The objective of this study was to determine changes in serum hormone concentrations, blood chemical values and recovery rate of in vivo embryos during the estrous cycle following super-ovulation treatments in Jeju black cows. Superovulation was induced by subcutaneous administration of FSH twice a day for 4 days. Serum hormones were assayed by radioimmunoassay (RIA) and blood chemical values were analyzed by blood analyser system. Embryos were collected from all treated black cows using nonsurgical technique on day 7 after artificial insemination (AI). The results of this study were summarized as follows: 1. The progesterone concentrations were $7.2{\pm}3.8ng/ml$ at day -11 and $0.3{\pm}0.1ng/mL$ at day 0 (Day 0 is the first day of AI). The estradiol concentrations were $10.6{\pm}4.48pg/ml$ at day -11 and $15.0{\pm}2.2pg/ml$ at day 0. The lowest level of progesterone was measured at day 0. The highest levels of estradiol was measured at day 0. 2. The blood chemical values of treated black cows were no significant differences in normal cow values. 3. Sixty two embryos were collected in 12 black cows. Among the collected embryos, 37 embryos (59.7%) could be transferred into recipients. These results would be used as the basic informations for changing patterns of hormonal level and blood biochemistry in Jeju black cow with superovulation.

Korean goral (Neamorhedus caudatus) is registered as a natural monument number 217 by South Korea Cultural Heritage Administration. It is also recognized as the endangered species I by Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). In this study, blood samples of Korean goral were collected to make reference intervals. Blood sampling was conducted on 19 numbers of Korean gorals (ten females, nine males), which were reared in Korean Goral Restoration Center. For total samples, the reference intervals of hematological parameters were: white blood cell $7.69{\sim}10.87K/{\mu}{\Lambda}$; hematocrit 36.73~46.18%; red blood cell $10.72{\sim}12.86K/{\mu}{\Lambda}$; hemoglobin 12.79~15.14 g/dL; mean corpuscular volume 33.15~36.75 fL; mean corpuscular hemoglobin 11.53~12.23 pg; mean corpuscular hemoglobin concentration 32.64-35.91 g/dL and red blood cell distribution width 39.2~43.46%. For total samples of each parameters, the following results were obtained for serum biochemistry: glucose 111.81~153.77 mg/dL; blood urea nitrogen 22.35~28.91 mg/dL; creatine 1.22~1.84 mg/dL; phosphate 4.57~6 mg/dL; calcium 8.7~9.1 mg/dL; total protein 6.53~6.92 g/dL; albumin 3.1~3.48 g/dL; globulin 3.26~3.62 g/dL; alanine aminotransferase 56.7~158.56 U/L; aspartate aminotransferase 230.35~473.06 U/L; alkaline phosphatase 178.06~332.47 U/L; gamma-glutamyl transpeptidase 131.6-~181.24 U/L; total bilirubin 1.47~2.12 mg/dL; cholesterol 46.48~71.52 mg/dL; amylase 16.3~26.03 U/L; sodium 150.43~153.88 mmol/L; potassium 3.98~4.6 mmol/L and chlorine 109.48~113.26 mmol/L. The ranges of values were similar campared to previous studies except in the case of RDW value, which showed higher range than the RDW value of a previous study.

Purpose In nuclear medicine blood tests, hemolysis samples are considered as inappropriate sample and are recommended not to be used for blood test. So, the lab are required to collect the blood again in the blood collection room However, The effect of hemolyzed samples on radioimmunoassay has not studied yet. This study was designed to evaluate effects of hemolysis on radioimmunoassay. Materials and Methods The kit manuals of 23 test items were reviewed to confirm whether hemolyzed samples were used. The subjects were 19 general applicants(male : 9, female : 13) and the samples were collected by each two SST tubes, one tube was obtained by centrifugation normally, and the other was obtained hemolyzed sample by centrifugation after external shock. It has been known that highly hemolyzed samples can affect the test results, so the test was performed using the severe hemolyzed sample. The test was performed for each test item using 23 normal serum and hemolysis serum, and SPSS19 program was used for statistical comparison of the test result. Results There was no significant difference between normal serum and hemolysis serum in 21 of 23 test items, but the results of insulin and C-peptide were significantly different(P<0.05). Conclusion It has been known that hemolysis in blood samples can affect the results of biochemical and hematological test, However, hemolysis effect is relatively low. Similarly, this study showed that hemolysis had not much effect on most of immunological radioimmunoassay except for some tests. Therefore, it is thought that the demand for re-collection due to hemolysis will be reduced in the laboratory, which will improve the work process of the laboratory.

This study aimed to investigate the effect of subjective factors (figure recognition and stress) and objective factors (blood biochemical parameters) on body mass index by gender difference in Korean adults. This study analyzed 3,343 subjects older than 20 years according to gender using the Sixth Korean National Health and Nutrition Examination Survey database. Specifically, male subjects had higher body mass index than female subjects (p < .001) and were more frequent in the obese group. Female subjects had higher stress and platelet score than male subjects (p < .001). Male subjects had significantly higher white blood cell counts (p < .001). The factors affecting the occurrence of obesity by gender difference was highly associated with subjective figure recognition (95% CI = 0.026~0.045, p < .001), stress (95% CI = 0.487~0.925, p = .015) and white blood count (95% CI = 1.232~1.392, p < .001) in females. These findings demonstrate a gender-specific difference in recognizing subjective factors and especially the objective factors of white blood cells and platelets affecting obesity. These results can be used for obesity education or fundamental data for establishing a nursing arrangement program for Korean adults.

This study was conducted to estimate the incidence and the degree of cigarette smoking and drinking among working men, and then to investigate the effects on blood pressure, various hematological indices and blood chemistry. The sample consisted of 2,287 male workers who had undertaken a general health check-up during the two-year period from January, 2000 to December, 2001. Such factors as blood pressure, blood glucose, lipid profiles, and liver function tests were determined and then analyzed with respect to the subjects smoking and/or drinking status. The major findings from this study are: 1. The drinking and smoking status have shown that 52.7% of participants were in the habit of both drinking and smoking while 11.6% were not associated with either. On the other hand 25.4% were involved only in drinking and 10.2% only in smoking. In the group smoking over 21 cigarettes per day over 30, the age group occupied the largest proportion at 20.1%. 2. Regarding the relationship between smoking and/or drinking status, and blood pressure, hematology and blood chemistry, the smoking and/or drinking group had significantly higher levels of blood pressure, both systolic and diastolic, Hb & Hct, TG, LDL-C, SGOT, and ${\gamma}$-GTP, than the non-smoking and/or non-drinking group. But HDL-C was significantly lower in the smoking group and significantly higher in the drinking group than the non-smoking/non-drinking group. 3. Regarding amount smoked, a larger number of cigarettes per day was significantly associated with the higher levels of blood pressure, systolic and diatolic, TG, TC, LDL-C, Hb, Hct, and ${\gamma}$-GTP. As for the amount druck, an increasing amount of alcohol intake was associated with rising levels of blood pressure, systolic and diatolic, TG, TC, LDL-C, HDL-C, Hb, SGOT, and ${\gamma}$-GTP. 4. Regarding the correlation among all the variables stated above, the smoking and drinking amount was shown to be in the positive correlation with blood pressure, both systolic and diastolic, TG, TC, Hb, and ${\gamma}$-GTP. On the contrary, LDL-C and HDL-C was in a positive correlation only with the amount drunk amount, and Hct only with the amount smoked. 5. As with systolic and diastolic blood pressure, the odds ratio of the smoking group was 2.35 and 2.58 compared to the non-smoking/drinking group. whereas it was 1.47 and 1.75 in the smoking/drinking group. Concerning serum lipids, the smoking/drinking group had 1.97 times the levels of TG in the non-smoking/non-drinking group, though the smoking group had 1.55 times the levels of HDL-C in the non-smoking/non-drinking group. As with liver function test results, the drinking group had 2.50 times and the smoking/drinking group had 4.41 times the levels of ${\gamma}$-GTP in the non-smoking/drinking group. respectively. The above results revealed that smoking and alcohol intake were effected the results of blood pressure and laboratory tests. Specifically, not only the smoking/drinking group but also those only smoking or only drinking were not as desirable as the non-smoking and non-drinking group to the results of blood pressure and laboratory tests.

Acetaminophen (APAP) and gentamicin are widely used for many patients, but little in-formation is available regarding the combined effects of APAP and gentamicin. This study was aimed to investigate the potent nephrotoxicity following combined-treatment with APAP and gentamicin. Serum biochemical parameters and histopathological changes in the kidney were observed in female SD rats after continuous daily treatment with either 600 mg/kg/day APAP, and/or 300 mg/kg/day gentamicin for 3 days, and compared with saline sham-treated control animals. APAP and gentamicin combination-treated rats exhibited inconsistent increasing tendency in blood urea nitrogen (BUN) by 96 hours after the last treatment, compared to control or the animals treated with each drug. The relative kidney weights were also increased. Histopathological findings of kidneys revealed that necrosis of proximal convoluted tubules were higher in rats treated with APAP and gentamicin combination than the rats treated with each drug alone. These results suggest that combination use of both drugs have more severe nephrotoxicity than treating each drug alone.

Experiments were performed on mice to investigate the effect of Panax ginseng petroleum ether fraction on the immunotoxicity of lead acetate. Lead acetate was administered in the drinking water and ginseng p-ether fraction was injected intraperitoneally, Mice were sensitized and challenged with sheep red blood cell. Humoral immune responses were evaluated by antibody production and Arthus reaction. Pathotoxicological influences were measured by serum protein, alkaline phosphatase and total cholesterol. The weight of liver, spleen and thymus were measured. Lead acetate exposure significantly decreased hemagglutination titer, hemolysin titer, Arthus reaction, spleen and thymus weight. Ginseng p-ether fraction administration significantly restored or potentiated reduced humoral immune response, spleen and thymus weight. Reduced serum A/G ratio, total cholesterol and alkaline phosphatase activity were restored or increased by ginseng p-ether fraction administration.

Nitric oxide is an important factor to regulate the biochemical reactions in the body such as expansion of blood vessel, neural conduction and antimicrobial activity. There are two forms of nitric oxide synthase and iNOS has attracted most attention because it is involved in the development of diabetes and cardiac disease condition. There are several regulatory sequences in the promoter region of iNOS gene. One of them is (CCTTT)n. It has been reported that the number of tandem repeat of (CCTTT)n varies from population to population. So, we analyzed (CCTTT)n polymorphism in Korean genome for the purpose of comparison. According to our present study Koreans are different from other Asians reported previously because $(CCTTT)_{10}$ is the highest incidence as opposed to $(CCTTT)_{12}$ for other countries. This study should facilitate the understanding of the expression of iNOS gene in different population.

Lectin is a cell-agglutinating and carbohydrate-binding protein present in many plants. The lectin of Canavalia ensiformis shoot with specific affinity for D-glucose was purified by affinity chromatography using Sephadex G-100, and some of its biochemical characterizations were studied. Lectin was purified 8.87-fold and exhibited final specific activity of 225.74 units/mg protein with a $2.3\%$ yield. SDS-PAGE analysis demonstrated that the purified shoot lectin exists as a tetramer of 102 kD, composed of two subunits with molecular weight of 29 and 22 kD. The purified lectin was observed to agglutinate rabbit blood cell. The optimal temperature for the activity of this lectin was $40^{\circ}C$, and this lectin was relatively stable to heat with the highest activity at $50{\~}60^{\circ}C$. The maximal activity was observed at pH 7.2.
