  • 모델약물로 acetaminophen을 사용하여 우리나라에 자원이 풍부한 키토산을 약물전달체계에 응용하려고 시도하였다. 키토산 분산체는 단순혼합물과는 다른 형태였으며 용출지연을 나타냈다. 요출거동의 차이는 약물의 물성보다는 polycation인 키토산의 막형성능과 pH에 좌우되었으며 polyanion인 polyacrvlate을 첨가한경우는 막형성능은 저조했으나 겔형성이 뛰어나 키토산 단독보다 용출이 지연되었다 키토산의 아미노기와 shiff's base를 형성하는 수종의 aldellyde는 키토산분산막과 chitosan-polyacrylate분산막을 강하게 경화시켜 용출을 저하시켰다. 특히 가교제의 농도와 양, 막과 반응하는 시간과 방법에 따라 막의 물리적특성 및 용출거동이 큰영향을 받았다.

  • Pain management is an important part of dental practice, and dentists frequently prescribe analgesics to improve clinical outcomes. Dentists should be aware of the pharmacological characteristics of the analgesics commonly used in dentistry and should choose appropriate analgesics to treat and prevent pain associated with inflammation or surgery. In this article, we review the potential benefits and risks of the analgesics frequently used in dental practice and provide a stepwise approach for pain management.

  • Some studies reported physicochemical factors of drugs affecting solubility and dissolution rate. However, few have been reported about pharmaceutical application of crystal forms (habits). Therefore, using acetylsalicylic acid and phenacetin as model substances, we monitored the effects of crystal forms on the dissolution rates.

  • Herbal medicines are increasingly being utilized to treat a wide variety of disease processes. We previously reported that aqueous extract from the roots of Platycodon grandiflorum A. DC (Campanulaceae), Changkil (CK). had hepatoprotective effects against acetaminophen induced liver injury. In the present study, we assayed the preventive and therapeutic effects of CK on experimental hepatic fibrosis induced by dimethylnitrosamine (DMN) in rats. (omitted)

  • Mucosal administration of drug or therapeutic gene is emerging as a new route of delivery for systemic and local therapeutics. Previously. in situ gelling system has been applied to chemical drug such as acetaminophen. insulin. prostaglandin E1. and clotrimazole. Plasmid DNA has not been delivered in form of in situ gelling vehicles. To improve the intranasal absorption of plasmid DNA. we designed delivery systems composed of provide of in 냐셔 gelling and mucoadhesive polymers. (omitted)

  • Uniform microcapsules containing ionic model drugs were prepared by controlling various conditions of emulsification procedure using a lab-scale membrane emulsification system with a SPG (Shirasu porous glass) tubular membrane. We observed the effects of various emulsification parameters [concentration and molecular weight of polycaprolatone (PCL) polymer, transmembrane pressure and emulsifier concentration in disperse phase and continuous phase, stirring speed] on the mean size and size ditribution of microcapsules containing lidocaine hydrochloride (cationic drug), sodium salicylate (nonionic drug) and 4-acetaminophen (anionic drug) used as a model drugs. Also, release characteristics of a model drugs from PCL microcapsules were investigated. Controlling membrane emulsification parameters, uniform PCL microcapsules with about $5\;{\mu}m$ of the mean size were finally prepared. The release rate and the burst effect of microcapsules were decreased in condition of the acidic solution, but it was increased in condition of the base solution.

  • Objectives: The objective of this research is to develop new animal-experimental model for Sasang Constitutional Medicine, especially for partial Taeyangin(one of four constitution which has good pulmonary function and poor hepatic function) by AAP intraperitoneal injection, and to estimate from the viewpoint of obesity and lipid metabolism. Methods: The C57bl/6J mice was divided into 4 groups ; Normal group, AAP group, High-Fat-Diet(HFD) group, and HFD+AAP group. 200mg AAP was injected intraperitoneally to the AAP group twice a week for six weeks, and HFD group was fed with 60%-High-fat Diet for six weeks. HFD+AAP group got both AAP injection and 60%-High-fat Diet at the same time for the same period. In this period, We measured the weight and Food Efficiency Ratio(FER, %) once a week. After six weeks, We conducted the blood chemical test from the groups, and extracted the fat tissue to measure weight. Results & conclusion: In the liver function test, two AAP groups had higher AST and ALP, and normal LDH. The blood level of creatinine from all groups were normal. The rate in weight was lesser by 7.8% in HFD+AAP group, and had lesser FER than HFD group. Also They had lesser Total cholesterol and LDL cholesterol, and had more HDL cholesterol than HFD group. HFD+AAP group hadmore glucose in serum and lesser Insulin-like Growth Factor 1(IGF-1) than HFD group.
