  • Aldose reductase (AR) has been demonstrated to play important role in the development of the diabetic complications such as diabetic retinopathy, diabetic neuropathy and diabetic nephropathy. To discover novel treatments for diabetic complications from natural sources, 69 Korean herbal medicines have been investigated for inhibitory activities on AR. Among them, 7 herbal medicines, Eleutherococcus sessiliflorus (stems), Artemisia japonica (whole plants), Wisteria floribunda (leaves), Eurya japonica (stems, twigs and leaves, leaves), Ampelopsis brevipedunculata (stems) exhibited a significant inhibitory activity compared with 3,3-tetramethyleneglutaric acid as positive control.

  • Aldose reductase (AR) is the key enzyme of the polyol pathway in the development of the diabetic complications. Sixty seven Chinese herbal medicines have been investigated for inhibitory activities on AR. Among them, 7 herbal medicines, Buddleja crispa (twigs and leaves), Taiwania flousiana (twigs and leaves), Sloanea hemsleyana (fruits), Euphorbia nemetocypha (whole plants), Photinia glomerata (twigs and leaves), Vitex yunnanensis (twigs and leaves) exhibited a significant inhibitory activity against AR. Particularly, S. hemsleyana and V. yunnanensis showed 1.2-4.5 times more potent inhibitory activity than the positive control, 3,3-tetramethyleneglutaric acid (TMG).

  • Collected germplasms of five representative dandelion species (Taraxacum ohwianum, T. platycarpum, T. platypecidum, T. officinale, and T. coreanum) were 104 lines from different habitates in Korea and China. Their genetic diversity was analyzed by genomic fingerprinting method using amplified fragment length polymorphism (AFLP). AFLP results of 6 primer combinations were revealed 1,176 total DNA fragments and 523 polymorphic bands with a 44.4% ratio of polymorphism. On the basis of similarity coefficient analysis by unweight pair group method with arithmetic averages (UPGMA), 104 dandelion germplasm lines were ranged from 0.64 to 0.99 and clustered distinct five group depending on the species. Furthermore, a principal coordinate analysis (PCA) by the application of multi-variate analysis indicated significantly greater differences among species than geographical origins.

  • We attempted to isolate the bacterial strains from the fruiting bodies of Agaricus brazilensis and determined their effects on browning and distortions of mushrooms. No bacterial strains were isolated when the middle of browning regions of A. brazilensis were used. Total 125 bacterial strains were obtained from the surface of browning regions and classified into 17 different genera and 29 species by using MIDI methods. Most common genus were Pseudomonas (26), Yersinia (29), and Cedecea (29). High lytic activity were detected when Pseudomonas strains were tested, while relatively low lytic activity were observed with both Yersinia and Cedecea strains.Therefore, we believed the distortion of mushroom could be the result of bacterial infections. Also, the development of brownish color was detected in large number of A. brazilensis strains only by incubation at 4C, suggesting no specific correlation between bacterial strains and brownish color development. Also, it is considered that the development of brownish color can be the normal changes of A. brazilensis.
