Objective: The aim was to evaluate carcass characteristics, cut yield, and meat quality in lambs that were fed different inclusion levels of palm kernel cake. Methods: Forty-five woolless castrated male Santa $In{\hat{e}}s$ crossbred sheep with an initial average body weight of $23.16{\pm}0.35kg$ were used. The experimental design was a completely randomized design with five treatments, with palm kernel cake in the proportions of 0.0%, 7.5%, 15.0%, 22.5%, and 30.0% with nine replications per treatment. After slaughter, the gastrointestinal tract was weighed when it was full, after which it was then emptied. The heart, liver, kidney, pancreas perirenal fat were also collected and weighed. The carcass was split into two identical longitudinal halves and weighed to determine the quantitative and qualitative characteristics. Results: The empty body weight, carcass weight and yield, and fat thickness decreased linearly (p<0.05) as a function of palm kernel inclusion in the diet. There was no difference (p>0.05) for the rib eye area of animals that were fed palm kernel cake. There was a reduction in the commercial cut weight (p<0.05), except for the neck weight. The weights of the heart, liver, kidney fat, small, and large intestine, and gastrointestinal tract decreased. Nevertheless, the gastrointestinal content was greater for animals that were fed increasing levels of cake. For the other organs and viscera, differences were not verified (p>0.05). The sarcomere length decreased linearly (p<0.05), although an effect of the inclusion of palm kernel cake was not observed in other meat quality variables. It is worth noting that the red staining intensity, indicated as A, had a tendency to decrease (p = 0.050). Conclusion: The inclusion of palm kernel cake up to 30% in the diet does not lead to changes in meat quality characteristics, except for sarcomere length. Nevertheless, carcass quantitative characteristics decrease with the use of palm kernel cake.

Objectives : Korean traditional acupuncture Theory, Sa-am's 5 phases acupuncture method was originated in 1644-1742, in the middle of the Cho Sun dynasty. This study was to verify the effect of Sa-am Acupuncture Treatment on dysmenorrhea of Women. Methods : The subjects were 49 volunteers who were suffering for dysmenorrhea, employed using Measure of Menstrual Pain (MMP) questionnaire. Subjects were divided into two groups including Sa-am acupuncture treatment group(n=23) and minimal acupuncture treatment group(n=26). They had agreed to take part in tIris experiment, with didn't take any anodyne drugs. In the acupuncture group, subjects were stimulated at $GB_{41}$, $SI_3$, $GL_{66}$, $SI_2$(Small intestine jung-guk) and $SP_6$. In the control group, subjects were needled at $L_{10}$, $S_{40}$, $P_5$, $G_{40}$ points have any effect on dysmenorrhea. A total of 5 acupuncture sessions were performed for each patient depending on the individual menstruation cycle. The MMP score by using 7 questions and the Menstrual Symptom Severity List(MSSL-D) were measured before and after menstruation cycle. Collected data were analyzed as frequency, percentage, paired t-test, independent t-test using SPSS 10.0 WIN Program. Results : Acupuncture treatment produced a significant improvement on dysmenorrhea in two groups, but a statistically significant difference was not shown in the acupuncture group compare to control group. Conclusions : Based on the above results, it was verified that Acupuncture Treatment was effective in decreasing the symptom of Dysmenorrhea.

4년령 중성화한 수컷 시츄견이 우안에 녹는 궤양이라는 기왕력으로 전북동물의료센터에 내원했다. 안과 검사결과 우안에 각막 전체의 70%에 해당하는 각막 연화를 동반한 각막 천공이 관찰되었다. 또한 홍채 탈출과 섬유소 응괴가 각막 천공 중앙부에서 관찰되었다. 좌안의 위협 반사와 대광 반사는 정상이었다. 각막 결손 부위가 너무 컸기 때문에 각결막 판을 이용한 방법이나 각막 직접 봉합을 배제하였으며 말양막이식술을 시행하기로 결정했다. 말양막은 각막 윤부에 전체 각막을 다 덮을 수 있도록 9-0 나일론 봉합사를 이용하여 봉합을 실시했다. 양막이식 후 79일 째 육아조직과 색소침착이 다소 남아있었으나 우안의 위협 반사와 눈부심 반사는 모두 정상이었다. 비록 색소 침착과 육아조직이 각막에 남아있기는 했지만 개에서 말양막이식술은 녹는 궤양으로 기인한 각막 천공에서 시행해 볼 수 있는 유용한 치료법으로 생각된다.

Objectives Eyes, one of visual inspection regions, present important clues to pathological patterns including deficiency and excess patterns to the clinicians. The purpose of this study was to develop Eyes Inspection Questionnaire (EIQ) and to examine which items among the EIQ were more predictive of clinicians' determination for the deficiency and excess patterns. Methods Nine questionnaire items for Visual Inspection of Eyes were extracted through the literature review. These items were presented to the 4 Korean medical doctors who are specialized in visual inspection to conduct the Delphi method. The Korean medical doctors were asked to rate the importance of each items for the corresponding Visual Inspection of Eyes, using a Likert 5-point scale(the 3 points of importance as a cut-off point). Then, out of 75 photographs submitted to the Society of HyungSang Medicine in 2009, 30 portrait pictures were selected as samples. The samples were copied to make 60 sample pictures, and then randomly assigned to 4 clinicians. The 4 clinicians evaluated the 60 samples for excess and deficiency of the eyes and were asked to check the 6 questionnaire items. The results were recorded as 5-points-scale, and their average and standard deviations were calculated. Intra- class reliability test and multi regression test were performed using SPSS 13. Results Intra-class correlation coefficient (ICC) was between 0.750 to 0.841 (P<0.05). Indices for visual inspection of the eyes were: endowment of the bone structure around the eyes; brightness of the eyes; upward deviation of the eyes; eye shapes; and definition of iris. 76.92% of deficiency symptom patterns and 86.42% of the excess symptom patterns matched the patterns predicted by the visual inspection of the eyes, according to the frequency analysis. According to the multiple regression analysis, were significantly related to the excessive symptoms, and to the deficiency symptoms. Conclusion This study is the first attempt of development for checklist of excess and deficiency of Visual Inspection of Eyes and quantitative measurement of excess and deficiency using the Visual Inspection of Eyes by the visual inspection experts. Still, additional studies are needed regarding the relationship visual inspection methods have with existing standards of diagnosis.

Mycobacterium tuberculosis produces mycolic acids which are relevant for persistence, recalcitrance to antibiotics and defiance to host immunity. c-di-GMP is a second messenger involved in transition from planktonic cells to biofilms, whose levels are controlled by diguanylate cyclases (DGC) and phosphodiesterases (PDE). The transcriptional regulator dosR, is involved in response to low oxygen, a condition likely happening to a subset of cells within biofilms. Here, we found that in M. bovis BCG, expression of both BCG1416c and BCG1419c genes, which code for a DGC and a PDE, respectively, decreased in both stationary phase and during biofilm production. The kasA, kasB, and fas genes, which are involved in mycolic acid biosynthesis, were induced in biofilm cultures, as was dosR, therefore suggesting an inverse correlation in their expression compared with that of genes involved in c-di-GMP metabolism. The relative abundance within trehalose dimycolate (TDM) of α-mycolates decreased during biofilm maturation, with methoxy mycolates increasing over time, and keto species remaining practically stable. Moreover, addition of synthetic c-di-GMP to mid-log phase BCG cultures reduced methoxy mycolates, increased keto species and practically did not affect α-mycolates, showing a differential effect of c-di-GMP on keto- and methoxy-mycolic acid metabolism.
