This study was conducted to examine the effects of dietary sources of fatty acids and protein on serum protein profiles, hepatic functional enzyme activities, mammary tumor incidence and tumor weight in 7, 12-dimethylbenz($\alpha$)anthracene (DMBA)-treated rats. The sources of dietary fatty acids were 18n6 (rich in linoleic acid), 18n3 (rich in linolenic acid) and 22n3 (rich in DHA) : sources of dietary protein were casein (C) and soy protein isolate (S). mammary tumors (MTs) were chemically induced by DMBA (9 mg/100 g body weight) which was gastrically intubated at 7 weeks of age. Each experimental diet was given for the following 25 weeks. Casein-fed rats (group C) exhibited significantly higher levels of weight gain and FER (food efficiency ratio) than did group S. Group C showed higher levels of serum protein and globulin, and higher albumin/globulin (A/G) ratios than group S. Liver functional enzyme activities (GOT, GPT, ALP, LDH, $\gamma$-GT) and LDH/GOT ratios were not influenced by dietary protein. GPT activity was lower in the group given 18n3, and ALP activity was lower in the group given 18n6. The incidence and total number of MTs appeared to be lower in the group given 22n3 than in the group given 18n3 or 18n6, even though the average weight of MTs was highest in the group given 22n3, The average weight of MTs was higher in the C group than in the S group. MT incidence had a positive correlation with LDH activity and LDH/GOT ratio. The average weight of MTs had a negative correlation with serum albumin levels and A/G ratios, and a positive correlation with ALP activity. This research suggests that the measurement of serum protein profiles and liver functional enzyme activities may be utilized to monitor the development of mammary tumors.

Simultaneous determination of concentrations for four major components in human blood serum was investigated using a Fourier-transform mid-infrared spectroscopy. Infrared spectra of human blood serum were measured in 8.404 ∼ 10.25 ${\mu}m$ range where the highest absorption peaks of glucose are located. A partial least square (PLS) algorithm was utilized to establish a calibration model for determining total protein, albumin, globulin and glucose levels which are commonly measured metabolites. The standard error of cross validation obtained from our multivariate calibration model was 0.24 g/dL for total protein, 0.15 g/dL for albumin, 0.17 g/dL for globulin, and 6.68 mg/dL for glucose, which are comparable with or meet the criteria for clinical use. The results indicate that the infrared absorption spectroscopy can be used to predict the concentrations of clinically important metabolites without going through a chemical process with a reagent.

Immunopotentiating activity of water extract of Lycii Fructus, Rubus Fructus, Torilis Fructus, Schizandrae Fructus and Cuscutae Semen were investigated using mouse fed with normal diet and protein deficient diet. Body weight, ratio of spleen or thymus to body weight, number of total peritoneal exudate cell, content of total serum protein and albumin content were decreased in the mouse fed with protein deficient diets as compared to the mouse fed with normal diet. Regardless of the nutritional condition, the supplement of the water extract of Lycii, Rubus Torilis, Schizandrae Fructus or Cuscutae Semen increased the ratio of spleen to body weight. The increment of this ratio was significant by the supplement of water extracts of Lycii and Torilis Fructus in mouse fed with protein deficient diet. The supplement of water extracts of Torilis Fructus to the mouse fed with protein deficient diet increased the content of total serum protein and albumin content significantly. Similar results were obtained with Lycii, Rubus, Schizandrae Fructus and Cuscutae Similar. The electrophorogram shows the difference in the concentration of some serum protein constituents between the mouse fed with normal diet and protein deficient diet.

This study investigated whether a correlation exists between proteinase activity, phospholipase activity and adherence of Candida albicans to buccal epithelial cells by using of various strains isolated from oral cavity. The proteinase activity of 30 strains was tested by culture on agar media that contained bovine serum albumin as a nitrogen source. Using the serum-protein-agar method to test proterolysis of serum albumin in 20 strains of Candida albicans. Twenty-six strains of Candida albicans were phospholipase producers and the degree of phopholipase activity of experimental strains were $0.51{\sim}0.89$ measured by Pz-value. Twenty-eight strains of Candida albicans were adhersive to buccal epithelial cells and 15 strains were foung significantly active adherence. Fifteen strains of Candida albicans were correlated with proteinase activity and adherence to epithelial cells and concomitantly 20 strains of Candida albicans were also correlated with phospholipase activity and adherence. In conclusion our investigation provides evidence of a correlation between quantitative proteinase, phospholipase and adherence. An association of these parameters may be an important contributory factor for pathogenicity.

Ampicillin sodium (AMP-Na) was loaded Into fibrin glue (FG) in two different ways and was tried to achieve sustained release from FG. One was loading of AMP-Na in a simple mixing and the other was loading of bovine serum albumin (BSA) microspheres which contained ANP-Na. In case of simple mixing, the release control of AWP-Na from FG was tried by variation of FBNG concentration, but failed. However, the loading of BSA mlcrosphere containing ANP-Na into FG showed sustained re- lease of AMP-Na, especially when microsphere was crosslinked with glutaraldehyde (tO.9 : 33hr). The maximum adhesive strength of FG showed at concentration of FBWG and thrombin, 5.0 % and 25-50 NIHU/ml, respectively. The concentration of Factor Xlll (0-500 U/1g of FBNG) did not affect the adhesive strength of FG. The optimal incubation time was 60 min. The AMP-Na or BSA microsphere which was loaded into FG had no significant effect on the adhesive strength of FG.

Protein affinity membranes based on polyethersulfone (PES) and bovine serum albumin (BSA) were prepared by using an electrospinning method. The changes in the size of nanofiber according to the various conditions of electrospinning (concentration of spinning solution, voltage, flow rate, tip to collector distance) were investigated, and the preparation conditions of the affinity membrane were optimized. XPS and FT-IR results showed the firm incorporation of BSA with PES. It was found PES-BSA nanofibers could be prepared at the temp. of $20{\sim}22^{\circ}C$ and humidity of $45{\sim}55%$. The size of nanofibers increased with increase of the content of PES in the spinning solution while BSA did not affect much to the size of nanofiber. It was also revealed that the narrow size distribution of nanofiber could be obtained with PES 7 wt%, BSA 0.7 wt%, HFP 92.3 wt% at the electrospinning conditions of 1 mL/hr, 10 cm TCD, and 10 kV.

Therapeutic drug monitoring of Mycophenolate mofetil(MMF) has been suggested in some clinical trials, but has not been widely adopted in Korea. The purpose of this study was to analyze the withdrawal rates of MMF and determine the characteristics of the patients who experienced adverse reactions with MMF therapy and to suggest the criteria for selecting patients who need monitoring of MMF levels. We retrospectively collected data of patients who started MMF between July 2007 and June 2008. A total of 154 adult patients were included in our study. Among them, ninety seven patients discontinued MMF with 59 cases being due to adverse drug reactions. Thirty one patients required dosage reduction of MMF with twenty three cases being due to adverse reactions. Twenty six patients continued the MMF without or with mild adverse reactions. Of the 82 adverse reaction cases, hematologic adverse reactions accounted for 38 cases (46%) and gastrointestinal (GI) adverse reactions accounted for 28 cases (34%). Older age and lower serum albumin levels were significantly different characteristics between the patients who withdraw MMF due to hematological adverse reactions and those who were able to continue therapy. The group who experienced GI adverse reactions had higher MMF dosages based on body weight and lower serum albumin levels. In conclusion, the factors affecting the adverse reactions of MMF were age, serum albumin level and higher dosage, therefore therapeutic drug monitoring of MMF should be considered in these patients.

This study was conducted to evaluate effect of ${\alpha}$-linolenic acid (ALA) and bovine serum albumin (BSA) on viability, acrosome reaction and mitochondrial intact in frozen-thawed boar sperm. The boar semen was collected by gloved-hand method and cryopreserved using freezing extender containing 3 ng/mL ALA and/or $20\;{\mu}g/mL$ BSA. Cryo-preserved boar sperms were thawed in $37^{\circ}C$ water-bath for 45 sec to analysis. Viability, acrosome reaction, and mitochondrial intact were analyzed using flow cytometry. In results, viability of frozen-thawed boar sperm was significantly higher in only ALA+BSA supplement group than control group (p<0.05), whereas there was no difference either in ALA or BSA supplement. However, acrosome reacted sperm in both of live and all sperm population were significantly decreased in all treatment groups than control (p<0.05). Interestingly, mitochondrial intact of boar sperm was enhanced in ALA and ALA+BSA groups compared with control (p<0.05). In this study, we showed that supplementation of ALA and BSA in freezing extender enhanced the sperm viability, mitochondrial intact and decrease acrosomal membrane damage. In conclusion, our findings suggest that quality of frozen-thawed sperm in mammalians could improve by using of ALA and BSA.
