  • This study was performed to investigate the changes of the serological lipid-related parameters of the rats when they were fed with the high fat diets supplemented with or without rutin for five weeks. Twenty-four Sprague-Dawley male rats ($272.2{\pm}7.2 g$ of body weight) were randomly divided into three groups: control (C) group and two treatment groups. Rats in the C group were fed with the high-fat diet containing 20% lard, 1% cholesterol and 0.5% sodium cholate (w/w) which was modified from the formula of the American Institute of Nutrition-76 (AIN-76) diet. Rats in treatment groups were fed with above diet supplemented with 0.75% rutin (R-0.75) or 1.5% rutin (R-1.5) on the weight to weight basis, respectively. The supplementation of rutin did not induce any significant difference on the final body weight, gain of body weight, the amount of feed intake and the feed efficiency of rats in both control and treatment groups. In addition the values of glucose concentration, total protein, albumin, globulin and albumin/globulin (A/G) ratio showed no significant differences among groups. The values of total cholesterol (TC) and low density lipoprotein-cholesterol (LDL-C) in sera of rats in both R-0.75 and R-1.5 groups were lower than those in C group but the significances were showed in only between R-0.75 and C group (p < 0.05 and p < 0.01, respectively). The values of high density lipoprotein-cholesterol (HDL-C) in sera of rats in both R-0.75 and R-1.5 groups were higher than those in C group but the significances were showed in only between R-1.5 and C group (p < 0.01). The values of atherogenic index(AI) of rats in both R-0.75 and R-1.5 groups were the lower than those in C group (p < 0.01 and p < 0.05, respectively). The values of triglyceride in sera of rats showed no significant differences among groups. The values of AST and ALT in sera of rats showed no significant differences among groups. Therefore the supplementation of rutin to high fat diet in rats reduced effectively the serum lipid levels such as TC and LDL-C which were regarded as to cause the cardiovascular diseases, and moreover it elevated effectively HDL-C value which was regarded to protect cardiovascular diseases.

  • Objectives : The causative pathology of acute muscular pain cannot be defined in many patients. To evaluate the relations between mental state and acute muscular pain patients, the author surveyed symptom check list-90-Revision(SCL-90-R) in patients with acute muscular pain. Materials and Methods : From November 2004 to June 2005, a questionnaire including SCL-90-R was given to patients(52 persons) who visited our department for acute(<7days)muscular pain of neck(22 persons) or low back(30 persons). Fifty two patients(30 male, 22 female) completed SCL-90-R Results : 1. Mean values of T-scores on all 9 basic scales in the patients groups were within normal range. but T-scores SOM in the patients groups were significantly very higher than those in Normal groups(p<0.01). 2. The T-scores of SOM In low back pain patients were significantly higher than those in Normal groups(p<0.05). 3. There was no significant difference in all scales between acute muscular pain and L-spine HIVD patients groups. 4. There was no significant difference in all scales between acute muscular pain and general back pain patients groups. 5. There was no significant difference in all scales between male and female in the patients groups. Conclusion : It is concerned between T-scores on all 9 bas κ scales of SCL-90-R and acute muscular pain. Especially acute muscular pain of back has a relation to somatization of T-scores on all 9 basic scales of SCL-90-R.

  • In this paper, all rings or (left)near-rings R are associative, and for near-ring R, all R-groups are right R action and all modules are right R-modules. First, we begin with the study of rings in which all the additive endomorphisms or only the left multiplication endomorphisms are generated by ring endomorphisms and their properties. This study was motivated by the work on the Sullivan's Problem [14]. Next, for any right R-module M, we will introduce AM modules and investigate their basic properties. Finally, for any nearring R, we will also introduce MR-groups and study some of their properties.

  • The purpose of this study was to assess the metabolic profile and nutrient intake data in Korean adolescents according to exercise regularity using the forth Korean National Health and Nutrition Examination Survey from 2008 data. A total of 834 Korean adolescents (440 boys, 394 girls) aged 12 to 18 years were classified into exercising male (EM), non-exercising male (NM), exercising female (EF), and non-exercising female (NF) groups. EM exhibited significantly higher weight (P<0.001), waist circumference (WC) (P<0.01) and body mass index (EMI) (P<0.001) than NM. EF showed significantly greater height (P<0.01), weight (P<0.001), we (P<0.001), and BMI (P<0.001) than NF. Although ratios of macronutrient intake were within the appropriate range in all groups, energy, riboflavin, vitamin e and calcium were assessed as in adequate by the nutritional adequacy ratio (NAR) in all groups. Moreover, EF and NF had inadequate intake of vitamin A and iron according to NAR, respectively. There were significant correlations between height and NAR protein (r=0.249, P<0.001), and mean adequacy ratio (MAR) (r=0.177, P<0.01), and between weight and NAR protein (r=0.180, P<0.01), and MAR(r=0.136, P<0.05) in EM. On the other hand, there were significant correlations between weight and NAR protein (r=0.270, P<0.01), we and NAR protein (r=0.271, P<0.01), and BMI and NAR protein (r=0.326, P<0.01) in NM. There were significant correlations height and NAR Fe (r=0.153, P<0.05) in EF. However, there were no significant correlations between metabolic factors and nutritional adequacy in NF. Although we noted no significant differences in MAR between the groups, the exercising groups showed higher MAR values than the non-exercising groups. Therefore, practicing of ideal dietary behaviors appears to be induced through physical activity and regular exercise in Korean adolescents.

  • This study was performed to investigate the effects of recombinant BST formulation treatment on the milk yield, milk components, mastitis, and general cow health condition when the formulations of retinyl palmitate, cholecalciferol and rBST were administered after the peak period of milk production. The milk yields of treatment groups (Group I, II, III and IV) were increased from 21.5% to 29.0% than that of control group. There was significant difference in milk production between treatment group II, IV and control group (P<0.05). However, there was no significant difference in milk production between treatment group I, III and control group (P<0.05). And the addition of retinyl palmitate and cholecalciferol into rBST formulation did not increase the milk yield. The milk of treatment groups with sustained-release rBST did not show significant difference in milk components (milk fat, protein, lactose, and solid not fat). However, there were minor changes, primarily in fat content of milk, during the first few weeks of rBST administration. There was no incidence of clinical mastitis between rBST treatment groups and control group. Addition of high and medium concentration of retinyl palmitate and cholecalciferol into sustained-release rBST formulation was efficient in reduction of somatic cell count in milk. There was great energy deficit in all treatment groups compared with control group during the early study period. Thus, the body condition score of all treatment groups showed lower value than control group. No evidences of metabolic health problems, such as ketosis, milk fever, and downer cow were observed. Incidence of general lameness did not appear on all treatment groups during 140 days of this study.

  • MicroRNAs (miRNAs) are short non-coding RNA molecules characterized by their regulatory roles in cancer and gene expression. We analyzed the expression of miR-21, miR-205, and miR-342 in 59 patients with breast cancer. Samples were divided into three different groups according to their immunohistochemistry (IHC) classification: ER- positive and/or PR-positive group ($ER^+$ and/or $PR^+$; group I); HER2-positive group ($HER^{2+}$; group II); and ER/ PR/ HER2- negative ($ER^-$/ $PR^-$/ $HER^{2-}$; group III) as the triple negative group. The expression levels of the 3 miRNAs were analyzed in the tumor samples and the compared with the normal neighboring dissected tumor (NNDT) samples in all three groups. The expression of miR-21 was similar in all three groups. In patients positive for P53 by IHC, positive for axillary lymph node metastasis and higher tumor stages, it appeared to have significantly elevated. However, significant increase was not found among the 18 fibroadenoma samples. Both miR-205 and miR-342 expressions were significantly down regulated in group III. We conclude that miR-21 does not discriminate between different breast cancer groups. In contrast, miR-205 and miR-342 may be used as potential biomarkers for diagnosis of triple negative breast cancer.

  • As the mechanical property of composite resin improved, composite resin has been widely used esthetic dentistry. In the field of esthetic dentistry, the color of prosthetic material is very important. The purpose of this study was to evaluate the color difference of specimens, by the types of alloys and gold electrodeposit. Experimental groups were as follows : Group Prec : Au-Pt alloy with no gold coating and no resin veneer. Group Semi : Pd-Ag alloy with no gold coating and no resin veneer. Group BAse : Ni-Cr alloy with no gold coating and no resin veneer. Group Gsem : Pd-Ag alloy with no gold coating and no resin veneer. Group Gbas : Ni-Cr alloy with no gold coating and no resin veneer. Group PreR : Resin veneer on the Pd-Ag alloy without gold coating. Group SemR : Resin veneer on the Pd-Ag alloy without gold coating. Group GbsR : Resin veneer on the Ni-Cr alloy with gold coating Group BasR : Resin veneer on the Ni-Cr alloy without gold coating. In this study, colors of metal surfaces and veneered resins were evaluated by the CIE $L^{*}a^{*}b$ system. The results obtained were as follows : 1. different alloy types and gold coating make the $L^{*}a^{*}b$ system. 2. The ${\Delta}E^*$ab value between groups semi and Base was less than 1.5 and there was no $a^*$ and $b^*$ value difference between groups Gsem and Gbas 3. The values of $L^*$ and $a^*$ ain groups GsemR and GbasR were so similar that the ${\Delta}E^*$ab value was as small as 0.58. 4. In resin specimens with gold coated semiprecious or base alloys showed yellower and redder deviation than the resin specimens with precious alloy. 5. The ${\Delta}E^*$ab values between goups PreR-GsemR and groups PreR-GbasR were as small as 2.68 and 2.22 respectively.
