  • Objectives Banha-sasim-tang (BST), which consists of seven different herbs, is one of the most popular herbal formulae for treating gastrointestinal disorders in Eastern Asia. The commonly used herbal medicine is often co-administered with other therapeutic drugs, which raises the possibility of herb-drug interactions and may modify the clinical safety profile of therapeutic drugs. Methods We investigated the potential herb-drug interactions between BST extract and midazolam (MDZ) in mice. The area under the plasma concentration-time curve (AUC) of MDZ and 1'-hydroxymidazolam (1'-OH-MDZ) was evaluated for both oral and intraperitoneal administration of MDZ, following oral administration of BST (0.5 and 1 g/kg). Results It was found that the AUC of MDZ and 1'-OH-MDZ was lower in case of oral administration of MDZ. Administration of BST extract was not associated with hepatic cytochrome P450 activity. BST extract induced a strong reduction in pH and it has been reported that oral mucosal absorption of MDZ is lower at low pH. The decreased absorption rate of MDZ might be caused by the ingredients of BST and may not be related to other factors such as increased excretion of MDZ by P-glycoprotein. Conclusions The altered pharmacokinetics of midazolam caused by co-administration with BST in vivo could be attributed to a decrease in pH and subsequent reduction of MDZ absorption rate.

  • As the projects of this institute, 205 species of plants which are used currently as herb drugs in Korea were screened on the presence of alkaloids, phenolic compounds, flavonoids, chalcones, lactones, glycosides, carbohydrates, terpenoids, steroids, proteins, polypeptides, saponins, and organic acids$^{1-4)}$, and the most reliable presence of alkaloids was detected by paper chromatography$^{5-8)}$. In this paper, presence of alkaloids detected by thin layer chromatography is added after screening of 40 species.

  • Sixteen kinds of Chinese herb drugs using in digestive system have screened for antibacterial activity. It was revealed that all of the herb drug extracts showed antibacterial activity in one or more strains of microbials selected in this experiments. It is noteworthy that Aconitum trilobum showed inhibition of Klebsiella pneumoniae.

  • Korean ginseng (Panax ginseng Meyer) is a traditional herb used across the world to treat various diseases. Although, red ginseng is this herb's most famous product and has demonstrated diverse pharmacological activities, white ginseng (WG) is another ginseng product that is made fresh and individually regulated in Eastern Asia. Red and white ginseng show different characteristics due to distinct processing steps despite originating from the same plant, and the drug interactions induced by WG have not been well documented. Selegiline is a selective monoamine oxidase (MAO) inhibitor used as an antidyskinetic and antiparkinsonian agent. Here we developed a quantification method for selegiline in mouse plasma using a C8 stationary phase in triple quadrupole-mass spectrometry (LC-MS/MS) with multiple reaction monitoring (MRM). The validated LC-MS/MS method was successfully applied to determine the potential interaction with WG extract (0.1 g/kg/day) pre-administered for 4 weeks. The $AUC_{0-240min}$ of selegiline was altered due to a decrease in the absorption of selegiline with repeated administration of WG extract.

  • Objectives : The purpose of this study is to investigate interaction and safety in administering herb-medicine with warfarin. Methods : For this study, we selected 19 patients who have been taking warfarin, from the ones that have been transferred from western hospital to oriental hospital. During their stay in the oriental hospital, we gave herb-medicine in addition to warfarin. Then we gathered informations and data on sex, age, main indications, and International Normalized Ratio(INR) values of selected patients through Electronic Medical Records(EMR) of Dong-Guk university hospital. Accordingly, we compiled all of the above data for a period of 10 days prior and 10 days post admission(western hospital period and oriental hospital period, respectively). Results and Conclusions : The statistical analysis of the data have revealed that there was no significant change of INR values after giving herb-medicine with warfarin(p=0.586). The result shows that administration of herb-medicine with warfarin is safe and has little drug interaction. However, this study was carried out on small sample size and the interaction with other drugs and various kinds of herb-medicine was not considered. Although we attained a restrictive result from this study, we are able to suggest the safety about co-administration of herb-medicine and warfarin.

  • The Background and Purpose : Many herb-medicines are frequently used in China but they are not in Korea. It is required to prove them worthy to introduce into Korea and to find substitutes for them. The Objective and Methods : During stay in China as a Professor extraordinary, I investigated applications of Chinese modicines, books and theses. The Results and Conclusions : 1. In China the cheap herb-medicines are chosen preferentially and the classic rules of oriental medicine are truly observed. 2. in China it is impossible to prove virtue of ready made herb-medicines because constituents are not opened. 3. Commonly used herb-medicines are drug of clean away heat(淸熱藥) which are antinflammatories or anti-toxins. 4. Antitumorigenic effects was frequently reported but they don't get complete agreement also in China. 5. Herb-medicines which are frequently used in China but not in Korea have no significant differences from commonly used herb-medicines in Korea.

  • The essential oils from 73 aromatic herb drugs entered on Korean official formularies were tested for antibioticresistance inhibitory effect. When the oils were combined with ampicillin (Am) or amoxicillin (Amx) they showed significant inhibitory effects on the growth of multi-drug resistant Staphylococcus aureus SA2 in considerably low concentration. The most effective combination were oils from Magnoliae Flos or Piperis longi Fructus ($25{\mu}g/mL$)-Am or Amx ($4{\mu}g/mL$).

  • Thirty six essential oils from herb drugs entered in Korean official formulary, which are frequently used in oriental region, were tested for antibiotic resistance inhibition. When the oils were combined with ampicillin (Am) or amoxicillin (Amx) they showed significant inhibitory effects on the growth of multi-drug resistant Staphylococcus aureus SA2 in considerably low concentration. The most effective combinations were oils from Acanthopanacis Cortex ($0.49{\mu}g/mL$) with Am and Cnidii Rhizoma and Lonicerae Flos (2.77 and $2.79{\mu}g/mL$, respectively) with Amx as shown in minimum resistance inhibitory concentrations.
