Rapid technetium-99 m methoxyisobutylisonitrile (99 mTc-MIBI) washout has been shown to occur in impaired myocardia. This study is based on the hypothesis that scintigraphy can be applied to calculate the myocardial 99 mTc-MIBI washout rate (WR) to diagnose and evaluate heart failure severity and other left ventricular functional parameters specifically in idiopathic dilated cardiomyopathy (IDCM) patients. Patients with IDCMP (n = 17; 52.65 ± 11.47 years) and normal subjects (n = 6; 49.67 ± 10.15 years) were intravenously administered 99 mTc-hexakis-2-methoxyisobutylisonitrile (99 mTc-MIBI). Next, early and delayed planar data were acquired (at 3.5-h intervals), and electrocardiogram (ECG)-gated myocardial perfusion single photon emission computed tomography (SPECT) was performed. The 99 mTc-MIBI WR was calculated using early and delayed planar images. Left ventricular functional parameters were also analyzed using quantitative gated SPECT (QGS) data. In target group, myocardial WRs (29.13 ± 6.68%) were significantly higher than those of control subjects (14.17 ± 3.31%; P < 0.001). The 99 mTc-MIBI WR increased with the increasing severity of the NYHA functional class (23.16 ± 1.72% for class I, 30.25 ± 0.95% for class II, 32.60 ± 6.73% for class III, and 37.50 ± 7.77% for class IV; P = 0.02). The WR was positively correlated with the end-diastolic volume (EDV) index (r (2) = 0.216; β = 0.464; P = 0.02 [ml/m(2)], the end-systolic volume (ESV) index (r (2) = 0.234; β = 0.484; P = 0.01 [ml/m(2)]), the summed motion score (SMS) (r (2) = 0.544; β = 0.738; P = 0.00), and the summed thickening score (STS) (r (2) = 0.656; β = 0.810; P = 0.00); it was negatively correlated with the left ventricular ejection fraction (LVEF) (r (2) = 0.679; β = -0.824; P = 0.00). It can be concluded that 99 mTc-MIBI scintigraphy might be a valuable molecular imaging tool for the diagnosis and evaluation of myocardial damage or dysfunction severity. 相似文献

In the past eleven years we have performed 438 microsurgical ventral discectomies with bilateral foraminotomy followed by fusion with palacos in the cervical spine in our clinic.An analysis of the preoperative symptoms shows a great variability and overlapping of the various segments. To determine the right level for the operation it is crucial that the results of the clinical and the radiological examinations be evaluated. The results of ascending myelography and CT scans are of great value.In cases of cervical myelopathy a multisegmental operation is often necessary to optain good results. The complication rate was small in our patients and a second operation was only necessary in a few cases.We had very good postoperative results in radicular pain and muscle weakness. In patients with symptoms of cervical myelopathy we achieved considerable improvement. 相似文献

Background: Despite beneficial effects of conjugated linoleic acids (CLAs) in animal studies, there is little information on their effects on human inflammatory and autoimmune diseases. Aim: To investigate the effects of CLAs as an adjuvant therapy on the clinical manifestations of rheumatoid arthritis (RA) in adults with an active disease. Methods: In a randomized, double‐blind placebo‐controlled trial, 87 patients with active RA were divided into four groups receiving one of the following daily supplements for 3 months: group C: CLAs 2.5 g equivalent to 2 g mixture of cis 9‐trans 11 and trans 10‐cis12 CLAs at a rate of 50/50; group E: vitamin E: 400 mg; group CE: CLAs and vitamin E at above doses; group P: placebo. Serum α‐tocopherol was determined by high‐performance liquid chromatography. Clinical data was determined by physician examination and filling the questionnaire by interview. Complete blood count (CBC), erythrocyte sedimentation rate (ESR), C‐Reactive protein (CRP) and rheumatoid factor (RF) were measured in each patient. DAS28 (diseases activity score) was also determined. Results: A 3‐month supplementation resulted significant reduction in DAS28, pain and morning stiffness in the groups C and CE compared with group P (P < 0.05). Compared with the baseline, ESR levels decreased significantly in the groups C (P ≤ 0.05), E (P ≤ 0.05) and CE (P ≤ 0.001). Group CE had significantly lower ESR levels than group P (P ≤ 0.05). CRP dropped non‐significantly in all four groups (P > 0.1). The reduction of white blood cell count was significant in group CE compared with other groups (P < 0.05). Decrease in platelet count was non‐significant in groups CE, C, and E. Changes in RF, body mass index, red blood cell count and hemoglobin were not significant in four groups, while RF decreased non‐significantly in groups CE and E. In comparison with the baseline, α‐tocopherol increased significantly in groups C (P ≤ 0.05), E (P ≤ 0.01) and CE (P ≤ 0.001) and in groups E and CE compared with group P. Conclusion: CLA supplementation resulted in significant improvement in clinical manifestation among RA patients and may be useful in their treatments. 相似文献

OBJECTIVE: To compare therapeutic effects of eicosapentaenoic acid (EPA), fluoxetine and a combination of them in major depression. METHOD: Sixty outpatients with a diagnosis of major depressive disorder based on DSM-IV criteria and a score >or=15 in the 17-item Hamilton Depression Rating Scale (HDRS) were randomly allocated to receive daily either 1000 mg EPA or 20 mg fluoxetine, or their combination for 8 weeks. Double dummy technique was used to double blind the study. Patients were assessed at 2 week intervals. Change in HDRS was the primary outcome measure. RESULTS: Analysis of covariance for HDRS at week 8 across treatment groups was performed in 48 patients who completed at least 4 weeks of the study, with the last observation carried forward. Treatment, age of onset and baseline HDRS had a significant effect on HDRS at week 8. EPA + fluoxetine combination was significantly better than fluoxetine or EPA alone from the fourth week of treatment. Fluoxetine and EPA appear to be equally effective in controlling depressive symptoms. Response rates (>or=50% decrease in baseline HDRS) were 50%, 56% and 81% in the fluoxetine, EPA and combination groups, respectively. CONCLUSIONS: In the present 8 week trial EPA and fluoxetine had equal therapeutic effects in major depressive disorder. EPA + fluoxetine combination was superior to either of them alone. 相似文献

Intracranial occurrence of follicular dendritic cell (FDC) sarcoma, a rare tumor derived from dendritic cells of the lymphoid follicle, has not yet been described. Therefore, the case of a 53-year-old man presenting with an intracranial mass invading the clivus is reported. The diagnosis of FDC sarcoma was confirmed by immunohistochemical staining for dendritic cell markers, that is, CD21, CD23, and CD35. Due to some similarities with meningioma, intracranial FDC sarcoma might be an underdiagnosed disease. 相似文献

BackgroundGlucocorticoids (GCs) are widely prescribed for the treatment of numerous clinical disorders due to their anti-inflammatory and immune-modulatory properties and one of the most common untoward effects of these drugs is dyslipidemia.ObjectiveTo evaluate the effect of quercetin, a plant-derived flavonoid, on the lipid profile of high-dose glucocorticoid treated rats.MethodsA total of 32 Sprague-Dawley rats, were randomly distributed among four groups (8 rats per group) and treated for 6 weeks with one of the following: (i) normal saline; (ii) 40 mg/kg methylprednisolone sodium succinate (MP); (iii) MP + 50 mg/kg quercetin; (iv) MP + 150 mg/kg quercetin. MP was injected subcutaneously, and quercetin was administered by oral gavage 3 days a week. At the end of the study, the animals’ lipid profile was measured by enzymatic kits. Data were analyzed and statistical significance was set at p<0.05.ResultsThe mean serum total cholesterol (TC), triglyceride (TG) and LDL levels were drastically increased in GC-treated animals compared with the control group. Both doses of quercetin (50 and 150 mg/kg) ameliorated TC (43% and 45%), LDL (56% and 56%) and TG (46% and 55% respectively). Apo B/A1 ratio decreased more than 20% following quercetin intake and the decline in TC/HDL, TG/HL, LDL/HDL ratios were significant.ConclusionsThese data suggest that quercetin intake with both doses of 50 and 150 mg/kg could be considered as a protective agent for glucocorticoid-induced dyslipidemia.
