  • As a preliminary step for production of large quantities of porcine leucocyte interferon(Por IFN-${\alha}$), various factors such as the sources of leucocytes, inducers and culture conditions were investigated. In addition, an assay system for the potency of porcine interferon was developed in a micro-system by using porcine kidney cell line, PK-15, and vesicular stomatitis virus. By the experiments, it was found that the porcine leucocyte interferon was synthesized more effectively in the leucocyte suspension with the higher viability and the lesser erythrocyte contamination. Regarding cell sources, the peripheral leucocytes produced a consistently higher unit of interferon than the spleen cells. When the efficiency of inducers was compared, the Sendai virus at the concentration of 125 HA unit/ml was found to be more effective for porcine leucocyte interferon production than the Newcastle disease virus. Average potency of 9 batches of the crude interferon measured by the established assay system was 1,200 unit/ml.

  • It is generally accepted that the delivery of health care is undergoing many changes specially those related to acute, contagious disease care and to the increase of chronic illnesses which can not be cured but are controlable. The health care practitioner can not be soley responsible for the control of their clients' care. Because the clients will play a vital role in controlling their illnesses, long term participation by both the health care provider and the client is necessary. Since most individuals with hypertension do not experience signs or symptoms, the disease is difficult to detect and even when diagnosed, clients do not comply well with their hypertension regimens. The noncompliant client is at increased risk for compliants involving the heart, brain, kidney and other organs. In an effort to explore methods of increasing patient participation in and adherence to treatment programs for hypertension, the researcher used health contracting to promote self care. The research questions are; 1) Will the health contracting increase compliance in health behavior and reduce the blood pressure\ulcorner 2) If clients comply with their regimens will this reduce their blood pressure\ulcorner The research design utilized in this study was a quasi-experimental design. A purposive sample, was abtained from two churches in the 1. area, consisting of 64 clients with hypertension. The data was collected from the middle of January to the 1st of September 1985. Randomization was only of the two church groups into experimental and control groups. Compliance with health behavior related to the hypertensive regimen, blood pressure and body weight were measured, compared and analyzed. In the experimental group measurements were made 6 times; one month before the education program after education program when health contracting was done and 4 more times once a month for 4 months. In the control group measurements were made 3 times; one month before the education program after the education program, and once 4 months later. There was no health contracting. The data were analyzed by t-test, Pearson correlation and ANOVA according to purpose of the study. The result of this study may be summarized as follows: The result related to the hypothesis on the effect of health contracting are as follows: H$_1$; “The hypothesis that the experimental group, with a health contractual agreement will demonstrate increased compliance levels for health behavior than the control group” was supported(t=-5.29, df=62, p=.000). H$_2$; “The hypothesis that the experimental group, with a health contractual agreement, will demonstrate a greater reduction in blood pressure than the control group” was supported (for systolic blood pressure t=2.72, df=62, p=.009, for diastolic blood pressure t=1.95, df=62, p=.050). H$_3$; The hypothesis that the greater the compliance of the client with health behavior the lower the client's blood pressure will be was partially supported (for systolic pressure r=-.2981, p=.008, for diastolic pressure r=-.1720, p=.087). From the examination of the results of this study it can be concluded that the interaction between the nurse and the client, contracting to define goals and reinforcing compliant behavior, leads to improved compliance with health care behaviors and thus to an increase in the effectiveness of nursing care. Further consideration need to be given to the inclusion of the concept of health contracting in primary nursing and to further research in this area.

  • The purpose of this study was to investigate the relationship of Dampness-phlegm to blood lipid level and second reason of hyperlipidemia in acute stroke patients by case-control study. This study was done over 348 patients hospitalized in the Oriental Medical Hospital of Daejeon University of November 2006 to July 2008. Patients had been interviewed by residents and medical specialists who studied standard operation procedures in Fundamental Study for Syndrome of Oriental Medicine for Stroke. Study subjects consisted of 86 patients who distributed to Dampness-phlegm by medical specialist and discriminating program as the case I group, 157 patients who distributed to Dampness-phlegm by medical specialist or discriminating program as the case II group and 191 patients who distributed to Non-Dampness-phlegm by medical specialist and discriminating program as the control group. For the purpose of obtaining suitable result we analyzed blood lipid level of each group by univariate and multivariate logistic analysis. Dampness-phlegm was not significant correlated with increasing of Total cholesterol, Triglyceride and decreasing of HDL cholesterol. Dampness-phlegm was significant correlated with increasing LDL cholesterol and the independent predictors of hyperlipoproteinemia by multivariate logistic analysis. Dampness-phlegm was not significant correlated with diabetes melitus, liver disease, kidney disease, obesity and abdominal obesity. In this study, we demonstrated new relationship between Dampness-phlegm and LDL cholesterol. Based on these results, it is suggested that Dampness-phlegm would be the independent predictors of hyperlipoproteinemia. And more prospective studies are to be done with more clinical data.

  • Recently, a new disease showing symptoms such as epidermal exfoliation and muscular necrosis occurred in cultured Korean catfish. Although the mortality of fishes was low but the economic damages owing to loss of commercial value were severe. The authors isolated the causative agent from diseased fish and observed pathological changes both in naturally and artificially infected fish. The causative bacteria was identified as Aeromonas veronii. Subsequently we observed the daily death and pathological symptoms of artificially infected fish with Aeromonas veronii. Symptoms of artificially infected fish were similar to those of naturally infected fish and all fish died within 7 days after infection. Histopathological changes on the naturally infected fish revealed severe congestion and necrotic degeneration in the liver, spleen and kidney. Some bacterial aggregates with inflammatory degeneration were observed in the heart, and congestion and fibrosis in the lamina propria of digestive tube were predominant. In artificially infected fish, skin erosion and necrotic degeneration of muscle tissue around injected region were particularly manifested. Degeneration of hepatocytes in liver and hyalic degeneration around ellipsoids in spleen were partially observed. However, there were no predominant signs in digestive tube in artificially infected fish.

  • This study was perfomed to investigate the effects of Chunghyul-plus(CHP) on oxidative damage and hyperlipidemia in db/db mouse. After treatment with CHP, safety in cytotoxicity, heavy metal toxicity, production of reactive oxygen species(ROS), nitric oxide (N0) and proinflammatory cytokine IL-Ib, TNF-a, IL-6 in RAW 264.7 cells. Serum total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, insulin, GLP-1, glucose, food intake, body weight, organ weight, AST, ALT, ALP, BUN, creatine and histologic change of liver and aorta were measured in db/db mouse after oral administration of CHP. CHP showed safety in cytotoxicity and toxicity of liver and kidney for logn time administration. CHP increased the DPPH and ABTS radical scavenging activity. CHP showed significant inhibitory effect on reactive oxygen species (ROS), and showed inhibitory effect on nitiric oxide(NO) compared to control group. CHP decreased cytokine IL-6 production significantly, and decreased IL-1β and TNF-α compared to control group. CHP decreased body and organ weitht, intake food, and glucose levels compared to control group. CHP decreased total cholesterol and triglyceride significantly, and decreased LDL-cholesterol levels and increased HDL-cholesterol levels compared to control group. CHP decreased atherogenic index and cardiac risk factor significantly. CHP increased serum insulin and GLP-1 compared to control group. In histologic examination, lipophagy in the liver and aorta decreased in CHP treated mice and the cell was regular and boundary of vessel wall was clear compared to control group. These results suggest that CHP is effective in antioxidation activity and treatment and prevention of hyperlipidemia, atherosclerosis, diabetes, ischemic heart disease, stroke and other cardiocerebrovascular disease.

  • Purpose Glomerular filtration rate (GFR) is an important index for evaluation of renal function, renal disease diagnosis and progress monitoring. Therefore, accurate measurement of GFR is clinically important. Among the factors that affect the GFR result, there have been many discussions on the methods such as the correction of the kidney depth, net syringe count, and the method of setting the ROI. However there has been no consideration of counting in the most basic factors like height and weight measurement. In this study, we investigate how height and weight changes affects the result of GFR and review the importance of standardized body measurements. Materials and Methods Fifty patients who underwent GFR test were randomly sampled and examined for changes in height and body weight within one month. From the normal patients without renal disease to the patients with severely decreased GFR, we applied the GFR formula of Gate with varying height and weight. Results: The result showed variation of the height at maximum three centimeters and six kilograms of weight. The first calculation of GFR was done with fixed height value and control variable as weight. Weight was incremented by one kilogram each time up to six kilograms. The GFR showed increased result with increasing weight. The result of GFR showed ten percent increase with six kilograms of weight increase. On the other hand, when height value was incremented by one centimeter up to three centimeters showed decreased GFR result with fixed weight value. Up to three centimeters of height increase showed two percent of decreased GFR with fixed weight. Conclusion This study showed varying GFR result when height and weight changes. Therefore it is clinically crucial not only to maintain and manage body measuring instrument but also to have a standardized measurement methods to derive accurate measured values and to achieve reproducibility.

  • Purpose: In acute acetaminophen poisoning, the administration of N-acetylcysteine (NAC) can effectively treat the main complications, such as kidney injury and liver failure. In the current situation, measurements of the acetaminophen concentration are not checked in the usual medical facilities. Therefore, this study examined the factors of determining the administration of NAC in addition to the stated amount of intake. Methods: The medical records of patients who visited Ajou University Hospital emergency center with acetaminophen poisoning from January 2015 to December 2019 were reviewed retrospectively. One hundred and seventy-nine patients were initially included. Among these patients, 82 patients were finally selected according to the inclusion criteria in the study. The inclusion criteria were as follows: patients who were 15 years of age or older; those whose ingested dose, ingested time, and body weight were clearly identified; and patients whose acetaminophen sampling time was within 24 hours. Patients were divided into two groups: NAC administered vs. non-NAC administered. The following variables were compared in these two groups: ingested dose, ingested dose per body weight, hospital arrival time after ingestion, suicide attempt history, psychiatric disease history, classification of toxic/non-toxic groups, duration of hospitalization, and laboratory results. Results: Univariate analysis revealed the ingested dose per body weight, hospital arrival time after ingestion, suicide attempt history, and psychiatric disease history to be the determining factors in administering NAC. Logistic regression analysis confirmed that the ingested dose per body weight was the only significant factor leading to an NAC treatment decision. (Odds ratio=1.039, 95% Confidential interval=1.009-1.070, p=0.009) Conclusion: The ingested dose per body weight was the only determining factor for administering NAC in patients with acute acetaminophen poisoning. On the other hand, additional criteria or indicators for the NAC administration decision will be necessary considering the inaccuracy of the ingested dose per body weight and the efficiency of NAC administration.

  • Continuous mortality in commercially cultured Japanese eel (Anguilla japonica), showing symptoms of dermal ulcerations and focal hemorrhages on the body, occurred on a private farm in November, 2019 in Korea. A series of mortality had been described in one local eel culture farm from November to December in 2019. From the three cases, three isolates of Vibrio spp. were recovered from the blood, ascitic fluid, and kidney of the dead fish, respectively. Based on the 16S rRNA sequence comparisons, the Vibrio isolates from the 1st and 3rd cases (strain named 1E1-2 and 3K1-2) were identified as V. fluvialis and the isolate from the 2nd case was identified as V. plantisponsor (strain named 2A3-1). Moreover, the 16S rRNA-based phylogenetic analysis revealed that strain 1E1-2 and 3K1-2 were most similar to V. fluvialis NBRC 103150T, and strain 2A3-1 was most similar to V. plantisponsor NBRC103148T. According to the results of the antibiotic resistance determination, V. fluvialis 1E1-2 showed intermediate resistance to tetracycline and chloramphenicol, and was resistant to trimethoprim-sulfamethoxazole. V. plantisponsor 2A3-1 showed intermediate resistance to ciprofloxacin and levofloxacin, and was resistant to trimethoprim-sulfamethoxazole. V. fluvialis 3K1-2 showed intermediate resistance to tetracycline, and was resistant to ampicillin and trimethoprim-sulfamethoxazole. These results have provided the evidences on the occurrence of antibiotic-resistant Vibrio infection in commercially cultured Japanese eels are present in Korea.

  • In this study, the effect of a synbiotic mixture of probiotics and 3% inulin on the growth, non-specific immune response, and mortality due to disease resistance of Paralichthys olivaceus was investigated. The results revealed that an 8-week diet of synbiotic-added feed, had no significant effect on the growth of P. olivaceus, Analysis of the hematological parameters revealed that there was a significant difference in the content of AST, total protein, and cholesterol among the groups, whereas there was no significant difference in the ALT and glucose contents. Further, there was no significant difference in the lysozyme activity of the synbiotic and control group after 8 weeks' feeding. In addition, when the symbiotic mixture was used rather than probiotics alone, the NBT activity of the synbiotic group increased compared to that of the control group. Moreover, when only probiotics were used, the cytokine expression in the spleen of the samples was significantly lower than that in the control group, whereas the expression was significantly higher in the spleen of the synbiotics group. However, there was no significant difference in the cytokine expression in the liver, intestine, and kidney of the three groups. Lastly, after injection for 2 weeks, the mortality rates of the control group towards Edwardsiella tarda, Streptococcus parauberis, and Streptococcus iniae were 95, 85 and 85%, respectively; those of the probiotics group were 85, 80, and 80%, respectively; and those of the synbiotics group were 80, 80, and 85%, respectively.
