Mastic is a bleed resin formed in pistacia lentiscus tree extract form the anacatdiaceae family. Mastic is used as a food ingredient in the Mediteraanean resin, and has been used by local inhabitants as a traditional medicine for relief of upper abdominal discomfort, dyspepsiaand peptic ulcer. Clinically, mastic has been effective in the treatment of benign gastric and duodenal, ulcers, giving symptomatic relief and endoscopically proven healing. In this study, to enhance activiteies of poorly water soluble Mastic with oils, surfactants and cosurfactants and then the mixure was microemulsified in aqueous media under condition of gentle agitation and digestive motility that would be encountered in the gastrointestinal tract. Formulation development and screening were based on phase diagrams and characteristics of resultant microemulsion. For optimum mastic formulation, microemulsions with various ratio (w/w%) of mastics, oils, surfactants and cosurfactants were prepared and their solubility was evaluated by monitoring particles size in their buffer through visual asessment and electrophoretic light scattering spectrophotomerter (ELS). In vitro activity of self microemulsified mastic (SME mastic) was determined by minimum ingibition concentration (MIC) test against a panel of Helicobacter pylori (H. pylori) clinical strains. Additionally, in vivo activity of SME masitc was investigated us mouse infected by CH275 of H. pylori. The mean diameter of SME mastic was less then 100 nm in water and SME mastic was showed similar antiboisis effect compared to tometronidazole, clarithromycin and omeproazole. Consequently, SME mastic would be effective system to exterminate H. pylori. If mastic were dose with combined treatment, mastic might augur well for effect of H. pylori eradication as good remedy.

위염, 위궤양, 십이지장 궤양, 위선암, 위림프종 등의 소화성 궤양을 유발하는 원인의 박테리아는 무엇인가? | Helicobacter pylori(H. pylroi)는 위염, 위궤양, 십이지장 궤양, 위선암, 위림프종 등의 소화성 궤양을 유발하는 원인의 박테리아로 알려져 있다. | |
H. pylori 박멸이 쉽지 않은 이유는 무엇인가? | 1,2) H. pylori는 나선모양의 세균으로 위 상피 세포와 점액사이에서 기생하여 위장점막 주위의 감염을 초발하며 암모니아 방출로 인해 스스로 알칼리성 보호층을 형성하여 위산을 중화시키는 능력을 가지고 있어 박멸하기 쉽지 않다. 현재 H. | |
현재 사용되는 Helicobacter pylori 치료 약제의 단점은 무엇인가? | 현재 H. pylori 감염의 치료에는 다양한 약제들이 사용되고 있으나 3) bismuth, metronidazole 및 amocxillin의 고전적 삼제요법은 높은 부작용과 낮은 순응도가 단점으로 지적되고 있다.4) 최근 omeprazole과 두 가지 항생제를 병용하는 삼제요법이 사용되고 있으며 일관된 박멸률과 우수한 순응도를 보여 일차 박멸 약제로 권장되지만 고가의 비용이 단점이 되며 박멸에 실패했을 때 재치료 약제의 선택이 문제가 된다. |
