Human milk has always been the reference parameter for the preparation of commercial formulae. The advent of more advanced technologies has enabled increasingly precise information on the composition of human milk to be obtained. Our knowledge in the field of carbohydrates also has improved considerably in the last few years following the pioneering studies of Montreuil (1, 2). From a quantitative point of view it has been demonstrated that in the different phases of lactation, in addition to lactose, human milk contains a consistent amount of oligosaccharides (about 20 g/1 in colostrum and 10–13 g/l in mature milk) (3, 4), whereas monosaccharides make up only about 1% of the total carbohydrates (4). More than 100 different types of oligosaccharides have been identified so far in human milk (5–7), mostly tri-octasaccharides (8). From a biochemical point of view, oligosaccharides are constituted by glucose, galactose, N -acetyl-glucosamine, fucose and sialic acid, and present a linear or branching structure (5). Little is known yet about their physiological role or metabolic fate (9); nevertheless, it has been demonstrated that, in addition to their nutritional function, they participate also in the regulation of the intestinal ecosystem, encouraging the growth of bifid flora (10) and contributing to the defense mechanisms against pathogens in various organs (11–13). 相似文献

This is the first case reported of combined cervical emphysema and pneumomediastinum associated with unusual electrocardiographic and local neurologic findings. These may be the result of an increase in intracervical and intrathoracic pressure induced by the dissecting air. 相似文献

目的:探讨99mTcO4-甲状腺显像定量分析在甲状腺疾病诊断中的临床价值。方法:采用Marconi Fx810 SPECT仪对38例正常对照者和189例Graves病、亚急性甲状腺炎、单纯性甲状腺肿及甲状腺功能减退者进行99mTcO4-甲状腺动静脉态双时相显像,测定颈动脉与甲状腺显影时间差(Td)及20分钟时甲状腺与颈部软组织像素的平均放射性比值(UI)。结果:①Graves病组表现为Td缩短,UI值明显增高,且UI值恢复速度滞后于体外甲功指标的恢复(P<0.01)。②亚甲炎组甲状腺摄锝功能降低(P<0.01),静态显像表现为放射性普遍稀疏或局限性稀巯。③单甲肿组、甲减组Td、UI值与正常组无明显差异(P>0.05)。④对照组、Graves病、亚甲炎及单甲肿组24小时吸131I率与UI值有良好的相关性。结论99mTcO4-甲状腺显像定量分析法操作简便,误差小,适用范围广,在常见甲状腺疾病的诊断中具有重要价值。 相似文献

Three patients with massive pulmonary gangrene who have survived without recourse to surgery are presented. In 2 cases, anaerobic organisms were suspected as being the causative pathogens although this was not proved. With resolution the radiological appearances of the involved lobe varied from no more than segmental to almost complete loss of the whole lobe. 相似文献

AIM: To evaluate inflammatory activity in patients with Crohn’s disease (CD) using technetium-99m-hexamethylpropyleneamine oxime (99mTc-HMPAO) granulocyte scintigraphy.METHODS: Twenty patients (7 male and 13 female) with CD and five healthy volunteers were selected for 99mTc-HMPAO granulocyte scintigraphy. The Crohn’s Disease Activity Index (CDAI), blood tests and C-reactive protein (CRP) of each patient were performed 7 d before the scintigraphic images. The leukocytes were labeled according to the International Society of Radiolabeled Blood Elements (ISORBE) consensus protocol and the scintigraphic images, including single photon emission computed tomography, were obtained 30 min and 2 h after injection of the radiolabeled leukocytes.RESULTS: The labeling yield of the leukocytes with the lipophilic complex 99mTc-HMPAO was 55.0% ± 10%. Six of the 20 patients (30%) presented congruent results for the three parameters investigated (CDAI, Scintigraphic Index and CRP). On the other hand, 14 patients (70%) did not show congruent results. There was no significant correlation between the indices analyzed according to the Spearman test (P > 0.05, n = 20).CONCLUSION: The results suggest that 99mTc-HMPAO-labeled leukocyte scintigraphy could be important for determining inflammatory activity in CD even in the absence of clinical symptoms. 相似文献

Thrombosis of the cerebral dural sinuses and veins has been described since the early 19th century.1,2 Clinically the process is characterised by diverse symptomatology and physical findings and in spite of advances in diagnostic radiological techniques it remains an under-recognised condition. It has been most commonly associated with sepsis, trauma, pregnancy, the puerperium and many other hypercoagulable states. We describe an apparently unique case of sagittal sinus thrombosis occurring during an ectopic pregnancy. This was subsequently complicated by intracranial hypertension in spite of clinical improvement and magnetic resonance imaging (MRI) evidence suggesting a return of venous patency. The clinical presentation, radiological features and management is discussed. 相似文献
