Abstract Fructosamine assay, which is used in diagnosing and monitoring diabetic patients, is compared with the hemoglobin and plasma glucose assays in children and adolescent insulin-dependent diabetes mellitus patients. We demonstrated that the gingival index scores were correlated with fructosamine values in insulin-dependent diabetes mellitus patients but not in non-diabetic controls. We also found that there was no correlation between gingivitis scores and fasting plasma glucose and HbAlc values. Periodontitis was found to be rare in diabetic children and adolescents. 相似文献
This study investigated the effect of diltiazem on the bioavailability of oral and intravenous cyclosporine (CsA) in rats. While control rats received normal saline, experimental groups received 60 or 90 mg/kg diltiazem orally for 3 days. Each group divided into 2 equal groups that received a single oral dose or i.v. injection of CsA. Pharmacokinetic parameters were analyzed by nonparametric analysis of variance. Pretreatment with 60 or 90 mg/kg diltiazem decreased the area under the blood CsA concentration-time curve (AUC) of oral CsA compared to control group (54.5% and 65.5% for AUC(0-24), 57.6% and 62.2% for AUC(0-infinity), respectively, p<0.05). Mean CsA maximum concentration (Cmax) decreased from 0.4 +/- 0.1 microg/ml to 0.1 +/- 0.0 microg/mL in rats pretreated with 90 mg/kg diltiazem (p<0.05). The absolute bioavailability after oral administration (F(p.o.)) in the 60 or 90 mg/kg diltiazem groups were lower than the control group (9.6% and 8.5% versus 22.6%). Pretreatment with 90 mg/kg but not 60 mg/kg of diltiazem increased the AUC(0-infinity), elimination half-life (t1/2) of intravenous CsA (116.0%, 219.2%, respectively, p<0.05) and decreased the intravenous CsA clearence (CL(i.v.)) (62.9%, p<0.05). Diltiazem decreased the bioavailability of oral CsA, while it increased the bioavailability of intravenous CsA. One must consider this interaction when administering oral or intravenous CsA concomitantly with diltiazem. 相似文献
IntroductionThe present study aimed to compare the torsional strength of the initial files of the Mtwo (VDW, Munich, Germany) and novel Rotate systems (VDW, Munich, Germany) with the ProGlider (Dentsply Sirona, Ballaigues, Switzerland) and R-Pilot (VDW) glide path instruments.MethodsThe Mtwo (10/.04), ProGlider (16/.02), R-Pilot (12.5/.04), and Rotate (15/.04) glide path files were compared regarding their torsional strength, which was tested using a specially designed test device (N = 20). The data obtained were statistically analyzed at 5% significance level using 1-way analysis of variance and the post hoc Tukey test. The fragment surfaces and separated instruments were examined with ×50, ×100, and ×1000 magnification under a scanning electron microscope.ResultsThe R-Pilot group showed the highest torsional strength value among all groups (P < .05), whereas there was no significant difference between the torsional strength values of the Mtwo and ProGlider groups (P > .05). The Rotate group had the lowest torsional strength among all groups (P < .05). The Mtwo group showed the lowest angle of rotation among all groups (P < .05).ConclusionsAlthough the R-Pilot glide path file exhibited the highest torsional strength in all groups, Rotate showed the highest angle of rotation. Differences in torsional resistance of the instruments may be associated with their manufacturing methods and design features. 相似文献
The aim of this study was to determine left ventricular (LV) morphology and aortic function in power athletes and to compare them with normal subjects. Thirty-two elite male wrestlers and 15 age-matched healthy male controls were included. All subjects underwent echocardiographic examination. Measurements included LV cavity dimension at systole and diastole, wall thickness, diastolic parameters, and aortic diameter, 3cm above aortic valve, at systole and diastole. Left ventricular mass and mass index were found to be higher in the athletes than in control subjects. The aortic distensibility index was found to be reduced in the athletes compared with controls (2.53 ± 0.91 vs 3.94 ± 1.77cm2dyne–1 10–6, P = 0.003), while the aortic stiffness index was significantly higher in the athletes than in controls (9.12 ± 3.23 vs 6.65 ± 2.35, P = 0.02). However, LV end-systolic wall stress was lower in the athletes than in controls. Furthermore, transmitral early (E) and late (A) peak velocity, peak velocity of the myocardial systolic wave (Sm), and early (Em) and atrial (Am) diastolic waves at the inferior wall were higher in the athletes than in controls. Reduced aortic distensibility in elite power athletes may be one of the cardiovascular adaptation factors which affect LV hypertrophy. 相似文献
Background: Pentraxin 3 (PTX3) is an acute phase reactant which has been used to detect intra-amniotic infections (IAI) in pregnancy, but the prognostic value of PTX3 concentrations on neonates has not been studied. We aimed to investigate the relationship between maternal PTX3–neonatal PTX3 concentrations and early neonatal outcome.
Methods: The mothers diagnosed with preterm prelabor rupture of membranes (PPROM) (n?=?28) and their preterm infants (n?=?28) were included in the study. PTX3 concentrations were studied in plasma in the maternal peripheral blood and umbilical/peripheral vein in the neonates. The relationship between the mPTX3–nPTX3 concentrations and neonatal outcome were investigated using non-parametric tests and binary logistic regression analysis.
Results: The mean mPTX3 concentration was 10.35?±?7.82?μg/L. Ten (35.7%) of all mothers were within the normal range and 18 (64.3%) in high percentile (≥97.5 percentile). There was no relation between mPTX3 concentrations and clinical or histologic chorioamnionitis, latency of PPROM, and early neonatal outcome. Mean nPTX3 concentrations was 9.18?±?7.83?μg/L and high nPTX3 concentrations were detected in five (17.8%) neonates. nPTX3 concentrations were inversely correlated with gestational age and correlated with rate of intraventricular hemorrhage (IVH) and mortality. Neonates with high nPTX3 concentrations also have lowered APGAR scores, increased rate of respiratory distress syndrome, clinical sepsis, IVH, necrotizing enterocolitis and prolonged NICU stay.
Conclusion: High PTX3 concentrations of the newborns are associated with some worsened early neonatal outcome including lower gestational age at delivery, increased rate of IVH and mortality. Maternal PTX3 concentrations are not an adequate marker in defining clinical or histologic chorioamnionitis and early neonatal outcome. 相似文献

[Purpose] The aim of this retrospective study was to determine the associations between
clinical, physical, and neurophysiological outcomes and self-reported symptoms and
functions of patients after surgical carpal tunnel release. [Subjects and Methods] Among
261 patients who had undergone open surgical carpal tunnel release within the last three
years, 83 (mean age 50.27 ± 11.13 years) participated in this study. Their
socio-demographics and comorbidities were recorded. The intensity of pain, paresthesia,
and fatigue symptoms in the hand were assessed by means of a Visual Analogue Scale, the
Semmes-Weinstein Monofilaments test of light touch pressure sensation, and Jamar
dynamometry for measurement of grip and pinch strengths. The Boston Carpal Tunnel
Questionnaire evaluated the severity of symptoms and hand functional status, and the
variables were analyzed by multivariate linear regression. [Results] The severity of the
symptoms and functional status of release surgery patients was associated with diabetes
mellitus, migraine, night pain, paresthesia and fatigue symptoms, impaired light touch
pressure, and lack of medical treatment. [Conclusion] Appropriate post-surgery treatment
programs for these factors should be taken into consideration to help patients obtain
optimal functionality and health in their daily lives.Key words: Carpal tunnel syndrome, Patient outcome assessment, Surgical therapy相似文献
Studies reporting the need for replacing amino acids such as glutamine (Gln), hydroxymethyl butyrate (HMB) and arginine (Arg) to accelerate wound healing are available in the literature. The primary objective of this study was to present the effects of Gln on tissue hydroxyproline (OHP) levels in wound healing. This study was conducted on 30 female Sprague Dawley rats with a mean weight of 230 ± 20 g. Secondary wounds were formed by excising 2 × 1 cm skin subcutaneous tissue on the back of the rats. The rats were divided into three equal groups. Group C (Control): the group received 1 ml/day isotonic solution by gastric gavage after secondary wound was formed. Group A (Abound): the group received 0·3 g/kg/day/ml Gln, 0·052 g/kg/day/ml HMB and 0·3 g/kg/day/ml Arg by gastric gavage after secondary wound was formed. Group R (Resource): the group received 0·3 g/kg/day/ml Gln by gastric gavage after secondary wound was formed. The OHP levels of the tissues obtained from the upper half region on the 8th day and the lower half region on the 21st day from the same rats in the groups were examined. Statistical analysis was performed using the statistics program SPSS version 17.0. No statistically significant differences were reported with regard to the OHP measurements on the 8th and 21st days (8th day: F = 0·068, P = 0·935 > 0·05; 21st day: F = 0·018, P = 0·983 > 0·05). The increase in mean OHP levels on the 8th and 21st days within each group was found to be statistically significant (F = 1146·34, P = 0·000 < 0·001). We conclude that in adults who eat healthy food, who do not have any factor that can affect wound healing negatively and who do not have large tissue loss at critical level, Gln, Arg and HMB support would not be required to accelerate secondary wound healing. 相似文献
