This experiment aims to observe the nutritive value of blood sausages by manufacturing three kinds of them in order to utilize various by-products of swine when it is processed. In attempt to do so, five different diets were made: one control diet and four diets in which three kinds of blood sausages(blood sausage-1 was made with sausage meat 10%, fat 40%, blood 20%, skin 20% and liver 2%. blood sausage-2 was made with ham meat 30%, fat 20%, blood 20%, liver 2% and skin 20%. blood sausage-3 was made with smoked ham patch 30%, fat 20%, blood 20%, liver 2% and skin 20%) and mixed sausage(sausage meat 20%, fat 10% and fish meat 35%) were mixed with control diet at the rates of 10% respectively. These diets were fed to growing male and female albino rats for 6 weeks. The results obtained through this study are summarized as follows. In body weight gain of male rats, blood sausage-1 and 2 groups were significantly higher than mixed sausage group during the experimental period, and in that of female rats, control group and blood sausage-1 group were similar, but the other groups were lower than control group. Food intake was different in each group every week, but the amount of that was similar to each one throughout all experimental period. Food efficiency ratio and protein efficiency ratio in male were similar in each group, but slightly different in female during the feeding period. Liver weights of male in mixed sausage group and blood sausage-3 group were lower than those in control group and blood sausage-2 group, but liver weight of female in blood sausage-2 group was lower than that in control group. And all groups were similar in liver weight per 100 g of body weight. Mixed sausage group and blood sausage-1 group were lower than control group in kidney weight of male, and blood sausage-1 group was lower than control group in kidney weight of female. Kidney weight per 100 g of body weight of male showed that blood sausage-1 group was lower than the other groups. Spleen weight was similar in all groups. Hematocrit and hemoglobin contents in blood, total protein, albumin, albumin/globulin ratio, total lipid and total cholesterol contents in serum were showed almost similar in all groups.

Purpose : Early identification of iron deficiency in young children is essential to prevent damaging long-term consequences. It is often difficult for the pediatrician to know which indices should be used when diagnosing these conditions especially in hospitalized young children. This study investigated the clinical significances of reticulocyte hemoglobin content in young children with acute infection. Methods : We studied 69 young children aged from 6 to 24 months admitted with acute infection in a single center. Venous blood was drawn to determine hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), hemoglobin content (CH), reticulocyte hemoglobin content (CHr), and red blood cell distribution width (RDW) using ADVIA 120 (Bayer Diagnostics, NY, USA). For evaluating iron status, iron, total iron binding capacity, ferritin and transferrin saturation (Tfsat) were determined. Iron deficiency was defined as Tfsat less than 20%, and iron deficiency anemia as Tfsat less than 20% and Hb level less than 11 g/dL. Results : In all, 47 were iron deficient; 17 of these had iron deficiency anemia. CHr was the only significant predictor of iron deficiency (likelihood ratio test=71.25; odds ratio=0.67; P<0.05). Plasma ferritin level had no predictive value (P=0.519). Subjects with CHr less than 27.4 pg had lower Hb level, MCH, CH, Tfsat, and iron levels than those with CHr 27.4 pg or more (P<0.05 for all). Conclusion : CHr level was a sensitive screening tool and the strongest predictor of iron deficiency in hospitalized infants with acute infection; it was cost saving and avoiding additional sampling. However its reference range should be established.

For centuries, ginseng has been used for the therapeutic purpose in oriental herb medicine. Several studies have been conducted in the past to evaluate the effect of ginseng on erythropoiesis. However the results were controversial. We therefore attempted in the present studies to evaluate the effect of ginseng on the erythropoietic activity. In one series of experiments, the recovery pattern of peripheral blood(red cell count, hemoglobin content, hematocrit and reticulocyte count) was studied in posthemorrhagic anemic rabbits. After animals were maintained with normal(control group) or 1 gm% ginseng (experimental group) diet for 2 weeks, hemorrhagic anemia was induced by withdrawing blood equivalent to 25% of the total blood volume and then changes in peripheral blood were followed for following 30 days. In other series of experiments, we studied effect of ginseng on erythrokinetics using $^{59}Fe$. $^{59}Fe(10{\sim}40\;{\mu}Ci/animal)$ was injected intravenously after animals were fed with normal (control group) or 1 gm% ginseng(experimental group) diet for 2 weeks. And radioactivities in the blood compartments were measured at appropriate intervals for 15 days. Front these various erythrokinetic parameters were estimated. Results are summarized as follows: 1) Reticulocyte count was higher in the experimental group than in the control group after 2 weeks of administration of experimental diet. During the posthemorrhagic period, the reticulocyte count increased in both the control and experimental groups, but the increase appeared much earlier in the experimental group. 2) The posthemorrhagic recoveries of hematocrit, hemoglobin content and red cell count appeared to be faster in the experimental group as compaired with the control group. 3) The half life$(T_{1/2})$ of $^{59}Fe$ in the plasma was significantly(P<0.05) shorter in the experimental group(82.6 min, N=8) than in the control group(121 min, N=6). Plasma iron turnover (PIT) of the experimental group (1.78 mg/dl/24 hr.) was approximately 4 times greater than that of the control group(0.45 mg/dl/24 hr.). 4) The maximum red cell utilization(RC-U) was 82.1% in the experimental group ana 74.5% in the control group. Red cell iron turnover(RIT) of the experimental group(1.62 mg/dl/24 hr.) was slightly higher than that of the control group(0.35 mg/dl/24 hr). 5) Erythron turnover was significantly(p<0.05) greater in the experimental group(1.27 mg/dl/24 hr.) than in the control group(0.24 mg/dl/24 hr.). Marrow transit time of the experimental group(2.05 days) tended to he faster than that of the control group(2.84 days). These results suggest that the gingseng improves the recovery of posthemorrhagic anemia and stimulates the erythropoiesis in rabbits.

Carnosine is a dipeptide $(\beta-alanyl-L-histidine)$ found in mammalian brain, eye, olfactory bulb and skeletal muscle at high concentrations. Its biological functions include antioxidant and anti-glycation activities. The objectives of this study were to investigate anti-diabetic effects of carnosine as determined by blood glucose levels, glucose tolerance test (GTT), glycosylated hemoglobin, and serum biochemical and lipid levels in streptozotocin-induced diabetic mice. There were five experimental groups including normal (ICR mice), control (saline), and three groups of carnosine at doses of 6, 30, and 150 mg/kg b.w.. Carnosine was orally administered to the diabetic mice everyday for 12 weeks. There was no significant difference in body weight changes in carnosine-treated groups compared to the control. The treatments of carnosine at the dose of 6 mg/kg significantly decreased the blood glucose level compared with the control at 2 and 4 weeks. The treatments of carnosine at the doses of 6 and 30 mg/kg significantly decreased the blood glucose levels in GTT and glycosylated hemoglobin compared with the control. Carnosine significantly increased total proteins compared with the control. Carnosine at the dose of 6 mg/kg significantly decreased total cholesterol and triglyceride in the serum compared to the control. These results suggest that carnosine at a low level has a hypoglycermic effect resulting from reduction of blood glucose and that a carnosine-containing diet or drug may give a benefit for controlling diabetes mellitus in humans.

Effect of vitamin C (VC) on biochemical, hematological and cortisol profile of growing Holstein calves during summer was investigated. Eighteen calves between 14 and 16 weeks of age were divided equally into two groups. One group received a diet supplemented with VC (20 g/d) for 60 days, while other non-supplemented diet fed group served as a control (CON). The temperature humidity index (THI) was recorded and computed during the experiment. From days 0 to 60, the THI exceeded 70. Blood samples were collected from the jugular vein of each calf at days 0, 15, 30, 45 and 60. Serum albumin and total protein decreased (p<0.05) in CON and VC calves with age. Serum glutamic-oxaloacetic transaminase concentrations were not affected by treatments. Serum creatinine, albumin and glutamic-pyruvic transaminase concentrations were higher in calves in the VC group than the CON group. While red blood cells, hemoglobin and hematocrit were lower (p<0.05) in VC calves, mean corpuscular volume, mean corpuscular hemoglobin, red blood cell distribution width and mean platelet volume were higher (p<0.05) in these VC supplemented calves. Leukocyte parameters including white blood cells and full term for lymphocytes were not affected by the treatments. Also, serum cortisol was not affected by treatments. At day 15, 30 and 45, the total VC in plasma was higher (p<0.05) in calves fed with VC. In conclusion, serum cortisols were not affected by plasma VC concentration, while some blood parameters were positively influenced in calves fed with VC.

Objectives: This study examined the effects of nutrition education and exercise therapies on the hematological status and diabetes knowledge of diabetic patients. For this purpose, a 12-week intensive management program was provided to diabetic patients participating in an exercise program in S health subcenter in Kwangju city and the effects were analyzed. Methods: The subjects were 26 diabetic patients, who provided written informed consent. As a preliminary survey, this study examined the general characteristics, physical status, obesity, blood pressure, hematological status, daily activity level, diabetes knowledge, diet performance, and barriers to diet therapy. After the 12-week intensive management program was completed, a post-test was conducted in the same way as the preliminary test. The data were analyzed with using SPSS 18.0. The data from this study are presented as the mean${\pm}$standard deviation. A paired t-test was conducted to compare differences in the means before and after the program. Statistical significance was set to p<0.05. Results: The results of the program are presented as follows. The HDL-cholesterol levels changed from $39.8{\pm}10.5mg/dL$ to $48.3{\pm}13.1mg/dL$, showing a significant increase (p<0.001). The blood sugar 2 hours after a meal changed from $175.2{\pm}67.1mg/dL$ to $140.5{\pm}42.5mg/dL$, showing a significant decrease (p=0.014). The glycosylated hemoglobin levels decreased significantly from $6.7{\pm}1.1%$ to $6.3{\pm}1.0%$ (p=0.010). The total scores of the daily activity levels increased significantly from $3.8{\pm}2.4$ to $4.8{\pm}2.5$ (p=0.040). The scores of knowledge on diabetes increased from $11.5{\pm}3.6$ to $14.0{\pm}3.8$ (p=0.001). The scores of knowledge on diet therapy changed from $6.7{\pm}2.2$ to $7.9{\pm}1.7$, showing a significant increase (p=0.027). Conclusions: The 12-week intensive management program intervened by nutrition education and exercise therapies induced positive changes to the HDL-cholesterol, blood sugar 2 hours after a meal, glycosylated hemoglobin, daily activity levels, and knowledge on diabetes.

Background: This study aimed to analyze the on heart rate, blood lactate concentration, packed cell volume (PCV) and hemoglobin (Hb) response after conducting exercise in endurance horses. Methods: A total of 20 healthy 3-9-years-old Jeju crossbreed mares ($5.95{\pm}2.24$ year) of age and $312.65{\pm}13.59kg$ of weight) currently participating the endurance competition were used. The field tests selected for the experiment was gallop (approximately 8.3 m/s) along the selected 2.5 km course (a natural forest trail, not artificial road; a closed loop course). The horses were divided into three groups according to their age; 3-4 years of age (G1, $3.29{\pm}0.49$ year), 6-7 years of age (G2, $6.42{\pm}0.53$), and 8-9 years of age (G3, $8.50{\pm}0.55$). The measurements times for the heart rate, blood lactate concentration, PCV, and Hb analysis were conducted before exercise (T0), shortly after exercise (T1), 15 min after exercise (T2), and 30 min after exercise (T3), respectively. Data was analyzed using an analysis of covariance (ANCOVA) for repeated measures with times and groups. Results: The results of the comparison depending on the passage of rest time after exercise suggest that the heart rate and blood lactate concentration of three groups at T2 significantly decreased compared to T1 (p < 0.001). PCV of the G2 and G3 groups were significantly decreased at T2 compared to T1 (p < 0.01). Hb values at G2 (p < 0.01) and G3 (p < 0.001) groups were significantly decreased at T2 as compared to T1. However, heart rate, blood lactate concentration, PCV and Hb level at T1 showed no difference in the comparison of horses from different age groups with the exception of G3 group in terms of heart rate. Conclusion: The physiologic and hematological responses of horses during recovery time after 2,500 m exercise with gallop were no significant difference among the groups. These data are useful as a response evaluation method for training of endurance horses.

This study was conducted to investigate the effects of Pleurotus eryngii fruiting body on blood glucose and cholesterol levels in streptozotocin-induced diabetic rats. Male Sprague-Dawley rats were used as experimental animals and experimental groups were divided into three groups, consisting of two control groups (diabetic and non-diabetic) and one P. eryngii group. Animals were fed experimental diets for 2 weeks. The values of died and water intake of P. eryngii group were lower than those of diabetic control group. The body weights of both groups after 2 weeks decreased by 18% as compared with initial values. The level of blood glucose decreased significantly by 16.9% in P. eryngii group as compared with diabetic control group, and there was a significant difference in glycosylated hemoglobin (GHb) level between both groups. The levels of total-cholesterol, LDL-cholesterol in plasma and atherosclerotic index were not significantly different between both groups. However the level of HDL-cholesterol increased significantly by 28% in P. eryngii group as compared with diabetic control group. These results suggested that fruiting bodies of P. eryngii exert blood glucose-lowering effect in streptozotocin-induced diabetic rats.

Objective: This study was conducted to report the glucose-lowering effect and safety of herbal extracts in patients with type 2 diabetes mellitus. Methods: We investigated 21 patients with type 2 diabetes mellitus who were administered Daeshiho-tang, Bojungikgi-tang, Jowiseunggi-tang, and Hoechunyanggyeok-san at Kyung-Hee University Korean Medical Hospital from 2014 to 2019. The hypoglycemic effect of the herbal extracts was assessed by comparing blood glucose levels, including fasting blood sugar (FBS) and 2-hour postprandial glucose (PP2) levels. For safety assessment, the effects of herbal extracts on liver and kidney function were analyzed by liver function tests, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and γ-glutamyltransferase (GGT), and kidney function tests, including blood urea nitrogen (BUN) and creatinine (Cr). Patients were stratified according to their glycated hemoglobin (<6.5 or >6.5) levels and the kind of herbal extract used for treatment. Results: After administration of herbal extracts, FBS and PP2 significantly decreased to 20.24 mg/dL and 35.0 mg/dL respectively. Subgroup analysis revealed that, regardless of the glycated hemoglobin level, FBS and PP2 were significantly reduced in both groups. The safety profile showed no significant difference before and after taking herbal extracts. Conclusions: Daeshigo-tang, Bojungikgi-tang, Jowiseunggi-tang, and Hoechunyanggyeok-san may show the further glucose-lowering effects on patients with type 2 diabetes mellitus who have already treated with anti-hyperglycemic agents.

The purpose of this study was to determine the effect of external biologger attachment methods on the blood parameters and attachment efficiency of spotted sea bass Lateolabrax maculatus (mean body weight 2630.8 g). The fish were tagged using four different external attachment methods with dummy biologgers: no attachment (control), anchor attachment (AA), monofilament attachment (MA), and silicon tube attachment (SA), each with triplicates. Blood indices and biologger attachment efficiency were assessed on days 1, 7, 14, 28, 56, and 84 after attachment. The concentrations of hematocrit, Na⁺, Cl^-, glutamic pyruvic transaminase and total protein, and the activity of superoxide dismutase in blood were not affected by the external attachment method of biologger. The concentrations of glutamic oxaloacetic transaminase (day 1 of attachment), hemoglobin (day 56) and total cholesterol (day 56 and 84) in AA group, the concentrations of glucose and cortisol (day 14) and total cholesterol (day 84) in MA group showed significantly higher than those of control (p<0.05). During the experiment period, the SA group had no differences from the control in all blood properties. The biologger attachment efficiencies of the AA, MA, and SA groups after 84 days were 0.0%, 33.3%, and 100.0%, respectively. These results indicate that the optimum external biologger attachment method under our experimental conditions is SA type.
