The conducted studies indicated the diagnostic opportunities of a cytologic analysis of exudates and smears from the Douglas space in patients with a suspicion to ovarian tumor. Tumor cells may be present in the peritoneal cavity not only in different stages of malignant ovarian tumors, but also in secernent and proliferating cystadenomas. A correlation between the peritoneal cell content in patients with different forms of ovarian neoplasms and press-smears from the dissected surface of the removed tumors and histological sections indicated the morphological identitiy of tumor elements and enabled the determination of the cytological criteria for the differential diagnosis of ovarian tumors prior to surgical intervention. 相似文献

Persistent, profuse ileostomy diarrhea developed gradually in a patient over a 12-hour period after proctocolectomy for ulcerative colitis. There was no evidence of ileostomy stenosis or dilation of the ileum proximal to the stoma. He was successfully treated with a reverse ileal segment of 10 cm, and gained 14 to 18 kg. ileostomy output became semisolid and decreased from 1,000 to 2,000 ml/day to 600 ml/day. The transit time changed from 12 minutes to 2 1/2 hours. Antiperistaltic segments of intestine prolong transit time and allow for greater absorption. While most patients with ileostomies are not troubled by severe diarrhea, the small proportion who are may be candidates for a reversed ileal segment. 相似文献

A series of 348 patients undergoing operative intervention because of thyroid masses is reviewed. The incidence of primary malignancy among these patients is 16.4%. Male sex and the presence of cervical adenopathy significantly increase the probability of malignancy. The presence of multiple nodules or a functional nodule on radioiodine thyroid scan significantly reduces the probability of cancer. A rational approach to thyroid nodules is presented based on these findings and new modalities that have become available. 相似文献

Under a variety of conditions, alveolar macrophages can generate early response cytokines (TNF-alpha, IL-1), complement components, and chemotactic cytokines (chemokines). In the current studies, we determined the requirements for TNF-alpha and the complement activation product C5a in chemokine production in vitro and in vivo. Two rat CXC chemokines (macrophage inflammatory protein (MIP)-2 and cytokine-induced neutrophil chemoattractant (CINC)) as well as three rat CC chemokines (MIP-1alpha, MIP-1beta, and monocyte chemoattractant protein (MCP)-1) were investigated. Chemokine generation in vitro was studied in rat alveolar macrophages stimulated with IgG immune complexes in the absence or presence of Abs to TNF-alpha or C5a. The rat lung injury model induced by IgG immune complex deposition was employed for in vivo studies. Abs to TNF-alpha or C5a were administered intratracheally or i.v., and effects on chemokine levels in bronchoalveolar lavage fluids were quantitated by ELISA. Both in vitro and in vivo studies demonstrated the requirements for TNF-alpha and C5a for full generation of CXC and CC chemokines. In vitro and in vivo blockade of TNF-alpha or C5a resulted in significantly reduced production of chemokines. Supernatant fluids from in vitro-stimulated macrophages revealed by Western blot analysis the presence of C5a/C5adesArg, indicating intrinsic generation of C5a/C5adesArg by alveolar macrophages and explaining the higher efficiency of intratracheal vs i.v. blockade of C5a in reducing chemokine production. These results underscore the central role of both TNF-alpha and C5a, which appear to function as autocrine activators to promote CXC and CC chemokine generation by alveolar macrophages. 相似文献

The results of surgical treatment of 118 patients with duodenal ulcer complicated with stenosis that have been operated on from 1981 to 1992 have been analysed. Selective proximal vagotomy (SPV) and duodenoplasty was performed in 58 (49.2%) patients (study group). SPV and gastroduodenal anastomosis by the method of Jabulay was performed in 60 (50.8%)-control group. The rate of postoperative morbidity in the study group-5.1%, in the control group-8.4%. The long-term follow up is from 1 year to 10 years (mean 5 + 0.6). The rate of recurrence of peptic ulcer is 8.6% in the study group and 10% in the control group. The modified scale (D. Johnson, 1976) was used for comparative evaluation of efficacy of two types of surgery. SPV and duodenoplasty was estimated in 175.1 points, that is 2.5 times less that SPV and gastroduodenal anastomosis (406.1 points). This demonstrates the advantages of SPV and duodenoplasty. The authors advocate SPV and duodenoplasty as a method of choice in the treatment of stenotic duodenal ulcer. 相似文献
