The present study was undertaken to clarify the changes in blood chemical values of indigenous Korean striped calves according to age. Blood samples were collected from 15 calves (8 females and 7 males) reared at the Gyeongsangbukdo Livestock Research Institute and the levels of various chemicals in serum were analyzed. The mean total protein, albumin and globulin concentration in calves increased from 2 weeks after birth, and the levels in females were higher than those in males at 8 weeks after birth. The mean glucose concentration increased significantly at 2 weeks after birth. The mean blood urea nitrogen concentration increased from 2 weeks after birth, whereas the mean creatinine concentration decreased significantly from 2 weeks after birth. The mean uric acid concentration increased gradually from 2 weeks after birth. The mean glutamic oxaloacetic transaminase and glutamic pyruvic transaminase concentration increased significantly from 2 weeks after birth. The mean total bilirubin concentration tended to decrease from 2 weeks after birth. The mean triglyceride, total cholesterol and high density lipoprotein cholesterol concentration increased significantly from 2 weeks after birth. In conclusion, the data obtained from this study may be valuable as a standard for interpreting results of biochemical analyses in indigenous Korean striped calves.

This study was carried out to evaluate the effects of Dochetang for the treatment of chronic diarrhea in a 4 months-old-female Korean native calf. The calf was presented to the Wow Animal Clinic, Iksan with the history of chronic diarrhea for several weeks. The feces test did not reveal the presence of the parasites or microbes causing diarrhea in calf. The blood test was also negative to the virus that causes of diarrhea in calf. Adminstration of parenteral antibiotics resulted in improvement of the condition temporarily but diarrhea was recurred again after 2-3 weeks. Then the calf was treated with Dochetang administered orally once a day in an empty stomach for 15 days. Feces was significantly reduced in moisture on 7 days after initial treatment. On 9 days after initial treatment, the calf had normal appetite and defecation in physiological conditions. Blood samples were collected before administration and on 1, 2 and 3 weeks after initial administration of Dochetang for hematology and biochemistry. A significantly differences were observed in the white blood cell (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), albumin (ALB), glutamic pyrubic transaminase (GPT), inorganic phosphorus (IP) and magnesium (Mg), while no significant differences were seen in the red blood cell (RBC), hemoglobin (Hb), hematocrit (HCT), platelet (PLT), glucose (Glu), total protein (T-pro), glutamic oxaloacetic transaminase (GOT), blood urea nitrogen (BUN) and creatine (CRE). This study suggests that Dochetang administration can be a successful alternative therapeutic agent in instead of antibiotics for the treatment of chronic diarrhea in calves.

Effects of repeated physical exercise on the carbon tetrachloride ($CCl_4$) hepatotoxicity were examined in adult female rats. Rats were introduced into a cylindrical rotating cage and forced to exercise for 1 hr each day, 6days/week, for 5 consecutive weeks at a speed starting from 10m/min, increased by 1m/min per day until the speed reached 27m/min. Significantly less body weight gain was observed in the exercise group suggesting that physical fitness had been induced in these animals. Eighteen hours following termination of the last exercise bout rats were treated with $CCl_4$(2 mmol/kg.ip). The $CCl_4$-induced heptotoxicity was significantly potentiated in the repeated exercise group compared to the resting sedentary animals as determined by changes in serum sorbitol dehydrogenase (SDH), glutamic oxaloacetic transaminase(GOT), glutamic pyruvic transaminase (GPT), and glucose-6-phosphatase(G-6-Pase) activities when measured 24hrs following the $CCl_4$ treatment. Hepatic drug metabolizing activity was determined in order to elucidate the underlying mechanism of potentiating action of the $CCl_4$ hepatotoxicity induced by repeated physical exercise. Repeated exercise increased the hepatic microsomal cytochrome P-450 contents and aminopyrine N-demethylase activity. The results suggest that the potentiation of $CCl_4$ hepatotoxicity by repeated exercise is associated with induction of the mixed function oxidase (MFO) enzyme system mediating the metabolism of $CCl_4$ to its active metabolite(s).

This research analyzed the hematological index and health related habits such as alcohol drinking, smoking and exercise, by classifying 539 middle-aged men (age: 40 - 59) into a normal weight group, an overweight group and an obese group, according to BMI (body mass index). As a result, 33.6% (n = 181) of subjects had a BMI of 23 or less and 30.2% (n = 163) were overweight and 36.2% (n = 195) were obese (BMI > 25). The average systolic/diastolic blood pressures of total subjects were 130.96mmHg and 80.38mmHg, respectively. And the average pressure of normal subjects was 126.85/77.57mmHg, which was significantly lower than in overweight and obese subjects. Diastolic blood pressure shows significant differences among the three groups. The overall average cholesterol level of normal subjects was 193.81mg/dl, which was significantly lower than those in overweight subjects. Those in obese subjects were significantly higher than in overweight subjects. The GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyrutic transaminase), ${\gamma}$-GTP (gamma-glutamyl transpeptidase) levels of obese subjects were significantly higher than in the overweight subjects. Frequency of alcohol drinking showed no significant difference among the groups. The smoking ratio in the obese group was higher than in the normal and overweight groups. The ratio of smokers was 53.1 %, and the alcohol drinking ratio was 81.0% of the total subjects. The frequency of drinking showed significant correlations with systolic blood pressure (p < 0.05) and diastolic blood pressures (p < 0.01) and ${\gamma}$-GTP (p < 0.01). The duration of smoking showed a negative correlation (p < 0.01) with diastolic blood pressure, total cholesterol and ${\gamma}$-GTP. On the other hand, exercising frequency showed negative correlations with blood glucose, ${\gamma}$-GTP and GPT(p < 0.01). These hematological indices were correlated with health related habits such as alcohol drinking, smoking and lack of exercise, and to be the cause of chronic diseases. Therefore, proper nutritional education is needed to establish advisable health related habits to maintain proper body weight. (J Community Nutrition 8(2): 63-68, 2006)

The effects of chronic chitosan salt supplementation on the systolic (SBP) and diastolic blood pressure (DBP), and physiological parameters were investigated in healthy male and female adult. Chitosan salt was conducted by measuring various health-related factors such as body composition, plasma $Na^+$, $Cl^-$, lipid, and lipoproteins profiles, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) activity. Chitosan salt supplementation no significant differences before and after supplement in body composition variables and in SBP and DBP in either male or female. Plasma sodium and chlorine concentration no significant changes during chitosan salt supplementation, and no significant difference between two genders. Plasma GOT and GPT activity no different before and after supplement in either male or female. GOT activity significantly higher for male before supplement (p<0.05), and 2 weeks after supplement (p<0.01). The lipid and lipoproteins profiles of plasma no significant changes during chitosan salt supplementation in either male or female subjects. In summary, the chronic intake of chitosan salt did not affect the SBP or DBP, and posed no health risks.

In human medicine, circulating microRNAs have been successfully utilized as early biomarkers for various abnormalities and disease states. Vertebrate miR-122 is a liver-specific microRNA which is expressed almost solely in hepatocytes and plays an important role in the regulation of hepatocyte function. In this study, to evaluate the potential utility of circulating miR-122 as a biomarker for liver injury in olive flounder (Paralichthys olivaceus), fish were orally intubated with two doses of acetaminophen (500 mg/kg or 1.000 mg/kg of body weight), and the expression of miR-122 in serum was quantified using real time-PCR. Histological change in liver, and the enzymatic activity of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were also analyzed. The results showed that miR-122 was higher in acetaminophen administered groups compared to control group. The histopathological effect of acetaminophen on olive flounder liver was not distinct. The serum level of GPT and GOT was increased within 2 folds compared to control group by acetaminophen administration. However, the serum miR-122 level was increased more than 3 or 4 folds compared to the control group by administration of 1000 mg/kg of acetaminophen. These results suggest the possible use of miR-122 as an indicator of liver injury in olive flounder, even when histopathological effects are not distinctive.

In this study, we intended to evaluate the modulatory effects of natural products, ${\beta}-carotene$, aloesin and semiessential amino acid, taurine on the toxicitiy of paraquat. In the taurine treated groups, serem glutamic oxaloacetic transaminase (s-GOT), serem glutamic pyruvic transaminase (s-GPT). blood urea nitrogen (BUN), creatinine, malondialdehyde (MDA), alkaline phosphatase (ALP) activity in serum and MDA, ALP activity, collagen in lung tissue were decreased to the normal values. In the aloesin treated groups, s-GPT, BUN, creatinine, MDA level in serum were decreased to the normal values significantly. In the ${\beta}-carotene$ treated group, only s-GPTactivity was reduced to the normal values. In the lung tissue of taurine treated groups, MDA value, G-6-phosphatase activity and collagen synthesis were recovered to the normal valuse and ALP activity was increase about 40%. From these results, we concluded that taurine is an effective agent to inhibit the pulmonary and internal organs toxicities induced by paraquat and the inhibition effects of taurine are due to remove free radicals directly.

A limited number of studies have been conducted on the bioactivity of Callophyllis japonica (C. japonica), which is a red seaweed that is traditional in the oriental diet. In this report, the hepatoprotective effect of C. japonica was studied in a carbon tetrachloride $(CCl_4)-induced$ hepatotoxicity model in rats. A single intraperitoneal injection of 1.25 ml/kg of 20% $CCl_4$ in olive oil produced an elevated level of serum glutamic pyruvic transaminase (SGPT) and increased enzyme activity of serum glutamic oxaloacetic transaminase (SGOT). Pre-treatment with C. japonica (150 mg/kg/d) for 3 days in $CCl_4-injected$ rats reduced the levels of SGPT and SGOT compared with control levels (P < 0.05), while higher doses (300 and 600 mg/kg) were ineffective. The administration of C. japonica (150 mg/kg/d) for 3 days after the $CCl_4$ injection in rats was ineffective at reducing SGPT and SGOT. The histopathological findings in each group largely agreed with the biochemical data. The results of this study support the suggestion that C. japonica has a hepatoprotective effect on chemical-induced liver injury.

Objectives: This study was designed to evaluate the anti-diabetic effects of Spargaium stoloniferum Buchanan-Hamilton (Sparganii Rhizoma, SR) extract on diabetic rats. Methods: Diabetes was induced with Sprague-Dawley rats by high fat/high sucrose (HF/HS) diet for 4 weeks and injection of a single low dose of streptozotocin (STZ; 35 mg/kg). SR water extract at 500 mg/kg was orally administrated once a day for 4 weeks. Body weights, food and water intakes and urine volumes were measured. The levels of glucose, insulin, total cholesterol, glutamic oxaloacetic transaminase and glutamic-pyruvic transaminase (GPT) were measured in the sera of rats. Histological changes were observed in pancreas, liver, and kidney tissues by H&E staining. Results: The administration of Sparganii Rhizoma extract at 500 mg/kg in diabetic rats did not shown a significant difference in body weight changes and GPT levels, but showed meaningful changes in an increase of urination volume, and decrease of serum glucose and insulin levels. Total cholesterol and GPT levels were also significantly decreased after SR extract administration in diabetic rats. Furthermore, the abnormal changes of pancreas, liver and kidney were also improved by Sparganii Rhizoma extract administration. Conclusions: These results indicate that SR extract can improve HF/HS-diet and STZ-induced diabetic damages in rats through inhibition of the blood glucose and insulin increase.

Obesity is known to be strongly associated with cardiovascular disease and cancer, the leading causes of mortality worldwide, and develops owing to interactions between genes and the environment. DNA methylation can act as a downstream effector of environmental signals, and analysis of this process therefore holds substantial promise for identifying mechanisms through which genetic and environmental factors jointly contribute to disease risk. Global DNA methylation of peripheral blood cells has recently been proposed as a potential biomarker for disease risk. Repetitive element DNA methylation has been shown to be associated with prominent obesity-related chronic diseases, but little is known about its relationship with weight status. In this study, we quantified the methylation of Alu elements in the peripheral blood DNA of 244 healthy women with a range of body mass indexes (BMIs) using pyrosequencing technology. Among the study participants, certain clinical laboratory parameters, including hemoglobin, serum glutamic oxaloacetic transaminase, serum glutamic- pyruvic transaminase, total cholesterol, and triglyceride levels were found to be strongly associated with BMI. Moreover, a U-shaped association between BMI and Alu methylation was observed, with the lowest methylation levels occurring at BMIs of between 23 and $30kg/m^2$. However, there was no significant association between Alu methylation and age, smoking status, or alcohol consumption. Overall, we identified a differential influence of BMI on global DNA methylation in healthy Korean women, indicating that BMI-related changes in Alu methylation might play a complex role in the etiology and pathogenesis of obesity. Further studies are required to elucidate the mechanisms underlying this relationship.
