Disseminated superficial actinic porokeratosis (DSAP) is one of the recently found skin disorderes, which was differentiated from classicaI porokeratosis (Mibelli) and senile keratosis etc. in view of clinical features and hietogenesis by Marvin E. Chernosky on 1967. The one was 60 years old female patient, who had been suffered from multiple dark-brownish keratotic uniform minute papules on dorsa of the hands, forearms and neck with accompanying itching sensation since about 20 year's old of her age. The another one was 38years old housewffe, wha had been suffered from same lesions of the former on the face, neck, extremities especially sun-light exposed area. In both cases, skin lesions were exacerbated during each summer season and increase in numbers of the skin lesions with more severe itching sensation. Chernosky postulated none of a dark-sklnned race affording natural protection against sun-light had skin lesion of D S A P, we were abIe to find out two cases of typical D S A P ih the Korea.

Conjunctivodacryocystorhinostomy(CDCR) with Jones tube is indicated in the cases with upper and lower or common canaliculi obstruction or failed cases of dacryocystorhinostomy. We made a clinical evaluation of the 247 CDCR with Jones tube which had been performed from May of April of 1990. The results were as follows: 1. Canalicular obstruction occured mainly in economic age. 2. The most common cause of the canalicular obstruction was trauma involving canaliculi. 3. The overall success rate of CDCR with Jones tube was 96%. 4. The cases that needed reoperation were extrusion or loss of tube, tilting of tube anteriorly or superiorly, and being buried of Jones tube to nasal cavity in decending order of frequency. 5. Postoperative complications were obstruction of tube with mucoid discharge, granuloma formation, clogging of tube with conjungvtiva, and inflammation around the tube in decending order of frequency. 6. By the development of surgical technique, amount of intraoperative blood loss has been decreased and the duration operation time has become shortened.

Bacteroides fragilis is a Gram negative nonsporulating anaerobic rod bacterium that makes up about 1 to 2% of the norrnal human colonic microflora. In 1984, Myer et al. reported that some strains of B. fragilis produce enterotoxin and cause diarrheal disease in cattle and human. Since then it has been termed enterotoxigenic B. fragilis (ETBF). In this study, we tried to detect enterotoxin gene from 37 B. fragilis strains, isolated in Korean patients, to confirm the existence of ETBF and usefulness of PCR as a rapid diagnosis method. By this method, we identified 9 ETBF strains and confirmed their pathogenesis by cytotoxicity test. No significant cross- reactivity with other anaerobes or aerobes was observed. Thus, the PCR method may be considered useful for the sensitive and rapid detection of anaerobic infections. And the entire amplified PCR mixture was ligated into a pT7Blue T-vector and transformed into E. coli. When the nucleotide sequences of cloned PCR products were compared with reported enterotoxin gene, pBF529 inserted DNA sequence was nearly in good agreement with it but pBF570 inserted DNA sequence showed some difference at nucleotide 270-300. A search for nucleotide sequence homologies revealed that pBF529 exhibited 99%, but pBF570 indicated only 90% identity with reported enterotoxin gene. According to these results, it was suggested that ETBF toxin can be differentiated into at least 2 subtypes.
