This study was conducted to investigate the effect of mycelia of Lentinus edoes mushroom-cultured Lonicera japonica Thunberg (LLJ) on proliferation of the cancer cell lines (Hep3B, MCF-7 and HeLa), sarcoma 180 (S-180) and antiallergy. In an anti-cancer test using Hep3B (hepatic cancer cell), MCF-7 (breast cancer cell) and HeLa (uterine cancer cell), LLJ extract showed higher antiproliferating effect than that of LJ (Lonicera japonica Thunberg) extract. In an anti-cancer testing using Hep3B cells, LLJ extract showed growth-inhibitory effect of $85.60{\pm}4.66%$ at 3mg/rnL. In an anti-cancer testing using MCF-7 cells, LLJ and LJ extracts showed high antiproliferating effect. LLJ showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitory rates against tumor cells were 61% for LLJ, 37% for LJ. LLJ inhibited histamine release from rat peritoneal mast cells activated by compound 48/80. These results suggest that Lentinus edodes mushroom-cultured herb has an antiproliferating effect against cancer cell lines (Hep3B, MCF-7 and HeLa) and S-180 tumor, and will be beneficial in the treatment of allergic reaction.

Objective: The purpose of this study was to investigate the effect of Lonicera Japonica Thunberg (LJT) on the inflammatory factor expression associated with atherosclerosis in human umbilical vein endothelial cells (HUVECs). Methods: After treatment with LJT in HUVEC which is treated with TNF-α, we measured the expression levels of biomarkers (MCP-1, ICAM-1, VCAM-1, KLF2, and eNOS), mRNA (CCL2, ICAM1, VCAM1, KLF2, and NOS3), and the proteins (MCP-1, ICAM-1, VCAM-1, KLF2, eNOS, ERK, JNK, and p38). Results: 1. Compared to the control, LJT significantly reduced MCP-1 and VCAM-1 levels at concentrations of 100, 200, and 400 ㎍/ml and ICAM-1 expression at 200 and 400 ㎍/ml compared to the control. It increased KLF2 levels at all three concentrations, but not significantly, while eNOS expression was significantly increased at 400 ㎍/ml. 2. LJT was seen to significantly reduce the expression of CCL2, ICAM1, and VCAM1 mRNA at concentrations of 100, 200, and 400 ㎍/ml compared to the control. In contrast, significantly increased KLF2 and NOS3 mRNA levels were observed at 400 ㎍/ml and at 200 and 400 ㎍/ml, respectively. 3. Compared to the control, LJT significantly reduced the protein expression of MCP-1 and VCAM-1 at 200 and 400 ㎍/ml and of ICAM-1 at 400 ㎍/ml. In addition, it increased both KLF2 and eNOS protein levels at 200 and 400 ㎍/ml. Although LJT did not have an effect on ERK expression in comparison with the control, it significantly reduced JNK levels at 200 and 400 ㎍/ml and p38 levels at 400 ㎍/ml. Conclusions: These results suggest that LJT has an effect on the inhibition of inflammatory factor expression associated with atherosclerosis in HUVECs which could contribute to the prevention of cardiovascular and cerebrovascular diseases.

Objectives : Reactive oxygen species (ROS) are involved in a wide spectrum of diseases including chronic inflammation and cancer. In this study, we investigated the antioxidant activities and anti-inflammatory effects of the extracts from the herbal teas such as Lonicera japonica Thunberg (L. japonica), Chrysanthemum morifolium Ramat (C. morifolium), Mentha arvensis L. (M. arvensis), and P.rhizoma. Methods : Anti-oxidant activity was evaluated using DPPH radical scavenging assay and $Fe^{2+}$ chelating assay. And DNA cleavage assay was performed to evaluate an anti-oxidative effect. Anti-inflammatory effect was performed using NO generation assay and western blot in LPS-stimulated RAW264.7 cell line. Results : L. japonica scavenged DPPH radical by 9.8% at 12.5 ${\mu}g/ml$, 24.8% at 25 ${\mu}g/ml$, 34.3% at 50 ${\mu}g/ml$, 61.1% at 100 ${\mu}g/ml$ and 75.8% at 200 ${\mu}g/ml$, respectively. In addition, C. morifolium and M. arvensis removed DPPH radical by 15.6% and 10.4% at 12.5 ${\mu}g/ml$, 34.8% and 22.8% at 25 ${\mu}g/ml$, 66.9% and 43.3% at 50 ${\mu}g/ml$, 87.4% and 69.1% at 100 ${\mu}g/ml$, and 92.1% and 73.2% at 200 ${\mu}g/ml$, respectively. However, P. rhizoma did not affect on DPPH radical scavenging. The $Fe^{2+}$ chelating activity was highest in L. japonica, but lowest in P. rhizoma among the herbal teas. In addition, the extracts from L. japonica, C. morifolium and M. arvensis inhibited oxidative DNA damage via its anti-oxidant activity. In anti-inflammatory effect, the extracts from C. morifolium inhibited NO production. In addition, it suppressed the $NF-{\kappa}B$ signaling pathway in LPS-stimulated RAW 264.7 cells. Conclusions : Together, this study indicates that L. japonica, M. arvensis and C. morifolium possess the protective effect against the oxidative DNA damage. Furthermore, C. morifolium exerts an anti-inflammatory effect.

Seventy-five commercial male day-old broiler chicks were used to investigate the effects of Oxytetracycline(OTC) and Lonicera japonica Thunberg(LJT) to be active in anti-bacteria and anti-virus on the growth rate, carcass rate and various intestinal organs sizes in broiler at 3 wk of age. Five experimental diets were formulated to have similar protein and energy levels, with OTC 0.04％ as low-level antibiotics and OTC 0.34％ as high-level antibiotics and 0.5％, 1.0％, 3.0％ level of LJT. Birds were housed randomly in 15 battery cages. Birds were 3 replicates per treatment and 5 chicks per replicate. In the body gain, 0.5％ level of LJT addition grew significantly higher than the other birds. The feed intake and feed efficiency were not significantly between other birds. The addition levels in OTC and LJT did not any consistent effect on the carcass rate. However, the chest meat percentage vs carcass volume in LJT 0.5％ treatment and the leg meat percentage vs carcass volume in DTC 0.04％ addition level were significantly higher than those of birds fed other diets. The liver weight rate was significantly higher in OTC 0.04％ level. However, the 0％ and LJT levels did not exert any consistent effect on the weights of gizzard, heart, bursa of fabricius, head and spleen of broilers. The abdominal and gizzard surrounding fat content rate was higher in bird LJT 1.0％ level than birds fed other levels.

Recently, much attention has been paid to developing various kinds of fermented herbal extracts, a new type of traditional herbal medicine, in the field of Korean traditional medicine. The fermentation of medicinal herbs is intended to exert a favorable influence on digestability, bioavailavility and pharmacological activity of herbal extract in the gastrointestinal tract. It also produces a number of fermentation products that intensify the nutritional and pharmacological aspects of the medicinal herbs. In order to develop a functional beverage of alleviating the aftereffects of the previous drinks, the extracts (HP-1) of fermented herbal mixture, including Artemisia capillaris Thunb., Lonicera japonica Thunberg, and Hovenia dulcis Thunb., were prepared and the medicinal effect as a hangover cure was evaluated in ethanol-loaded rats. The enzyme activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase-2 (ALDH2) were analyzed by measuring the concentration of blood ethanol and acetaldehyde. The mRNA expression of ADH and ALDH2 was also investigated through RT-PCR analysis. In the HP-1-treated group, the concentration of blood ethanol was significantly reduced at one hour after loading of ethanol, as compared to that in the saline-treated group. The reduced ethanol was converted to acetaldehyde, which resulted in rapid increase in acetaldehyde concentration in an hour. Acetaldehyde was started to decrease at 5 hours after ethanol loading. It implies that HP-1 is highly effective to stimulate the activities of ADH and ALDH2. The HP-1 treatment also activated the mRNA expression of ADH and ALDH. This study suggests that fermented herbal extract, HP-1 can be used as a functional beverage of alleviating the alcohol-induced hangover symptoms by stimulating the activities and gene expression of hepatic alcohol metabolizing enzymes.
