  • The peel of astringent persimmon (Diospyros kaki Thunb. cv. Cheongdo-Bansi) is a by-product of dried persimmon (gotgam). We investigated if deastringent peel extracts of persimmon cv. Cheongdo-Bansi had antioxidative and neuroprotective properties. Two different extracts were prepared: thermally and nonthermally treated persimmon peel extracts (TPE and NTPE, respectively). Both TPE and NTPE were fractionated sequentially in n-hexane, chloroform, ethyl acetate, n-butanol, and water. The TPE and NTPE ethyl acetate fractions had the highest total phenolic and flavonoid contents as well as antioxidant capacities among all the fractions. Pretreatment of neuronal PC-12 and SH-SY5Y cells with the TPE and NTPE ethyl acetate fractions increased cell viability after exposure to oxidative stress. The ethyl acetate fraction of TPE attenuated oxidative stress inside both PC-12 and SH-SY5Y cells more effectively than that of NTPE. Furthermore, the TPE and NTPE ethyl acetate fractions inhibited acetylcholinesterase and butyrylcholinesterase. Analysis of ultra-high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry results revealed gallic acid, kaempferol, kaempferol-3-O-galactoside, kaempferol-3-O-glucoside, quercetin, quercetin3-O-galactoside, quercetin-3-O-galactoside-2'-O-gallate, and quercetin-3-O-glucoside as the major phenolics of the TPE and NTPE ethyl acetate fractions. Taken together, these results suggest that the ethyl acetate fraction of deastringent persimmon peel is rich in antioxidants and has potential as a functional food to reduce oxidative stress.

  • To make a objective diagnosis of the syndrome of cold-limbs, We investigated the 20 patients with cold limbs and GI trouble and 20 normal people as a control group. And we compared the thermal difference between Chon-jung(CV17) and Chung-wan(CV12 中脘), Chon-jung(CV17) and Ki-hae(氣海 CV6) and we compared the thermal differences of No-gung(PE8 勞宮) and Yong-chon(湧泉 KI1), too. The results were as follows. 1. All 20 patients had GI trouble and cold limbs. They had the symptom-Indigestion(16 cases-80%) with heart burn, tympanites, abdominal distention, hiccup, belching. Beside that symptom they also had constipation(6 cases-30%), diarrhea(3 cases-15%), headache & dizziness(6 cases-30%). And some had the menstrual syndrome, chronic fatigue, palpitation, insomnia, edema, arthralgia. 2. The thermal difference of the palms between the patients group and the control group were $25.70^{\circ}C,\;25.82^{\circ}C$, but they were not significant. 3. The thermal difference of the soles between the patients group and the control group were $23.58^{\circ}C,\;24.42^{\circ}C$ and the significancy was P=0.020 so it was significant(P<0.05). 4. The thermal difference of the palms and Chon-jung(CV17) between the patients group and the control group were $1.08^{\circ}C,\;0.76^{\circ}C$, but they were not significant. 5. The thermal difference of the sales and Chon-jung(CV17) between the patients group and the control group were $3.01^{\circ}C,\;1.90^{\circ}C$ and the significancy was P=0.003 so it was significant(P<0.05). 6. The thermal difference of Chon-jung(CV17) and Chung-wan(CV12 中脘) between the patients group and the control group was $0.30^{\circ}C,\;0.62^{\circ}C$ and the significancy was P=0.793 so it was significant(P<0.05). 7. The thermal difference of Chon-jung(CV17) and Ki-hae(CV6 氣海) between the patients group and the control group was $0.53^{\circ}C,\;0.68^{\circ}C$, but they were not significant. From the above, I could find the significance of D.I.T.I to diagnose the cold-feet not the cold-hands and the thermal difference between the trunk and limbs was more significant on cold-feet than on cold-hand, either.

  • Objectives : This study was performed to evaluate the effects of moxibustion on cerebral blood flow, peripheral blood flow and blood pressure. Methods : We designed a randomized, cross-over study that included 20 healthy, male volunteers who were randomly assigned to one of two groups (the moxibustion group or the control group). The initial trial was followed by a washout period of one week before the groups were switched and the trial repeated. The cerebral blood flow and peripheral blood flow of the volunteers in both groups were measured by mean velocity (Vm), peak systolic velocity (Vs), pulsatility index (PI), perfusion units (PU) and mean blood pressure (BP) before the intervention (baseline), 30 minutes after the intervention, and again 60 minutes after the intervention. Results : 1. The Vm increased significantly in the moxibustion group. The Vs also constantly increased in moxibustion group, but there was no significant difference. 2. The PI decreased significantly in the control group at 0-30 minutes and in the moxibustion group at 30-60 minutes. 3. The PU constantly decreased in moxibustion group. In control group, the PU decreased at 30 minutes and increased slightly at 60 minutes. 4. The mean blood pressure did not show any significant difference between the two groups. Conclusions : This study shows that moxibustion at CV12 increased the cerebral blood flow. Based on this result, we can suggest that moxibustion at CV12 might be helpful in improving the functional recovery of stroke patients. However, further research needs to be conducted on a larger numbers of subjects in order to confirm these effects.

  • Background: Abdominal obesity as measured by waist-to-height ratio (WHtR) may have stronger and inverse associations with cardiovascular (CV) health than overall obesity as measured by body mass index (BMI). However, there was some challenges for controversies. We aimed to examine the associations of WHtR and BMI with CV health among Korean children using data of the 2010-2012 Korea National Health and Nutrition Examination Survey. Methods: A cross-sectional study was conducted with the sample of 2,363 children by analyzing by gender and two-age groups (10-12 and 13-18 years). Overall obesity was categorized into 3 groups by BMI percentile: non-overweight (<85), overweight (${\geq}85$), and obesity groups (${\geq}95$). Abdominal obesity was categorized into 2 groups by WHtR: normal (<0.5) and abdominal obesity groups (${\geq}0.5$). The CV health score was defined as a z-score by calculating the sum of 7 CV factors. Results: The overweight/obesity groups had significantly lower CV health scores than the normal group (P<0.05) in boys and girls aged either 10-12 years or 13-18 years after adjusting for covariates. The abdominal obesity group also showed significantly lower CV health scores than the normal group (P<0.05) in all the groups; this significant association remained significant in boys aged 13-18 years even after further adjusting for BMI category (P<0.01). Conclusions: Among boys aged 13-18 years, abdominal obesity as measured by WHtR was significantly and inversely associated with CV health, independent of BMI category. Therefore, it should be considered to assess the level of abdominal obesity as a measure of CV health in late adolescent boys.

  • Objectives: This study was designed to investigate the protective effects of Atractylodis Rhizoma pharmacopuncture (ARP) against acute gastric mucosal lesions induced by compound 48/80 in rats. Methods: The ARP was injected in Joksamni (ST36) and Jungwan (CV12) 1 hr before treatment with compound 48/80. The animals were sacrificed under anesthesia 3 hrs after treatment with compound 48/80. The stomachs were removed, and the amounts of gastric adherent mucus, gastric mucosal hexosamine, thiobarbituric acid reactive substances (TBARS), xanthine oxidase (XO), and superoxide dismutase (SOD) were measured. Also, histological examination were performed. Results: Gastric adherent mucus, gastric mucosal hexosamine and histological defects of gastric mucosa declined significantly after ARP treatment. Changes in gastric mucosal TBARS were also reduced by ARP treatment, but this result was not statistically significant. ARP treatment did not change the XO and the SOD activities. Conclusions: ARP showed protective effects for acute gastric mucosal lesions induced by compound 48/80 in rats. These results suggest that ARP may have protective effects for gastritis.

  • To determine anti-lodging effect of paclobutrazol and its influence on yield of rice, paclobutrazol was applied at 12 and 18g ai/10a to cv. Nakdongbyeo and cv. Seomjinbyeo 20, 15, and 10 days before heading under 12 and 20kg/10a nitrogen conditions. 1. Paclobutrazol reduced internode length of rice, especially internode N3. Higher suppression of stem of both cultivars and reduction of ear length in cv. Nakdongbyeo were observed when paclohutrazol was applied at 18g ai/10a 15 and 20 days before heading. 2. Paclobutrazol increased culm cross-section area, culm diameter, linear density and stem flexure resistance which affected anti-lodging efficacy. Although actual lodging was not occurred in field, less stem inclination was observed at paclobutrazol treated plots. 3. There were significant correlation between stem flexure resistance and culm cross-section area, culm diameter and linear density, and negative correlation between straw inclination angle and culm cross-section area and culm diameter. 4. Slight yield reduction was observed when paclobutrazol was applied at 18g ai/10a 20 days before heading. However, when paclobutrazol was applied at 12g ai/10a 10 and 15 days before heading, rice yield was not decreased compared to untreated control.

  • This study was conducted to investigate the Net photosynthesis and respiration rates among the varieties of Soybean(Eunha, Pangsa and Paldal that have high yields) at various leaf temperature and light intensity at the stage of $V_5$. The relations between the Net photosynthesis rate and SLW(specific leaf weight) and chlorophyll content were also investigated. 1. Net photosynthesis rates at $25^{\circ}C$ were $21.5mgdm^{-2}h^{-1}$ in cv. Eunha, $20.2mgdm^{-2}h^{-1}$ in cv. Pangsa and $18.5mgdm^{-2}h^{-1}$ in cv. Paldal. 2. Most cultivars of Soybean showed the maximum rates of Net photosynthesis at $25^{\circ}C$, especially in cv. Eunha. Also Net photosynthesis rates differed depending on the leaf shape. Long leaf shape(cv. Eunha) was better than round leaf shape(cv. Paldal) in Net photosynthesis rate. 3. Respiration rates of leaves in Eunha, Pangse and Paldal were $0.56mgdm^{-2}h^{-1}$ at $15^{\circ}C$, $0.79mgdm^{-2}h^{-1}$ at $20^{\circ}C$ $1.15mgdm^{-2}h^{-1}$ at $25^{\circ}C$ and $1.37mgdm^{-2}h^{-1}$ at $30^{\circ}C$. 4. Specific leaf weight were $3.1mg/cm^2$ in Pangsa, $3.5mg/cm^2$ in Eunha and Paldal. No signlficant difference were showed in net photosynthesis rates and specific lear weight. 5. Leaf chlorophyll content were $2.48{\mu}g/gF.W.$ in Eunha, $2.19{\mu}g/gF.W.$ in Pangsa and $1.67{\mu}/g F.W.$ in Paldal. Significant difference were showed in Net photosynthesis rates and Leaf chlorophyll content. 6. The estimated compensation points at which net photosynthesis approached zero were $10{\mu}Em^{-2}s^{-1}$ in Eunha, Pangsa, and Palda at 1$5^{\circ}C$. The compensation point in cv. Eunha at $20^{\circ}C$ was $12P{\mu}Em^{-2}s{-1}$ while $13{\mu}Em^{-2}s{-1}$ in Pangsa and Palda. The compensation point in cv. Paldal at $25^{\circ}C$ was $18{\mu}Em^{-2}s{-1}$ while $16{\mu}Em^{-2}s{-1}$ in Eunha and Pangsa. The compensation point in cv. Palda at $30^{\circ}C$ was $23{\mu}Em^{-2}s{-1}$ Palda while $13{\mu}Em^{-2}s{-1}$ in Eunha and Pangsa.
