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

The purpose of this study was to examine at ultrastructural level the neural changes in human apical pulps of teeth clinically diagnosed as having ulcerative or hyperplastic pulpitis. Seventeen specimens were prepared from six teeth with ulcerative or hyperplastic pulpitis and four specimens from two sound teeth. After routine procedures the specimens were examined under an electron microscope for changes in the structure of myelinated and unmyelinated nerve fibres. Although the teeth used in this study responded positively to vitality test, the results revealed that moderate to severe degenerative changes occurred in the nerve fibres of the apical pulps of the teeth showing these two diseases. 相似文献

Abstract: Biliary obstruction has been recognized to inhibit excretion of antibiotics into bile. In the present study, using cefpirome sulfate (CPR), we sought to determine the effect of biliary pressure on antibiotic transfer into bile in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Thirty-six patients with a variety of biliopancreatic diseases (free of renal disease or hypoproteinemia) received a single intravenous dose of CPR (1 g) prior to ERCP. Under fluoroscopy a diagnostic catheter with a metal ball tip was advanced into the middle portion of the extrahepatic bile duct or, in cases of common bile duct obstruction, above the obstruction. Biliary pressure was measured via the same catheter using duodenal pressure as a reference. Subsequently, bile was aspirated, and blood was withdrawn simultaneously. The mean interval between CPR administration and the bile and blood samplings was 67±12 minutes. The bile CPR concentration and the bile/serum ratio of CPR concentrations showed a significant inverse correlation with biliary pressure, but the serum CPR concentration did not. The bile CPR concentration and the bile/serum ratio of CPR concentrations differed significantly between the group with normal biliary pressures, below 10 mmHg, and that with biliary pressures exceeding 10 mmHg. The serum CPR concentrations of the two groups were similar. These results suggest that biliary pressure plays an important role in determining antibiotic transfer into bile. 相似文献

本文报导了18个氯丙嗪裂环类似物的神经药理作用。試驗結果表明:按(Ⅰ)所示虛线剖裂吩噻嗪(即苯噻嗪,phenothiazine)环系后,它們的鎮靜鎮定作用消失,抗組織胺作用明显減弱,局部麻醉作用有所增强。其中N-(β-对-氯苯硫乙基)N-(β-哌啶基丙酰基)-苯胺盐酸盐(NM-568)的局部麻醉效能更为明显,用多种方法与沙夫卡因和普魯卡因比較試驗,获得它們的局部麻醉效价比例如下:(1)家兔角膜試驗:NM-568的表面麻醉效力約接近沙夫卡因,較普魯卡因强1060倍。(2)豚鼠皮內丘样試驗:普魯卡因的效价为1;NM-568,27.5;沙夫卡因,22。(3)小白鼠坐骨神經传导阻滞試驗:如以普魯卡因的效价为1;NM-568,16;沙夫卡因,39.(4)蟾蜍脊髓麻醉:普魯卡因的效价为1;NM-568,9;沙夫卡因,8。对小白鼠的急性毒性,NM-568較沙夫卡因約小1倍,比普魯卡因約大3倍;它对家兔皮內注射和角膜的刺激作用較普魯卡因和沙夫卡因大。氯丙嗪按上列方式裂环后,发現N-(β-对-氯苯硫乙基)N-(γ-嗎啉基)-苯胺盐酸盐(NM-572),N-(β-对-氯苯硫乙基)N-(γ-哌啶基丙基)-苯胺盐酸盐(NM-578)在較大剂量时有抗电休克作用,但作用持續时间仅2小时。 相似文献

The effect of obstructive jaundice on local neutrophil accumulation in response to inflammatory stimulus was investigated in rats. Obstructive jaundice was produced by bile duct ligation for 7 days. Zymosan (200 mg) was injected intraperitoneally and 4h later myeloperoxidase activity in the peritoneal fluid was measured to quantify neutrophil recruitment. Zymosan-induced neutrophil recruitment was significantly greater (more than two-fold) in bile duct-ligated rats than in sham-ligated or normal animals. Depletion of peritoneal cells significantly suppressed neutrophil recruitment after zymosan injection in all three groups, with no significant differences between the groups. In normal rats, replacement of their peritoneal cells by those from bile duct-ligated rats did not enhance zymosan-induced neutrophil recruitment. In contrast, bile duct-ligated rats treated with peritoneal cell replacement from normals showed significantly increased neutrophil recruitment after zymosan injection. In vitro neutrophil chemotaxis in response to formyl-Met-Leu-Phe was significantly enhanced in bile duct-ligated rats, compared with that in sham-ligated animals. The results suggest that local neutrophil recruitment in response to inflammation may be enhanced in obstructive jaundice and that increased neutrophil chemotactic activity, not macrophage activity, may play a prime role in the mechanism. 相似文献

Parkinson’s disease (PD) patients often suffer from spinal diseases requiring surgeries, although the risk of complications is high. There are few reports on outcomes after spinal surgery for PD patients with deep brain stimulation (DBS). The objective of this study was to explore the data on spinal surgery for PD patients with precedent DBS. We evaluated 24 consecutive PD patients with 28 spinal surgeries from 2007 to 2017 who received at least a 2-year follow-up. The characteristics and outcomes of PD patients after spinal surgery were compared to those of 156 non-PD patients with degenerative spinal diseases treated in 2013–2017. Then, the characteristics, outcomes, and spinal alignment of PD patients receiving DBS were analyzed in degenerative spinal/lumbar diseases. The mean age at the time of spinal surgery was 68 years. The Hoehn and Yahr score regarding PD was stage 1 for 8 patients, stage 2 for 2 patients, stage 3 for 8 patients, stage 4 for 10 patients, and stage 5 for 0 patient. The median preoperative L-DOPA equivalent daily dose was 410 mg. Thirteen patients (46%) received precedent subthalamic nucleus (STN) DBS. Lumbar lesions with pain were common, and operation and anesthesia times were long in PD patients. Pain and functional improvement of PD patients persisted for 2 years after surgery with a higher complication rate than for non-PD patients. PD patients with STN DBS maintained better lumbar lordosis for 2 years after spinal surgery. STN DBS significantly maintained spinal alignment with subsequent pain and functional amelioration 2 years after surgery. The outcomes of spinal surgery for PD patients might be favorably affected by thorough treatment for PD including DBS. 相似文献
