  • 본 연구에서는 탕액에 존재하는 제랄레논의 분석을 위한 HPLC법을 확립하고 탕액조제 시 한약재로부터의 제랄레논 이행률을 조사하였다. 한약재 (괄루인, 두충, 복분자)에 제랄레논을 임의의 농도로 오염시켜 수침 및 비수침 과정을 거친 후 상압가열 ($100^{\circ}C$, 3 h)과 고압가열 ($121^{\circ}C$, 1 h)하여 탕액을 조제한 다음 탕액과 한약재 잔류물로 분리하고 immunoaffinity column으로 정제하여 분석에 사용하였다. 가열처리를 하지 않은 탕액 제조 전 원료 한약재에 대한 회수율은 괄루인 83.7-95.5%, 두충 81.9-99.7%, 복분자 79.1-82.3%로 분석에 이용이 가능한 것으로 확인되었고, 3종의 한약재 중 회수율이 가장 좋은 두충을 선택하여 탕액을 조제한 후 탕액과 한약재 잔류물에 대한 회수율 측정한 결과 탕액에서는 68.4-83.7%, 한약재 잔류물에서는 72.9-80.3%로 원재료 보다는 낮은 수준으로 확인되었다. 한약재에서 탕액으로 제랄레논의 이행률은 한약재 원재료에 제랄레논을 임의의 농도로 오염시킨 후 탕액을 조제하여 분석하였으며, 그 결과 탕액에서는 제랄레논이 검출되지 않았고, 괄루인과 복분자 잔류물에서는 수침 시료의 경우 17.04-22.99%, 비수침 시료의 경우 10.17-18.33%의 제랄레논이 검출되었다. 그리고 두충 잔류물에서는 수침 시료의 경우 10.44-17.16%, 비수침 시료의 경우 12.42-17.75%가 검출되었다. 본 연구에서는 탕액에서 제랄레논이 검출되지 않아 이행률은 낮은 것으로 판단되나 보다 탕액 조제과정 중 첨가물에 의해 이행이 일어날 수 있는 가능성은 여전히 존재하기 때문에, 제랄레논을 포함한 곰팡이독소에 안전한 한약재의 확보를 위한 지속적인 노력이 필요하다. 또한, 유통 중인 한약재를 포함하여 조제포장되어 판매되는 탕액에 대해서도 지속적인 모니터링이 필요할 것으로 판단된다.

  • Objectives : To provide the information of preservation method for herbal decoction, we evaluated the anti-inflammatory effects according to preservation temperature and period of Pyungwi-san (PWS, Ping wei-san) decoction. Methods : The anti-inflammatory activity of PWS was investigated by carrageenin-induced paw edema in SD rats. At 0 month, PWS extract was administrated 100, 300 and 1000 mg/kg/day orally for seven days prior to induction of edema. Edema was induced by subcutaneous injection of 1% carrageenin into the right hind paw. The paw volume was measured at 4 hr following carrageenin-induced paw edema in rats. At 6 and 12 months, PWS extracts according to preservation temperatures (room temperature, $4^{\circ}C$ and $-20^{\circ}C$) were administrated in rats and then carrageenin-induced paw edema volume was measured. Results : PWS showed inhibitory effect on carrageenin-induced paw edema in rats and the optimal dose was 1000 mg/kg/day at 0 month of storage. At 6 month of storage, PWS storaged at $4^{\circ}C$ and $-20^{\circ}C$ were inhibited paw edema but that storaged at room temperature was not reduced paw edema in rats. Conclusions : These results suggest that PWS decoction pouch has anti-inflammatory activities at both $4^{\circ}C$ and $-20^{\circ}C$ during 6 month storage.

  • Background: To investigate tumor inhibition effects and mechanisms of Angelica sinensis and Sophorae flavescentis ait decoction (ASSF) combined with diamine-dichloroplatinum (DDP). Materials and Methods: Bodyweight, tumor inhibition rate and q value were calculated for single ASSF or ASSF combined with DDP on H22 carcinoma xenograft KM mice. Biochemical methods for serum LDH, AST, ALT, and AKP, ELISA method for serum HIF-$1{\alpha}$, pathological assessemnt of thymus, immunohistochemistry detection of tumor tissue caspase3 and mutant p53 protein, and qRT-PCR detection of bax/ bcl-2 mRNA were applied. Results: Compared with DDP control group, the bodyweight increased in ASSF-DDP group (p<0.01). Tumor inhibition rates for DDP, ASSF, ASSF-DDP were 62.7%. 43.7% and 71.0% respectively, with a q value of 0.90. Compared with other groups, thymus of DDP control group had obvious pathological injury (p<0.01), serum LDH, AST, ALT, AKP increased significantly in DDP control group (p<0.01), while serum HIF-$1{\alpha}$ was increased in the model control group. Compared with this latter, the expression of mutant p53 protein and bcl-2 mRNA were decreased in all treatment groups (p<0.01), but there were no statistical difference between DDP control p and ASSF-DDP groups. The expression of caspase3 protein and bax mRNA was increased in all treatment groups, with statistical differences between the DDP and ASSF-DDP groups (p<0.01). Conclusions: ASSF can inhibit bodyweight decrease caused by DDP, can inhibit tumor growth synergistically with DDP mainly through increasing serum HIF-$1{\alpha}$ and pro-apoptotic molecules such as caspase 3 and bax, rather than through decreasing anti-apoptotic mutant p53 and bcl-2. ASSF can reduce DDP toxicity due to decreasing the release of LDH, AST, ALT, AKP into blood and enhancing thymus protection.

  • Objective: The purpose of this study was to investigate the effect reducing blood pressure (BP) using Xuefuzhuyu Decoction (XFZYD) in adults with essential hypertension (EH). Method: Search engine, such as PubMed, EMBASE, Cochrane library, Web of Science, J-STAGE, CiNii, CNKI, OASIS, NDSL, KISS, RISS, and DBpia, were used. The search period was from the beginning of the search engine to June 30, 2018 and there were no limits regarding languages. The selection and extraction of literatures were performed independently by two authors. Meta-analysis was done on the total effective rate (TER), Systolic BP (SBP) and Diastolic BP (DBP). Cochrane's risk of bias (ROB) was used as the methodological quality assessment scale. Results: Twenty studies were finally selected. We observed that a combination treatment using XFZYD and an antihypertensive drug (AHD) was 5.1 times more effective in lowering BP than using AHD alone on TER. The mean differences in SBP and DBP were -10.65 mmHg (95% Confidential Interval (CI) -13.55 mmHg, -7.74 mmHg, P<0.00001), -5.92 mmHg (95% CI -7.14, -4.38, P<0.00001), respectively. Conclusion: A combination treatment using XFZYD and AHD may be more effective in reducing BP than using AHD alone. Because of the poor methodological quality of the studies conducted thus far, high-quality clinical trials will be required in the future.

  • Objectives : In case of herbs decoction, the ceramic or earthware pots was recommended, but not the metals, particularly iron or aluminum, which could cause unknown chemical reactions. In Korean Medical classics, it has been known that some herbs including Caulis Lonicerae Japonicae (CL) were not recommended to boil with iron pot. This study investigates the physical changes of extracts of CL with or without iron. Methods : CL was decocted with reflux cooling extraction system to prevent evaporation and volatilization. Content of polyphenol was detected by Folin-Denis method and the levels of loganin and chlorogenic acid were evaluated by UPLC. Results : The color of extract with glass beads (GB) is yellowish brown, and the iron beads (IB) is blackish brown. Polyphenol and chlorogenic acid levels were reduced in IB extracts. Conclusions : The color of extract was change to blackish brown, and polyphenol and chlorogenic acid levels were reduced in CL extract with iron. Therefore, iron pots is not suitable for CL extraction.

  • Traditional medicines usually use combinational formula that are prepared by mixing different varieties of medicinal herbs and boiling them in water to yield a decoction. In recent years a modified method has been proposed and practiced wherein the individual herbs are boiled with water separately and later these extracts are mixed together for use. We attempted to evaluate their equivalence in terms of its polyphenol contents and DPPH radical scavenging activity. The polyphenol contents as well as the DPPH radical scavenging activities were very similar to each other.

  • Traditional medicines usually use combinational formula that is prepared by mixing different varieties of medicinal herbs and boiling them in water to yield a decoction. In recent years a modified method has been proposed and practiced wherein the individual herbs are boiled with water separately and later these extracts are mixed together for use. This practice has lead to a constant controversy concerning the chemical and biological equivalence between the preparations arriving out of these two methodologies. In this research, we attempted to study the effects of traditional and individual preparation of Ssanghwa-tang (ST) to evaluate their equivalence in terms of its antioxidant activity and polyphenol content. The study results indicate that the polyphenol contents as well as the extraction yields of these two preparations were very similar to each other.
