This study was conducted to detect the toxoplasma-specific DNA in peripheral blood collected from cats experimentally infected with Toxoplasma gondii (RH strain) and from domiciled cats by B1 gene-base polymerise chain reaction(PCR). The sensitivity of oligonucleotide primer, T-1 & T-2, designed from toxoplasma B1 gene amplification method was compared with parasite detection by mouse inoculation(MI). And also, latex agglutination test(LAT) and indirect fluorescent antibody test(IFAT) were conducted to detect the fluctuation of serum antibodies compared with the detection of toxoplasma by PCR and MI. Toxoplasma B1 gene PCR was shown consistently high sensitivity and the results obtained by PCR agreed completely with those from MI. All blood samples collected before infection with T gondii gave negative results by PCR and MI. Also, toxoplasma Bl gene PCR was not cross reaction with Neospora caninum DNA and normal cat leucocyte as controls. The toxoplasma-specific DNA was detected by PCR in blood of 5 cats experimentally infected with T gondii 6 days after infection and the detection of this specific-DNA was long lasted in blood for 64 days after infection. The detection of toxoplasma-specific DNA by PCR could be identified as few as 10 tachyzoites and the isolation of T gondii by MI could be isolated as few as 1 tachyzoite from tenfold serial dilution of T gondii with normal cat blood, respectively. In healthy domiciled cats, the toxoplasma-specific DNA and the parasite were detected and isolated in blood from 3 of 56(5.3%) cats by both PCR and MI, respectively. In the results of antibody test from the total 56 heads of healthy domiciled cats, the positive rates are 15(26.7%) by LAT and 19(33.9%) by IFAT. These results suggest that PCR detection of toxoplasma can be applied as a sensitive and specific diagnostic and research tool.

The purpose of this study is to determine the effect of oral vitamin C supplements on blood sugar and serum lipid level(total cholesterol, triglyceride, high density lipoprotein, low density lipoprotein) in non-insulin independent diabetes mellitus. The study design was a non equivalent control group pre-test post-test design. Data for the study were collected from June 24 to August 31, 2001. The ninty-five research subject were assigned to experimental group(51) and control group(44). Vitamin C(3g/day) was given to 51 subjects for 4 weeks. Following a 12h overnight fasting, blood sample was obstaind at baseline and at the end of 4week - supplementation. Blood samples were taken for plasma vitamin C concentration, fasting blood sugar, HbA1c and serum lipid level. The pre-equivalent test was used by Chi-squre, t-test and two group's pre and post experimental differences were analyzed by t-tset to compare with each other. The results of this study were as follows ; 1. The difference between the two groups in plasma vitamin C concentration was significant(t=-12.950, p=.000). 2. The difference between the two groups in fasting blood sugar was significant(t=5.293, p=.000). 3. The difference between the two groups in HbA1c was not significant(t=1.758, p=.082). 4. The difference between the two groups in total cholesterol, HDL, LDL was significant(t=3.786, p=.000 ; t=-5.515, p=.000 ; t= 4.169, p = .000). These results suggest that megadose vitamin C supplementation be effective in lowering fasting blood sugar, serum lipids and increasing plasma vitamin C. Thus dietary measures to increase plasma vitamin C may be on important health strategy for reducing the compliance of diabetic patients.

This study was designed to provide the base of nursing intervention that could help apheresis blood-donors to promote self-efficacy effectively by analyzing critical factors that influence on this. The subjects recruited for the research were 468 persons who participated in platelet donation at a university hospital apheresis unit in Seoul. The data for this study were collected between May and June, 2002 using questionnaires. Data were analyzed by t-test, ANOVA, Scheffe test, and stepwise multiple regression. The results were as follows. 1. The mean self-efficacy score on the questions related to blood donation was $32.9\pm5.1$, indicating that blood donors have above the mean level of self-efficacy related to blood donation. 2. The self-efficacy score was significantly higher for the group of persons who have more than 5 times of experiences in blood donation than others who have only one experience. 3. The critical factors that influence self-efficacy related to donation were the marital status, educational level. and previous experiences of whole blood donation, while the critical factor that influence on general self-efficacy was previous experiences of whole blood donation. Therefore, it is necessary to establish more effective and organized nursing intervention strategies that can promote the self-efficacy of apheresis blood-donors.

This study was conducted to figure out the differences of the BMI, blood lipids, blood pressure and nutrient intakes by serum insulin concentration among adults in Korea. Ninety-three subjects(male : n=37, female : n=56) participated in this study. The subjects were grouped by serum insulin concentrations into two groups-hyperinsulinemia group(n=17) and normoinsulinemia group(n=76). Anthropometric measurements, blood lipid profiles, blood pressure, oral glucose tolerance test, and daily nutrient intakes were analyzed. And serum glucose and insulin secretion pattern as shown through and oral glucose tolerance test were performed. BMI (p<0.05) and WHR(p<0.01) were significantly higher in hyperinsulinemic group than in normoinsulinemia group. There was no differences in fasting blood glucose level between groups, but total glucose area (p<0.001) and insulin glucose resistance(p<0.001) were significantly higher in hyperinsulinemia group than in normoinsulinemia higher in hyperinsulinemia group, but HDL-cholesterol(p<0.05), and systolic blood pressure(p<0.05) were significantly higher in hyperinsulinemia group, but HDL-cholesterol(p<0.001) was significantly lower in hyperinsulinemia group. They showed significant differences in energy, carbohydrate, potassium, riboflavin, niacin and dietary fiber intakes(p<0.05), the intake of those nutrients were low in normoinsulinemia group. Further investigation is necessary to determine the effects of amounts and types of carbohydrate and dietary fiber on serum insulin concentrations.

Purpose: Glufosinate ammonium (GA; phosphinothricin) can induce neurological complications such as altered mental status, amnesia, and convulsions. This study was conducted to evaluate whether blood lipid profiles can help predict convulsions in patients with GA poisoning. Methods: This study was a retrospective review of data acquired at a tertiary academic university hospital from March 2014 to July 2016. Independent t-test, Mann-Whitney test and Analysis of covariance (ANCOVA) of demographic and laboratory findings of 50 patients with GA poisoning were performed to identify correlations of general characteristics and laboratory findings, including blood lipid profiles of GA-poisoned patients between with and without convulsions. Results: Convulsion as a GA complication showed a significant association with poison volume, age, white blood cell count, and creatine phosphokinase (CK), albumin, lactate dehydrogenase (LDH), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) content in blood according to an independent t-test and Mann-Whitney test. However, ANCOVA demonstrated significant association with LDL and triglyceride. Conclusion: Blood lipid profiles, especially serum LDL and triglyceride, were useful in predicting convulsions in patients with GA poisoning.

We executed this experiment to observe side effects of warfarin, the anticoagulant that is used for preventing thrombus in cardiovascular surgery for calves. The 6 calves(70-130 kg) were used in this experiment regardless of sexes. We administered warfarin at 0.07 mg/kg daily for 25 days. Blood was collected before warfarin administration, every five days for 30 days. PCV, RBC, WBC, fibrinogen, total protein and platelet as blood test, prothrombin time (PT) as blood coagulation test, and AST, SDH, total bilirubin, BUN and creatinine as serum biochemical tests were measured. As the result of the experiment, PT has been gradually increased after warfarin administration. It has been gradually increased and remains within the therapeutic range from the third day to the 28th day. PCV and RBC were decreased significantly from the value before the administration (p < 0.05). In the serum biochemical test, SDH shows significant increase comparing the value before the administration (p < 0.05). AST and total bilirubin were increased gradually from the value before the administration. Considering the result of the experiment, to give wafarin to prevent thrombus in cardiovascular surgery, we can get anticoagulation effect with minimal administration(0.07 mg/kg, PO) from the third day of the administration. However because of the decreased PCV and RBC, it may cause anemia. It may cause damage to liver based on the result of serum biochemical test.

According to increase of domestic blood components use, the quality control of blood components is necessary to support good products. The purpose of this study is used to provide the producing index of the good product as compared with the accuracy and validity for the distribution of the quality control data. The value of mean, standard deviation, 95% confidence interval and degree of normal distribution of data were calculated by univariate procedure, the value of monthly mean of each blood centers per items were compared by Analysis of Variance(ANOVA) test for the degree of distribution. When there was difference among the mean values, the Duncan's multiple range test was done to confirm the difference. Finally, methods for accessing accuracy and validity of the quality data was done by the Contingency table test. The quality data of five blood centers was showed to the normal distribution and it was in a acceptable range. For each blood centers, the monthly means of Hematocrit(Hct), Platelet(PLT) and pH were not significantly different except Hct of C center, PLT of B, D center and pH of A center. The quality data per items was graded according to quality to six level. As a result of the comparative analysis, the monthly means of Hct of C and E center was significantly different higher than that of D, B and A center. The monthly means of PLT of A center and pH of C center was significantly different higher than that of the others. In the accuracy and validity of the quality control data, C center for Hct, A center for PLT and C center for pH were better than the other. The C blood center was most satisfiable and stable in the quality control for blood component. If the quality control method used in C blood center is adopted in other blood centers, the prepared level of the blood component of the center will be improved partly.

Objectives: Orthognathic surgery is a surgical procedure performed by intraoral approach with established and safe techniques; however, excessive blood loss has been reported in rare cases. In response, investigative efforts to identify methods to reduce the amount of blood loss have been made. Among such methods, the administration of tranexamic acid was reported to reduce the amount of intraoperative blood loss. However, few studies to date have reported the effect of tranexamic acid in orthognathic surgery under hypotensive anesthesia. The present study aimed to investigate the effect of the administration of tranexamic acid on intraoperative blood loss in patients undergoing bimaxillary (maxillary and mandibular) orthognathic surgery under hypotensive anesthesia. Patients and Methods: A total of 156 patients (mean age, 27.0±10.8 years) who underwent bimaxillary orthognathic surgery under hypotensive anesthesia performed by the same surgeon between June 2013 and February 2022 were included in this study. The following data were collected from the medical records of each patient: background factors (age, sex, and body mass index), use of tranexamic acid, surgical procedures, previous medical history, duration of surgery, American Society of Anesthesiology physical status findings before surgery, intraoperative blood loss as a primary outcome, in-out balance, and blood test results. Descriptive statistics were calculated for statistical analysis, and a t-test and the chi-squared test were used for between-group comparisons. Group comparisons were performed after 1:1 propensity score matching to adjust for confounding factors. Statistical significance was set at P<0.05. Results: Comparison between the groups based on the use of tranexamic acid revealed a significant difference in operation time. Propensity score matching analysis revealed that intraoperative blood loss was significantly lower in the tranexamic acid group. Conclusion: The administration of tranexamic acid was effective in reducing intraoperative blood loss in patients undergoing bimaxillary orthognathic surgery under hypotensive anesthesia.
