Purpose: The prognosis for gastric cancer with peritoneal seeding is very poor, and the role of surgical intervention is limited. We evaluated the effect of radical removal of primary and metastatic lesions on survival in gastric cancer with peritoneal seeding. Materials and Methods: From May 1989 to March 1999 at Kosin University Gospel Hospital, 115 patients revealed gastric cancer with peritoneal seeding but without liver or lung metastasis and without follow-up loss. The study group included 86 patients who underwent surgery for radical removal of primary gastric and metastatic peritoneal lesions. The control group included 29 patients who experienced incomplete removal of primary or metastatic lesions. Both groups received intraoperative intraperitoneal chemotherapy using mytomycin or cisplatin, and 25 patients underwent postoperative intravenous chemotherapy. Results: The median survival times in the study and the control groups were 13 months and 4 months, respectively (p<0.0001). The 1-year, 2-year, and 5-year survival rates were, respectively, $50.6\%,\;18.1\%$, and $11.3\%$ in the study group and $14.8\%,\;3.7\%$ and $0\%$ in the control group (p<0.0001). In the study group, neither postoperative intravenous chemotherapy nor microscopic invasion of the resection margin had any effect on survival, but intraoperative intraperitoneal chemotherapy and degree of peri-toneal seeding, especially the amount of peritoneal seeding, had an effect on survival. In the control group, neither intraperitoneal nor intravenous chemotherapy had any effect on survival, but resection of the primary gastric lesion improved survival. Conclusion: Radical removal of primary gastric and metastatic peritoneal lesions improved the survival rate for gastric cancer with peritoneal seeding. However, a randomized prospective study is needed to correctly evaluate the effect of intraperitoneal or intravenous chemotherapy.

A 61-year-old male who complained of right upper quadrant pain was referred to the authors for evaluation after his computed tomography suggested biliary adenocarcinoma. The lesion consisted of multiple cysts with papillary mass and peri-ampullay mass. The patient underwent an operation due to a clinical suspicion of biliary cystadenocarcinoma, but the pathology confirmed biliary papillomatosis (BP) after diagnosing intrahepatic papillary neoplasm with high-grade dysplasia and invasive adenocarcinoma with papillary neoplasm from the distal common bile duct to the duodenum. BP is a disease characterized by multiple papillary masses. Its cause has yet to be discovered. It commonly manifests as bile duct dilation but rarely as a ductal cystic change. Under computed tomography or magnetic resonance imaging, both the BP and the cystic neoplasm can show bile duct dilation and a papillary mass, which makes their differential diagnosis difficult. A confirmative diagnosis can be made through a pathologic examination. BP is classified as a benign disease that can become malignant and may recur, though rarely. Its treatment of choice is surgical resection. Laser ablation or photodynamic therapy can be used for unresectable lesions. In the case featured in this paper, biliary papillomatosis was difficult to differentiate from cystic adenocarcinoma due to diffusely scattered multiple large cystic lesions in the liver, and it was histologically confirmed to have become malignant with cystic duct dilation after the operation. This case is reported herein with a literature review.

The ability of $^{67}Ga$, administered carrier free as the citrate complex, to localize in human and animal tumors to an extent sufficient to permit visualization of the lesion by scanning is well established. However, neither the mechanism of $^{67}Ga$ uptake by tumors or inflammatory cells nor its relationship to cell type or to the biochemical status of the cell is yet understood. Author investigated the uptake of $^{67}Ga-citrate$ using subcellular tissue fractionation of rat livers treated with $CCl_4$ associated with the $^3H-thymidine$ incorporation rate to detect subcellular localization of $^{67}Ga$ and it's relationship in DNA synthesis. Large amounts of $^{67}Ga$ associated with the soluble portion of tissue homogenate rather than with isolated cell organelles and not related nuclei residue in the regenerating period after hepatocellular injury caused by $CCl_4$. The elevated uptake of $^{67}Ga$ in the livers of $CCl_4$ treated rats was also inhibited when protein synthesis was stopped by cyclohexamide. Thus protein and the soluble portion of issue homogenates seems to play an important role in the elevated uptake of $^{67}Ga$ in liver injury induced by $CCl_4$ treated rats.

We experienced a case of herpes zoster in a 9-months aged infant as followings; The patient had no history of chickenpox or varicella vaccination. Also, her mother had no history of varicella infection and no contact history with varicella during pregnancy. The patient had only a history of exposure to chickenpox patient at 7th days after birth, but fortunately chickenpox was not developed. Sequentially, symptoms of cough with fever and tachypnea were developed on admission date(7 days had passed already after development of the initial skin lesion). On physical examination, multiple grouped painless erythematous papulovesicles with small crusts were observed on the right lower back, flank and abdomen along the T11 dermatome. Coarse breathing sound was osculated, and increased linear infiltrations on both parahilar areas were seen on chest radiography. Liver enzymes were slightly elevated. Tzanck test was negative. The initial titers of anti-VZV IgM and IgG on admission were negative, but the following titers of anti-VZV IgM and IgG were positive. The patient received treatment of acyclovir for 7 days, and healed completely without sequelae. We report this case with brief review of related literatures.

A 10 months old, male Poongsan dog was referred with a history of right forelimb lameness due to hit by a car a few hours before presentation. On the physical examination, the dog showed pale mucous membrane, respiration distress, and skin abrasions. The main laboratory finding was leukocytosis, while hematocrit was normal. Abdominal radiography revealed the loss of abdominal serosal detail, which was diagnosed as peritoneal hemorrhage on ultrasonography (US) and aspiration. On computed tomography (CT), hepatic and splenic injuries were seen characterized by the discontinuity of the capsule with irregular margin and lower density lesions than parenchyma. No contrast enhancing area were shown in the laceration lesion. The accessory spleen was incidentally found by US and CT. In this case, acute intra-abdominal hemorrhage from splenic and hepatic laceration was diagnosed using CT.

Duck viral hepatitis is an acute, highly infectious viral disease of young dacklings aged from two days to three weeks. The significant lesion associated with the disease was enlarged liver including necrotic foci and numerous hemorrhagic spots. We have isolated five strains of duck hepatitis virus (DHV) from field cases showing about 20% mortality with a sign of opisthotonos. When a-day-old ducklings were intramuscularly inoculated with one of the isolates, 92% of the birds were died within 5 days. We attempted to develop an attenuated strain of duck hepatitis virus (DHV) using one of the isolates by serial chicken embryo passages. The propagation of DHV in chicken embryos was carried 140 passages. The virus titer increased gradually from the $21^{st}$ through the $50^{th}$ passage, but there was no significant increase of virus titer in subsequent passages after then. Through the serial passages, the virulence of the virus for chicken embryos was gradually increased but decreased for ducklings. The pathogenicity of the virus for ducklings was preserved up to the $21^{st}$ passage but disappeared at the $50^{th}$passage. An attenuated Korean isolate which was passaged 140 times in chicken embryos gave good protection in ducklings against both challenge infection to a Korean virulent strain and to a DHV-DRL strain, a type 1 reference strain of DHV, which indicated that the Korean isolates could be classified as DHV type 1. And the above results suggest that an attenuated Korean isolate can be used for developing a live DHV vaccine.

This study was performed to compare DNA content by flow cytometer (FCM) and glutathione S-transferase placental form (GST-P) positive foci for searching objective and accurated properties of tumor. Sprague-Dawley rats aged six weeks were divided into three groups and group 1 and 2 of rats were given an intraperitoneal injection of diethylnitrosamine at 200mg/kg body weight and group 3 of rats were given saline. Three weeks after beginning of the experiment, all groups were performed partial hepatectomy. Group 1 of rats were begun to feed on diets containing 0.02% 2-acetylaminofluorene as a promoter for six weeks, group 2 and 3 of rats were begun to feed on basal diets. At 4, 6, and 8 weeks after initiation, all groups of rats were killed, livers were extracted for H & E stain, immunohistochemical stain, and DNA ploidy analysis. In quantitative analysis for GST-P positive lesion number and area by using Image Analyzer, group 1 and 2 represented significant difference in comparison with group 3. In ploidy distribution, diploid cells of group 1 and 2 were increased significantly in comparison with those of group 3 at 4, 6, and 8 weeks after initiation, respectively tetraploid cells were reduced. But S-phase cells were not changed significantly. It is concluded that ploidy change by FCM is useful as objective data for early detection in hepatocarcinogenesis. Therefore, methodology and study of DNA content are carried out for more objective and accurate ploidy analysis in liver tumor.

We report an extremely rare case of primary squamous cell carcinoma of the stomach. A 69-year-old man was admitted to our hospital with a 2-month history of dysphagia and tarry stools. Endoscopic examination revealed a cauliflower-shaped protruding mass along the lesser curvature of the gastric cardia. Biopsy of the lesion revealed squamous cell carcinoma of the stomach. Computed tomography revealed a thickened stomach wall and a mass protruding into the gastric lumen. Total gastrectomy with splenectomy, distal pancreatectomy, and Roux-en-Y reconstruction was performed, together with a lower thoracic esophagectomy via a left thoracotomy. Histopathological examination of the specimen revealed well-differentiated squamous cell carcinoma of the stomach. Postoperative follow-up was uneventful for the first 18 months. However, multiple liver metastases and para-aortic lymph node metastasis developed subsequently. Despite systemic combination chemotherapy, the patient died because of progression of the recurrent tumors. Here, we review the characteristics of 56 cases of gastric squamous cell carcinoma reported in Japan.

A 10-year-old, intact male, toy poodle was presented with abdominal distension, truncal alopecia, hepatomegaly, and sustained elevation of alkaline phosphatase. Vacuolar hepatopathy and glycogen deposition in hepatocytes were confirmed by liver biopsy and ultrasound-guided fine-needle aspiration with periodic acid-Schiff (PAS) staining of mass lesion respectively. Cortisol and some sex hormones associated with adrenal gland were analyzed at IDEXX Reference Laboratories before and 1 hour after ACTH stimulation. The results of analysis confirmed elevation of some sex hormones including androstenedione, progesterone and 17 hydroxyprogesterone, not cortisol concentration, before and 1 hour after ACTH stimulation. The dog was diagnosed as atypical form of hyperadrenocorticism associated with sex steroids excess. The treatment was initiated with trilostane (0.5 mg/kg, PO, q12hr) that is an adrenal steroid synthesis inhibitor. Trilostane was administered for 8 weeks and the clinical sign including truncal alopecia was improved.

I reached following conclusion through a bibliographic study about the drug dependence. 1. The drug dependence is the case that taking drugs continually in order to get around discomfort and get mental drug efficacy. that is also the state of poisoning that shows compulsions that using all means to get drugs. the drug dependence is coincident with alcolism in Oriental Medicine. 2 Medicinal matters that causes the drug dependence consist of two field. one is licit drugs, including a tranquilizer, a sleeping pill, anti-anxiety drug, alcohol, caffeine, tobacco, etc. the other is illict drugs, including opium products, psychostimulant, a hallucinogen, aromatic agent(adhesives, LSD, etc.) 3. Drugs that causes dependences has the habit which causing mental dependences and the medicinal poisining which causing physical dependences. 4. A syndrome of abstain from the drug which rides on all kinds of drugs is analogous to depressive psychosis, epilepsy, insanity, depressive syndromes, disorder of internal organs, histery, dizziness, etc. 5. The drug dependence causes visceral dysfunction, that is chiefly inflammatory lesion of brain, heart lung etc. (inflammatory lesions os mainly due to infect.) and injuries liver which removes toxic agents and kidney which is an excretory organ. 6. The treatment of the drug dependence, which needs at first check the medical record and the syndrome, is consist of the expectant treatment and isolating treatment as a rule and sometimes mental therapeutics is going on at the same time. 7. The oriental medical cure of the drug dependence needs more concrete study.
