  • The role of oxidative stress in the initiation and the complication of diabetes was examined by monitoring blood glucose increase and oxidative DNA damage in rats treated with alloxan or streptozotocin (STZ). Oxidative DNA damage was assessed by quantitating 8-oxo-2'-deoxyguanosine ($oxo^8dG)$ excreted in urine and the $oxo^8dG$ accumulated in pancreas DNA. Both alloxan and STZ treatments resulted in an abrupt increase in blood glucose and significant increases in urinary and pancreatic $oxo^8dG$. Pretreatment of buthionine sulfoximine (BSO), a glutathione-depleting agent, slightly potentiated the increase of blood glucose and urinary $oxo^8dG$ in the alloxan- and STZ-treated rats. Furthermore, the BSO pretreatment caused significant amplification of pancreatic $oxo^8dG$ increase in the rats. On the other hand, pretreatment with 1,10- phenanthroline (o-phen), a chelator of divalent cations, showed different results between alloxan- and STZ-treated rats. The o-phen pretreatment completely blocked diabetes and the increase of $oxo^8dG$ by alloxan treatment, while it potentiated the increase of blood glucose and $oxo^8dG$ by STZ treatment. The results demonstrate that the causative effect of alloxan on diabetes may be the generation of reactive oxygen species through a Fenton type reaction, but that of STZ may not.

  • The present experiments were undertaken to produce the standard antiserum for equine blood typing. The following results were obtained through ISO and Hetero Immunizations of the horses whose blood typing was analysed in the Laboratory of Racing Chemistry of Japan. 1. Of the 21 combinations of ISO-immune, 17 horses were produced antibody (about 80%) 2. Antibody titers were increased from early 1 week to late 5 weeks and any antibody titers were not be obtained in spite of the using of adjuvant and 10 repeated injections in the other 4 horses. 3. High antibody titers were obtained within the earliest period in the Dd antigen but were not increased over 32 times in spite of 8~10 repeated injections in the antigen. 4. Antibody were easily produced in the Ca antigen of ISO-Immune but production of antisera were tailed due to abscence of absorbed blood cell. 5. Antibody titers of 1,024 times were obtained through 5 injections in the Ca of HeteroImmune 6. Of the produced 15 antisera (16 system), 13 antigen (5 system) were absorbed.

  • This study aims to develop a novel regimen for enhanced efficacy and reduced side effect in inhibiting platelet aggregation and blood coagulation by concurrent administration of triflusal and ibudilast as anticoaggulants. The result shows this combination of triflusal and ibudilast (300~500 ${\mu}M$, respectively) has additive effect in inhibiting platelet aggregation and blood coagulation over the administration of truflusal or ibdilast as a single treatment. This pharmaceutical composition is expected to be useful for the prevention or treatment of various diseases and symptoms, for example, ischemic heart disease, ischemic cerebral infarction, arteriosclerosis, and thrombosis caused by the insertion of a stent.

  • To understand the adaptational strategy of Korean chipmunks (Tamias sibiricus) to cold temperature, blood and serum properties, and thyroid gland activity of cold-exposed chipmunks were examined. The number of erythrocytes and hemoglobin concentration increased, but platelets decreased in cold-exposed chipmunks compared with warm chipmunks. Serum total protein levels increased at early phase of cold-exposure, and decreased thereafter. Plasma glucose levels showed a transitory increase in cold temperature. Although there was significant decrease in serum total thyroxine level in cold-exposed chipmunks, serum total triiodothyronine level changed little. Histological analysis of thyroid glands demonstrated decreased thyroid activity, suggesting that differences in the blood and serum properties between the warm and cold-exposed chipmunks may be due to the different metabolic strategy associated with cold temperature.

  • This study was to investigate the effect of calcium supplementation on the reduction of blood pressure in normotensive young adults. Fortyseven healthy college students(23 male and 24 female) were divided into Ca and placebo groups, and were orally given with calcium(1g/day, 2.5g as CaCO3) and placebo, respectively, for 20 weeks. Blood pressure was measured by Korotokoff method in seated position every two weeks. Average daily dietary calcium intakes of the subjects were 626-643mg in men and 513-552mg in women. Average initial level of serum calcium of the subjects belonged to normal range. 1. Both systolic and diastolic blood pressure(SBP and DBP) of Ca group showed significant continuously decreasing tendency from 6-8 weeks until final 20 weeks of the supplementation in both men and women. But placebo groups did not. Comparing with the basal value, reduction of SBP and DBP after 20 weeks were 6.53$\pm$4.30%(8.9mmHg) and 8.10$\pm$3.30%(7.4mmHg) in men, and 6.56$\pm$2.41%(8.1mmHg) and 7.33$\pm$3.75%(6.2mmHg) in women. The blood pressure lowering effect of calcium supplementation seemed to be greater in the subjects with higher basal SBP. 2. Serum calcium was significantly increased by calcium supplementation in both men and women, and showed significant negative correlation with SBP(r=-.213) and DBP(r=-.301) in women. Serum Ca/Mg ratio of Ca group was also elevated and showed significant negative correlation with SBP(r=-.174) and DBP(r=-.194) in total subjects. 3. Urinary excretion of Na did not show any significant changes by calcium supplementation in both men and women and showed no correlations with blood pressures.

  • This study was conducted to investigate changes of blood metabolites and enzyme activities at different slaughter ages of Hanwoo cattle. Blood samples were taken from six hundred thirty two steers (24~33 months of age) and one hundred twenty eight bulls (17~24 months of age) by venipuncture from caudal vein immediately prior to slaughter. Glucose concentrations were linearly increased (P<0.001) with increases of the slaughter age in steers, and blood urea nitrogen (BUN) concentrations were linearly decreased (P<0.001) with increases of the slaughter age in steers. Likewise, glucose and albumin concentrations in bulls were linearly decreased (P=0.009 and P<0.001, respectively) with increases of the slaughter age. BUN, cholesterol, triglycerides, and total cholesterol concentrations were linearly increased (P<0.001, 0.018 and 0.002, respectively), and creatinine concentrations were quadratically increased (P=0.009) with increases of the slaughter age. Activity of gamma glutamyltransferase (${\gamma}$-GT) and aspartate aminotransferase (AST) was linearly increased (P<0.001) with increases of the slaughter age in both steers and bulls, whereas alanine aminotransferase (ALT) was not affected by increasing slaughter age. In addition, the concentrations of ${\gamma}$-GT and AST were higher (P<0.05) for bulls than those of steers at 24 months of age. Increased levels of ${\gamma}$-GT and AST indicate impaired liver function; it may be associated with increases of concentrate level which is a concomitant of the extended fattening periods in Hanwoo feeding. In conclusion, the results in the present study may be one of the useful information for diagnosis of the metabolic disorder in Hanwoo cattle.

  • To investigate the effect of Feelch on alcohol metabolism, we measured both blood alcohol concentration in human and hepatic alcohol metabolizing enzyme activity in rats. The blood alcohol concentration in Feelch-ingested group was significantly lower than that in water-ingested group at 0, 40, and 80 minute after alcohol intake. The blood alcohol concentration between male and female taken 300ml of $21\%$ alcohol showed the significant differences; the peak value of blood alcohol concentration in male and female were $0.083\pm0.014\%\;and\;0.108\pm0.018\%$, respectively. In alcohol-fed rats, aldehyde dehydrogenase (ALDH) activity was significantly increased, whereas alcohol dehydrogenase (ADH) activity was not changed. In both Feelch-fed group and Feelch plus alcohol-fed group, ADH and ALDH activity were significantly increased as compared with each control group. Feelch decreased phospholipase $A_2$ activity and lipid peroxidation in hepatic tissue and activities of serum aminotransferases as compared with control. These results suggest that Feelch may have a hepatoprotective effects and this is likely due to lower blood alcohol concentration via the increment of hepatic ADH and ALDH activity.

  • Purpose: The purpose of this study was to examine relationships among blood glucose, HbA1c, and self management comparing these with general and illness characteristics of subjects with Type II Diabetes living in the community. Methods: Using a comprehensive survey developed for the study, data were collected from 82 type II diabetes patients who were registered at five community health departments. The variables of self management, blood glucose and HbA1c were assessed by nurses. Data were analyzed with descriptive statistics including t-test, ANOVA and Pearson's correlation coefficient to compare self management and level of HbA1c by subject's general and illness characteristics and to examine the relationships among variables. Results: About 73.2% of the subjects' HbA1c were 7.0% or higher and 54.9% of subjects' blood glucose were 200 mg/dL or higher. The level of self management was moderate. Most frequently perceived reasons for failure of blood glucose control were dietary failure (32.9%). There was significant relationship between self management and HbA1c(r=-.223, p=.040). The mean score of self management were higher among female (t=-2.37, p=.021), who are not on diabetes medication (t=6.70, p=.011). Conclusion: Comprehensive intervention is needed to improve dietary self management, especially for male and those who is on diabetes medication.
