Embryonic stem cells (ESCs), representing a population of undifferentiated pluripotent cells with both self-renewal and multilineage differentiation characteristics, are capable of spontaneous differentiation into cardiomyocytes. The present study sought to define the kinetic characterization of lactate dehydrogenase (LDH) and creatine kinase (CK) of ESC- and neonatal-derived cardiomyocytes. Spontaneously differentiated cardiomyocytes from embryoid bodies (EBs) derived from mouse ESC line (Royan B1) and neonatal cardiomyocytes were dispersed in a buffer solution. Enzymes were extracted by sonication and centrifugation for kinetic evaluation of LDH and CK with spectrophotometric methods. While a comparison between the kinetic properties of the LDH and CK of both groups revealed not only different Michaelis constants and optimum temperatures for LDH but also different Michaelis constants and optimum pH for CK, the pH profile of LDH and optimum temperature of CK were similar. In defining some kinetic properties of cardiac metabolic enzymes of ESC-derived cardiomyocytes, our results are expected to further facilitate the use of ESCs as an experimental model.

Creatine(Cr) and phosphocreatine(PCr), the important mediators of intracellular high-energy phosphate buffer system, were found in the tissues of mouse seminal vesicle and also in the extracellular fluids of seminal vesicle secretion. This study was performed m confirm that the secretion and accumulation of Cr and PCr is regulated by testosterone and its $5{\alpha}$-reduced metabolite, $5{\alpha}$-dihydrotestosterone(DHT). In addition, the effect of nandrolone decanoate(ND), a synthetic anabolic steroid, on the levels of Cr and PCr in the seminal vesicle was compared with those of testosterone propionate(TP) and DHT. Male Swiss-Webster mice were castrated and three groups of the castrates were treated with daily injection(sc) of same molar dose($1.45{\times}10^{-8}mol/g\;BW$) of TP, DHT, or ND. All three androgens rapidly increased weights of seminal vesicle tissue and fluid, and also increased concentrations of Cr and PCr in the tissue and fluid. However, ND was least effective in increasing seminal vesicle weights, whereas ND was as effective as, or in some cases, more effective than, TP or DHT in increasing Cr and PCr levels in the tissue and fluid. The results confirm that the accumulation of Cr and PCr in the seminal vesicles is regulated by testosterone and DHT, and also suggest that the effects of androgens on seminal vesicle growth and secretory activity may be differentiated.

근세포가 분화하는 과정에 있어서 신경전달물질의 역할을 알아보기 위해서 배양중인 근원세포에 dopamine을 처리하고, 융합지수, creatine kinase 합성률 및 dopamine에 대한 차등감수성을 조사하였다. 배양후 34시간된 근원세포에 $3 \\times 10^{-5} M$의 dopamine을 처리하면 그후 전 시기에 걸쳐 융합지수가 크게 감소되며, 이와 더불어 creatine kinase의 합성률도 감소하는 사실로 미우러 이들 사이에 상관관계가 있음을 알 수 있었다. 또한 dopamine의 융합억제효과는 세포주기에 따라 감수성이 달라지는 차등감수성을 관찰할 수 있었는데, 이는 근세포막에 위치할 것으로 생각되는 dopamine receptor의 배치가 세포주기에 따라 달라지는 데 연유되는 것으로 추정되었다.

Objective: This study was conducted to investigate the effects of in ovo feeding (IOF) of creatine pyruvate (CrPyr) on the energy metabolism in thigh muscle of embryos and neonatal broilers. Methods: A total of 960 eggs were randomly assigned to three treatments: i) non-injected control group, ii) saline group injected with 0.6 mL of physiological saline (0.75%), and iii) CrPyr group injected with 0.6 mL of physiologi-cal saline (0.75%) containing 12 mg CrPyr/egg on 17.5 d of incubation. After hatching, 120 male chicks (close to the average body weight of the pooled group) in each group were randomly assigned to eight replications. The feeding experiment lasted 7 days. Results: The results showed that IOF of CrPyr increased glucose concentrations in the thigh muscle of broilers on 2 d after injection (p<0.05). Compared with the control and saline groups, the concentration of creatine in CrPyr group was increased on 2 d after injection and the day of hatch (p<0.05). Moreover, IOF of CrPyr increased the creatine kinase activity at hatch and increased the activities of hexokinase and pyruvate kinase on 2 d after injection and the day of hatch (p<0.05). Chicks in CrPyr group showed higher mRNA expressions of glucose transporter 3 (GLUT3) and GLUT8 on the day of hatch (p<0.05). Conclusion: These results demonstrated that IOF of CrPyr was beneficial to enhance muscle energy reserves of em-bryos and hatchlings.

Objective: This study aims to investigate the interactive effect of a glycine equivalent (Gly_equi) and standardized ileal digestible threonine (SID Thr) levels in low crude protein diets on performance, blood biochemistry, pectoral muscular creatine content and oxidative stability of meat in broiler chickens from 21 to 42 days. Methods: A total of 1,500, twenty-one-day-old Cobb-Vantress male broiler chickens were distributed in a completely randomized 5×3 factorial arrangement of Gly_equi×SID Thr with five replicates of 20 birds each. Fifteen dietary treatments of 16.5% CP were formulated to contain five levels of total Gly_equi (1.16%, 1.26%, 1.36%, 1.46%, and 1.56%) and three levels of SID Thr (0.58%; 0.68% and 0.78%). Results: Interaction effects (p<0.05) of Gly_equi and SID Thr levels were observed for weight gain, carcass yield, pectoral muscular creatine content and serum uric acid. Higher levels of Gly_equi increased (p = 0.040) weight gain in 0.58% and 0.68% SID Thr diets compare to the 0.78% SID Thr diet. The SID Thr level at 0.68% improved (p = 0.040) feed conversion compared to other SID Thr diets. Levels of Gly_equi equal to or above 1.26% in diets with 0.78% SID Thr resulted in birds with higher (p = 0.033) pectoral muscular creatine content. The breast meat yield observed in the 0.68% SID Thr diet was higher (p = 0.05) compared to the 0.58% SID Thr diet. There was a quadratic effect of Gly_equi levels for pectoral pectoral muscular creatine content (p = 0.008), breast meat yield (p = 0.030), and serum total protein concentrations (p = 0.040), and the optimal levels were estimated to be 1.47%, 1.35%, and 1.40% Gly_equi, respectively. The lowest (p = 0.050) concentration of malondialdehyde in the breast meat was found in 0.68% SID Thr diets at 1.36% Gly_equi. Conclusion: The minimum dietary level of Gly_equi needed to improve performance in low crude protein diets is 1.26% with adequate SID Thr levels for broiler chickens.
