  • The efect of acute renal failure (ARF) on the pharmacokinetics o sulfobromophthalein (BSP) was investigated in order to elucidate if renal failure modifies the hepatic metabolism of drugs. ARF was induced by intravenous (iv) injection of uranyl nitrate (UN) to rats (5 mg/kg) five days before the experiment. Area under the plasma concentration-time curve (AUC)of BSP after portal vein (pv) injection increased by 2-fold and total body clearance ($CL_1$) decreased one half (p <0.01) in UN-induced ARF (UN-ARF) rate compared to the control rats. But the plasma disappearance of BSP after iv injection did not differ significantly between control and UN-ARF rats. Since BSP is excreted via the liver, $CL_1$ represented the approximate hepatic clearance of BSP. Therefore, the decrease in $CL_1$ represented the approximate hepatic clearance of BSP. Therefore, the decrease in $CL_1$ represents a decrease in hepatic intrinsic clearance ($CL_{int}$) for BSP since plasma free fraction ($f_p$) of BSP was not affected by UN-ARF. The content of hepatic cytoplasmic Y-protein, which catalyzes BSP-glutathione conjugation and limits the trasfer of BSP from blood to bile, increased significantly (p < 0.01), however its binding activity (BA) for BSP was decreased significantly (p <0.01) by UN-ARF. The decrease in $CL_{int}$might have some correlation with the changed characteristics of hepatic Y-protein, specifically its decreased BA for BSP.

  • The large-scale preparation method for black soybean peptide (BSP; about 70% less than 10,000 Da; highly enriched with glutamic acid, aspartic acid, and arginine) was developed, and its effect on weight reduction and lipid profiles in rats was investigated. Sprague-Dawleymale rats were assigned to four dietary groups (high-fat diets containing 0, 2, 6, and 10% BSP) and fed four weeks to examine the effects of BSP. During the experiment, food intake was measured every two days and body weight was monitored two times a week. After the supplementation of BSP, liver and adipose tissues (epididymal, retroperitoneal and perirenal adipose tissue) in the rats were weighted and the lipid profiles in serum, liver, and feces were analyzed. At the results of body weight gain, liver and epididymal adipose tissue weight, BSP groups were more decreased than HF group (0% BSP), with greater decreases at higher BSP levels. The same patterns were shown in lipid profiles of serum, as BSP was increased, triglyceride and total cholesterol concentration decreased. The serum HDL-cholesterol level was increased with increasing at BSP levels. Total cholesterol concentration of liver and feces were decreased and increased, respectively, as BSP increased. The results confirm that BSP is involved in reducing the body weight and the improvement of lipid composition in serum and liver of rats and that BSP can be applied in weight reduction in the food products industry.

  • In this paper, we present an efficient indoor rendering method using BSP(Binary Space Partitioning) and PVS(Potentially Visible Space) algorithms. The proposed method displays efficiently the objects by including the objects in the process of separating the number of BSP area, by jointly using BSP and PVS algorithms. Also, the screen which is checked by PVS from player's location is displayed. From the simulation, we can see that the proposed method improves the rendering speed because of processing the objects with the edges of BSP and PVS.

  • The aim of this study was to investigate the potential effects of extracts from silkworm (Bombyx mori L.) that was fermented with Bacillus subtilis KACC 91157 at the levels of 1%(v/w), 2.5%(v/w), and 5%(v/w) in alcohol-fed rats. Sprague-Dawley rats were divided into seven groups: normal group (N), alcohol treated group (C), silymarin treated group (PC, positive control), 5% silkworm powder treated group (SP5), 1% Bacillus subtilis-fermented silkworm powder treated group (BSP1), 2.5% BSP treated group (BSP2.5), and 5% BSP treated group (BSP5). The activities of AST, ALT, ALP, and LDH in the serum and the triglyceride concentrations in the liver and serum were increased by alcohol feeding but were reduced in the BSP5 group. In addition, the contents of total lipids, free fatty acids, and total cholesterol were increased in the alcohol-fed group but were reduced in the BSP5 group. The activities of ADH, ALDH and ADH, ALDH protein levels in the liver were increased in the BSP5 group. The TBARS contents in the liver, serum, liver mitochondria, and liver microsomes were slightly decreased in the BSP5 group compared to the C group. The hepatocytes in alcohol-fed rats contained numerous large droplets; however, BSP5 treatment prevented alcohol-induced lipid droplet accumulation in the hepatocytes. Based on these results, extracts from Bacillus subtilis-fermented silkworm (Bombyx mori L.) have significant potential for development into a functional health food that can improve alcoholic fatty liver conditions.

  • The aim of this study was to evaluate the difference of analytical methods for the pharmacokinetic study of bromosulfophthalein (BSP), an indicator of hepatobiliary function. The plasma and bile concentrations of BSP after intravenous administration were measured according to custom UV spectroscopy and HPLC, respectively. Plasma concentration of BSP measured by UV spectroscopy was similar to that measured by HPLC. There was no significant difference in the distribution volume, total body clearance, area under the curve and mean residence time of BSP between different analytical method groups. However, bile concentration of BSP measured by UV spectroscopy was overestimated compared with concentration measured by HPLC method. Biliary clearance of BSP obtained from UV spectroscopy method was almost 3 times higher than that obtained from HPLC method. Thus, a feasibility of UV spectroscopy method for high throughput pharmacokinetic evaluation of BSP was limited to the study based on the plasma concentration of BSP, not bile concentration.

  • The feasibility of incorporating black sesame powder (BSP) as a value-added food ingredient in convenient food products, using a model system of yanggaeng, was investigated. BSP was incorporated into yanggaeng at 0, 3, 6, 9, and 12% (w/w) weight amounts based on the total weight of cooked white bean and BSP. pH increased significantly with increasing levels of BSP added (p<0.05). In terms of color, lightness and yellowness decreased significantly but redness increased (p<0.05) with increasing levels of BSP. Hardness also increased significantly with higher amounts of BSP in the formulation (p<0.05). Total polyphenol content and 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity significantly increased as the BSP concentration increased in the formulation (p<0.05). Finally, the consumer acceptance test indicated that the highest levels of BSP incorporation (12%, w/w) had a considerable adverse effect on consumer preferences in all attributes. In contrast, yanggaengs with moderate levels of BSP (6%, w/w) are recommended (based on overall preference score) for taking advantage of the functional properties of BSP without sacrificing consumer acceptability.

  • The purpose of this paper is to design Conformance Test Suite for BSP(Biometric Service Provider) based on BioAPI(Biometric Application Programming Interface) v2.0. The proposed BioAPI Conformance Test Suite enables users to test BSP with framework independently. A test scheduling tool has been embodied to use Test Assertion in the form of XML. In order to demonstrate the performance of the Conformance Test Suite, the experiment was performed by using both verification and identification BSPs. As the results of this experiment, we were able to determinate whether BSPs based on BioAPI v2.0 satisfied standard requirements or not.

  • Effects of Ssang Wha Tang (SWT), a blended Chinese traditional medicine, on the pharmacokinetics of sulfobromophthalein (BSP) were studied in the rats. BSP was administered via portal vein to the control and the SWT-treated rats. The in vitro distribution of BSP to blood cells and the hemato-physiological conditions, liver weight, GOT. GPT activity were also examined. The systemic clearance $(CL_s)$ of BSP was increased with the administration of SWT, but no significant differences were observed in the liver weight and in vitro distribution of BSP to blood cells. These results suggest that the intrinsic clearance of free BSP of the liver is increased with the administration of SWT in the rats.

  • The quality characteristics of the bread prepared with black soybean powder(BSP) were evaluated. Breads were prepared by the addition of 0, 5, 10, 15, and 20% of BSP to the basic formulation. The pH's of dough with BSP were ranged from 5.13 to 5.77 and that of the control was 5.43. The volume of dough, loaf volume and loaf volume index of the bread with 5%-BSP was the highest. The peak viscosity of the doughs with BSP (200~545 BU) measured by the Amylograph were lower than that of the control (1077 BU). Color $L^{*}$ value of the bread crust and crumb with BSP decreased, and color $a^{*}$ values of the bread crumb with BSP increased, but $a^{*}$ and $b^{*}$ values of the crust with BSP decreased. The hardness, cohesiveness, springiness, and gumminess increased as the concentration of BSP increased. Degree of retrogradations(2.60~4.07) of the bread with BSP was lower than that(6.00) of the control after 48 hrs. From the result of the sensory evaluation, the overall quality score of the bread with 5%-BSP, 4.37, was the highest among samples compared with.ith.ith.
