  • Objectives : This experiments were performed to determine the effect of Linderae Radix extract on norepinephrine-induced arterial contraction in rabbit. Methods : In order to investigate the effect of Linderae Radix extract on contracted rabbit carotid arterial strips, transverse strips with intact or damaged endothelium were used for the experiment using organ bath. To analyze the mechanism of Linderae Radix extract-induced relaxation, Linderae Radix extract infused into contracted arterial strips induced by norepinephrine after treatment of indomethacin, tetraethylammonium chloride, $N{\omega}-nitro-L-arginine$ or methylene blue. Results : Linderae Radix extract relax arterial strip with endothelium contracted by norepinephrine, but in the strips without endothelium, Linderae Radix extract-induced relaxation was significantly inhibited. Linderae Radix extract-induced relaxation was decreased by the pre-treatment of $N{\omega}-nitro-L-arginine$ or methylene blue, but it was not observed in the strips pre-treated with indomethacin or tetraethylammonium chloride. When $Ca^{2+}$ was applied, the strips which were contracted by norepinephrine in a $Ca^{2+}$-free solution, arterial contraction was increased. But pre-treatment of Linderae Radix extract inhibited contractile response to norepinephrine and $Ca^{2+}$. Conclusions : We suggest that Linderae Radix may suppress influx of extra-cellular $Ca^{2+}$ through the formation of nitric oxide, and release of intra-cellular $Ca^{2+}$.

  • Linderae Radix, the dry roots of Lindera aggregata (Sims) Kosterm, has long been used as traditional Chinese medicine for treatment of inflammatory diseases. The total alkaloids are believed to be the active components responsible for anti-inflammation of Linderae Radix. Here, the total alkaloids of Linderae Radix were extracted and isolated, including 12 isoquinoline alkaloids and 1 furan sesquiterpene. Within the alkaloids, norisoboldine, boldine, linderaline, isoboldine, reticuline, N-methyllaurotetanine, norjuziphine were found to be the major ingredients. In lipopolysaccharide-treated macrophage RAW 264.7 cells, application of Linderae Radix extract, or total alkaloids, suppressed the transcription of proinflammatory cytokines, interleukin-$1{\beta}$ and interleukin-6. Out of the 12 alkaloids, norisoboldine, boldine, and isoboldine were tested in lipopolysaccharide-treated macrophages, and norisoboldine was the strongest alkaloid in suppressing the cytokine expressions. The current studies suggested that the identification of alkaloids from Linderae Radix could provide a plausible explanation for herbal therapeutic functions.

  • The purpose of this study was to examine the anti-depressive effects of OnDam-Tang with addition of Linderae Radix (ODT-L) on the animal model of depression induced by chronic immobilization stress. Depression model was made by chronic immobilization stress for 2 hours for 21 days. And we performed forced swimming test, analysis of the neurotransmitter and immunohistochemical staining, measured expression levels of serotonin in the brain. ODT-L has decreased immobilization time in forced swimming test. ODT-L has increased amount of melatonin in the brain. ODT-L has increased expression levels of serotonin in the brain. ODT-L prevented damage in the hippocampal region. ODT-L has reduced the expression level of CRF receptors in in hippocampus region. These results suggest that ODT-L may have anti-depressive effects on depression.

  • Tyrosinase is a key enzyme to control the biosynthesis of melanin pigments and has two enzyme activities, namely of 1-tyrosine hydroxylase and of 1-dopa oxidase. Thus, tyrosinase is regarded as a target in skin-whitening and therapeutic intervention of local hyperpigmentation diseases. We have tested tyrosinase inhibitory activity on the water extracts of 50 species oriental medicinal plant. Among them, five medicinal plants, Linderae Radix, Clematidis Radix, Cinnamomi Cortex Spissus, Fritillariae Thunbergii Bulbus and Bulbus Fritillariae Cirrhosae were investigated strong inhibition effect. Five medicinal plants were fractionated using organic solvents (methylene chloride, ethyl acetate, n-butanol, water). Cinnamomi Cortex Spissus (ethyl acetate fraction) was investigated strong inhibition effect. Tyrosinase inhibitory activity below $IC_{50}\;40{\mu}g/ml$ is confirmed in five herbal plants that are Linderae Radix, Clematidis Radix, Cinnamomi Cortex Spissus, Fritillariae Thunbergii Bulbus and Bulbus Fritillariae Cirrhosae. Tyrosinase inhibitory levels ($IC_{50}\;{\mu}g/ml$) of each plants were 15.56, 35.02, 25.14, 15.20 and 39.77. We also investigate the effect of effective plant's fraction. in dose of $100{\mu}g/ml$, Cinnamomi Cortex Spissus (P-36) EtOAc fraction significant inhibitory effect over 50%. Clematidis Radix (P-35) and Cinnamomi Cortex Spissus (P-36) MC fraction inhibit tyrosinase each 36.60% and 43.21%. inhibitory rates of Fritillariae Thunbergii Bulbus (P-40) EtOAc and $H_2O$ fraction are 31.40% and 31.51%. Bulbus Fritillariae Cirrhosae (P-45) BuOH fraction regulate tyrosinase activity to 37.71%. We examined tyrosinase inhibitory activity of natural products and these results suggest that several herbs have potential as a new whitening material.

  • The water extracts of ten crude drugs were tested for the spasmolytic and anti-peptic ulcer activities on rat ileum smooth muscle contraction and aspirin-induced acute hemorrhag ic erosive gastritis respectively. The water extract of Aurantii immaturi pericarpium(AIP)($IC_{50}=1.5{\times}1O^{-2}$g/l), Aurantii nobilis pericarpium(ANP)($IC_{50}=2.5{\times}1O^{-2}$g/l), Cyperi rhizoma(CR)($IC_{50}=3.3{\times}1O^{-2}$g/l). Linderae radix(LR) ($IC_{50}=6.8{\times}1O^{-2}$), Aurantii fructus immaturus(AFI)($IC_{50}=11.8{\times}1O^{-2}$), Saussureae radix(SR)($IC_{50}=13.2{\times}1O^{-2}$g/l) and Ponciri fructus(PF)($IC_{50}=23.3{\times}1O^{-2}$g/l) showed inhibitory activity on the isometric contraction of rat ileum smooth muscle induced by electrical stimulation in a concentration-dependent manner, whereas the water extracts of Arecae pericarpium(AP), Agastachis herba(AH) and Magnoliae cortex(MC) potentiated the isometric contraction. In the aspirin-induced acute gastritis, the water extracts of MC, AP and CR reduced significantly the gastric juice secretion, gastric juice acidity and pepsin activity. They also showed protective activity of gastric mucosal layer from erosion and petichial hemorrhage in gross and histological examination.

  • This study was performed to investigate concept, systoms, causes of disease, pathogenic mechanisms, therapies and precriptions about senile constipation through the successive medical literature, recent chinese medical literature and chinese medical joumals. Senile constipation seems to be applicable to dryness syndrom and constipation of insufficiency type, have something to do with kidney(the most), lung, spleen and large intestine. The most principal cause of disease is yin-fluid, the rest deficiency of qi, insufficiency of yang, stagnation of qi and retention of fever etc. There are enriching the blood and moistening dryness in principal therapy, the rest are invigorating qi and loosing the bowel, warming and invigorating the spleen and kidney, regulating the flow of qi and promoting the stagnancy of qi and expelling the pathogenic heat etc. In prescriptions there are Yunjangtang, Jengaektang, Hwanggitang, Jechunjeon, Yukmatang and Majainhwan as the causes of disease, meanwhile are Yungjang-tang, Jechunjeon and Majainhwan in the vulgaris prescriptions. And in medical herbs there are nourishing yin medicines as Rhizoma rehmanniac, Radix ophiopogonis and Radix scrophulariae etc., invigorating qi medicines as Radix astragali, Radix codonopsitis and Radix polygoni multiflori etc, invigorating yang medicines as Caulis cistanchis and Semen psoraleae etc., promoting qi circulating medicines as Radix saussurea, Lignum aquilariae and Radix linderae etc., and reducing fever and therapeutic method to keep the adverse qi flowing downward medicines as Semen cannabis, Rhizoma rhei, Fructus immaturus ponciri, and Cortex magnoliae etc.. Meantime Rhizoma rehmanniae, Radix ophiopogonis, Caulis cistanchis, Radix angelicae gigantis, Semen cannabis, Semen biotae, Semen pruni japonicae and Semen persicae in principal herb-medicines. In clinical reports the process of disease was between 10 to 20 years, the evacuation cycle between 4 to 7 days, generally possessed chronic diseases as hypertension, diabetes, arteriosclerosis and cerebro- vascular disorders etc. and the efficiency rate was more than 90%. The senile constipation is occured in succession or promoted by chronic diseases as obesity, hypertension, diabetes, arteriosclerosis. hrperlipemia, cerebro- vascular disorders etc., so diet-regulating, adequate exercise, proper evacuation-habit and psychologic rest etc. are important more than medicine-treatments.

  • Objectives : This study evaluates the neuroprotective effects of Sopung-tang, a mixture of Notopterygii Rhizoma, Saposhnikoviae Radix, Angelicae Gigantis Radix, Cnidii Rhizoma, Hoelen, Aurantii Nobilis Pericarpium, Pinelliae Tuber, Linderae Radix, Angelicae Dahuricae Radix, Cyperi Rhizoma, Cinnamomi Ramulus, Asari Radix, Glycyrrhizae Radix on the cerebral infarct combined with hyperlipidemia. Method : The hyperlipidemia was induced by the beef tallow 30% diet for 14 days on Sprague-Dawley rats. The cerebral infarct was induced by the middle cerebral artery occlusion (MCAO) for 2 hours with intraluminal thread method. Then the water extract of Sopung-tang was administered a day for 5 days at 3 hours after the cerebral infarct by MCAO. Effect of Sopung-tang was evaluated with the infarct volume and edema percentage by a TTC-stained brain section, and the expressions of Bax and Bcl-2 in the brain tissue by a immunohistochemical stain method. Results : Sopung-tang reduced the infarct size partly in a TTC-stained brain section of the hyperlipidemic MCAO rats. Sopung-tang reduced the infarct volume of the hyperlipidemic MCAO rats significantly. Sopung-tang reduced the edema percentage of the hyperlipidemic MCAO rats, but not significant statistically. Sopung-tang suppressed the Bax expressions in the cerebral penumbra and caudate putamen of the hyperlipidemic MCAO rats significantly. Sopung-tang upregulated the Bcl-2 expression in the caudate putamen of the hyperlipidemic MCAO rats. Conclusion : These results suggest that Sopung-tang plays an anti-apoptotic neuroprotective effect through the suppression of Bax and up-regulation of Bacl-2 expressions in the brain tissues.

  • Some crude drugs in ancient literatures have been used as traditional therapeutic agent of leucorrhea mainly caused by Trichomonas vaginalis and Candida albicans. Sixty six kinds of crude drugs in ancient literatures and ten constituents were selected as sample drugs. Trichomycin standard was tested to compare with the above drugs. To determine the anti-fungal effect of these drugs on Candida albicans Yu 1200, a test organism, screening test was conducted. Antifungal activities of crude drug water extracts were observed by means of two test methods : firstly through the agar slant method and secondly the counting chamber method which was used for acknowledged drug agents upon the result of the agar slant method. And in order to improve the fungicidal effect, the organisms were stained with 0.02% methylene blue solution. The results of the above test indicated that Fritillariae Rhizoma has antifungal action in the concentration of 310mcg/ml, Coptidis Rhizoma in 620mcg/ml, Meliae Cortex, Scutellariae Radix both in 5,000mcg/ml. Baicalin, catechol among the pure isolated constituents inhibited in the range of 50mcg/ml. This score was based on 50% inhibition in comparison with amounts of control organisms. Rhei Rhizoma, Mori Radicis Cortex, Linderae Radix, and Amomi globosi Fructus showed the antifungal effect moderately in 5,000mcg/ml, and baicalein and pectolinarin in 50mcg/ml in the limit of between 35% and 50% antifungal activity. Staining with 0.02% methylene blue showed that any of the crude drug extracts was unable to stain the cells, but trichomycin in 0.86unit/ml able to stain 12% of the cells. This result means that crude drugs probably do not have fungicidal but fungistatic action.
