Sorghum bicolor L. Moench(Sorghum, Su-Su) is a major cereal food crop used in many parts of the world. It is used as a human food resource and folk medicines in Asia and Africa. The stem of sorghum has been used as a digestive aid and an anti-diarrheal agent. Sorghum hybrids contain high levels of diverse phenolic compounds that may provide health benefits. High levels of polyflavanols, anthocyanins, phenolic acids, and other antioxidant compounds have been reported in sorghums, which have also been shown to possess various biological activities such as anti-mutagenic, anti-carcinogenic, and HMG-CoA reductase inhibitory activities. In an in vitro experiment, we examined mice splenocyte proliferation and production of three types of cytokine($IL-1{\beta},\;IL-6,\;TNF-{\alpha}$) by peritoneal macrophages cultured with ethanol and water extracts of Sorghum bicolor L. Moench. A single cell suspension of splenocytes was prepared and the cell proliferation of the splenocytes was examined by MTT assay. The splenocyte proliferation was increased when water extracts of Sorghum bicolor L. Moench were used as supplements in all concentrations investigated. The production of cytokine($IL-1{\beta},\;IL-6,\;TNF-{\alpha}$) by activated peritoneal macrophage was detected by ELISA using the cytokine kit. $IL-1{\beta},\;IL-6,\;and\;TNF-{\alpha}$ production by activated macrophages were increased by supplementation with Sorghum bicolor L. Moench water extracts. This study suggests that supplementation of with Sorghum bicolor L. Moench water extracts may enhance immune function by regulating the splenocyte proliferation and enhancing the cytokine production by activated macrophages in vitro.

This study was performed to evaluate the effect of Sorghum bicolor L. Moench(Sorghum, su-su) extracts on mouse immune cell activation. As ex vivo experiment, different concentrations(0, 50, 500mg/kg B.W.) of Sorghum bicolor L. Moench water extracts were orally administrated into mouse every other day for four weeks. The proliferation of mouse splenocytes, the number of plaque forming cells(PFC) and the cytokine IL-1β production by activated macrophage were used as indices for immunocompetence. Splenocyte proliferation was enhanced in mouse orally administrated with 50mg/kg B.W./day concentration compared to that of control group. Especially, the highest proliferation of spleoncyte was seen in the mouse orally administrated at the concentration of 50mg/kg B.W./day. The number of plaque forming cells(PFC) to SRBC were significantly enhanced when compared with control group. Also, the mouse of Sorghum bicolor L. Moench water extracts 50mg/kg B.W./day supplementation group with LPS stimulation enhanced level of IL-1$\beta$ cytokine production. This study suggest that supplementation of Sorghum bicolor L. Moench water extracts may enhance the immune function by regulating the splenocytes proliferation, increasing the number of PFC and enhancing the cytokine production by activated macrophage.

This experiment was conducted to provide comparative data on the newly imported thirteen sorghum-sudangrass hybrids(Sorghum bicolor(L.) Moench), TE Goldmaker sorghum hybrid (S. Bicolor (L.) Moench), NC+ 88SS sudangrass hybrid (S, bicolor (L.) Moench), Supermill pearlmillet (Pennisetum americanum (L.) Leeke) and teosinte (Euchlaena mexicana Schrad,) in comparison with the check variety Pioneer 988 sorghum-sudangrass hybrid for dry matter yield, protein content, in vitro dry matter digestibility(IVDMD), and other desirable agronomic characteristics, SX-17 and NC+855 gave significantly higher dry matter yield than the check variety. There was no significant difference in total dry matter yield of the remaining 14 varieties with the exception of teosinte and TE Goldmaker which had the lowest yield. The most varieties were moderately resistant to leaf diseases although differences exist among varieties. No diseases were found in pearlmillet and teosinte, but NC+ 88SS was very susceptible to leaf blight. The mean percent crude protein of sorghum-sudangrass hybrids was lower than that of pearlmillet and sorghum hybrid, but was higher than that of sudangrass hybrid, The IVDMD of G-83F, TE Goldmaker, teosinte and HW 5111 was higher than that of the check variety. There was no consistent relationship between the percent of crude protein and IVDMD of the summer annual grasses.

The LIM domain-containing proteins are dominantly found in plants and play a significant role in various biological processes such as gene transcription as well as actin cytoskeletal organization. Nevertheless, genome-wide identification as well as functional analysis of the LIM gene family have not yet been reported in the economically important plant sorghum (Sorghum bicolor L.). Therefore, we conducted an in silico identification and characterization of LIM genes in S. bicolor genome using integrated bioinformatics approaches. Based on phylogenetic tree analysis and conserved domain, we identified five LIM genes in S. bicolor (SbLIM) genome corresponding to Arabidopsis LIM (AtLIM) genes. The conserved domain, motif as well as gene structure analyses of the SbLIM gene family showed the similarity within the SbLIM and AtLIM members. The gene ontology (GO) enrichment study revealed that the candidate LIM genes are directly involved in cytoskeletal organization and various other important biological as well as molecular pathways. Some important families of regulating transcription factors such as ERF, MYB, WRKY, NAC, bZIP, C2H2, Dof, and G2-like were detected by analyzing their interaction network with identified SbLIM genes. The cis-acting regulatory elements related to predicted SbLIM genes were identified as responsive to light, hormones, stress, and other functions. The present study will provide valuable useful information about LIM genes in sorghum which would pave the way for the future study of functional pathways of candidate SbLIM genes as well as their regulatory factors in wet-lab experiments.

In this study cadmium content of sorghum hybrid (Sorghum bicolor) was analyzed using atomic absorption spectrophotometer at different burner heights (3, 6, 9 mm). We considered the 6 mm burner height condition favorable among the three. The mean Cd content of each treatment are as follows: Alum+NPK, 1.90 mg/kg; Control, 3.14 mg/kg; Compost, 3.35 mg/kg; and Compost+NPK, 4.23 mg/kg.

Effect of Water Treatment Sludge(WTS) on trace metals content in Sorghum(Sorghum bicolor(L.) Moench) was investigated. At this report measuring of nickel(Ni) content of the forage was presented. Four treatments, Control, Compost, Alum+(nitrogen, phosphorus, potassium)(NPK), Compost+NPK, were applied to the sorghum in a mountainous place near the Joongbu University. With the 1, 3, 5 hours conditions, the background value was the least on the 5 hours warming up of the AA-680 spectrophotometer, and on the condition(mean/SD) of absorbances of Ni observed was the most. It is necessary in Ni analysis warming up for longer period around 5 hours for this type of apparatus. And we think that the difference of warming time for Ni analysis in order to carry out better measuring; the reason might be the larger bonding energy of Ni than those of Cu, calcium(Ca), magnesium(Mg) and (potassium)(K).

These experiments were conducted to determine the effects of Sorghum allelopathic substances on the callus growh of several weeds and crops. 1. When substances extracted from allelopathic Sorghum(Sorghum bicolor L.) were treated on medium, growth of callus of several weeds and crops were in-hibited. The degree of inhibition differed depending on the genotypes, ranging from 50 to 90% com-pared with that of control. 2. The extracts of above 5% Sorghum inhibited the callus growth of Che-nopodium albun L., Commelina communis L., and .Ammaranthus retroflexus L.and showed in-hibition rate of above 70% in callus growth. These results indicate that we could investigate theallelopaihy effect by using in vitro system. 3. The suitable explant for callus induction fromallelopathic plants was immature embryos, the callus induction rate differed depending on the geno-type, growth regulators and concentrations. In general, the addition of 2, 4-D and NAA onto medium increased the rate and amount of callus.

We have studied effect of water treatment sludge (WTS) on trace metals of sorghum hybrid (Sorghum bicolor (L.) Moench). In the present report it was for cadmium (Cd) content on background correction (BGC) mode with an atomic absorption spectrophotometer. The four treatments were Control, Compost, Alum + nitrogen, phosphorus, potassium (NPK), Compost + NPK. In the analysis, burner height of the atomic absorption spectrophotometer was adjusted to three levels; 3 mm, 6 mm, 9 mm. As a conclusion, 3 mm and 6 mm burner height conditions were better than 9 mm height for Cd analysis. And the conditions for widening the range, the mean, and the standard deviation (SD) values of observed absorbances as well as the condition for lessening the mean of observed background values are necessary for getting the better measuring of Cd. At the present experiment, 6 mm burner height condition is the best among the three burner heights.

To examine the antioxidant activities of 11n selected miscellaneous cereal grains (proso millet, yellow glutinous proso millet, hwanggeumchal sorghum, glutinous sorghum, white glutinous sorghum, yellow glutinous foxtail millet, nonglutinous foxtail millet, green glutinous foxtail millet, golden foxtail millet, barnyard millet, and adlay), the free radical-scavenging activities of 80% ethanol extracts of the individual grains were investigated using 1,1-diphenyl-2-picryl-hydrazl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) methods. The ethanol extracts of hwanggeumchal sorghum, glutinous sorghum, and barnyard millet grains exhibited more potent free radical-scavenging activities as compared to the other grains. When these three ethanol extracts were sequentially fractionated with n-hexane, methylene chloride, ethyl acetate, and n-butanol, the majority of the antioxidant activities were detected in the ethyl acetate and butanol fractions in which phenolic ingredients were abundant. The ethyl acetate and butanol fractions of hwanggeumchal sorghum and the ethyl acetate fraction of glutinous sorghum showed higher antioxidant activity than that of ${\alpha}$-tocopherol. Both ferric thiocyanate (FTC) and thiobarbituric acid (TBA) methods demonstrated that these organic solvent fractions could inhibit lipid peroxidation. The ethyl acetate fractions from hwanggeumchal sorghum, glutinous sorghum, and barnyard millet grains could suppress tertiary-butyl hydroperoxide (TBHP)-induced apoptotic events, including sub-G1 peaks, ${\Delta}{\Psi}m$ loss, activation of caspase-9 and caspase-3, and cleavage of PARP and lamin B, in human HL-60 cells. These results show that the grains of hwanggeumchal sorghum (Sorghum bicolor L. Moench cv. Hwanggeumchalsusu), glutinous sorghum (Sorghum bicolor L. Moench cv. Chalsusu), and barnyard millet (Echinochloa esculenta) possess efficient antioxidant activity, which could protect cells from oxidative stress-mediated cytotoxicity.
