Total and esterified cholesterol content was determined in the rat administered animal and vegetable proteins for 16 weeks. The cholesterol biosynthetic activity of the liver was also measured in these rats by the $acetate-C^{14}$ incorporation rate. The results obtained were as follows. (1) Serum total cholesterol content was increased by the administration of animal proteins and decreased by that of vegetable proteins. (2) Liver cholesterol content was increased by animal proteins and decreased by at of vegetable proteins. (3) Cholesterol biosynthetic activity of the liver was increased by the animal proteins and decreased by the vegetable proteins.

Fish muscles are classified into white and red muscles, and the chemical composition of the two fish muscles have many differences. Few reports have assessed the health-promoting functions of white fish muscle proteins (WFP) and red fish muscle proteins (RFP). We therefore evaluated the mechanisms underlying the alteration of lipid profiles and cholesterol metabolism following the intake of WFP prepared from cod and RFP prepared from light muscles of tuna. Male Wistar rats were divided into six dietary groups: casein (23%), WFP (23%), and RFP (23%), with or without 0.5% cholesterol and 0.1% sodium cholate. Compared to the WFP-containing diet, the RFP-containing diet supplemented with cholesterol and sodium cholate significantly increased serum and liver cholesterol contents. However, in the RFP groups, an alteration in cholesterol metabolism including an increased tendency to excrete fecal sterols and hepatic cholesterol $7{\alpha}$-hydroxylase was related to the reduction of hepatic cholesterol contents. This phenomenon might be related to the tendency of an increased food intake in RFP-containing diets. These results highlight the differential effects of WFP and RFP on serum and liver lipid profiles of Wistar rats fed non-cholesterol- or cholesterol-containing diets under no fasting condition.

Advancements in the field of proteomics have provided great opportunities for the development of diagnostic and therapeutic tools against human diseases. In this study, we analyzed haptoglobin and amyloid A protein levels of vivax malaria patients with combinations of depletion of the abundant plasma proteins, 2-dimensional gel electrophoresis (2-DE), image analysis, and mass spectrometry in the plasma between normal healthy donors and vivax malaria patients. The results showed that the expression level of haptoglobin had become significantly lower or undetectable in the plasma of vivax malaria patients due to proteolytic cleavage when compared to healthy donors on 2-DE gels. Meanwhile, serum amyloid A protein was significantly increased in vivax malaria patient's plasma with high statistical values. These 2 proteins are common acute phase reactants and further large scale evaluation with a larger number of patient's will be necessary to establish the possible clinical meaning of the existential changes of these proteins in vivax malaria patients. However, our proteomic analysis suggests the feasible values of some plasma proteins, such as haptoglobin and serum amyloid A, as associating factor candidates for vivax malaria.

Purpose. Natural herb has been used for traditional medicine for thousands of years. For this reason, alternative medicine methods affect to domestic animal field. The main purpose of this study was to confirm the regulated proteins after feed additive treatment. Methods. We used total thirty male pigs were used for this experiment. E. coli and Salmonella typhimurium, were used for promote enteritis. Animals were divided into a negative control group, positive control group and test group to determine the effect of an additive mixture on the changes in protein expression in serum. The pigs were given a food supplemented with a natural herbal additive containing immunoglobulin yolksac (IgY) at concentrations 1%. On the 1st week and after eight weeks of feeding, the serums were collected from each group. The changes in the serum proteome as a response to the herbal additive were examined using two-dimensional polyacrylamide gel electrophoresis. Results. A total of 14 differentially expressed protein spots were identified by comparing the protein profiles of the control and additive treated porcine serums. Finally, 7 proteins were detected by MALDI-TOF/MS. Moreover, the proteins detected are involved in a cholesterol control factor, inflammation regulator, Conclusion. These results support of the hypothesis that a natural herbal additive containing IgY can affect the immune regulation system and reduce the pathological process by microbial infections.

Male rats of Sprague-Dawley strain were subjected to low atmospheric pressures (500 and 300 mmHg)for an hour a day during 15 days. The serum protein patterns and the level of total serum proteins were determined at various time intervals during exposure. 1. When compared with control animals maintained at 760 mmHg, the low atmospheric pressure-exposed animal groups at 500 or 380 mmHg showed different changes in the serum protein patterns and the level of total serum proteins. 2. In the level of total serum preteins, a decrease resulted during the 1st day exposure of both groups, and slowly increased thereafter. From 5 to 15 days a higher steady state value than the control was obaserved. 3. In A/G ratio, the sera resulted in an increase in 1st day of both groups, and slowly decreased thereafter. From 5 to 15 days a lower steady state significantly than control value resulted. 4. Specifically, in the serum protein components, $\\beta$-globulin was increased during the experimental periods of both groups.

Background: Uroplakins have been widely investigated as potential markers in patients with bladder cancer because these proteins are specific to the urothelium. However, the role of uroplakin proteins in bladder cancer remains unknown. In this study, preoperative serum levels of uroplakin III were measured in patients with urothelial carcinoma of the urinary bladder and examined for possible association with clinicopathological features and clinical outcomes. Materials and Methods: This study included 52 bladder cancer patients at various stages and 28 healthy controls. Uroplakin III levels were detected in preoperative sera using an automated dot blot system and a micro-dot blot array. Results: There was a significant increase in serum uroplakin III levels in patients with bladder cancer as compared to healthy controls (p<0.05). In addition, serum uroplakin III levels were associated with muscle-invasive status, high grade and lymphovascular invasion (p<0.02). Log-rank tests indicated high serum uroplakin III to be significantly associated with cancer-specific mortality. Conclusions: Determination of serum uroplakin III level could be valuable for identifying patients with biologically aggressive bladder cancer.

Several authors reported that vegetable proteins cause to decrease serum cholesterol and reported the effect of limiting amino acid balance in dietary protein on the blood component. This study was designed to observe growth rate and blood component in 1% cholesterol-fed male rats intake pure isolated soy proteins and methionine for 4 weeks. The diets were supplemented with either 20% casein or isolated soy protein as dietary protein sources and methionine as limiting amino acid of isolated soy protein and casein protein. The results were as follows; 1) The body weight gain was the greatest in casein groups. 2) Serum total cholesterol concentration was significantly increased by casein groups and slightly decreased by isolated soy protein groups. 3) Serum HDL-cholesterol concentration was significantly increased by isolated soy protein groups than control group. 4) Serum total lipid and triglyceride concentrations were significantly decreased by isolated soy protein groups than control group. 5) Serum glucose concentration was significantly increased by isolated soy protein plus 0.8% methionine than control group. 6) Serum total protein and albumin concentrations were significantly increased by all experimental diets groups than control group. Especially, casein groups were the most increased in all experimental diets groups.
