The purpose of this study was to investigate the effects of Natto supplementation on lipid metabolism in rats. Male rats were fed on casein(CON group), steamed soybean(SS group), conventional Natto(N-1 group), garlic(2%) added Natto(N-2 group), red pepper oleoresin(0.2%) added Natto(N-3 group) and galic(2%) and red pepper oleoresin(0.2%) added Natto(N-4 group) as a protein source for 4 weeks. Serum and liver cholesterol levels were significantly lower in the experimental groups than in the control group. Especially, dietary N-2, N-3 and N-4, compared with CON, reduced markedly the concentration of serum cholesterol. The concentration of serum HDL-cholesterol was higher markedly in the N-4 group than in the control group. The concentration of serum triglyceride was significantly lower in the N-1, N-2, N-3 and N-4 groups than in the control group. Garlic and red pepper added Natto fed groups(N-2, N-3, N-4) showed more excreion of fecal bile acid when compared with those values of casein fed group. The results indicate that spice added Natto supplementation may have more beneficial roles in lipid metabolism through reduced cholesterol levels and increased fecal bile acid excretion.

An experimental study on the selenium effects on toxicity of lead (4ppm intraperitoneal injection) in adult male rats of Spragne-Dawley strain was performed. This study was carried out to reveal the selenium effects concerning treatment and prevention of lead intoxication and differences of the selenium effects according to the administration method between oral and subcutanous. The changes of body weight, liver and kidney weight per body weight, hemoglobin values, hematocrit values, TBA values in serum, and $\delta$-ALAD activity in blood were determined. The results were as follows 1. There were no significant differences among groups about the change of body weight. 2. In the liver weight per body weight, the group of Pb administration after the oral administration of selenium was significantly high, different from the group of Pb administration alone (p < 0.05). 3. There .were no significant differences among groups about the kidney weight per body weight. 4. On the hemoglobin values, the group of Pb administration with selenium was significantly high,different from the group of Pb administration alone (p < 0.05). 5. There were no significant differences among groups about the hematocrit values. 6. On TBA values in serum, all the selenium treated groups were significantly low different from the group of Pb administration alone (p < 0.01). 7. On $\delta$-ALAD activity, all selenium treated groups were significantly high different from the group of Pb adminsitration alone (p < 0.01). Considering from the results of this experiment, selenium seems to reduce Pb toxicity and preventive administration of selenium seems to be also effective. And the difference of selenium effect according to the administration method between oral and subcutaneous could not be found.

Present experiments were undertaken for the purpose of clarifying the effect of repeated halothane anesthesia on the liver and kidney function. Nine mongrel dogs were divided into three groups. The group one dogs were anesthesized once(control group) and the other two groups twice and trice respectively on 10th day of previous anesthesia experimental groups. Hematological examinations and blood chemical assays were undertaken during the period from one hour to 10 days after the anesthesia. From these experiments fellowing results were obtained; 1. No significant changes of erythrocyte count were recognized in both the control and experimental groups after the halothane anesthesia. 2. The total leukocyte counts of experimental groups showed significant decrease on one hour and subsequent increases after the anesthesia. 3. No significant changes were observed in SGOT, SGPT, ALP, BUN and serum glucose values in both the control and experimental groups. 4. The total serum protein values showed a tendency to decrease on the first hour of halothane anesthesia in both the control and experimental groups. From these results it may be concluded that the repeated halothane anesthesia done 10th day of previous anesthesia do not affect the liver and kidney function in dogs.

The present study was conducted to investigate the effect of nutrition education program on anthropometric values and boichemical index in obese children who live in Gumi city. The subjects were 16 obese boys, 20 obese girls with obesity index over 130 and 36 of their parents. The nutrition education was carried out by the professional personnel such as doctors, professors, and dietitians. The children were provided with well-balanced lunch meals and had 40min-lectures on the reasonable weight management, 40 min-games and also had regular exercises (stretching, swimming) for 90 mins everyday during 2weeks of the program. The parents had 90 min-lectures on childhood obesity, diet therapy, behavior modification, and exercise for 6times. After the program, obesity index, BMI, % body fat were significantly decreased (p < 0.05) in boys and obese index, BMI, % body fat and WHR were significantly decreased (p < 0.05) in girls. Blood cholesterol and TG levels of girls were significantly decreased (p < 0.05). These findings show that the well-designed nutrition education program for obese children can be an effective approach to help them to improve their anthropometric values and biochemical index.

Objectives : The authors evaluated the effects on renal function of workers chronically exposed to low-level organic solvent mixtures. Methods : The authors measured the level of urine ${\beta}2$-microglobulin(${\beta}2$-MG) and microalbumin as biochemical markers of renal function and damage in 29 male workers exposed to organic solvents for more than five years and compared their results with those of 30 male office clerks as a reference group. Results : 1. The mean values of hemoglobin, hematocrit, SGOT, SGPT, ${\gamma}$-GTP were all within normal limits and there was no significant difference, except for hemoglobin(p<0.01), between exposed and reference group. 2. The values of BUN and serum creatinine were within reference limits and there was no significant difference between exposed and reference group. 3. The difference of mean values of urine microalbumin corrected by urine creatinine were statistically significant (p<0.01), but those of urine ${\beta}2$-MG was not. 4. There were no correlation of urine hippuric acids with BUN, serum creatinine, urine microalbumin and ${\beta}2$-MG. 5. There were no significant difference of BUN, serum creatinine, urine microalbumin and ${\beta}2$-MG upon work duration. Conclusions: It is assumed that chronic low-level organic solvent exposure in these workers shows early renal dysfunction, glomerular changes. The result corresponds to previous studies showing the relationship between hydrocarbon exposure and glomerulonephritis. For evaluation of impairment on kidney tubules, we need further study using more precise markers and long-term follow-up.

The object of this study is to investigate the toxicity of fenvalerate [(RS)-$\alpha$-cyano-3 -phonoxybenzyl-(RS)-2-(4-ch1orophenyl)-3-methylbutyrate] and the effect of carbaryl on the toxicity of fenvalerate. Rats were treated with fenvalerate (50 mg/kg, 100 mg/kg), carbaryl (50 mg/kg, 100 mg/kg) or mixtures of the two compounds (fenvalerate+carbaryl: 50 mg/kg+50 mg/kg, 50 mg/kg+100 mg/kg) by oral administration for 1~3 weeks. Control groups were treated with corn oil. The experimental results were summarized as follows. 1. LD$_{50}$ values of fenvalerate and carbaryl in male rats were 385 mg/kg and 625 mg/kg respectively. When 50 mg/kg and 100 mg/kg of carbaryl were administratrd, LD$_{50}$values of fenvalerate were 265 mg/kg and 225 mg/kg respectively. 2. Biochemical parameters such as ALT, LDH and glucose in serum were much more increased in the groups treated with mixture than the groups treated with either one of fenvalerate or carbaryl. 3. The groups treated with carbaryl and mixture for 3 weeks, the contents of cytochrome P-450 in the liver were significantly increased. In renal microsomal fractions, however, no significant changes of drug metabolizing enzyme activities were observed. 4. The activities of aniline hydroxylase in hepatic microsomal fractions were increased in the groups treated with fenvalerate and mixture and activity was much more increased in the groups treated with mixture. 5. The activities of ATPase in the groups treated with fenvalerate were decreased than that of groups treated with mixture. TBA values and the activity of glucose-6 -phosphatase in the liver were not significantly changed. 6. In mixture treated groups, the activities of cholinesterase in serum and in the liver were more decreased than those of carbaryl treated groups. The activities of carboxylesterase in serum in the liver were slightly increased in mixture treated groups, but in fenvalerate treated groups, the activities of carboxylesterase were much more increased than those of control groups. 7. As a result of this study, when carbaryl was as the synergist of fenvalerate, carbaryl inhibited the activities of esterases, so the toxicity of fenvalerate was increased.sed.

Purpose: The liver is the second most common organ injured by blunt abdominal trauma. The purpose of this study was to determine the utility of liver transaminase in screening blunt abdominal trauma patients for traumatic liver injury. Methods: We retrospectively reviewed the medical records of 231 patients who sustained blunt trauma and were at risk for traumatic liver injury between June 2009 and August 2010. All of them underwent a focused assessment with sonography for trauma (FAST) and abdominal computed tomography (CT). Based on the diagnosis of abdominal CT, patients were divided into two groups: group I with liver injury and group II without liver injury. We compared the two groups and calculated the sensitivity, the specificity and the predictive values of serum aspartate aminotransferase (AST) and serum alanine aminotransferase (ALT) by using multiple cutoff values. Results: Of 231 patients with no abdominal free fluid in the FAST, 33 had traumatic liver injury on abdominal CT. The mean AST and ALT levels in group I (311.6 IU/L and 228.1 IU/L, respectively) were significantly higher than the values in group II (48.4 IU/L and 35.6 IU/L, respectively). The cutoff to distinguish liver injury is 60 IU/L for AST and 58 IU/L for ALT, with 93.8% sensitivity and 79.8% specificity for AST, and 90.6% sensitivity and 87.4% specificity for ALT. Conclusion: We recommend that all patient with suspected blunt abdominal trauma be evaluated using serum liver transaminase as a screening test for liver injury even though no abdominal free fluid is shown on the FAST. If AST > 60 IU/L and/or ALT > 58 IU/L, abdominal CT was useful to confirm liver injury in this study.

Reference interval is critical for interpreting laboratory results, monitoring response to therapy and predicting the prognosis of the patients in clinical settings. The aim of the present study was to update established reference intervals for routine hematologic and serum chemistry values for a population of clinically healthy dogs (range, 1-8 years) seen in an animal hospital. Blood was obtained by venipuncture while animals were physically restrained, and samples were analyzed for 9 chemistries on MS9-5H (Melot Schloesing Lab, France) and 6 hematology on Vet Test 8008 (IDEXX, USA). Data from 105 dogs (52 males and 53 females) for hematology and 113 dogs (37 males and 76 females) for chemistry were used to determine reference intervals using the parametric, nonparametric and bootstrap methods. Prior to analysis, all parameters were tested for normal distribution using Anderson-Darling criterion. Of the 9 biochemical analytes, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, creatinine, total protein, and glucose concentrations did not fit normal distribution for both original and transformed data. All but eosinophil count satisfied normal distribution for either original or transformed data. Parametric method can be used for original cholesterol concentrations, RBC, WBC, and neutrophil counts. This technique can also be used for power-transformed values of blood urea nitrogen concentrations and for logarithm of lymphocyte and monocyte counts. Non-parametric or bootstrap method was the preferred choice for the remaining 7 biochemical parameters and eosinophil count as they did not follow normal distributions. All three statistical techniques performed in similar reference intervals. When establishing reference intervals for clinical laboratory data, it is essential to assess the distribution of the original data to increase the accuracy of the interval, and non-parametric or bootstrap methods are of alternative for the data that do not fit normal distribution.

Effects of repeated administration of diminazene aceturate (Hoechst Veterin r GmbH. Ger- many) that has been introduced as effective compound against Babesiosis and trppanosomiasis were investigated in dogs experimentally infacted with Babesia gibsoni. Adull mongrel dogs of both sexes were inoculated will nonpreserved infected blood and then maintained chronic anemia. A single dose of diminazene aceturate of 7mg/kg b.w. was administrated intramnuscularIy on day 7.1 arid ,7. Clin- ical and hcmatological findings following inoculation and medication were observed and 7enlm bio chemical analysis also was monitored. Parasitemia was detected between 3 and 6 days after inoculation. The rate of parasitized erythrocytes,1 in peripheral blood reached the peak on the 13th day and was maintained the percentage of 0.1 to 1.0 until the medication of diminazene aceturate. RBC was significantly (p<0.01) decreased on the 3rd day and then kept on decreasing. The lowest value was observed on the 16th day. WBC remained generally within normal ranges. PCV revea1ed the sig-nificant (p<0.01) decrease within the range of 24-27% and platelet was significantly (p<0.05) decreased during the period. Senum chemical values (ALT, AST. total bilirubin. LDH BUN, area- tinine, total protein. albumin and glucose) were within normal ranges during the experimental period. Serum CPK values were significantly (p<0.01) increased on the 3rd day. There was no clinically, sig-nificant difference in a single dose of diminazene aceturate of 7 mg/kg b.w. But the administration of diminazene aceturate of 14 mg/kg b.w. revealed vomiting and anorexia and one dog died in 30 hours after administration. The administration of 14mg/kg b.w. resulted in vomiting, salivation, actor- exia, tremor of head and involuntary movement and one dog died in 27 hours after administration. WBC, RBC, PCV and Platelet values were no significant difference and hematological findings revealed persistent anemia and thrombocytopenia during chronic anemia after inoculation. AST activity its was significantly (p<0.01) increased 11\\`from 3 days after medication and AST activity was on the same trend. Serum CPK activity revealed significant (p<0.01) increase within 6 hors)\\`s after every administration and decreased in 48 howl·s after administration.
