Telomerase is an RNA-dependent DNA polymerase that synthesizes TTAGGG telomeric DNA onto chromosomal ends to compensate for sequence loss during replication. It has been detected in a variety of human malignancies, suggesting that such activity may play a role in the tumorigenic process. To determine whether telomerase is reactivated in malignant fibrous histiocytoma, 12 tissue samples with this tumor were analyzed for the telomerase activity by a radioactive PCR-based TRAP (telomeric repeat amplification protocol) assay. All of the tumors were further investigated for the expression of human telomerase RNA (hTR) by an in situ hybridization (ISH). Telomerase activity was detected in one (8.3%) sample. Expression of hTR was demonstrated in 7 (58.3%): one telomerase-positive and six telomerase-negatives. These data indicate that the reactivation of telomerase is an uncommon event and not an important factor involved in tumorigenesis in malignant fibrous histiocytoma. It is noteworthy that 50% of the patients with grade 2 tumors expressed hTR, suggesting that telomerase RNA may be useful as a marker for identifying tumor aggressiveness earlier than the conventional histopathologic grading scale.

We performed 75 cases of daryocystorhinostomy from Jan. 1988 to Dec. 1990. A routine dacryocystography was performed prior to operation in all cases. A modified T oti's method was applied as a surgical technique "H" shaped incision was done. Both anterior and posterior flaps were sutured adequately and vaseline guaze was used as a plugging agent for 7 to 10 days Success was achieved in 72(96.0%) of 75 cases. The causes of 3-failures were organized granulation tissue and trauma.

Sebaceous carcinoma is an uncommon neoplasm usually associated with ocular adnexa. This malignancy may occur at any anatomic site that contains sebaceous glands. Despite the widespread anatomic distribution of sebaceous glands, extraocular sebaceous carcinoma occurs with far less frequency. We report a case of an 87-year-old Korean woman with extraocular sebaceous carcinoma treated with total excision.

PURPOSE: We performed this study to evaluate the changes of gallbladder ejection fraction (GBEF) in diabetic patients with or without autonomic neuropathy. MATERIALS AND METHODS: This study included 37 diabetic patients (25 women, 12 men, mean age 51 years) and 24 normal controls (10 women, 14 men, mean age 38 years). After intravenous injection of 185 MBq of 99mTc-DISIDA, serial anterior abdominal images were acquired before and after fatty meal. Regions of interest were applied on gallbladder and right hepatic lobe on 60 and 90 minute images to calculate GBEF. RESULTS: GBEF was significantly reduced in diabetes with autonomic neuropathy (43+/-12.3%) and without autonomic neuropathy (57.5+/-13.2%) compared with normal controls (68+/-11.6%, p <0.05). And also, GBEF was significantly reduced in diabetes with autonomic neuropathy compared with diabetes without autonomic neuropathy (p <0.05). Fasting blood glucose level, age, sex, hemoglobin A1c, body mass index, serum lipid level were not different in these two diabetic patient groups (p>0.05). When 50.2% of GBEF was used as the criteria for diabetic autonomic neuropathy, the sensitivity and specificity were 80%, 76.5%, respectively. The area under receiver operating characteristic curve was 0.846. CONCLUSION: GBEF of diabetic patients with autonomic neuropathy was significantly reduced than that of diabetic patients without autonomic neuropathy.

We have experienced a case of occult hepatocellular carcinoma metastasized to the heart in a 41 year old female. The hepatocellular carcinoma invaded the hepatic vein, grew in a snakelike fashion up the inferior vena cava and reached the right atrium. Ultrastural examination in this case confirmed the hepatocellular origin of the tumor.
