Purpose: The purpose of this study was to identify the causes, symptoms, and complications of hypoproteinemia to prevent hypoproteinemia and provide appropriate treatment to children with atopic dermatitis. Methods: Children diagnosed with atopic dermatitis with hypoproteinemia and/or hypoalbuminemia were retrospectively reviewed. The patients' medical records, including family history, weight, symptoms, treatment, complications, and laboratory test results for allergies and skin cultures, were examined. Results: Twenty-six patients (24 boys) were enrolled. Seven cases had growth retardation; 7, keratoconjunctivitis; 6, aural discharges; 5, eczema herpeticum; 4, gastrointestinal tract symptoms; and 2, developmental delays. In 21 cases, topical steroids were not used. According to the blood test results, the median values of each parameter were elevated: total IgE, 1,864 U/mL; egg white-specific IgE, $76.5kU_A/L$; milk IgE, $20.5kU_A/L$; peanut IgE, $30kU_A/L$; eosinophil count, $5,810/{\mu}L$; eosinophil cationic protein, $93.45{\mu}g/L$; and platelet count, $666.5{\times}10^3/{\mu}L$. Serum albumin and total protein levels decreased to 2.7 g/dL and 4.25 g/dL, respectively. Regarding electrolyte abnormality, 10 patients had hyponatremia, and 12, hyperkalemia. Systemic antibiotics were used to treat all cases, and an antiviral agent was used in 12 patients. Electrolyte correction was performed in 8 patients. Conclusion: Hypoproteinemia accompanying atopic dermatitis is common in infants younger than 1 year and may occur because of topical steroid treatment continuously being declined or because of eczema herpeticum. It may be accompanied by growth retardation, keratoconjunctivitis, aural discharge, and eczema herpeticum and can be managed through skin care and topical steroid application without intravenous albumin infusion.

Radiation effects on carbohydrate moiety of chicken ovomucoid, a protease inhibitor as a typical allergenic glycoprotein of egg white, was observed. The trypsin inhibitory activity of chicken ovomucoid decreased exponentially and the inactivation was more significant irradiated in $N_2$ than in $O_2$. From the protein blotting, radiation caused protein degradation in $O_2$ and protein aggregation also in $N_2$. The patterns of carbohydrate blotting were also similar with that of protein blotting. Sugar chains in low molecular weight fraction (MW<5,000) were released by radiation and those in $O_2$ were higher than in $N_2$. From the HPLC patterns of the degradation of sugar chains, all peaks of oligosaccharides have the tendency to decrease with the increase of radiation dose and more remarkable in $O_2$ than in $N_2$. These results suggest that ionising radiation could cause the overall conformational changes of ovomucoid by the degradation and release of oligosaccharides.

The aim of this study was to evaluate the potential of fermented red ginseng extract (FRGE) as feed additive in broilers and laying hens. In broilers, 480 Arbor Acre male broilers were randomly allotted to 4 treatments with 6 replications per treatment and 20 chicks per pen. The experiment lasted 5 weeks and dietary treatments were as follows: i) CON, basal diet; ii) FRGE1, basal diet+1 g/kg fermented red ginseng extract; iii) FRGE2, basal diet+2 g/kg fermented red ginseng extract and iv) FRGE3 basal diet+4 g/kg fermented red ginseng extract. Throughout the experiment, no effects were observed (p>0.05) in performance in response to FRGE. At the end of the experiment, FRGE administration improved (p<0.05) the lymphocyte level compared with CON. The relative weight of bursa of fabricius and spleen were increased (p<0.05) by the inclusion of FRGE3. Besides, redness ($a^*$) value for the breast meat was higher (p<0.05) in FRGE1 and FRGE3 treatments than that in CON. In laying hens, 240 ISA brown layers at 35 weeks of age were used in this 8-week trial. Dietary treatments were the same as in the broilers trial with 10 replicates per treatment and 6 layers per replicate. During the entire experiment, there were no significant differences (p>0.05) in performance or egg quality among all the treatments. However, the layers fed diets supplemented with FRGE had higher lymphocyte level (p<0.05) compared with those fed CON. In conclusion, the dietary supplementation with FRGE did not influence performance but improved the lymphocyte level in both broilers and laying hens.

Freeze-drying process was used for 10 major protein foods referred by the Korea Health Statistics 2011 as follows; chicken, pork, beef, eggs, tofu, squid, soybean, mackerel, anchovy, and pollack/frozen pollack. Boiled samples and re-hydrated samples after freeze-drying were prepared for analysis. The weight variation, the chromaticity, the mechanical texture and sensory properties by eight trained panelists were measured. In the ratio of re-hydration, the anchovy showed the highest value(89.40%), followed by eggs, and squid showed the lowest value(35.51%). Changes of Hunter color value were observed among all samples. For rates on changes of hardness, every sample was increased except for eggs(p<.05). Among the 9 samples, except for eggs, chicken showed the lowest rate of increase in hardness(125.44%) while squid showed the highest rate of increase in hardness(1335.1%). Except for eggs and pork, eight samples represented differences in sensory properties, especially in juiciness and tenderness(p<.05). As a result, we found that egg is the most suitable for freeze-drying among 10 protein sources followed by pork and chicken.

This experiment was carried out to investigate the effect of gamma ray on the eggs of later stage in late fall rearing season. The results are summarized as follows: 1. The duration of larval stage was simmilar to that of control in any dose. The silkworm growth was uniform in does of 4,000 gamma ray, but in does of 8,000r 16000r was irregular. There were not malformed silkworms but many small silkworm. 2. Mortality of silkworms was very high 8,000r and over; virus diseases of 87.6 per cent, flacherie of 5.9 per cent and complication of 6.5 per cent. 3. The more the dose of gamma ray became, the lighter the weight full grown silkworm and matured silkworm became. 4. The uniformness of cocoons was registered in dose of 2,000r and the cocoons were irregular or small in dose of 16,000r

A study was conducted to investigate possibility of utilizing dried citrus peel (DCP) as an ingridient of broiler diets. Fresh citrus peels were collected from a citrus processing plant, and were sun-dried and ground. Both chemical analyses and a feeding trial were carried out. DCP was analyzed for proximate nutrients, amino acids and some minerals. In the feeding trial, a total of 192 day-old female broiler chicks of Manor strain was divided into 16 groups of 12 birds each. Each group was fed one of the 4 different levels(0, 2, 4 and 6%) of DCP replacing an equivalent amount of wheat bran in the diet with 4 replications for 6 weeks. Body weight gain, feed intake and feed efficiency of broilers fed different levels of DCP showed no significant differences among treatments. Immediately after termination of the feeding trial, cach bird was examined for shank color using Roche's Egg Yolk Color Fan. Shank color index of birds increased consistently (P＜0.05) as the level of DCP fed increased, indicating that DCP can be used as a source of pigments. It was concluded from the results that DCP could be used up to 6% in place of wheat bran in broiler diets without adverse effects.

The diapause and non diapause associated proteins of multivoltine silkworm eggs were analysed by two dimensional (2D) gel electrophoresis. The study was made at 0 hr, 24 hrs and 48 hrs after oviposition. A total of four protein spots in diapause eggs at 24 hrs of oviposition and two protein spots in non diapause eggs at 0 hrs of oviposition were observed. All the six protein spots were considered to have association with diapause and non diapause characters. The molecular weight (MW) and isoelectric point (PI) of these 6 protein spots were calculated. The protein spots 1 and 2 observed in 0 hr of non diapause eggs were found to have the MW of 67 and 75 KDa and PI of 8.6 and 8.4 respectively. Similarly the four protein spots observed in diapause egg at 24 hrs of oviposition exhibited MW viz., 15, 17,20 and 25 KDa and PI of 5.3, 5.8, 6.5 and 6.0 respectively. All these 6 identified protein spots were subjected to in-gel digestion and resulted tryptic peptides were analyzed by Matrix-assisted laser desorption/ionization time-of flight mass spectrometry (MALDI TOF-MS). Databases searched based on experimentally determined molecular weights of peptides for the determination of the identities of proteins. The identified proteins indicated homology of 34% to 95%. The results indicate that the proteins may playa role in development of diapause and non diapause eggs.

Three types of proteases (MEF-1, MEF-2 and MEF-3) were purified from the egg cases of Ten-odera sinensis using ammonium sulfate fractionation, gel filtration on Bio-Gel P-60 and affinity chromatography on DEAE Affi-Gel blue gel. The proteases were assessed homogeneous by SDS-polyacrylamide gel electrophoresis and have molecular weight of 31,500, 32,900 and 35,600 Da, respectively. The N-terminal regions of the primary structure were compared and they were found to be different each other. MEFs readily digested the $A\alpha$ - and B$\beta$-chains of fibrinogen and more slowly the ${\gamma}$-chain. The action of the enzymes resulted in extensive hydrolysis of fibrinogen and fibrin, releasing a variety of fibrinopeptides. MEF-1 was inactivated by Cu$^{2+}$ and Zn$^{2+}$ and inhibited by PMSF and chymostatin. MEF-2 was inhibited by PMSF, TLCK. soybean trypsin inhibitor. MEF-3 was only inhibited by PMSF and chymostatin. Antiplasmin was not sensitive to MEF-1 but antithrombin III inhibited the enzymatic activity qf MEF-1. MEF-2 specifically bound to anti plasmin Among the chromogenic protease substrates, the most sensitive one to the hydrolysis of MEFs was benzoyl-Phe-Val-Arg-p-nitroanilide with maximal activity at pH 7.0 and 3$0^{\circ}C$. MEF-1 preferentially cleaved the oxidized B-chain of insulin between Leu15 and Tyr16. In contrast, MEF-2 specifically cleaved the peptide bond between Arg23 and Gly24. D-dimer concentrations increased on incubation of cross-linked fibrin with MEF-1, indicating the enzyme has a strong fibrinolytic activity.ity.

There is a need for newer feed additives due to legal prohibition on inclusion of growth promoting antibiotics in livestock diets in several countries due to antimicrobial resistance. In this context, rare earth elements (REE) have gained attention among animal nutritionists as potential growth promoters. Currently, several studies have reported better weight gain, milk production, egg laying capacity and feed conversion efficiency among different breeds of farm animals following supplementation with REE, with however largely inconsistent results. Furthermore, REE supplementation has also shown to improve ruminal fibrolytic and proteolytic activities as well as flavor of meat with negligible residues in edible tissue, however the mechanism behind this action is still unclear. According to existing research, due to their poor absorption and similarity with calcium REE might exert their action locally on gut microbial populations within the gastrointestinal tract (GIT). Moreover, REE have also shown anti-inflammatory, anti-oxidative as well as immune stimulating effects. The present review aims to broaden the knowledge about use of REE as feed additives for livestock and sum up efficacy of REE supplementation on performance and health of animals by comparing the findings. Till date, researches with REE have shown properties that make them a promising, new and safe alternative feed additive but further exploration is recommended to optimize effects and clarify discrepancy of various results before practical proposals can be drafted.
