Changes in hematology and serum biochemistry after treatment of recombinant human erythropoietin (rHuEPO, HM10760) were screened in 4 male cynomolgus monkeys (Macaca fascicularis). Four monkeys, composed of a treatment group of HM10760 and a positive control group of $Aranesp^(R}$, were subcutaneously administered at same dose of $100{\mu}g/kg$. Both groups did not show any change in body weights and food consumption for 4 weeks compared with those of pretreatment. Both groups did not show any change in total leukocyte count (WBC) and platelet count, while both groups showed increased platelet distribution width (PDW) percentage in HM10760 group during a period from day 5 to day 59 and in $Aranesp^(R}$ group during a period from day 9 to day 26. Both groups showed increases in red blood cells (RBC), hemoglobin (HGB), and hematocrit (HCT) approximately 10 days after treatment compared with those of pretreatment (day 0). The increased levels of RBC, HGB, and HCT were much higher in HM10760 than in $Aranesp^(R}$ by the increases of $3.2%{\sim}12.5%$ for RBC, $3.8%{\sim}17.1%$ for HCT, and $1.85%{\sim}11%$ for HGB. Both groups showed increases in red cells distribution width (RDW) and reticulocyte (RET) compared with those of pretreatment, showing the highest peak from day 9. The increased level of RET lasted up to day 14 in $Aranesp^(R}$ group, while it lasted up to day 23 in HM10760 group. The increased level of RDW lasted up to day 59, it was much higher in HM10760 by the increase of $10.1%{\sim}17.6%$ than in $Aranesp^(R}$ group. In serum biochemistry, both groups showed a decrease in chloride level compared with those of pretreatment. These findings indicated that HM10760 increased RBC, HGB, HCT, RDW, and RET compared with those of pretreatment, and the increased levels were much higher in HM10760 than in $Aranesp^(R}$.

Many Lactobacillus strains have been promoted as good probiotics for the prevention and treatment of diseases. We engineered recombinant Lactobacillus casei, producing biologically active canine granulocyte macrophage colony stimulating factor (cGM-CSF), and investigated its possibility as a good probiotic agent for dogs. Expression of the cGM-CSF protein in the recombinant Lactobacillus was confirmed by SDS-PAGE and Western blotting methods. For the in vivo study, 18 Beagle puppies of 7 weeks of age were divided into three groups; the control group was fed only on a regular diet and the two treatment groups were fed on a diet supplemented with either $1\times10^9$ colony forming units (CFU)/day of L. casei or L. casei expressing cGM-CSF protein for 7 weeks. Body weight was measured, and fecal and blood samples were collected from the dogs during the experiment for the measurement of hematology, fecal immunoglobulin (Ig)A and IgG, circulating IgA and IgG, and canine corona virus (CCV)-specific IgG. There were no differences in body weights among the groups, but monocyte counts in hematology and serum IgA were higher in the group receiving L. casei expressing cGM-CSF than in the other two groups. After the administration of CCV vaccine, CCV-specific IgG in serum increased more in the group supplemented with L. casei expressing cGM-CSF than the other two groups. This study shows that a dietary L. casei expressing cGM-CSF enhances specific immune functions at both the mucosal and systemic levels in puppies.

Objective: This study compared the safety and efficacy of $Safacto^{(R)}$ versus $xyntha^{(R)}$ in patients with severe hemophilia A. Methods: Thirty-three male patients with severe hemophilia A were randomly divided into two groups. Seventeen patients received $Safacto^{(R)}$ and 16 patients received $Xyntha^{(R)}$ for four consecutive times. The dosage of FVIII was 40-50 IU/kg for each injection. Plasma level of FVIII activity was evaluated before every injection, 15 minutes after the injection and one month after the start of the trial. The rate of factor VIII activity, pain and joint motion were also assessed before and after the treatment. Results: Plasma level of FVIII clotting activity in $Safacto^{(R)}$ and $Xyntha^{(R)}$ were $1.96{\pm}0.5IU/dl$ and $1.63{\pm}0.5IU/dl$ and increased to $88.84{\pm}25.2IU/dl$ and $100.09{\pm}17.8IU/dl$, respectively (P<0.001). Pain score and range of motion improvement were $9.3{\pm}0.9$ and $8.7{\pm}0.1$ in $Safacto^{(R)}$ (P=0.17); and $9.4{\pm}0.8$ and $8.8{\pm}0.3$ in $Xyntha^{(R)}$ (P=0.35), respectively. No allergic or other unfavorable reactions was observed with either of the preparations. Conclusion: This study showed that $Safacto^{(R)}$ has a favorable efficacy and safety profile.

A feeding trial was conducted to evaluate the effects of two different sizes of extruded pellets (EP) ($EP_1$ - 3 mm or $EP_2$ - 5 mm) and a moist pellet (MP) in olive flounder, Paralichthys olivaceus, reared in semi-recirculation system. A total of 450 fish with an average initial weight of $5.0{\pm}0.2g$ (mean ${\pm}$ SD) were fed one of the three experimental diets in triplicate groups. At the end of a 6-week feeding trial, weight gain, specific growth rate, and feed efficiency of fish fed EP diets were significantly higher than those of fish fed MP (P < 0.05). Water quality parameters like turbidity, total ammonia nitrogen, and total phosphorous from tanks of fish fed $EP_1$ and $EP_2$ were significantly lower than those from tanks of fish fed MP. Blood plasma glutamic oxaloacetic transaminase and glucose concentration were significantly higher in fish fed MP diet compared to fish fed EP diets (P < 0.05). Whole body crude protein contents in fish fed EP diets were higher than those from the fish fed MP diet. Whole body amino acid content like threonine, aspartic acid, serine, tyrosine, and cystine were found to be significantly higher in fish fed EP diets than those in fish fed MP diet. In considering overall performance of olive flounder, $EP_2$ diet could be recommended for the successful aquaculture of this important fish species.

Blood test is a useful tool in establishing medical treatment for livestock. It provides information such as disease diagnosis, treatment effects, prognostic judgment, and health status. This study compared the value of erythrocytes and leukocytes among conventional, transgenic miniature, and transgenic conventional pigs aged six months to 24 months. Further, it analyzed the aspects of hematological value changes according to the pigs' ages. As a result, the number of red blood cells (RBC), which include hemoglobin, and hematocrit, and the number of white blood cells (WBC), which include neutrophils, and lymphocyte, were high among transgenic miniature pigs, compared with the conventional and transgenic conventional pigs. Conventional pigs showed similar values of RBC and WBC regardless of transgenesis. In comparing their age, the RBC decreased as the age increased compared with the pigs among all the three groups aged of 6~12 months. On the other hand, WBC and neutrophils showed no significant difference regardless of different ages among all the three groups. However, various counts in RBC and WBC were mostly found to be higher in each age in transgenic miniature pigs than in conventional and transgenic conventional pigs. The results of this study show that the values of RBC and WBC were generally higher in transgenic miniature pigs than in conventional and transgenic conventional pigs. Based on this research, hematological values can be widely used in diagnosing diseases or checking the health status of transgenic pigs that are used as disease models, organ transplant source and alike.

Certain amino acids are essential precursors of a variety of important biomolecules in addition to their major function as protein building blocks. ${\delta}$-Aminolevulinic acid (ALA) is synthesized from the condensed form of succinyl-CoA with glycine after decarboxylation catalyzed by ALA synthase. The objective of the study was to determine the effects of ALA supplementation on growth performance, behavioral characteristics and hematological/immune status in nursery pigs. A total of 144 pigs weaned at 21 d of age were allotted to three dietary treatments representing (-) control (w/o antibiotics; NC), (+) control (w/carbadox at 50 mg/kg; PC), and the treatment group with ALA supplementation (0.05%; TA). Each treatment had 6 pens (replicates) with 8 pigs per pen. Pigs were fed phase 1 (21.9% CP, 1.40% Lys) and 2 (20.6% CP, 1.15% Lys) experimental diets for 3 and 2 wks, respectively. Feed intake and weight gain were measured weekly during phase 1 and at the end of phase 2. At the end of phase 2, blood samples were taken and analyzed using an automated hematology analyzer. Skin color and activity of pigs (48 h) from all pens in each treatment were measured at the second week of phase 2. Growth performance was not affected (p>0.05) by the dietary supplementation of ALA during the 5 wk nursery period. Pigs in the TA (6.46) and PC (6.68) had a higher (p<0.05) number of red blood cells ($10^6cell/{\mu}L$) than pigs in the NC (6.15). Pigs in PC (12.16) had a higher (p<0.05) hemoglobin level (g/dL) than pigs in the NC group (11.29) and the TA group (11.47). Pigs in the TA and PC had darker (p<0.05) and less (p<0.05) yellow skin color than pigs in the NC. Pigs in the PC tended (p = 0.081) to be less active than pigs in the other groups. There were no differences in behavioral characteristics between the NC and the TA. The data suggest that ALA supplementation has no adverse effects on growth performance of nursery pigs. Moreover, ALA supplementation increased red blood cell counts which may be beneficial to pigs.
