The concentrations of sodium and potassium and the content of ferritin and transferrin, proteins considered as potential markers for identifying cells undergoing divisional activity, were measured in fluid from 30 human breast cysts. On the basis of the relative electrolyte concentrations, two main classes of cysts were defined. When the cyst fluids were subdivided according to their Na+/K+ ratio, a significant difference was found between menstruating vs. menopausal patients. The relationship between the two major iron-binding proteins and the Na+/K+ ratio may indicate the expression of a local higher biosynthetic activity in apocrine cysts associated with higher cancer risk. 相似文献

Cervical and vaginal smears in 300 women using (a) intrauterine devices (IUD) and in 300 age matched control subjects (b), have been examined. In women using IUD, endometrial cells have been observed also in the second half of menstrual cycle, conversely these cells are present in women belonging to the control group, just in the first half of the cycle. Pattern of cervico-vaginitis due to Chlamydiae, Actinomyces and Eubacteria have been observed in higher percentage in women IUD wearers 58% of (a) group and 19.3% of (b) group (P less than 0.005). These patterns have often been characterized by the presence of repair cells. Implications in the evaluation of vaginal smears are discussed. 相似文献

Confirming partial small bowel obstruction is often a diagnostic challenge. In this case report, 4-mm solid radiopaque markers were used in 4 patients to show partial small bowel obstruction. Results of enteroclysis were normal in 2 of the 4 patients, and the markers were used to challenge suspected partial obstruction. The markers coalesced in the region of the partial obstruction, which was confirmed at surgery. Enteroclysis is the examination of choice in the diagnosis of partial small bowel obstruction. However, examinations with false- negative results can occur, particularly with adhesive and/or intermittent obstructions. The use of radiopaque markers in these cases proved an effective and useful method of establishing the diagnosis of partial small bowel obstruction, particularly in the 2 cases in which enteroclysis results were normal. Prospective studies are needed to establish the feasibility of this novel technique. (Gastroenterology 1996 Jun;110(6):1958-63) 相似文献

Objective: This prospective randomized trial compared the Angio‐Seal VIP? with Perclose Proglide? and to manual compression with respect to time to hemostasis and ambulation, patient satisfaction, and vascular complications following percutaneous coronary intervention (PCI). Background: The use of arterial closure devices for the reduction of vascular complications following PCI remains controversial. There have been no head to head trials comparing these most commonly used arterial closure devices following PCI. Methods: Two hundred patients undergoing PCI were randomized to manual compression, Perclose Proglide? or Angio‐Seal VIP?. Ambulation was allowed 3 hr after Perclose Proglide? or Angio‐Seal VIP? and 6 hr after compression. Results: There were 10 failures to deploy Perclose Proglide? and none for Angio‐Seal? (P < 0.01). Time to hemostasis was significantly shorter with Angio‐Seal VIP? compared with Perclose Proglide? (5.3 vs. 46.8 min, P < 0.01). Time to ambulation was shorter with Angio‐Seal VIP? than with Perclose Proglide? (261 vs. 334 min, P < 0.05) and the time to ambulation, as expected, was longest with compression (943 min, P < 0.01 vs. Angio‐Seal VIP? and Perclose Proglide?). Delay in ambulation was higher with Perclose Proglide? than with Angio‐Seal VIP? (18 vs. 9, P < 0.01). There was no significant difference in major vascular complications between groups. Compared with compression, patient discomfort was significantly improved with Angio‐Seal? (1.5 vs. 2.0, P < 0.01), but not with Perclose Proglide?. Conclusion: The Angio‐Seal VIP? device has a high rate of deployment success, which is significantly better than that of Perclose Proglide?. Angio‐Seal VIP? allows for earlier hemostasis and ambulation compared with both compression and Perclose Proglide? and is associated with greater patient satisfaction compared with compression. © 2008 Wiley‐Liss, Inc. 相似文献

Recently, the contractile protein alpha-actinin was identified in normal human platelets by its antigenic cross-reaction with a monospecific antibody to purified muscle alpha-actinin. In this study, we extend that preliminary identification of platelet alpha-actinin. Amino acid analysis, one-dimensional peptide maps, and silver stain analysis on polyacrylamide gels demonstrate that human platelet alpha- actinin shows a greater degree of similarity to smooth muscle alpha- actinin than to striated muscle alpha-actinin. There is no evidence to suggest that alpha-actinin is a glycoprotein. In addition, we find that thrombasthenic platelets, which are deficient in glycoproteins IIb and IIIa (GPIIb and GPIIIa) contain normal amounts of alpha-actinin, confirming the recent finding that alpha-actinin and GPIIIa are different proteins in human platelets. We demonstrate that both normal and thrombasthenic platelets also contain vinculin, a 130,000-dalton polypeptide found in many cell types at sites of end-on attachment of microfilaments to the plasma membrane. Thus, the thrombasthenic defect in GPIIb and GPIIIa does not diminish the content of either alpha- actinin or vinculin. 相似文献
