Purificationi of egg yolk immunoglobulin(IgY) was performed to understand the property of egg immunoglobulin. IgY differs from mammalian IgY in the molecular size(larger), isoelectric point(more acidic), and binding ability with mammalian complement and protein A(nonbinding ability). IgY is also known as ${\gamma}$-livetin and exists in egg yolk together with other two water-solubel proteins, ${\alpha}$-livetin(chicken serum albumin) and ${\beta}$-livetin(${\alpha}_2$-glycoprotein) and various lipoproteins(Low density lipoprotein, LDL and High density lipoprotein, HDL) which are the major components of egg yolk. The first step of isolation of IgY is to separate the water-solube proteins from lipoproteins. We report a simple method for separation of water soluble proteins using k-carrageenan and sedimentation. k-carrageenan was found to be effective for removal of yolk lipoprotein as a precipitate. IgY remained supernatant, and was isolated by chromatography on columns of DEAE-Sephacel and G 75 gel filtration chromatography.

Purpose : The aim of this study is to examine the effect of the phenol compound-cold therapy plus exercise therapy on the carrageenan(CAR)-induced muscle pain. Method : Mice were injected 0.1ml of 2% CAR into the gastrocmemius(GAS) muscle for the induction of muscle pain. After 4 hours from the injection of CAR, the cold therapy with 1% syringic acid was done to GAS muscle. After 2 hours from cold therapy, the exercise therapy such as muscle stretching, climing- and declining-movements was performed three times interval of 10 minutes in each experimental group. After 4, 10 and 24 hours from CAR-induced muscle pain, the measurements of muscle diameter, paw withdrawal latency(PWL) and, tail flick latency(TFL) were carried out. Results : In this study, the thickness of GAS muscle in CAR-induced muscle pain significantly increased compared with control. While, the thickness of GAS muscle adopted cold syringic acid-therapy with exercise-therapy group was significantly decreased than that of CAR-induced muscle pain. In the measurements of PWL and TFL, cold syringic acid-therapy with exercise-therapy group was remarkably increased than CAR-induced muscle pain group in PWL and TFL. All measurements were showed significantly different between the treated-group and the treated-time. Conclusions : From these results, it is suggested that the cold syringic acid-therapy with exercise-therapy such as muscle stretching, climing- and declining-movement was effective in the prevention of CAR-induced muscle pain by the decrease of muscle thickness and the increase of PWL and TFL.

In this studies, the adsorption test using Chlorella pyrenoidosa was conducted to examine the effect of Pb adsorption according to various immobilized methods such as Ca-alginate, K-carrageenan, and Polyacrylamide. From the results, the duration to need to reach adsorption equilibrium was delayed according to the immobilization. And, the higher adsorption capacity of immobilized Chlorella pyrenoidosa was represented in the higher concentration of Pb, the smaller amount of immobilizing agent, and the higher pH of solution. The maximum adsorption capacity of Pb was shown in the adsorption test using Chlorella pyrenoidosa immobilized with Ca-alginate even though it was sensitive pH. The adsorption results properly represented with Freundlich isotherm equations. And, pseudo second-order chemisorption kinetic rate equation was applicable to all the biosorption data over the entire time range. The FT-IR analysis showed that the mechanism involved in biosorption of Pb by Chlorella pyrenoidosa was mainly attributed to Pb binding of carbo-acid and amide group. Adsorbed Pb on immobilized Chlorella prenoidosa was easily desorbed in the higher concentration of desorbents(NTA, HCl, EDTA, $H_2SO_4,\;Na_2CO_3$). Among the several desorbents, NTA showed the maximum desoption capacities of Pb from Chlorella pyrenoidosa immobilized with Ca-alginate and K-carrageenan and EDTA was the most effective in Chlorella pyrenoidosa immobilized with polyacrylamide. The desoprtion efficiency in the optimum condition was 90.0, 83.0, and 80.0%, respectively.

The biosorption performances of copper were investigated by the immobilized biomass of nonliving marine brown algae Undaria pinnatifida by each of the Ca-alginate method(Ca-ALG), Ba-alginate method(Ba-ALG), polyethylene glycol method(PEG), and carrageenan method (CARR). The copper removal performance increased but the copper uptake decreased as the biomass amount was increased. However, the copper uptake by the immobilized biomass increased with increasing initial copper concentration. Among the immobilization methods, the copper uptake decreased in the following sequence: Ca-ALG > Ba-ALG > PEG > CARR. The pattern of copper uptake by the immobilized biomass fitted the Langmuir isotherm better than the Freundlich isotherm. Desorption of deposited copper with 0.05 ~0.5M HCI, resulted in no changes of the copper uptake capacity of the immobilized biomass by the immobilization methods except for PEG, through five subsequent biosorption/desorption cycles. There was no damage to the immobilized biomass which retained its macroscopic appearance in repeated copper uptake/elution cycles.

Leonuri Fructus, a semen of Leonuri Herba, has been used for the treatment of menstrual disorders such as amenorrhea, dysmenorrhea and leukorrhea and for the remedy of hyperemia. The present study was conducted to evaluate the anti-inflammatory effects of the Leonuri Fructus extract (Leonurus japonicus Houtt. EtOH extract; LJE) in vivo and in vitro. In vitro study, the MTT assay for cell viability was conducted to determine the non-cytotoxic concentration of LJE treatment in media. The levels of NO were measured with Griess reagent. Pro-inflammatory cytokines were detected by ELISA method. The inflammation-related proteins of this study were detected by immunoblot anlaysis. The increases of NO production and iNOS expression were detected in LPS-treated cells compared with control, but LJE attenuated the increases of NO and iNOS by LPS. LJE reduced the production of TNF-${\alpha}$ and IL-$1{\beta}$ induced by LPS stimulation. LJE suppresses the signaling pathways of NF-${\kappa}B$ and MAPKs in LPS-induced macrophage cells. In vivo study, carrageenan-induced hind paw acute edematous inflammation rat model was used for evaluation of anti-inflammatory activity of LJE. LJE significantly inhibited the increases of hind paw swelling, skin thicknesses and inflammatory cell infiltrations, and decreased the numbers of mast cell induced by carrageenan injection. These results suggest that LJE has an anti-inflammatory therapeutic potential, which is mediated through modulating NF-${\kappa}B$ activation and MAPK phosphorylation. Inhibition of the rat paw edema induced by carrageenan is considered as direct evidence that LJE may be a useful source to treat inflammation.

The synthesis of a novel superabsorbent hydrogel with natural hybrid backbone via graft copolymerization of acrylamide (AAm) onto kappa-carrageenan (kC, as a polysaccharide) and gelatin (as a protein) under classic thermal conditions is described. The Taguchi method as a strong experimental design tool was used for synthesis optimization. A series of hydrogels were synthesized by proposed conditions of Qualitek-4 Software. Considering the results of 9 trials according to analysis of variance (ANOVA), optimum conditions were proposed. The swelling behavior of optimum hydrogel was measured in various solutions with pH values ranging from 1 to 13. In addition, swelling kinetics, swelling in various organic solvents, various salt solutions and On–Off switching behavior were investigated. The hydrogel formation was confirmed by Fourier transform infrared spectroscopy (FTIR) and thermogravimetrical analysis (TGA). Surface morphology of the synthesized hydrogels was assessed by scanning electron microscope (SEM).

The present study was carried out to elucidate the potential of, chloroform extract of Pandanus (P.) fascicularis Lamk (Family-Pandanaceae) leaves on antinociceptive, behavioral study and anti-inflammatory effects using various animal models The dried, powdered leaves of, P. fascicularis were extracted successively with petroleum ether ($60\;-\;80^{\circ}C$) and chloroform in soxhlet apparatus. The chloroform extract (yield 21.6% w/w with respected to dry powdered plant material) was selected for all experimental procedure. Two models were employed to investigate the effects on nociception, the tail immersion and hot plate method in Swiss albino mice and anti inflammatory effect were investigated by employing the carrageenan induced rat paw edema test in. adult Wister albino rats. Behavioral study was investigated by elevated plus maze method in Swiss albino mice. Results were revealed that the PFCE was found significant antinociceptive effect (P < 0.001) at the dose levels of 100, 200 and 400 mg/kg, orally in mice and produced remarkable antiinflammatory effect (P < 0.001) at the same dose levels used in the rats. Behavioral study of the PFCE has no significant anxiolysis effect when used orally. It concludes that, PFCE possessed remarkable antinociceptive effect and anti-inflammatory effect but no anxiolytic effect on animal models.
