  • The freshwater snail genus Semisulcospora is widespread in Korea, Japan, Taiwan and China (Davis, 1969). Semisulcospira gottschei is becoming a candidate shellfish species for aquaculture in Korea. Although amino and fatty acids composition of S. gottschei has been reported by Sim et al. (1994), no information on nutrient requirements for this species is available. (omitted)

  • Objectives: In this study, the author aimed to evaluate the effect of BuOH fraction(YK) from Cinnamomum loureirii on osteoblast proliferation in murine rat calvarial cells. Methods: The osteoblast separated from murine calvariae was cultivated for 10 days and evaluated the cell function. After the addition of YK on the culture medium, we determined the effect of YK on the cell proliferation, alkaline phosphatase activity, apoptosis of the cultivated osteoblast, protein synthesis and collagen synthesis. Results: YK increased the proliferation of rat calvarial osteoblast. YK increased ALP activity of rat calvarial osteoblast. YK did not change the survival rate of rat calvarial osteoblast. YK increased protein synthesis of rat calvarial osteoblast. YK increased collagen synthesis of rat calvarial osteoblast. Conclusions: This study suggests that YK might improve the osteoporosis resulted from augumentation of osteoblast proliferation.

  • Following the previous report (Part I: For Sea-divers and Hwa-Jeon-Min) authers have conducted another nutrition survey for Buddhists (male and female) in a temple 'Soo Duk Sa' locating in ChungNam province. The following results were obtained: 1. Cereals, green vegetables and potatoes were staple foods for the Buddhists (male and female) and no any animal foods were eaten by them during the survey period. 2. Carbohydrate intake was very high and the calorie derived from it occupied approximately 80% of tatal calorie intaken. 3. All the nutrients except carotene, niacin and iron are low in their amounts of intake. Especially, protein and riboflavin intakes are low. 4. Buddhists are prohibited to eat animal foods. Therefore, nutrition education and guidance are needed for them to supplement the protein and some other problems.

  • A temperate phage was isolated from emetic Bacillus cereus NCTC 11143 by mitomycin C and characterized by transmission electron microscopy and DNA and protein analyses. Whole genome sequencing of Bacillus phage 11143 was performed by GS-FLX. The phage has a dsDNA genome of 39,077 bp and a 35% G+C content. Bioinformatic analysis of the phage genome revealed 49 putative ORFs involved in replication, morphogenesis, DNA packaging, lysogeny, and host lysis. Bacillus phage 11143 could be classified as a member of the Siphoviridae family by morphology and genome structure. Genomic comparisons at the DNA and protein levels revealed homologous genetic modules with patterns and morphogenesis proteins similar to those of other Bacillus phages. Thus, Bacillus phages might have a mosaic genetic relationship.
