We evaluated the efficacy of the liquid form of enrofloxacin against poultry respiratory and digestive infections, the major problems in the poultry industry, from diverse diagnosis viewpoints. Results obtained through this study were as follows: 1. The liquid form of enrofloxacin showed good acceptability to poultry owing to no abhorrence to the drug by chickens, which indicated its suitability for mixing in drinking water. 2. The application of the enrofloxacin formulation improved the productivity of the chicken farm to a great extent by lowering the death toll of chicken raised in the farm. 3. The use of the drug shortened the days to the market, and increased the body weight at the time of marketing. 4. Preventive and therapeutic effects of the liquid enrofloxacin were observed higher than ampicillin, a major antibiotic used in poultry farming. From above results, the liquid form of enrofloxacin would find its use for the prevention and treatment of digestive and respiratory infections, let alone the growth promotion and feed efficiency, especially in the chicken farming practice.

In this study the antimicrobial spectrum and sensitivity of a liquid formulation of enrofloxacin against the major six pathogenic bacteria isolated from the diseased poultry in Korea were evaluated in comparison with ciprfloxacin (CFX), gentamicin (GM) and penicillin (PC). A liquid form of enrofloxacin, a test material and ciprofloxacin showed at least 83% antibacterial activity against all of six test pathogenic microorganisms at the fixed concentration of 10 ㎍/㎖. Gentamicin and penicillin revealed much lower antibacterial activity at the same condition. We evaluated the liquid form of enrofloxacin as having widespread antibacterial spectrum against poultry infections. The liquid form of enrofloxacin showed potent antibacterial activity, with the MIC range being 0.12∼2 ㎍/㎖ against Gram positives, 0.06∼2 ㎍/㎖ against Gram negatives and 0.5∼2 ㎍/㎖ against Mycoplasma spp. These values were equivalent to or somewhat higher than those of ciprofloxacin, but much lower than those of gentamicn and penicillin. This new liquid form of enrofloxacin would find its way in application of mixing with drinking water for the prevention and treatment of diverse infections in chickens.

Dermatomyositis is an autoimmune connective tissue disorder characterized by symmetrical proximal muscle weakness due to chronic inflammation and degeneration of skeletal muscle. Cancer occurs in patients with dermatomyositis with a frequency estimated between 15-20%. The common sites of malignancy are stomach, breast, ovary, lung and etc. The cases that have been reported so far are dermatomyositis associated with lymphoproliferative disorder and cancer of colon, liver, pancrease, pharynx, uterine cervix, testis, kidney. But dermatomyositis associated with thyroid cancer has not been reported in Korea. We, the authors, experienced a case of dermatomyositis associated with the thyroid cancer and as such we are reporting the case with literature reviews.

Background: The purpose of this article was to present a valid and reliable theoretical framework and method for the development of an integrated medical service model for the four major diseases. Methods: Methodologies for each process were presented based on three theoretical frameworks. The three theories were the double diamond process model, the Donabedian model, and the International Classification of Functioning, Disability, and Health model. Based on this, in the process of problem finding, a literature review, service user questionnaire, and interview methods were applied. For problem definition and solution, expert focus group interview and expert Delphi methods were applied. The subjects of the study were mainly selected from experts for each disease and users of medical services. For literature review, systematic literature review and subject range literature review were conducted, and for analysis, a meta-analysis was carried out. In the case of focus group interview and Delphi, the validity and reliability of domain derivation and sub-items were analyzed by applying the qualitative analysis method. Results: To develop an integrative medical service model, a theoretical framework and a systematic methodology were needed, and case studies were performed to prove its validity and reliability. This showed that the development of a medical service model needs to follow a scientific procedure. Conclusions: By introducing methodological approaches and procedures for the development of an integrated medical service model for the four major diseases, the researchers provided basic information on model development.

Objectives: This study was conducted to examine the relationship between crude oil exposure and physical symptoms among residents participating in clean-up work associated with the Hebei Spirit oil spill, 2007 in Korea. Methods: A total of 288 residents responded to a questionnaire regarding subjective physical symptoms, sociodemographic characteristics and clean-up activities that occurred between two and eight weeks after the accident. Additionally, the urine of 154 of the respondents was analyzed for metabolites of volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) and heavy metals. To compare the urinary levels of exposure biomarkers, the urine of 39 inland residents who were not directly exposed to the oil spill were analyzed. Results: Residents exposed to oil remnants through clean-up work showed associations between physical symptoms and the exposure levels defined in various ways, including days of work, degree of skin contamination, and levels of some urinary exposure biomarkers of VOCs, metabolites and metals, although no major abnormalities in urinary exposure biomarkers were observed. Conclusions: This study provides evidence of a relationship between crude oil exposure and acute human health effects and suggests the need for follow-up to evaluate the exposure status and long-term health effects of clean-up participants.

For many years. dental amalgam was considered to be a clinically acceptable benign material in the environment in which it was placed. However dental amalgam must contain mercury to provide the initial plasticity required for inserting the amalgam into cavity preparation and small amount of mercury can be released from dental amalgam. In recent studies, many investigators reported that dental amalgam could evoke the toxic effects in various tissues. These toxic effects of amalgam were due to its corrosion products or mercury and were related to the amount of mercury. This study was conducted to compare the amount of mercury released from various amalgam implants in vivo. Employing the commercially available domestic and foreign lathe cut alloys and mercury with optimal mercury/alloy ratio recommended by manufacturer, dental amalgam discs were prepared by packing freshly triturated amalgam into a cylinderical stainless steel mold (internal diam. 5mm) with pressure of 14 MPa. Then prepared amalgam discs were implanted in subcutaneous tissue at subscapular region of rats while porcelain discs were implanted as control. After 1, 3, 7, 14 and 28 days after implantation, mercury content of blood and kidney in each group was measured by flameless atomic absorption spectroscopy. The results were as followings; 1. Mercury content of blood and kidney was increased after dental amalgam implantation and the greater proportions of mercury, released from amalgam implants, were recovered in 1 day after implantation. 2. Concerned with the blood content of mercury, domestic amalgam implants were tend to produce more rapid increase and declination than the foreign products. 3. The amount of mercury released from domestic and foreign products, recovered from kidney, were not different significantly.
