Myoepitheliomas of the soft palate: helical CT findings in two patients.

We describe the enhancement patterns of myoepithelioma in two patients with a soft palate mass. In the first case, helical CT revealed a faintly enhancing mass. Histologically, the tumor was composed of plasmacytoid cells in a background of rich myxoid stroma. Immunostaining for CD34 showed scanty blood vessels. In the second case, helical CT revealed an intensely enhancing mass. Histologically, the mass was a cellular tumor with fibrous stroma. Immunostaining for CD34 also showed frequent blood vessels.     

小陷胸汤加味含药血清对人脐静脉内皮细胞分泌NO/ET-1的调节作用

目的:探讨小陷胸汤加味中药方对血管内皮细胞的保护作用。方港:建立ox-LDL损伤人脐静脉内皮细胞株(ECV-304)模型,用小陷胸汤加味含药血清处理模型,并用放免和硝酸酶还原法在药物干预6h和24h后检测细胞上清液中ET-1和NO含量。结果:100 μg/ml的ox-LDL可损伤血管内皮细胞并导致其分泌NO和ET-1功能失调,小陷胸汤加味含药血清通过影响NO/ET-1的分泌而明显改善此失调状态。结论:小陷胸汤加味中药通过调节NO/ET-1水平显著拮抗ox-LDL对血管内皮细胞损害,具有防治AS的作用。     

Effects of green tea polyphenols on murine transplant-reactive T cell immunity

Green tea polyphenols (GrTP), the active ingredient of green tea, may have immunosuppressive properties, but whether and how GrTP affect transplant-reactive T cells is unknown. To address this, we tested the effects of GrTP on in vitro and in vivo transplant-reactive T cell immunity. GrTP inhibited IFNgamma secretion by cultured monoclonal T cells and by alloreactive T cells in mixed lymphocyte reactions. Oral GrTP significantly prolonged minor antigen-disparate skin graft survival and decreased the frequency of donor-reactive interferon gamma-producing T cells in recipient secondary lymphoid organs compared to controls. In contrast to other hypothesized actions, oral GrTP did not alter dendritic cell trafficking to lymph nodes or affect metalloproteinase activity in the graft. This is the first report of an immunosuppressive effect of GrTP on transplant-reactive T cell immunity. The results suggest that oral intake of green tea could act as an adjunctive therapy for prevention of transplant rejection in humans.     

Adenoid cystic carcinoma of minor salivary glands. Analysis of 86 cases

Summary 819 salivary gland tumors in surgical pathology files over a 25-year period were reviewed. Among 117 adenoid cystic carcinomas, 86 were located in minor salivary glands and were selected for a clinico-pathological analysis. Complementary histoenzymological investigations and electron microscopic study were performed on specimens from 7 and 13 patients respectively.Adenoid cystic carcinoma occured in older patients (mean age of 54 years) than the other salivary neoplasms. The sex ratio was 1/1. The tumor was located more often in the palate and, to a lesser degree in the buccal floor, tongue or gums.Histologically, epithelial nests contained characteristic cyst-like spaces (cylinders) and 3 varieties of such cylinders were described (mucoid, mucohyalin and hyalin). According to the predominant pattern, 3 types of tumors were shown: basaloïd, cribriform and trabecular. A comparison between histological results and clinical behaviour, available in 67 patients, demonstrated positive correlations. The basaloïd form had always a poor prognosis (numerous early recurrences and metastases, frequent lethal evolution). The cribriform type had an intermediate prognosis, better than basaloïd type and less good than trabecular group (100% of patients still alive at 8 years).Histoenzymological studies revealed high level of acid phosphatase, alkaline phosphatase and leucine aminopeptidase activities round cylindromatous cavities. On the other hand, high oxidative enzyme activities were evenly distributed in all cell types.Ultrastructural findings emphasized the immature characters of epithelial tumor cells. These cells contained numerous ribosomes, but few other organelles. Some more differentiated glandular or epidermoid cells were scattered in neoplastic islands. Rare myoepithelial cells lay in periphery of lobules. Cylinder-like spaces were filled with replicated basal lamellae, mucopolysaccharidic granules and fibrillar structures (microfibrils and periodic collagen fibrils).In the light of these results the histogenesis of this neoplasm was discussed. Like the pleomorphic adenoma, adenoid cystic carcinoma was thought to arise from intercalated ducts. Unable to acquire any high degree of differentiation, this blastomatous tumor had a cellular component almost similar to that shown in intermediate stage of salivary gland embryogenesis.The authors wish to thank M.A. Leost and M. Tacnet for their technical assistance     

Mega-Liposuction: Analysis of 1520 Patients

Fifteen hundred and twenty cases of liposuction/liposculpture were performed at Dr. M. Erfan & Bagedo Hospitals and King Abdulaziz University Hospital in Jeddah from January 1983 to December 1994. These cases were mostly females. The age group was from 16–65 years. Multiple procedures were performed in 11.68% of these cases. The change in hemoglobin and the hematocrit ratio pre- and post-operatively, and the incidence of complications, were studied. The percentage of surface area operated upon rather than the amount of fat removed was the most important relevant factor.

曾学文运用经方治疗心系疾病

炙甘草汤、四逆汤、四逆散、真武汤、枳实薤白桂枝汤、葶苈大枣泻肺汤、小青龙汤出自张仲景的《伤寒论》及《金匮要略》,为曾学文治疗心系疾病的常用方。曾学文主任认为其理法方药,阐述了张仲景心系疾病辨证论治的理论和方法,心系疾病发病多因本虚标实,病位在心,"心动则五脏皆摇",可牵及肺、脾、肝、肾,本虚多以心气、心阳不足为主,可累及心阴,标实多以寒邪、痰饮、水湿、血瘀为主,"气、血、水"乃心脏疾病三步曲。
