The aim of this study was to evaluate the effects of Jowiseungcheongtang compared with St. John's wort in the chronic mild stress(CMS) animal model of depression. Wistar rats were used for this study. The subjects were divided into 4 groups (Naive group: without CMS procedure, CMS-vehicle: water was administered during CMS procedure, CMS-Jowiseungcheongtang: Jowiseungcheongtang was administered after 5 weeks of CMS procedure, CMS-St. John's wort: St. John's wort was administered after 5 weeks of CMS procedure) During 9 weeks of CMS procedure, The change of the consumption of sucrose and the changes of weights were measured. After CMS procedure, Morris water maze test, open field test, elevated plus maze test and Western blotting were measured. The results were as follows. 1. The consumption of sucrose solution was significantly reversed in Jowiseungcheongtang group and relatively reversed in St. John's Wort group at 7 week. 2. In open field test, Neither Jowiseungcheongtang nor St. John's wort group showed statistically significant change of exploratory activity. In EPM test, St. John's Wort group showed significant decrease of total arm entry in comparison with Naive group. And Jowiseungcheongtang group was showed no significant change. 3. In Morris water maze test, St. John's Wort group showed significant increase in escape latency of the last Morris water maze trial. And in water maze probe test, there was no significant change. 4. St. John's Wort group showed relative increase in LP1 division of 5HT1A receptor compared with Naive group. Both St. John's Wort and Jowiseungcheongtang group showed relative increase in P2 division of GluRl compared with Naive group. These results suggest that Jowiseungcheongtang is as effective as St. John's Wort in the treatment of depression.

Objective : This study was designed to assess the protective effects of Bambusae caulis and St. John's Wort on the animal model of depression, induced by chronic mild stress(CMS) Method : Male Wistar rats were used for this experiment. The subjects were divided into 4 groups ( 1. CMS-drugs: Bambusae caulis administered during CMS treatment, 2. CMS-drugs: St. John's Wort administered during CMS treatment, 3. CMS-vehicle: Water administered during CMS treatment, 4. normal control group without CMS treatment ). After 3 weeks of CMS treatment, they were executed open field test and weight, sucrose intake were measured. Result : 1. CMS Bambusae caulis group showed significant difference of locomotor activities and marginal difference of start latency in comparison with other groups in open field test. 2. There was no change of weights between CMS Bambusae caulis, St. John's Wort groups and CMS control group. 3. CMS St. John's Wort group showed upper level of sucrose intake than CMS Bambusae caulis group and CMS control group. Conclusion : These results suggest that Bambusae caulis may have protective antidepressant effects in CMS model rats. And these effects could be explained by the elevated locomotor activities in open field test.

St. John's wort를 성인병 예방을 위한 기능성 식품소재로 이용하기 위하여 추출물의 생리활성효과를 조사하였다. 추출물의 phenol 함량은 열수추출물이 $237.4{\pm}13.2\;{\mu}g/ml$였으며, 알콜추출물은 $246.0{\pm}10.5\;{\mu}g/ml$로 알콜추출물의 phenol 함량이 다소 높게 나타났다. 추출물의 항산화효과는 DPPH가 열수추출물과 알콜추출물이 각각 95.02%, 95.24%로 높게 나타났고, antioxidant protection factor는 알콜추출군이 PF 1.78정도로 지용성물질에 대한 항산화력도 높은 것으로 확인되었으나 열수추출물의 경우 지용성 물질에 대한 항산화력이 거의 없었다. Helicobacter pylori에 대한 추출물의 항균활성은 열수추출물의 경우 clear zone이 나타나지 않았으며 알콜추출물의 경우 $100\;{\mu}g/ml$과 $150\;{\mu}g/ml$의 농도에서 각각 11 mm와 13 mm의 clear zone이 관찰되어 저해활성이 높은 것으로 판단되었다. Angiotensin converting enzyme 저해효과는 열수추출군에서만 19.15%의 angiotensin converting enzyme에 대한 저해력을 나타내어 고혈압의 예방 효과는 비교적 낮았다. Xanthin oxidase에 대한 억제효과는 열수추출물이 84.79%, 알콜추출물이 100%의 완벽한 저해효과를 나타내어 xanthin oxidase에 대한 높은 저해를 관찰할 수 있었다. 이러한 결과로 St. John's wort는 Helicobacter pylori에 대한 항균제, 항산화제 및 anti-gout 소재로의 개발이 기대되었다.

In recent years, the combined use of Herbal medicines and Western drugs has been increasing. Though certain problems may occur when both types of medicines are taken together, they havenot been adequately analyzed. It was reported that anticoagulation was enhanced in addition tobleeding when patients took long-term warfarin therapy in combination with Salvia miltiorrhiza(danshen), and laxative herbs accelerate intestinal transit and interfere with the absorption. Herbal constituents, curcumin, ginsenosides, piperine, catechins and silymarin were found to beinhibitors of P-glycoprotein. St John's wort induces the intestinal expression of P-glycoprotein. Anthraquinone, quercetin and coumarins were found to be a potent inhibitor of P-450. Glycyrrhizin or liquorice extracts, Garlic and St John's wort are a potent inducer of CYP3A4. This review provides a critical overview of interactions between herbal medicines and other drugs. Hence, it is necessary to study the pharmacodynamic and pharmacokinetic interactions of many herbal medicines between western drugs.

2003년 6, 8월에 지리산과 전남 담양군의 병풍산에서 자생하는 고추나물과 물레나물을 채집하여 TLC 분석을 하고, TLC-densitometry를 이용해 정량한 결과, 물레나물에서는 hypericin이 확인되지 않은 반면, 고추나물의 꽃봉오리와 잎에서는 다량의 hyepricin이 확인되었다. 그리고 지리산에 자생하는 고추나물보다 병풍산 고추나물의 hypericin함량이 더 높게 나타났고, 고도가 낮을수록 hypericin 함량이 높은 것으로 나타났다. 채집 시기별로 비교했을 때, 병풍산은 6월보다 7월에서 hypericin함량이 높게 나타났고, 지리산에서는 7월에 가장 진하게 보였다. St. John's wort와 고추나물을 비교하였을 때, 2.22 $mg/{\ell}$ hypericin을 함유한 St. John's wort 보다 3.2 $mg/{\ell}$의 함량을 보이는 병풍산 고추나물에서 hypericin함량이 더 높은 것으로 확인되었다.

BACKGROUND/OBJECTIVES: This study was conducted to assess the potential of St. John's Wort (Hypericum perforatum) to prevent obesity and abnormalities in lipid metabolism induced by ovariectomy in a rat model without stimulatory activity on uterus. MATERIALS/METHODS: Ovariectomized (OVX) rats were treated for 6 weeks with 70% ethanol extracts of Hypericum perforatum [HPEs: whole plant (WHPE) and flower and leaves (FLHPE)], ${\beta}$-estradiol-3-benzoate at a dose of $50{\mu}g/kg/day$ (E2) or vehicle (distilled water). RESULTS: As expected, OVX increased body weight gain and adiposity and showed higher food efficacy ratio. OVX also increased the serum cholesterol as well as insulin resistance, while reducing uterus weight and uterine epithelial proliferation rate. HPEs (WHPE and FLHPE) showed estrogen-like effect on body weight gain, adipose tissue weight and food efficacy ratio in OVX rats. HPEs prevented hypercholesterolemia induced by OVX more effectively than E2. E2 increased uterus weight and epithelial proliferation rate in OVX rats, while HPEs maintained them at the level of the sham-operated animals. CONCLUSIONS: Our finding demonstrates that HPEs can be considered as an effective agent to prevent OVX-induced obesity without stimulatory activity on uterus.

BACKGROUND/OBJECFTIVES: The effect of St. John's Wort extract (SJW) on MG-63 cell proliferation and trabecular bone loss induced by ovariectomy was examined. MATERIALS/METHODS: Proliferation, expression of estrogen receptor (ER) ${\alpha}$ and ER ${\beta}$, and gene expressions of osteoprotegerin (OPG), osteocalcin (OC) and alkaline phosphatase (ALP) were examined in MG-63 cells treated with or without SJW. Ovariectomized rats were treated with SJW at the dose of 100 or 200 mg/kg/day, ${\beta}$-estradiol-3-benzoate (E2), or vehicle only (OVX-C), and sham operated rats were treated with vehicle only (Sham-C). Serum ALP and C-telopeptide (CTX), and femoral trabecular bone loss were examined. RESULTS: SJW increased MG-63 cell proliferation and expression of ER ${\alpha}$ and ER ${\beta}$, and positive effect was shown on gene expressions of ALP, OC and OPG. SJW also showed estrogen like effect on bone associated with slowing down in trabecular bone loss. Histopathology by H&E showed rats treated with SJW displayed denser structure in metaphyseal region of distal femur compared with rats in OVX-C. SJW was shown to reduce serum CTX in OVX rats. CONCLUSION: The present study provides new insight in preventing estrogen deficiency induced bone loss of SJW and possibility for its application in bone health supplement.

하이퍼리신(Hypericin, HyH)은 예로부터 성 요한의 풀(St. John's Wort)로 널리 알려져 있는 서양고추나물(Hypericum perforatum)에서 추출되는 약리성분이다. 서양고추나물은 국내에서는 자생하지 않으나 같은 속의 고추나물(H. erectum) 등이 이속에 속하며 우리나라에 자생한다 . 고추나물을 조직배양으로 RNA를 추출하고 cDNA를 합성한 후 Hyp 유전자를 추출하여 서열화한 결과, 전체 크기는 732 bp로 나타났으며 서양고추나물의 HyH-1과 거의 99.8% 서열 일치를 나타내었다. 이 서열의 152개 아미노산 역시 서양고추나물의 항산화효소와 98% 일치하였으며 자작나무와 능금속 식물에서 유발되는 알레르기 유발유전자와 약 60% 일치를 나타내었다. 본 연구 결과 우울증치료제로 사용되는 하이퍼리신 추출에 우리나라 자생종인 고추나물이 이용될 수 있을 것으로 사료된다.
