Pulmonary Lophomonas blattarum infection in patients with kidney allograft transplantation

The aim of the study was to analyse the clinical manifestation and management of pulmonary Lophomonas blattarum infection in four allograft transplantation recipients retrospectively. Four patients with pulmonary L. blattarum infection were diagnosed by using Fiberoptic bronchoscopy (FOB) and bronchoalveolar lavage (BAL) examination. Their clinical manifestation and management are summarized. Four cases of pulmonary L. blattarum were found during the period from the second month to the third month after transplantation. Concurring infection by other pathogens was found in three of them. Common initial symptoms included fever (>38 degrees C) without cough and breathlessness. Lower lobe shadowing could be found on chest X-ray. Body temperature decreased to the normal range in three patients and to 37.5 degrees C in the other one, after intravenous injection of metronidazole and tapering immunosuppressant. Radiological examination confirmed improved health condition of the patients afterwards. Two patients received repeated FOB and only dead L. blattarum was found. Pulmonary L. blattarum infection in allograft transplant recipients carry relatively obscure initial symptoms. Possible L. blattarum infection needs to be screened in post-transplantation pulmonary infection patients with similar symptoms, especially in those who respond poorly to anti-infection treatment. Microscopic examination of BAL fluid can help to identify pulmonary L. blattarum infection and metronidazole is an ideal treatment choice.

绞股蓝总皂甙对自由基损伤血管内皮的保护作用

本文观察了绞股蓝总皂苷(Gypenosides,GYP)对电解性自由基(OFR)损伤离体兔胸主动脉和脑基底动脉内皮的保护作用:电解性OFR使乙酰胆碱(Ach)诱导的兔主动脉环舒张百分率明显降低,舒张比值(RR)变小,使离体兔脑基底动脉灌流压升高。结果显示绞股蓝能保护血管内皮免受OFR损伤,且呈剂量依赖性,并明显抑制OFR所致灌流压升高。作用似二甲亚砜(DMSO),说明GYP对外源性OFR损伤具保护作用。     

百年乐与人参黄芪合剂对心血管系统的药理作用比较

百年乐和人参黄芪合剂对心血管系统的作用研究表明:百年乐能加速小鼠肠系膜微循环障碍的恢复,增加离体兔耳血管的流量,使主动脉平滑肌松弛,对抗心肌缺氧,抑制血栓形成,其作用强于人参黄芪合剂。     

乳腺癌HSV—1,HSV—2与c—erbB—2关系的免疫组化研究

采用免疫组织化学Ｓ－Ｐ法检测５２例手术切除乳腺癌组织ｃ－ｅｒｂＢ－２蛋白和ＨＳＶ－１、ＨＳＶ－２表达情况。结果发现癌组织中ｃ－ｅｒｂＢ－２阳性３４例（６５．４％）；ＨＳＶ－１阳性３８例（７３．１％）；ＨＳＶ－２阳性１５例（２８．８％）。癌旁组织３２例，阳性分别为３例（９．４％）；１２例（３７．５％）；２例（６．３％）。乳腺癌中ｃ－ｅｒｂＢ－２阳性率明显高于癌旁组织。乳腺癌及癌旁的ＨＳＶ－１阳性率明
