Objectives : We studied Effects of Hagocho(prunella vulgaris L.), Gamgook(chrysanthemum indicum L.) and Galgeun(pueraria Radix) aqua-acupuncture on the hyperlipidemic rat. methods : We investigated lowering lipid effect, oxidative capacity, concentration of TNF-${\alpha}$, IL-6, Leptin and histological consideration in hyperlipidemic rat. Forty male Sprague-Dawley rats weighing about 400g were divided into 5 groups of control, Ⅰ: Hagocho (prunella vulgaris L.)+Gamgook (chrysanthemum indicum L.) and Gokji aqua-acupuncture, Ⅱ: Hagocho(prunella vulgaris L.)+Gamgook (chrysanthemum indicum L.) and Joksamri aqua-acupuncture, Ⅲ: Hagocho(prunella vulgaris L.)+Galgeun(pueraria Radix)and Gokji aqua-acupuncture and Ⅳ: Hagocho (prunella vulgaris L.)+Galgeun(pueraria Radix) and Joksamri aqua-acupuncture. Results : Contents of plasma ${\beta}$-lipoprotein, contents of IL-6, TNF-${\alpha}$ and leptin, Plasma triglyceride and glucose, plasma total cholesterol and LDL-cholesterol, liver total cholesterol, liver triglyceride, plasma and liver TBARS, free fatty acids showed a tendency to decrease in the aqua-acupuncture groups compared to those of control group. The activities of GOT and GPT showed no significantly different in all treatment groups. Values of super oxide dismutase, glutathione peroxidase and catalase activity showed a tendency to increase in the aqua-acupuncture groups. Histological consideration of heart, kidney and liver in the aqua-acupuncture groups showed slight vasodilation and fat accumulation compared to those of normal rat. Conclusions : These results indicated that prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix aqua-acupuncture at gokji(LI11) and Joksamri(ST36) suppressed adipose tissue mass and lipid peroxidation and increased antioxidant system in hyperlipidemic rat.

Water extract from Prunella vulgaris L. (PVW) was tested for colon cancer chemopreventive activity by measuring the activities of cytochrome P450 1A1, phase Ⅱ detoxification enzyme [quinone reductase (QR) and glutathione S-transferase (GST)] and ornithine decarboxylase (ODC) and glutathione (GSH) levels in cultured human colorectal adenocarcinoma HT-29 cells. PVW significantly inhibited 7,12-dimethylbenz[a]anthracene (DMBA)-induced cytochrome P450 1A1 activity at 10 and 50 ${\mu}g/ml$. PVW induced QR activity in a dose-dependent manner over a concentration range of $1{\sim}50\;{\mu}g/ml$. GST activity was also induced with the treatment of PVW in HT-29 cells. In addition GSH levels were increased with PVW. PVW inhibited ODC activity, a key enzyme of polyamine biosynthesis, which is enhanced in tumor promotion. These results suggest that Prunella vulgaris L. has colon cancer chemopreventive activity by inhibiting cytochrome P450 1A1 and ODC activities and by increasing phase Ⅱ enzyme activity and GSH levels.

Effects of prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix on plasma lipid composition and histological consideration were investigated in hyperlipidemic rats. Concentration of plasma ${\beta},-lipoprotein$ showed a tendence to decrease in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups. However these values were showed not significantly different from control group. Concentration of plasma FFA in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups showed a lower values compared to control group and concentration of plasma FFA of prunella vulgaris L. and pueraria Radix treatment group showed a lower values than prunella vulgaris L. and chrysanthemum indicum L. treatment group. Concentration of plasma glucose and triglyceride showed a tendence to decrease in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups. However plasma glucose values showed not significantly different from control group. Plasma total cholesterol concentration showed a low and HDL-cholesterol concentration showed a high in prunella vulgaris L. and pueraria Radix treatment group. However LDL-cholesterol concentrations were not significantly different in treatment groups. Histological consideration of heart, liver and kidney in prunella vulgaris L. and pueraria Radix treatment groups showed a good features in fat accumulation condition than those of other treatment groups. However in the condition of high fat accumulation in tissues, heart, liver and kidney were showed a slight congestion and a bashed cell nucleus.

The phenolic compounds of water extracts from Prunella vulgaris were highest at 9.25 mg/g, respectively, when various extraction solvents were used. The optimum condition for extracting phenolic compounds from Prunella vulgaris was extraction in water for 18hr. The DPPH-scavenging activities of Prunella vulgaris were highest at the water extracts. The ABTS radical cation decolorization was higher than 40% in the range of 0~100% ethanol extract section. The antioxidant protection factor on the lipophilic phenolic metabolites was shown to be 1.1 PF in the water extracts from Prunella vulgaris. The TBARS was lower than the control ($0.53{\mu}M$) in all the sections. The tyrosinase inhibitory effect, which is related to skin whitening, was above 40%, and for the anti-wrinkle effect, the elastase inhibition activity was above 40% at 0.2 mg/mL. The astringent effect of the Prunella vulgaris 40% ethanol extracts was 98.1% at 1 mg/mL. As a result, it can be concluded that Prunella vulgaris has the potential to be used as a cosmetic material.

Two triterpenes 1 and 2 with antiviral activity against Herpes simplex virus type 1 in vitro were isolated from Prunella vulgaris. Each compound caused a significant reduction in viral cytopathic effect when vero cells were exposed to them for 72 hours after viral challenge. They were identified as betulinic acid (1) and $2\alpha, 3\alpha$-dihydroxyurs-12-en-28-oic acid(2) on the basis of their spectroscopic properties. The antiviral activity of them was estimated as $EC_{50}=30\;\mu$g/ml(1) and $8\;\mu$g/ml(2), respectively by plaque reduction assay.

Water extracts from Thesium chinense Tunczaninov (TCTW) and Prunella vulgaris L. (PVW) were tested for aromatase and cyclooxygenase activities. TCTW and PVW were capable of suppressing aromatase in a human placenta microsomal assay. PVW was shown to be more effective than TCTW in the suppression of aromatase activity. TCTW significantly inhibited cyclooxygenase-2 (COX-2) activity at the concentration of 0.25 (p<0.05), 0.5 (p<0.01) and 2.5 mg/ml (p<0.005). PVW also inhibited COX-2 activity in a dose-dependent manner in a concentration range of $0.05{\sim}2.5\;mg/ml$. The expression of COX-2 was inhibitied by TCTW and PVW in western blot analysis. These results suggest that TCTW and PVW may have breast cancer chemopreventive potentials by inhibiting aromatase and cyclooxygenase activities.

We examined the inhibitory activities against monoamine oxidase (MAO) of Prunella vulgaris in vitro and in vivo methods. Methanolic extract of P. vulgaris showed significantly Inhibitorγ activities on MAO-A and MAO-B that were prepared from rat brain and liver in vitro. The inhibitory activities were measured by serotonin and benzylamine as substrates, respectively. MAO-A and MAO-B activities were potently inhibited by ethylacetate extracts of P. vulgaris in vitro tests. It was observed that those activities in vivo tests have different tendency each other. MAO-A activity was increased by the oral administration of methanolic extract of P. vulgaris while MAO-B activity was decreased. Consequently, we suggest that P. vulgaris may have the effects on the inhibitory activities against MAO both in vitro and in vivo.

The whole plants of Prunella vulgaris (Labiatae) and Thesium chinense (Santalaceae) are used as Hakocho(夏枯草) in the market in Korea. In oriental medicine, these herb drugs are prescribed as a diuretic or antiinflammatory drugs. In order to investigate the efficacy of the plants, the extracts were bioassayed for antiinflammatory action. The water extracts of Prunella Herba and Thesii Herba showed remarkable anti-carrageenin effect and significant inhibition of the swellings in adjuvant arthritis in rats. However, the extracts did not show any inhibition of leucocyte emigration in CMC pouch in rats.
