Traditionally, the Rhododendron species has been used in gastrointestinal disorder or hypertension. Grayanotoxin exists in honey, flowers, pollen, and the nectar of the Rhododendron species. We experienced 3 cases of Grayanotoxin intoxication. The symptoms of intoxication were nausea, vomiting, hypotension, bradycardia, diplopia, dizziness, and chest discomfort. Generally, the treatment for Grayanotoxin intoxication is fluid resuscitation and injection of atropine sulfate. The patients who were intoxicated with Grayanotoxin were discharged without complication after supportive care.

PURPOSE: This study was to explore subjectivity on childbearing in high school students. METHODS: A Q-methodology which provides a method of analyzing the subjectivity of each type was used. Forty-three high school students classified 40 selected Q-statements into 9 points standard. The obtained data were analyzed by using the pc-QUANL program. RESULTS: High school students' subjectivity on childbearing were analyzed into two types: Type 1 turned out to be 'FOLS (family oriented life style)' and Type 2 'CINK (couple important no kid)'. CONCLUSION: In order to resolve such problems as low birth rate and the advanced age of the population, effective youth and adult programs, policy and institution are required. The current demographic, economic and other factors such as personal values and policies may lower birth rate. In particular, youths' need for children and birth rate tend to be lower. There are positive and negative patterns in high school students' subjectivity on childbearing. Thus, national and social efforts are needed to change negative factors into positive ones. In order to maintain positive subjectivity on childbearing in high school students, it is necessary to apply family-centered educational programs and to implement birth-friendly and realistic programs for promoting child birth.

Benzoylureas are chemical compounds best known for their use as insecticides. Diflubenzuron is one of the more commonly used benzoylurea pesticides. Others include chlorfluazuron, flufenoxuron, hexaflumuron, and triflumuron. They act as insect growth regulators by inhibiting synthesis of chitin in the body of the insect. They have low toxicity in mammals because mammals have no chitin. Chlorfluazuron insecticides, which are mixed with solvent naphatha, are commonly used. Thus we assume that in the presented case mental change outcome of poisoning was connected with toxic effects of solvent naphtha rather than with chlorfluazuron action. Components of solvent naphtha, particularly trimethylbenzenes, exert strong irritant action on the gastric mucosa and are very well absorbed from the gastrointestinal tract. We report on a 67-year-old man with stuporous mentality after intentional ingestion of approximately 200 ml of liquid chlorfluazuron in a suicide attempt. He was discharged after conservative treatments including gastric irrigation, charcoal, mechanical ventilation, hydration, and antibiotics for aspiration pneumonia without complications.

A total of 631 species of spiders have been reported in Korea. However, there are no spiders with noxious venom such as Latrodectus sp. Because of this, to date, no serious medical problems due to spider bites have been reported in Korea, and only two cases of spider bite were officially reported. However, as the number of earning spiders from other countries is increased, the number of cases of spider bite has also shown a recent increase. A 17-year-old man presented with numbness of both extremities after being bitten by a spider which he had as a pet. The spider is called an Indian ornamental tree spider (Poecilotheria regalis sp.), one kind of tarantula species. Herein, we report on a case of a spider bite by a tarantula.

Congenital laryngeal cleft is a rare anomaly, which can cause serious problems of airway and repeated aspiration pneumonia. It is due m failure of fusion of the posterior cricoid cartilage lamina. Dysphagia with aspiration of food is commonly seen w1h resultant bouts of pneumonia. Detection of an unsuspected minor cleft may be difficult, but the pediatrician should suspect the possibility of deft from the clinical features. This paper includes. a detailed case report of one patient with congenital laryngeal cleft and the review of literatures.

BACKGROUND: Macrophage migration inhibitory factor (MIF) is a unique protein, participating in inflammation, immune response, and cell growth. Previous reports showed that MIF-polymorphisms are associated with an increased risk for various inflammatory diseases. OBJECTIVE: This study was designed to investigate the effect of MIF polymorphisms on Behcet's disease (BD). METHODS: A total of 362 patients with BD and 290 healthy controls were genotyped. We also performed RT-PCR analysis, ELISA, and immunohistochemical stain for MIF. RESULTS: We could not find statistically significant differences in the genotype frequencies of the MIF-794[CATT]5-8 repeat polymorphism or MIF-173 G>C polymorphism between BD patients and controls. Immunohistochemical analysis showed that MIF protein was diffusely distributed throughout epidermis and subcutaneous fat tissue from the skin lesions of patients with BD and erythema nodosum. CONCLUSION: Contrary to earlier reports, serum MIF levels were decreased in patients with BD, and the prescence of polymorphisms in the MIF promoter region was not associated with disease susceptibility. Nevertheless, MIF may play a role in cutaneous inflammation in BD.

The aim of this study is to evaluate the reasonableness of the medical fee on oral and maxillofacial surgery field according to surgeon's opinions and actual conditions. The medical fee has significant influence on hospital income, the supply and distribution of medical manpower, quality and facilities of medical services. Questionnaire survey was sent to 86 oral and maxillofacial surgeons who worked more than 3 years in general hospital. Among them, 25 doctors replied the 109 answers survey and the average of treatment time and physician work relative value on each category was calculated. And the health insurance cost (that has been applied since 2003) was compared with the questionnaire results. And finally we investigated items that health insurance system did not include in oral and maxillofacial field but actually performed in oral and maxillofacial surgery clinic. The result was that the medical fee did not properly reflect physician work relative value of actual treatments. In case of complicated extraction, work relative value needed 3.5 times enhancement of present value. For simple impacted tooth extraction 1.8 times, for impacted tooth extraction including odontomy 1.7 times, and for fully impacted tooth more than 2/3 of it located into the alveolar bone, 1.8 times enhancement needed. In respect of the present physician work relative value, hemimandibulectomy with neck lymph node dissection for the malignancy is appropriated as 3.3 times of open reduction and internal fixation for the mandibular fracture, but the questionnaire result showed 25 times discrepancy. In conclusion, this research shows the need for intervention that health insurance included items and legal relative medical value must act in union with treatment in clinic to reduce the imbalance between them.

Subclavian artery(SCA) injuries are rare, accounting for only 1 to 2% of all acute vascular injuries. The majority of SCA injuries are occured by motor vehicle accident and by penetrating trauma, only 1 to 5% of all subclavian artery injuries occurred by blunt mechanisms. The incidence of brachial plexus injury is also rare and 60% of brachial plexus injuries induced by blunt injury is occurred by motor vehicle accident. Aggressive diagnostic work-up is recommended for the patients with high suspicious index and repair is essential for the successful management of these rare vascular injuries. We report the experience of one case of combined subclavian artery and brachial plexus injuries due to blunt trauma.

Hypernatremia is a common electrolyte disorder in children and elderly people and has high short-term mortality. However, no high-quality studies have examined the correction rate of hypernatremia and the amount of fluid required for correction. Therefore, in this study, we will compare the efficacy and safety of rapid intermittent bolus (RIB) and slow continuous infusion (SCI) of electrolyte-free solution in hypernatremia treatment. Methods: This is a prospective, investigator-initiated, multicenter, open-label, randomized controlled study with two experimental groups. A total of 166 participants with severe hypernatremia will be enrolled and divided into two randomized groups; both the RIB and SCI groups will be managed with electrolyte-free water. We plan to infuse the same amount of fluid to both groups, for 1 hour in the RIB group and continuously in the SCI group. The primary outcome is a rapid decrease in serum sodium levels within 24 hours. The secondary outcomes will further compare the efficacy and safety of the two treatment protocols. Conclusion: This is the first randomized controlled trial to evaluate the efficacy and safety of RIB correction compared with SCI in adult patients with severe hypernatremia.

BACKGROUND: Proteinase-activated receptor 2 (PAR2) is cleaved, and it is activated by trypsin or mast cell tryptase. PAR2 plays an important role in inflammation. The aim of this study is to examine the potential of PAR2 agonists to modulate TNF-alpha secretion from the human astrocytoma cell line CCF-STTG1. METHODS: PAR2 expression in CCF-STTG1 was examined using reverse transcriptase polymerase chain reaction and immunocytochemistry. The potential of PAR2 agonists to modulate TNF-alpha secretion from CCF-STTG1 was examined by enzyme-linked immunosorbent assays. RESULTS: CCF-STTG1 expresses PAR2. PAR2 agonists such as trypsin, mast cell tryptase, and activating peptide SLIGKV-NH2 (corresponding to the PAR2 tethered ligand) directly signal CCF-STTG1 to induce the secretion of TNF-alpha but not in the case of the soybean trypsin inhibitor (SBTI) or VKGILS-NH2 (control peptide). Furthermore, the secretion of TNF-alpha was significantly reduced in CCF-STTG1 cells pre-treated with either 50 microM PD98059 (mitogen-activated protein/extracellular signal-regulated kinase kinase (MEK) inhibitor) or 1 microM SB203580 (p38 MAPK inhibitor) 30 min before trypsin stimulation. CONCLUSIONS: These results show that trypsin may induce TNF-alpha secretion through the activation of MEK and p38 MAPK via PAR2 in astrocytoma cell line CCF-STTG1.
