Korean native cattle (Hanwoo) have a good capacity to produce heavily marbled meat of high value. The intramuscular fat in Hanwoo is known to be deposit from 12 months of age by degree of slightly visible and significantly developed in 28 months of age. Lipogenesis gene expression profiling in longissimus dorsi at early and late fattening stage will be helpful to understand the mechanism of intramuscular fat deposition in skeletal muscle. Therefore, we analysed the gene expression patterns of six genes related lipid metabolism (FABP4, GLUT4, LPL, ACC, ACL and SCD) between early and late fattening stage. The mRNA expression of FABP4 at late fattening stage (27 months old) was higher about 3.0 fold than at early fattening stage (12 months old) in each three individuals of Hanwoo. However, GLUT4 mRNA expression was not different at late fattening stage compared with at early fattening stage. On the other hand, The expression patterns of LPL, ACC, ACL and SCD genes related lipid metabolism were significantly over-expressed about 3.5 fold, 2.7 fold, 3.7 fold and 7.5 fold at late fattening stage, respectively. Thus, these results suggested that lipogenesis in skeletal muscle at late fattening stage is due to increasing uptake of fatty acid by FABP4 and lipogenesis gene expression such as LPL, ACC, ACL and SCD.
Objectives: We evaluated the effects of an allergy control program on children with atopic dermatitis (AD) in five schools located within Gyeonggi-do. Methods:Based on the results of the 12-month prevalence of AD symptoms from an International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire of all students (n=2109; 1040 boys, 1069 girls) at five randomly selected schools, 227 students with AD symptoms were screened. Finally, 188 students with greater than 1 on SCORAD (SCORing Atopic Dermatitis) determined by a physician were selected. The allergy control program includes education related to allergic diseases, skin prick tests, and SCORAD evaluation, as well as keeping a daily journal to check the usage of moisturizer at least once a day. To determine the effectiveness of the allergy control program, SCORAD evaluation was performed again six weeks later. Results:The most common symptom for 12-month prevalence was rhinorrhea (33.9%), followed by atopic skin lesions (14.8%) and wheezing (4.0%). The 12-month prevalences of the three allergic diseases were higher for boys than for girls, and a significant difference was found for allergic rhinitis (P<0.001). The mean SCORAD index decreased significantly from 26.1 to 17.5 after the completion of the six-week control program (P<0.01). In particular, these differences were more pronounced for the group which used the daily journal (P<0.001). Conclusions:Our findings indicate that the allergy control program including usage of a daily journal as well as regular monitoring could be a promising tool for preventing and alleviating the symptoms of allergic diseases.
