  • This study was carried out to investigate the quality characteristics and antioxidant activities of Rehmanniae radix (Rehmannia glutinosa Libosch. var. purpurea Makino) freeze-dried powder (RRP) and Rehmanniae radix preparata powder (RRPP). Under the Hunter color system, redness was higher and lightness/yellowness lower in RRPP, compared to RRP. The reducing sugar contents of RRP and RRPP were 0.8% and 6.0%, respectively (p<0.05). The pH was lower in the RRPP (RRP: 6.71, RRPP: 4.23). The amount of catalpol amount in RRPP (47.20 mg/mL) was lower than RRP (144.90 mg/mL). RRPP contained high amounts of 5-HMF (5-hydroxymethyl-2-furaldehyde, 47,231 mg/mL), but 5-HMF was not detected in RRP. Total phenol contents of RRP and RRPP were 2.10 mg/mL and 3.66 mg/mL, respectively. FRAP values of RRP and RRPP were 0.51 mg/mL and 1.99 mg/mL, respectively. The antioxidant activities by DPPH (1,1-diphenyl-2-picryl hydrazyl) and hydroxyl radical scavenging activity of RRPP were much higher than RRP. Based on these results, RRPP is a good candidate for food processing in terms for its physicochemical and antioxidative activities.

  • The purpose of this study was to evaluate the quality characteristics and antioxidant activities of noodles added with Rehmanniae Radix Preparata powder (RP). Wheat flour noodles were prepared with four levels of RP (0, 2.5, 5, and 7.5%). Moisture absorption of RP added noodles was somewhat greater than that of control. The turbidity of RP noodles decreased according to addition of RP. Hunter L (lightness) and b (yellowness) values of RP added noodles decreased according to addition of RP amount. Textural properties (measured by a texture analyzer), hardness, and springiness of RP noodles up to 5% were not significantly different from those of control. Antioxidant activity of RP added noodles increased according to addition of RP: $IC_{50}$ values of DPPH radical scavenging activity for raw noodles was 3.77 mg/g, whereas values of raw noodles with RP 2.5 and 7.5% were 3.69 mg/g and 2.47 mg/g, respectively. Polyphenol content increased according to addition of RP. Amylogram showed that RP addition increased initial gelatinization temperature, decreased breakdown, and reduced setback and consistency, which indicates protection against retrogradation. The sensory preference test revealed that cooked noodles with added 2.5% RP showed the highest scores for color, odor, taste, and overall preference. It is suggested that RP up to 2.5% could be substituted for wheat flour to improve noodle quality.

  • This study was investigated the quality characteristics and antioxidant activities of the Rehmanniae radix (Rehmannia glutinosa Libosch. var. purpurea Makino) paste (RRP) and Rehmanniae radix preparata extract (RRPP). RRP and RRPP were made from vacuum concentrates of hot water extracts. The sugar contents of RRP and RRPP were 65.3 and 72.0$^{\circ}Brix$, respectively, whereas the reducing sugar contents were 2.4% and 44.9%. The pH level was lowest in the RRPP. The DPPH and hydroxyl radical scavenging activity of RRPP were much higher than those of RRP. Total phenol contents of RRP and RRPP were 2.15 mg/mL and 12.36 mg/mL, respectively. FRAP values of RRP and RRPP were 0.55 mg/mL and 2.02 mg/mL, respectively. Based on these results, it can be concluded that RRPP was the most appropriate in terms of both physicochemical and antioxidative activities.

  • 한의학에 있어서 음양의 조절은 매우 중요하다. 숙지황은 음허를 치료하는 주약이며, 부자는 양허를 치료하는 주약이다. 한의학에서 신성고혈압의 발생은 음허와 관련이 있다고 하였다. 본 연구는 실험적 신성고혈압과 자연발증고혈압 백서에 숙지황과 부자 전탕액을 투여 후 혈압의 변동과 혈장 renin 활성도, aldosterone 및 심방이뇨호르몬 (atrial natriuretic hormone)의 변동을 관찰하였다. 숙지황 투여후 실험적 신성고혈압 백서의 혈압은 감소하였다. 부자 전탕액 투여 후 자연발증고혈압 백서의 혈압 상승이 억제되었다. 숙지황 및 부자 전탕액 투여 후 자연발증고혈압 백서의 혈장 renin 활성도는 감소하였다. 부자 전탕액 투여 후 신성고혈압 백서의 혈장 ANP 농도는 감소하였다. 부자 전탕액의 혈압강하 작용은 ANP 및 aldosterone 농도의 변동과 관련이 있다고 사료된다.

  • The purpose of this study, which was processed from March $22^{nd}$ to April $9^{th}$ of 2010, was to figure out recognition, well-formed instructions, and Practical application about dental hygiene devices based on the dental health characteristics of 350 adults who dwell in Busan and Gyeongnam regions. Also, this study recommended the adults to use dental hygiene devices and provided such devices to help individuals take care of their dental health at home. The collected data was statistically processed with a statistics SPSS (Statistical Packages for Social Science 14.0. SPSS Inc. USA) program. First of all, in order to demonstrate the characteristics of the sample population statistics and that of the descriptive data, frequency analysis was performed and to find out the relationship between variations of the dental health, Chi-squared test through Crosstabs was operated. According to the study, recognition and Practical application of dental hygiene devices were very low. Therefore, public announcement about necessity and effectiveness of such devices should be reinforced nationwide and instructions on choosing the right device and using of the dental hygiene devices based on patients' conditions by dental hygienic human efforts gathered from dental health organization should be carried out.

  • Rehmanniae Radix Preparata is manufactured with Rehmanniae Radix accoding to KP V. For quality control of Rehmanniae Radix Preparata, its standard component is required. The methanol extracts of Rehmanniae Radix crudus, Rehmanniae Radix, Rehmanniae Radix preparata were divided into the three groups of ether, butanol and aqueous fraction by liquid-liquid separation. In the comparative TLC of ether fraction, the characteristic component of Rehmanniae Radix preparata was found. The ether fraction was evaporated and separated on the silica gel column with chloroform-methanol and further separated on the preparative silica gel TLC with chloroform-methanol-water. The component was illucidated as 5-(hydroxymethyl)-2-furancarboxaldehyde(5-HMF). 5-HMF was not found in Rehmanniae Radix crudus and found in Rehmanniae radix in much less Quantities than Rehmanniae Radix Preparata.

  • We investigated the biological activities on ethanol extracts of R. glutinosa and R. glutinosa Preparata. The result of anti-mutagenicity suggested that the ethanol extract of R. glutinosa Preparata showed stronger activity than that of R. glutinosa ethanol extract. All of the ethanol extracts showed over 50% growth inhibition of several cancer cell lines. Especially, 61% of the cell growth of Hep3B was inhibited by adding 1g/ l of ethanol extract of R. glutinosa Preparata. In hypoglycemic activities and controlling blood pressure, 63.69% of ${\alpha}-glucosidase$ and 56.58% of ACE activities were inhibited by adding 1g/ l of ethanol extract of R. glutinosa Preparata. In general, the ethanol extract of R. glutinosa Preparata showed higher biological activities than those of R. glutinosa.

  • We studied the anti-diabetic effects of medicinal herb water extracts on expression of hepatic glucokinase (GCK), pyruvate dehydrogenase (PDH), and acetyl-CoA carboxylase (ACC) mRNA. The medicinal herbs used for experiments were Cornus officinalis (CO), Paeonia suffruticosa Andrews (PSA), Discorea japonica Thunb. (DJ), Rehmannia glutinosa (RG), Lycium chinense (LC), and Pyrus pyrifolia (PP). For GCK mRNA expression, CO, RG, and LC water extracts exhibited a more effective activity than other extracts. Cells treated with RG and LC water extracts showed an increase in expression of PDH mRNA to 191% and 124%, respectively, compared to control. Expression of ACC mRNA was significantly higher in LC water extract. These data indicate that CO, RG, and LC water extracts stimulates expression of hepatic GCK, PDH, and ACC mRNA.
