To determine the status of Enterobius vermicularis infection among children living on western and southern coastal islands of the Republic of Korea, children (3-10 years) in 39 kindergartens and primary schools were examined using the cello-tape anal swab method, during July and August 2000. Of 1,661 children examined, 307 (18.5%) were found to be positive for E. vermicularis eggs. The highest infection rate (59.3%) was found in a kindergarten and a branch school of Shinyang primary school on Chujado, Jeju-do (Province). Remarkable differences in egg positive rates were observed in different localities. The egg positive rate for boys (21.3%) was significantly higher than that of girls (15.4%) (P = 0.02). However, positive rates were not significantly dependent on age. The results of the present study show that E. vermicularis infection is highly prevalent among pre-school and primary school children living on the western and southern coastal islands of the Republic of Korea, and indicate the need for efforts to control this infection. 相似文献

Malaysia is fortunate and proud to contain some of the world’s richest biodiversity. In Malaysia, there are an estimated 185,000
species of fauna and 12,500 species of flowering plants, many of which are endemic to tropical forests in this region. Indeed,
such diversity is an important and invaluable national asset to safeguard both present and future generations. In vitro conservation offers possible techniques for the preservation of plant germplasm that at present is difficult to maintain
or is maintained with limited success. Research at the Universiti Kebangsaan Malaysia (The National University of Malaysia)
focuses on the cryopreservation of woody fruit species with seeds that cannot tolerate cryopreservation (recalcitrant or intermediate).
Among the plants with recalcitrant seeds are such traditionally important edible tropical fruits as mangosteen, langsat, and
rambai (Garcinia mangostana, Lansium domesticum, and Baccaurea motleyana). Citrus aurantifolia, Citrus suhuiensis, Citrus madurensis, Citrus hystrix, and Fortunella polyandra are among the Citrus and Citrus-related species studied. Cryopreservation studies include the Nepenthes species (pitcher plants) of Malaysia. Fundamental research on desiccation and low-temperature tolerance and on the physiology
of desiccation are used to understand seed behavior, a prerequisite for the development of successful conservation techniques.
At the same time, cryopreservation protocols for several Citrus and forestry species were developed for embryonic axes and adventitious shoots, mainly using rapid dehydration and PVS2 vitrification
techniques. There are no successful standard techniques or protocols for species with highly recalcitrant seeds such as Garcinia species. Modification of existing protocols or development of new methods is required, but this can be accomplished only
when a detailed understanding of the recalcitrant nature of the seeds or explants is achieved. While we have considerable
knowledge concerning the basics of biochemical processes and some molecular data from work on desiccation-tolerant seeds,
a great need remains for understanding the cause of the recalcitrance or desiccation sensitivity of these seeds. It may be
necessary to use a systems biology approach that exploits the “omics” technologies to generate global molecular data. In combination
with bioinformatics for data integration and analyses, this approach would move toward improved modeling of the biological
pathways associated with the development of recalcitrant seeds. 相似文献

Blomia tropicalis allergens are the most important mite allergens in tropical regions. Most of them only have 30-40% sequence identity with their Dermatophagoides counterparts and they share low IgE cross reactivity and exhibit different immunobiology. Unlike the pyroglyphid counterparts, Blo t 5 is the major allergen whereas Blo t 1 only has modest allergenicity. 相似文献
