This study was conducted to evaluate the effects of dietary Korean red pine bark extract as an antibiotic replacements on cholesterol, fatty acids and the shelf-life of chicken meat. To accomplish this, chickens were fed the optimal level of red pine bark extract that was found to replace antibiotics in the diet of broilers. A total of 180 male broilers(Ross strain 308) were divided into three treated groups, T1(control group), T2(8 ppm of avilamycin) and T3(65 ppm of red pine bark extract per kg diet). The lipid content was reduced by 24.67% and 20.49% in T3 group, while the cholesterol level also decreased significantly in the T3 group by 20.49% and 20.55% when compared to the T1 and T2groups, respectively. In addition, the saturated fatty acid level was lower in the T3 group than in the T1 and T2 groups, while the unsaturated fatty acid level of the T3 group was significantly higher than those of the other groups. The TBARS value of chicken thigh muscle containing its skin on the 7th day of low temperature storage was significantly lower by 23.86% and 21.17% in the T3 group than in the T1 and T2 groups, respectively. Evaluation of the color of the meat revealed that the L*value (lightness) and b*value(yellowness) were higher in the T3 group than in the T1 and the T2 groups, but that the pH was significantly lower in the T3. Based on the results of this study, the addition of 65 ppm red pine bark extract to the diet of broilers should improve their meat quality with respect to the lipid contents and shelf-life when compared to the addition of antibiotics.

BACKGROUND: Kawasaki disease (KD) sometimes presents with only fever and cervical lymphadenopathy before other clinical signs materialize. This lymphadenopathy-first-presenting Kawasaki disease (LKD) may be misdiagnosed as bacterial cervical lymphadenitis (BCL). We investigated characteristic imaging and clinical data for factors differentiating LKD from BCL. METHODS: We compared imaging, clinical, and laboratory data of patients with KD and BCL. We included patients admitted to a single tertiary center between January 2015 and July 2018. RESULTS: We evaluated data from 51 patients with LKD, 63 with BCL, and 218 with typical KD. Ultrasound imaging revealed multiple enlarged lymph nodes in both LKD and BCL patients. On the other hand, computed tomography (CT) showed more abscesses in patients with BCL. Patients with LKD were younger and showed higher systemic and hepatobiliary inflammatory markers and pyuria than BCL patients. In multivariable logistic regression, younger age and higher C-reactive protein (CRP) retained independent associations with LKD. A comparison of the echocardiographic findings in LKD and typical KD showed that patients with LKD did not have a higher incidence of coronary artery abnormalities (CAA). CONCLUSIONS: LKD patients tend to have no abscesses on CT and more elevated systemic hepatobiliary inflammatory markers and pyuria compared to BCL patients. The absence of abscess on CT, younger age, and elevated CRP were the most significant variables differentiating LKD from BCL. There was no difference in CAA between LKD and typical KD.
