Meconium peritonitis is an aseptic peritonitis caused by spill of meconium in the abdominal cavity through one or several intestinal perforations which have taken place during intrauterine life or early neonatal life. We experienced three cases of meconium peritonitis with ileal perforation in two cases 1 day-old male neonate and 2 day-old male neonate, respectively, which had the chief complaint of vomiting and abdominal distension. Literatures are reviewed, briefly.

We aimed to evaluate the long term trantment of enalapril on the vascular response in the isolated aorta, and in anesthetized or pithed spontaneously hypertensive rats(SHR). In the isolated aorta, the increase in tension provoked by addition of KC1 16.7mM was attenuated by enalapril treatment(3mg/kg/day for 6 weeks), whereas the increment by addition of NE 0.1uM tension was not influenced. The frequency-dependent vasoconstricution induced by electrical field stimulation of aorta was also attenuated by enalapril treatment. In pithed SHR, the frequency-related hypertension provoked by electrical stimulation(10sec, 1ms with 40V) of sympathetic pregnglionic nerve was also attenuated by enalapril treatment. Neither dose-related vasorelaxation by acetylcholine addition in the aorta nor decrease of DBP by intravenously(i.v.)-injected aetylcholine was altered by enalapril treatment. However, beta2-agonist, salbutamol-induced vasorelaxation in enalapril-treated group, was more remarkable than that in control group. The hypotension by i.v.-but not by intracerebroventricularly-injected salbutamol strengthened by enalapril treatment. These results suggest that the suppression of development of hypertension by enalapril treatment may result from the reduction of adrenergic neurotransmission and activity to voltage dependent calcium channel by acting on vascular smooth muscle itself.

Comamonas testosteroni and Acinetobacter guillouiae are gram-negative bacilli of low virulence that are widely distributed in nature and normal flora. Despite their common occurrence in environments, they rarely cause infectious disease. We experienced a case of septic shock by C. testosterone and A. guillouiae, and isolated them by 16S ribosomal RNA sequencing method from the blood cultures of a previous healthy female during postoperative supportive care. This is the first case of septic shock required ventilator care and continuous renal replacement therapy due to these organisms in Korea.

6.The Covering of the Suture Area with an Absorbable Cellulose Mesh and Fibrin Glue in Bullectomy of Primary Spontaneous Pneumothorax.
The Korean Journal of Thoracic and Cardiovascular Surgery 2001;34(5):393-398
BACKGROUND: To evaluate the efficacy of cellulose mesh with fibrin glue to decrease recurrence rate after bullectomy for a treatment of primary spontaneous pneumothorax. MATERIAL AND METHOD: 222 patients underwent a bullectomy for primary spontaneous pneumothorax in our institute between April. 1996, and June, 2000. Patients were divided into four groups by period and operation method. Group 1(n=25) underwent video-assited thorasic surgery(VATS) and mechanical pleurodesis between 1996 and 1997. Group 2(n=53) underwent axillary thoracotomy and mechanical pleurodesis between the same period. Group 3(n=110) undewent VATS and mechanical pleurodesis between 1998 and April, 2000. Group 4(n=34) underwent VATS and reinforcement with absorbable cellulose mesh and fibrin glue between 1998 and June, 2000. The data of recurrence rate, duration of air leakage, and duration of chest tube drainage evaluated by each group were compared and analysed using general linear model procedure. RESULT: There were 203 men and 19 women. Mean age was 23.2+9.6 years. Recurrent rate in group 1 was 25%, 3.8% in group 2 and 4.5% in group 3. Threre was no recurrence of pneumothorax in group 4. All recurrent cases after bullectomy were developed at the period of surgeon' s experience of bullectomy if it was less than 2 years. Chest tube indwelling period in group 4 was shorter compared to that of group 1,group 2(p<0.0006) and group 3(p<0.0001). There was no postoperative air- leakage in group 4. Recurrence rate was higher in minimal and moderate size pneumothorax than that in massive pneumothorax. In the 12 recurred cases, nine cases had blebs near the suture line. CONCLUSION: The covering of the suture area with an bsorbable cellulose mesh and the application of the fibrin glue on the mesh in wedge resection of blebs are effective and shorter tube indwelling period was resulted. There were no postoperative air leakage through chest tube after this additional procedure and no recurrence in short term follow-up period. Recurrence rate was higher in small size pneumothorax than that in large sizepneumothorax. Recurrence rate was also influenced by the experience of surgeon.

The increasing number of patients with depression is a serious social issue in contemporary Korean society. To fully understand the pathophysiology of depression, this paper reviewed how depression affects the decision making process of humans. Various recent studies in behavioral economics, mathematics, medicine, and neurobiology have shown how humans make decisions and how emotional disturbances, such as depressive disorder, affect this process. There has been great progress in behavioral economics during this decade, and numerous experiments have been designed to evaluate decision making process in humans. In general, economic decision making is evaluated using the Iowa Gambling Task, and social decision making is assessed using the ultimatum game. Numerous research studies have analyzed the performance and reaction of patients with depression in these games. As a result of the advancement of neurophysiology, research has successfully identified the part of the brain that causes the specific results of tests being conducted on patients with depression. Meanwhile, computational neuroscientists have established decision making models based on bayesian framework. These models also match with the neuroanatomy. Although a large part remains unclear, researchers look forward to achieving a better understanding in depression by analyzing the distinct patterns of responses that patients under depression show in the experiment of behavioral economics.

BACKGROUND: Patients with sinus rhythm, the left atrial appendage(LAA) appeared as a vigorously contracting structure and the blood flow patterns of LAA showed biphasic configuration. However, patients with AF rhythm the blood flow showed irregular or no configuration in doppler echocardiographic study. The purpose of this study is to evaluate relationship between the blood flow patterns of LAA with the presence of spontaneous contrast(SC) and thrombi in LAA. METHODS: We performed TEE and TTE simultaneously to 58 consecutive patients who had native mitral valve disease or mitral prosthesis. Spontaneous contrast(SC) and the presence and location of LAA thrombi were evaluated during TEE and left atrial dimension(LAD) & ejection fraction(EF) were evaluated during TTE. We divided the whole subjects into three groups according to the blood flow patterns ; regular pattern(Group 1), irregular pattern(Group 2), no flow pattern(Group 3). RESULTS: 1) Blood flow within the left atrial appendage is divided with three groups among of them, atrial fibrillation have two blood flow patterns. 2) Peak prositive & negative flow velocity within LAA in AF rhythm groups were slower than normal sinus rhythm group.(p<0.01) 3) Left atrial dimension in group 3 is significantly larger than others groups.(p<0.01) 4) Spontaneous contrast(SC) with LAA could be detected in 2(6.8%) of the 29 patients of group 1, 6(31.5%) of the 19 patients of group 2, 10(100%) of the 10 patients of group 3. Incidence of SC within LAA in group 3 is significantly higher than others groups. 5) LAA thrombi could be detected in 1(3.4%) of the 29 patients of group 1, 1(5.2%) of the 19 patients of group 2, 3(30%) of the 10 patients of group 3. Incidence of LAA thrombi is significangly higher than other groups. CONCLUSIONS: We can suggest that blood flow within LAA is divided into three groups according to the blood flow patterns, and spontaneous contrast and thrombi in LAA were closely related with the blood flow pattern.

The relationship between the intestinal histopathology and number and position of intraepithelial lymphocytes (IEL) was observed chronologically in the small intestine of rats experimentally infected with Metagonimus yokogawai. Fifteen Sprague-Dawley rats were orally infected each with 3,000 metacecariae, and 3 were kept uninfected for controls. Three rats each were sacrificed on the day 5, 10, 15, 24 and 70 post-infection (PI) and samples of the small intestine, 5 cm, 10 cm, 20 cm and 70 cm posterior to the pylorus were taken. The samples were processed routinely and stained with Giemsa. The intestinal histopathology was severe during the day 5-15 PI and characterized by villous atrophy, crypt hyperplasia, and decrease of villus/crypt height ratio. After the day 24 PI, the intestinal lesions showed some tendency of recovery. The number of IEL increased at the early stage of infection, but decreased thereafter to a lower level than that of controls, with progression of the pathological changes. Then, the IEL number began to increase again after the day 24 PI. In control rats, the great majority of the IEL were located at the basal region of the epithelium. During the early stage of infection, however, a considerable proportion of IEL was found to have moved to the intermediate or apical region of the epithelium. From the above results, it is suggested that the change of IEL number and position during the course of M. yokogawai infection should be closely related to the progression and recovery of the intestinal histopathology.
