  • This research has been conducted to develop the best recipe for brown sauce containing freeze-dried Salicornia powder. For this purpose, we made brown sauces with different contents of freeze-dried Salicornia powder and performed physico-chemical characteristic and sensory test. The highest salinity of freeze-dried Salicornia powder was 0.15% when 1% freeze-dried Salicornia powder was added to distilled water, SP1. The highest brightness of brown sauce was achieved with 1.2% freeze-dried Salicornia powder and was 45.29 with BSP12. More powder led to significant increases of the samples(p<0.001) in salinity and brightness. DPPH radical scavenging increased with greater freeze-dried Salicornia powder. Taste was highest at 6.36 with 0.6% powder and there was no significant difference compared to BSP6 and BSP9. Based on these findings, it was concluded that the brown sauce with Salicornia has antioxidative characteristics and the best salinity is achieved with 0.6% freeze-dried Salicornia powder. Salicornia had enough salinity to substitute salt to a certain degree and improved the quality of brown sauce in terms of the sensory test.

  • Background: Brucella infection induces brucellosis, a zoonotic disease. The intracellular circulation process and virulence of Brucella mainly depend on its type IV secretion system (T4SS) expressing secretory effectors. Secreted protein BspJ is a nucleomodulin of Brucella that invades the host cell nucleus. BspJ mediates host energy synthesis and apoptosis through interaction with proteins. However, the mechanism of BspJ as it affects the intracellular survival of Brucella remains to be clarified. Objectives: To verify the functions of nucleomodulin BspJ in Brucella's intracellular infection cycles. Methods: Constructed Brucella abortus BspJ gene deletion strain (B. abortus ∆BspJ) and complement strain (B. abortus pBspJ) and studied their roles in the proliferation of Brucella both in vivo and in vitro. Results: BspJ gene deletion reduced the survival and intracellular proliferation of Brucella at the replicating Brucella-containing vacuoles (rBCV) stage. Compared with the parent strain, the colonization ability of the bacteria in mice was significantly reduced, causing less inflammatory infiltration and pathological damage. We also found that the knockout of BspJ altered the secretion of cytokines (interleukin [IL]-6, IL-1β, IL-10, tumor necrosis factor-α, interferon-γ) in host cells and in mice to affect the intracellular survival of Brucella. Conclusions: BspJ is extremely important for the circulatory proliferation of Brucella in the host, and it may be involved in a previously unknown mechanism of Brucella's intracellular survival.

  • GATA4 has been reported to act as a negative regulator in osteoblast differentiation by inhibiting the Dlx5 transactivation of Runx2 via the attenuation of the binding ability of Dlx5 to the Runx2 promoter region. Here, we determine the role of GATA4 in the regulation of bone sialoprotein (Bsp) in osteoblasts. We observed that the overexpression of Runx2 or Sox9 induced the Bsp expression in osteoblastic cells. Silencing GATA4 further enhanced the Runx2- and Sox9-mediated Bsp promoter activity, whereas GATA4 overexpression down-regulated Bsp promoter activity mediated by Runx2 and Sox9. GATA4 also interacted with Runx2 and Sox9, by attenuating the binding ability of Runx2 and Sox9 to the Bsp promoter region. Our data suggest that GATA4 acts as a negative regulator of Bsp expression in osteoblasts.

  • Effects of Ssang Wha Tang (SWT), a blended Chinease traditional medicine, on the pharmacokinetics of sulfobromophthalein (BSP) in the rats of hepatic failure induced by carbon tetrachloride were examined. The disposition of plasma BSP in carbon tetrachloride-treated rats (Group I) and in carbon tetrachloride+SWT-treated rats (Group II) followed a three-compartment model, while those in control group followed two-compartment model. GOT, GPT level and some pharmacokinetic paramiters like plasma clearance but except distribution volume (Vdss) recovered in Group II compared to Group I. Therefore, SWT seemed to have an apparent restoring effect of hepatic function damaged by carbon tetrachloride treatment. From the fact that Vdss of BSP in Group II was considered as an one of the probable mechanisms. More intensive increase in BSP-free fraction ($f_p$) in Group II than that in Group I might also explain the increases of BSP clearance and Vdss in Group II compared to Group I. Assuming no changes in hepatic plasma flow(Q) in each group, hepatic intrinsic clearance($CL^h_{int}$) decreased in Group I did not recovered not at all in Group II. Therefore SWT seemed not to have any restoring effect of true hepaticfunction to biotransform and excrete BSP, and the apparent restoring effect of SWT might be due only to the replacement of BSP-plasma protein binding. Whether $f_p$ is actually higer in Group II than in Group I, and Q is constant in each group are being examined in our laboratory. The changes of Q, which might lead to another conculusions, also should be taken into consideration to clarify the apparent hepatorestoring effect of SWT.

  • Objective: To compare the effects of bone suppression imaging using deep learning (BSp-DL) based on a generative adversarial network (GAN) and bone subtraction imaging using a dual energy technique (BSt-DE) on radiologists' performance for pulmonary nodule detection on chest radiographs (CXRs). Materials and Methods: A total of 111 adults, including 49 patients with 83 pulmonary nodules, who underwent both CXR using the dual energy technique and chest CT, were enrolled. Using CT as a reference, two independent radiologists evaluated CXR images for the presence or absence of pulmonary nodules in three reading sessions (standard CXR, BSt-DE CXR, and BSp-DL CXR). Person-wise and nodule-wise performances were assessed using receiver-operating characteristic (ROC) and alternative free-response ROC (AFROC) curve analyses, respectively. Subgroup analyses based on nodule size, location, and the presence of overlapping bones were performed. Results: BSt-DE with an area under the AFROC curve (AUAFROC) of 0.996 and 0.976 for readers 1 and 2, respectively, and BSp-DL with AUAFROC of 0.981 and 0.958, respectively, showed better nodule-wise performance than standard CXR (AUAFROC of 0.907 and 0.808, respectively; p ≤ 0.005). In the person-wise analysis, BSp-DL with an area under the ROC curve (AUROC) of 0.984 and 0.931 for readers 1 and 2, respectively, showed better performance than standard CXR (AUROC of 0.915 and 0.798, respectively; p ≤ 0.011) and comparable performance to BSt-DE (AUROC of 0.988 and 0.974; p ≥ 0.064). BSt-DE and BSp-DL were superior to standard CXR for detecting nodules overlapping with bones (p < 0.017) or in the upper/middle lung zone (p < 0.017). BSt-DE was superior (p < 0.017) to BSp-DL in detecting peripheral and sub-centimeter nodules. Conclusion: BSp-DL (GAN-based bone suppression) showed comparable performance to BSt-DE and can improve radiologists' performance in detecting pulmonary nodules on CXRs. Nevertheless, for better delineation of small and peripheral nodules, further technical improvements are required.

  • That different mechanisms are involved in the secretory processes by the liver and the kidney of various dyes has been indicated by Sporter (1959), Kim and Hong (1963). Andrews (1958). suggested that a striking difference in the dye-secretory mechanism existed even in the same organ from species to species. Hence, the attempt has been made to study in the rabbit the secretory processes by the live. and the kidney of either phenol red (PSP), bromsulfalein (BSP) or green in the presence of Na-acetate, Na-taurocholate, P-Aminohippurate (PAH) or Benemid. In 37 rabbits, weighing about 2kg., anesthetized with ether, a dye was administered in such 8 manner that the plasma concentration was kept at a relatively constant level throughout the whole experimental period. Hepatic bile sad urine samples were quantitatively collected through the canulae which were previously inserted into the common bile duct (with the cystic duct ligated) and the urinary bladder, respectively, while arterial samples were taken from a femoral artery. After 50 min from the onset of dye administration, these samples were obtained every 10 mit for a period of 40 min. This was followed by the administration of either Na-acetate, Na-tauro-cholate, PAH or Benemid with a repetition of the same sample collecting procedures just stated. The results may be summarized as follows: 1) Na·acetate augmented urinary clearance of PSP by nearly 300 per cent, but lowered urinary BSP clearance by about 50 per cent. It enhanced biliary BSP clearance by 40% and had no effect on biliary psp clearance. 2) Na-taurocholate lowered biliary and urinary clearance of PSP by 10 per cent and 30 per cent respectively, and had no effect on both biliary and urinary clearance of BSP. 3) PAH lowered both biliary and urinary excretion of BSP and PSP, while it lowered the biliary excretion of indocyanine green which was excreted only in the bile. 4) Benemid suppressed BSP excretion by the liver and the kidney. 5) raper chromatographic analysis of PSP and of BSP in the bile and urine samples gave the following results: a) PSP Ivas excreted in the urine and bile only in free forms, and no modification in the excretory pattern was brought about by Na-taurocholate. b) BSP was excreted in the urine in 4 different conjugated froms and in the bile in both 3 different conjugated forms and in a free form. Na-taurocholate modified the excretory pattern of the urinary BSP.

  • Nuclear factor I (NFI) exists in the odontoblast and osteoblast. NFI-C null mice demonstrated aberrant odontoblast differentiation, abnormal dentin formation, and molar lacking roots. The purpose of this study was to examine phenotype of the aberrant odontoblast in NFI-C null mice and to evaluate the expression of DSPP and BSP mRNAs in NFI-C null mice with in-situ hybridization. The results were as follows: 1. In the NFI-C (-/-) mice, the crown dentin of molar showed normally formation, but there was no root dentin. 2. In the NFI-C (-/-) mice, the labial dentin of mandibular incisors showed relatively a lot of dentin formation, but the lingual dentin showed defect. 3. In the NFI-C (-/-) mice, the odontoblast of mandibular incisors revealed abnormal shape and trapped in osteodentin-like mineralized tissue. 4. In the NFI-C (-/-) mice, the odontoblast in the crown dentin of molars showed strong expression of DSPP, the odontoblast in the root dentin of molars was not expression of DSPP. In the NFI-C (-/-) mice the odontoblast in the mandibular incisors showed weekly expression of DSPP 5. In the wild mice, the odontoblasts of mandibular incisors were not expression of BSP, but in the NFI-C (-/ -) mice the odontoblast of mandibular incisors showed strong expression of BSP These results suggest that odontoblast in the NFI-C (-/-) mice changes the phenotype into osteoblast.

  • The aim of this study was to investigate the potential effects of extracts from silkworm Bombyx mori L. fermented with Bacillus subtilis KACC 91157 at levels of 5%(v/w) and 10%(v/w) in Sprague-Dawley rats intoxicated with 1%(w/w) orotic acid (OA) for 10 days. The rats were divided into a normal group (N), a control group (C: OA), and treatment groups (SP10: OA + 10% extracts from B. mori L.; BSP5: OA + 5% extracts from B. mori L. fermented with B. subtilis KACC 91157; BSP10: OA + 10% extracts from B. mori L. fermented with B. subtilis KACC 91157). Serum activities of aspartate aminotransferase (AST), alanine transferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) increased following OA feeding, but the rise was slightly reduced by administration of BSP10. The total lipid, free fatty acid, phospholipid, total cholesterol, and triglyceride contents in serum were significantly lower in the OA treatment groups than in the N group. However, the contents slightly increased following the administration of BSP10. Glutathione concentrations in liver and serum were reduced in the OA-induced fatty liver, but they increased following the administration of BSP10. Hepatocytes in the OA-induced fatty liver contained numerous large droplets. However, SP10, BSP5, and BSP10 feeding prevented OA-induced lipid droplet accumulation in hepatocytes. Accordingly, extracts from silkworm powder fermented with B. subtilis could be an ideal material as a dietary supplement in healthy functional foods to improve the effects of fatty liver.

  • Antiobesity, hypotriglyceridemic and antihypertensive activities of isoflavone-free peptide mixture (black soybean peptide, BSP) were reported in our previous experiments. In the present study, angiotensin converting enzyme inhibitory (ACEi) activity was decreased in the aorta tissues of spontaneously hypertensive rats (SHRs) treated with BSP (1% in drink water) for 4 weeks, but not in serum. BSP administration significantly decreased ACE activity by 17.5% (from $33.2{\pm}4.5$ to $27.4{\pm}1.96$ mUnit/mg, p=0.0013) in aorta tissue hydrolysate. BSP treatment also decreased significantly mean blood pressure (BP) (from $213.0{\pm}16.96$ to $184.0{\pm}6.53$ mmHg, p<0.0001) as expected. These results indicate that BSP has antihypertensive activity as well as ACEi activity.
