An investigation was performed to reveal the removal rates of organic constituents of the litters in a Phragmithea longivalvis grassland in a Delta of the Nakdong River, The removal rates of the inorganic and organic materials are determined by the mathematical models. The removal rates and time required to decay up to a percentage of each organic constituent were calculated using these new models. The removal rates of cold water soluble fractions, other carbohydrates, hot water soluble fractions, cellulose, crude fat, lignin and crude protein were 2.67, 1.39, 1.25, 1.02, 0.92, 0.49 and 0.47, respectively, The periods required to reach half time to the steady state of the removal and accumulation for cold water soluble fractions, other carbohydrates, hot water soluble fractions, cellulose, crude fat, lignin and crude protein of the litter were 0.26, 0.50, 0.55, 0.68, 0.75, 1.41 and 1.48 years, respectively.

Protein kinase C, a protein related in PI cascade, was partially purified from the cytosol protein of etiolated plants of Glycine max by DEAE-52 cellulose chromatography and phenylsepharose chromatography. When the DEAE column was eluted with 0-0.8 M linear gradient KCl, tow fractions were found that increased the phosphorylation of histon H1 about five and nine-fold in the presence of 5 $\mu\textrm{g}$/mL phosphatidylserine and 0.5 $\mu\textrm{g}$/mL diolein, respectively. These fractions were used as DEAE pool. The reaction eluted with relatively high concentration of KCl was loaded on phyenylsepharose column with 5 mM CaCl2 and eluted with 1 mM EGTA. A fraction contained the protein kinase C, which increased the phosphorylation of the histon H1 was fractionated. To determine the molecular weight of PKC, the fraction eluted from phenylsepharose column was analyzed by 5~15% polyacrylamide gel electrophoresis after concentrated with the Amicon membrane (YM10). That revealed two bands corresponding to 60 and 65 kGy by silver staining of the gel, respectively.

Serum proteins of Korean native dogs (Gyeongju DongGyeong dogs) was analyzed by capillary electrophoresis system. Electrophoretic patterns showed six fractions. Total serum protein and ratio of albumin to globulin were $5.99{\pm}0.83$ (g/dl) and $1.41{\pm}0.29$ (g/dl) in DongGyeong dogs. Relative percentages of total serum albumin and $\alpha-1$, $\alpha-2$, $\beta-1$, $\beta-2$, $\gamma$-globulin fraction were $57.94{\pm}5.43$, $3.15{\pm}2.30$, $7.49{\pm}4.09$, $9.43{\pm}3.50$, $7.63{\pm}5.70$, and $14.36{\pm}7.63$, respectively. It was observed that $\beta$-globulin was higher than other fractions. The most striking alternation with age was founded in the $\gamma$-fractions. Also, it was observed that ratios of albumin to globulin in DongGyeong dogs were higher than on other dogs.

The cultured mycelia of Ganoderma lucidum were extracted and the extract was separated into six fractions by organic solvent fractionation. The antihepatotoxic activity of all the fractions was evaluated by measuring activities of glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminase (GOT). Among the fractions tested, the high-polarity fractions such as aqueous and n-butanol fractions significantly reduced activities of GPT and GOT in CCl4- and galactosamine-intoxicated rat primary hepatocytes. When intracellular synthetic activities were measured by pulsing the rate primary cultured hepatocytes with [3H]-uridine and [3H]-leucine, activities of DNA, RNA and protein. When direct toxicities of the fractions were measured against human hepatoma(SK-Hep-1), the non-polarity fractions such as n-butanol and ethyl acetate fractions showed potent direct cytotoxicities even at the concentration of 1 $\mu\textrm{g}$/ml. These data showed that Ganoderma lucidum has hepatoprotective and hepatotoxic recovery principles in its mycelia.

Protein expression patterns in Salmonella enterica subspecies enterica serovar Typhimurium (S. Typhimurium) strains with diverse phenotypes, such as phage type, antibiotic resistance pattern and plasmid profiles were examined. For detailed analysis of proteins expressed by different S. Typhimurium strains, protein fractions were divided into detergent-rich phase (DP) and aqueous phase (AP) using triton X-114 detergent. The two phases were subjected to two-dimensional gel electrophoresis (2-DE), followed by protein identification using peptide mass fingerprinting (PMF). In the results, PMF showed that DP fractions consisted mainly of outer membrane proteins, whereas the AP fractions included cytosolic proteins. Comparison of 2-DE profiles of DP did not show any distinct protein spots which could be correlated with phage type, antibiotic resistance pattern or plasmid profile. However, comparisons of 2-DE profiles of the AP revealed differences in the protein spots, which could be correlated with the plasmid profile and phage types. Among these protein spots, flagellin was specific for strains containing a 90 kb plasmid. Compared to DT193 phage type, three protein spots in the range of pI 5.0-5.5 and MW 8-15 kDa of AP 2-DE profiles were absent in the DT104 phage types. Additionally, a protein spot with PI in the range of 4.5-5.0 and molecular weight (MW) between 51-69 kDa was specific for phage type DT104, while a protein spot with pI in the range of 4.0-4.8 and MW between 18-20 kDa was specific for DT193 phage type. These protein spots may be useful for discriminating phage types of S. Typhimurium.

1. The albumin, ${\beta}-globurin$ and ${\gamma}-globurin$ fractions of non-vaccinated bovine serum (Control) int declined, and a total protein and ${\alpha}-globurin$ level are advanced on the reversible rather than of vaccinated immumized bovine serum. (Table 5.) 2. Some few exists the to bring about changed in the individuals and sexual in a vaccinated bovine serum, however, Male serum globurin fractions are higher than Female globurin fractions percentage. (Table 1 and 3.) 3. Albumin fractions are Age-ablly variable, so that, younger's are rather lower than adult's such reported as in the another litratures. 4. In the monthly analysis of immunized bovine serum the first week to at dulation for third weeks were slowly advanced as variablly in serum-protein fractions of ater by the Black-leg No. 2 vaccination, then, albumin fractions were illustated as maximum ratio (42.73 3.49%) and increased much as 14.9% more than non-vaccinates, and ${\alpha}-globurin$ fractions indicated the minimum ratio(15.11 2.35%) at for 4th month after vaccination decrease much as about 7.71 % rather non-vaccinated normal bovine serum. (Table 4. and Fig 3.) Next, continuous advanced the ${\beta}-globurin$ fractions at first month as primary crisis in a diagram, and indicated the maximum ratio at 8th months as the second crieir on the its diagram of after vaccinati on, however, few changed in non-vaccinated bovine serum. (Figs 4.) Especially, ${\gamma}-globurin$ fractions are advanced the maximum ratio as 41. 45% 4.48% anp advanced to be widely range much as about 22.55% more than control serum at 5th months of after the vaccination. That is one of the most considerable evalution in Black-leg No. 2 vaccination to Korean calevs as great presence of the maximum immune antibodies at for 5th month after the vaccination. (Table 4. and Fig 4.) 5. In the relationship between vaccinated rabbit and Korean calves, serum protein fraractions were to be changed within the 3 weeks, so that albumin fractions of vaccinated immune bovine serum are increased as directly ratio, while vaccinated rabbit immunized serum showed the decrease as to reciprocal ratio. Although, conclude that ${\gamma}-globurin$ fractions are increased gradually by and large on the vaccinated immune bovine serum(B. P. S.) and vaccinated immune rabbit serum(R. P. S.) together. (Table 6).

Objective: To improve the utility of native grass resources as feed in China, we investigated the dynamics of protein and carbohydrate fractions among Inner Mongolian native grasses, during ensiling and the aerobic stage, using the Cornell Net Carbohydrate and Protein System. Methods: Silages were prepared without or with lactic acid bacteria (LAB) inoculant. We analyzed the protein and carbohydrate fractions and fermentation quality of silages at 0, 5, 15, 20, 30, and 60 d of ensiling, and the stability at 0.5, 2, 5, and 10 d during the aerobic stage. Results: Inner Mongolian native grass contained 10.8% crude protein (CP) and 3.6% water-soluble carbohydrates (WSC) on a dry matter basis. During ensiling, pH and CP and WSC content decreased (p<0.05), whereas lactic acid and ammonia nitrogen (N) content increased (p<0.05). Non-protein N (PA) content increased significantly, whereas rapidly degraded true protein (PB₁), intermediately degraded true protein (PB₂), total carbohydrate (CHO), sugars (CA), starch (CB₁), and degradable cell wall carbohydrate (CB₂) content decreased during ensiling (p<0.05). At 30 d of ensiling, control and LAB-treated silages were well preserved and had lower pH (<4.2) and ammonia-N content (<0.4 g/kg of fresh matter [FM]) and higher lactic acid content (>1.0% of FM). During the aerobic stage, CP, extract ether, WSC, lactic acid, acetic acid, PB₁, PB₂, true protein degraded slowly (PB₃), CHO, CA, CB₁, and CB₂ content decreased significantly in all silages, whereas pH, ammonia-N, PA, and bound true protein (PC) content increased significantly. Conclusion: Control and LAB-treated silages produced similar results in terms of fermentation quality, aerobic stability, and protein and carbohydrate fractions. Inner Mongolian native grass produced good silage, nutrients were preserved during ensiling and protein and carbohydrate losses largely occurred during the aerobic stage.

1. Amino acid compositions were determined by amino acid analyzer. Through the analysis of these samples, it was found that glutamic acid was the most abundant; glycine, aspartic acid, lysine and threonine were rich; and tryptophan and methionine were the limiting amino acid. 2. Albumins, globulins, gliadins and glutelins were extracted from the Kangwon hull, Kangwon rice buckwheat, and wheat. The relative proportions of protein fractions were 52.45 : 10.14 : 16.61 : 20.80% in Kangwon hull buckwheat, 21.10 : 13.80 : 28.40 : 36.70% in Kangwon rice buckwheat and 6.87 : 1.65 : 42.85 : 48.6% in wheat, in the order of albumins, globulins, gliadins and glutelins. 3. Polyacrylamide gel electrophoresis (PAGE) and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) were performed to identify the subfractions of each protein fraction. The electrophoregrams of PAGE showed that the same fractions of both Kangwon hull buckwheat protein and Kangwon rice buckwheat protein had very similar electrophoretic patterns to each other respectively, but there were significant differences in the patterns between buckwheat proteins and wheat proteins.

The crude polysaccharide from Panax ginseng prepared by hot water extration and precipiation with ethanol was further fractionated into neutral and acidic fractions by DEAE- cellulose ion exchange chromatography. The chemical compositions were 85.0% carbohydrorate and 15.0% protein for the neutral fraction, and 28.4% carbohydrate, 10.0% protein and 29.0% uronic acid for the acidic fraction. The acidic fraction was more effective in increasing of the ratio of spleen to body weight, the number of antibody secreting cells to SRBC and phagocytic activity of reticuloendothelial system, as well as antitumor activity against the solid form of sarcoma 180 in ICR mice than the neutral fraction. All polysaccharide fractions were mitogenic to cultured spleen cells of C57BL/6 mice. However, FA was different from FN in the co-mitogenicities with lectin mitogens. Both crude and acidic fractions potentiated remarkably the mitogenic activity of PHA-P or LPS in dose-dependent manner but neutral fraction enhanced only that of LPS. Three polysaccharide fractions had no effect on that of Con A. These results suggest that the acidic fraction may stimulate B and Td cells as well as macrophages while the neutral fraction may simulate only B cells and macropages.

The mechanisms by which leptospires caused disease are not well understood. A number of putative virulence factors have been suggested, but with few exceptions their role in pathogenesis remains unclear. In these days, many cases of leptospirosis are diagnosed by serological immunoassay. Leptospirosis is characterized by the histopathology of liver, kidney, heart, and lung, but the electrophoresis fractions of serum protein are not compared. We analyzed total protein, albumin, aspartic aminotranferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatinine and urea nitrogen (UN) in sera of patients diagnosed leptospirosis. Total protein and albumin were decreased in 18.5％ and 31.2％ of patients, respectively. AST, ALT, ALP, UN and creatinine were increased in 90.4％, 66.9％, 28.0％, 15.9％ and 10.8％ of patients, respectively. We performed cellulose acetate membrane electrophoresis (EP) on sera of patients increased both of AST and ALT, and of patients increased both of creatinine and UN. In patients increased both of AST and ALT, and in patients increased both of AST and ALT, the relative percentage of albumin to total protein in patient serum was dcreased in 89.1 ％ of patients. α₁-globulin, α₂-globulin, β-globulin and γ-globulin were increased in 85.1 ％, 75.2％, 33.6％ and 98.0％ of patients, respectively. In patients increased both of creatinine and UN, the relative percentage of albumin to total protein in patient serum was dcreased in 93.8％ of patients. α₁-globulin, α₂-globulin, β-globulin and γ-globulin were increased in 87.5％, 100％, 31.2％ and 93.8％ of patients, respectively. These data indicate that infection of Leptospira causes severe liver damage to most of leptospirosis patients, but doesn't cause renal damage to most of them. The relative rate of serum protein electrophoresis fractions to total protein are not identical with them of typical hepatitis patient.
