The polypeptide patterns of cellular and follicular components were analysed by SDS-PAGE and two dimensional(2-D)electrophoresis combined with isoelectric focusing (IEF) to establish protein profiles in each of the components in porcine follicles. Oocyte-cumulus complexes were cultured in M16+FCS+Gn at 39 in an atmosphere of 5% CO$_2$, in air for 35 h. At the end of the culture, the zona-free oocyte, ZP alone and cumulus cells were prepared and analysed either on 10% SDS-PAGE for the protein profile at the first dimensional gel or 2-D protein pattern. The amounts of each samples were determined for the visualization with Coomasie brilliant blue (CBB) or silver staining, thus giving useful information for the identification of specific proteins in the components or appropriate amount of samples for proper visualization. Oocyte showed 25 and 114 kd major protein band. Other minor components were additionally visualized with CBB on the same gel after silver staining procedure. Cumulus cells also showed specific proteins which is not present in the oocytes. The number of cumulus cell was proper to give major bands with CBB and additional minor bands with silver staining. To establish the degree of contamination from the remnant of the corona radiata to the ZP, zonae were differently prepared or analysed by SDS-PAGE.The preparation of the ZP in this study did not showed any contamination judged by the protein profile of the components. Also follicular fluid showed its specific protein profile without any significant differences among the different sizes of follicles. The established protein profile of each follicular component should be helpful for the identification and elimination of contaminated components, i. e., antigen preparation or immunological studies. The results also suggest that the preparation of each components in the study was appropriate and can be used for a further sensitive biochemical analysis in mammalian oocytes and early embryos.

A study was conducted to monitor the changes in serum protein profile, cholesterol and blood glucose during endotoxic shock in buffalo calves and also to assess the role of prophylactic supplementation of vitamin E and selenium in alleviating the endotoxic effects. Fifteen male buffalo calves (6-8 months of age) were divided into three groups: Group I (control)-infused with 0.9% saline solution; Group II-infused with E. coli endotoxin at 5${\mu}g/kg$ body weight in normal saline solution; Group III- supplemented prophylactically with 250 mg vitamin E and 7.5 mg selenium by i/m injections at weekly intervals for one month prior to the induction of endotoxic shock. The blood samples were collected at 0, 1, 3, 6, 9, 12, 24, 48 and 72 h after the induction of shock. Endotoxin caused a significant (p<0.05) hypoproteinemia from 3-12 h post infusion in group II but this hypoproteinemia was less pronounced and only from 3-9 h post infusion in vitamin E and selenium supplemented calves. Hypoglycemia was observed in group II from 3-24 h and blood glucose level returned to normal at 72 h. However hypoglycemia was mild in group III and blood glucose returned to normal at 48h. Hypocholesterolaemia and hypoalbuminemia were found in both groups II and III but these changes were less pronounced in group III i.e. vitamin E and Se supplemented calves. Serum electrophoretic protein patterns of group III were quite similar to those of control group but animals of group II had different electrophoretic pattern. It was concluded that the antioxidant effects of vitamin E and Se prevent the liver against oxidative stress during endotoxic shock.

Thirty new born crossbred (Bos taurus${\times}$Bos indicus) calves, divided randomly in a $3{\times}2$ factorial design, were fed calf starters containing one of three protein sources i.e., groundnut cake (GN), cottonseed meal (CS) and meat and bone meal (MB) along with either raw (M) or gelatinized maize (MG) for 90d. Milk was fed upto 56d of age. Green oats and respective calf starters were offered from 14d of age onwards ad lib. Clinical profile of serum suggested significantly (p<0.05) higher albumin and lower alanine aminotransferase activity due to CS feeding. Alklaine phosphatase activity varied significantly (p<0.05) among dietary treatments showing interaction between protein and starch sources. Inclusion of gelatinized maize resulted in significantly higher concentration of serum globulin (p<0.05) and alkaline phosphatase activity (p<0.01). reduced (p<0.05) ruminal pH was accompanied by a significant decrease (p<0.01) in $NH_3-N$ concentration in the strained rumen liquor (SRL) of MG fed calves. Ruminal amylase activity was lower (p<0.05) on MG diets. Alanine aminotransferase activity in the rumen exhibited a significant (p<0.01) interaction between protein and starch sources. While feeding of CS significantly (p<0.01) reduced alanine aminotransferase activity, inclusion of thermally processed maize reduced (p<0.01) both aspartate and alanine aminotransferase activities in the rumen. The overall blood picture was similar among treatments, whereas rumen metabolites especially enzyme activities, seems to be altered with source of degradable protein an starch.

Objective: This study was conducted to investigate the effect of dietary onion (Allium cepa) extract (OE) supplementation on growth performance, apparent total tract retention (ATTR), blood profile, carcass characteristics and meat quality in broilers. Methods: Four hundred male broiler chicks (Ross 308, 3-d old) were randomly allocated to four dietary treatments for 28 d feeding trial. Each treatment has five replications with 20 birds each. Four dietary treatments were designated according to the OE supplementation levels (0 as control, 5, 7.5, and 10 g of OE per kg of basal diet respectively). On d 28, a total of 20 birds from each treatment were subjected for ATTR, serum biochemical assay, carcass characteristic and organ weight measurement. Results: Overall weight gain of OE 7.5 g/kg group was higher (p = 0.04) than control group. The ATTRs of dietary energy (p<0.01) and ether extract (p = 0.04) linearly increased with increasing levels of dietary OE. However, no difference in ATTR of dry matter and crude protein was evident. Furthermore, serum IgG concentration increased linearly (p<0.01) and quadratically (p = 0.03) with increasing OE supplementation. No differences in carcass dressing weight and amount of abdominal fat by treatments were observed. Also, the weight of organ including immune organ was not different among the treatments. The TBARS values of 10 d stored breast meat decreased linearly (p<0.01) and quadratically (p<0.01) with increasing dietary OE levels. The meat color was also affected, with lower (p<0.01) redness score in meats from OE supplemented groups. This study showed that dietary OE improved broiler weight gain presumably by increasing feed intake and ATTR of both energy and ether extract. The dietary OE increased serum IgG level and meat anti-oxidation capacity. Conclusion: This study implies that the recommended level of dietary OE supplementation could be beneficial for improving broiler performance and meat quality.

Liver function tests were peformed in 61 vivax, 54 malariae and 15 ovale malaria patients who were admitted to Bangkok Hospital for Tropical Diseases between 2001 and 2004. The objective of the study was to evaluate changes in hepatic biochemical indices before and after treatment with artemisinin derivatives. On admission and prior to treatment, hepatic dysfunction was found among the 3 groups. Serum liver function tests and physical examinations were peformed weekly during the 28-day follow-up period. Initially elevated serum bilirubin and diminished albumin returned to normal within 2 weeks of treatment. Serum alkaline phosphatase and aminotransferases returned to within normal limits within 3 weeks. We conclude that patients with Plasmodium vivax, P. malariae and p. ovate infections had slightly elevated serum bilirubin, aminotransferase and alkaline phosphatase levels, and hypoalbuminemia. These minor abnormalities returned to normal within a few weeks after treatment with therapies based on artemisinin derivatives.

The purpose of this research was to examine the relationship between the plasma LDL particle size and blood lipid profile, dietary factors and anthropometric values (body mass index, waist circumference and waist/hip ratio). The subjects were 173 adults aged 23 to 81 years, selected from the Outpatient Clinic and Cardiovascular Department of the Seoul Municipal Hospital. Dietary data were obtained using a 3-day food record and analyzed using Korean and US nutrient databases. The subjects were divided into three groups by LDL particle size : type A (large buoyant LDL, > 25.5 nm, n=96), type I (Intermediate LDL,$25.2\leq-\leq25.5$ nm, n=18), and type B (small dense LDL, < 25.2 nm, n=59) groups. The type B group had higher age, waist circumference, and waist/hip ratio (WHR) than the type A and type I groups. Serum concentration of triglyceride, Apo B, LDL/HDL cholesterol ratio and atherogenic index were significantly higher in the type B group as compared to those in the other two groups. HDL cholesterol level and Apo A-I/Apo B ratio were significantly lower in the type B group than the other two groups. The plasma LDL particle size was highly correlated with triglyceride (r= -0.450), Apo B (r= -0.402) and HDL cholesterol (r= 0.418). However, there was no correlation between plasma LDL particle size and dietary intakes. This study showed that small dense LDL was an important biochemical risk factor that was associated with other risk factors.

Botryococcus braunii is a green colonial fresh water microalga and it is recognized as one of the renewable resources for production of liquid hydrocarbons. CFTRI-Bb-l and CFTRI-Bb-2 have been reported for the first time and their performance with regard to growth and biochemical profile is presented here. The present study focused on effect of carbon dioxide $(CO_2)$ on biomass, hydrocarbon, carbohydrate production, fatty acid profile, and carotenoid content in various species of B. braunii (LB-572, SAG 30.81, MCRC-Bb, N-836, CFTRI-Bb-l, and CFTRI-Bb-2) at 0.5, 1.0, and 2.0% (v/v) levels using a two-tier flask. $CO_2$ at 2.0% (v/v) level enhanced growth of the organism, and a two-fold increase in biomass and carotenoid contents was observed in all the B. braunii strains studied compared with control culture (without $CO_2$ supplementation). At 1 % and 2% (v/v) $CO_2$ concentrations, palmitic acid and oleic acid levels increased by 2.5 to 3 folds in one of the strains of B. braunii (LB-572). Hydrocarbon content was found to be above 20% at 2% $CO_2$ level in the B. braunii LB-572, CFTRI-Bb-2, CFTRI-Bb-l, and N-836 strains, whereas it was less than 20% in the SAG 30.81 and MCRC-Bb strains compared with control culture. This culture methodology will provide information on $CO_2$ requirement for growth of algae and metabolite production. B. braunii spp. can be grown at the tested levels of $CO_2$ concentration without much influence on culture pH.

BACKGROUND/OBJECTIVES: Vitamin D plays an important role in the etiology of gestational diabetes mellitus (GDM). This study evaluated the effect of vitamin D supplementation on metabolic indices and hs-C-reactive protein (CRP) levels in GDM patients. SUBJECTS/METHODS: The study was a randomized, placebo-controlled, double-blinded clinical trial. Seventy-six pregnant women with GDM and gestational age between 24-28 weeks were assigned to receive four oral treatments consisting of 50,000 IU of vitamin $D_3$ (n = 38) or placebo (n = 38) once every 2 weeks for 2 months. Fasting blood glucose (FG), insulin, HbA1c, 25-hydroxyvitamin D, lipid profile, hs-CRP, and homeostasis model assessment-insulin resistance (HOMA-IR) were measured before and after treatment. Independent and paired t-tests were used to determine intra- and intergroup differences, respectively. ANCOVA was used to assess the effects of vitamin D supplementation on biochemical parameters. RESULTS: Compared with the placebo group, in the vitamin D group, the serum level of 25-hydroxyvitamin D increased (19.15 vs. -0.40 ng/ml; P < 0.01) and that of FG (-4.72 vs. 5.27 mg/dl; P = 0.01) as well as HbA1c (-0.18% vs. 0.17%; P = 0.02) decreased. Improvements in the lipid profiles were observed in the vitamin D group, but without statistical significance. Significant increases in concentrations of hs-CRP, FG, HbA1c, total cholesterol, and LDL cholesterol were observed in the placebo group. No significant change in fasting insulin and HOMA-IR was observed in either group. CONCLUSIONS: In GDM patients, vitamin D supplementation improved FG and HbA1c but had no significant effects on lipid profile or hs-CRP.

The API STAPH system was compared with conventional methods for identification of 214 strains of Staphylococcus hyicus subsp. hyicus isolated from cases of exudative epidermitis in piglets, skin of healthy pigs, skin of healthy chickens and bovine intramammary infections, and biochemical characteristics among the swine, avian and bovine strains were also compared. All of the swine and bovine strains produced acid within 24 hours from fructose, lactose and trehalose by conventional methods, but some of the avian strains showed a delayed positive reaction in these carbohydrates. These delayed positive strains in conventional methods gave usually negative results for them in the API STAPH system. With the API STAPH system, eighteen different profile numbers were encountered in 214 strains of swine, avian and bovine origin. The swine and bovine strains, respectively, were distributed among 4 profiles, while the avian strains were distributed among 17 profiles. The profile number observed most frequently in the strains of each animal species was uniformly 6 516 153. By conventional methods, approximately 96% of the swine strains were positive for ${\beta}$-glucuronidase, but not in any strains from chickens and cattle. For hyaluronidase production determined by degradation of sodium hyaluronidate in a solid culture medium, all the swine and bovine strains were positive, but only 37.5% of the avian strains were positive for it. From these findings, there were differences in the production of extracellular active substances between swine strains of Staphylococcus hyicus subsp. hyicus and those isolated from chickens and cattle.

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.
