To examine the effects of vaccination against Babesia gibsoni(B gibsoni) infection in dogs, 15 normal mixed-breed dogs(5 months to 1 year old) were divided into 3 groups with 5 dogs in each group. One of them was selected as control group(group A) and other were selected as experimental groups(group B and C). The group B was vaccinated with antigen which were mixed 0.2% of formalin treated B gibsoni and sonicated one. The group C was inoculated Theileria sergenti as a non-specific antigen. The results obtained in this experiment were summarized as follows; 1. After first vaccination, antibody titers of group B and C were increased 5 times(1:200) than those of control group(1 : 40). The antibody titers of group C were increased more than that of group B after second vaccination. When challenged with the living protozoa(Babesia gibsoni), the antibody titers of C group were elevated higher than that of B group and maintained steadly. Those were not exceeded over 1 : 5,000 for 4 weeks in all 3 groups. 2. After challenge, the peak time of the parasitemia appeared nearly on the 15th day(12~18 days) in all groups. During this period, the rate of parasitized erythrocytes in control group was $55.0{\pm}5.4$‰. But that of group B and C were $41.3{\pm}38.8$‰ and $15.2{\pm}16.3$‰, respectively. 3. After challenge with B gibsoni, all of the values of PCV, Hb, RBC and total leukocytes counts were decreased in both of the experimental and the control. 4. In all groups, there were increased lymphocytes and monocytes after challenge with the protozoa.

Objective: To evaluate several metabolic changes in patients with differentiated thyroid carcinoma (DTC ) which enhance cardiovascular risk in the western region of Nepal. Materials and Methods: This hospital based case control study was carried out using data retrieved from the register maintained in the Department of Biochemistry of the Manipal Teaching Hospital, Pokhara, Nepal between $1^{st}$ January, 2009 and $31^{st}$ December, 2011. The variables collected were age, gender, BMI, glucose, insulin, HbA1C, CRP, fibrinogen, total cholesterol, triglycerides, HDL, LDL, VLDL, f-T3, f-T4, TSH. One way ANOVA was used to examine statistical significance of differences between groups, along with the Post Hoc test LSD for comparison of means. Results: fT3 values were markedly raised in DTC cases ($5.7{\pm}SD1.4$) when compared to controls ($2.2{\pm}SD0.9$). Similarly, fT4 values were also moderately raised in cases of DTC ($4.9{\pm}SD1.3$ and $1.7{\pm}SD0.9$). In contrast, TSH values were lowered in DTC cases ($0.39{\pm}SD0.4$) when compared to controls ($4.2{\pm}SD1.4$). Mean blood glucose levels were decreased while insulin was increased and HDL reduced ($39.5{\pm}SD4.7$ as compared to the control $43.1{\pm}SD2.2$). Conclusion: Cardiovascular risk may be aggravated by insulin resistance, a hypercoagulable state, and an atherogenic lipid profile in patients with differentiated thyroid cancer.

Experimental radiation nephritis was produced in 15 rabbits by X-irradiation. About $2,000{\gamma}$ (tissue doses) were given to both kidneys of a rabbit in 5 days. Other tissues and organs except both kidneys were protected with 2mm thickened lead plates. 5 weeks after the last irradiation, blood pictures, blood pressures, B.U.N., serum creatinine, Ca, Mg, Fe levels and serum erythropoietin activity of the irradiated rabbits were studied. After finishing above studies, rabbits were sacrificed and both kidneys were removed and examined histopathologically. Same laboratory and pathological studies were performed in 6 control rabbits. In this study, the author obtained following results. 1) Both kidneys of rabbitis with experimental raditation nephritis showed marked histopathological changes, i.e.: renal tubules showed diffuse cloudy swelling, impacted intraluminal hyaline casts and focal precipitations of lime salts on the tubular epithelium. Diffuse interstitial fatty necrosis and various degrees of fibrotic infiltrations on the interstitium were also seen in association with focal lymphocytic infiltrations. Hyaline degenerations were observed on the glomeruli and small vessels. 2) Experimental radiation nephritis rabbits showed marked lowering in R.B.C. counts, decreased hemoglobin levels, low hematocrit values and leucopenia in comparison with those of control rabbits. (P<0.01). (Table 1 & 2). 3) Mild proteinuria were observed in experimental radiation nephritis in rabbits. 4) The levels of B.U.N. and serum creatinine increased in experimental radiation nephritis. (P<0.01). (Table 1,3 & 4) 5) The levels of serum Ca and Mg Showed no statistical difference in comparison with those of control rabbits. (P>0.05) (Table 3 & 4). 6) No statistical correlations were observable between the levels of B.U.N. and Hb. values. (${\gamma}=-0.223$) No close correlations (${\gamma}=-0.328$) were noticed between the levels of B.U.N. and serum iron levels. 7) Erythropoietin activity (R.B.C. $^{59}Fe$ Incorporation) was measured by the modified Fried method. No change in its activity was noticed in radiation nephritis group comparing with that of the control group. (P>0.05). (Table 1,3 & 5). 8) Carotid artery blood pressures showed also no difference. (P>0.05). (Table 1 & 2).

Bacillus stearothermophilus No.236 xylB 유전자가 삽입된 재조합 플라스미드 pKMG12를 가지고 있는 E. coli HB101 균주를 이용하여 B. stearothermophilus $\beta$-xylosidase B을 생산, 정제하고 효소의 일반특성을 조사하였다. Ammonuim sulfate 분획, DEAE-Sepharose CL-6B 이온 교환 크로마토그래피, Sephacryl S-200 및 Superdex 200HR 젤 크로마토그래피의 과정을 거쳐 정제하였으며 정제된 효소는 SDS-PAGE 및 zymogram 실험을 통해 $\beta$-xylosidase B의 단백질임을 확인하였다. 정제 $\beta$-xylosidase B는 반응액의 수소이온 농도와 온도에 매우 민감하며 최적 활성 pH 및 온도는 각각 pH 6.5와 $50^{\circ}C$로 결정되었다. $\beta$-Xylosidase 활성은 1 mM $Mn^{2+}$ 첨가에 의해 약 35% 활성화됨을 보였으나 $Ag^{+}$, $Cu^{2+}$ 및 $Hg^{2+}$ 등의 중금속이온의 존재하에서는 거의 완전한 저해를 나타내었다. 또한 본 효소는 비록 높지는 않으나 $\alpha$-arabinofuranosidase 활성도 가지고 있어 B. stearothermophilus No 236의 $\beta$-xylosidase A 효소 보다 최소한 arabinoxylan의 분해에 있어서 더 우수한 효소로 판단되며 o-nitrophenyl-$\beta$-D-xylopyranoside 기질에 대한 $K_{m}$ 값과 $V_{max}$ 값은 각각 6.43 mM과 $1.45\mu$mole/min 로 계산되었다. 한편, $\beta$-xylosidase B 분자량은 gel 여과법으로는 약 160 kDa, 그리고 SDS-PAGE에 의해서는 약 54 kDa로 측정되어 본 효소는 trimer의 구조를 가지고 있음을 알 수 있었다.

Although Korean patients with type 2 diabetes mellitus (T2DM) are generally treated by western medicine, many of them strongly believe in the traditional oriental Sasang constitutional classification and depend on it for food, health supplements, and oriental medicines decision making. Sasang constitutional classification is a part of traditional Korean medicine that divides people into four constitutional types (Tae-Yang: TY, Tae-Eum: TE, So-Yang: SY, and So-Eum: SE), which differ in inherited characteristics such as appearance, personality traits, susceptibility to diseases, and drug responses. It is recommended for T2DM patients to control their blood glucose very well from early stages with drugs and diet. However, many T2DM patients respond differently to their drugs, even though they receive the same medicine. Therefore, the present study investigated whether Sasang constitutional type can explain the therapeutic differences between oral hypoglycemic agents (OHAs) therapy (mono, dual and triple drug therapy). Patients of 618 with T2DM diagnosis and Sasang constitutional type known who received both western and oriental medicine treatment in a hospital between April 2006 and April 2013 retrospectively studied. HbA1c (%) and blood glucose (mg/dl) levels before OHAs therapy and 3 month after were collected for metformin (MET) or sulfonylurea (SU) monotherapy, MET+SU dual therapy, MET+except SU (where was either alpha-glucosidase inhibitor, dipeptidyl peptidase-4 inhibitor, meglitinide or thiazolidinedione) dual therapy, and triple therapy, according to Sasang constitutional type. For statistical analysis, ANOVA was used and paired t-test by SPSS 19.0 where P values less than 0.05 were considered statistically significant. Pattern was similar levels of HbA1c and blood glucose and which was decreased in order of mono, MET+SU dual, MET+except SU dual and triple therapy. In all patients comparison, for the So-yang (SY) constitutional type, either monotherapy was less effective; for Te-eum (TE) type, MET+SU dual therapy was less effective while MET+except SU dual therapy was more effective and the triple therapy was less effective; and for So-eum (SE) type, the triple therapy was more effective. For the management of TE type it is recommended to use drugs except SU when dual therapy is needed, restrict triple therapy and consider dual and insulin therapy; for SY type it is recommended to follow current guidelines; and for SE type it is advisable to skip dual therapy and start the triple therapy early. Finally, the therapeutic response to OHAs is different among Korean T2DM patients with different Sasang constitutional types. Taken together, the choice of effective OHAs therapy for each type is necessary in order to minimize the poor control of blood glucose level, the risk of complications, and the costs from a failure of therapy.

The purpose of this study was to evaluate the changes and readjustment capacity in the hematological characteristics of the horse during and after a prolonged training program. One pony and two hot-blooded horses were used in this study. Resting or basal blood parameters were assessed by collecting blood samples of the animals for 1 to 2 months prior to start of the training program. Each animal was subjected to arbitrary exercise for 30 min by an automatic hot trotter and was bled at 0, 15, 30, 45 (15 min of recovery), 60 (30 min of recovery), and 75 min (45 min of recovery) after onset of exercise. All animals were exercised 3 times a week over a fivemonth period. Hematological parameters including average white blood cell counts (WBC, ${\times}$$10^3$/$\mu$l), erythrocyte concentrations (RBC, ${\times}$$10^6$/$\mu$l), hematocrit (HCT, %), mean corpuscular volume (MCV, fl), number of platelets (PLT, ${\times}$$10^4$/$\mu$l), hemoglobin concentration (Hb, g/dl), mean corpuscular hemoglobin (MCH, pg), and mean corpuscular hemoglobin concentration (MCHC, g/dl) were analyzed using an automatic cell counter. All animals showed that RBC, WBC, and HCT were significantly (p<0.05) increasing from 7.09, 8.55, and 43.5 to 8.11, 9.67, and 49.5, respectively, during the 30 min of exercise and were back to or lower than the initial basis (resting and 0 min) 30 min after exercise. However, no significant differences were detected in MCV (50.3-51.3 fl), MCH (17.2-17.4 pg), and MCHC (33.7-34.4 g/dl) values (p>0.05) regardless of the training periods. Similar trends were observed after 1, 3, 4, and 5 months of training when compared to the resting state. When these parameters were analyzed by the effect of training periods (month), mean WBC concentrations significantly reduced in the fourth and fifth month after onset of training compared to that in resting condition or the first month of training program (p<0.05). The RBC values elevated at the second month (9.40) and reaching a significantly low level (p<0.001) at the fifth month (8.62) after training compared to the first month of training (7.89). In conclusion, a mild training program enhances blood parameters gradually in both the horse and the pony. Therefore, an optimized training program is beneficial in promoting the endurance performance of the horse.

Acetyl xylan esterase was produced by E. coli HB101 harboring a recombinant plasmid pKMG6 which contained the estI gene of Bacillus stearothermophilus. The maximum production was observed when the E. coli strain was grown at 37$\circC for 12 hours in the medium containing 0.5% acetyl xylan, 1.0% tryptons, 1.0% sodium chloride, and 0.5% yeast extract. The esterase produced was purified to homogeneity using a combination of ammonium sulfate fractionation, DEAE Sepharose CL-6B ion exchange chromatography and Sephacryl S-200 gel filtration. The native enzyme had an apparent molecular mass of 60 kd and was composed of two identical subunits of 29 kd. The N-terminal amino acid sequence of the polypeptide was Ala-X-Leu-Gln- Ile-Gln-Phe-X-X-Gln. The acetyl esterase displayed a pH optimum of 6.5 and a temperature opti- mum of 45$\circC. The heavy metal ions such as Ag$^{++}$, Hg$^{++}$ and Cu$^{++}$ inhibited nearly completely the activity of the esterase, and no specific metal ion was found to be required for the enzyme activity. The enzyme readily cleaved MAS, $\beta$-D-glucose pentaacetate, $\alpha$-naphthyl acetate, $\rho$-nitrophenyl acetate as well as acetyl xylan, but had no activity on $\rho$-nitrophenyl propionate, $\beta$-nitrophenyl butyrate or $\beta$-nitrophenyl valerate. The Km and Vmax values for MAS were 2.87 mM and 11.55 $\mu$mole/min, respectively. Synergistic behavior was demonstrated with a combination of xylanase and esterase from B. stearothermophilus in hydrolyzing acetyl xylan.
