  • Genetic variation among the base isolates and monosporidial strains derived from these isolates of Tilletia indica- the causal agent of Karnal bunt (KB) in wheat, was analyzed by morphological, growth behaviors and RAPD-ISSR based molecular polymorphism. Genetic make up of fungal cultures vary among each other. The magnitude of variation in KBPN group is less (narrow genetic base) when compared to the other groups KB3, KB9 and JK (broad genetic base) reflecting that variability is a genetically governed process. The generation of new variation with different growth characteristics is not a generalized feature and is totally dependant on the original genetic make-up of the base isolate generating new monosporidial strains. Thus, it can be concluded that monosporidial strains derived from mono-teliosporic isolate, consists of genetically heterogeneous population. The morphological and genetic variability further suggests that the variation in T. indica strains is predominantly derived through the genetic rearrangements through para sexual means.

  • With a view to improving the method of rice marketing quality estimation, vaietal milling characteristics and apparent qualities were studied and their statistical interrelationships were computed for 2 years crops, using 22 varieties of Japonica type and Japonica x Indica type (Tongil). The milling yield was the highest for Japonica, while the broken rice yields was the highest for Japa.xInd. type. But bran yield did not show any significant differences among rice types. Milling factors were volume weight of brown rice, dehulling yield, and Polishing yields; the better these factors, the higher the yield. High apparent quality milled rice with high milling yield were produced from rice types whose broken rice, chalked rice, husk yield and bran yield were little and/or low.

  • This research studied the effects of Backryeoncho (Opuntia ficus-indica var. saboten) extract as an additive in kimchi in various amounts (0%, 0.4%, 0.8%, 1.2%), and its acceptance by middle school students in the Jeonju area. The treated kimchi had a higher pH than the untreated kimchi without extract, and the titratable acidity of the kimchi decreased with the addition of the Backryeoncho extract. The degree of salinity decreased in kimchi with the added Backryeoncho extract in a dose-dependent manner. The cutting force and compression force were higher in kimchi where the extract was added during the fermentation period resulting in improved texture of the kimchi. The addition of the extract slowed growth of total bacteria (1.83~2.12 log CFU/mL) and lactic acid bacteria (1.4 log CFU/mL) as compared with the control sample. In the sensory evaluation of overall taste, kimchi with 0.8% extract added demonstrated higher evaluation in overall categories. The acceptability of Backryeoncho extract as an additive in kimchi among middle school students was higher than in the control sample, with an optimum additive of 0.4% extract, based on the lowest volume of leftovers.

  • Injeolmi is a kind of rice cake made from glutionusrice grains by steaming and pounding much into dough. The way of making Injeolmis has an important effect on the characteristics of Injeolmis; whether the glutinous rice is Japonica or Japonica/Indica, and whether it is steamed in rice grain, or in rice powder. The characteristics of Injeolmi were investigated through sensory evaluation and Instron Universal testing machine. The results were as follows; 1. Injeolmi which was steamed in glutinous rice was more chewier than powder Injeolmi after 48 hours. 2. In the case of changing ${\beta}$-starch to ${\alpha}$-starch by reheating. Injeolmi with microwave oven, the result was same as above investigation in color, appearance, and chewiness. But in hardness grain Injeolmi became tenderer. 3. Instron measurement of texture indicated that there were significant differences in hardness. This result was the same as that by the sensory evaluation. 4. The preference for Injeolmi was increased when it was made of high moisture contented glutinous rice. japonica had more moisture than J/Indica.

  • Opuntia ficus-indca(Op) extract has been claimed to have several therapeutic properties in oriental medicine including anti-inflammatory and anti-rheumatoid arthritis effects. Little is known of its effect on the activation of immune cells such as T cells and macrophages. To evaluate the functional effect of Op extract on immune cells, we examined whether Op extract stimulates the proliferation of T cells and the secretion of cytokines including IL-1 beta, IL-6 and tumor necrosis factor-alpha in THP-1 cell lines by RT-PCR. Op extract significantly enhanced the proliferation of T cell clone(D10S). Transcription of cytokines including IL-1 beta, IL-6, and TNF-alpha peaked 6 hrs after exposure to Op extract(100g/ml) in the THP-1 cell line and declined and declined thereafter. In an experiment to test the dose dependency of transcription of cytokines, transcription increased at a dose of 10 g/ml and the maximum expression was obtained at 100 g/ml, 6 hrs after exposure to Op extract. These findings suggest that Op extract is a potent stimulant of immune cells including T cells and macrophages, which acts by stimulating T cell proliferation and upregulating cytokines. These phenomena imply that some edible plants may be beneficial to living animals through the activation of immune functions.

  • Hydration rate of 35 Japonica and 24 J x Indica rice varieties at $23^{\circ}C$ was investigated and an attempt was made for a tentative classification of milled rice into six groups based on hydration rate. Each rice variety had characteristic value for hydration rate. In general, J x Indica rice hydrated at a faster rate than Japonica rice. Hydration rate was negatively correlated with the ratio of length to width of rice grain. No correlation was found between hydration rate and protein, amylose, surface area, volume or initial water grain.

  • The purpose of this study was to investigate the antioxidant and anti-inflammatory activities of hot water (AMPW) and 70% ethanol (AMPE) extracts of apple mango (Mangifera indica L.) peel. The antioxidant activities were measured using a total polyphenol, electron-donating, 2,2'-azinobis [3-ethylbenzothiazoline6-sulfonic acid] (ABTS) radical scavenging assay. The total polyphenol content of AMPW and AMPE was 66.08 ± 0.62 mg TAE/100 g and 100.13 ± 0.23 mg TAE/100 g, respectively. As a result of measuring the electrondonating ability, at a concentration of 1,000 ㎍/ml, AMPW and AMPE showed an effectiveness of 86% and 94%, respectively. The ABTS assay showed 80% and 98% respective radical scavenging activity for AMPW and AMPE, at a concentration of 1,000 ㎍/ml. The cell viability on macrophage cells was performed using a 3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyl-tetrazoliumbromide (MTT) assay, and the results showed more than 90% cell viability at a 100 ㎍/ml concentration. Anti-inflammatory activity was verified by confirming nitric oxide (NO) production inhibitory activity, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) protein and mRNA expression inhibitory activity from lipopolysaccharide (LPS)-treated RAW 264.7 cells. The NO production inhibitory effects were measured using the Griess assay, which confirmed 45% and 40% inhibition after treatment with AMPW and AMPE, respectively. Moreover, the protein and mRNA expression of inflammatory-related factors iNOS and COX-2, decreased in a concentrationdependent manner. In conclusion, this study showed antioxidant and anti-inflammatory effects of Mangifera indica L. peel and revealed its promising potential for application as an antioxidant and anti-inflammatory agent.

  • This study quantified, through a direct harvesting method, storage and annual uptake of carbon from open-grown trees for three landscape tree species frequently planted in the southern region of Korea, and developed quantitative models to easily estimate the carbon reduction by tree growth for each species. The tree species for the study included Camellia japonica, Lagerstroemia indica, and Quercus myrsinaefolia, for which no information on carbon storage and uptake was available. Ten tree individuals for each species (a total of 30 individuals) were sampled considering various stem diameter sizes at given intervals. The study measured biomass for each part of the sample trees to quantify the total carbon storage per tree. Annual carbon uptake per tree was computed by analyzing the radial growth rates of the stem samples at breast height or ground level. Quantitative models were developed using stem diameter as an independent variable to easily calculate storage and annual uptake of carbon per tree for study species. All the quantitative models showed high fitness with $r^2$ values of 0.94-0.98. The storage and annual uptake of carbon from a Q. myrsinaefolia tree with dbh of 10 cm were 24.0 kg and 4.5 kg/yr, respectively. A C. japonica tree and L. indica tree with dg of 10 cm stored 11.2 kg and 8.1 kg of carbon and annually sequestered 2.6 kg and 1.2 kg, respectively. The above-mentioned carbon storage equaled the amount of carbon emitted from the gasoline consumption of about 42 L for Q. myrsinaefolia, 20 L for C. japonica, and 14 L for L. indica. A tree with the diameter size of 10 cm annually offset carbon emissions from gasoline use of approximately 8 L for Q. myrsinaefolia, 5 L for C. japonica, and 2 L for L. indica. The study pioneers in quantifying biomass and carbon reduction for the landscape tree species in the southern region despite difficulties in direct cutting and root digging of the planted trees.

  • The present investigation was carried out to study the affect of feeding urea ammoniated neem kernel meal on carcass characteristics and organoleptic properties of the meat in goats. Eight local weaned kids of 3-4 months age with mean body weight of $7.85{\pm}0.42kg$ were assigned to two groups of four each in a completely randomised design and were offered diets containing isonitrogenous concentrate mixtures containing either peanut meal or urea ammoniated neem (Azadirachta indica) seed kernel meal (UANSKM) along with ad libitium oat hay or green sorghum as roughage for 13 fortnights. The animals were slaughtered at the end of the experimental period and the carcass characteristics and organoleptic evaluation of the meat was carried out. The carcass characteristics in terms of dressing percentage, meat bone ratio, percent edible and inedible did not differ between the treatments. Similarly the organoleptic characteristics and cooking loss were comparable between the treatments implying that UANSKM can be substituted for peanut meal in goat diets to alleviate the shortage and high cost of peanut meal without affecting meat quality.
