One hundred and twenty weanling pigs in experiment 1 (Exp. 1) ($6.91{\pm}0.99kg$; 21 d of age) and Exp. 2 ($10.20{\pm}1.09kg$; 28 d of age) were used in two 42-d and 35-d experiments to evaluate the effect of medium-chain-triglyceride (MCT) on growth performance, apparent total tract digestibility (ATTD) of nutrients and blood profile. In both of Exp. 1 and Exp. 2, the same dietary treatments were utilized as follows : i) negative control (NC), ii) positive control (PC), NC+antibiotics (40 mg/kg Tiamulin, 110 mg/kg Tylosin, and 10 mg/kg Enramycin, iii) MCT3, NC+0.32% (phase 1, 2 and 3) MCT, and iv) MCT5, NC+0.55% (phase 1), 0.32% (phase 2 and 3) MCT. In Exp. 1, the pigs fed MCT5 diets had higher (p<0.05) ADG compared to NC treatment during the first 2 wk. From d 15 to 28, the ATTD of energy was improved (p<0.05) by MCT3 compared to the PC treatment. No effect has been observed on the blood profiles [red blood cell (RBC), white blood cell (WBC), immunoglobulin-G (IgG), lymphocyte concentration] measured in this study. In Exp. 2, the ADG were increased (p<0.05) by the MCT5 treatment than the PC treatment from d 0 to 14. Pigs fed PC treatment diet had lower ADFI (p<0.05) and better FCR (p<0.05) than NC treatment, whereas no differences were shown between MCT treatments and NC or PC treatment from d 15 to 35 and overall phase. The ATTD of DM and nitrogen were improved (p<0.05) by the effect of MCT5 related to the NC and PC treatment at the end of 2nd and 5th wk. The pigs fed MCT3 had higher (p<0.05) energy digestibility than PC treatment. No effects were seen in the blood profiles we measured (WBC, RBC, lymphocyte and immunoglobulin-G). In conclusion, the addition of MCT in the weanling pigs diet can improve the ADG and digestibility during the earlier period (first 2 wks), but had little effect on the blood characteristics.

A total of 96 pigs ($49.23{\pm}3.20$ kg) were used in an 11 wk growth trial to evaluate the effect of fermentable carbohydrate (FC) content on growth performance, apparent total tract digestibility (ATTD) of nutrient, blood profile, and meat quality. The dietary treatments were: i) negative control (NC), basal diet, ii) positive control (PC), NC+antibiotics (positive control diet with 5 ppm flavomycin), iii) PCL, PC-13% lower FC, and iv) NCL, NC-13% lower FC. The growth performance (average daily gain, average daily feed intake, and gain/feed) didn't differ among treatments through the whole experiment. These pigs fed the PCL diet had the greater (p<0.05) apparent total tract digestibility (ATTD) of dry matter than those from PC and NC treatment at the end of the experiment. No differences were observed in white blood cell (WBC), red blood cell (RBC), and lymphocyte concentration among different treatments. After the feeding period, meat samples were collected from the pigs at slaughter. The pigs in NCL and PCL treatments had greater (p<0.05) backfat thickness and lower lean percentage. The color value of loin was higher (p<0.05) in NCL treatment compared to PCL treatment. Also, the NCL treatment had higher (p<0.05) marbling value than PC treatment. The drip loss was depressed by PCL and NCL treatment comapared to NC treatments. The water holding capacity (WHC) was higher (p<0.05) in NC and PCL treatment. In conclusion, the low FC can improve digestibility and meat quality of finishing pigs.

The hemopoietic effects of deer blood (whole blood, blood cell, plasma, respectively) were examined using in vivo rat model. Experimental animals (Sprague-Dawley rat, male, 200 g) were divided into negative control group (injection of saline), positive control group (injection of Sipjeondaebotang) experimental groups (injection of whole blood, blood cell, plasma) and healthy control group. Cyclophosphamide(150mg/kg) was injected into experimental groups, negative and positive control group to induce bone marrow supression. After 8 days, freez dried deer blood (whole blood, blood cell, plasma respectively) and Sipjeondaebotang of 200 mg/kg in dose was administered orally into experimental groups and positive control group, once a day for 3 days (A group) and once a day for 12 days (B group) respectively. And then body weight and organ weight, biochemical profile (ALB, GOT, GPT, PRO, CRE), hematological values (WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT) and CBC differentiation (Neutro, Lymph, Mono, Reticulo) were carried out. Finally, platelets were specially increased in the plasma treated A group and reticulocytes were specially increased in the plasma treated B group.

A 4-year-old spayed female, Yorkshire terrier dog with a history of petechial and ecchymotic hemorrhages on the face, trunk and hind limb was referred to Veterinary Medical Teaching Hospital, Cheju National University. The complete blood count revealed a marked thrombocytopenia ($96{\times}10^3/{\mu}l$). The biochemical profile showed only slightly increased glucose. The coagulation profile such as prothrombin time and activated partial thromboplastin time, was within the reference range. In Giemsa staining, there were no endoparasites like as Babesia spp. on the RBC. This case was diagnosed as a idiopathic thrombocytopenia in a Yorkshire terrier dog. She was treated with prednisone (1 mg/kg BW, IM q 12 h) and cephalosporin (10 mg/kg BW, IM, q 12 h). When rechecked on day 6, the platelet was within reference range ($507{\times}10^3/{\mu}l$) and also petechial and ecchymotic hemorrhages on the body were gradually improved without any complications. The dose of prednisone was decreased to 0.5 mg/kg BW, q 24 h. On day 17, we finished treatment because all the clinical signs, blood and serum chemistry were reference range and platelet count was dramatically increased.

Electroacupuncture (EA) has been reported to increase pain threshold, and to enhance the NK cell activity by up-regulation of IFN-γ and endogenous β-endolphin. For the purpose of understanding the molecular mechanism of EA stimulation, we analyzed the gene expression profile of rat hypothalamus, treated on Zusanli (ST36) with EA, in comparison with control group by oligonucleotide chip microarray (Affymetrix GeneChip Rat Neurobiology U34 Array) and real-time RT-PCR. Sprague-Dawley (S-D) male rats were stimulated at the Zusanli (ST36) acupoint in restriction holder. Simultaneously the control group was given only holder stress without EA stimulation. In order to prove the appropriateness of EA treatment, we measured spleen NK cell activity with standard 51Cr release assay. NK cell activity of EA group was significantly increased comparing to control group. The microarray and PCR results show that EA treatment up-regulates expression of genes associated with 1) nerve growth such as NGF induced factor A and VGF, 2) signal transduction such as 5HT3 receptor subunit, AMPA receptor binding protein and Na-dependent neurotransmitter transporter, and 3) anti-oxidation such as superoxide dismutase and glutathione S-transferase. In addition, the activity of the anti-oxidative enzyme, SOD of hypothalamus, liver and RBC was enhanced compared to that of control. The list of differentially expressed genes may implicate further insight on the mechanism of acupuncture effects.

Fish oil and shortening have been suggested to have opposite effects on cardiovascular disease (CVD). This study investigated the effect of shortening and fish oil on CVD risk factors and aorta histopathology, and the association between risk factors and aorta histopathology. Male Wister rats (n=30) were fed an AIN-93G diet containing 20% fat in the form of fish oil, shortening, or soybean oil for 4 weeks. Total cholesterol (TC), triacylglyceride (TG), and C-reactive protein levels were significantly (P<0.001) lower in the fish oil than in soybean oil and shortening groups. HDL-cholesterol concentrations were significantly different (P<0.001) between groups. In addition, LDL-cholesterol levels were significantly (P<0.001) lower in the fish oil and shortening groups than in the soybean oil group. Insulin and glucose concentrations did not differ among groups. Effect of dietary fat on tissue fatty acid composition significantly differed in abdominal fat and brain compared with RBC, heart, kidney and liver. The aortic wall was significantly (P=0.02) thinner in the fish oil group than in the soybean oil and shortening groups. The aortic wall thickness was positively correlated with TG and TC, but negatively with EPA + DHA levels of all tissues. These results suggested that fish oil had protective effects on aorta histopathology by hypolipidemic action in this rat model.

Hovenia dulcis Thunb (HDT) has been known folk medicine and has been used as therapeutic drug in the treatment of liver disease. Also it has been used as a detoxifying agents for alcoholic poisoning and promoting diuresis. However, there has not been any study on therapeutic effect of Hovenia dulcis extract on $CCl_4$ induced liver and kidney damage in rats. In this study, we report on therapeutic effects of Hovenia dulcis extract on $CCl_4$ induced liver and kidney damage in rats. Rats were divided into four groups of eighteen animals. Control group (DW) was administrated with distilled water 2.5 mL/kg per peritonial administration and then $CCl_4$ group (CCl) was administrated $CCl_4$ 2.5 mL/kg per peritonial administration, $CCl_4$+HDT extract group ($CCl_4$+HDT) was administrated HDT extrat (100 mg/kg) after $CCl_4$ 2.5 mL/kg administration, $CCl_4$+Silymarin group ($CCl_4$+Sily) was administrated Silymarin (50 mg/kg) after $CCl_4$ 2.5 mL/kg administration. The complete blood cell (CBC) count of RBC, WBC, PCV, Hb, MCH, MCV, MCHC and blood chemistry profile of AST, ALT, GGT, ALP, Total choloesterol, Tryglyceride, Total bilirubin, Amylase, Glucose, BUN, Creatinine, Lipase and pathologic changes were observed for 7 days after administration of D.W., $CCl_4$, $CCl_4$+HDT extract, $CCl_4$+Silymarin. The results are as follows : 1. RBC and PCV were significantly (p < 0.01) increased in all groups compared to D.W. but hemoglobin, MCH, MCV and MCHC were not showed significant difference during experimental periods. 2. AST, ALT, T-cholesterol, T-bilirubin, TG were significantly (p < 0.05) increased in all groups on day 3 compared to D.W. and were normal on day 7. 3. ALP was significantly (p < 0.05) decreased in $CCl_4$+HDT group on day 3 but Amylase was not showed significant difference during experimental periods. 4. BUN was significantly (p < 0.05) increased in $CCl_4$ group on day 7, but $CCl_4$+HDT group and $CCl_4$+Sily group were normal. Creatninie was significantly (p < 0.05) increased in $CCl_4$ group on day 3 and normal on day 7 but $CCl_4$+HDT group and $CCl_4$+Sily group were not showed significant difference during experimental periods.

Objectives : The aim of this study was to evaluate the distribution of tongue color and the correlation of the tongue colors with clinical laboratory parameters. Methods : Statistical analysis on the frequency of each tongue color and the results of the clinical laboratory parameters in each tongue color group. Results : Tongue colors that appeared most frequently were 702c, 695c, 493c, 694c, 701c, 500c, 7432c, 7431c, 7634c, 7419c in that order. Following them, 494c and 507c were rarer colors, and 501c, 673c, 687c, 693c, 696c, 703c, 7418c were equally rarest colors. Among each tongue color group, a significant difference was found in the result of complete blood cell count (CBC). The level of red blood cell (RBC) of 7432c group was significantly higher than that of the other groups except 694c group. The level of hemoglobin (Hb), hematocrit (Hct) of 7432c group were significantly higher than those of all the other groups. The level of RBC of 7431c group was lowest and significantly different from 694c, 7432c group. In results of the other tests were not significantly different. However the level of total cholesterol was higher in 695c, 694c, 500c group, and the level of triglyceride was higher in 500c, 7431c, 694c group. Those four colors have a low chroma and 7431c, 695c take blue violet color. Conclusions : The tongue color is distributed throughout following colors by order of frequency: 702c, 695c, 493c, 694c, 701c, 500c, 7432c, 7431c, 7634c, 7419c, 708c, 494c, 507c, 501c, 673c, 687c, 693c, 696c, 703c, 7418c. Some parameters of CBC has a significant correlation with some tongue colors. Other results including lipid profile, renal function test, and liver function test had no significant difference according to tongue color. However, the colors which have low chroma or take blue violet color tented to be higher in the levels of total cholesterol and triglyceride.

This pilot study aimed to investigate the effects of regional and seasonal variations on the prevalence of Theileria orientalis and the hematological profile of non-grazed dairy cows in Korea. A total of 365 clinically healthy lactating Holstein Friesian cows from 26 dairy farms in 7 provinces that were categorized into northern, central, and southern regions were sampled during the warm period from July to August and the cold period from October to December. The detection of T. orientalis major piroplasm surface protein gene and the hematology non-grazed dairy cows were analyzed using peripheral blood samples. The T. orientalis prevalence was 20.0% (73/365). The prevalence in the southern region was 35.9%, which was significantly higher than that in the central (21.6%) and northern (12.9%) regions (P<0.05). The prevalence during warm period was higher (43.0%) than that during the cold season (13.5%). The infected cows showed significantly lower erythrocyte counts in the southern region (5.8±0.6 M/㎕) and during the warm period (5.8±0.7 M/㎕) compared with those in the central and northern regions and during the cold season, which affected the extended RBC parameters, including hematocrit and hemoglobin concentrations. Our findings revealed the prevalence of T. orientalis in Korea, highlighting its high occurrence during warm periods and in certain geographical regions. Climatic factors could contribute to the health and productivity of cattle, as evidenced by the prevalence of T. orientalis and its negative impact on animals.
