  ABSTRACT: To investigate the candidal carriage and the Candida species in HIV positive patients and to explore the relationship between oral candidal carriage and oral candidiasis. Sixty-four HIV positive patients and 42 healthy controls were included in this study. Oral rinse technique was used to detect the candidal carriage. The isolates were identified using multiple measures, including Gram staining reaction, chlamydospore, pseudo-hyphal and hyphal production test, CHROMagar Candida test and API 20 C AUX yeast identification system. Thirty-nine of 64 HIV positive cases were diagnosed as oral candidiasis. Seventy-four Candida strains were isolated from 52 of 64 HIV positive cases, only 7 strains were isolated from 42 healthy controls (P < 0.001). Of the 74 Candida strains isolated from HIV positive cases, 39 were Candida albicans, 15 Candida tropicalis, and 20 other 6 species. A high prevalence of oral candidiasis and high candidal carriage were found in HIV positive patients compared with those in controls. Candida albicans and Candida tropicalis were the major species. The biotyping of the species isolated from HIV positive patients showed more diversified compared to healthy people, which may suggest the decreased immune ability of the HIV positive patients.

  ABSTRACT: To investigate the prevalence, age and gender distribution and clinical features of HIV/AIDS oral lesions in patients in Guangxi province, and to provide the epidemiological information for prevention and treatment of these diseases in the certain population. A total of 64 HIV/AIDS patients were included in this study. All patients HIV serum-status was confirmed in Guangxi Center of Disease Control (GXCDC). Oral examination was carried out by standardized specialists. HIV/AIDS orofacial lesions were recorded and diagnosed using the EC Clearing House Criteria on Oral Problems related to HIV Infection (1992). Among the total of 64 HIV/AIDS patients included in this study, there were 53 males and 11 females, with mean age of 36.1 years. Candidiasis was the most common lesion with the pseudomembranous type predominating. High prevalences of xerostomia, 11 oral ulceration and 7 HIV related periodontitis were noted. 6 Herpetic stomatitis and 3 herpes zoster, 2 oral hairy leukoplakia and 1 Kaposi's sarcoma and 1 lymphadentitis also were found. This study shows a high prevalence of candidiasis, salivary gland disease. Maybe oral ulceration prevalence is not increased, but lesion severity is increased with more severe heperiform or major RAU. It suggested that HIV/AIDS usually shows oral lesion and partly can appear in early phase.

  ABSTRACT: 發展轉口貿易，策進台灣成為遠東一流國際運儲中心一向為我國有關當局提昇貿易層 次，分散國際市場的重要策略。然一優良的之國運儲中心除能提供航商優良之服務品 質外，有效合理地較低其運輸倉儲成本更能吸引廠商利用運儲設備。故本研究旨在探 討影響運儲倉儲成本的主要因素，以便發展相關服務策略，提高我國在遠東之轉運地 位！ 本研究之範圍包括台灣各港埠、機場，以問卷方式收集相關一級資料。初步以外部環 境及內部資源等23項評估指標進行因素分析（Factor analysis ），以萃取影響運輸 倉儲成本之主要因素。繼之以逐步迴歸（Stepwise anslysis ）分析法，探求各因素 之影響重要性順序，並比較我國各在因素構面上和競爭者（香港、新加坡）所處之競 爭地位。 研究結果發現，影響運輸倉儲成因素按其重要性順序排列分別為：?服務效率因素。 ?營運性因素。?設施能量因素。?費率性因素。?政策性因素。?環境機會／威脅 因素。我國除在第三及第六因素上較具競爭優勢外，在其他四項素上皆居劣勢故其有 待有關當局之改善及研擬因應措施，始能突破現階段之發展瓶頸！
