An important factor in the production of organic ginseng is the control of $Alternaria$ blight and anthracnose, which mostly affect the leaves in the summer. We compared the effects of a lime-bordeaux mixture (LBM) and agricultural chemicals on the growth characteristics and ginsenoside content in 4-year-old ginseng plants when they were sprayed at 15-day intervals from mid-June to the end of September. The increases in leaf length, and survive-leaf ratio in plants sprayed with LBM were greater than the increases of the control plants, but less than those of agricultural chemicals treatment. The root weight per plant in the plants sprayed with LBM increased more distinctly than that in the control plants, while it was significantly lower than that in plants sprayed with agricultural chemicals. The root yield in plants sprayed with LBM increased by 21% compared to the root yield in the control plants, but decreased by 7% compared to that in plants sprayed with agricultural chemicals because of the decreases in leaf area and survive-leaf ratio. Spraying of LBM had a significant effect on the ginsenoside contents. The total ginsenoside content was highest in the control plants and lowest in the plants sprayed with agricultural chemicals and total ginsenoside contents was great relative to survive-leaf ratio and root weight.

Fluxapyroxad/pyraclostrobin 합제와 살균제를 9회 처리하는 처리체계의 검은별무늬병 방제효과를 조사하였다. 살균제가 처리되지 않은 무처리구의 이병엽률은 58.4%, 그리고 이병과율은 100%로 살균제 효과를 평가하기에 충분하였다. Fluxapyroxad/pyraclostrobin 합제만을 7회 처리한 처리구의 이병엽률은 평균 6.3%로 나타났고 방제가는 89.2%로 조사되었으며, 이병과율은 평균 16.7%, 방제가는 83.3%로 조사되었다. 서로 다른 계통의 살균제를 9회 처리한 검은별무늬병 처리체계의 효과를 조사한 결과, 이병엽률은 5.0%, 이병과율은 13.3%로, 각각의 방제가가 91.4%와 86.7%로 조사되었다. Fluxapyroxad/pyraclostrobin 합제 처리구와 비교해 보았을 때, 살균제를 9회 처리하는 처리체계에서 잎과 과실 모두에서 검은별무늬병의 발병률이 다소 낮게 나타났으나, 통계적인 유의성은 보이지 않았다. 이러한 결과는 수출전업농가에서 사용 가능한 새로운 살균제의 선발을 통한 효율적인 방제가 이루어 진다면 검은별무늬병 방제체계를 확립하는데 도움을 줄 수 있을 것으로 생각한다.

Ginsenosides are one of the most well-known traditional herbal medicines frequently used for the treatment of cardiovascular symptoms in korea. The anti-ischemic effects of the mixture of ginsenoside $Rg_3$, and CK on ischemia-induced isolated rat heart were investigated through analyses of changes in hemodynamics ; blood pressure, aortic flow, coronary flow, and cardiac output. The subjects in this study were divided into four groups: normal control, the mixture of ginsenoside $Rg_3$ and CK, an ischemia-induced group without any treatment, and an ischemia-induced group treated with the mixture of ginsenoside $Rg_3$ and CK. There were no significant differences in perfusion pressure, aortic flow, coronary flow and cardiac output between them before ischemia was induced. The supply of oxygen and buffer was stopped for five minutes to induce ischemia in isolated rat hearts, and the mixture of ginsenoside $Rg_3$ and CK was administered during ischemia induction. Treatments of the mixture of ginsenoside $Rg_3$ and CK significantly prevented decreases in perfusion pressure, aortic flow, coronary flow, and cardiac output under ischemic conditions. In addition, hemodynamics (except heart rate) of the group treated with the mixture of ginsenoside $Rg_3$ and CK significantly recovered 60 minutes after reperfusion compared to the control group (mixture+ischemia vs ischemia - average perfusion pressure: 74.4${\pm}$2.97% vs. 85.1${\pm}$3.01%, average aortic flow volume: 49.11${\pm}$2.72% vs. 59.97${\pm}$2.93%, average coronary flow volume: 58.50${\pm}$2.81% vs. 72.72${\pm}$2.99%, and average cardiac output: 52.47${\pm}$2.78% vs. 63.11${\pm}$2.76%, p<0.01, respectively). These results suggest that treatment of the mixture of ginsenoside $Rg_3$ and CK has distinct anti-ischemic effects in ex vivo model of ischemia-induced rat heart.

Objectives : This study was conducted to investigate the effect of HTE001, a multi-herbal mixture consisting of 10 herbs, Cornus Frutus, Schizandrae Fructus, Rubi Fructus, Cnidi Fructus, Acanthopanacis senticosi Radix, Cinnamomi Cortex, Eucommiae Cortex, Allii Bulbus, Rehmanniae Radix and Ginseng Radix, on electrostimulation-induced penile erection in rats. Methods : Intracavernous pressure (ICP) and mean arterial blood pressure (MAP) were simultaneously monitored through electric stimulation of the cavernous nerve after the oral administration of HTE001 (30, 100, 300 mg/kg) in normal rats. Statistical analysis was performed on maximal intracavernous pressure (ICP), maximal intracavernous pressure/mean arterial blood pressure (ICP/MAP) ratio, and the area under the curve (AUC) of ICP/MAP ratio. Results : Oral administration of HTE001 300 mg/kg caused the ICP to increase in a frequency-dependent manner. And HTE001 300 mg/kg treatment group showed the highest value in the ICP/MAP ratio and the AUC value of the ICP/MAP ratio compared to the control group at 2 Hz, 6 Hz and 10 Hz, respectively without an effect on the mean arterial blood pressure under the same stimulation of the cavernous nerve. Conclusions : These results show that HTE001 improve penile erection and prolong the decay period in normal rats without affecting mean arterial blood pressure, and suggest that HTE001 could be a good therapeutic candidate to treat erectile dysfunction.

Rumex crispus (RC) or Cordyceps militaris (CM) has been used traditionally to treat various diseases and has been also consumed as a functional food made by humanitas medicine concept. We prepared a new herbal mixture, AST2017-01 which is mainly composed of processed (Beopje)-RC (P-RC) and -CM (P-CM). This study aims to validate marker compounds (chrysophanol and cordycepin) in P-RC and P-CM and water extracted-RC and -CM using liquid chromatography-tandem mass spectrometry. In addition, we analyzed contents of chrysophanol and cordycepin in AST2017-01. The linarites of chrysophanol and cordycepin were obtained in calibration curve with a coefficient of correlation of 0.999. The results showed that the concentrations of chrysophanol and cordycepin in P-RC and P-CM were almost 1.70 and 1.23 fold higher than that in RC and CM, respectively. Furthermore, contents of chrysophanol and cordycepin in the AST2017-01 are approximately 0.13% and 0.028%, respectively. In conclusion, these results indicate that chrysophanol and cordycepin were validated as marker compounds in the AST2017-01.
