Background & Objective : Idiopathic Lung Fibrosis(IPF) is chronic fibrotic interstitial pneumonia. The pathogenesis is unclear. Fritillariae Rhizoma is the most commonly used antitussive and expectorant Oriental medicinal herb. The effects of Fritillariae Rhizoma on bleomycin-induced lung fibrosis is here evaluated. Material and Methods : Fritillariae Rhizoma extract was daily given to the normal rats, control(bleomycin) rats and treated(bleomycin and Fritillariae Rhizoma) rats at 9.0 mg per body weight 10g for 14 days. 14 days later, the change in Leukocyte count and percentages were observed, as well as IFN-gamma and 1L-4 in BALF, and the change in Semiqualitative histological index(SHI). Results : Compared to control rats, Fritillariae Rhizoma treated rats showed a lower leukocyte count(P<0.05) lymphocyte, neutrophil percentage, SHI(p<0.05), IFN-gamma and IL-4(p<0.05) in treated rats. Conversely, macrophage percentages went higher(p<0.05) in treated rats. Conclusion : This study supports a role for Fritillariae Rhizoma in reducing the maintaining inflammatory cells and cytokines in rats with bleomycin-induced lung fibrosis and in the reduction of fibrosis tissues. Further research is needed in order to develop an effective treatment for lung fibrosis.

Perilla frutescens var. acuta Kudo (PF) is a traditional Korean medicinal herb for allergic reaction regulation. In the present study, we investigated the effect of 30% ethanol extract powder of PF (EPPF) and rosmarinic acid (RA), the active compound of EPPF on various allergic reactions using in vivo and in vitro models. EPPF and RA significantly inhibited compound 48/48-induced systemic anaphylactic reaction and histamine release (P < 0.05). In addition, EPPF and RA significantly inhibited passive cutaneous anaphylaxis (PCA) in a dose-dependent manner (P < 0.05). These effects were stronger than those of disodium cromoglycate, the reference drug tested. EPPF and RA also significantly inhibited production of inflammatory cytokines, tumor necrosis factor-a interleukin (IL)-6, and vascular endothelial growth factor on the PCA reaction and phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated human mast cell line, HMC-1 cells (P < 0.05). Moreover, EPPF and RA showed an inhibitory effect on lipopolysaccharide (LPS)-induced IL-4 production from whole spleen cells. Finally, EPPF and RA significantly decreased IL-4-dependent IgE production by LPS-stimulated whole spleen cells (P < 0.05). In conclusion, these results indicate that EPPF has potent anti-allergic activities.

Objectives : To prove the channel-tropism theory in herbology, we investigated the anti-diabetic effect of six herbal plants used for lower wasting-thirst in streptozotocin-induced diabetic rats. Methods : Diabetes was induced in male Sprague-Dawley rats by consecutive injection of streptozotocin (30 mg/kg i.p.) for 5 days. The rats were divided into normal control, diabetic control, and diabetic treatment with Lycii Radicis Cortex (LRC, 300 mg/kg); Corni Fructus (CF, 300 mg/kg); Bombyx Batryticatus (BB, 50 mg/kg); Lycii Fructus (LF, 300 mg/kg); Phellodendri Cortex (PC, 300 mg/kg); Epimedii Herba (EH, 300 mg/kg); and glibenclimide (10 mg/kg) as a reference drug. Herbal extracts or reference drug were administered orally for 28 days. The changes of body weight, food intake and water intake, and serological markers such as blood glucose, serum total cholesterol, triglyceride (TG), blood urea nitrogen (BUN), and creatinine (Cr) were measured. Results : The decrease of body weight and the increase of food and water intake in STZ-induced diabetic rats was improved by the administration of CF and LF. Also, the enhancement of blood glucose and serum total cholesterol, TG, BUN and Cr in STZ-induced diabetic rats was significantly inhibited by the administration of CF, BB, LF and glibenclimide. On the other hand, EH strongly inhibited the increase of BUN and Cr in the sera of STZ-induced diabetic rats. Conclusions : These results suggest that among six herbal medicines used lower emaciation of emaciation-thirst disease, CF, BB, LF and EH show a characteristics including the channel-tropism theory.

This research aims to test a new drug candidate based on a traditional medicinal herb, F1, an herbal extract obtained from Astragalus membranaceus and its main ingredient, 1-monolinolein that may have fewer side effects and less uterine hypertrophy. In vitro experiments, human osteoblast-like cell lines, MG-63 and Saos-2, were analyzed by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and an alkaline phosphatase (ALP) assays. Mouse osteoclasts were induced through a calcium-deficient diet and inhibition effects were measured. In vivo experiments were done using ovariectomized (OVX) rats for 9 weeks. At necropsy, uterus weights were measured, trabecular bone area (TBA) of tibia and lumbar vertebra were measured bone histomorphology. In results, cell proliferation and ALP activity in Saos-2 by ether F1 or 1-monolinolein did not increased significantly compared to the control. The F1 inhibited osteoclast development ($IC_{25}=3.37{\times}10^{-5}$mg/mL) less than 17$\beta$-estradiol. The OVX rats administered F1 (2 mg/kg/day and 10 mg/kg/day) showed an increase in TBA of the tibia significantly (136.3${\pm}4.2% and 138.5{\pm}$10.3% of control). In conclusions, the herbal extract, F1 inhibited tibia and lumbar bone loss and did not cause uterine hypertrophy. However, 1-monolinolein, the main ingredient of the herbal extract, did not inhibit bone loss.

Background and Objective: Coptidis Rhizoma is a medicinal herb known for its antioxidant and anti-inflammatory effect. The purpose of this study was to examine the effects of CR on the experimental burn elicitation in vitro and in vivo. Material and Methods: In order to know the antioxidant effect on skin cell of mice after burn elicitation, superoxide dismutase (SOD) activity was measured. In vitro, the RAW 264.7 macrophage cells were treated with lipopolysaccharides for experimental inflammation. iNOS mRNA expression was observed after CR-treatment. In order to know effects on the skin regeneration in the burned mice, we counted the nitric oxide (NO) in blood. We also observed the histological structure in the epidermal basal layer and the dermal section, and we studied changes of angiogenesis in the capillaries surrounding the basal layer and dermal papilla. The changes of transcription of iNOS mRNA (inducible nitric oxide synthase mRNA) and changes of NF-${\kappa}$B (nuclear factor ${\kappa}$B) p65 positive reaction were also observed to investigate the changes of the stress in the skin. Results: The results indicated that CR has significant effects on the antioxidant effect on skin cells of mice after burn elicitation by increasing SOD activity in the in vitro test. It seemed that CR decreased the amount of NF-${\kappa}$B which induced the iNOS mRNA dose-dependently and suppress activating NO and angiogenesis. Furthermore, CR facilitated the process of skin recovery after experimental burn. Conclusion: CR can be applied for burned skin via antioxidant effect and skin regeneration.

The traditional Asian medicinal herb, roots of Astragalus (A.) membranaceus (Leguminosae), is used for many purposes, some of which are purported to stimulate the release of growth hormone in vivo. Extracts of A. membranaceus were tested to determine whether they stimulate the release of growth hormone in rat pituitary cell culture. A. membranaceus was extracted sequentially with 80% ethanol (fraction A), n-hexane (fraction B); the test compound from the herbal extraction was isolated using silica gel column chromatography and was identified with spectral data. Test compound was also extracted by traditional boiling water methods. Induction of growth hormone in pituitary cell culture was conducted with isolated compounds and extracted fractions of A. Radix (dried roots of A. membranaceus). The fraction A was not active in the rat pituitary cell culture, but the fraction B derived from the ethanol fraction stimulated the release of growth hormone in culture. Six compounds from fraction B (1-6) were isolated and identified previously. The compounds 1,2-benzendicarboxylic acid diisononylester (1), $\beta$-sitosterol (2), and 3-Ο-$\beta$-D-galactopyranosyl-$\beta$-sitosterol (5) did not induce growth hormone release in the culture. Formononetin (3), 9Z, 12Z-octadecadienoic acid (4), stigmast-4-en-6$\beta$-o1-3-one (6) and 98-E, a mixture of 1'-9, 12-octadecadienoic acid (Z,Z)-2',3'-dihydroxy-propylester (7) and 1'-hexadecanoic acid-2',3'-dihydroxy-propylester (8) stimulated the release of growth hormone in the rat pituitary cell culture significantly compared to the control. In conclusions, four compounds isolated from extracts of A. Radix induced growth hormone release in the rat pituitary cell culture. The 98-E isolate was the most active inducer of growth hormone release.

Carbon tetrachloride ($CCl_4$)-induced liver injury depends on a toxic agent that has to be metabolized by the liver NAPDH-cytochrome P450 enzyme system to a highly reactive intermediate. Alternations in the activity of cytochrome P450 enzymes affect the susceptibility to hepatic injury from $CCl_4$. In this study, we evaluated the potential protective activity of the traditional Korean medicinal herb, Corni fructus (CF), against an experimental model of hepatotoxicity induced by $CCl_4$. The CF exhibited a hepatoprotective activity against $CCl_4-induced$ liver damage in Sprague-Dawley (SD) rats, as measured by GOT, GPT, ALP and histological observation. The CF also showed significant decrease of malodialdehyde (MDA) and increase of glutathion (GSH), catalase activity in rat liver homogenate. In addition, the expression of CYP2E1, as measured by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot analysis, was significantly decreased in the liver of CF treated SD rats. But $CCl_4$ and CF has no significant effect on 1A1 and 3A1 isoform of cytochrome P450. Based on these findings, it is suggested that hepatoprotective effects of CF possibly related to antioxidative effects and regulation of CYP2E1 expression.
