Fanconi anemia (FA) is an autosomal recessive disorder of progressive bone marrow failure in patients with congenital malformations. FA is different from acquired aplastic anemia (AA) in terms of the natural course and treatment options. As the frequency of FA is unknown in Korea, we conducted screening tests using DNA clastogenic agents, diepoxybutane (DEB) and mitomicin C (MMC) in southwestern Korea. Forty-three children with AA or other bone marrow failure syndromes and siblings of known FA were evaluated. Six patients with AA (6/24=25.0%) and a 2-month-old patient with myelodysplastic syndrome were found to have increased chromosomal breakage to both DEB and MMC, confirming the diagnosis of FA. No overlap in chromosomal breakage to both agents was found between the FA group and non-FA group. The frequency of FA in this study, much higher than those of previous studies in Korea which did not incorporate the above tests, was similar to that of other countries. DEB and MMC tests were readily feasible and useful in screening FA in patients with AA as well as other bone marrow failure syndromes. A nation-wide screening and registry for FA should be initiated since FA requires different therapeutic and management options from idiopathic AA.

In this study, we established the physicochemical analysis and growth dynamics of yeast and AAB during alcoholic and acetic acid fermentation of black raspberry by a traditional method. Overall, S. cerevisiae and A. pasteurianus species appeared to dominate the TMBV fermentation. In conclusion, this study demonstrated a suitable fermentation system for TMBV by the static surface method. © 2015 Society of Chemical Industry.

In order to reduce harmful biogenic amines in the traditionally fermented soybean products, five isolates with biogenic amines-degrading property were obtained from 83 traditionally fermented soybean products. The strains were found to reduce biogenic amines including histamine, tyramine, putrescine, and cadaverine by 27 to 92% in the cooked soybean containing 5.3% of each biogenic amine over 10 days of incubation. The morphological and biochemical tests and the phylogenetic relationships based on 16S rRNA gene sequences indicated that the five isolates were most closely related to Bacillus subtilis or B. amyloliquefaciens. The use of selected strains would be a potential control measure in manufacturing traditionally fermented soybean products that are difficult to control biogenic amine levels.
