Co-intake-related interactive-synergistic influence of artemether-lumefantrine, AL and monosodium glutamate, MSG that separately mediated oxidative stress could be significant on the kidney actively involved in xenobiotic detoxification and elimination. Thus, influence of AL on rats’ kidney histomorphology and antioxidant bio-indicators following MSG-challenge was assessed. For 7 days, thirty rats (n = 5) were respectively exposed to vehicle (distilled water), therapeutic AL (TAL), high AL (HAL), MSG, MSG plus TAL or MSG plus HAL. Significant (P<0.05) results comparison showed highest and least (P<0.05) albumin concentration (Mg/dl) in TAL-fed (3.76±0.33) and MSG-fed (1.88±0.70), rats. Total protein concentration (Mg/dl) in MSG-fed (4.04±2.04) and HAL-fed (4.76±1.92), rats lowered markedly. Highest glutathione peroxidase activity (IU/L) in TAL-fed (30.74±12.46) lowered in MSG plus HAL-fed (20.11±6.08) and MSG-fed (20.33±4.85), rats. Catalase activity (IU/L) in control was highest (4.89 ± 0.26) but least (2.58 ± 1.06) in MSG-fed rats. Zinc and Magnesium concentration (Mg/dl) was respectively highest (58.99±5.10) and least (3.48±0.31) in MSG plus HAL-fed but least (18.80±7.77) and highest (4.38±1.67) in MSG-fed, rats. Malondialdehyde concentration (µmol/ml) in MSG plus HAL-fed rats (4.04±0.67) was highest (P<0.05) and least (P<0.05) in HAL-fed rats (1.18±0.11). Differences in superoxide dismutase activity (IU/L) were, however, non-significant (P>0.05).Rats’ kidney photomicrographs (H&E × 400) revealed normal histo-architecture in control but varied degree of fibroplasias (TAL- ,HAL- and MSG plus TAL-fed) and necrosis with infiltrations (MSG plus HAL-and MSG-fed), rats. These demonstrated MSG-related adversity and significant modulation response of TAL, unlike HAL, on the rats’ kidney histology and studied antioxidant response bio-indicators.

Abstract Abstract 1738 Sipuleucel-T is an autologous cellular immunotherapy for the treatment of asymptomatic or minimally symptomatic metastatic castrate resistant prostate cancer. Sipuleucel-T consists of autologous peripheral blood mononuclear cells (PBMCs), including antigen presenting cells (APCs), that have been activated with a recombinant human protein, PAP-GM-CSF (prostatic acid phosphatase [PAP] linked to granulocyte-macrophage colony-stimulating factor [GM-CSF]). It is prepared from cells collected by leukaphereses at Weeks 0, 2, and 4 and infused approximately 3 days following each leukapheresis. In the IMPACT study, 512 patients were randomized (2:1) to sipuleucel-T or control (non-activated autologous PBMCs). Serum samples were collected at Baseline and Weeks 6, 14, and 26, and were analyzed for routine clinical chemistry tests in a comprehensive metabolic panel, which included total protein and albumin. In selected samples, serum protein electrophoresis (SPEP) and densitometry were performed using the Sebia automated electrophoresis system. We observed elevated total protein at Weeks 6 and 14 in sipuleucel-T patients only. At Week 6, 10.0% (28/279) of sipuleucel-T patients with a normal baseline total protein concentration had an elevated total protein concentration (upper limit of normal [ULN] = 7.9 to 8.5 g/dL, depending on age) compared with 0% (0/140) of control patients. At Week 14, 10.4% (19/183) of sipuleucel-T patients with a normal baseline total protein had an elevated total protein compared with 0% (0/86) of control patients. Albumin levels were not elevated at Week 6 following treatment (0.4% ½84 of sipuleucel-T patients with a normal baseline albumin concentration had increases in post-treatment serum albumin), indicating that the changes in total protein were due to elevations in serum globulin. In sipuleucel-T patients, there was a positive correlation between the maximum globulin protein elevations (total protein minus albumin) and the magnitude of antibody titers to PAP-GM-CSF at Week 6 (n = 126; P = 0.001) and Week 14 (n = 85; P = 0.002). Samples from sipuleucel-T patients for whom both a baseline and post-treatment sample were available and who fell within the upper 10th percentile of the total protein change (n = 13) were evaluated by SPEP. All of these patients had increased gamma globulin compared with baseline. Nine patients (69.2%) developed gamma globulin above the upper limit of normal (i.e., > 1.5 g/dL) which was not present at baseline. A correlation between gamma globulin elevations and antibody titers to PAP-GM-CSF in these patients (n = 9) was observed at Week 6 (r = 0.664, P = 0.051). These data demonstrate that elevated gamma globulin levels can develop following treatment with sipuleucel-T and were associated with the development of an antigen-specific humoral response.

Abstract We measured the concentrations of total protein and albumin in sera of 281 well-fed premature infants, gestational ages 22-36 weeks, and calculated reference values from the 10th to 90th percentiles. The mean serum albumin concentration (27.6 +/- 4.4 g/L, mean +/- SD) and total protein concentration (49.2 +/- 6.7 g/L) at a postnatal age of 14.5 days were lower than reference values for full-term infants. We detected a significant positive correlation between albumin concentration and gestational age (r = 0.34, p less than 0.01) and total protein concentration and gestational age (r = 0.43, p less than 0.01). Even though albumin values were low, generalized edema was not present. We conclude that values for total protein and albumin in the preterm infant are lower than in the full-term infant but are an expected physiological response to premature birth.

25 Hydroxycholecalciferol

Background: Burned patients have an increased need for vitamin D supply related to the maintenance of calcium–phosphate homeostasis and the regulation of cell proliferation/differentiation. This study aimed to analyze the concentration of 25-hydroxycholecalciferol and its relationship with severe condition after burn injury. Methods: 126 patients were enrolled in the study. Patients were qualified due to thermal burns—over 10% of total body surface area. On the day of admission, the following parameters were assessed: 25-hydroxycholecalciferol concentration, total protein concentration, albumin concentration, aspartate transaminase activity, alanine transaminase activity, albumin concentration, creatinine concentration, c-reactive protein concentration, procalcitonin concentration, and interleukin-6 concentration. Results: Almost all patients (92%) in the study group had an improper level of vitamin D (<30 ng/mL), with the average of 11.6 ± 10.7 ng/mL; 17.5% of patients had levels of vitamin D below the limit of determination—under 3 ng/mL. The study showed that there are several factors which correlated with vitamin D concentration during the acute phase of burn injury, including: total protein (r = 0.42, p < 0.01), albumin, (r = 0.62, p < 0.01), percentage of body burns (r = 0.36, p < 0.05), aspartate aminotransferase (r = 0.21, p < 0.05), and c-reactive protein (r = 0.22, p < 0.05). We did not find any significant correlation between vitamin D concentration and body mass index. Conclusions: The burn injury has an enormous impact on the metabolism and the risk factors of the deficiency for the general population (BMI) have an effect on burned patients. Our study showed that concentration of 25-hydroxycholecalciferol is strongly correlated with serum albumin level, even more than total burn surface area and burn degrees as expected. We suspect that increased supplementation of vitamin D should be based on albumin level and last until albumin levels are balanced.

Animal preparations for microscopy often require a superfusate solution to cover surgically exposed tissue. There are few, if any, data concerning the effects of this solution on extravascular protein concentration and hydration. The effect of superfusion on mesenteric tissue in anesthetized male Sprague-Dawley rats was studied. Tissue samples were taken from nonsuperfused and superfused tissue and analyzed for hydration, albumin, and transferrin content. The mesenteric tissue interstitial matrix was rapidly altered by normal saline superfusate. After superfusion, there was a decrease (P < 0.01) in tissue albumin concentration from 1.17 +/- 0.27 to 0.10 +/- 0.08 g/dl (n = 9). Tissue hydration increased from 4.98 +/- 0.8 micrograms water/microgram dry wt in controls to 7.38 +/- 1.2 micrograms water/micrograms dry wt after superfusion. When a range of superfusate albumin concentrations was used (0, 1, 2, and 3 g/dl), tissue albumin concentration changed 0.59 +/- 0.09 g/dl for each gram per deciliter change in superfusate concentration (P < 0.0001). The large changes in interstitial matrix protein content and hydration suggest that superfusate solution effects need to be considered in microvascular protein transport experiments.

Protein Assays

The standard curve of a typical colorimetric assay for total protein is often nonlinear and dependent on the albumin fraction of the protein standard. We developed a simple mathematical transformation to make the standard curve linear and a computational method to correct for differences in albumin concentrations among the samples. This method uses data from total protein assays on two sets of standards (albumin and gamma globulin) and provides accurate measures of total protein over the full range of albumin fractions. Comparison of this two-standard method with the a method that uses only albumin as a standard shows that this method prevents physiologically significant overestimations in total protein concentration and calculated protein osmotic pressure differences in the lungs.

This study aimed to determine the effects of red fruit (Pandanus conoideus Lam) oil on MDA levels and spermatozoa quality in mice (Mus musculus) exposed to MSG. The quality includes motility, viability, concentration, and morphology of spermatozoa. This experimental study used randomized post-test only control group design. The subjects of this study were 25 mice (Mus musculus), divided into 5 groups (5 mice per group). K- group received distilled water for 35 days. K+ group received 4 mg/g BW MSG for 21 days. P1, P2, and P3 treatment groups received 4 mg/g BW MSG for 21 days and 0.02; 0.04; 0.08 ml/g BW red fruit oil, respectively, from day 22 to 35. The results showed that mean spermatozoa morphology in K-, K+, P1, P2, P3 groups were as follows: 0.86; 0.56; 0.67; 0.61; and 0.87 (%). The spermatozoa concentrations were sequentially as follows: 21; 10; 15; 32,8,19 (107 cells/ml). The spermatozoa's vitalities were as follows: 0,64; 0,14; 0,24; P2: 0.36; 0.68 (%). MDA levels were respectively: 0.29; 0.60; 0.35; 0.23; and 0.19 (nm). As a conclusion, testicular MDA levels in mice exposed to MSG and given with red fruit oil were lower than those in mice exposed to MSG without receiving red fruit oil. The quality of spermatozoa in mice exposed to MSG and receiving red fruit oil was higher than that of mice exposed to MSG without being given with red fruit oil.

There is no standard as to treatment of anthracycline chemotherapy complications. The reduction of cytotoxic drugs toxicity without weakening of their antitumor action remains relevant. The extracellular matrix which key component is fibronectin is present in all tissues and it continuously undergoes controlled remodeling. So, the purpose of our work was to study the level of fibronectin in the experimental model of doxorubicin-induced cardiomyopathy and effects of this cytostatic and its co-administration with antioxidants of different nature.The level of fibronectin was measured by ELISA using monospecific antibodies against fibronectin (Sigma, USA), secondary anti-IgG labeled with horseradish peroxidase (Sigma, USA) and fibronectin standard (Sigma, USA). The study was conducted on Wistar male rats with weight of 210 ± 50 g which were divided into 4 groups by 8 animals in each group: 1 – control, rats receiving saline i/p; 2 – doxorubicin 1 mg/kg i/p once a week during 4 weeks; 3 – doxorubicin by the same scheme plus 1% 2-oxoglutarate in drinking water during 4 weeks;4 – doxorubicin by the same scheme and korvitin injection 30 min before doxorubicin application once a week during 4 weeks. Obtained data indicate the effect of doxorubicin to decrease in index mass heart in 38% of animals compared to control animals; decrease in total protein concentration by 8% (Р < 0,05) and increase of the level of fibronectin by 67% (P < 0,001) in blood plasma of rats and decrease in the level of fibronectin in the heart extract by 19% (Р < 0,05) under development of doxorubicin-induced cardiotoxicity. Increased fibronectin concentration in blood plasma had strong correlation with decreased total protein concentration in blood (r=0,80) and heart extract (r=0,59) in rats with doxorubicin-induced cardiomiophaty indicating the sensitive reaction of fibronectin to development of metabolic disorders under doxorubicin influence.
