Objectives : The purpose of this study was to investigate Acute$\cdot$Subacute Toxicity and Anti-cancer Effect of K-Herbal-acupuncture in mice and rats. Methods : Balb/c mice were injected intraperitoneally with K-herbal-acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were injected intraperitoneally with K-herbal-acupuncture for subacute toxicity test. K-Herbal-acupuncture was injected on abdomen of mice with S-180 cancer cell line. Result : 1. $LD_{50}$ of K-Herbal-acupuncture was limited $4{\times}10^{-3}$ml/kg~$2{\times}10^{-3}$ml/kg by the test. 2. In acute toxicity test, all of mice were down to the moving reflex, but the weight of mice was increased in treatment group, compared with the normal group. (P<0.05) 3. In acute toxicity test of serum biochemical values of mice, glucose was increased in treatment II group, total cholesterol was increased both treatments.(P<0.05) 4. In subacute toxicity test, the clinical signs of toxication was down to the moving reflex, but it is not severe like acute toxicity test, and observed weight loss at the treatments. 5. In subacute toxicity test, liver weight was decreased compared with the normal group. (P<0.05) 6. In subacute toxicity test of complete blood count test (CBC) of rat, HCT was decreased in treatments, compared with the normal group.(P<0.05) 7. In subacute toxicity test of serum biochemical values of rat, uric acid and triglyceride were decreased, and glucose was increased in treatment groups compared with the control group. (P<0.05) 8. Median survival time was increased about $45\%$ in treatment groups compared with the control group.(P<0.05) 9. Natural killer cell activity was increased in B16F10 lung cancer model, but it was not in sarcoma-180 abdomen cancer. 10. In interleukin-2 productivity test, treatment groups didn't show significant change in lung cancer and abdomen cancer, compared with the normal group.(P<0.005) 11. In making an examination of metastatic cancer with the naked eye, melanoma metastasized in the Lung of C57BL/6 mice. The treated group showed more Melanoma than the control in the numbers and volume.

This study was designed to investigate the associations of the percent body fat dietary intake, plasma lipoprotein profile, lipoprotein(a), and plasminogen activator inhibitor-1(PAI-1) concentrations of 1982 Korean subjects(men : 1000 and women : 982) between the ages of 40 and 59 years. The dietary assessment consisted of twenty-four hour dietary records and food frequency questionnaires. The subjects were identified into one of the five rating groups of % body fat : lean, underweight, normal, overweight and obese groups. The biochemical assessment included measurements of plasma total cholesterol(TC), HDL-cholesterol(HDL-C), LDL-cholesterol(LDL-C), triglyceride(TG), lipoprotein(a)(Lp(a)), and PAI-1. With respect to the ratio of percent energy intake of carbohydrate : protein : fat of the normal group of the women was 62% : 17% : 20%, respectively. Women apparently had a higher intake of carbohydrates than men(52% : 17 : 20%) did. There was a linear relationship between energy intake and % body fat in both mean and women(with the exception of the underweight group of women). The relationship of % body fat of men to the protein and fat intake was higher than that of the carbohydrate intake. Of the men in the study, intakes of energy, protein and alcohol were positively correlated to % body fat. In women, energy, carbohydrate and protein intake were positively correlated to % body fat, however, the fat, cholesterol and alcohol intake did not show any correlation to the % body fat in women. This study showed that % body fat was positively correlated with plasma TC, LDL-C, PAI-1 levels, and TG, but the % body fat was negatively correlated with plasma HDL-C level in both men and women. These results indicated that the high energy intake of obese or overweight subjects might contribute to several of the biochemical indices fo coronary heart disease(CHD) risk. In conclusion, increased energy intake is associated with overweight or obesity in middle aged Korean people. There was no relationship between % energy intake of fat and % body fat in the study, in middle-aged Korean men and women. The plasma lipid profile and PAI-1 level thought to be the risk factors of CHD were positively associated with percent body fat in middle aged Korean people.

Background: Dietary supplementation of unsaturated fats in ruminants, if not stabilized, can instigate oxidative stress which can have negative impact on production performance and enhance the susceptibility to various diseases. The current study examined the effect of dietary 80 % canola oil and 20 % palm oil blend (CPOB) on serum fatty acids, antioxidant profile and biochemical indices in goats. Thirty Boer bucks (4-5 months old; initial BW, $20.34{\pm}0.77kg$) were randomly assigned to diets containing 0, 4 or 8 % CPOB and fed daily for a period of 90 days. Blood was sampled from the goats on 0, 30, 60 and 90 days of the trial and the serum was analyzed for fatty acids, cholesterol, glucose, total protein, antioxidants and lipid oxidation. Results: Neither diet nor sampling time influenced serum TBARS value, catalase, glutathione peroxidase and superoxide dismutase activities, LDL cholesterol, VLDL cholesterol, triglycerides, glucose and total protein. Goats fed 4 and 8 % CPOB had higher (P < 0.05) total cholesterol and HDL cholesterol than the control goats on day 30, 60 and 90. The proportion of C15:0 decreased with increasing level of CPOB on day 30 and 60. Serum C18:1n-9 increased with increasing level of CPOB in diet on day 60. The proportion of C18:3n-3 and C22:5n-3 increased (P < 0.05), while the proportion of C18:2n-6 decreased (P < 0.05) with increase in the level of CPOB on day 60 and 90. Dietary CPOB did not affect serum total carotenoid and ${\delta}$-tocopherol but did increase (P < 0.05) ${\alpha}$ and ${\gamma}$-tocopherol. Conclusion: Dietary canola oil and palm oil blend could be supplemented in diets without instigating oxidative stress in goats.

This study examined how the daily administration of dried CP roots affects body-weight gains of mice. An aqueous CP extract (1 g/kg of CP-W) was orally administered to mice on a daily basis for ten weeks, and the mice's body weights and food intakes were measured throughout the period. At the end of the ten-week treatment, murine blood samples were taken and hematological and serum biochemical parameters were examined. The mice's intra-abdominal organs were weighed at necropsy. The treatment of CP-W significantly suppressed the mice's body-weight gain by about 10%. There were no changes to the food intakes of and no observable abnormal clinical signs in any of the animals throughout the experimental period. There were no significant differences between the control and CP-W mice in regards to the hematological and serum biochemical parameters and the organ weights at necropsy. The results demonstrated that the daily administration of CP-W for ten weeks suppresses body-weight gain in mice and does not change mice's food intake or cause any noticeable toxic effects.

This study was conducted to investigate the effect of drinking ion water on the performance, egg quality, and serum biochemical properties of laying hens in a high-temperature environment. A total of 180 laying hens with equal egg production rates were randomly divided into three treatments with five replicates. Treatments were applied from 24 to 27 weeks of age and included the supply of ion water (IW), tap water (TW), and cold water (CW). The results showed that the egg production rate, egg weight, and feed intake of hens were significantly (P<0.01) improved in the IW group compared with those in the TW group but did not differ from those in the CW group. Egg quality parameters such as albumen height, Haugh unit, and eggshell thickness were found to be higher in the IW than in the TW group (P<0.05); however, no significant differences were observed in comparison with the CW group. Serum Ca and P concentrations tended to increase (P<0.10) in the IW group, and serum high-density lipoprotein cholesterol and albumin levels were greater (P<0.05) in response to IW than those to TW. This study provides evidence that the supply of IW can relieve the high-temperature stress during the summer. In particular, because the improved effects of the IW were confirmed to be similar to those of CW, it shows potential as a method to manage the drinking water of hens in the summer season along with the supply of CW.

A drug delivery system (DDS) based on nanoparticles has been used as a mediator to improve the efficacy of a drug by controlling the amount of drug released and delivering it to a target place. Chitosan, which is non-toxic and biodegradable, has good biocompatibility and excellent adsorption, so it can be used as a drug delivery vehicle. Valine, the essential amino acids, helps muscle growth and tissue recovery, and along with other amino acids. It lowers blood sugar levels and increases growth hormone production. In this study, Valine was adsorbed on magnetic chitosan which is capable of drug absorption, and Fe₃O₄-Valine CNPs was prepared through cross-linking with TPP (Tripolyphosphate). And then absorption and release trends of valine were investigated with the Fe₃O₄-Valine CNPs. Fe₃O₄, which has relatively high stability, is used to make the drug carrier magnetic so that the drug can be delivered to a target place. At optimal conditions, the absorption and release tendency of Fe₃O₄-Valine CNP was confirmed by analyzing by UV-Vis through the Ninhydrin test which is the color reaction of amino acids and by measuring the size of the particles, it was confirmed that it is suitable as a drug carrier.

Four-d-old broiler chicks were randomly assigned to 3 groups with 9 replicates (8 birds/cage) under high ambient temperature; birds fed a basal diet (CON), a basal diet supplemented with 0.25% of probiotic complex (LPB, 1 × 10⁶ Lactobacillus plantarum, 1 × 10⁶ Bacillus subtilis, and 1 × 10⁶ Saccharomyces cerevisiae) and 0.5% probiotic complex (HPB). Immediately after 28-d feeding trial, 6 birds having average body weight per group were sacrificed for evaluating the effects of probiotics on antioxidant parameters in the serum, intestine, and liver of birds. As results, serum biochemical parameters of nitrogen components including total protein, albumin, urea nitrogen, and glutathione were unaffected by dietary probiotics. In addition, serum superoxide dismutase (SOD), glutathione peroxidase (GPX), and glutathione S-transferase (GST) activities, and lipid peroxidation (MDA) were not changed by dietary probiotic supplement in birds. In the intestinal mucosa, SOD activity in the HPB group significantly (P<0.05) increased compared with that in the CON and the LPB groups. Lipid peroxidation in the HPB group significantly (P<0.05) decreased compared with that in the CON group. However, there was no statistical difference in GPX, and GST activities in the intestinal mucosa among treatment groups. In the liver, the activities of SOD, GPX, and GST, and the level of MDA were unaffected by probiotic supplement. In conclusion, 0.5% of probiotics significantly increased SOD activity and decreased lipid peroxidation in the intestinal mucosa, suggesting that probiotic complex could be potential to improve the small intestinal antioxidant capacity of bird under high ambient temperature conditions.

The gallbladder(GB) polyps have malignant potential and nowadays are increasing due to the extended use of ultrasonography. Even though there are various reports on the risk of GB polyps, there is few study on the relationship between the presence of metabolic syndrome including serum biochemistry, lifestyle and the development of gallbladder polyps in korean population. The aim of this study is to establish a relationship between the presence of metabolic syndrome including serum biochemistry and the development of gallbladder polyps in korean population. This study conducted on 151 men and 167 women who visited a musculoskeletal hospital in Gyeonggido to have an ultrasound scan of the abdomen from November 2, 2012 to January 31, 2014. They are randomly selected to evaluate the prevalence risk factors were analyzed by comparing various variables between the GB polyp positive and negative. The collected data were analyzed using the personal computer program SPSS version 20.0 for windows. The mean size of the GB polyps was 3.92mm in diameter. Size of GB polyps were less than 10mm in diameter. As to frequency in the people with the GB polyps, the number of patients with the GB polyps was 184(57.9%): the number of metabolic syndrome of them was 114(26.4%); these results showed that risk of the GB polyps got higher at patients with metabolic syndrome. As to the risk of the GB polyps, people with the GB polyps had significantly higher risk than those without the GB polyps, as follows: The risk was significantly 1.061 times higher by weight; 1.186 by BMI; 1.060 by systolic blood pressure; 1.030 by diastolic blood pressure; 1,009 by Total cholesterol; 2.736 by metabolic syndrome; 1.011 by blood sugar on an empty stomach; 1.064 by ESR. The risk factors of GB polyps were found to be weight, BMI, total cholesterol, Triglycerol, Glucose, systolic blood pressure, diastolic blood pressure, ESR and metabolic syndrome. This study has a possibility to be used an indicator to identify the GB polyps, and in the future larger-scale study will have to be conducted to objectify it.

Blood cardioplegia is known as an established cardioplegic solution during open heart surgery. Recently, the Histidine-Tryptophan-Ketoglutarate (HTK) solution has been introduced as a cardioplegia in Korea. This study was designed to compare the myocardial protective effect between the cold blood cardioplegia (CBC) and HTK solution. Material and Method: Forty patients who underwent valve surgery or coronary artery bypass surgery were randomly divided into CBC group (n=20) and HTK group (n=20). The perioperative hemodynamic and clinical data were analyzed. The concentration of CK-MB, Troponin 1 and Lactate from coronary sinus and radial arterial blood were compared for the evaluation of the myocardial damage. The postoperative serial CK-MB levels were measured. Result: The characteristics of preoperative patients were similar in two groups. The hemodynamic parameters and postoperative clinical data were also similar between the two groups. There were no statistical significances between the CBC and HTK group in the difference of biochemical markers: Δ CK-MB (15.3$\pm$26.0 vs 19.3$\pm$14.3), ΔTro-1 (2.4$\pm$4.9 vs 2.0$\pm$2.20), ΔLac (1.6$\pm$1.0 vs 1.9$\pm$2.5). The serial CK-MB levels were not significantly different between the two groups. Conclusion: These results suggested that the myocardial protective effect of HTK solution was similar to cold blood cardioplegia during open heart surgery.

This study was conducted to evaluate the change of nutritional status and to analyze related factors in hospitalized tuberculosis (TB) patients during their hospitalization. The subjects were 398 men patients (mean age: 47.3 ${\pm}$ 14.4 y) who had hospitalized more than 3 months at TB hospital located in Seoul. The anthropometric and blood biochemical indices were measured, and dietary intakes were assessed. At the time of admission the body weight of subjects was about 76% of the average body weight of Korean men with same age, Body mass index (BMI) of subjects was 18.5 kg/$m^2$, and 53.8% of subjects were under weight status. Average level of blood hemoglobin and hematocrit of subjects was lower than the normal value. After 3 months of hospitalization period, the body weight and body mass index were significantly increased compared to admission by 3.9 kg (7.41%) and 1.4 kg/$m^2$ (7.61%)(p < 0.001), respectively. Blood levels of hemoglobin, hematocrit, albumin, and total protein were also significantly increased after 3 months of hospitalization period compared to admission (p < 0.001). The increment in the body weight and blood indices was significantly higher in below 29 years group than over 60 years group (p < 0.05). The increment in the body weight and body mass index was significantly higher in the under-body weight group compared to the normal-body weight group (p < 0.05). In conclusion the body weight and body mass index of subjects were significantly increased after 3 months of hospitalization period, and the age and body weight of subjects at admission were supposed to influence the degree of change in the nutritional status.
