Chromomycosis is a chronic localized infection of the cutaneous and subcutaneous tissues and characterized by verrucoid, ulcerated and crusted lesions with sclerotic margins. It histologically show confluent granulomatous nodules containing large giant cells of the foreign body type. The organisms are differ from other yeastform fungi by the characteristic chestnut-brown color and by the septate division. A case of 51 year old woman with chromomycosis at submental area is presented.

Gastritis cystica polyposa(GCP) is a polypoid cystic lesion showing all the histological features of the hyperplastic polyps and the cysts penetrating through the mucularis mucosae. Most reported GCP lesions were developed at gastraenterostomy stomas. It is rare that GCP develops without history of previous gastroenterostomy. In 1990, however, Kim et al reported a GCP presenting as a submucosal tume-like lesion in a 69-year-old man. Recently, we had experienced two consecutive cases of GCP diagnosed by endoscopic polypectomy. The first case was 49-year-old housewife without history of previous gastric surgery. Esophagogastroduodenoscopy(EGD) showed a 2.0x1.5x1.5cm sized lobulated polypoid lesion with a broad stalk on the anterior wall of the distal antrum. The second case was 45-year-old woman without history of previous gastric surgery. EGD revealed a 1.0 x 1.0 x l.0 cm sized polypoid lesion with a pedicle on the greater curvature aspect of the upper body and two duodenal ulcers with pseudodiverticulum formation. These lesions were endoscopically polypectomized and diagnosed as GCP by the histologic examination.

To elucidate the histologic pattern of alcoholic liver disease (ALD) in Korea, liver biopsies from 173 chronic alcoholics with clinical liver diseases were classified according to the pathologic parameters. One hundred and seventeen cases, the sum of 91 of 116 serum HBsAg negative and 26 of 57 HBsAg positive patients, had the histologic evidence of ALD. Fatty change(23.9%), alcoholic fibrosis (AF)(23.1%) and cirrhosis (23.1%), comprised the three major ALDs, and only 8.5% of cases fit the criteria of alcoholic hepatitis. Chronic sclerosing hyaline disease (CSHD), chronic active alcoholic hepatitis (CAAH) and AF, where non-cirrhotic fibrosis is the predominant change, comprised 44.5% of ALD. Both features of ALD and HBV liver disease (HBV-LD) were found in 17 cases that included 8 AF and 7 cirrhosis. These 17 patients tended to consume less alcohol than patients with other types of pure ALD except alcoholic heaptitis. Patients with the serum HBsAg positive ALD (37.4years) were about 8 years younger than those with the serum HBsAg negative ALD (45.1years). More or less fatty change and foamy degeneration were seen in 77.4% and 31.6% of ALD respectively. Mallory bodies, megamitochondria, iron deposition and perihepatocellular fibrosis were found in 20.5%, 29.9%, 42.7% and 77.8%, respectively. These findings indicate that non-cirrhotic chronic ALD such as CSHD, CAAH and AF are the important histologic patterns of ALD in Korea, and that chronic alcohol consumption and HBV may act synergistically in developing liver disease.

This study is aimed to elucidate the biological nature of the precancerous lesions and to evaluate whether the ethanol alters 3'-Methyl-4-dimethylaminoazobenzene (3'-Me-DAB) induced experimental hepatocarcinogenesis. A total of 108 Sprague-Dawley male rats were used for the experiment and divided into 6 groups according to 3'-Me-DAB and ethanol administration. Administration of the drugs were carried out daily by nasogastric tube insertion and the animals were sacrificed at different interval. A part of right lateral lobe was prepared for the histological examination. Cell kinetics of the immunohistochemical method for bromodeoxyuridine (BrdU). The administration of 3'-Me-DAB induced oval cell proliferation, hyperplastic nodule, cholangiofibrosis and carcinoma in the liver. The mean labelling indices, the percentages of BrdU labelled cells, of hepatocytes were increased by administration of 3'-Me-DAB, only to reverse after cessation of the drug (2.58 vs 0.61). The labelling indices of the oval cells were also affected by the administration and cessation of 3'-Me-DAB (11.41 vs 4.48). In contrast, the cholangiofibrosis did not decrease but were still increasing following cessation of 3'-Me-DAB administration (4.37 vs 5.17 and 8.25 vs 11.29). These finding that the hyperplastic nodule and particularly the cholangiofibrosis have an autonomous proliferative potential and are definite precancerous lesions in the experimental hepatocarcinogenesis. Short term administration of ethanol decreased the incidence of development of the precancerous lesions, but did not affect the labelling indices in all the pathologic lesions of hepatocarcinogenesis.

The post-cataract astigmatism was evaluated clinically between the groups with loose and tight suture in 47 patients(48 eyes) who had taken intraocular lens implantation with extracapsular cataract extraction. The results were as follows; 1. The post-cataract astigmatism in the tight suture group was significantly larger than the loose suture group in the early postoperative period. 2. There was no significant difference of the degree of astigmatism between the groups with loose and tight suture at postoperative 8th week. 3. Postoperative astigmatism was smaller than preoperative astigmatism in both groups at postoperative 8th week. 4. Decreasing velocity of with the rule astigmatism after operation is similar in both groups. Changing time of astigmatism axis: Tight suture group; 6th-8th week. Loose suture group; 3rd-4th week.

In 1980 Liebennan reported that elevated levels of serum angiotensin converting enzyme(ACE) were associated with diabetes mellitus and strongly correlated with the presence of severe retinopathy. Other investigators also suggested that the increased levels of serum ACE might be associated with a widespread microvascular damage. Therefore, the severer diabetic retinopathy can be anticipated the higher serum ACE level. In order to study the relationship between serum ACE levels and severity of diabetic retinopahty, we divided 44 diabetic patients into 4 patients without retinopathy. 21 patients with background retinopathy, 8 patients with preprolifearvie retinopathy, and 11 patients with proliferative retinopathy according to the advancement of retinopathy. The results were as follows: 1. Serum ACE levels of diabetes mellitus patients showed significantly higher than that of nondiabetic controls(21.8 +/- 12.89 vs 14.3 +/- 4.25 U/mL, p<0.05). 2. Serum ACE levels of presence of retinopathy showed significantly higher than that of no retinopathy(23.0 +/- 12.76 vs, 9.7 +/- 7.02 U/mL, p<0.05). 3. Serum ACE levels were significantly elevated in order of preproliferative, background, and no retinopathy(30.3 +/- 17.18, 19.4 +/- 8.75, 9.7 +/- 7.02 U/mL, p<0.05), but serum ACE levels of proliferative retinopathy were not higher than that of background and preproliferative retinopathy. 4. Serum ACE levels were not offectd by age, sex, type of control, required insulin dose and blood sugar level.

OBJECTIVE: Increasingly it is being recognized that genetic factors play a significant role in causing malformation. There are many available prenatal diagnostic methods including cytogenetic karyotyping using amniocentesis and cordocentesis, fluorescence in situ hybridization(FISH), and primed in situ labelling(PRINS). Our purpose was to attempt to discuss the clinical use of cytogenetic karyotyping, FISH, and PRINS. METHODS: We conducted 222 cases of cytogenetic karyotyping using amniocentesis and cordocentesis, l0 cases of FISH, and 10 cases of PRINS from January 1996 to July 1998 at Ewha Womans University Mokdong Hospital. Age distribution, chromosomal abnormalities by age group, indication, karyotype, and baby outcomes were performed. RESULTS: Overall incidence of chromosomal abnormalities was 7.7%(17cases) and chromosomal abnormalities were most frequently noted in 30-34 year old women and 35-39 year old women(2.3%, respectively). Among 222 cases, 25-29 year old women were highest(30.2%). Chromosomal abnormalities among cytogenetic karyotyping cases were Down syndrome, Edward syndrome, Patau syndrome, Deletion(8), Inversion(9), etc. The 5 cases of healthy baby among chromosomal abnormalities were delevered. Among 213 cases of karyotyping using amniocentesis, abnormal karyotyping cases were 15 cases. Among 15 cases, 8 cases were terminated and 5 cases of healthy baby were delivered. Among 9 cases of karyotyping using cordocentesis, 2 cases of chromosomal abnormalities(Edward, Down syndrome) were found and 3 cases healthy baby were delivered. Among 10 cases of FISH results, 6 case of FISH results were the same with G-banding and were different from G-banding. Among 10 cases of PRINS results, we got the PRINS results from 7 cases. CONCLUSION: It is concluded that cytogenetic karyotyping, FISH, and PRINS are very useful to detect chromosomal abnormalities.

To make an accurate diagnosis of esophageal rupture during balloon dilatation without the help of esophagograph, an infusion pump, a pressure transducer and a radiopaque esophageal balloon were connected through a three-way connector. The pressure transducer was connected consecutively to an amplifier, a differentiator and a speaker to detect a pressure drop in the esophageal balloon. Under fluoroscopic monitoring, a radiopaque balloon catheter was inserted in the mid-thoracic esophagus of 30 rabbits and inflated with air until the esophagus was ruptured. A pressure drop in the balloon at the time of esophageal rupture was not only recorded graphically, but also was identified through a speaker. To examine esophageal rupture grossly, the rabbits were sacrificed after esophagography. We could detect the time of esophageal rupture during balloon dilatation in all rabbits accurately by observing the pressure drop on the pressure recorder and by hearing the sound made on a speaker. In 8 patients with esophageal stricture, a deflated radiopaque balloon catheter was inserted to the position inside the narrowing point and inflated by injecting air until the 'hourglass' deformity created by the stricture disappeared from the balloon contour which the pressure change in the balloon was monitored with a pressure recorder. The balloon pressures at the time of disappearance of the "hourglass" deformity from the balloon contour ranged from 200 mmHg to 2000 mmHg in 8 patients with esophageal strictures. Esophageal ruptured did not occur in these patients. In conclusion, our results indicate that this new method is not only safe but promising for patients in the future with esophageal strictures. First, it would reduce the chance of mediastinitis in patients of esophageal rupture. Second, esophageal balloon dilatation can be performed more effectively and safely. Third, it is cost-effective. Forth, radiation esposure to the patient can be reduced.
