Combination of two or more preservatives are commonly used in cosmetic creams to prevent alteration and degradation of the product formulation. but preservatives are one of the main causes of allergic contact dermatitis from the use of cosmetics. (omitted)

With the Sunshine policy, exchange of materials and cultures inter Koreas has been broadened and expectancy of reunification is getting higher. Especially, medical supplies and medicines are one of the biggest parts in the exchange goods. So, preparing an unified official drug standard preparing new medical administration system is required. We compared the Korean pharmacopoeia with North Korean Pharmacopoeia. Two pharmacopoeias have been developed in different direction and have many differences in the nomenclature and format. In this study, we compared general notices, general rules for preparations and crude drugs, monographs, general tests, processes and apparatus.

Drugs are often taken together with meals and there are numerous opportunity for food-drug interaction to occure. Food-drug interactions and their clinical consequences are very complex indeed. The composition of the meal, and the volume of fluid that is ingested often are decisive factors in food-drug interactions. Various formulations of a specific drug may behave differently. Solutions and suspensions seem to be less susceptible and enteric-coated preparations are more susceptible, to food interactions than are other dosage forms but exceptions to this rule do exist. Furthermore, generic and environmental factors, disease and other drugs cause considerable inter- and intraindividual variation in food-drug interactions. Also, eating habits are dissimilar in different parts of the world, and diets often vary greatly from day to day. The taking of drugs together with meals offers some obvious benefits. It may help to reduce gastrointestinal irritation and compliance is improved. On the other hand, in some cases food interferes seriously with drug absorption. The purpose of this review is to clarify the complexity of food-drug interactions, and to discuss interactions that may be of clinical importance.

An analytical method was developed for the determination of sedaxane in agricultural products using liquid chromatograph-tandem mass spectrometry (LC-MS/MS). The samples were extracted with acetonitrile and partitioned with dichloromethane to remove the interference, and then purified by using silica SPE cartridges to clean up. The analytes were quantified and confirmed by using LC-MS/MS in positive ion mode using multiple reaction monitoring (MRM). The matrix-matched calibration curves were linear over the calibration ranges ($0.001-0.25{\mu}g/mL$) into a blank extract with $r^2$>0.99. For validation, recovery tests were carried out at three different concentration levels (LOQ, 10LOQ, and 50LOQ, n=5) with five replicates performed at each level. The recoveries were ranged between 74.5 to 100.8% with relative standard deviations (RSDs) of less than 12.1% for all analytes. All values were consistent with the criteria ranges requested in the Codex guidelines (CAC/GL 40, 2003) and Food Safety Evaluation Department guidelines (2016). The proposed analytical method was accurate, effective and sensitive for sedaxane determination in agricultural commodities.
