We are calling the erupting ground water as drug water or mineral water in Korea and thinking those water and food making water. Authors tried to investigate the evidence of contamination by user on the 10 erupting ground water and gained following results: 1. All of the mineral waters on 10 area in Seoul were unfittable to drinking water standard. 2. In the view of the bacteriology 80% were contaminated by coliform group. 3. The highest value of the free carbon dioxide contents were 652.96 ppm at Sam Sun Mineral Water.

BACKGROUND: Pulmonary complications including pneumonia and pulmonary edema frequently develop in critically ill surgical patients. Lung ultrasound (LUS) is increasingly used as a powerful diagnostic tool for pulmonary complications. The purpose of this study was to report how LUS is used in a surgical intensive care unit (ICU). METHODS: This study retrospectively reviewed the medical records of 67 patients who underwent LUS in surgical ICU between May 2016 and December 2016. RESULTS: The indication for LUS included hypoxemia (n = 44, 65.7%), abnormal chest radiographs without hypoxemia (n = 17, 25.4%), fever without both hypoxemia and abnormal chest radiographs (n = 4, 6.0%), and difficult weaning (n = 2, 3.0%). Among 67 patients, 55 patients were diagnosed with pulmonary edema (n = 27, 41.8%), pneumonia (n = 20, 29.9%), diffuse interstitial pattern with anterior consolidation (n = 6, 10.9%), pneumothorax with effusion (n = 1, 1.5%), and diaphragm dysfunction (n = 1, 1.5%), respectively, via LUS. LUS results did not indicate lung complications for 12 patients. Based on the location of space opacification on the chest radiographs, among 45 patients with bilateral abnormality and normal findings, three (6.7%) and two (4.4%) patients were finally diagnosed with pneumonia and atelectasis, respectively. Furthermore, among 34 patients with unilateral abnormality and normal findings, two patients (5.9%) were finally diagnosed with pulmonary edema. There were 27 patients who were initially diagnosed with pulmonary edema via LUS. This diagnosis was later confirmed by other tests. There were 20 patients who were initially diagnosed with pneumonia via LUS. Among them, 16 and 4 patients were finally diagnosed with pneumonia and atelectasis, respectively. CONCLUSIONS: LUS is useful to detect pulmonary complications including pulmonary edema and pneumonia in surgically ill patients.

We performed 70 proceudres of transarterial chemoembolization (TAE) through extrahepatic collateral vessels (n=27) or parasitic feeders (n=18) in 45 hepatocellular carcinoma patients. The collaterals developed after interruption of the hapatic artery due to repeated TAE(n=17), surgical ligation(n=7) and primary celiac occlusion (n=3). Radiologic findings suggesting the existence of parasitic or collateral supply for hepatocellular carcinoma were 1) a focal defect of Lipiodol retention on CT or plain film after TAE via the hepatic artery, 2) dilated and tortuous vessels around the mass on angiography, 3) persistent elevation of the level of serum alpha fetoprotein or continuous clinical symptoms in spite of sufficient devascularization of the tumor via the hepatic artery, and 4) radiological findings of direct invasion into adjacent organ. The sites of the catheter placement were the inferior phrenic artery (n=19), omental branches (n=16), periportal collaterals (n=6), pancreaticodenal arcade (n=3), gastroduodenal artery (n=3), internal mammary artery (n=2), intercostal artery (n=2), lateral thoracic artery (n=1), bronchial artery(n=1), and colic branches(n=1). Masses feeded by the inferior phrenic and chest wall collaterals were usually located at the dome area of the liver, and the omental and gastroduodenal collaterals developed in the masses located at the inferior tip of the liver. After TAE via collateral vessels, 37 patients underwent follow-up study. In 18 cases(48%), the tumor favorably responded to TAE. Specific complications of collateral TAE were epigastric soreness (n=10), severe shoulder pain (n=4), and embolization of the spinal artery during embolization through the intercostal artey (n=1). In conclusion, various extrahepatic collaterals are important alternative or additional routes for effective chemoembolization in patients with advanced hepatoma, and early recognition of the parasitic supply and the effort to perform TAE via collaterals is very important for effective management of the patients with the hepatoma.

The purpose of this study is to evaluate the efficacy of the balloon bronchoplasty in the treatment of the tuberculous bronchostenosis. Balloon bronchoplasty was performed in thirteen patients with stenosis of the left main bronchus (two with combined left upper and lower lobar bronchostenosis) using a inflatable balloon catheter under a fluoroscopic guide. We analysed the changes in the changes in the severity of dyspnea and wheezing, serial FEV1/FVC as a parameter of the airflow obstruction, and bronchial diameter and lung volume on chest radiographs. The extent of pulmonary tuberculosis was correlated with the improvement of FEV1/FVC. There was an improvement of dyspnea in 69%(9/13), decrease of wheezing in 69%(9/13), significant increase of FEV1/FVC in 18% (2/11). The increase of the bronchial diameter and lung volume were seen in 84%(11/13) and 53% (7/13), respectively. The significant increase of FEVI/FVC was seen in 28% (2/7) of the patients with lung involvement of tuberculosis less than one third of left upper lobe, whereas there was no increase in those of more than one third. There was no complication except transient leukocytosis, fever and blood-tinged sputum. In conclusion, balloon bronchoplasty is effective in the treatment of medically intractable tuberculous bronchostenosis, and can be considered as an initial method of treatment.

This study was designed to evaluate the potential applicability of magnetic resonance imaging (MRI) for the diagnosis of acute renal vein thrombosis. Renal vein thrombosis was experimentally induced by surgical ligation of the left renal vein in a total of 21 rabbits. MRI was performed with a 0.5 Tesla superconductive magnetic system. Spin echo technique was used with varying TR and TE parameters. Spin echo images of the rabbit kidney were analysed for morphology and signal intensity. T1 and T2 relaxation times of the renal cortex and medulla were calculated from the images. After venous ligation, kidneys became enlarged. Low signal band along the outer medulla in T2 weighted images were characteristically shown from 1 hour to 3 days after ligation, Changes of cortex to medullar contrast (CMC) values were significant (p<0.05) in T1 - and T2- weighted images of the ligated side. T1 and T2 relaxation times were significantly prolonged (p<0.05) on the ligated side, both in the cortex and medulla from 1 hour to 2 weeks after the ligation, while T2 relaxation time on the contralateral side was significantly prolonged both in the cortex and medulla 2 weeks after venous ligation. The most useful MRI criteria for the diagnosis of renal vein thrombosis were enlarged renal size, and the low signal band along the outer medulla of ligated kidney. The relative intensity difference between cortex and medulla (CMC) in T1-and T2-weighted images, and T1 and T2 relaxation times were suggested to be the useful MR parameters for the diagnosis of acute renal vein thrombosis.

The T cell responses to hepatitis B surface antigen (HBsAg) were analyzed in acute hepatitis patients, chronic active hepatitis (CAH) patients and asymptomatic carriers. Neither proliferative responses nor substantial cytokine production of peripheral blood mononuclear cells (PBMC) in response to HBsAg was detected. For further studies, HBsAg- reactive T cell lines were prepared from PBMC of the hepatitis patients and asymptomatic carriers. No proliferative response of the T cell lines was observed. Interestingly, however, T cell lines obtained from acute hepatitis patients were found to produce IFN-r, but not IL- 4, in response to HBsAg stimulation, whereas T cell lines obtained from CAH patients and carriers were not. Results of this study suggest that HBsAg-reactive T cells producing Thl type cytokines may play an important role in the viral clearance during acute infections, while defects in those T cells may be responsible for the viral persistency.
