目的：通過收集潰傷性結腸炎（ Ulcerative colitis, UC ）的相關研究文獻，認識本病的發病機制、病名源流、流行病學及相關中醫藥治療情況，了解2006-2016 年間UC 的中藥口服治療現狀和用藥規律，對本病的常用藥和證治規律做統計分析，為臨床治療和研究該病提供有價值的參考依據。方法：檢索〈中國期刊全文數據庫〉’搜集2006-2016 年間有關中醫藥治療潰傷性結腸炎的研究文獻，按照合理的納入和排除標準’選出符合要求的文章，用Microsoft Office Excel2013 軟件建立UC 中藥口服用藥規律數據庫，對文章中涉及的中藥進行用藥頻率、藥物性味歸經及藥物類型的統計分析，以認識UC 常用內服中藥的情況，分析其用藥和證治規律。結果： (1 ）按照文獻的納入和排除標準進行篩選，總共選出符合要求的文章137 篇，涉及口服治療潰、屬性結腸炎的中藥141 種，總藥物使用次數1623 次，常用藥物依次為：白術、甘草、黃連、白苟、木香、夜苓、黨參、白頭翁、當歸、黃良、憲政仁、陳皮、黃琴、敗醬草、地輸、黃柏、枳殼等。藥物分類以清熱藥和補虛藥為主，清熱藥中使用頻率最高的是清熱燥濕藥與清熱解毒藥，補虛藥中使用頻率最高的是補氣藥，藥性寒、溫頻率相仿，藥味以甘苦辛為主，用藥歸經多為肝經、脾經、胃經和肺經。結論： (1 ）常用口服治佇潰傷性結腸炎的藥物以清濕熱藥和補氣藥為主，排名前十的依次為：白術、甘草、黃連、白苟、木香、夜苓、黨參、白頭翁、當歸、黃皮。（ 2 ）潰傷性結腸炎證型特點：虛實互存、寒熱錯雜，本虛標實，脾虛為本、濕熱為標，實證者以濕熱窒滯、濁毒絡腸為主，而虛證多見氣血虧虛、脾胃虛弱。(3 ）治療應辨清寒熱、虛實、標本，實者清熱燥濕、解毒通絡，虛者調補氣血，健脾理究，並酌情配伍止血收澀等藥。關鍵詢：潰傷性結腸炎﹔中藥﹔規律﹔性味歸經

Philosophiae Doctor - PhD / Over the years, microorganisms have become resistant to commonly used antimicrobial agents leading to multidrug resistance. This is believed to occur even with new classes of therapeutic agents thus creating a challenge on the global healthcare system. The study of medicinal plants allows for their possible use as alternative therapeutic agents. Galenia africana (G. africana) is a South African medicinal plant with numerous health benefits. The purpose of this study was to evaluate the potential antimicrobial, antifungal and anticancer properties of the ethanolic extract of G. africana. Prior to evaluating these properties, in vitro and in vivo acute toxicity studies were conducted to assess the toxicity profile of G. africana. The toxicity profile of the G. africana extract was evaluated using acute toxicity studies conducted in animal and reconstituted human epidermis skin models. The results of the acute oral and dermal toxicity studies revealed that the median lethal dosage (LD50) for G. africana extract in Sprague-Dawley rats was considered to exceed 2000 mg/kg. In the dermal sensitization study, the stimulation index (SI) values for the mice treated with the G. africana extract at concentrations of 25% (50 mg/ml), 50% (100 mg/ml), and 100% (200 mg/ml), when compared to the control group, were 1.3, 0.9 and 1.3, respectively which did not result in an SI value of ? 3 in any group. Hence, it did not elicit a hypersensitivity response. In the irritation test, the G. africana (concentrate) and G. africana (in-use dilution) extracts were non-irritant on the reconstituted human epidermis.

Various extracts of Entada abyssinica stem/root bark have been shown to have antimicrobial activity using organisms : Staphylococcus aureus, S. epidermidis, Escherichia coli, Pseudomonas aeruginosa, Bacillus megaterium, Candida albicans, Aspergillus niger and Tricophyton mentagrophytes on solid media. Chromatographic analysis of the bark extracts of different trees (according to age), showed them to contain in common the components responsible for the observed antimicrobial activity with differences observed in minor bands not of antimicrobial importance.

The methanol extract of Helichrisum pedunculatum was screened for antimicrobial activity up to a concentration of 5 mg/ml using the agar dilution technique. A number of test bacterial isolates, comprising both Gram negative and Gram positive organisms were susceptible to the crude extract of the plant. The minimum inhibitory concentrations (MICs) of the extract ranged between 1 and 5 mg/ml for the susceptible organisms. The MICs of the selected antibiotics, chloramphenicol and penicillin, ranged between 2 and 4 mg/L, and 2 and 32 mg/L respectively against Bacillus cereus, Proteus vulgaris and Staphylococcus aureus OKOH1. Bactericidal activity was determined by the time kill assay. The methanol extract of the plant was not bactericidal at 1 × MIC for B. cereus, P. vulgaris and Staph. aureus OKOH1. At 2 × MIC the extract was bacteriostatic against B. cereus but bactericidal against P. vulgaris and Staph. aureus OKOH1. Combination studies were done at 1/2 × MIC, 1 × MIC and 2 × MIC of the plant extract with 1 × MIC of the antibiotics. Combinations of the plant extract and chloramphenicol resulted in mostly indifferent interactions against P. vulgaris and Staph. aureus OKOH1 but synergistic interactions at higher concentration of the plant extract for B. cereus. Penicillin combinations gave synergistic interactions at lower concentrations of the plant for P.vulgaris and Staph. aureus OKOH1 but was mostly indifferent for B. cereus.
