  • The effects of herbal medicine on type 2 diabetic animal model were investigated. Herbal medicine were composed with the addition of Coicis Semen into Okchun-san (OCS). Commelinae Herba into Gangsim-tang (GST). Scrophulariae Radix into Hyunsamsunki-san (HSK). and Erythrinae Cortex into Yukmijihuang-hwan (YMH). We evaluated anti-hyperglycemic and body weight reduction activity in diabetic db/db mice. The experimental animals were divided into six groups. as control group and five sample groups. Each 200mg/kg/day of OCS, GST, HSK and YMH was administered with orally for 14days long. 5mg/kg/day of acarbose was administered with orally for 14days long. On day 14, OCS-treated db/db mice had significantly lower fasting blood glucose levels compared to control group(296±25.9 versus 593±16.4mg/dl. p<0.001). During the 2 h intraperitoneal glucose tolerance test (IPGTT), all the sample groups were improved compared to control group but insignificantly. After 14days of extract treatment. body weight in control. YMH and acarbose groups were increased. but OCS. GST and HSK groups reduced. However. it did not significantly lower hemoglobin Alc(HbAlc) in blood of db/db mice. These result suggest that OCS could be effective on insulin-independent type 2 diabetes.

  • To evaluate effect of CRSST on inhibiting the occurrence of arthritis, we performed the experiments including production of inflammatory cytokine and immunoglobin in collagen induced arthritis model. The results were obtained as follows. CRSST extract shows any cytotoxicity effect on mouse lung fibroblast cells at dose of 400 ㎍/㎖. CRSST group shows inhibitory effect on arthritis incidence than control group for six weeks. Arthritis index of CRSST group reduces from 4 weeks (75±17.4%) to 6 weeks (33.3±10.0%) compared with control group. In CRSST group, production of cytokines which shows suppressive effect on inflammation (IL-4, IL-10 ) are increased and which promotes inflammation (TNF-α, INF-γ) are decreased in blood. In CRSST group, production of immunogloblin (IgG2b, IgG3 and IgM) is reduced compared with control group, and rate of CD4+ and CD3+ T cell is lower in joint and higher in lymph node compared with control group. From above results it could be accepted that CRSST shows anti-arthritis effect via immune system especially through the controlling the inflammatory cytokines and immunoglobins. CRSST could be usefully applied for the prevention and treatment of RA. And also is expected to be clinically helpful on the treatment of RA through modification.

  • The genetic effects of restraint stress challenge on HPA axis and the therapeutic effect of Boshimgeonbi-tang on the stress were studied with cDNA microarray analyses, RT-PCR on hypothalamus using an immobilization-stress mice as an animal model. Male CD-1 mice were restrained in a tightly fitted and ventilated vinyl holder for 2hrs once a day, and this challenge was repeated for seven· consecutive days. In the change of body weight it showed that the Boshimgeonbi-tang is effected recovery on weight loss caused by the immobilization-stress. Seven days later, total RNA was extracted from the organs of the mouse, body-labeled with $CyDye^{TM}$ fluorescence dyes and then hybridized to CDNA microarray chip. Scanning and analyzing the array slides were carried out using GenePix4000 series scanner and GenePix $Pro^{TM}$ analyzing program, respectively. The expression profiles of 109 genes out of 6000 genes on the chip were significantly modulated in hypothalamus by the immobilization stress. Energy metabolism-, lipid metabolism-, apoptosis-, stress protein, transcriptional factor, and signal transduction-related genes were transcriptionally activated whereas DNA repair-, protein biosysthesis-, and structure integrity-related genes were down-regulated in hypothalamus. The 58 genes were up-regulated by the mRNA expression folds of 1.5 to 7.9. and the 51 genes were down-regulated by 1.5 - 5.5 fold. The 11 genes among them were selected to confirm the expression profiles by RT-PCR. The mRNA expression levels of Tnfrsf1a (apoptosis), Calm2 (cell cycle), Bag3 (apoptosis), Ogg1 (DNA repair), Aatk (apoptosis), Dffa (apoptosis), Fkbp5 (protein folding) were restored to the normal one by the treatment of Boshimgeonbi-tang.

  • This experiment was designed to investigate the effect of Farfarae Flos(FF) on immune cells and cytokines in murine asthma model. C57BL/6 mice were sensitized and challenged with OVA(ovalbumin) for 9 weeks(3 times a week). The experimental group was treated with Farfarae Flos extract(FF) for the later 6 weeks(5 times a week). We measured IL-4, 1L-5, 1L-13, IgE, IFN-${\gamma}$ in bronchoalveolar lavage fluid of ovalbumin induced asthmatic mouse and observed murine lung tissue. The results were obtained as follows: Total leukocytes and eosinophils in BALF of the mice group treated with FF decreased significantly compared with those of control group. The concentration of IL-4, IL-5, IL-13, IgE in BALF of the mice group treated with FF decreased significantly compared with those of control group. The concentration of IFN-${\gamma}$ in BALF of the mice group treated with FF increased significantly compared with that of control group. According to the above results, it is suggested that FF extract might be useful applied for prevention and treatment of allergic asthma.

  • We investigated the effects of electroacupuncture (EA) on the expression of cyclooxygenase in the spinal cord of acute inflammatory pain model. Inflammation was induced by an intraplantar injection of 1% carrageenan into the right hind paw of Sprague-Dawley. Bilateral 2 Hz EA stimulation with 0.5 mA, 1 mA and 3 mA were delivered at those acupoints corresponding to Zusanli and Sanyinjiao in man via the needles in carrageenan-injected rats. Three hours after carrageenan injection, effects of EA on cyclooxygenase (COX) expression were observed in the dorsal horn of the spinal cord using immunohistochemical method. The immunoreaction of COX-1 tended to increase in the superficial laminae and the neck of the dorsal horn as compared with normal. The COX-2 immunoreaction in the carrageenan-injected rat was also significantly increased in the all regions of the dorsal horn as compared with normal one. However, COX-1 immunoreaction in carrageenan-injected rat were decreased in the superficial laminae and neck of the dorsal horn by low intensity of EA stimulation. Except high intensity of EA stimulation in the superficial laminae, COX-2 expression was attenuated in all regions of the dorsal horn by all types of EA treatment. It is concluded that EA treatment may attenuate inflammatory pain in carrageenan-injected rat through modulating expression of COX-2 in the dorsal horn of the spinal cord.

  • The DNA topoismerase I inhibitor ${\beta}-lapachone$, the product of a lapacho tree (Tabebuia avellanedae) from South America, activates a novel apoptotic response in a number of cell lines. In the present report, we investigated the effects of ${\beta}-lapachone$ on the growth of human lung in human non-small-cell-lung-cancer A549 cells. Upon treatment with ${\beta}-lapachone$, a concentration-dependent inhibition of cell viability and cell proliferation was observed as measured by hemocytometer counts and MTT assay. The ${\beta}-lapachone-treated$ cells developed many of the hallmark features of apoptosis, including membrane shrinking, condensation of chromatin and DNA fragmentation. These apoptotic effects of ${\beta}-lapachone$ in A549 cells were associated with a marked induction of pro-apoptotic Bax expression, however the levels of anti-apoptotic Bcl-2 expression were decreased in a dose-dependent manner. Accordingly, elevated amount of cyclin-dependent kinase inhibitor p21 expression accompanied by up-regulation of tumor suppressor p53 was observed. By RT-PCR analyses, decrease in gene expression level of telomerase reverse transcriptase and telomeric repeat binding factor were also observed. Thus, these findings suggest that ${\beta}-lapachone$ may be a potential anti-cancer therapeutics for the control of human lung cancer cell model.

  • The study was conducted to investigate per oral (PO) effects of Black raspberry wine on testosterone levels in Sprague-Dawley rats oral administrated with Methoxychlor in order to establish the experimental clinical model for evaluating the influences on the sexual hormones of SD-Rat administrated with Methoxychlor(MET), it was dissolved in acetone and olive oil (1:19), which was administrated orally at doses of 200mg/kg body weight/ day for 7days. Black raspberry wine of 13% alcohol concentration, was prepared from ripen fruits of Rubus coreanus fermented with Saccharomyces cervisiae. PO administration of Black raspberry wine for 15 week produced dramatic increases of serum testosterone levels. Increase in the testosterone level was observed, using gamma counter with 125I testosterone, starting from 1 week post administration. Maximum increase in testosterone level was observed at 4 week post administration, 5.18${\pm}$0.76ng/mL, which was 10.1 times higher than before and at 15 weeks post administration it was recorded as 1.67${\pm}$0.19ng/mL indicating Black raspberry wine as an effective phyto-testosteronic beverage of the future.

  • Sopung-san(SPS; prescription No. DO27), a herbal medicine prescribed by oriental hospital of Daegu fanny University, has been used as cure for pruritus and psoriasis. To evaluate anti-inflammatory effect of Sopung-san, we treated Sopung-san extract in animal model system induced contact hypersensitivity. Contact hypersensitivity, a local inflammatory response of the skin, was induced by 1% DNCB on the right ear of BALB/C mouse. Sopung-san was prepared as water extract and administrated everyday for 2 weeks per oral. A right ear of mouse was potently swelled by 1% of DNCB treatment, but a mouse ear thickness was significantly reduced by Sopung-san after 2 weeks. treatment. Sopung-san reduced IgG in serum obtained from blood of 1 % DNCB-treated mouse. IgE in serum was not changed by DNCB and/or Sopung-san treatment. $IL-1{\beta}$ and IL-6 from ear tissue were significantly increased by DNCB, Dut were not reduced by Sopung-san. From these results, anti-inflammatory effect of Sopung-san, especially reduction of ear swelling, might be partly due to reduction of IgG in serum.

  • We evaluated the hepatoprotective activity of crude hot-water extracts of the traditional Korean medicinal herb, Phellodendri Cortex (PC; Bark of Phellodendron amurense RUPR.), in an experimental model of hepatic damage induced by carbon tetrachloride ($CCl_4$). The serum marker of liver damage, sGOT, sGPT and sALP, were significantly decreased in the liver of the PC treated rats, compared with that of $CCl_4$ treated group. The histological observation of liver section of rats, showed the same protective effect of PC treatment. And the protective activity of PC was more significant in the post-treated group than pre-treated group. The significant decrease of malodialdehyde and increase of glutathion, catalase activity were observed in the liver homogenate of PC treated rats. Based on these findings, it is suggested that PC has potent hepatoprotective effects and the mechanism of the protection may be related to antioxidation pathways.

  • Oxidative stress has been implicated in cutaneous damage in various inflammatory skin diseases, including atopic dermatitis (AD). Atoberry is the herb medicine extract which is composed with Spirodelae Herba, Xanthii Fructus, Houttuyniae Herba, Taraxaci Herba, Retinervus Luffae Fructus, Platycodi Radix, and Scutellariae Radix. In this study, we investigated the antioxidant and anti-inflammatory effects of Atoberry in AD-like skin lesion NC/Nga mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinse (Df) extract. Atoberry significantly increased electron donating ability (DPPH), nitrite scavenging (NO) and superoxide dismutase (SOD) activities in dose dependant. Topically applied Atoberry significantly reduced clinical severity score, ear thickness and histological grade in AD-like skin lesion NC/Nga mice. In addition, the serum levels of IgE, NO and prostaglandin E2 were significantly reduced by Atoberry. Futhermore, skin tissue levels of SOD, catalase and glutathione peroxidase (GPx) were significantly reduced by Atoberry. These results demonstrate that topical application of Atoberry may be improve the AD-like skin lesion by antioxidant and anti-inflammatory effects.
