As developing surgical techniques and postoperative cares, a pneumonectomy is a relatively popular surgical method in disease which is not treated completely with other type of pulmonary resection, but a postpneumonectomy complication is a life-threatening serious problem if it occurred. We performed one hundred twenty-five cases of pneumonectomy for treatment of various causes of pulmonary diseases in Kosin Medical College during about ten years, and we experienced 41 cases of postoperative complications in 29 patients, so we analyzed them. The most common complication is an empyema thoracis in 13 cases[10.4%], of which one case combined with bronchopleural fistula died on early postoperative day. Of them except one case, the early postoperative empyema thoracis[within 30 days] were 6 cases, and the late postoperative empyema thoracis[above 30 days] were 6 cases. The main etiologic pathogens were a staphylococcus in early postoperative empyema and a streptococcus in late postoperative empyema, but the most cases were mixed infections with pseudomonas, klebsiella, acinectobacter, and candida. The treatment of postoperative empyema thoracis were that 4 cases were treated with open drainage using chest tube, 7 cases with Clagett`s operation, and 1 case with thoracoplasty. The next common complication was a postoperative serious respiratory insufficiency in 7 cases. And the other complications were massive postoperative bleeding in 5 cases, of which 2 cases advanced to occurrence of postoperative empyema thoracis, and wound disruption in 4 cases, cardiac arrhythmia in 3 cases, contralateral pneumothorax and pneumonia in each of 2 cases, esophagopleural fistula in 1 case. The postoperative deaths were 9 cases[7.2%] of 125 cases, the causes of death were respiratory insufficiency in 6 cases, sepsis in 2 cases, and cardiac arrhythmia in 1 case.

The occurrence and abundance of protozoa at advanced wastewater treatment plant were compared with operating parameters and effluent quality using statistical procedures. In correlation analysis between the distribution of protozoa and operating parameters, the distribution of protozoa was showed the operating condition of plant. Regression analysis between the distribution of protozoa and effluent quality up to 7 days, showed the R-square values of most regression equation were more than 0.6 and constant was higher than slope and could indicate effluent quality from sampling day to 7 days. Once enough data concerning protozoa, operating parameters and effluent has been gathered, the operator has a valuable tool for predicting plant performance and near-future effluent quality based on microscopic examination. Plant operator manipulates operating conditions if he knows near-future data of effluent is deteriorating. Perhaps more importantly it can be used to actually control the plant to adjust the operating conditions to obtain the protozoal populations that have been shown to provide the best effluent quality.

Neuroblastoma is the most common solid malignancy in childhood. However, a neuroblastoma presenting as bilateral and multifocal is very rare. A male newborn weighing 2.7 kg was born by normal vaginal delivery at 39 weeks' gestation to a 27-year-old mother who had a normal pregnancy. He was in good condition at birth but presented palpable masses in the both upper abdomen and both side of the neck. Ultrasound examination showed the lesions to be $3{\times}3cm$ sized calcified mass in right suprarenal area and $5{\times}3cm$ sized homogenous mass in left suprarenal area. The abdominal mass was also examined by computed tomography with similar findings. With the impression of bilateral neuroblastoma or metastatic spread, the laparotomy was performed on the 13th day of life. Frozen section of biopsy of the left neck mass was obtained, which showed neuroblastoma. Intraoperative findings revealed bilateral adrenal masses which were distinct and anatomically separate. Bilateral adrenalectomy was accomplished and the initial postoperative course was uneventful. The patient was discharged for hopeless and expired at age 45 days. We present bilateral adrenal neuroblastoma considered to be simultaneous occurrence rather than metastases from one site to another.

Ninety-two isolates of Fusarium species were obtained from Chinese corn samples. The predominant Fusarium species isolated from corn seeds were F. moniliforme, F. proliferatum, F. oxysporum and F. subglutinans, and all 13 species were identified. Each isolate was grown on autoclaved wheat grains and wheat cultures were fed by twenty-one-day-old female rats for the toxicity test. Twenty-six out of 92 isolates caused the death accompanying feed refusal, severe weight loss, liver damage, and hemorrhages in the stomach and intestines. Of the toxigenic isolates, 17 isolates of F. moniliforme, 4 of F. oxysporum, 3 of F. proliferatum, and one of each F. sporotrichioides and unknown species were lethal to rats. The analyses of fumonisin B1 production of the 26 toxigenic Fusarium isolates were carried out by thin layer chromatography and high-performance liquid chromatography, and fumonisin B1 was confirmed by mass spectrometry. Fumonisin B1 was produced in wheat culture at levels ranging from 280 $\mu\textrm{g}$/g to 3,952 $\mu\textrm{g}$/g by all of toxigenic F. moniliforme and F. proliferatum, but by none of the other toxigenic Fusarium species. The present results suggest the high possibility of natural occurrence of fumonisin B1 in corn samples imported from China.

A female, 14-year-old, African penguin (Spheniscus demersus) weighing 2.5 kg with the anorexia for one day and 22 months history of bumblefoot was found dead in aquarium. Grossly, severe bumblefoot in the central surface of the right foot, severe enlarged liver and kidneys with orange color were observed. Histopathologically, pinkish amorphous materials were accumulated in liver, spleen, kidney, and stomach. The pinkish materials in the liver, kidney, spleen, and stomach were confirmed as amyloid with typical orange color reactions using Congo red stain under the light microscope and with bright red color expressions using Congo red stain under the fluorescence microscope. Based on the typical gross and histopathologic findings and special staining, this case was confirmed as systemic amyloidosis. A long period time of moderate bumblefoot might be closely associated with the occurrence of systemic amyloidosis in the captive penguin.

This study was conducted to investigate effects of honeybee venom (Apis mellifera L. BV) on the calving, the growth performance and blood chemistry occurrence of Hanwoo calves. A total of twenty, a 3 day old male experimental calves were allocated into four groups, BV treated (0.05 mg/kg, 0.1 mg/kg and 0.2 mg/kg BV, n=5, respectively) and non-treated (n=5, Control) of Hanwoo calves in Icheon, Kyonggi province. Treatment of BV in calves increased body weight and weight gain during 60 days compared with control group. The concentrations of IgG in blood were significantly increased in BV groups compared with control at 60 days after treatment with BV. Cholesterol and glucose concentrations in BV group were significantly lower with control at 60 days. There were no differences in plasma biochemical components including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphate (AKLP), total protein, albumin, globuline, total bilirubin, creatinine, blood urea nitrogen (BUN) and $Ca^+$. In conclusion, the BV treatment had effect on growth, the score of the calf scours and blood biochemical profile.

Fourty-three infants underwent intracardiac repairs within the first 12 months of life. Mean age was 7 months and mean weight was 6.7 kg. A quarter of them were below 5 kg. Overall mortality including complex anomalies was 17.9%. Thirty-four infants with a ventricular septal defect[VSD were treated. Three infants[8.8% died in the early postoperative period, but only one[3.7% of the infants without having associated lesions was dead. VSD was repaired either by the incision on the right atrium, pulmonary artery, or right ventricle. Postoperative right bundle branch block[RBBB occurrence were different according to the approach: 30.8 % in pulmonary arteriotomy, 37.5 % in atriotomy, and 42.8 % in ventriculotomy. Surgically induced heart block did not occur in any patient, but 10 had temporary arrhythmia, and 11 patients were under temporary pacing from one day to 4 days without any persisting rhythm disturbances. Pulmonary hypertension was present in 29 infants preoperatively, and seven of them developed postoperative elevation of the pressure. Infants complicated with pulmonary hypertensive crisis were managed successfully. Inotropics were necessary in 55.8 % of the infants and vasodilators in 37.2 %. Platelet transfusion were needed in 10 cases who required 272 ml in average, but one who died from sepsis consumed 5,370cc of platelets. And we discuss complications and causes of deaths.

Purpose: The purpose of this study was to investigate both the occurrence status of emergency vehicles traffic accidents and contents of the experiences of emergency medical technicians (EMTs) in fire station. Methods: A self-reported questionnaire was completed by 451 EMTs in fire stations in 6 cities provinces from February 9, 2017 to February 27, 2017. Results: Of 451 EMTs, 207 (45.9%) had traffic accidents experience. Regarding environment-related features, results indicated hour (12~18 hours), place (national highway), traffic flow (smooth), weather (clear), season (winter), and day (Friday). Regarding correlation analysis of differences in the number of ambulance traffic accidents pursuant to general features of accident-experienced drivers as a human factor, there were no significant differences in recruitment, driving careers of regular cars, driving careers of fire engines, and class but there were significant differences in fire-fighting careers. Accident experience in the group with careers over 6 years and less than 10 years higher than in the other groups. Conclusion: Efforts to expand fire engine driving education programs for the prevention of traffic accidents involving 119 emergency vehicles are required.
