Acromelanosis progressiva is a peculiar progressive pigmentary disorder characterized by intensely dark and sharply demarcated hyperpigmentation over the dorsa of fingers and toes, and the pigmentation rapidly spread proximally. A 19-year-old female had sharply demarcated symmetric dark aroarn macules on the dorsa of her hands and feet, forearms, lower legs, face and neck. These pigmentations at first appeared at the age of 5 on the dorsa of her fingers and toes, thereafter these pigmertatons spread progressively to the proximal portion of her body. Histologically, a proliferation of mela biocyte at the epidermal-dermal junction was seen, associated with mild hyperkeratosis. She was othervise normal on physical examination and had no family historv of consanguinity.

A polymerase chain reaction (PCR) method for detection of the pathogenic Yersinia pestis from other Yersinia spp. was developed. Five Y. pestis strains, ninety-two other Yersinia species and twenty-four Enterobacteriaceae strains were collected in Korea and from other countries. Oligonucleotide primers were designed from pathogenic gene of antiphagocytic protein capsule gene (fra 1) and plasminogen activator gene (pla). The 428 bp DNA fragment was amplified from five Y. pestis which contained the fra I gene. No product was amplified from other Yersinia species and other strains of the Enterobacteriaceae. The 439 bp DNA fragment was amplified from three K pestis which contained the pla gene. No product was amplified from two Y. pestis, other Yersinia species and other strains of the Enterobacteriaceae. These showed that the designed primers were specific for detection of Y. pestis among other Yersinia species and Enterobacteriaceae strains. Amplification was successful whether the template was derived from purified DNA or from aliquots of boiled bacterial suspension. The detection limits were 100 pg of DNA and 100 colony forming units (CFU) for fra I and 100 pg DNA and 10 CFU for pla, respectively. Our results prove that the PCR method using specific primers for Y. pestis is a rapid and convenient procedure for routine clinical detection and identification of Y. pestis.

Sister chromatid exchanges (SCEs) observed by means of bromodeoxyuridine substitution and fluorescence plus Giemsa (FPG) technique were proposed as a sensitive and quantitative assay for mutagenicity and cytotoxicity in short-term cultures of phytohaemagglutinin (PHA)-stimulated human lymphocytes. Therefore, this study was carried out to investigate the relation between anticancer agents and cytotoxic effects. Chromosomal analysis was performed on metaphase cells that had divided one, two, or three or more times after treatment for SCEs, mitotic indices (MI) and cell cycle kinetics by FPG technique. The results indicate that anticancer agents led to a dose dependent increase in SCE frequency except methotrexate. But, highly inhibited mitotic indices and delayed cell cycle kinetics were observed except for cyclophosphamide. The author suggest that the difference of SCE frequency is due to the differences in the cytotoxic action of anticancer agents, but although the induction of SCEs has a correlation with cell cycle delay, in some cases the induction of SCEs is not always related to cell cycle delay because of different cytotoxic action of anticancer agents.

A nested polymerase chain reaction (PCR) was applied to detect and identify pathogenic Yersinia enterocolitica and Y. pseudotuberculosis. We used photochemical postamplification procedure with 8-methoxypsoralen to control carryover contamination. Using the ail and inv gene, the sensitivity and specificity of DNA amplification by nested PCR was considerably improved. The amplified fragment sizes were 298 bp for the ail gene and 295 bp for the inv gene. Amplification was successful when the template was derived from three sources: purified DNA, aliquots of boiled bacterial suspension and aliquots of lysed bacterial suspension. The detection limits were 10 fg of DNA and 2 * 10 colony forming units (CFU) for Y. enterocolitica and 10 fg DNA and 2 CFU for Y. pseudotuberculosis.

There have been several reports of more than one type of porokeratosis occurring in the same family or the same individual. We hope to support the view of different phenotypic expressions of a common genetic aberration by describing an additional case of porokeratosis of Mibelli on the perianal area and DSAP on the face, forearms occurring in a 45-year-old man.
