Objectives : Skin color deformation by cupping has been widely used as a diagnostic parameter in Traditional Korean Medicine(TKM). Skin color deformation such as ecchymoses and purpura is induced by local vacuum in a suction cup. Since existing studies have relied on a visual diagnostic method, there is a need to use the quantitative measurement method. Methods : We conducted an analysis of cross-polarization photographic images to assess the changes in skin color deformation. The skin color variation was analyzed using $L^*a^*b^*$ space and the skin erythema index(E.I.). The meridian theory in TKM indicates that the condition of primary internal organs is closely related to the skin color deformation at special acupoints. Before conducting these studies, it is necessary to evaluate whether or not skin color deformation is influenced by muscle condition. Hence, we applied cupping at BL13, BL15, BL18, BL20 and BL23 at Bladder Meridian(BL) and measured blood lactate at every acupoint. Results : We confirmed the high system measurement accuracy, and observed the diverse skin color deformations. Moreover, we confirmed that the $L^*$, $a^*$ and E.I. had not changed after 40 minutes(p>0.05). The distribution of blood lactate levels at each part was observed differently. Blood lactate level and skin color deformation at each part was independent of each other. Conclusions : The negative pressure produced by the suction cup induces a reduction in the volumetric fraction of melanosomes and subsequent reduction in epidermal thickness. The relationship between variations of tissue and skin properties and skin color deformation degree must be investigated prior to considering the relationship between internal organ dysfunction and skin color deformation.

Tachyzoite antigens of Toxoplosnc gondii (RH) were partially purified by immunoaffinity chromatography. The cultivated ToxopLusmc in uiuo (mouse) and in nitro (Hep-2 cell) and peritoneal fluid of T. Bondii infected mice were collected for antigen analy- sis. Tachyzoite antigens collected from infected mouse showed positive bands of 76 kDa, 70 kDa,64 kDa, 53 kDa, 46 kDa, 44 kDa, 41 kDa, 35 kDa, 25 kDa, 18 kDa, and 13 kDa on immunoblot with anti-Toxoplcsmn rabbit sera, and those from infected Hep-2 cells revealed reactive bands of 70 kDa,64 kDa,53 kDa,35 kDa,28 kDa, and 13-10 kDa. After applying to an IgG-Sepharose column, two elusion peaks, E-1 and I-2 fractions, were obtained from both soluble antigen of T. gondii and the peritoneal fluid of infected mice, respectively. Immunoblots of soluble antigen with immunized rabbit sera revealed positive bands of 97 kDa, 63 kDa, 53 kDa and 35 kDa from I-1 fraction and 53 kDa and 35 kDa from I-2. In the case of the eluted peaks from mice peritoneal fluid, E-1 showed protein bands of 84 kDa,76 kDa,53 kDa and 29 kDa bands and 53 kDa and 45 kDa from I-2 on immunoblots. Serum IgG antibody titer of mice immunized with T gonnii tachyzoites was increased on 1 week after booster immunization when analysed by ELISA using crude antigen, while it was elevated on 3 weeks after booster immunization by ELISA using puri- fied antigen.

Background: The atrial fibrillation in patients with mitral valvular heart disease is frequently converted to sinus rhythm after the mitral valve surgery. This sinus restoration implies an important meaning in that it not only helps postoperative convalescence in patients with unstable hemodynamics but also reduces the rate of postoperative thromboembolism. Material and Method: We retrospectively analyzed 184 patients who received mitral valve surgery from June 1986 to December 1996 to investigate the trend of rhythm change following mitral valve surgery and thus to clarify the predisposing factors of postoperative sinus rhythm conversion and its maintenance. Result: The sinus rhythm was restored after the operation in 54 out of 139 patients with atrial fibrillation preoperatively(38.8%). However, the atrial fibrillation recurred in 41 patients at the time of discharge showing a recurrence rate of 75.9 percent. The mean duration of sinus rhythm in patients with eventual atrial fibrillation recurrence was 8.2${\pm}$5.9 days. Only 15 patients were in sinus rhythm at the time of late follow-up with the mean follow-up period of 84.4${\pm}$34.7 months. While the age, duration of symptoms, duration of atrial fibrillation, left atral size, and pulmonary artery pressure were thought to be the predisposing factors for sinus conversion after the operation, only the duration of atrial fibrillation and ejection fraction were considered risk factors for the recurrence of the atrial fibrillation following sinus conversion. Conclusion: This study suggests that the early operation is mandatory for the satisfactory result regarding postoperative rhythm. Moreover, additional operative measure in adjunct to the intervention of mitral valve should be considered for the maintenance of restored sinus rhythm as reflected by high postoperative recurrence rate of atrial fibrillation.

The sympathoadrenal system plays an important role in homeostasis in widely varing external environments. Conflicting findings, however, have been reported on its response to hypoxia. We investigated the effect of hypoxia on the sympathoadrenal system in dogs under halothane anesthesia by measuring levels of circulating catecholamines in response to graded hypoxia. Ten healthy mongreal dogs were mechanically ventilated with different hypoxic gas mixtures. Graded hypoxia and reoxygenation were induced by progressively decreasing the oxygen fraction in the inhalation gas mixture from 21%(control) to 15%, 10% and 5% at every 5 minutes, and then reoxygenated with 60% oxygen. Mean arterial pressure, central venous pressure and mean pulmonary arterial pressure were measured directly using pressure transducers. Cardiac output was measured by the thermodilutional method. For analysis of blood gas, saturation and content, arterial and mixed venous blood were sampled via the femoral and pulmonary artery at the end of each hypoxic condition. The concentration of plasma catecholamines was determined by radioenzymatic assay. According to the exposure of graded hypoxia, not only did arterial and mixed venous oxygen tension decreased markedly at 10% and 5% oxygen, but also arterial and mixed venous oxygen saturation decreased significantly. An increased trend of the oxygen extraction ratio was seen during graded hypoxia. Cardiac output, mean arterial pressure and systemic vascular resistance were unchanged or increased slightly. Pulmonary arterial pressure(PAP) and pulmonary vascular resistance(PVR) were increased by 55%, 76% in 10% oxygen and by 82%, 95% in 5% oxygen, respectively(p<0.01). The concentrations of plasma norepinephrine, epinephrine and dopamine increased by 75%, 29%, 24% in 15% oxygen and by 382%, 350%, 49% in 5% oxygen. These data suggest that the sympathetic nervous system was activated to maintain homeostasis by modifying blood flow distribution to improve oxygen delivery to tissues by hypoxia, but hemodynamic changes might be blunted by high concentration of nitrous oxide except PAP and PVR. It would be suggested that hemodynamic changes might not be sensitive index during hypoxia induced by high concentration of nitrous oxide exposure.

Background: The radial arteries are being used more often for coronary artery bypass grafting, We tried to the endoscopic radial artery harvest to reduce the cosmetic problems and neurologic complications of the conventional open harvesting and report the techniques and early results. Material and Method: The 86 patients underwent coronary artery bypass grafting between May 2003 and April 2005 had their nondominant radial artery endoscopically removed through a 2 cm incision at the wrist. The radial pedicle was dissected and was divided at antecubial area through a 5 mm counterincision. Result: The 23 patients complained of neuralgias on territory of superficial raidal none but no one complained of neuralgias on territory of lateral antebrachial cutaneous none. There was no functional impairment of the hand. There was no wound complication except a localized hematoma. All patients were contacted by telephone after postoperative 7.9$\pm$3.6 months. The 4 patients still complained of neuralgia. All the patients were satisfied with the aesthetics of the wounds. The multidetectional tomography was done on the 66 patients for the estimation of early patency of radial artery. There were 2 cases of stenosis and a case of occlusion. Conclusion: Endoscopic radial artery harvest had no functional impairment of the hand, lesser rate of neurologic complications and outstanding aesthetics. The results of early patency of the radial artery was similar to conventional methods. Therefore, we think that endoscopic radial artery harvest is the optimal procedure.

Food constituents analysis of Acer tegmentosum. Maxim.(Acer TM) stem was carried out according to AOAC method, and the antiradical activity on DPPH and cytotoxicity on human cell lines (AGS, HepG2, A549, MCF-7 and Chang) for the 80% ethylalcohol(EtOH) extracts of Acer TM stem were studied. The antiradical activity on DPPH radical of the ethylacetate(EtOAc) fraction of the bark showed a higher activity than that of $\alpha$-tocopherol, ascorbic acid and BHT. The inhibition activity of the 80% EtOH extracts from Acer TM stem on human cancer cell lines by SRB assay indicated a dose-dependent growth inhibition on most human carcinoma cells. The growth inhibition rate of each human cancer cell line showed 91.3% to AGS, 75.0% to A549, 74.1% to HepG2, and 70.2% to MCF-7 cells, respectively, when the 80% EtOH extract(1 mg/ml) of Acer TM stem was added.

This study was designed to examine the suitable characteristics of potential probiotic bacteria. Possible probiotic bacteria, including Lactobacillus acidophilus DDS-1, Lb. acidophilus B-3208, Bifidobacterium bifidum KCTC 3357, Lb. plantarum, Leuconostoc mesenteroides ssp. mesenteroides ATCC 8293, and Lactococcus lactis ssp. lactis ATCC 7962 were selected. We then measured their acid and bile tolerances, adhesion properties in the gastrointestinal tract, antimicrobial activity against pathogenic bacteria, and immunomodulation activity. The acid tolerances of Lb. acidophilus DDS-1, Lb. acidophilus B-3208, Lb. plantarum, and Leu. mesenteroides ssp. mesenteroides ATCC 8293, in PBS (pH 2.5) for 2 hr, were high enough that 50% of the inocula survived. The bile tolerances of all bacteria, except Lc. lactis ssp. lactis ATCC 7962, were also observed at a 3% oxgall concentration in MRS broth. The results of the adhesion property assay showed that the total binding affinities of Lb. acidophilus DDS-1, Lb. acidophilus B-3208, and B. bifidum were about three times higher than those of the other bacteria. In testing their antimicrobial activities against pathogens, Lb. acidophilus B-3208, B. bifidum KCTC 3357, and Lb. plantarum inhibited the growth of pathogenic bacteria. For their immunomodulation activity, the cell wall fractions from Lb. acidophilus DDS-1 and Lb. acidophilus B-3208 showed the highest bone marrow cell proliferation activities. However, the cell wall fractions of Lb. acidophilus DDS-1 and B. bifidum, and the cytosol fraction of Lc. lactis ssp. lactis ATCC 7962 showed higher macrophage stimulation activities than those of the other bacteria. Since Lb. acidophilus DDS-1 and Lb. acidophilus B-3208 satisfy the requirements for probiotics, they can be considered suitable probiotic bacteria.

In the recent studies, many researchers are interested in foods as functional components rather than nutrient sources. Cow's milk is considered as an excellent food sources because of its many nutrients. Casein is a major milk protein and has been reported to have hyperlipidemic and hypercholesterolemic effects. But several reporters have suggested that peptide fractions and hydrolysate of casein have hypolipidemic effects differing from intact protein, casein. Therefore, the objective of the study was to investigate how the casein peptide fractions affect lipid metabolism in rats fed normal or high fat diets. The peptide fractions and hydrolysate of casein were obtained by casein hydrolysis with trypsin. The male rats (Sprague-Dawley), weighing approximately 150 g, were fed each experimental diet containing casein (CAS), casein hydrolysate (CH), casein hydrolysate precipitate (Cpt) and two kinds of peptide fractions (CL & CB) for three weeks, respectively. In the exit I, the male rats were fed normal fat diets (7% soybean oil & cholesterol-free; Expt. I), and in the expt II, fed high fat diets (18% beef tallow & 1% cholesterol; Expt. II). Crude protein contents were calculated from nitrogen contents. Amino acid composition of each fraction was also analyzed. The concentration of total lipid, total cholesterol and triglyceride in serum, liver and feces were measured. As the results of study, tole rats fed peptide fractions with normal fat diets (Expt. I) had no effects on total lipid, total cholesterol and triglyceride concentration in serum and liver and fecal excretion. However, in the rats fed hydrophobic casein peptide fractions (CB) with high fat diet, fecal lipids excretion were significantly increased and the lipids concentration of serum and those of liver tended to decrease, numerically.

The objective of this study was to investigate the components and nutritional quality of red-tanner crab (Chionoecetes japonicus) paste in order to explore possibility for food processing source such as surimi gel containing crab paste. Yield of crab paste was $30\%$ from whole body after crushing and dehydrating. Crude protein contents $(9.5\%)$ of crab paste was lower than that $(13.1\%)$ of crab muscle, but fat $(0.5\%)$ and ash contents $(8.0\%)$ of paste were higher than $0.2\%\;and\;1.3\%$ of crab muscle, respectively. Volatile basic nitrogen (VBN) content of the crab paste was lower than those of the edible parts. Total amino acid content (9,497mg/l00g) of paste was lower than that (12,980mg/100g) of muscle. Aspartic acid, glutamic acid, lysine and leucine were the predominant amino acids in the protein fraction. The calcium content (6,539mg/l00g) was higher than those of phosphorus (579mg/100g), and potassium (793mg/100g) while manganese and iron were present in trace amounts. Major fatty acids of total lipid were 16:0, 18:1n-9, 20:5n-3 and 22:6n-3, and no difference of composition between paste and muscle. Sensory evaluation showed that scores of color and flavor of $15\%$ substituted surimi gel increased significantly when compared to surimi gel without crab paste (p<0.05). From the above results, the addition of crab paste enhanced nutrition and functionality of surimi gel.

Crude polysaccharide (CP) was fractionated from the submerged culture (containing both mycelia and culture broth, SC) with Phellinus linteus (PL) in mushroom complete medium (MCM) supplemented with ginseng extract ($65^{\circ}$Bx, GE) to enhance the immune activity. PL-GE-15-CP from SC cultivated in MCM supplemented with GE-15% (v/v, a ratio of MCM volume to GE) showed significantly higher macrophage stimulation (1.45 fold of the saline control at $100{\mu}g$/mL) than PL-GE-5 and 10-CP with GE-5 and 10%, or PL-CP from SC without GE. The potent intestinal immune system modulating activity through Peyer's patch was also obtained by PL-GE-15-CP (1.46 fold). When PL-GE-15-CP further fractionated on DEAE-Sepharose CL-6B (Cl- form), PL-GE-15-CP-II was the significantly higher than others from PL-GE-15-CP or PL-CP on macrophage stimulation, interleukin (IL)-12 production and intestinal immune system modulation (1.54, 3.96 and 1.56 fold, respectively). PL-GE-15-CP-II also had higher anti-metastatic activity against colon 26-M3.1 carcinoma cell (57.3% inhibition of tumor control, $200{\mu}g$/mouse) rather than PL-CP-II. This active fraction (PL-GE-15-CP-II) mainly contained neutral sugar (82.45%) and uronic acid (12.99%), and component sugar analysis showed that PL-GE-15-CP-II consisted mainly of uronic acid, Ara, Man, Gal and Glc (molar ratio of 0.52:0.97:0.63:1.00:0.54). Furthermore, the activity of GE culture was higher compared with culture without GE, indicating that GE helped to enhance the immune activity of P. linteus; also, it is assumed that the polysaccharide plays an important role in immune enhancement.
