  • Purpose: The purpose of this study was to investigate the effects of 12-week brisk walking and brisk walking plus diet program on C-Reactive Protein(CRP) in middle-aged obese hypertriglycemic($triglyceride{\geq}150mg/d{\ell}$) Korean women. Method: The subjects were 16 obese ($BMI{\geq}25$) hypertriglycemic middle-aged women (7 for brisk walking group, 9 for brisk walking plus diet group) who participated in a health promotion program at one public health center. Initially the brisk walking intervention consisted of walking for 20 minutes/day at an intensity of 40 to 50% of heart rate reserve(HRR) for 3 days/week and progressed to 50 minutes/day, 60 to 70% of their HRR, and 6 days/week. The diet intervention consisted of 60 minutes of group education and 20 to 30 minutes of individual counseling with a nutritionist every week. Data were analyzed with SPSS PC program. Results: There was no significant reduction in CRP levels in both brisk walking (Z=-1.70, p=0.088) and brisk walking plus diet group(Z=-0.31, p=0.752). In brisk walking only group, CRP levels were increased after the intervention. Conclusion: Brisk walking could increase the level of CRP when it is in the course of progression and diet could decrease the acute phase inflammatory response.

  • This study investigated the general status of tube feeding for intensive care unit (ICU) inpatients and evaluated the consequent nutritional status of patients. This study was approved by the Institutional Review Board (IRB) of a general hospital located in Daegu metropolitan city. The subjects of this study were 80 adult patients who had been admitted to the ICU of a hospital, received fed tube feeding, and then been discharged. The differences in nutrition screening indicators, including percentage ideal body weight (PIBW), serum albumin, hemoglobin, total lymphocyte count, and total cholesterol, before and after tube feeding according to body mass index (BMI) or nutrient feeding levels were investigated. The ratios of actually provided amounts to calorie and protein requirements of patients were $72.8{\pm}15.8%$ and $72.6{\pm}19.8%$, respectively. The change in PIBW before and after tube feeding was significantly different among the BMI groups (P<0.01). The change in hemoglobin concentration before and after tube feeding was also significantly different among the BMI groups (P<0.01). When subjects were divided into three groups (<60%, 60~79%, ${\geq}80%$) according to the ratio of actually provided calories to required calories, there was no significant difference in nutrition screening indicators before and after tube feeding. When the subjects were divided into three groups (<60%, 60~79%, ${\geq}80%$) according to the ratio of actually provided protein to required protein, serum albumin concentration showed a significant difference among the groups before and after tube feeding (P<0.05). Therefore, an intensive nutrition intervention program would be needed for the nutritional improvement of ICU inpatients receiving tube feeding.

  • Anaplasma phagocytophilum의 주요 표면단백질인 Msp2 (p44)는 세균의 표면에 발현되는 주요한 항원 단백질이다. 본 실험에서는 A. phagocytophilum이 주요 숙주세포인 호중구나 HL-60 세포에 침입하는 데 있어, 세균의 주요 표면 단백질인 Msp2와 숙주세포의 표면에 발현되는 PSGL-1과의 반응 여부를 알아보았다. 그 결과, 재조합 단백질인 Msp2나 순수하게 분리된 A. phagocytophilum이 PSGL-1/FucT IV 유전자가 형질전환되어 PSGL-1이 발현되는 BJAB 세포와는 결합하지만, 순수한 BJAB 세포와는 전현 반응하지 않는 것을 관찰할 수 있었다(p<0.01 & p<0.01). 또한, 순수하게 분리된 A. phagocytophilum과 형질전환된(PSGL-1/FucT IV) BJAB 세포와의 결합이 Msp2의 단-클론항체나 Msp2 재조합 단백질의 농도에 따라 억제됨을 관찰할 수 있었다(p<0.05 & p<0.01). 따라서 A. phagocytophilum의 Msp2가 숙주세포인 호중구의 표면에 발현되는 PSGL-1과 직접적으로 결합하는 부착물질임을 알 수 있었다.

  • Objective: The purpose of present study was to investigate the effects of condensed molasses fermentation solubles (CMS) on lactation performance, rumen fermentation, nutrient digestibility, and serum parameters of dairy cows. Methods: A total of 75 healthy Holstein cows with the same parity (milk production = 35±2.5 kg, body weight = 570±28 kg) were randomly selected and divided into 5 groups. One group served as control group (CON; no CMS), whereas the other 4 groups were CMS1 (accounted for 1% of the diet), CMS2 (2%), CMS3 (3%), and CMS4 (4%). All cows were fed regularly three times each day at 0800, 1600, and 2400 h. Cows received diet and water ad libitum. The experiment lasted for 60 days. Results: Results showed that the dry matter intake, milk yield, and protein of CMS2 were maximum and higher (p<0.05) than CMS4. The ruminal pH was observed less than 6 in CMS3 and CMS4 groups. No noticeable difference of microbial protein was found between CON and CMS2 groups, while the microbial protein in these groups was higher (p<0.05) than CMS3 and CMS4 groups. The apparent digestibility of dry matter, organic matter, and crude protein in CMS2 group was higher (p<0.05) than CMS3 and CMS4 groups. Compared to CMS3 and CMS4 groups, the CMS2 group increased (p<0.05) the serum concentrations of immunoglobulin G and immunoglobulin M on d 60. Conclusion: Therefore, it is practicable that CMS substitutes for a part of concentrates in lactating cows' diets, but higher addition of CMS (more than 3% of the diet) could decrease production performance of dairy cows as seen in the present study.

  • In order to induce high levels of protein secretion, we have constructed a recombinant plasmid, designated pBP244, into which was incorporated key components of the type-II See-dependent secretion system, including LepB (signal peptidase), SecA (ATPase), and SecB (chaperone). The biological activities of the LepB, SecA, and SecB components expressed from genes harbored by pBP244 appeared to play their normal roles. In order to evaluate the protein secretion, a pspA (Streptococcus $\underline{p}neumoniae\;\underline{s}urface\;\underline{p}rotein\;\underline{A}$) gene was cloned into pBP244, resulting in pBP438. S. typhimurium harboring pBP438 grown until the stationary phase, secreted a higher level of PspA into the culture supernatants than did the strain harboring pYA3494. The strain harboring pBP438 secreted a supernatant amount 1.71-fold, a periplasmic space amount 1.47-fold, and an outer membrane amount 1.49-fold higher than that of pYA3494. S. typhimurium ${\chi}8554$ kept the $Asd^+$ plasmid pBP244 and pBP438 for 60 generations in LB broth harboring DAP, thereby indicating that pBP244 and pBP438 were quite stable in the Salmonella strain.

  • Growing pigs (N=25; 18 kg) were used to study effects of L-carnitine and protein intake on plasma carnitine, energy and carnitine balance, and carnitine biosynthesis. Corn-soybean meal basal diets containing low or high protein (13.6% or 18%) were formulated so that protein accretion would be limited by metabolizable energy (ME). Each basal diet was supplemented with 0 or 500 mg/kg L-carnitine and limit fed to pigs for 10 d in a balance trial. Final carnitine concentration was compared with weight/age matched pigs measured on d 0 to calculate carnitine retention rates. Supplementation of carnitine increased (p<0.01) plasma free carnitine (by 250%), short-chain (by 160%) and long-chain acyl-carnitine concentrations (by 80%) irrespective of blood sampling time (p<0.01). The proportion of long-chain carnitine esters decreased by 40% (p<0.01) by carnitine supplementation; whereas, the proportion of short-chain acyl-carnitine concentration was not changed (p>0.10). All criteria of energy balance were unaffected by L-carnitine (p>0.10). Total body carnitine retention was increased by 450% over unsupplemented controls (p<0.01). Carnitine biosynthesis rates in pigs fed diets without L-carnitine were estimated at 6.71 and $10.63{\mu}mol{\cdot}kg^{-1}{\cdot}d^{-1}$ in low protein and high protein groups, respectively. In supplemented pigs, L-carnitine absorption and degradation in the intestinal tract was estimated at 30-40% and 60-70% of L-carnitine intake, respectively. High protein feeding effect did not affected plasma carnitine concentrations, carnitine biosynthesis or carnitine retention (p>0.10). We conclude that endogenous carnitine biosynthesis may be adequate to maintain sufficient tissue levels during growth, but that supplemental dietary carnitine (at 500 ppm) sufficiently increased plasma acyl-carnitine and total body carnitine.

  • This study evaluated the in situ ruminal degradability, and subsequent small intestinal digestibility (SID) of dry matter, crude protein (CP), and amino acids (AA) of cottonseed meal (CSM), sunflower seed meal (SFSM) and distillers dried grains with solubles (DDGS) by using the modified three-step in vitro procedure. The ruminal degradability and subsequent SID of AA in rumen-undegradable protein (RUP-AA) varied among three protein supplements. The result show that the effective degradability of DM for SFSM, CSM, and DDGS was 60.8%, 56.4%, and 41.0% and their ruminal fermentable organic matter was 60.0%, 55.9%, and 39.9%, respectively. The ruminal degradable protein (RDP) content in CP for SFSM, CSM, and DDGS was 68.3%, 39.0%, and 32.9%, respectively, at the ruminal solid passage rate of 1.84%/h. The SFSM is a good source of RDP for rumen micro-organisms; however, the SID of RUP of SFSM was lower. The DDGS and CSM are good sources of RUP for lambs to digest in the small intestine to complement ruminal microbial AA of growing lambs. Individual RUP-AA from each protein source was selectively removed by the rumen microorganisms, especially for Trp, Arg, His, and Lys (p<0.01). The SID of individual RUP-AA was different within specific RUP origin (p<0.01). Limiting amino acid was Leu for RUP of CSM and Lys for both RUP of SFSM and DDGS, respectively. Therefore, different protein supplements with specific limitations should be selected and combined carefully in growing lambs ration to optimize AA balance.
