Background: When it comes to esophageal cancer operations, the prevalence of anastomotic complications that adversely affect quality of life is related to the type of anastomotic procedure and the operative site. We studied outcomes related to a safe anastomotic method used in Ivor Lewis esophagogastrectomy for preventing anastomotic leakage and stricture formation. Material and Method: Between May 2003 and April 2007, 18 patients with esophageal cancer underwent this type of esophagogastrectomy. Four people were lost to follow-up. There were 17 men (94.4%) and 1 woman. The mean patient age was 61 years (range, $46{\sim}73$ years). Result: The mean follow-up period was 17.2 months (range, $1{\sim}45$ months). There was no anastomotic leakage. There was one benign anastomotic stricture (5.6%) requiring esophageal balloon dilatation, which was accomplished with a 25 mm circular stapler. Conclusion: We experienced relatively good postoperative results using a safe anastomotic method in the Ivor lewis operation for preventing anastomotic complications. These results suggest that this anastomotic method is effective in reducing the incidence of benign anastomotic complications.
Background: Usually, lumbar epidural block is performed on the $L_{3-4}$ interspace. This study was designed to evaluate the analgesic efficacy and shortening of labor duration comparing the $L_{1-2}$ and $L_{3-4}$ interspace epidural blocks in nulliparous normal vaginal deliveries and then investigates side effects following the blocks. Methods: Eighty healthy nulliparous women were divided into two groups, $L_{1-2}$ (n = 40) and $L_{3-4}$ (n = 40). Epidural blocks, lumbar epidural block were performed at the $L_{1-2}$ and $L_{3-4}$ interspace with a catheter advancing 3 cm cephalad. The initial dose of 12 ml (0.167% bupivacaine, fentanyl $50{\mu}g$ and clonidine $75{\mu}g$) was injected epidurally at 4 cm dilatation of cervix and severe pain of labor. If a visual analogue scale (VAS) score was more than 4 points, an additional dose was administered epidurally using the same volume as the above mentioned, but with the exception that the bupivacaine was diluted to 0.1 percentage. The maternal blood pressure, pulse rate, respiration rate and fetal heart rate were measured at 10 min intervals for the first 30 min, at 15 min interval for the next 30 min and at 30 min interval for the last one hour following the blocks. The duration of the first (active) and second stages of labor was counted and the neonatal Apgar score was recorded at one and five min after delivery. The degree of motor block, pruritus, nausea and vomiting were also noted. Results: The patients in group $L_{1-2}$ had lower pain scores than group $L_{3-4}$ at 5, 20, 30, 60 mins. The duration of 1st and 2nd labor stage in the $L_{3-4}$ epidural block were $272{\pm}33.5$ min, $49.2{\pm}27.4$ min respectively but those in the $L_{1-2}$ epidural block were $253.5{\pm}32.5$ min, $37.3{\pm}22.3$ min, respectively. Conclusions: We concluded the analgesic efficacy and shortening of labor duration in $L_{1-2}$ epidural block was better than those in $L_{3-4}$ epidural block. Maternal hemodynamic change, motor block. pruritus, nausea, vomiting and Apgar score showed no significant differences between the two groups.

Congenital hereditary disease is in devided into Infantile type and Adult type, Adult type is hidden for many years and keeps normal renal function till middle age. Cyst is stimultaneously made in both sides and becomes lowered in renal function in 30's to 40's. Infantile type is generally born with the big kidneys, renal failure, undergrowth of intrahepatic bile duct. Both infantile and childhood type have ureteral dilatation and portal hypertension In infantile type, it is mostly developed into renal failure, but generally faces death as a result of hepatic disease. The reason of death is that an abnormal condition of recessive autosome affects the liver and kidneys. While the incidence of infantile type is rare as $0.017{\sim}0.07%$ and it is autosomal recessive heredity, Adult type can rarely exist in infantile period. Though it exists in middle period, 50% of patients can live for 2-4 years after the first symptom incidence and 25% can less than 2 years. It is hard to cure completely in medicine and surgery. Three difficulties in familial incidence are comparative decrease of the donor who have no affection on renal transplantation. For another consideration it is to show the family history for several generations. We, the Med. Dept. of Dae Han Kyouk Life Insurance Co. Ltd., used the ultrasonic apparatus in diagnosing the one case of adult type bilateral polycystic kidney and then doubted the family history. As a result of inspecting the family we experienced bilateral polycystic kidney from 3 persons out of 4 who can be inspected. The results are as follows: 1) We could confirm the polycystic kidney from 3 persons out of 4(75%). 2) Then when they came for check up, chief complaint was the pain in all 3 cases(100%). 3) Accompanying disease was hypertension in 2 cases(67%). 4) In early disease incidence, we couldn't observe the specific change in pathological opinion. 5) All 3 cases are not accompanied with cystic lesion in liver, spleen, pancreas.

Purpose: To determine the clinical manifestations and outcomes of patients with tracheoesophageal fistula (TEF) and esophageal atresia (EA) born at a single neonatal intensive care unit. Methods: A retrospective analysis was conducted for 97 patients with confirmed TEF and EA who were admitted to the neonatal intensive care unit between 1990 and 2007. Results: The rate of prenatal diagnosis was 12%. The average gestational age and birth weight were $37^{+2}$ weeks and $2.5{\pm}0.7kg$, respectively. Thirty-one infants were born prematurely (32%). Type C was the most common. The mean gap between the proximal and distal esophagus was 2 cm. Esophago-esophagostomy was performed in 72 patients at a mean age of 4 days after birth; gastrostomy or duodenostomy were performed in 8 patients. Forty patients exhibited vertebral, anorectal, cardiac, tracheoesophageal, renal, limb (VACTERL) association with at least 2 combined anomalies, and cardiac anomaly was the most common. The most common post-operative complications were esophageal stricture followed by gastroesophageal reflux. Balloon dilatation was performed for 1.3 times in 26 patients at a mean age of 3 months. The mortality and morbidity rates were 24% and 67%, respectively, and the most common cause of death was sepsis. The weight of approximately 40% patients was below the 10th percentile at 2 years of age. Conclusion: Mortality and morbidity rates of patients with TEF and EA are high as compared to those of infants with other neonatal surgical diseases. Further efforts must be taken to reduce mortality and morbidity and improve growth retardation.
The purpose of this study was to evaluate the influence of phenobarbital(PB) on hepatotoxic effect of carbon tetrachloride($CCl_4$) which induces centrilobular necrosis in liver. Rats were injected intraperitoneally $CCl_4$ dissolved in olive oil by a dose of 0.4mg/kg. For change related to PB pretreatment, rats were injected $CCl_4$ 0.4mg/kg after PB pretreatment. The liver samples were taken in 6, 12, 24, 48, 72, and 120 hours after $CCl_4$ and/or FB injection. Extracted liver tissue was examined with light and electron microscopes. The results were sumarized as follows : 1. Light microscopic findings : In $CCl_4$ group, centrilobular necrosis developed from 6 hours after injection, was the most severe in 48 hours, and recovered after 72 hours. In addition to necrosis, fatty change and pale cell change were accompanied. In PB-$CCl_4$ group, necrosis occurred from 6 hours after $CCl_4$ injection and continued to 72 hours, and the degree of necrosis was more severe than that of $CCl_4$ group and pale cell change was decreased. 2. Electron microscopic findings: In $CCl_4$ group, the early principal change was clumping and vesicular dilatation of endoplasmic reticulum. In PB-$CCl_4$ group, the degenerative change of endoplasmic reticulum was aggrevated and the mitochondria also revealed severe degenerative change. According to the results, it was revealed that $CCl_4$ hepatotoxicity primarily began with the damage of endoplasimic reticulum, then damage of other cell organelles and cell necrosis followed, and these cytotoxic effects were aggrevated by PB pretreatment.

Purpose : Kawasaki disease(KD) is rare in infants <3 months of age. In this younger group, the diagnosis may be delayed due to lack of most of the clinical criteria, resulting in a high risk of cardiac complications. We examined clinical characteristics in these patients for early recognition and treatment. Methods : We conducted a retrospective study on the infants with KD aged three months or younger treated at our hospital from January 1998 to July 2002. Results : Of a total of 291 patients treated during the study period, 11(3.8%) were three months old or younger. Of the 11 patients, 10 had atypical presentations. Infants had fewer of the accepted criteria, and the most common findings were fever(100%) and oral mucosal changes(72.7%). Erythema at the site of BCG inoculation was observed in six of the 11 patients(unknown in the remaining five). This feature proved a definite diagnostic clue in two patients in whom cardiac complications developed in the subacute phase. Cardiac complications were found in six patients(54.5%) : three had coronary dilatation, two had coronary wall irregularity, and one had mitral valve prolapse with regurgitation. Defervescence occurred within $1.1{\pm}0.3day$ in 10 of the 11 patients treated with intravenous immunoglobulin(IVIG) and one was given a second course of IVIG. Echocardiographic abnormality persisted in only one patient with mitral regurgitation at the 6-month follow-up. Conclusion : Most patients with KD younger than three months of age have atypical presentations and a high complication rate. For early diagnosis, erythema at the BCG inoculation site, if present, could be used as a valid diagnostic clue to atypical KD in this age group.

A 67 years old male patient was admitted with back pain that had recurred from 6 months previously. Eleven years previously, he underwent stent grafting at the descending thoracic aorta for a chronic Stanford type B aortic dissection. The preoperative computed tomography showed aortic dissection from the origin of the left subclavian artery to the bifurcation of the abdominal aorta, and there was a type I endoleak at the proximal portion of the stent graft and aneurysmal dilatation of the descending aorta. A hybrid endovascular repair was successfully performed, and this involved debranching and rerouting the aortic arch vessels under extracorporeal cardiopulmonary bypass and then this was followed 13 days later by stenting in the ascending aorta, the aortic arch and the descending aorta. The postoperative computed tomography showed complete exclusion of the type I endoleak. After discharge, he has been followed up for 8 months without any problems.
The purpose of this study is to investigate the vasodilatation effect of kirenol isolated from Sigesbeckia pubescens on the rabbit basilar artery. In this study, to determine the vasodilatation effect of kirenol on the rabbit basilar artery, arterial rings with intact or damaged endothelium were used for the experiment. And used an organ bath and force transducer were contracted by endothelin. Kirenol, major active constituents of S. pubescens, showed a moderate vasodilatation effect on the basilar arteries of rabbits. Therefore, treatment with kirenol may selectively accelerate cerebral blood flow through dilatation of the basilar artery. This result suggests a potential role of kirenol isolated from S. pubescens as a source of vasodilatation agent.
In order to differentiate the gastric tubular dilatation of olive flounder, Paralichthys olivaceus, from an atrophic change, a series of histological studies was carried out for normal gastric gland, naturally occurring and histamine-induced dilated glandular tubules. Normal glandular tubules were histologically quite similar to those already reported from other fish species. Naturally occurring, dilated gastric glandular tubules had the epithelial characteristics suffering from atrophy under light microscope, which was also the case in the histamine-induced gastric gland. But on semi-thin sections the area corresponding to the empty space of dilated lumina were actually shadowed with relatively bright area. Under transmission electron microscope this brightly shadowed area turned out to be an area tightly packed with abundant, slender cytoplasmic processes in both cases. These results strongly suggested that the dilative gastric glandular tubules under light microscope might be a morphological change indicating increased glandular activity rather than a pathologic atrophic change.

Purpose: To determine whether the swelling and mechanical properties of osmotic self-inflating expanders allow or not the induction of intraoral soft tissue expansion in dogs. Methods: Three different volumes (0.15, 0.25, and 0.42 mL; referred to respectively as the S, M, and L groups) of soft tissue expanders (STEs) consisting of a hydrogel core coated with a silicone-perforated membrane were investigated in vitro to assess their swelling behavior (volume swelling ratio) and mechanical properties (tensile strength, tensile strain). For in vivo investigations, the STEs were subperiosteally inserted for 4 weeks in dogs (n=5). Soft tissue expansion was clinically monitored. Histological analyses included the examination of alveolar bone underneath the expanders and thickness measurements of the surrounding fibrous capsule. Results: The volume swelling ratio of all STEs did not exceed 5.2. In tensile mode, the highest mean strain was registered for the L group ($98.03{\pm}0.3g/cm$), whereas the lowest mean value was obtained in the S group ($81.3{\pm}0.1g/cm$), which was a statistically significant difference (P<0.05). In addition, the S and L groups were significantly different in terms of tensile strength ($1.5{\pm}0.1g/cm$ for the S group and $2.2{\pm}0.1g/cm$ for the L group, P<0.05). Clinical monitoring showed successful dilatation of the soft tissues without signs of inflammation up to 28 days. The STEs remained volumetrically stable, with a mean diameter in vivo of 6.98 mm, close to the in vitro post-expansion findings (6.69 mm). Significant histological effects included highly vascularized collagen-rich fibrous encapsulation of the STEs, with a mean thickness of $0.67{\pm}0.12mm$. The bone reaction consisted of resorption underneath the STEs, while apposition was observed at their edges. Conclusions: The swelling and mechanical properties of the STEs enabled clinically successful soft tissue expansion. A tissue reaction consisting of fibrous capsule formation and bone loss were the main histological events.
