  • For this experiment frist the fermented Soybean Meju was prepared by domestic ordinary method of Korean and concentrated Meju suspensoidal extract was made for toxicological test sample on mice and rat. Even the oral dose of 10g extract per kg of mice had not any acute toxicity. So the median lethal dose(LOD50) is lilely to be much greatr or not to be. In comparison of the average weight gain rate for 4 weeks the control and test groups of 0.308g Ex/rat kg and 9.24g Ex/rat kg daily were the much the same as about 19% but 3.08g Ex/rat kg group waas exceptionally 2.7% higher than control For this period all test groups did not show any abnormality in appearance and anatomic findings. In serum GPT GOT alkaline phosphatase and blood urea nitrogen value there were no difference significantly between control and the test groups of 0.308g/rat kg and 3.08g/rat kg but 9.24g/rat kg group was some what higher than control. Especially in cholesterol alkaline phosphatase and blood urea nitrogen value 9.24g/rat kg group or 28days had 100mg/이 37.5u 32mg/이 respectively which were increased significantly. The pathological findings of all test groups especially 9.24g/kg group did not showed any characterized sign of acute or subacute liver damage or intestine lesion. So it is supposed that there is not any tocixants originated from some molds in fermented Korean domestic Meju which is prepared traditionally in winter.

  • Purpose: This study compared the effect of two oral care agents on preventing stomatitis and discomfort for acute leukemic patients. Methods: A total of forty patients was enrolled and randomly assigned to sodium bicarbonate or chlorhexidine group. WHO oral toxicity scale was used for measuring stomatitis and Beck's subjective oral discomfort scale for evaluating oral comfort. Data was collected from August 2009 to February 2010. The data was analyzed using Chi-square test, Fisher's exact test, and Mann-Whitney test. Results: Data analyzed was thirty five one. The incidence of stomatitis was 47.4%, 68.8% in sodium bicarbonate and chlohexidine group respectively. The onset of stomatitis was about the 10th and 9th day after chemotherapy initiation, and the duration was 8.0 and 8.67 day respectively. The severity of stomatitis was highest on the 21st day after chemotherapy initiation. There were no statistical differences in the status of stomatitis and the levels of oral comfort during treatment periods. Conclusion: Nurses should routinely assess oral cavity and encourage patients to do oral care actively from second to third week after chemotherapy initiation. Also sodium bicarbonate agent can be recommended to for preventing stomatitis.

  • To the rabbit and guinea pig, tartrazine was administered, either parenterally through venous or peritoneal injection or orally, with the amount of 7.5-50 mg/kg body weight in case of rabbit and 1,000-2,000mg per animal in case of guinea pig, in order to observe acute toxic effect of the dye in the animals. Blood serum was analyzed chemically and all the internal organs were microscopically observed for this purpose. The results point to the fact that severe hemorrhagic and congestive findings in most of the organs can be induced by the amount of the dye utilized, and particularly liver damage could be resulted.

  • Plant growth regulators are the chemicals that are found in plants and produced synthetically. In agricultural applications, plant hormones are used in minor quantities for fixing the problems. In our research, we studied the effects of 2,4 diclorophenoxyacetic acid (2,4D), which is an auxin used in agricultural applications. Auxins are the group that are used most popularly in plant growth regulators. In our study, different doses of 2,4 diclorophenoxyacetic acid are given to zebrafish, and ovarium tissues are observed histomorphologically. We generated one control and three experiment groups from the stock solution. The experiment was carried out in 20 liter capacity complete glass aquarium at $24{\pm}1^{\circ}C$ water temperature. After five days of application, fishes were dissected. Histomorphological changes of the ovarium were investigated under a light microscope. A decrease in the number of oocytes in zebrafish ovarium was observed when compared with the control group. Many deformed and underdeveloped oocytes were detected. An increase in the number of atretic oocytes was observed. It was deduced that acute doses of 2,4 diclorophenoxyacetic acid decelerates oogenesis in fishes.

  • Background: Azithromycin has broad spectrum and is effective to treat several bacterial respiratory tract infection. It is also relatively safe and tolerable to pediatric patient. Careful use of azithromycin is also required for the prescribers because it could cause cardiovascular toxicity (QTc prolongation) and ototoxicity. There has been no study on duration of azithromycin use in pediatric patients in Korea. Methods: The outpatient sample data on the azithromycin prescription was obtained from Korean health insurance review and assessment service. The characteristics of azithromycin prescription were analyzed with two different years (2011 and 2014). Results: Total 4,215 cases were analyzed. The azithromycin was prescribed the most frequently in the children (73.2% in 2011 and 62.5% in 2014) and for the condition of bronchopneumonia (28.7% in 2011 and 21.7% in 2014) in both years. The duration of prescribed for azithromycin has significantly different between 2011 and 2014. In 2014, 94.3% of prescription were indicated less than 5 days, but 86.6% were in 2011. Acute bronchiolitis and bronchopneumonia prescriptions more longer duration of treatment compared with acute bronchitis and others. Conclusion: The pattern of prescribing azithromycin has been changed for the treatment of several infectious diseases in pediatric patients. The rate of appropriate duration of azithromycin treatment has increased.

  • Multiple sclerosis is a degenerative disease prevalent in northern climates, and its cause is unknown. The histopathological lesion in multiple sclerosis is the sclerotic "plague", a discrete focus of myelin loss with maintenance of axon segments and glial proliferation. The plaques may be seen in widely different brain and spinal tissues. The common causes of low back pain are psychosomatic disorder, myofascial pain dysfunction syndrome and herniation of nucleus pulposus. Local anesthetics cross the blood-brain barrier and the signs of CNS toxicity appear at a level between 4.5 and $7.0\;{\mu}g/ml$. This is a case report of acute back pain care after mandibular block anesthesia for the surgical extraction of mandibular root rests in an old aged woman with multiple sclerosis.

  • Carbon monoxide (CO) intoxication is a leading cause of severe neuropsychological impairments. Peripheral nerve injury has rarely been reported. Following are brief statements describing the motor peripheral neuropathy involved bilateral lower extremities of a patient who recovered following acute carbon monoxide poisoning. After inhalation of smoke from a fire, a 60-year-old woman experienced bilateral leg weakness without edema or injury. Neurological examination showed diplegia and deep tendon areflexia in lower limbs. There was no sensory deficit in lower extremities, and no cognitive disturbances were detected. Creatine kinase was normal. Electroneuromyogram patterns were compatible with the diagnosis of bilateral axonal injury. Clinical course after normobaric oxygen and rehabilitation therapy was marked by complete recovery of neurological disorders. Peripheral neuropathy is an unusual complication of CO intoxication. Motor peripheral neuropathy involvement of bilateral lower extremities is exceptional. Various mechanisms have been implicated, including nerve compression secondary to rhabdomyolysis, nerve ischemia due to hypoxia, and direct nerve toxicity of carbon monoxide. Prognosis is commonly excellent without sequelae. Emergency physicians should understand the possible-neurologic presentations of CO intoxication and make a proper decision regarding treatment.

  • The purpose of the present study was to evaluate the possibility of application of pediatric hemodialysis system to dogs weighing less than 6 kg. Six healthy dogs (B .W, 3-6 kg) were used_ Experimental end-stage renal failure was induced by bilateral nephrectomy or bilateral ligation of ure-ters. Hemodialysis was performed when blood urea nitrogen (BUN) value increased over 90 mg/dl and every other day thereafter. Daily investigated parameters included clinical clinical signs such as vomiting, fecal appearance and activity and laboratory data such as PCV, WBC, RBC, BUN, creatinine, Ca, P, $Na^+ Cl^-and K^+$During hemodialysis treatment, BUN and creatinine values were measured hourly. Severe vomiting and inappetence were shown 2 days after infliction of kidney disorder and melena and mucous faces were observed 3 days. The signs were not corrected by hemodialysis treatment. Avel- age hemodialysis treatment time was $5.5 {\times} 0.7$,/TEX> hours until BUN value decreased to normal range. Abnor- mal hematological and electrolytes values were reduced within normal levels after hemodialysis treatments. The complications oft hemodialysis included vomiting, nausea, obstruction of intravascular catheter, tremor, seizure, temporary visual loss and continued decrease in PCV It is suggested that pediatric hemedialysis system can be applied to acute renal failure and acute toxicity. Further works on improvements in maintaining patency of catheter and in managing the complications of hemo- dialysis should be conducted.
