A 2-year-old, female, Maltese dog (3.2 kg of body weight) was referred to the Veterinary Medical Teaching Hospital, Chungnam National University with vomiting, anorexia and depression. Twelve hours prior to the onset of clinical signs, the dog ingested some grape skins (about 60 g). Physical examination at the time of presentation showed peripheral edema and mucous pallor. Blood and blood chemical analysis revealed anemia and moderate azotemia with elevated blood urea nitrogen (107.2 mg/dl), creatinine (6.3 mg/dl) and hyperphosphatemia (11.3 mg/dl). Echogenicity of renal cortex were observred by ultrasonography. The dog was diagnosed as acute renal failure occurred by grape skin toxicosis. The dog was treated with supportive care such as fluid therapy, diuretics (furosemide) and phosphorus binder (almagate). A normal condition of blood and blood chemical findings and clinical signs was observed at five days after treatment, and prognosis is good to date.

Care of patients with sepsis has improved over the last decade. However, in the recent two years, there was no significant progress in the development of a new drug for critically ill patients. In January 2011, it was announced that the worldwide phase 3 randomized trial of a novel anti-Toll-like receptor-4 compound, eritoran tetrasodium, had failed to demonstrate an improvement in the mortality of patients with severe sepsis. In October 2011, Xigris (drotrecogin alfa, a recombinant activated protein C) was withdrawn from the market following the failure of its worldwide trial that had attempted to demonstrate improved outcome. These announcements were disappointing. The recent failure of 2 promising drugs to further reduce mortality suggests that new approaches are needed. A study was published showing that sepsis can be associated to a state of immunosuppression and loss of immune function in human. However, the timing, incidence, and nature of the immunosuppression remain poorly characterized, especially in humans. This emphasizes the need for a better understanding of sepsis as well as new therapeutic strategies. Many clinical experiences of the extracorporeal membrane oxygenator (ECMO) treatment for adult acute respiratory distress syndrome (ARDS) patients, which is caused by the H1N1 influenza A virus, were reported. The use of ECMO in severe respiratory failure, particularly in the treatment of adult ARDS, is occurring more commonly.

It is difficult to differentiate acute skin failure (ASF) from pressure ulcer (PU). ASF is defined as unavoidable injury resulting from hypoperfusion caused by severe dysfunction of another organ system. We describe a case of ASF mistaken as PU that resulted in a legal dispute. A 74-year-old male patient was admitted to our intensive care unit with sepsis due to bacterial pneumonia. Despite the use of air cushions and regular position changes, skin ulcerations occurred over his occiput, back, buttock, elbow, and ankle. After improvement in his general condition, he was transferred to the department of plastic and reconstructive surgery. Debridement was performed immediately, followed by conservative treatment (including a vacuum-assisted closure device) for 6 weeks. The buttock and occiput wounds were treated surgically. Despite complete healing, his caregivers sued the hospital for failing to prevent PU formation. ASF is a pressure-related injury resulting from hemodynamic instability due to organ system failure. Unlike PU, ASF may occur despite the implementation of all appropriate preventive measures. Furthermore, misdiagnosis of ASF as PU can lead to litigation. Therefore, it is critical for the proper diagnosis to be made quickly, and for physicians to explain that ASF occurs despite proper preventative treatment.

The purpose of this study was to investigate the effect of acid treatment of fluoride applied dentin surface with various concentrations of phosphoric acid for various periods of time on dentin bonding. Dentin specimens prepared from freshly extracted bovine mandibular anterior teeth were divided into fluoridated and nonfluoridated groups. Specimens of nonfluoridated group were pretreated with 10% phosphoric acid for 15 seconds. Those of fluoridated groups were treated with 2% sodium fluoride or 2% stannous fluoride solution for 5 minutes and stored in $37^{\circ}C$ distilled water for 3 days, followed by phosphoric acid treatment. The concentrations of phosphoric acid were 10%, 32% or 50% and the treatment periods of time were 15, 30 or 60 seconds. All the specimens were bonded with All Bond$^{(R)}$ 2 and Bisfil$^{TM}$ composite resin. After bonded specimens were stored in $37^{\circ}C$ distilled water for 24 hours, tensile bond strengths of each specimens were measured and the pretreated dentin and the fractured dentin surfaces were examined under the scanning electron microscope. The results were as follows : The tensile bond strengths from the fluoridated groups were significantly lower than those from the nonfluoridated group when the concentrations of phosphoric acid and the treatment periods of time were equal in all the groups (p<0.05). In general, the higher the concentration of phosphoric acid and the longer the treatment period of time for acid etching on the fluoride applied dentin surface, the higher were the bond strength values. Recovery of bond strength of the dentin bonding agent was better in the NaF applied group than in the $SnF_2$ applied one. SEM findings of NaF applied and $SnF_2$ applied dentin surfaces demonstrated reaction product-covered and partially or completely obstructed dentinal tubules. SEM findings of dentin surfaces fluoridated for 5 minutes followed by etching showed wider tubular openings and more clean dentin surfaces when dentin was etched with higher concentration of phosphoric acid for longer period of time. On the SEM observations of the fractured dentin-resin interface, the etched specimens of fluoridated group showed an adhesive failure mode when the concentration of phosphoric acid and the treatment period of time were same as in the nonfluoridated group. As the concentration of phosphoric acid and the treatment period of time increase during acid etching, the cohesive failure area increased. However, excessive acid etching caused adhesive failure.

In the early days of open heart surgery, acute respiratory failure following extracorporeal circulation was a significant deterrent to an uncomplicated recovery. Although a marked improvement in prevention and treatment of postoperative respiratory failure has been achieved, the problem has not been completely eliminated and continues to be a causative factor in morbidity and mortality Fates following open heart surgery. We have attempted to evaluate postoperative respiratory failure in patients undergoing cardiac operation with the aid of extracorporeal circulation. Our series comprised 92 patients who underwent elective open heart surgery at the Department of Thoracic and Cariodvascular Surgery, School of Medicine, Kyungpook National University, from January, 1980 to December, 1982. In our study, the overall incidence of acute respiratory failure following open heart surgery was 18.8 percent. The duration of extracorporeal circulation in a series of 18 patients who developed postoperative respiratory failure [Group B] was longer in the mean value [120.3 minutes] than the uncomplicated 74 patients [Group A] [85.8 minutes]. The duration of artificial ventilation after open heart surgery in Group A averaged 13.4 hours as contrasted with 76.5 hours in Group B. In Group B, the inspired oxygen concentration [FiO2] in artificial ventilation was continued in the higher level than Group A until 18 hours after operation. Upon pulmonary function test performed pre-and postoperatively, residual volume[RV], RV/TLC and FEV 1.0/FVC were remained essentially unchanged following extracorporeal circulation, whereas forced vital capacity [FVC], FEV 1.0 and FEF 25-75% were significantly decreased in the early postoperative days. The incidence of acute respiratory failure was significantly higher in a series of patients who developed postoperative complications, such as re- exploration due to massive bleeding, low cardiac output, acute renal failure and arrhythmias. A total of 9 patients died, giving an overall mortality was 33.3 percent whereas the mortality was only 1.1 percent for patients without respiratory failure.

Purpose: Rhabdomyolysis is one of the most important complications of pesticide intoxication. It affects a patient's clinical prognosis and can cause acute renal failure. It is important that patients diagnosed with pesticide intoxication receive an accurate initial diagnosis and proper treatment to prevent significant complications. This study's objective was to investigate and confirm related factors causing acute renal failure by verifying clinical observations and laboratory findings collected following pesticide intoxication. Methods: A retrospective analysis was made of 734 patients who presenting to our emergency medical center after ingesting pesticides between January 2006 and December 2008, Of these, 513 patients were selected for the study. Two hundred and twenty-one patients were excluded because of paraquat intoxication, age (if under 18), or chronic renal failure. Seventy-four patients were diagnosed with rhabdomyolysis, based on serum creatinine phosphokinase levels were > 1,000U/L. Acute renal failure was diagnosed when creatinine levels were > 2.0 mg/dL. Results: Among the 74 patients diagnosed with rhabdomyolysis, 26 (35.1%) experienced acute renal failure. The most meaningful related factor in the prediction of acute renal failure was initial arterial pH and creatinine level. Conclusion: Initial arterial pH and creatinine level are predictors of complications such as acute renal failure in patients with rhabdomyolysis.

PURPOSE. To evaluate the effect of various surface treatments on the surface structure and shear bond strength (SBS) of different ceramics. MATERIALS AND METHODS. 288 specimens (lithium-disilicate, leucite-reinforced, and glass infiltrated zirconia) were first divided into two groups according to the resin cement used, and were later divided into four groups according to the given surface treatments: G1 (hydrofluoric acid (HF)+silane), G2 (silane alone-no heat-treatment), G3 (silane alone-then dried with $60^{\circ}C$ heat-treatment), and G4 (silane alonethen dried with $100^{\circ}C$ heat-treatment). Two different adhesive luting systems were applied onto the ceramic discs in all groups. SBS (in MPa) was calculated from the failure load per bonded area (in $N/mm^2$). Subsequently, one specimen from each group was prepared for SEM evaluation of the separated-resin-ceramic interface. RESULTS. SBS values of G1 were significantly higher than those of the other groups in the lithium disilicate ceramic and leucite reinforced ceramic, and the SBS values of G4 and G1 were significantly higher than those of G2 and G3 in glass infiltrated zirconia. The three-way ANOVA revealed that the SBS values were significantly affected by the type of resin cement (P<.001). FIN ceramics had the highest rate of cohesive failure on the ceramic surfaces than other ceramic groups. AFM images showed that the surface treatment groups exhibited similar topographies, except the group treated with HF. CONCLUSION. The heat treatment was not sufficient to achieve high SBS values as compared with HF acid etching. The surface topography of ceramics was affected by surface treatments.

In wafer level molding progress, the thermal releasing failure phenomenon is shown up as the important problem. This phenomenon can cause the problem including the warpage, crack of the molded wafer. The thermal releasing failure is due to the insufficiency of adhesion strength degradation of the molding tape. To solve this problem, we studied experimental method increasing the release property of the molding tape through the plasma surface treatment on the wafer substrate. In this research, the vacuum plasma treatment system is used for release property improvement of the molding tape and controls the operating condition of the hydrophilic($O_2$, 100kW, 10min) and hydrophobic($C_2F_6$, 200kW, 10min). In order to perform the peeling test for measuring the releasing force precisely, we remodel the micro scale material property evaluation system developed by Korea institute of industrial technology. In case of hydrophilic surface treatment on the wafer substrate, we can figure out the releasing property of molding tape increase. In order to grasp the effect that it reaches to the release property increase when repeating the hydrophilic treatment, we make an experiment with twice treatment and get the result to increase about 12%. We find out the hydrophilic surface treatment method using plasma can improve releasing property of molding tape in the wafer level molding process.

Incidence of tooth impaction varies from 5.6 to 18.8% of the population. Failure of eruption of the first and second permanent molars is rare; the prevalence in the normal population is 0.01% in case of the first permanent molar, and 0.06% in case of the second permanent molar. Permanent molars are particularly important for providing sufficient occlusal support and co-ordinating facial growth. Failure of eruption of permanent molars may result in various complications such as decrease in vertical dimension, posterior open bite, extrusion of antagonistic teeth, resorption and inclination of adjacent teeth, formation of cyst and so on. Treatment options of impacted teeth are periodic observation, surgical exposure, surgical exposure with subluxation, orthodontic relocation, and surgical extraction before prosthetic treatment. Early diagnosis and treatment are important, because delayed treatment induces various problems such as decreased spontaneous eruptive force, decreased successful percentage, increased treatment period, increased various complications. Prevalence of the failure of mandibular first molars is rare but eruptive guidance before extraction of impacted teeth is necessary due to importance of permanent molars. We reported two cases of surgical exposure of impacted mandibular first molar. In these cases, we could observe different result of the impacted mandibular first molar after surgical exposure.
