  • Bovine spastic paresis (BSP) is a neuromuscular disorder characterized by hypertension and stiffness of hindlimb. Two Korean native cattle (Hanwoo) calves developed BSP or BSP-like symptoms, and a tenotomy of superficial tendon of medial head and deep tendon of lateral head of gastrocnemius muscle was performed for treatment. A cast was applied postoperatively to prevent muscle rupture and was removed three weeks later. The prognosis was evaluated at 3 weeks, 6 and 18 months postoperatively. Neither calf showed any other postoperative sequelae. This is the first case study to report the diagnosis, treatment, and prognosis of BSP in Hanwoo.

  • We previously reported that the novel isoflavone-free peptide mixture (black soybean peptide, BSP) had several beneficial effects like antiobesity and hypotriglyceridemic effect. However, there are no reports for BSP on anti-hypertensive activity. BSP induced heme oxygenase-1 (HO-1) in HUVECs, thus investigated the HO-1-induced activity in HUVECs and the anti-hypertensive effects in SHR animal model. BSP significantly induced HO-1 expression both at transcriptional and protein levels in a time- and dose-dependent manner as measured by RT-PCR and Western blot analysis, respectively. These inductions were abolished by pretreatment of N-acetyl-cystein (NAC, 1~10 mM), but not by employing Tempol, a superoxide dismutase (SOD) mimetic (1~5 mM). As expected, enzymatic activity (~2 fold) determined by bilirubin formation assay and cGMP concentration (~6 fold) were significantly increased in BSP-treated cells. Based on the numerous evidences on the beneficial effects of HO-1 and our results, we investigated in vivo effects of BSP on the antihypertensive activity. The administration of BSP (1% in drinking water) significantly decreased mean blood pressure (BP) (from $218.6{\pm}6.99$ to $190.0{\pm}3.42$ mm Hg, p<0.01). This result indicates that BSP is strong inducer of HO-1 expression, which may be triggered by oxidative stress, and has anti-hypertensive activity.

  • The feasibility of incorporating black sesame powder (BSP) as a value-added food ingredient into bakery products was investigated using a cookie model system. BSP was incorporated into cookies at different content: 0%, 2%, 4%, 6%, and 8% (w/w) based on the total weight of wheat flour. The spread ratio and loss rate of cookies increased significantly with increasing levels of BSP (P<0.05). All color characteristics, including lightness ($L^*$), redness ($a^*$), and yellowness ($b^*$), decreased with a higher amount of BSP. Use of BSP significantly reduced the hardness of cookies (P<0.05), but no significant differences were found between the control and 2%, 4%, and 6% samples (P>0.05). 2,2-Diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging activities increased significantly (P<0.05). The consumer acceptance test indicated that addition of BSP up to 4% had a favorable effect on consumer preferences. Overall, cookies containing 4% BSP will add the advantage of the functional properties of BSP maintaining the consumer acceptability.

  • Purpose : To investigate the effects of 2-deoxy-D-glucose (2-DG) and quercetin (QCT) on gene expression of bone sialoprotein (BSP) and osteocalcin (OC) during the differentiation in irradiated MC3T3-E1 osteoblastic cells. Materials and Methods : When MC3T3-E1 osteoblastic cells had reached 70-80% confluence, cultures were transferred to a differentiating medium supplemented with 5 mM 2-DG or $10{\mu}M$ QCT, and then irradiated with 2, 4, 6, and 8 Gy. At various times after irradiation, the cells were analyzed for the synthesis of type I collagen, and expression of BSP and OC. Results : The synthesis of type I collagen in cells exposed to 2 Gy of radiation in the presence of 2-DG or QCT showed no significant difference compared with the control group within 15 days post-irradiation. When the cells were irradiated with 8 Gy, 2-DG facilitated the irradiation mediated decrease of type I collagen synthesis, whereas such decrease was inhibited by treating with QCT. During MC3T3-E1 osteoblastic cell differentiation, the mRNA expression of BSP and OC showed the peak value at 14 days and 21 days, respectively. 2-DG or QCT treatment alone decreased the level of BSP mRNA, but increased the OC mRNA level only at early time of differentiation (day 7). In the cells irradiated with 2, 4, 8 Gy, the mRNA expression of BSP and OC decreased at 7 days after the irradiation. The cells were treated with various dose of radiation in the presence of 2-DG or QCT, the mRNA level of both BSP and OC increased although this increase was observed at low dose of radiation (2 Gy) and at the early stage of differentiation. However, when the cells were exposed to 4, 6, or 8 Gy, the increase of BSP and OC mRNAs was detected only in cells co-incubated with QCT. Conclusion : This study demonstrates that 2-DG and QCT affect differently the expression of bone formation related factors, type I collagen, BSP, and OC in the irradiated MC3T3-E1 osteoblasic cells, according to the dose of radiation and the times of differentiation. Overall, the present findings suggest that 2-DG and QCT could have the regulatory roles as radiation-sensitizer and -protector, respectively.

  • In order to elucidate the effects of Panax Ginseng on the pharmacokinetics of sulfobromophthalein (BSP) in a pathological condition, patho-physiological changes, the kinetics of the disappearance of BSP from the blood and appearance in the bile were studied in rats. Group I , the control group, was produced by repeated injection of olive oil 0.1ml/100g under the skin of the back twice a week for 9 weeks. Group II , the Ginseng pretreated group, was produced by administration of Ginseng total saponin 200mg/kg/day P.O. for 10 days and subsequent injection of $CCl_4$ 0.1ml/100g under the skin of the back twice a week for 9 weeks. Group III , the chronically intoxicated group, was produced by repeated injection of $CCl_4$ 0.1ml/100g under the skin of the back twice a week for 9 weeks. The results obtained were summarized as follows; 1. The activities of GOT GPT of rat blood serum, body weight, and liver weight were affected by the pretreatment with Ginseng saponin. 2. The kinetics of the disappearance of BSP from the blood were affected by the pretreatment with Ginseng saponin. 3. The appearance of BSP in the bile was significantly affected by the pretreatment with Ginseng saponin.

  • Objective: To investigate dimensional changes in regional pharyngeal airway spaces after premolar extraction in bimaxillary skeletal protrusion (BSP) patients according to vertical skeletal pattern, and to further identify dentoskeletal risk factors to predict posttreatment pharyngeal changes. Methods: Fifty-five adults showing BSP treated with microimplant anchorage after four premolar extractions were included in this retrospective study. The subjects were divided into two groups according to the mandibular plane steepness: hyperdivergent (Frankfort horizontal plane to mandibular plane [FH-MP] ≥ 30) and nonhyperdivergent groups (FH-MP < 30). The control group consisted of 20 untreated adults with skeletal Class I normodivergent pattern and favorable profile. Treatment changes in cephalometric variables were evaluated and compared. The association between posttreatment changes in the dentoskeletal and upper airway variables were analyzed using linear regression analysis. Results: The BSP patients showed no significant decrease in the pharyngeal dimensions to the lower level in comparison with controls, except for middle airway space (MAS, p < 0.01). The upper airway variable representing greater decrease in the hyperdivergent group than in the nonhyperdivergent group was the MAS (p < 0.01). Posttreatment changes in FH-MP had negative correlation with changes in MAS (β = -0.42, p < 0.01) and inferior airway space (β = -0.52, p < 0.01) as a result of multivariable regression analysis adjusted for sagittal skeletal relationship. Conclusions: Decreased pharyngeal dimensions after treatment in BSP patients showed no significant difference from the normal range of pharyngeal dimensions. However, the glossopharyngeal airway space may be susceptible to treatment when vertical dimension increased in hyperdivergent BSP patients.

  • We synthesized three different derivatives of bis-spiropyran using simple organic reactions with high yields. BSP1, a derivative of bis-spiropyran having a connection at the position 6' and BSP2, a derivative of bis-spiropyran having a connection at the position 5 and BSP3, a derivative of bis-spiropyran containing a dithienylethene group between two spiropyran moieties were synthesized. The optical properties of BSPs were characterized. UV-Vis spectra showed that BSPs exhibit reversible photo-isomerization and the efficiency of photo-isomerization is highly dependent on the position of nitro group. BSPs having nitro group at para position of hydroxy group showed the higher efficiency of photo-isomerization that the one having nitro group at ortho position. The optical microscope images obtained under ultraviolet or visible light exposure demonstrated that the formation of nanorods can be reversibly controlled by optical signal.
