  • The object of this study was to evaluate the single dose toxicity of Yukmijihwangtanggamibang (YMJHTGMB), a polyherbal formula have been traditionally used as prevention or treatment agent for various lung diseases including chronic obstructive pulmonary disease (COPD), in male and female mice. Aqueous extracts of YMJHTGMB (Yield = 16.33%) wasadministered to female and male ICR mice as an oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration (KFDA) Guidelines. Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation during 14 days after dosing, upon necropsy; organ weight and histopathology of 12 principle organs were examined. As results, we could not find any mortality, clinical signs, and changesin the body and organ weight except for soft feces restricted to YMJHTGMB 2,000 mg/kg treated two male mice (2/5; 40%) at 1 day after administration. In addition, no YMJHTGMB-treatment related abnormal gross findings and changes in histopathology of principle organs were detected except for some sporadic accidental findings. The results obtained in this study suggest that the 50% lethal dose and approximate lethal dose of YMJHTGMB aqueous extracts in both female and male mice were considered as over 2,000 mg/kg, the limited highest dosage recommended by KFDA Guidelines.

  • The acute toxicity of the combined vaccine (KGCC-95VI) for the prophylaxis against Japanese encephalitis and Hantaan virus infection. recently developed by Korea Green Cross Corporation, was investigated. KGCC-95VI was administered to the Balb /c mice in two routes, orally and subcutaneously, and into the New Zealand White rabbits subcutaneously. $LD_{50}$ was not accessible as there were no deaths in the group treated even at a dose 800 times the expected clinical dose in both animal species. Between the treated and control groups there were no statistically significant differences in body weight changes and clinical signs during the 14-day observation period, and no pathological gross findings. Accordingly KGCC-95VI is considered not to have the acute toxicity in mice and rabbits.

  • The object of this study was to evaluate the single dose toxicity of Kong-Jin-Dan (KJD), a polyherbal formula in male and female mice. KJD was administered to female and male ICR mice as an oral dose of 2000, 1000 and 500 mg/kg (body wt.) according to the recommendation of KFDA Guidelines. Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation during 14 days after dosing, upon necropsy, organ weight and histopathology of 12 principle organs were examined. As results, we could not find any mortality, clinical signs, and changes in the body and organ weight except for increases of lymphoid organ weights in KJD-dosing groups. These increases of lymphoid organ weights considered that related to the immune modulate effect of KJD not toxicological signs. In addition, no KJD-treatment related abnormal gross findings and changes in histopathology of principle organs were detected except for some sporadic accidental findings. The results obtained in this study suggest that the KJD does not cause any toxicological signs. The $LD_{50}$ and approximate LD of KJD extracts in both female and male mice were considered as over 2000 mg/kg.

  • High contrast and high resolution are the most important factors for examining mammography images. Despite of the inconveniences of screen-film, most clinics still prefer them to computed radiography(CR) and direct radiography(DR). The reading of screen-film mammography images is influenced by the brightness from the X-ray illuminator, the exam room and incoming light from outside sources. Therefore, a comparative analysis on the results of mammo phantom images would be variated by the changes in the reading environment. There was no influence on reading results from the examiners close distance eyesight(p > 0.05); however, reading of micro lesions improved with greater darkness in the X-ray film reading room and the brightness of the X-ray illuminator(p < 0.05). Also, observation of fiber and mass images were maximized at a distance of 50 cm from the reader. Now, it is possible to observe these small classification groups using a magnifying glass without being physically close to the image. For the image of mammography, obtaining high quality images is important but in order to get an accurate clinical lesions of the reading also needs to be considered the optimal environmental factors.

  • Patients with febrile illness and skin rashes need full and immediate attention. In general, these diseases show mild manifestations and good prognosis. However, causalities of some diseases with fever and rash may be life threatening or trivial. So, the differential diagnosis for those patients is extensive. A through history, a careful physical examination and close observation of clinical progress are very helpful and essential to confirming the diagnosis. Histories of recent travel, drug or specific food ingestion, exposure to human or an animal source of infection may be useful to discover the cause. Although laboratory tests can be useful in making the diagnosis, laboratory results usually are not available immediately. Knowledge and experiences of such diseases may be helpful to reduce the differential diagnosis to a few major possibilities. Rashes can be categorized as petechial, maculopapular, vesicular, urticarial and erythematous. Potential causes include infectious pathogens such as virus, bacteria, rickettsiae, spirohetes, connective tissue diseases, allergic diseases and heamto-oncologic diseases. Because the severity of these diseases can vary mild to life threatening, physicians must perform prompt management decisions regarding empirical therapies. In this article, the differential etiological diagnosis of each type rash is reviewed and discussed, and with emphasis on intensive care of life threatening febrile diseases with rashes that are seen in our country.
