The present experiment was conducted to study the effects of partial replacement of spray-dried porcine protein (SDPP) or fish meal with soybean and shrimp protein hydrolysate (SSPH) on growth performance, nutrient digestibility and serum biochemical parameters in weaned pigs. Two hundred and forty 21${\pm}$2 d old pigs ((Pietrain${\times}$Duroc)${\times}$(Landrace${\times}$Large Yorkshire)) with initial weight of 6.9${\pm}$0.5 kg were randomly allocated to five dietary treatments with six replicates per treatment and eight piglets per replicate. The control diet (T1) contained 2% SDPP and 6% fishmeal, and SDPP for experimental diets T2 and T3 was replaced with 1% and 2% SSPH, respectively, on an iso-nitrogenous basis. The fishmeal for experimental diets T4 and T5 was replaced with 1% and 2% SSPH, respectively, also on an iso-nitrogenous basis. The experimental period was 21 days. The results showed that weaned piglets fed the diets containing 1% and 2% SSPH as a replacement for SDPP had similar average daily gain (ADG), average daily feed intake (ADFI), feed/gain (F/G), diarrhea rate and serum biochemical indices e.g. blood urea nitrogen (BUN), total serum protein (TP), albumin to globulin ratio (A/G), globulin (GLO), serum glucose (GLU), and immunoglobulin G (IgG) to those fed the control diet during 0-10 d and 0-21 d of the experiment. The substitution of 1% SSPH on an iso-nitrogenous basis for fish meal appeared to be beneficial for ADG (p = 0.59) and ADFI (p = 0.23) of piglets during the overall period. The digestibility of calcium was higher (p<0.01) in pigs fed diets containing SSPH than on the control diet. Addition of 1% SSPH on an iso-nitrogenous basis for fish meal could increase the digestibilities of dry matter and energy of the diet. Dietary replacement of fish meal with 1% and 2% SSPH had no effect on the concentrations of BUN, TP, A/G, GLO, GLU, and IgG. In conclusion, dietary SDPP or fish meal could partially replace SSPH without any adverse effect on growth performance, nutrient digestibility and serum biochemical parameters in weaned piglets.

Purpose: Anorexia is a common symptom in terminal cancer patients. Some data have suggested a role of visfatin in regulating feeding behavior. We studied the relationship of a serum visfatin level and anorexia in cancer patients provided with hospice care. Methods: After informed consent was obtained, 69 cancer patients over 20 years old at a hospice center were enrolled in the study from July 2009 to July 2010. We characterized patients by age, sex, body mass index, primary cancer site, and Eastern Cooperative Oncology Group (ECOG) performance status, etc. Also, blood tests were performed to measure the level of hemoglobin, white blood cell (WBC), C-reactive protein (CRP), total cholesterol, albumin, lymphocyte count, glucose, blood urea nitrogen (BUN), creatinine, tumor necrosis factor-alpha (TNF-${\alpha}$), interukin-6, leptin and visfatin. Results: The mean age of subjects was 65.5 years old, According to univariate analysis, pulse, ECOG performance scale, opioid use and visfatin level were different between the anorexia and non-anorexic group (P<0.05). The median visfatin level was higher in the anorexia group than the good appetite group (P=0.0323). Serum visfatin concentrations were not related with either body mass index or serum leptin or total cholesterol levels, but it was negatively correlated with serum albumin levels (P=0.0198) and lymphocyte counts (P=0.0013). Conclusion: This study did not identify a novel link between visfatin levels and anorexia in cancer patients at a hospice.

Objective: Bioactive compounds in ruminant products are related to functional compounds in their diets. Therefore, this study aimed to explore the effect of forage sources, Italian ryegrass (IR) silage vs corn silage (CS) in the total mixed ration (TMR), on milk production, milk composition, and phytanic acid content in milk, as well as on the extent of conversion of dietary phytol to milk phytanic acid. Methods: Phytanic acid content in milk was investigated for cows fed a TMR containing either IR silage or CS using 17 cows over three periods of 21 days each. In periods 1 and 3, cows were fed CS-based TMR (30% CS), while in period 2, cows were fed IR silage-based TMR (20% IR silage and10% CS). Results: The results showed that there were no differences in fat, protein, lactose, solids-not-fat, somatic cell count, and fatty acid composition of milk among the three experimental periods. There were no differences in the plasma concentration of glucose, triglycerides, total cholesterol, and nonesterified fatty acids among the three experimental periods, while the blood urea nitrogen was higher (p<0.05) in period 2. The milk phytanic acid content was higher (p<0.05) in period 2 (13.9 mg/kg) compared with periods 1 (9.30 mg/kg) and 3 (8.80 mg/kg). Also, the phytanic acid content in the feces was higher (p<0.05) in period 2 (1.65 mg/kg dry matter [DM]) compared with period 1 (1.15 mg/kg DM), and 3 (1.17 mg/kg DM). Although the phytol contents in feces did not differ among the three feeding periods, the conversion ratio from dietary phytol to milk phytanic acid was estimated to be only 2.6%. Conclusion: Phytanic acid content in cow's milk increases with increasing phytol content in diets. However, phytol might not be completely metabolized in the rumen and phytanic acid, in turn, might not be completely recovered into cow's milk. The change of phytanic acid content in milk may be positively correlated with the change of phytol in the diet within a short time.

Objective: This study was conducted to investigate the hypoglycemic effect and safety of Ojeok-san in patients with type 2 Diabetes Mellitus. Methods: We investigated type 2 diabetes mellitus patients at Kyung-Hee University Korean Medical Hospital who were administered Ojeok-san for at least one day between January 2012 and September 2020, basal characteristics and laboratory tests were reviewed retrospectively. The hypoglycemic effect of Ojeok-san was assessed by comparing fasting blood sugar (FBS) and two hours post-prandial plasma glucose (PP2) levels from before and after taking Ojeok-san. Subgroup analyses were conducted according to baseline hypoglycemic treatments and glycated hemoglobin levels (< or ≥6.5%). The safety of Ojeok-san was assessed by comparing levels of aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transferase, blood urea nitrogen, and creatinine. Results: After Ojeok-san administration, FBS and PP2 were significantly reduced to an average of 14.33 mg/dL and 27.67 mg/dL respectively. In the subgroup analysis, PP2 in patients receiving metformin mono therapy was significantly reduced to 28.67 mg/dL, and those receiving a dual therapy of metformin and DPP-4 inhibitor, it was significantly reduced to 32.33 mg/dL. In patients with glycated hemoglobin of lower than 6.5%, FBS was significantly reduced to 12.20 mg/dL, and both FBS and PP2 were significantly reduced, to 15.50 mg/dL and 40.00 mg/dL, respectively, in those with glycated hemoglobin levels of more than 6.5%. The safety profile showed no significant difference after Ojeok-san administration. Conclusions: Ojeok-san has significant hypoglycemic effects in patients with type 2 diabetes mellitus who are also taking hypoglycemic agents.

Renal ischemia-reperfusion injury(IRI), an important cause of acute renal failure (ARF), cause increased renal tubular injury. Jesaeng-sinkihwan (JSH) was recorded in a traditional Chines medical book named "Bangyakhappyeon (方藥合編)". JSH has been used for treatment of diabetes and glomerulonephritis with patients. Here we investigate the effects of Jesaeng-sinkihwan (JSH) in a mouse model of ischemic acute kidney injury. The animals model were divided into four groups at the age of 8 weeks; sham group: C57BL6 male mice (n=9), I/R group: C57BL6 male mice with I/R surgery (n=9), JSH Low group: C57BL6 male mice with surgery + JSH 100 mg/kg/day (n=9) and JSH High group: C57BL6 male mice with surgery + JSH 300 mg/kg/day (n=9). Ischemia was induced by clamping the both renal arteries during 25 min, and reperfusion was followed. Mouse were orally given with JSH (100 and 300 mg/kg/day during 3 days after surgery. Treatment with JSH significantly ameliorates creatinine clearance(Ccr), Creatinine (Cr) and blood urea nitrogen(BUN) in obtained plasma. . Treatment with JSH reduced kidney inflammation markers such as Neutrophil Gelatinase Associated Lipocalin (NGAL) and kidney injury molecule-1 (KIM-1). JSH also reduced the periodic acid schiff (PAS) staining intensity and picro sirius red staining intensity in kidney of I/R group. These findings suggest that JSH ameliorates tubular injury including renal dysfunction in I/R induced ARF mouse.

Objectives: The purpose of this study was to examine the biochemical characteristics, intake of energy, and nutrients by household income levels of Korean adolescents aged 12 to 18 years. Methods: Data from the 6th (2013 ~ 2015) Korea National Health and Nutrition Examination Survey (KNHNES) were used for the study. A total of 1,839 (966 boys, 873 girls) subjects were included, and they were divided into four income groups according to their household income level. We examined general characteristics (gender, region of residence, skipping or not-skipping breakfast, lunch, dinner, frequency of eating-out), anthropometric characteristics (height, weight, weight status), biochemical characteristics (fasting plasma glucose, blood urea nitrogen, creatinine, triglycerides, cholesterol, HDL-cholesterol, hemoglobin, and hematocrit), the quantitative intake of energy and nutrients using the Korean Dietary Reference Intakes (KDRI), and the qualitative intake evaluated by the nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) of the four groups. Results: There were significant differences by income group within the region of residence and the rate of skipping breakfast, lunch, and dinner. The low-income group had a higher rate of skipping breakfast, lunch, and dinner. According to the income group, there was a difference in the height of boys, and there was no difference in the weight and obesity of boys and girls. In the biochemical characteristics, only the hematocrit of girls showed differences by income group. The quantitative intake of energy and nutrients compared with KDRI differed by income group. There were differences in energy, carbohydrates, proteins, thiamin, riboflavin, niacin, and phosphorus levels in boys and protein, vitamin A, niacin, and sodium levels in girls. The qualitative intake of energy and nutrients examined using NAR and MAR also differed according to the income group. The NAR showed differences in calcium in boys and vitamin C and calcium in girls. The MAR revealed differences in both boys and girls by income group. Conclusions: Among adolescents in the low-income group, the rate of skipping meals was high, and the quantitative and qualitative intake of energy and some nutrients was low. It is suggested that the nutritional intake can be improved by lowering the rate of skipping breakfast, lunch, dinner. We suggest that even just providing breakfast in schools can be considered highly effective in improving the rate of avoidance of skipping meals and improving nutrient intake. Also, we suggest that it is necessary to improve the food environment, food availability, and food accessibility through national and social support for low-household income adolescents.

Objectives: The purpose of this study was to compare the sex-associated differences in the dietary intake of gastric cancer patients in Korea. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHANES) the 7^th (2016-2018) were analyzed in the present study. The subjects included 122 gastric cancer patients aged over 40 years (75 male, 47 female). General characteristics (age, marital status, household income, education, food security, comorbidities, alcohol drinking, and smoking), anthropometric characteristics (height, weight, body mass index, and blood pressure), blood biochemical characteristics [fasting plasma glucose (FPG), blood urea nitrogen (BUN), creatinine, triglyceride, total cholesterol, and HDL-cholesterol)], and quantity and quality of dietary intake were compared between male and female participants. Results: Males had higher rates of having a spouse, prevalence of hypertension, alcohol drinking, and smoking than females. The proportion of males with a normal range of FPG, BUN, and HDL-cholesterol was lower than that in females. The total cholesterol levels above the normal range were higher in females than in males. We also found that females had a higher percentage of intakes below the estimated energy requirement (EER) and intakes below the estimated average requirement (EAR) for carbohydrates, niacin, phosphorus, and iron than males. The index of nutritional quality (INQ) for phosphorus and folate, nutrient adequacy ratio (NAR) for vitamin C, thiamine, niacin, folate, calcium, and phosphorus, and the mean adequacy ratio (MAR) were lower in females than males. Conclusions: In Korean gastric cancer patients, management of comorbidities such as diabetes and hypertriglyceridemia, lowering FPG, and raising HDL-cholesterol level management is required for males, whereas management of lowering total cholesterol and raising hematocrit is required for females. The quantitative and qualitative nutritional intakes were poor in gastric cancer patients, especially in females, who had a lower nutritional intake than males. We suggest that nutritional interventions are needed to improve the overall nutritional intake in both male and female gastric cancer patients. In particular, we propose that support is urgently needed for females whose nutritional intake is lower than that of males. In addition, family, social, and national support for nutritional management of female gastric cancer patients is highly necessary.

This study was performed to investigate the effects of the stocking density (standard stocking density (SSD, $495cm^2/bird$)) vs. high stocking density (HSD,245cm2/bird) and challenge with lipopolysaccharide (LPS, 5mg/kg BW) on the stress-related physiological indicators in chicks. There was a significant (p<0.05) decrease in body weight, but not in the weight of immune organs, between the SSD and HSD groups. The LPS group resulted in a significant (p<0.05) increase in the weights of the thymus and bursa of fabricius compared with the SSD group. Plasma biochemical components, including aspartate transaminase (AST), alanine transaminase (ALT), blood urea nitrogen, Ca, P, creatine kinase and uric acid, markedly (p<0.05) increased in the LPS birds, although no difference in these parameters was observed between the SSD and HSD birds. Furthermore, the birds challenged with LPS showed a significant (p<0.05) increase in the plasma corticosterone level, although this hormone did not differ between the SSD and HSD groups. In the mRNA expression of pro-inflammatory cytokines, hepatic $IL-1{\beta}$, IL-6 and iNOS in the LPS group significantly (p<0.05) increased compared with those in the SSD group. Thymic mRNA expression of $IL-1{\beta}$, IL-6 and IL-18 in the LPS group also significantly (p<0.05) increased compared with those in the other groups. In addition, mRNA expression of $IL-1{\beta}$ in the bursa of fabricius of the LPS group increased (p<0.05) without affecting the other cytokines. Under high stocking density, thymic $IL-1{\beta}$ was the only cytokine that was up-regulated compared with the SSD group. In conclusion, an acute stress induced by LPS challenge profoundly affected immune organ weight, blood biochemical profiles and pro-inflammatory cytokine expression, while chronic stress did not markedly affect biochemical and immunological parameters, suggesting that chicks under high stocking density could be adapted to prolonged stressors.

This study investigated the effects of green tea polyphenol and vitamin C on type 2 diabetes mellitus by administering polyphenon 60 (P60) and sodium ascorbate (SA) to diabetic rats induced by high fat diet/low-dose streptozotocin. The experimental group was divided into five different groups: non-diabetic control group (NC), diabetes control group (DC), diabetes+P60 group (DM+P60), diabetes+SA group (DM+SA), and diabetes+P60+SA group (DM+P60+SA). P60 and SA were dissolved in 0.1% drinking water. After P60 and SA were administered for 16 weeks, fasting blood glucose, plasma insulin, serum triglyceride, blood urea nitrogen (BUN), and creatinine levels as well as kidney alkaline phosphatase (AP) and ${\gamma}$-glutamyltranspeptidase (GGT) activities were measured. Fasting blood glucose level increased 5-fold in the DC group compared to the NC group. In the DM+P60 group, fasting blood glucose level decreased by 14%. In the DM+P60+SA group, fasting blood glucose level decreased by 28% compared to the DC group, whereas the DM+SA group did not show any significant difference. The homeostasis model assessment for insulin resistance index increased in the DC group and decreased in the DM+P60+SA group compared to the DC group. Serum creatinine level increased in the DC group, but decreased by 17% in the DM+P60 group and by 43% in the DM+P60+SA group compared to the DC group. The serum BUN level increased in the DC group, but decreased by 41% in the DM+P60+SA group compared to the DC group. Kidney GGT and AP activities decreased in the DC group compared to the NC group; however, they were reversed by DM+P60+SA group. These results show that combined administration of both green tea polyphenol and vitamin C had better effects on improving blood glucose level, insulin resistance, serum triglyceride level, and protecting kidneys than administration of either green tea polyphenol or vitamin C alone in the context of type 2 diabetes.

In this study, we aimed to investigate the effects of dietary supplementation with fruiting body of Agaricus brasiliensis (AB) mushroom on the lipid profiles of serum and histological patterns of liver of high cholesterol-fed rats. Five-week-old, female Sprague-Dawley albino rats were divided into three groups of 8 rats each, including a normal control-diet (NC) group, a high-cholesterol diet (HC) group, and a group fed high-cholesterol diet supplemented with 5 % powder of Agaricus brasiliensis fruiting bodies (HC+AB). Total serum cholesterol, low density lipoprotein (LDL), and triglyceride (TG) concentrations in the HC+AB group were significantly reduced when compared with those in the HC group. Body weight in the HC+AB group was significantly lower than that in the HC group, whereas no adverse effects were observed on the levels of plasma albumin, creatinine, blood urea nitrogen, uric acid, glucose, and total protein. In the HC+AB group, liver enzyme activities related to liver function, such as GOT and GPT, presented values lower than those in the HC group and were very similar to the ones in the NC group. Excretion of total lipid and cholesterol in feces in the HC+AB group was significantly higher than that in the NC and HC groups, indicating that mushroom feeding inhibits the absorption of lipid cholesterol in the intestine. Liver histopathological analyses revealed that rats fed with HC diet developed fat liver disease, whereas only small amounts of fat were deposited in the livers of the HC+AB group. In conclusion, the results suggest that fruiting body powder of A. brasiliensis provides health benefits to high-cholesterol-fed rats by lowering body weight and the risk of atherogenic lipid profile.
