  • These studies were conducted to investigate the effect of Yijin-tang on the anticonvulsion, analgesic, sedative actions, effect on blood vessels and blood pressure. The result of these studies was summarized as follows; Suppressive action was shown on convulsion due to cerebrocortical causes, but no such actions were noted either myelic or diencephaltic causes in mice. Analgesic and sedative actions were significantly recognized in mice. Increasing of blood pressure and vasocontractive actions were noted.

  • Drugs processed using nanobiotechnology may be more biocompatible, with sustainable and stabilised release or action. L-asparaginase produced from fungi has many advantages for treatment of lymphocytic leukemia with lesser side effect. In the present work, maghemite nanobiocomposites of fungal asparaginase were produced using glutaraldehyde-pretreated colloidal magnetic nanoparticles. Formation of nanobiocomposites was observed using laser light scattering and confirmed by UV-visible spectrophotometry with the absorption peak at 497 nm. The specific asparaginase activity was increased from 320 U/mg with crude asparaginase to 481.5 U/mg. FTIR analysis confirmed that primary amines are the functional groups involved in binding of asparaginase on magnetic nanoparticles. The average size of the produced nanobiocomposite was found in the range of 30 nm to 40 nm using histogram analysis. The magnetic nanobiocomposite of asparaginase synthesised using glutaraldehyde showed 90.75% cytotoxicity against human colon adenocarcinoma cell lines. Hence it can be used as an active anticancer drug with an augmented level of bioavailability.

  • In the preliminary antitumor screening tests of Crude Drugs and collected plants, the methanol ic extract of Forsythia Fruits in Korean marcket showed signif icant cytotoxic activity against Chinese hamster V-79 cells, but that in Japanese market did not. The former was identifid as Forsythia viridissima Lindley and latter as F.suspensa Vahl on the basis of the morphological observation. When an aqueous solution of the extract prepared from the fruits of F. viridissima (Oleaceae) was partitioned successively with n-hexane, methylene chloride, n-butanol, the cytoyoxic activitywas concetrated in the methylene chloride extract. Fractionation of the extract was made with the guidance of bioassay against V-79 cells to give cytotoxic lignans, matariresiol (1) and arctigenin (2). Their ICso values of compounds 1 and 2 were respectively $7.8{\;}\mu\textrm{g}/ml$ 1 and $1.65{\;}\mu\textrm{g}/ml$. Also, their structures were confirmed by comparison of physical and spectral data in the literature.

  • Dopamine ${\beta}-hydroxylase$ (DBH) catalyses the enzymatic reaction of dopamine to norepinephrine. For the purpose of isolating DBH inhibitors from natural resources, thirty one kinds of medicinal plants were screened by tracing the inhibitory activities against bovine adrenal DBH, utilizing tyramine as a substrate. Among the crude drugs tested, leaves of Lactuca sativa L., Gardeniae Fructus, Magnoliae Flos and Scutellariae Radix showed potent enzyme inhibitory activities against DBH.

  • Experimental studies were implemented to evaluate clinical efficacy of 'Daeshiho-Tang' and to validate Oriental medicine description of the recipe which has been widely used in metabolic diseases and febrile diseases. Following results were obtained; 1. Suppressive action was shown on convulsion due to cerebrocortical causes but no such action was noted either myelic or diencephatic causes in mice. 2. Analgesic and antipyretic actions were recognized in mice, rats and rabbits. 3. Antispasmodic actions were recognized on contraction of the ileum induced by $BaCl_2$ and histamine in mice and guinea-pigs. 4. Transport accelerating action of the small intestine was gained in mice.

  • Ohyaksungisan, combined preparation of crude drugs, has been used for hemiplegia, arthralgia and paralysis in traditional Korean medicine. The anti-inflammatory activity of the aqueous extract from Ohyaksungisan(OSSE) was investigated on acetic acid-induced edema and adjuvant arthritis in rats. Acute toxicity and analgesic action in mice were also examined. Its anti-inflammatory activity on 5% acetic acid-induced edema and adjuvant arthritis was observed with oral administration. The acute toxicity showed 10% mortality at 2400 mg/kg (p.o), but was not showed at 1200 mg/kg (i.p). OSSE was showed to have significant analgesic action (P<0.05) at 150 mg/kg and this action was strengthened at 300, 600 mg/kg. The anti-inflammatory effect was showed significant preventive effect on the hind paw edema from 90 min. and the adjuvant arthritis, when orally administered for 19 days. showed significant inhibitory effect on the hind paw edema from the 5th day.

  • Effects of Lycium chinensis, Epimedium koreanum and tuguaconitine which is isolated from Aconitum sibiricum on primary culture chicken embryonic brain cells were studied by microscopic observation and determined of the activity of pyruvate dehydrogenase complex(PDHC). Brain cells were prepared from the brain of 10-day-old chicken embryo and cultured with a medicine consisted of 90% Dulbecco's Modified Eagle Medium(DMEM) and 10% horse serum. It was observed that all substances studied seemed to show the tendency to stimulate the neurite outgrowth of brain cells which were cultured with a deficient medium under microscopic observation. The activity of PDHC in brain cells cultured with a deficient medium was increased by Lysium chinensis and Epimedium koreanum. However, tuguaconitine had not influence on the activity of PDHC.

  • It has been known that Magnolia officinalis, Magnolia and Machilus Barks are reputed to be effective in 'Hagi', 'Sanman' and to be analgesic but there was differences of efficacy of these crude drugs against the kinds and habitates. For this reason, this study was conducted to compare the acute toxicities, analgesic effects and motilities of isolated intestine. This results obtained in this work were summarized as follow: 1. In the test of acute toxicies, Machilus bark was found to be more toxic than the others. 2. Both these was found to have analgesic effect. 3. In the effects against the motility of isolated intestine, Magnolia officinalis and Magnolia barks were found to be relaxant, Machilus bark was found to be contractive. From these results, Magnolia officinalis and Magnolia barks might have analgesic effect and relaxant effect of intestine.

  • This study was undertaken to investigate effects of 'Oyo-Tang' on the respiratory system. The results of this study were summarized as follows; 1. Antihistamine and relaxed dialating actions were recognized on the extracted ileum and serial broncheal samples in guinea-pigs. 2. Mild hypertensive action was recognized on the carotid artery in rabbits. 3. Antitussive action was noted on mechanically irritated coughs in dogs and cats. In connection with the results of these studies, effects based on the Oriental medical references were consistent with the actual experimental results. It was considered that effective application of 'Oyo-Tang' for the treatment of cough and asthma could be justified.
