Purpose: The triglyceride-to-high-density lipoprotein-cholesterol (TG/HDL-C) ratio is one of the main predictive indices for cardiovascular disease. This study was examined the relationship between TG/HDL-C ratio and metabolic syndrome (MetS) in male office workers. Methods: Secondary analysis was conducted to determine the risk between the TG/HDL-C ratio and MetS in male office workers. A total of 765 people underwent the 'regular workplace health checkups in 2014'. Among the subjects who were male and responded to the questionnaire and health lifestyle survey, 470 (61.4%) excluding those with missing and/or abnormal values were analyzed. The association between MetS, MetS components, and the TG/HDL-C ratio was examined by a Chi-square test, One-way ANOVA, Turkey post-hoc test and Logistic regression analysis. Results: The number of males with MetS was 70 (14.9%) and the number of MetS components increased with increasing TG/HDL-C ratio (p<.001). Logistic regression analysis with an adjustment for potential confounders revealed a 31.8 times higher odds ratio of the Quartile4 group for MetS than that of the Quartile1 group (p<.001). Conclusion: These results show that the likelihood of MetS, particularly the risk of MetS in the Quartile4, increases with increasing TG/HDL-C ratio.

In this study, we investigated the effects of obesity index on the risk factors of chronic diseases in obese children. The subjects were male and female children aged 9 to 12. The average obesity index was 147.7$\pm$13.8% in boys and 147.6$\pm$16.5% in girls. The average percentages of body fat was significantly higher in boys(33.9$\pm$5.7%) than in girls(30.7$\pm$4.4%). It was found that 26% of subjects had abnormal serum GOT and GPT values. Percentages of subjects at risk of cardiovascular disease(CVD) based on corresponding criteria of TG, T chol, HDL chol, and LDL chol were 28.6%, 28.6%, 45.5% and 42.7%, respectively. The risk of CVD was increased with the degree of obesity, which was not significant. The AI(atherogenic index) was higher in boys(4.6$\pm$2.3) than in girls(3.6$\pm$1.2). The serum T chol and LDL chol levels of subjects whose mother are in thirties were significantly higher than those of subjects whose mother are in fourties. The T chol levels of subjects who had mother with job were significantly higher compaired to those of subjects who had housewife mother. The results indicated the urgent need of nu tritional management for the obese children to prevent further devel opment of childhood obesity and hyperlipidemia. Based upon this study, devising method and media for the mother nutritional education as well as for the children nutritional education is required for better growth and health promotion of primary school children.

Mediastinal emphysema, also referred to as pneumomediastinum or Hamman's syndrome, is defined as the presence of air or gas within the fascial planes of the mediastinum. Superior extension of air into the cervicofacial subcutaneous space via communications between the mediastinum and cervical fascial planes or spaces occurs occasionally. The mediastinal air may originate from the respiratory tract, the intrathoracic airway, the lung parenchyma, or the gastrointestinal tract. The presence of air in the mediastinum may be spontaneous, iatrogenic or due to penetrating trauma. Pneumothorax is defined as the presence of air or gas within the pleural cavity. A pneumothorax can occur spontaneously. It can also occur as the result of a disease or injury to the lung or due to a puncture to the chest wall. Pneumomediastinum and pneumothorax is a rare complication of head and neck surgery. Nevertheless, when it occurs, it is usually considered to result from direct dissection by the air at the time of injury or of surgery. Most of the cases of pneumomediastinum and pneumothorax that have been described in the oral and maxillofacial surgery literature result from air dissecting down the fascial planes of the neck. The authors report a case with subcutaneous emphysema, pneumomediastinum and pneumothorax after orthognathic surgery.

The wide deep penetrating wound of maxillofacial region should be early closed under emergency general anesthesia for the prevention of complications of bleeding, infection, shock & residual scars. But, if the emergency general anesthesia wound be impossible because of pneumoconiosis, obstructive pulmonary disease & hypovolemic shock, early primary closure should be done under local anesthesia by use of much amount of the anesthetic solution. The maximum dose of dental lidocaine (2% lidocaine with 1 : 100,000 epinephrine) is reported to 7 mg/kg under 500 mg (13.8 ampules) in normal adult. But the maximum permissible dose of dental lidocaine can be changed owing to the general health, rapidity of injection, resorption, distribution & excretion of the drug. The blood level of overdose toxicity is above $4.0{\mu}g/ml$ in central nervous & cardiovascular system. The injection of dental lidocaine 1-4 ampules is attained to the blood level of $1{\mu}g/ml$ in normal healthy adult. The duration of anesthetic action in the dental 2% lidocaine hydrochloride with 1 : 100.000 epinephrine is 45 to 75 minutes and the period to elimination is about 2 to 4 hours. Therefore, authors selected the following anesthetic methods that the first injection of 6 ampules is applied into the deeper periosteal layer for anesthetic action during 1 hour, the second injection into the deeper muscle & fascial layer, the third injection into the superficial muscle and fascial layer, the fourth injection into the proximal skin & subcutaneous tissue and the fifth final injection into the distal skin & subcutaneous tissue. The total 26-28 ampules of dental lidocaine were injected into the wound as the regular time interval during 5-6 hours, but there were no systemic complications, such as, agitation, talkativeness, convulsion and specific change of vital signs and consciousness.

We present a case of osteoradionecrosis treated with leukocyte- and platelet-rich fibrin (LPRF) and surgery and followed up with clinical and tomographic investigations. A 65-year-old woman presented with pain in the posterior region of the right palate. Her medical history included cardiovascular disease and squamous cell carcinoma in the anterior region of the floor of the mouth that had been treated with intensity-modulated radiation therapy. Measurements of isodose curves showed a full dosage of 6,462.6 cGy in the anterior mandibular region, whereas that in the posterior region on the right side of the maxilla reached 5,708.1 cGy. Osteotomy was performed using rotary instruments, and debridement and placement of two LPRF membranes were also carried out. New gum tissue with no bone exposure was noted 14 days postoperatively. Tissue repair was complete, and the patient had no further complaints. During a 39-month follow-up period, the oral mucosa remained intact, and the patient was rehabilitated with a new upper denture. Since there is no consensus regarding the best protocol to treat osteoradionecrosis, LPRF might be an interesting adjuvant to a surgical approach. The use of LPRF is simple and reduces operational costs, time of handling, probability of technical failure, and associated morbidities for patients with osteoradionecrosis.

Chronic sclerosing mediastinitis is a rare disease of unknown etiology, pathologically characterized by chronic inflammation and fibrosis of mediastinal soft tissue. The process is often progressive and can occur either focally or diffusely throughout the mediastinum. This can result in compression of adjacent mediastinal structures, most commonly the low-pressure superior vena cava but also the pulmonary artery and vein, trachca and bronchi, esophagus and can result in a variety of functional and roentgenographic manifestation and occasionally death. We experienced a case of chronic sclerosing mediastinitis of unknown cause, which was confirmed by biopsy with thoracotomy, so reported it with a review of literature.

Idiopathic tracheal stenosis is a type of benign stenosis that possesses specific characteristics but is of unknown origin. It is a rare disease characterized by extensive fibrosis of a portion of trachea, and predominantly found in women. The lesion presents as circumferential fibrotic stenosis that usually occurs at upper trachea and the subglottic larynx, but lower trachea may also be involved. Diagnosis is made from the clinical characteristics accompanide by compatible pathologic features and by exclusion of other etiologies. Conservative management such as laser resection, dilatation and stent insertion can be tried initially, but surgical resection is recommended for definitive treatment due to frequent restenosis and maintenance problems of conservative approach. We report a case of idiopathic tracheal stenosis treated with tracheal resection and anastomosis followed by insertion of a retrievable stent for immediate relief of airway obstruction.

Serum liver enzyme levels are widely used in the clinical diagnosis of liver diseases and the assessment of liver status. They also have epidemiological significance to be prospective risk factors for type 2 diabetes, cardiovascular disease. In the previous study, single nucleotide polymorphisms (SNPs) in several genes have been reported to be associated with serum liver enzyme levels in American population. We aimed to confirm whether the genetic variation of C16orf47 (chromosome 16 open reading frame 47) gene also influence the serum liver enzyme levels in Korean population. We genotyped variants in or near C16orf47 in a population-based sample including 994 unrelated Korean adult. Here, we performed association analysis to elucidate the possible relations of genetic polymorphisms in C16orf47 gene with serum liver enzyme levels. By examining genotype data of a total of 944 subjects in 5 hospital health promotion center, we discovered the C16orf47 gene polymorphisms are associated with serum liver enzyme levels. The common and highest significant polymorphism was rs7203412 (${\beta}$=3.68, P=3.66E-06) with glutamic oxaloacetic transferase (GOT) and rs7203412 (${\beta}$=6.2, P=7.06E-05) with glutamic pyruvate transaminase (GPT) in all group. Furthermore, the SNP rs7203412 was consistently associated with GOT (${\beta}$=6.41, P=6.78E-08) and GPT (${\beta}$=11.53, P=2.81E-06) in men group. Consequently, we found statistically significant SNP in C16orf47 gene that are associated with serum levels of GOT and GPT. In addition, these results suggest that the individuals with the minor alleles of the SNP in the C16orf47 gene may be more elevated serum liver enzyme levels in the Korean population.

Gecko proteins have long been used as anti-tumor agents in oriental medicine, without any scientific background. Although anti-tumor effects of Gecko proteins on several cancers were recently reported, their effect on bladder cancer has not been investigated. Thus, we explored the anti-tumor effect of Gecko proteins and its cellular mechanisms in human bladder cancer 5637 cells. Gecko proteins significantly reduced the viability of 5637 cells without any cytotoxic effect on normal cells. These proteins increased the Annexin-V staining and the amount of condensed chromatin, demonstrating that the Gecko proteinsinduced cell death was caused by apoptosis. Gecko proteins suppressed Akt activation, and the overexpression of constitutively active form of myristoylated Akt prevented Gecko proteins-induced death of 5637 cells. Furthermore, Gecko proteins activated caspase 9 and caspase 3/7. Taken together, our data demonstrated that Gecko proteins suppressed the Akt pathway and activated the intrinsic caspase pathway, leading to the apoptosis of bladder cancer cells.

Factors that modulate cholesterol levels have major impacts on cardiovascular disease. Niemann-Pick C1-like 1 (NPC1L1) functions as a sterol transporter mediating intestinal cholesterol absorption and counter-balancing hepatobiliary cholesterol excretion. The liver receptor homolog 1 (LRH-1) had been shown to regulate genes involved in hepatic lipid metabolism and reverse cholesterol transport. To study whether human NPC1L1 gene is regulated transcriptionally by LRH-1, we have analyzed evolutionary conserved regions (ECRs) in HepG2 cells. One ECR was found to be responsive to the LRH-1. Through deletion studies, LRH-1 response element was identified and the binding of LRH-1 was demonstrated by EMSA and ChIP assays. When SREBP2, one of several transcription factors which had been shown to regulate NPC1L1 gene, was co-expressed with LRH-1, synergistic transcriptional activation resulted. In conclusion, we have identified LRH-1 response elements in NPC1L1 gene and propose that LRH-1 and SREBP may play important roles in regulating NPC1L1 gene. [BMB Reports 2015; 48(9): 513-518]
