  • Tetrahydroisoquinoline (THI) compounds have various pharmacological actions in the cardiovascular system. Recently, we have synthesized 1-${\alpha}$-naphthylmethyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline, YS 49. In the present study, we evaluated the effect of YS-49 on positive inotropic and chronotropic action using isolated rat heart and on blood pressure and heart rate using anesthesized rabbit. Vasodilating action was also assessed in isolated rat thoracic aorta. YS 49, concentration-dependently relaxed rat aorta precontracted with phenylephrine (PE, 0.3 ${\mu}$M) and high potassium (high K$\^$+/, 65.4 mM). The 50% inhibitory concentration (IC$\sub$50/) of YS 49 in PE-induced and high K$\^$+/-induded contraction was 5.36 ${\mu}$M and 2.52 ${\mu}$M, respectively. In isolated rat atria, YS 49 increased both heart rate and force, and in anesthesized rabbit it decreased blood pressure but increased heart rate. In addition, to know the mechanism of action of the compound, propranolol, nonselective ${\beta}$-antagonist, and phentolamine, ${\alpha}$-blocker, were used. Furthermore, a comparison with the effect of higenamine, trimetoquinol on the vasodilating action in rat thoracic aorta was also made. The action of YS 49 was inhibited by the presence of propranolo, not pentolamine. These results indicate that cardiotonic and vasodilatory action of YS 49 is attributable, at least in part, for ${\beta}$-receptor stimulation.

  • Cervi Parvum Cornu is widely used as a hemopoietic, tonifying, growth-promoting, cardiotonic, and immuno-modulating agent in Korea. In order to develop the quality control method of Cervi Parvum Cornu by the identification of the biological source or origin, the molecular approach was applied using PCR (polymerase chain reaction) and PCR-RFLF (PCR-restriction fragment length polymorphism) analysis. In the PCR analysis of the mitochondrial 12S rRNA gene and cytochrome b gene regions, no distinctive DNA bands from Cervidae (deer) antlers and Rangifer (reindeer) antlers were observed. However, when the amplified products in the mitochondrial cytochrome b gene region were subjected to restriction digestion with TaqI, Cervidae antlers showed an undigested state of 380 by band, differently from two bands of 230 by and 1S0 by from Rangifer antlers. Based on this finding, the base sequences of amplified PCR products in the range of mitochondria) cytochrome b gene from Cervidae antlers and Rangifer antlers were determined and subjected to restriction analysis by various endonucleases. The results showed that antlers from Rangifer species could be simply discriminated with other antlers from 8 Cervidae species (Chinese deer, Russian deer, Hong Kong deer, New Zealand deer, Kazakhstan deer, elk, red deer and Sika deer) by PCR-RFLP analysis using AtuI, HaeIII, HpaII or Sau3AI(MboI) as well as TaqI in the range of the mitochondrial cytochrome b gene.

  • 심근 수축기전에 있어서 중심적인 역할을 하는 칼슘 이온과 Hienamine과의 상호작용을 비교 검토하였고 아울러 이 강심효과에 대하여 칼슘길항제인 란타눔과 verapamil을 사용하여 이에 미치는 영향을 관찰하였다. Higenamine은 적출 가토좌심방근에 대해 심근의 칼슘과 상호보완적인 상승 및 상가작용을 나타내었고 Higenamine $10^{-7}g/ml$은 0.058mM의 칼슘과 동등한 심근 수축증강효과를 나타내었으며 부자부타놀 분획물과 비교할 때 약 1,000배 정도 강력한 강심작용을 나타내었다. 또한 심근세포막의 칼슘유입을 억제한 조건인 란타눔과 verapamil처치시에도 Higenamine은 용량의존적으로 저하된 심근 수축력을 회복시킴으로 미루어 볼 때 Higenamine외 강심작용기전의 일부는 세포막을 통한 칼슘의 유입을 촉진시키는 것일 것으로 추측하였다.

  • Korean aconitum (Aconitum koreanum R. Raymond) as one of the botanical crude drugs which pertain to helleboraceae has been extensively applied in Chinese medicine during the past decades. It has been particularly used in immortal tonic among the folk remedies in China, however, its general uses comprehend diuresis, cardiotonic, analgesia, neuralgia, gout and, furthermore, even neoplastic effect. The components of aconitum have been acknowledged as aconitine, mesaconitine, hypaconitine, aconine and so on. The main ingredient, aconitine has the advantage of causing the atrial fibrillation, but, its pharmacological research has not been fully elucidated. Although there are many reports with regard to the pharmacological effects on the motility of several animal hearts, their conclusions have not been regretfully coincided yet. The authors hereby paid attention to this point of view and made experiment to examine the relationship between the alcohol extract of Korean aconitum and the motility of the isolated clam heart, making the use of several drugs related to the heart such as serotonin, acetylcholine, pilocarpine, physostigmine, barium chloride, procaine and quinidine. The cardiac movement of the isolated clam (Meretrix lusoria) heart in the standard sea water solution was recorded with the electric kymograph according to the Magnus method. The results of the experiment are as follows. 1. The motility of the isolated clam heart represents the tendency of gradual inhibition in proportion to the concentration of AK-A $10^{-4}$, $5{\times}10^{-4}$, and $10^{-3}$. 2. The cardiac inhibitory effect of AK-A $10^{-3}$ antagonizes the motility of the isolated clam heart pretreated with serotonin $10^{-6}$. 3. The cardiac inhibitory effect of AK-A $10^{-3}$ antagonizes the systolic state appealed by barium chloride $10^{-3}$. 4. The systolic state caused by quinidine $10^{-4}$ is not inhibited by AK-A $10^{-3}$.

  • Asclepias curassavica. Linn, an erect, simple (or) much branched perennial herb with a somewhat woody base, belonging to the family Asclepiadaceae. It has been reported to have multiple pharmacological effect of anti-inflammatory, cardiotonic, anticancer, anthelmintic and to treat piles and gonorrhoea. It is to be expected that several activities might be related to a possible antioxidant action from this plant. The hydro alcoholic extract of Asclepias curassavica was tested in vitro for its antioxidant activities, such as DPPH radical, nitric oxide radical, superoxide anion radical, lipid peroxidation assay, hydroxyl radical, reducing power, and total phenol content. The extract exhibited scavenging potential with $IC_{50}$ value of $8.7\;{\mu}g/ml,\;198.4\;{\mu}g/ml\;and\;21.7\;{\mu}g/ml$ for DPPH, nitric oxide and superoxide anion radicals. The values were found to higher than those of Vitamin-C, rutin, and curcumin, as standards. The extract showed 50% protection at the dose of $134.2\;{\mu}g/ml\;and\;41.4\;{\mu}g/ml$ in lipid peroxidation as well as deoxyribose degradation, those values more to that of standard, vitamin E $(IC50\;values,\;119.2\;{\mu}g/ml\;and\;32.5\;{\mu}g/ml,\;respectively)$. The reducing power of the extract depends on the concentration and amount of extract. Since a significant amount of polyphenol could be detected by the equivalent to $0.0495\;{\mu}g$ of pyrocatechol from 1 mg of extract. It can be concluded that hydro alcoholic extract of aerial part of Asclepias curassavica could be considered as potent antioxidant, which makes it suitable for the prevention of human disease.

  • In Chinese medicine, it is said that Aconiti tuber has cardiotonic, diuretic and analgesic effects. Kim et al reported that alkaloid free part of Aconiti tuber, $CHCI_3$ insoluble fraction, showed inotropic effect on isolated frog heart and inotropic effect is potenciated by n-butanol fractionation. To investigate the effect of Aconiti tuber butanol fraction on the mechanical and electrical properties of heart, change of active tension, excitability and refractory period of isolated rabbit atrium in the presence of butanol fraction were measured and the comparison with that of ouabain and quinidine was done. The observed results are as follows. 1. $5{\times}10^{-4}g/ml$ concentration of Aconiti tuber butanol fraction showed approximately same effect with therapeutic concentration of ouabain on the increment of contractile force, and the effect of $2{\times}10^{-3}g/ml$ was greater than that of $1{\times}10^{-5}g/ml$ of ouabain. 2. Acceleration of rate of contractile force increment in the presence of Aconiti tuber butanol fraction was greater than in ouabain, and the time to maximum tension was shorter in Aconiti tuber butanol fraction than in ouabain. 3. The excitability of isolated atrium was slightly increased at low concentration of Aconiti tuber butanol fraction, while decreased at higher concentration. 4. Aconiti tuber butanol fraction slightly prolonged refractory period of isolated right atrium at the concentration of $2{\times}10^{-3}g/ml$.

  • Ginger (Zingiber of oficinale Roscoe, Zingiberaceae) is one of the most frequently and heavily consumed dietary condiments throughout the world. Besides its extensive use as a spice, the rhizome of ginger has also been used in traditional oriental herbal medicine for the management of symptoms such as common cold, digestive disorders, rheumatism, neurologia, colic, and motion-sickness. The oleoresin from rhizomes of ginger contains [6] -gingerol (1- [4'-hydroxy-3'-methoxyphenyl]-5-hydroxy-3-decanone) and its homologs as pungent ingredients that have been found to possess many interesting pharmacological and physiological activities, such as anti-inflammatory, analgesic, antipyretic, antiheatotoxic, and cardiotonic effects. However, the effect of [6]-gingerol on cell proliferation in breast cancer cell are not currently well known. Therefore, in this study, we examined effect of [6]-gingerol on protein and mRNA expression associated with cell proliferation in MDA-MB-231 human breast. cancer cell lines. We cultured MDA-MB-231 cells in presence of 0, 2.5, 5 and $10{\mu}M$ of [6] -gingerol. [6]-Gingerol inhibited breast cancer cell growth in a dose-depenent manner as determined by MTT assay. ErbB2 and ErbB3 protein and mRNA expression were decreased dose-dependently in cells treated with [6]-gingerol (p<0.05). In addition, phosphorylated Akt levels and total hぉ levels were markedly decreased in cells treated with $2.5{\mu}M$ [6]-gingerol (p<0.05). In conclusion, we have shown that [6]-gingerol inhibits cell proliferation through ErbB2 and ErbB3, reduction in MDA-MB-231 human breast cancer cell lines.

  • The induction of apoptosis in target cells is a key mechanism for most anti-tumor therapies. Bufalin is a cardiotonic steroid that has the potential to induce differentiation and apoptosis of tumor cells. Research on bufalin has so far mainly involved leukemia, prostate cancer, gastric cancer and liver cancer, and has been confined to in vitro studies. The bufadienolides bufalin and cinobufagin have been shown to induce apoptosis in a wide spectrum of cancer cell. The present article reviews the anticancer effects of bufalin. It induces apoptosis of lung cancer cells via the PI3K/Akt pathway and also suppressed the proliferation of human non-small cell lung cancer A549 cell line in a time and dose dependent manner. Bufalin, bufotalin and gamabufotalin, key bufadienolides, significantly sensitize human breast cancer cells with differing ER-alpha status to apoptosis induction by the TNF-related apoptosis-inducing ligand (TRAIL). In addition, bufadienolides induce prostate cancer cell apoptosis more significantly than that in breast epithelial cell lines. Similar effects have been observed with hepatocellular carcinoma (HCC) but the detailed molecular mechanisms of inducing apoptosis in this case are still unclear. Bufalin exerts profound effects on leukemia therapy in vitro. Results of multiple studies indicate that bufalin has marked anti-tumor activities through its ability to induce apoptosis. Large-scale randomized, double-blind, placebo or positive drug parallel controlled studies are now required to confirm the efficacy and apoptosis-inducing potential of bufalin in various cancers in the cliniucal setting.
