using a computerized numerical control (CNC) processor and ball-end mills with diameters of 6 mm and I mm. The method for the controlling of three axes (X, Y, and Z) of CNC machine was used, and cutting was performed only from two directions. Although further improvements are needed in the measurement and cutting in acute slope areas, the duplication of complete dentures appears to be possible using the CAD/CAM system. 相似文献

BACKGROUND: Intravenous sclerotherapy solutions can induce endothelial cell death. OBJECTIVE: The objective was to determine the relationship between sclerosant concentration and minimum contact time required for in endothelial cell death. METHODS: Cultured bovine aortic endothelial cells were exposed to a broad range of concentrations of two liquid sclerosants, polidocanol and sodium tetradecyl sulfate. Fluorescence microscopy was used to study cells using dyes specifically indicating changes in intracellular calcium levels, nitric oxide production, and loss of cell membrane integrity after sclerosant exposure. Fluorescence intensity measurements were used to identify the timing of cell death. RESULTS: Calcium signaling and nitric oxide pathways were activated by the administration of the sclerosants and were followed by cell death. The time to the activation and the cell death was dependent on the concentration of sclerosants. At 0.3% polidocanol or 0.1% sodium tetradecyl sulfate, cell death occurred within 15 minutes. At less than 0.003% polidocanol and at 0.005% sodium tetradecyl sulfate, cells remained alive after 60 minutes. CONCLUSION: Both sclerosants rapidly led to cell death at sufficiently high concentrations. At low sclerosant concentrations, cell viability was maintained beyond the recording time of the experiment. The timing of endothelial cell death is predictable based on sclerosant concentration during exposure. 相似文献

The surface expression of effector cell molecules on neutrophils was examined in 18 patients with myelodysplastic syndromes (MDS) and 20 healthy control subjects. The MDS patients were further classified as low clinical risk (L-MDS, n = 7) and high clinical risk (H-MDS, n = 11). The expression of Fc receptors for IgG (FcR), complement receptors (CR) and cellular adhesion molecules on neutrophils was determined by flow cytometry and monoclonal antibodies. The effect of granulocyte colony-stimulating factor (G-CSF) and tumour necrosis factor-alpha (TNF) on L-selectin shedding and CR up-regulation on neutrophils was also examined. The percentage of FcRI-positive neutrophils and CD11b/CR3 expression on neutrophils were significantly increased in the H-MDS patients when compared to the controls. In contrast, the expression of FcRII, FcRIII, L-selectin, LFA-1 and CD18 on neutrophils was significantly reduced in the H-MDS patients compared with the controls. The L-MDS neutrophils exhibited lower expressions of CR1, L-selectin, LFA-1 and CD18 than those of the controls. Neutrophils from some H-MDS patients showed impaired L-selectin shedding and CR up-regulation after stimulation with G-CSF or TNF, although these were not significantly different when assessed in the whole H-MDS group. These findings suggest that an altered surface expression of effector cell molecules and an impaired modulation of cellular adhesion molecules on neutrophils may contribute to the increased susceptibility to bacterial infections in MDS patients. 相似文献

Objective: This study examined the relationship between bothersome symptoms of nocturia and erectile function. Methods: Subjects comprised patients with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Patients were prospectively followed on treatment with the alpha‐1 blocker naftopidil for 8 weeks. Patient backgrounds and efficacy of naftopidil associated with LUTS and sexual activity were evaluated. Results: The percentage of patients who identified nocturia as the most bothersome symptom was 30.2% (n = 135), representing the highest percentage among International Prostate Symptom Score (IPSS) items. The number of patients with nocturia as the most bothersome symptom plateaued at an IPSS for nocturia of two or three points. In contrast, the number of patients with slow stream as the most bothersome symptom increased with symptom severity according to IPSS for slow stream. Logistic regression analysis on association between nocturia and erectile function confirmed that the odds ratio was 1.41 (P < 0.05). Naftopidil showed excellent efficacy related to male LUTS, but International Index of Erectile Function 5 (IIEF5) total score was almost unchanged. Among patients with nocturia improved by naftopidil, IIEF5 total score was significantly changed in the group with IPSS nocturia score ≤1 as compared to the group with IPSS nocturia score ≥2 per night (P = 0.038). Conclusion: Nocturia the most bothersome symptom correlated with aging. Nocturia could associate erectile dysfunction, and keeping the frequency of nocturia at ≤1 episode might be meaningful for maintaining quality of life in elderly men. 相似文献

summary The purpose of this study was to develop a new method of analysing the shape of the residual ridge. The line of the residual ridge crest was regarded as the reference for artificial tooth arrangement and a method of determining it was evaluated. The shape of a plaster model was measured with a contact-type shape measurement system. The measurement data in each frontal section were interpolated by cubic splines. The points corresponding to the residual ridge crest were calculated and superimposed onto the image of the plaster model on a monitor screen of an image processor. Using these points and the image of the plaster model, the line of the residual ridge crest was marked on the plaster model. It was concluded that this method could be used to determine the line of the residual ridge crest on a plaster model. 相似文献

A new method based on gastrointestinal transit kinetics has been developed for estimation of the absorption profiles of drugs administered orally as aqueous solutions. The utility of the method was evaluated in rats. The gastrointestinal transit profile for each segment was estimated by in-vivo studies using phenol red, an unabsorbable marker. The gastrointestinal transit profile of phenol red was well explained by a linear gastrointestinal transit kinetic model with eight segments. We also introduced the absorption process into the gastrointestinal transit kinetic model and the plasma profile was predicted by the convolution method. The absorbability of drugs in each segment was assessed by an in-situ absorption study. The validity of the model was evaluated for model drugs with different absorption characteristics. The plasma profiles predicted for ampicillin, theophylline and cephalexin were in good agreement with those observed. The overestimated plasma profile of propranolol suggests that the low bioavailability of propranolol is a result of first-pass metabolism by the intestine wall and the liver, because the calculated absolute absorption is almost perfect. This proposed model is also suitable for estimation of segmental absorption, which is useful for the development of drug delivery systems. We have demonstrated that the plasma profile of orally administered drugs can be predicted by use of gastrointestinal transit and segmental absorbability information and that this method is especially useful for estimating separately the effect of absolute absorption and first-pass metabolism on the bioavailability of drugs. 相似文献
