  • Periodate-oxidized soluble starch and maltohexaose reacted with ${\alpha}-NH_2$ group of free amino acids and ${\varepsilon}-NH_2$ group of peptidyl lysine. The result shows that periodate-oxidized soluble starch and maltooligosaccharides reacted with protein and formed Schiff base between CHO group of oxidized sugar and ${\varepsilon}-NH_2$ group of surface lysine of protein molecule. Carbon and hydrogen composition of sweet potato ${\beta}-amylase$ modified with oxidized soluble starch increased and it's nitrogen composition decreased. Carbohydrate contents of sweet potato ${\beta}-amylase$ modified with oxidized soluble starch were 13.2% (pentamer), 13.4% (monomer), and with oxidized maltohexaose were 9.7% (pentamer), 9.3% (monomer) by $phenol-H_2SO_4$ method. Alpha-amino group of N-terminal, and ${\varepsilon}-NH_2$ group of lysine, of sweet potato ${\beta}-amylase$ were reacted with oxidized soluble starch by dinitrophenylation were 70% (pentamer), 73% (monomer) and 33% (pentamer), 26% (monomer), respectively, in comparison with native enzyme.

  • Objectives : This study was performed to examine the anti-allergic and anti-inflammatory effects of Jacho (Lithospermum erythrorhizon). Methods : Macrophage 264.7 cells were pretreatment, macrophage were incubated with lipopolysaccharide(LPS) 100ng/ml for 12h ($TNF-{\alpha}$, IL-6) or 24h ($IL-1\beta$, IL-10) and media collectred and $TNF-{\alpha}$, IL-6, $IL-1{\beta}$, and IL-10 concentrations in supernatants were each measured by enzyme-linked immunosorbent assay. Concentrations of Jacho used were 50, 100, 250, 500, and $1000{\mu}g/ml$, and hydrocortisones used were 10-8, 10-7, 10-6, 10-5, and 10-4M. Results : Jacho showed inhibitory effect on $TNF-{\alpha}$ LPS-stimulated macrophage 264.7. The inhibitory effect was most significant in $250{\mu}g/ml$, and was not in a dose-dependent manner as in the hydrocortisone group Jacho also showed inhibitory effect on IL-6 by LPS-stimulated macrophage 264.7. The inhibitory effect was most significant in $1000{\mu}g/mL$, and increased in a roughly dose-dependent manner. Jacho and hydrocortisone showed contrary effect on $IL-1\beta$. Jacho obviously increased the expression of $IL-1\beta$, in alt five concentrations, End at the fewest concentration $(50{\mu}g/ml)$ the level of $IL-1\beta$, was highest. On the other hand, hydrocortisone was observed to have inhibitory effect on $IL-1\beta$, in all five concentrations. IL-10 was obviously inhibited by Jacho and hydrocortisone respectively in a roughly dose-dependent manner. Conclusions : By the findings of this experiment. Jacho was observed to have anti-allergic and anti-inflammatory effects through inhibiting pro-inflammatory cytokine $TNF-{\alpha}$ and IL-6, and might be one of the effective therapeutic regimens for allergic diseases.

  • Soybean varieties derived from Korea are classified into four groups on the basis of their food types such as soybeans for vegetable, sprout, sauce and paste and soybeans with colored seed coat. This study was carried out to know the differences in storage protein concentrations among these four groups. There were differences in storage protein concentrations among four groups. In 7S protein, the $\alpha$'-and $\alpha$-subunit concentrations did not vary among four groups, while a $\beta$-subunit concentration greatly varied. 7S protein concentration was the highest(40.6%) in soybean for sauce and paste and the lowest(37.7%) in soybean for vegetable, while 11S protein concentration was the highest (62.3%) in soybean for vegetable and the lowest (59.4%) in soybean for sauce and paste. In view of the fact that 11S protein has much higher sulfur containing amino acids than 7S protein, it was shown the soybeans for vegetable may have higher nutrition value than other groups.

  • Objective To suggest rotation angles of fluoroscopy that can bypass the carotid sheath according to vertebral levels for cervical transforaminal epidural steroid injection (TFESI). Methods Patients who underwent cervical spine magnetic resonance imaging (MRI) from January 2009 to October 2017 were analyzed. In axial sections of cervical spine MRI, three angles to the vertical line (${\alpha}$, angle not to insult carotid sheath; ${\beta}$, angle for the conventional TFESI; ${\gamma}$, angle not to penetrate carotid artery) were measured. Results Alpha (${\alpha}$) angles tended to increase for upper cervical levels ($53.3^{\circ}$ in C6-7, $65.2^{\circ}$ in C5-6, $75.3^{\circ}$ in C4-5, $82.3^{\circ}$ in C3-4). Beta (${\beta}$) angles for conventional TFESI showed a constant value of $45^{\circ}$ to $47^{\circ}$ ($47.5^{\circ}$ in C6-7, $47.4^{\circ}$ in C5-6, $45.7^{\circ}$ in C4-5, $45.0^{\circ}$ in C3-4). Gamma (${\gamma}$) angles increased at higher cervical levels as did ${\alpha}$ angles ($25.2^{\circ}$ in C6-7, $33.6^{\circ}$ in C5-6, $43.0^{\circ}$ in C4-5, $56.2^{\circ}$ in C3-4). Conclusion The risk of causing injury by penetrating major vessels in the carotid sheath tends to increase at upper cervical levels. Therefore, prior to cervical TFESI, measuring the angle is necessary to avoid carotid vessels in the axial section of CT or MRI, thus contributing to a safer procedure.

  • Fourteen compounds were isolated from the n-BuOH fraction of the roots of Aralia cordata (syn. = A. continentalis). Through spectroscopic method, the chemical structures were elucidated as: caffeic acid (1), protocatechuic acid (2), thymidine (3), uridine (4), methyl-$\alpha$-D-fructofuranoside (5), a mixture (3 : 1) of $\beta$-D-fructopyranoside and $\beta$-D-fructofuranoside (6), 1-methyl 1,2,3,4-tetrahydro-$\beta$-carboline-3-carboxylic acid (7), methyl-$\beta$-D-fructofuranoside (8), sucrose (9), 5-caffeoylquinic acid (chlorogenic acid) (10), 3-caffeoylquinic acid (neochlorogenic acid) (11), 4-caffeoylquinic acid (cryptochlorogenic acid) (12), 3,5-di-O-caffeoylquinic acid (13), and 1-kestose [$\beta$-D-fructofuranosyl-($2{\rightarrow}1$)-$\beta$-D-fructofuranosyl-($2{\rightarrow}1$)-$\alpha$-D-glucopyranoside] (14). Among them, compounds 5, 7, 8, and 10 - 14 were isolated from this plant for the first time.

  • In this study, four compounds isolated from the red alga Laurencia snackeyi were evaluated for their potential anti-inflammatory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. These compounds were tested for their inhibitory effects on nitric oxide (NO) production in LPS-stimulated RAW 264.7 cells. Since $5{\beta}$-hydroxypalisadin B showed the best activity it was further tested for the production of prostaglandin-$E_2$ ($PGE_2$), expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), the release of pro-inflammatory cytokines tumor necrotic factor-alpha (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and interleukin-6 (IL-6). $5{\beta}$-Hydroxypalisadin B significantly reduced the $PGE_2$ release and suppressed the iNOS and COX-2 expression in LPS-stimulated RAW 264.7 cells. It also significantly reduced the release of pro-inflammatory cytokines TNF-${\alpha}$, IL-$1{\beta}$, and IL-6. These findings provide the first evidence of anti-inflammatory potential of $5{\beta}$-hydroxypalisadin B isolated from the red alga L. snackeyi and hence, it could be exploited as an active ingredient in pharmaceutical, nutraceutical and functional food applications.
