  • Hemostatic function is regarded to be preserved after an off-pump coronary artery bypass grafting (CABG), compared to conventional CABG, and the preserved hemostatic function may increase thrombotic occlusion of the graft. We studied the changes of hemostatic variables in patients undergoing off-pump CABG, and compared to those of on-pump CABG. We studied the changes of coagulation function in 11 patients who underwent off-pump CABG (group I), and compared them with those of 11 patients who underwent on-pump CABG and Dor procedure (group II). Coagulation status was evaluated by thromboelastography and blood coagulation test preoperatively, postoperative 1$^{st}$ day, 2$^{nd}$ day, 3$^{rd}$ day, and 5$^{th}$ day, respectively. Among the variables measured by thromboelastography (such as r time, k time, $\alpha$ angle, and MA value) and blood coagulation test (such as factor Ⅶ, protein S, protein C, antithrombin III, activated protein C resistance test, plasminogen, D-dimer, prothrombin time, activated partial thromboplastin time, platelet count, hemoglobin, and fibrinogen), there were significant differences in the MA value, $\alpha$ angle, and platelet counts between the two groups. MA values were 140$\pm$72% and 153$\pm$98% in group I, and 87$\pm$27% and 78$\pm$28% in group II, at postoperative 3$^{rd}$ and 5$^{th}$ days, respectively (p<0.05). $\alpha$ angle was 122$\pm$92% in group I and 69$\pm$23% in group II at postoperative 3$^{rd}$ day (p=0.09). Platelet count was 63$\pm$55% in group I and 33$\pm$13% in group II at postoperative 3$^{rd}$ day (p<0.05). Patients who underwent off-pump CABG showed increased coagulability during postoperative periods, compared to those who underwent on-pump CABG. Our data suggest that aggressive perioperative anticoagulation therapy is warranted in patients undergoing off-pump CABG. CABG.

  • Arterial thromboembolism (ATE) is a common and fatal complication of hypertrophic cardiomyopathy (HCM) in cats. Therefore in this study, we evaluated the hypercoagulability (using plasma concentration of D-dimer) in HCM cats with different stage of heart failure and left atrial enlargement and also investigated the any correlation with echocardiographic indices (including left free wall thickness at diastole, interventricular septal thickness at diastole, LA to Ao ratio, heart failure stage, existence of systolic anterior motion of mitral valve). The median plasma D-dimer concentration in this study population was $0.51{\pm}0.70$ (range 0 to 2.50) ug/mL in the control group, $1.47{\pm}1.29$ (range 0.3 to 5.79) ug/mL in the HCM group, $1.48{\pm}1.65$ (range 0.3 to 5.79) ug/mL in the ISACHC I group, $1.62{\pm}0.4$ (range 1.31 to 2.07) ug/mL in the ISACHC II group, $1.36{\pm}0.91$ (range 0.3 to 2.31) ug/mL in the ISACHC III group, $1.90{\pm}1.60$ (range 0.3 to 5.79) ug/mL in the cat with LA dilation, $1.72{\pm}0.72$ (range 0.6 to 2.31) ug/mL in cats with SEC-T, $1.19{\pm}0.70$ (range 0.3 to 2.31) ug/mL in the cats with SAM, and $1.63{\pm}0.80$ (range 0.6 to 2.31) ug/mL in the cats with ATE. Our study found the median and mean concentration of plasma D-dimer was higher in cat with HCM, ATE, SECT and SAM and clearly provides evidence of hypercoagulability in cats with HCM, although the severity was not correlated to the dilation of LA and the presence of heart failure. This is the first study evaluating the hypercoagulability in cats with HCM in Korea.

  • The effects of growth regulators, sucrose and gelling agents were investigated to increase the efficiency of the callus growth and plant regenerarion in tissue culture of Angelica koreana Max. The fresh weight and dry weight of subcultured callus was highest in MS medium supplemented with 1 mg/l 2,4-D. Callus growth was excellent in 2% sucrose, but it was inhibited in propotion to sucrose content. Effect of gelling agents on callus growth was highest on 1.2% agar and 0.4% Gelrite medium, respectively. The browning of callus was protected on the media supplemented with 10 mg/l ABA and 5 or 10 mg/l $AgNO_3$. In the callus induction and growth from the peduncle of immature inflorescence, 2,4-D was more effective than NAA, and the frequency of callus induction was highest as 81.7% in 2 mg/l 2,4-D. Plant was not regenerated from the callus derived from young leaf. Somatic embryos were developed from the surface of callus drived from the peduncle of immature inflorescence in the medium containing 0.5 mg/l 2,4-D, 1 mg/l kinetin, 5 mg/l ABA and 5 mg/l $AgNO_3$. Plants were developed from the matured somatic embryos in the medium supplemented with 0.2 mg/l 2,4-D and 1 mg/l kinetin.

  • This study was performed to identify the cheese starter potential of antifungal lactic acid bacteria isolated from Kimchi. Eight fungi were isolated from cheese or the cheese ripening room, and identified as Penicillium and Cladosporium by ITS-5.8S rDNA analysis. Twenty-two lactic acid bacteria species with antifungal activity were isolated from Kimchi, and identified as Lactobacillus and Pediococcus by 16S rRNA sequence analysis. Six lactic acid bacteria species were selected (L. sakei subsp. ALJ011, L. sakei subsp. ALI033, L. sakei subsp. ALGy039, P. pentosaceus ALJ015, P. pentosaceus ALJ024, and P. pentosaceus ALJ026) based on higher antifungal activity from the initial 22 species. Out of the six identified species, L. sakei subsp. ALI033 had the highest antifungal activity. For growth of the six lactic acid bacteria, optimal temperature and pH were $30{\sim}37^{\circ}C$ and 7.0, respectively. Proteolytic activities of the six lactic acid bacteria were almost as strong as the commercial strain Str. thermophilus Body-1. Coagulative activities of L. sakei subsp. ALI033, P. pentosaceus ALJ015, and P. pentosaceus ALJ024 were higher than those of L. sakei subsp. ALJ011, L. sakei subsp. ALGy039, and P. pentosaceus ALJ026. The acid resistance of L. sakei subsp. was higher than that of P. pentosaceus. The major organic acid component of the lactic acid bacteria culture medium was lactic acid.

  • In order to study the effects of Gagamyounjo-Tang(加減潤燥湯) on the experimentally hypercoagulable state and hyperlipidemia in rats, we have made the hypercoagulable state in rats by injection of Bothrops jararaca venom (0.1ml/200g : Control group), and have administered solid extract of Gagamyounjo-Tang(加減潤燥湯)(132mg/200g : Sample group). After 1 hour we measured the platelet count, fibrinogen level, APTT, FDP and D-dimer. And we have made the hyperlipidemia in rats by injection of Triton WR-1339 for 3 days(30mg/200g/day : Control group), and have administered solid extract of Gagamyounjo-Tang(加減潤燥湯)(132mg/200g : Sample group), then we measured the total cholesterol, triglyceride, phoshpolipid and HDL-cholesterol levels. The results are summarized as follows : 1. In the hypercoagulable state, Sample group significantly decreased in platelet count compared with Control group(p<0.01), and significantly prolonged in APTT compared with Control group(p<0.05). 2. In the hyperlipidemia, Sample group significantly decreased in the total cholesterol, triglyceride and phoshpolipid compared with Control group(p<0.01), and significantly increased in HDL-cholesterol level compared with Control group(p<0.01). According to the above experimental results, Gagamyounjo-Tang(加減潤燥湯)is assumed to have curative effects against the hypercoagulable state in rats induced by Bothrops jararaca venom and the hyperlipidemia in rats induced by Triton WR-1339. And we can suppose that Gagamyounjo-Tang(加減潤燥湯) has a curative effect against the cerebrovascular accident caused by blood stasis.

  • Mast cell is a cell that functions mainly in our body with a respect to inflammation and allergic response. Bee venom has been progressed in a study as a model related to mechanism in alleviation of pain until now, but it is being progressed in a study relevant to immunocyte in anti-inflammation or anti-allergic response. The present study is aimed to present the basis related to a future study of gene, by researching the influence of melittin and MCD Peptide, which are major ingredients in Bee venom, upon the expression of gene in the mast cell strain. In this study, it dealt with melittin and MCD Peptide respectively, in the effective concentration after passing though the experiment of cytotoxicity by using human mast cell strain. Also, with the respect in the aspect of expression in gene that changes at this time, information was obtained through the technique of analyzing microarray. Through experimental statistics, when regarding a case that global M is significant in more than 1 or -1, in melittin, all 7 genes were accelerated, and 8 inhibited. In MCDP, 7 genes were accelerated and 17 genes inhibited. The function in the body to which these genes are related, was associated with the protein binding within a cell, the activation in the function of lymphocyte, the acceptor related to macrophage antigen. In cell nucleus, substance related to GABA A receptor, protein associated with cAMP reactive element, substance related to complement system No.8 and to B-cell, protein substance related to polycystic kidney disease, substance related to inflammation, and the protein substance of influencing coagulation of blood. Through these results of analysis, it could obtain more useful materials in clarifying the mechanism of action in melittin and MCD peptide, which are in charge of mainly medical action in the abdomen. Also, it is thought that an in-depth study on the influence of main ingredients in Bee venom, the wholly honey bee venom aqua upon anti-allergic response or anti-inflammation are further required.
