In acupuncture practice of animals, preanesthetics sometimes are needed. The purpose of this study was to select the ideal chemical restraint at acupuncture for gastric motility. Nine healthy mixed breed dogs weighed 10-21 kg and aged 1-3 years old were used in this study. Two EMG surface electrodes were placed between the seromuscular and the mucosal layer of pylorus. Twenty minutes after feeding normal gastric motility was recorded for 60 minutes using physiograph (Narco-Biosystem). Then preanesthetic treated-gastric motility was observed for 30 minutes. Preanesthetics used were xylazine, diazepam, and acepromazine. Acupuncture needles were inserted to BL-21 (Wei-Yu) acupoint, and then changes of gastric motility were recorded for 60 minutes. The gastric motility following xylazine administration (1 mg/kg, IV) was markedly decreased. BL-21 (Wei-Yu) acupoints stimulation did not alter xylazine-induced depression of gastric motility. The diazepam (1 mg/kg IV) treated-gastric motility was increased mildly 20 minutes after drug administration. BL-21 (Wei-Yu) acupoint stimulation after diazepam administration enhanced gastric motility significantly. The gastric motility following acepromazine (0.3 mg/kg, IM) administration was not changed compared with normal gastric motility. Application of traditional acupuncture at BL-21 (Wei-Yu) significantly increased the gastric motility. Based on these results, acepromazine and diazepam could be acceptable chemical restraints for acupuncture therapy of gastric motility, but xylazine couldn't be.

The authors have intended to measure intrinsic dose distribution by Farmer dosimeter in irregularly shaped fields such as L.M. and T shape models in order to determine dose in homogeneity in those models. We made 2 off-xis points in each model and measured the depth dose at 1.5, 5 and 9cm below surface. The results showed 1~3% dose discrepancy between 2 points. We also measured the depth dose by geometric approximation and computer calculation in those models, and came to the conclusion that computer calculation using Clarkson's principle is simpler and the measurements are closer to the ideal data obtained by the experiment in three models of irregularly shaped fields than those of geometric approximation method.

PURPOSE: Vitamin K deficiency is associated with hemorrhagic disease of the newborn. Late hemorrhagic disease is often intracranial and may be fatal. Many countries recommend vitamin K prophylaxis after birth to prevent this hazard of vitamin K deficiency. Nevertheless, there are still controversies concerning the best way of providing effective prophylaxis. A recent article by Golding and colleagues has questioned the safety of the routine use of intramuscular vitamin K for the newborn. These authors reported a significantly increased rate of childhood cancer in infants who received intramuscular prophylaxis. So we compared the prophylactic effect of intramuscular, oral, and maternal administration of vitamin K on hemorrhagic disease of the newborn. METHODS: A total of 60 newborns, delivered spontaneously vaginally, in the Masan Fatima hospital from March to June, 1996, were enrolled. Neonated with intrapartum anoxia, liver disease or hereditary coagulation factor deficiencies, who received antibiotics were excluded. Mothers receiving any medication known to interferes with vitamin K metabolism(such as antiepileptics, antibiotics and anticonvulsions) were excluded. The newborns were randomly allocated to one of the four groups. A group was not supplied. B group received 1mg of vitamin K1 intramusculary, C group received 2mg of vitamin K1 orally. D group was given 20mg of vitamin K1 orally to their mothers at least 2days(range 2 to 7) before birth. Blood samples were collected from 48hrs to 72hrs after birth. PIVKA-II level was measured by enzyme-linked immunosorbent assay (EITEST-MONOP, Eisai Ltd), using a monospecific monoclonal antibody against PIVKA-II. The results obtained are expressed in arbitrary unit (AU) : 1AU corresponds to 1micro gram of purified prothrombin. (healthy adults have less than 0.13AU/ml). PT, PTT were measured simultaneously. RESULTS: 1) PIVKA-II was detected in 4 of 15 infants in group A, who were not supplied. None was detected in other groups. So PIVKA-II detection rate was significantly decreased in other groups compared with group A(p<0.05). 2) PT(sec) values were 12.74+/-0.91, 12.58+/-0.89, 12.36+/-1.04, 12.16+/-0.90 respectively, and there was no significant difference between groups. 3) PTT(sec) values were 52.41+/-13.26, 38.39+/-10.04, 42.67+/-7.01, 39.77+/-10.48 respectively and there was significant shortening in other groups compared with group A (p<0.05). CONCLUSION: Not only intramuscular administration but oral and maternal administration of vitamin K have prophylactic effect on hemorrhagic disease of the newborn. Prophylactic effect on the late hemorragic disease of the newborn requires further extensive study and evaluation.

Radiation therapy was the treatment of choice for CML in the past, in the form of Sl or radioactive phosphorus. Its use has been replaced to a large extent by various chemotherapeutic agents. Recently Sl in CML has been used, both to relieve painful splenomegaly and to take advantage of an indirect effect of Sl on unirradiated bone marrow. We have treated 15 CML cases who had a huge spleen during chemotherapy or even after chemotherapy by 6 MV linear accelerator during the past two years at the Division of Radiation Therapy, Kang Nam St. Mar's Hospital, Catholic College. Response to Sl has been rated according to the scoring system of Roger W. Byhardt, et al. which evaluated the splenic and hematologic response as well as the response of disease-elated systems. According to this scoring system, most patients demonstrated a significant relief of splenomegaly along with improvement of hemogram. And we observed the change of Karnofsky Performance Status after Sl, and survival after a confirmative diagnosis and Sl.

Adult polycystic liver disease (APLD) is an inherited, benign rare condition, often associated with polycystic kidney disease. Liver failure is unusual, but some patients may require therapy. Surgery appears to be more effective in relieving the symptoms of APLD for an extended period than nonsurgical therapies. We report on the successful surgical treatment of a case of APLD located in the left lobe of the liver.

Angiomyolipoma is a benign renal tumor composed of thick- walled blood vessels, smooth muscle cells, and adipose tissue. Despite the aggressive biological and histological features associated with angiomyolipoma, the lack of distant metastasis led us to conclude that angiomyolipoma is a benign neoplasm. Epithelioid angiomyolipoma is a recently described variant type of angiomyolipoma of the kidney. Diagnosis is usually made by histological method and immunohistochemical staining with HMB-45. Several reports suggested the presence of malignant epithelioid angiomyolipomas showing multiple metastases and local aggressiveness. We report a case of epithelioid angiomyolipoma with multiple metastases. Local recurrence and liver, bone and lung metastases developed 11 months after radical nephrectomy. Right hepatectomy and wedge resection of left lobe of the liver with radiation therapy were done.

Mucoepidermoid carcinoma of the liver is a rare variant of cholangiocarcinoma which contains both mucus-secreting glandular cells and squamous cells mixed in nests. We diagnosed a case of mucoepidermoid carcinoma of the liver in a 69-year-old woman who visited hospital because of fever, chill, right flank pain for one week. On admission, she was not jaundiced. Under a provisional diagnosis of liver abscess, a pigtail catheter was inserted to the abscess cavity. One month after the admission, despite conservative treatment, the abscess cavity remained. For a curative treatment and possible hiden malignancy, right hepatectomy of the liver and excision of partial diaphragm were done. Microscopically, the tumor mass composed of solid and invasive nests of epidermoid and mucin-producing cells with desmoplastic stroma. Alcian blue, Periodic-Acid Schiff (PAS) stainings confirmed the presence of mucin in the cytoplasm of mucus-secreting cells. Electron micrographs showed the presence of tonofilaments and confirmed the squamous nature of the tumor cells. The tumor cells, intrahepatic bile ducts and ductules were consistently reactive with cytokeratin 7. Adjacent nonneoplastic liver cells were negative to cytokeratin 7. In the present case, the tumor was diagnosed as mucoepidermoid carcinoma, which was arisen from the intrahepatic bile duct.

BACKGROUND/AIMS: The diagnosis and treatment of benign hepatic lesions remain controversal. The widespread availability of ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI), and their frequent application in evaluating abdominal pain, has resulted in more frequent discovery of incidental benign hepatic lesions. To address these points, the clinical data of patients with benign hepatic lesions treated with surgical resections at our hospital were reviewed retrospectively. METHODS: We reviewed the clinical records of thirty nine patients with benign hepatic lesions who had undergone hepatic resection from January, 1985 to August, 2002 at Hanyang University Hospital. RESULTS: There were 39 patients, whose mean age was 47.0 years. The ages ranged from 24~74 years. There were 14 male patients and 25 female patients. The ratio of male and female was 1:1.8. Major symptoms were right upper quadrant pain, mass, epigastric pain, and non-specific GI symptoms. 22 cases of anatomical resections (10 right lobectomy, 5 left lobectomy, 7 left lateral segmentectomy) and 17 non anatomical resections were done. There were no postoperative deaths in this series. Fourteen patients (35.9%) developed operative complications. All of them were minor complications. During the mean follow up time, symptomatic relief was achieved in patients out of patients who we could contact with opd follow up or telephone interview. Three patients died of massive pleural effusion 4 years after operation, myocardial infarction 14 months after operation, alcoholic liver cirrhosis and diabetes mellitus 33 months after operation. CONCLUSION: Hepatic resection in patients who had benign hepatic lesions in the liver was safe and effective treatment modality if patients were selected with suitable indications.

BACKGROUND AND OBJECTIVES: The aim of our study was to evaluate postoperative mastoid aeration according to the preoperative middle ear disease and investigate the factors affecting it. SUBJECTS AND METHODS: We retrospectively reviewed the high-resolution computed tomography (CT) scans of temporal bones that were taken 1 year after surgery. The postoperative mastoid aeration was evaluated according to the preoperative diagnosis, and classified into three groups: grade 1 (complete mastoid aeration), an air-filled epitympanum and mastoid cavity; grade 2 (partial mastoid aeration), an air-filled epitympanum and partially aerated mastoid cavity; and grade 3 (absence of mastoid aeration), no air space in the mastoid cavity. RESULTS: The overall mastoid aeration rate was 55.8%, with adhesive otitis media accounting for 21.2%, attic cholesteatoma 53.8%, and chronic otitis media 75.4%. The rates of postoperative mastoid aeration were significantly higher in the chronic otitis media cases and attic cholesteatoma cases than in the adhesive otitis media cases. There were 14 cases requiring revision operations due to the development of a retraction pocket in the tympanic membrane. All of the revised cases had grade 3 postoperative mastoid aeration, and underwent canal wall down mastoidectomies. CONCLUSIONS: The degree of postoperative mastoid aeration is associated with the preoperative middle ear disease. When planning a canal wall up mastoidectomy, the surgeon should contemplate the middle ear disease, because a canal wall down mastoidectomy or mastoid obliteration is recommended if the patient has adhesive otitis media.
