  • Eight ileally cannulated pigs (BW $35.9{\pm}0.9kg$) were randomly allotted according to a $4{\times}3$ Latin square design to determine the effects of cellulose, pectin and starch on standardized ileal digestibility (SID) and apparent total tract digestibility (ATTD) of crude protein (CP) and amino acids (AA) as well as on the bacterial AA contribution in feces. The pigs were fed the control diet (20.2% CP, % dry matter (DM)) or one of the three experimental diets in which 25% of the control diet was substituted by cellulose, starch or pectin. Due to this substitution, dietary CP levels were lower in the cellulose (15.5% CP, % DM), pectin (15.4% CP, % DM) and starch diet (15.2% CP, % DM). Following a 15-d adaptation period, feces were collected for 5 d and ileal digesta for a total of 24 h. Starch increased SID of CP, while cellulose and pectin had no significant effect on the digestibility of CP. Overall, starch supplementation resulted in higher (p<0.05) SID values of histidine, isoleucine, threonine, alanine, aspartic acid, cysteine, glycine and serine compared with cellulose, while pectin decreased (p<0.05) SID of valine and proline compared with the starch and control diet. Both cellulose and pectin reduced (p<0.05) the ATTD of CP and AA, while starch decreased (p<0.05) ATTD of phenylalanine, alanine, proline and serine compared with the control. With regard to bacterial AA composition of the fecal mixed bacterial mass (MBM), cellulose supplementation increased (p<0.05) its content of N and almost all AA, except for valine, while pectin caused higher contents of arginine, histidine and proline compared with the control (p<0.05). The bacterial contribution of arginine in feces was higher (p<0.05) in the cellulose treatment, while pectin reduced (p<0.05) the bacterial contribution of leucine, alanine, glutamic acid and proline in feces compared with the control. In conclusion, the effects of cellulose, starch and pectin on SID were rather small. Bacterial activity in the large intestine can only explain the reduced ATTD values for arginine in the cellulose treatment, but not for the other AA in the cellulose and pectin treatments, suggesting higher endogenous losses of these AA in the large intestine.

  • We examined the nutritive value of common grass species in the semi-arid rangelands of Borana in southern Ethiopia using local experience based herbage preference (LEBHP) perception and laboratory techniques. Local pastoralists in the study area were asked to identify common grass species and rank them according to the species' preferences and palatability to cattle. The pastoralists listed a total of 15 common grass species which were then sampled during the main rain and cold dry seasons and analyzed for crude protein (CP), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF) and ash content to verify pastoralists' claim regarding the quality of individual species. The relative feed value (RFV) and dry matter digestibility (DMD) were also calculated using NDF and ADF contents. Spearman's rank correlation was used to examine possible relationships between laboratory results and pastoralists' experience on grass quality. Cenchrus ciliaris, Chrysopogon aucheri, Digitaria milanjiana, Eragrostis papposa and Panicum maximum were the top five species based on LEBHP perception. There were indications of inconsistency in terms of LEBHP perception among the different pastoral communities. The chemical composition of all grass species showed significant (p<0.05) variation between sites, seasons and species. The results showed that the CP values for the Borana rangelands were in the range of 8.7% in the main rain season to 5.1% for the cold dry season. The fiber constituents were relatively low in the main rain season compared to the cold dry season. Overall, Digitaria milanjiana had the highest CP (16.5%) content, while the least was recorded with Heteropogon contortus (10.8) and Aristida adoensis (9.8%) during the main rain season. It seems that the spatial variability of landscapes within the wider geographical regions, soil properties and texture, and land-use patterns probably contributed to site differences in species quality. Generally, the RFV of individual grass species was significantly (p<0.05) varied between and within sites. The ranking of species by pastoralists according to their preferences by cattle was highly correlated with the chemical composition of laboratory results of individual grass species with 'r' values for CP (0.94), ash (0.95), NDF (-0.98), ADF (-0.93) and ADL (-0.93). We suggest the complimentary use of LEBHP and laboratory techniques in evaluating the nutritive quality of rangeland forage species for sustainable animal production.

  • Gastric cancer (GC) is one of the most common malignancies in the world. It is the first cause of cancer deaths in both sexes In Iranian population. Circulating insulin-like growth factor-one (IGF-1) levels have been associated for gastric cancer. IGF-1 protein has central roles involved in the regulation of epithelial cell growth, proliferation, transformation, apoptosis and metastasis. Single nucleotide polymorphism in IGF-1 regulatory elements may lead to alter in IGF-1expression level and GC susceptibility. The aim of this study was to investigate the influence of IGF-1 gene polymorphism (rs5742612) on risk of GC and clinicopathological features for the first time in Iranian population. In total, 241 subjects including 100 patients with GC and 141 healthy controls were recruited in our study. Genotypes were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay with DNA from peripheral blood. The polymorphism was statistically analyzed to investigate the relationship with the risk of GC and clinicopathological properties. Logistic regression analysis revealed that there was no significant association between rs5742612 and the risk of GC. In addition, no significant association between genotypes and clinicopathological features was observed (p value>0.05). The frequencies of the CC, CT, and TT genotypes were 97%, 3%, and 0%, respectively, among the cases, and 97.9%, 2.1%, and 0%, respectively, among the controls. CC genotype was more frequent in cases and controls. The frequencies of C and T alleles were 98.9% and 1.1% in controls and 98.5% and 1.5% in patient respectively. Our results provide the first evidence that this variant is rare in Iranian population and it may not be a powerful genetic predisposing biomarker for prediction GC clinicopathological features in an Iranian population.

  • Objective: The purpose of this study was to examine the role of programmed cell death 4 (PDCD4) expression in predicting tumor response to neoadjuvant chemoradiotherapy and outcomes for patients with locally advanced rectal cancer. Methods: Clinicopathological factors and expression of PDCD4 were evaluated in 92 patients with LARC treated with nCRT. After the completion of therapy, 4 cases achieved clinical complete response (cCR), and thus the remaining 88 patients underwent a standardized total mesorectal excision procedure. There were 38 patients (41.3%) with a good response (TRG 3-4) and 54 (58.7%) with a poor one (TRG 0-2). Results: Immunohistochemical staining analyses showed that patients with high expression of PDCD4 were more sensitive to nCRT than those with low PDCD4 expression (P=0.02). High PDCD4 expression before nCRT and good response (TRG3-4) were significantly associated with improved 5-year disease-free survival and 5-year overall survival (P<0.05). Multivariate analysis demonstrated that the pretreatment PDCD4 expression was an independent prognostic factor. Conclusion: Our study demonstrated that high expression of PDCD4 protein is a useful predictive factor for good tumor response to nCRT and good outcomes in patients with LARC.

  • The effect on sow milk of variable levels of cassava in lactating sow diets was analyzed in an attempt to explain the beneficial effects reported by producers of including cassava as a basal feed. Twenty crossbred lactating sows were randomly assigned to five dietary treatments. The treatments were: i) broken rice (BR) as the basal feed (BR100), ii) 50% of BR replaced with cassava chip meal (CCM) (CM50), iii) 75% of BR replaced with CCM (CM75), iv) CCM as the basal feed (CM100), and v) dried boiled cassava chips (CCB) as the basal feed (CB100). The hydrocyanide (HCN) content of CCB was reduced to be intermediate between HCN in the no cassava (BR100) and the 50% cassava (CB50) diets. Hydrocyanide was 0.54, 3.24, 4.41, 5.43 and 1.77 ppm in the BR100, CM50, CM75, CM100 and CB100 diets, respectively. Increasing cassava did not affect feed intake (p>0.05), but increased HCN intake (p<0.01). Milk composition was analyzed for protein, fat, lactose, solids not fat (SNF) and total solids (TS). Milk quality was analyzed for total microbes, coliform bacteria, thiocyanate ($SCN^-$), lactoperoxidase (LPO), and glutathione peroxidase (GPx) activity. At farrowing, sow milk composition was not affected by experimental diets (p>0.05), but milk $SCN^-$ increased as the intake of HCN increased in sows diets (p<0.01), $r^2$ = 0.96. At mid-lactation (day 14), milk composition was not affected (p>0.05). The milk quality levels of $SCN^-$ were 9.4, 10.3, 10.5, 11.6 and 9.1 ppm for the BR100, CM50, CM75, CM100 and CB100 diets, respectively (p = 0.01). The LPO contents were 16.41, 42.13, 51.42, 53.94 and 22.81 unit/L, respectively (p = 0.03). There was no GPx activity found in sow milk. When BR was replaced with cassava meal, total microbes and coliforms were reduced 78% and 87%, respectively, by the influences of HCN. The reported beneficial effects of cassava chip meal as a basal feed in lactating sow diets is manifested by improved performance of suckling pigs. This is due to beneficial, non-toxic levels of HCN in the diets. Besides passing HCN to suckling pigs in the form of $SCN^-$, sow milk may also benefit suckling pigs with the observed (day 14) increase in lactoperoxidase content and reduction in coliform bacteria.

  • This study was designed to comparse the metabolic effects of Korean diet pattern which contained all-polished rice and 70% polished rice, and to compare dietary restriction. The results were as follows. 1. Food intake survey to catch the Korean diet pattern The calory intake showed women took much more than men and farm village was higher than city, However, protein intake showed men were higher than women and decrease gradually from city, fishing village, and farm village. Calcium intake showed Seoul was the first rank of all, but was merely 70% of recommended quantities. Fe intake was greatly short especially in women and vitamin C also showed same situation. In the view of food group intake, grains and potatoes were 70.06%, vegetables and fruits 13.05%, meats fishes and beans 11.99%, respectivelly. Oil and fat intake showed lowest percentage as 0.77%. 2. Nutritional experiments albino rats have been fed for 7 weeks with three different diet: all-polished rice diet, 70% polished rice diet, and the standard diet for contral group. Dietary restriction were at 4 levels: 5% , 10%, 15%, 20% in 70% polished rice det. Body weight of 70% polished rice group gained value compare to all polished rice group. In the final organ weight all-polished rice group and 70% polished rice group and 70% polished rice group revealed similar results, but organ weight almost decreased dued to dietary restriction and statistical data showed significant differences between dietary restriction group and none-restriction group. In the femur length, 70% polished rice group was longer than all polished rice group but there was no significant differences. The nitrogen content of liver and muscle of 70% polished rice group was higher than all-polished rice group. Furthermone there was significant differences in the female (P<0.1). In the 10% restriction group(female) and 15% restriction group(male), nitrogen retention was higher than 0% restriction group. The other biochemical analysis such as liver lipid, serum cholesterol, glucose of urine, feces and serum were not revealed any significant differences. As a result of studying, it seems clear that 70% polished rice intake influenced much nourshment to white rat growth than all-porished rice intake, and there is no significant influence to animal growth and metabolic effect even if it was restricted $5{\sim}10%$ of diet.

  • Objective : Infectious spinal disease is regarded as an infection by a specific organism that affects the vertebral body, intervertebral disc and adjacent perivertebral soft tissue. Its incidence seems to be increasing as a result of larger proportion of the older patients with chronic debilitating disease, the rise of intravenous drug abuser, and the increase in spinal procedure and surgery. In Korea, studies assessing infectious spinal disease are rare and have not been addressed in recent times. The objectives of this study are to describe the epidemiology of all kind of spinal infectious disease and their clinical and microbiological characteristics as well as to assess the diagnostic methodology and the parameters related to the outcomes. Methods : A retrospective study was performed in all infectious spinal disease cases presenting from January 2005 to April 2010 to three tertiary teaching hospitals within a city of 1.5 million in Korea. Patient demographics, risk factors, clinical features, and outcomes were assessed. Risk factors entailed the presence of diabetes, chronic renal failure, liver cirrhosis, immunosuppressants, remote infection, underlying malignancy and previous spinal surgery or procedure. We comparatively analyzed the results between the groups of pyogenic and tuberculous spinal infection. SPSS version 14 statistical software was used to perform the analyses of the data. The threshold for statistical significance was established at p<0.05. Results : Ninety-two cases fulfilled the inclusion criteria and were reviewed. Overall, patients of tuberculous spinal infection (TSI) and pyogenic spinal infection (PSI) entailed 20 (21.7%) and 72 (78.3%) cases, respectively. A previous spinal surgery or procedure was the most commonly noted risk factor (39.1%), followed by diabetes (15.2%). The occurrence of both pyogenic and tuberculous spondylitis was predominant in the lumbar spine. Discs are more easily invaded in PSI. At initial presentation, white cell blood count and C-reactive protein levels were higher in PSI compared to TSI (p<0.05). Etiological agents were identified in 53.3%, and the most effective method for identification of etiological agents was tissue culture (50.0%). Staphyococcus aureus was the most commonly isolated infective agent associated with pyogenic spondylitis, followed by E. coli. Surgical treatment was performed in 31.5% of pyogenic spondylitis and in 35.0% of tuberculous spondylitis cases. Conclusion : Many previous studies in Korea usually reported that tuberculous spondylitis is the predominant infection. However, in our study, the number of pyogenic infection was 3 times greater than that of tuberculous spinal disease. Etiological agents were identified in a half of all infectious spinal disease. For better outcomes, we should try to identify the causative microorganism before antibiotic therapy and make every effort to improve the result of culture and biopsy.

  • The effect of chlorella addition on the quality characteristics of processed cheese was investigated. Chlorella processed cheese was prepared in the different ratio of chlorella (0.5% (w/w) and 1.0% (w/w)). Chlorella processed cheese was stored at $10{\pm}1^{\circ}C$ and evaluated for the quality characteristics including general composition, pH, the number of microorganisms, oiling off, meltability, rheological properties, color, and sensory evaluation. Contents of moisture, protein, fat, fat in dry matter, and pH values were not different from those of control cheese. Microorganisms were not detected. The degree of oiling off showed no significant difference, but meltability decreased significantly (p<0.05). Hardness and springiness gradually increased significantly (p<0.05), while cohesiveness gradually decreased significantly (p<0.05). The L (lightness) values and the a (redness) values decreased with increasing chlorella contents, but the b (yellowness) values increased with increasing chlorella contents, so color expressed yellowish green. Compared to control cheese made by conventional way, QDA scores of color and mouthfeel of chlorella processed cheese were significantly higher (p<0.05) and the most favorite quality characteristics were shown in the processed cheese with 0.5% (w/w) chlorella (CPC1). These results suggested that health-oriented chlorella processed cheese would be made by the addition of the chlorella.

  • Purpose : It is difficult to diagnose acute pyelonephritis(APN) in young children, because of their nonspecific symptoms. The younger the age, the higher the risk of renal scars after APN, which can be prevented by early diagnosis and treatment. We compare the significance of renal imaging studies by age for diagnosis of APN in febrile urinary tract infection(UTI) in children. Methods : Fifty-three hospitalized children(34 patients under age 2 and 19 patients over age 2) with febrile UTI and who had undergone dimercaptosuccinic acid(DMSA) scan, renal ultra sonography(RUS) and voiding cystourethrography(VCUG) during the acute stage were re-viewed. We compared the renal imaging studies between the different age groups. Results : The DMSA scan showed cortical defects in 23.5% of patients under age 2, which was significantly lower than 63.2% of patents over age 2(P<0.05). The renal cortical defects on DMSA scan were associated only with a high peripheral leukocyte count, but not with fever duration, erythrocyte sedimentation rate(ESR), and C-reactive protein(CRP). And there was no correlation between the DMSA scan, VCUG or RUS findings. Conclusions : The DMSA scan is not sensitive for diagnosis of APN in children less than 2 years of age and the findings cannot predict the presence of vesicoureteral reflux(VUR). VCUG may be necessary for proper management in this age group.

  • Free sugars were isolated from ginseng root and its products and analyzed by using high performance liquid chromatogrphy. To isolate free sugars from aqueous sample solution fat-soluble components, crude saponin and protein were removed from the solution by extracting with benzene, water-saturated butanol and 80% ethanol, respectively. Free sugars found from both ginseng root and its products were fructose, glucose, sucrose and maltose, and the only sugar detected from red ginseng root and its products was rhamnose. Major sugar detected from fresh ginseng and white ginseng roots was sucrose, while sucrose and maltose were major sugars of red ginseng root.
