  • The efficacy of extracts of oat (Avena sativa L.) bran in loperamide-induced constipation in SD rats was evaluated. The rats were divided into six groups of five rats each. The animals in Group 1 (control) and Group 2 (constipated control) were administered with distilled water orally. Groups 3, 4 and 5 comprised of constipated rats administered 100, 200 and 300 mg/kg body weight per day of extract of oat (Avena sativa L.) bran respectively while Group 6 were constipated rats administered bisacodyl (0.25 mg/kg body weight). Constipation was induced by oral administration of loperamide. The feeding characteristics, body weight, fecal properties were monitored. The results show that oats (Avena sativa L.) bran possesses laxative effects in loperamide-induced constipated rats.

  • A proposal of gene transfer scheme from diploid to hexaploid in oats was described. The main idea of this scheme are (1) use Avena magna which has two genomes partially in common with two genomes of the hexaploid Avena sativa or a common genome and the rest genomes partially commonn, and which lead to more regular pairing between them rather than AABB genome type to get 6x-amphiploid as a bridge between ploidy level. Cross between Avena strigosa and Avena magna is compatible and further give 42% seed set, (2) extract tetraploid derivatives which have in corporated desired genes from Avena strigasa to Avena magna, (3) Synthetic petaploid provide 2n=21 chromosome number in female gametes, which lead to complete pairing or nearly so in progenies with Avena sativa, (4) eventually homozygous lines will be produced by selfing the heterozygous (regarding to$A^{As}$ genome) at final step.

  • Recently, studies about various natural extracts to help control blood glucose has been in progress. Avena sativa is well known to have various physilogical effects. Especially, ${\beta}$-glucan has effect about lowering blood glucose level and prevent cardiovascular dz and adult dz related to obesity. In this study we evaluated the effect of Down and control (BM pharmaceutical) which is consist of commercialized Avena sativa fextracts on blood glucose and cholesterol, 6weeks, randomized, double-blind, placebo-controlled trials. The results show not significantly different in all blood index test group from control group, but in glycated albumin decreased 50.33% for test group, decreased 37.91% for control group, in triglyceride decreased 7.51% for test group, increased 3.98 for control group and we can observed Avena sativa has blood glucose and triglyceride lowering effect in some.

  • This study investigated therapeutic candidates with anti-inflammatory potential among traditional dietary ingredients targeting inflammatory bowel disease (IBD). Both Avena sativa and traditional fermented products, such as Korean soy paste, are popular health foods. We investigated the anti-inflammatory effects of soy paste combined with A. sativa (KDA), compared with soy paste without A. sativa (KD) by evaluating the expression of pro-inflammatory cytokines in lipopolysaccharide-stimulated RAW264.7 mouse macrophages and HT-29 human colon epithelial cells. KDA significantly inhibited the production of nitric oxide (NO) and downregulated the pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α in lipopolysaccharide (LPS)-induced RAW264.7 cells. In another in vitro experiment involving LPS-stimulated HT-29 cells, KDA suppressed the levels of IL-8, which is the chemokine elevated in IBD. In addition, KDA exhibited anti-oxidative properties, such as 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and 2,2'-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical scavenging activity. Our findings revealed that A. sativa combined with soy paste exhibits a synergistic anti-inflammatory and anti-oxidant effect following fermentation. These results suggest that KDA may be used as a potential anti-inflammatory therapy against IBD.

  • The biodegradation of phenol in laboratory-contaminated soil was investigated using the Gram-positive soil bacterium Corynebacterium glutamicum. This study showed that the phenol degradation caused by C. glutamicum was greatly enhanced by the addition of 1% yeast extract. From the toxicity test using Daphnia magna, the soil did not exhibit any hazardous effects after the phenol was removed using C. glutamicum. Additionally, the treatment of the phenol-contaminated soils with C. glutamicum increased various soil amino acid compositions, such as glycine, threonine, isoleucine, alanine, valine, leucine, tyrosine, and phenylalanine. This phenomenon induced an increase in the seed germination rate and the root elongation of Avena sativa (oat). This probably reflects that increased soil amino acid composition due to C. glutamicum treatment strengthens the plant roots. Therefore, the phenol-contaminated soil was effectively converted through increased soil amino acid composition, and additionally, the phenol in the soil environment was biodegraded by C. glutamicum.

  • The effects of varying concentrations and durations of butachlor [N-(bytoxymethyl)-2-chlor-2', 6';-diethylacetanilide] treatment on oat (Avena sativa L.) root cell division were studied. Oats were treated from 0 to 48h with concentration ranging from 1$\times$10-6M to 1$\times$10-3M of butachlor. The highest concentration (1$\times$10-3M) of butachlor caused significant inhibition of cell division after 6h treatment. After 18h treatment, 49% and 66% inhibition of cell division occurred at 1$\times$10-5M and 1$\times$10-4M, respectively, while 16% inhibition of cell division occurred at 1$\times$10-6M concentration at same exposure period. Oat treated with 1$\times$10-5M and 1$\times$10-6M showed 69% and 38% inhibition of cell division after 36h. Increasing herbicide concentration at a specific time increased inhibition of cell division, and increasing the duration of treatment at a specific concentration also increased inhibition of cell division. In most instances the greatest inhibition of cell division occurred between 0 to 18h during 48h treatment. A range of concentration of 1$\times$10-5M to 1$\times$10-3M reduced cell enlargement significantly during 24h incubation period. The 1$\times$10-5M and 1$\times$10-3M caused 34% and 75% inhibition of cell enlargement. It was concluded that butachlor caused the growth inhibition of oats by inhibiting both cell division and cell enlargement.

  • The effects of varying concentrations and durations of ethalfluralin (N-ethyl-N-(2-methyl-2-propenyl)-2, 6-dinitro-4-(trifluoromethyl) bezenmine) treated on oat(Avena sativa L.) cell division, cell enlargement, protein synthesis and histology were studied. After 6hr treatment, all concentrations(1${\times}$10^{-6}M to $1{\times}10^{-3}$) of ethalfluralin arrested completely metaphase in the cell division study. The oat coleoptile inhibition of straight-growth test were used to determine the influence of ethalfluralin on coleoptile growth. A range of all concentrations($1{\times}10^{-8}$M to $1{\times}10^{-3}$M) treatment did affect cell enlagement significantly. The $1{\times}10^{-6}$M to $1{\times}10^{-3}$ M concentrations reduced approximately over 50% cell enlargement. Protein incorporation study showed that all concentrations($1{\times}10^{-6}$M to $1{\times}10^{-3}$M) were not affected in protein synthesis. To investigate histological effects, the oats were treated for 24hr with $1{\times}10^{-7}$M. The longitudinal section cells, in the treated oat root tips were appeared to be enlarged and also showed lacking cytoplasm, multinucleate or abnormal cells compare with untreated roots.
