The aqueous bumor makes an important role to maintain intraocular pressure. The production and outflow of aqueous humor controls the intraocular pressure. The accurate understanding of the pathway of aqueous outflow and the rate of outflow is essential to the study of glaucoma. The purpose of this study is to investigate the pathway of aqueous outflow after injection of dye into the anterior chamber, the duration of staining and the degree of delay of aqueous outflow after the use of viscoelastics. Three dyes. Gentian Violet, Methylene Blue and Viscoelastics mixed with Gentian Violer were injected into the anterior chambers of 20 eyes of 10 rabbits. The eyes were enucleated at 1 hour, 2 hour, 3 hour, 4 hour after injection of Gentian Violer and Methylene Blue. After injiection of viscoelastics mixed with Gentian violet, the eyes were enucleated at 2 hour, 4 hour, 6 hour, 8 hour, and 9 hour. The enucleated eyes were performed for frozen section and the fragments were observed by light microscopee. Gentian violet and Merhylene Blue were stained in the pathway of the pectinate ligaments, trabecular meshwork, intrascleral plexus and the pathway of the capillary network of iris and suprachoroidal space. The disappearance of injected dye was ended between 3 hour and 4 hour. And the viscoelastics mixed with dye was removed between 8 hour and 9 hour. This means that viscoelastics make the outflow of aqueous delay.

Melanosis coli is the brownish pigmentation of the colon associted with the ingestion of anthraquinone compounds as iaxatives. The brownish discoloration of the colon mucosa is due to accumulation of macrophage containing lipofuscin pigment in the lamina propria. This is the one of the complications of laxative abuse, but the pigments disappear by withdrawing the anthraquinone. We report a case of malanosis coli histologically confirmed by fibersigmoidoscopic biopsy in a 70-year-old female patient consuming anthraquinone compound for twelve months with a review of the literature.

Recently the use of hydrochloric acid as a toilet disinfectant has become more common, and the risk of its ingestion is though to be increasing. We experienced a case of 67 year-old man who accidentally ingested hydrochloric acid and as a result developed a postprandial epigastric fullness end pain 3 weeks thereafter, The patient underwent an UGI series, fiberoptic gastroscope and abdominal ultrasonography and was found to have a gastric midbody stricture. A total gastreetomy and Roux-en- Y esophagojejunostomy was performed. We report this case with brief review of the literature.

Pseudomyxoma peritonei is a rare disorder chracterized by abdominal distension resulting from the accumulation of a mucinous, gelatinous, translucent material which arises from rupture of pre-existing mucinous cystadenomas and cystadenocarcinomas of the ovary and mucocele of the appendix. We report 11 cases of pseudomyxoma peritonei which were diagnosed by surgical and pathological findings. The results were as follows. 1) The mean age of 11 cases was 51 years and 5 cases were male and 6 cases were female and male to female ratio was 1 to 1.2. 2) Clinical manifestations in 11 cases were abdominal distension in 5 cases (45.5%), palpable mass in 4 cases(36.6%), abdominal pain in 4 cases(36.6%), nausea in 3 cases(27.3%), weight loss in 3 cases(27.3%), diarrhea in 2 cases(18.2%), constipation in 1 case(9.0%), anal bleeding in 1 case(9.0%) and defecation difficulty in 1 case(9.0%). The duration of symptoms was 2 days to 1 year. 3) The primary sites of pseudomyxoma peritonei were ovarian cancer in 3 cases(27.2%), appendiceal cancer in 2 cases(18.2%), gastric cancer in 2 cases(18.2%), rectal cancer in 1 case(9.1%), cecal cancer in 1 case(9.1%) and unknown origin in 2 cases(18.2%). 4) Following surgical interventions were performed; right hemicolectomy in 2 cases, palliative gastrojejunostomy in 2 cases, oophorectomy in 1 case, omentectomy in 1 case and right hemicolectomy with gastrojejunostomy in 1 case. 5) The adjunctive anti-cancer chemotherapy was done in 4 cases(36.4%) by combination of actinomycin D, adriamycin, CCNU, cisplatin, cytoxan and fluorouracil, And chemotherapy only was done in 2 cases and hyperthermia was done in 1 case.

Objective: To assess left ventricular remodeling patterns using cardiac computed tomography (CT) in children with congenital heart disease and correlate these patterns with their clinical course. Materials and Methods: Left ventricular volume and myocardial mass were quantified in 17 children with congenital heart disease who underwent initial and follow-up end-systolic cardiac CT studies with a mean follow-up duration of 8.4 ± 9.7 months. Based on changes in the indexed left ventricular myocardial mass (LVMi) and left ventricular mass-volume ratio (LVMVR), left ventricular remodeling between the two serial cardiac CT examinations was categorized into one of four patterns: pattern 1, increased LVMi and increased LVMVR; pattern 2, decreased LVMi and decreased LVMVR; pattern 3, increased LVMi and decreased LVMVR; and pattern 4, decreased LVMi and increased LVMVR. Left ventricular remodeling patterns were correlated with unfavorable clinical courses. Results: Baseline LVMi and LVMVR were 65.1 ± 37.9 g/m2 and 4.0 ± 3.2 g/mL, respectively. LVMi increased in 10 patients and decreased in seven patients. LVMVR increased in seven patients and decreased in 10 patients. Pattern 1 was observed in seven patients, pattern 2 in seven, and pattern 3 in three patients. Unfavorable events were observed in 29% (2/7) of patients with pattern 1 and 67% (2/3) of patients with pattern 3, but no such events occurred in pattern 2 during the follow-up period (4.4 ± 2.7 years). Conclusion Left ventricular remodeling patterns can be characterized using cardiac CT in children with congenital heart disease and may be used to predict their clinical course.

Peliosis hepatis is characterized by the presence in the liver of blood-filled cavities, which may or may not be lined with sinusoidal cells. The individual cysts or cavities usually do not exceed several centimeters in diameter. The cysts are typically continuous with adjacent, more normal sinusoids, and they sometimes can be seen in continuity with hepatic venous tributaries. The lesion is usually diagnosed by gross or microscopic examination. When suspected, it can be diagnosed by percutaneous liver biopsy. In the past, peliosis hepatis is primarily associated with wasting diseases, such as tuberculosis, malignancy, and chronic suppurative infection. However, recently peliosis hepatis is seen most commonly in association with the administration of anabolic steroids or HIV infection. We report a case of peliosis hepatis that is diagnosed by peritoneoscopic live biopsy and not associated with known disease.

Primary gallbladder cancer is a highly malignant tumor and is characterized by early metastasis and rapid progression of disease. Since the majority of patients have unresectable disease, laparotomy, instead of providing relief of symptoms, often adds to the morbidity and needs to be avoided in patients with advanced disease. Clinical features, peritoneoscopic findings, and comparison of peritoneoscopy with radiologic studies were reviewed in 29 patients, who underwent peritoneoscopy, with primary gallbladder cancer at Severaace Hospital, College of Medicine, Yonsei University between Aug. 1982 and Mar. 1994.

Telbivudine is an L-nucleoside analogue with potent antiviral activity against hepatitis B virus (HBV). Clinical trials have shown that telbivudine has a more potent and sustained antiviral activity with a lower frequency of viral resistance than lamivudine. Although there are several reports concerning the safety profile of telbivudine, most adverse events are described as mild and transient in nature. Here we report two cases of telbivudine-induced myopathy in patients with chronic hepatitis B who were siblings.
