Byungdug Jun,Kenshi Torao,Jieqi Fu,Yoshihiko Horiuchi,Jong-Hwan Kim,Eung-Nam Kim 대한공간정보학회 2016 Spatial Information Research Vol.24 No.3
In this study, the on-site remote sensing tech- nology was applied to the green tea field. This research is about the development of the management system named ‘‘N-system’’ as an experimental system and ‘‘T-system named Tsumigorou’’ as a real operation system to check the growth rate or environment state of the green tea. The purpose of this study is to apply to the production site with the green tea and make the management system named ‘‘T- system’’ by the name of ‘‘Tsumigorou’’. N-system was used to make a detailed field survey in many green tea fields in Japan. And then, This ‘‘N-system’’ has evolved network system into named ‘‘T-system’’ which consists of hardware and software. NDVI value was simulated as a result of ‘‘N-system’’ and ‘‘T-system’’. Through field sur- vey, the correlation coefficient of a component of green tea such as weight, total nitrogen, amino acids, and fiber and NDVI was calculated. In the results, NDVI G have a strong correlation coefficient with fibers. Its correlation coefficient between NDVI G and the fibers of third picked tea in 2011 was R2 = 0.90 at MIYAKONOJO green tea field. ‘‘T- system’’ has a good relationship (Total R2 = 0.76) between vegetable fiber and NDVI IR .
Effects of Manual Acupuncture at GB34 on Carbon tetrachloride-induced Acute Liver Injury in Rats

Manual acupuncture at Yanglingquan (GB34) is reported to have a beneficial effect on chronic liver damage. We, therefore, studied the effect of manual acupuncture at GB34 on acute liver damage. Rats were administered carbon tetrachloride (CCl₄) or olive oil, and direct manual acupuncture was subsequently performed at GB34 or at a sham point (a nonacupoint). In rats administered with CCl₄, the serum levels of aspartate aminotransferase and alanine aminotransferase, the total cholesterol concentration, and the levels of hepatic thiobarbituric-acid-reactive substances were suppressed by acupuncture at GB34 when compared with acupuncture at the sham point. By contrast, there was little histological difference in the liver between acupuncture at GB34 and that at the sham point in rats administered with CCl₄. These results suggest that manual acupuncture at GB34 tends to improve acute liver damage but is not sufficient by itself to completely resolve the hepatic injury.
The Effect of the Major Components of Fructus Cnidii on Osteoblasts In Vitro

In traditional Chinese medicine, the cause of weak bones or bone loss is generally regarded as a result of kidney deficiency. Fructus Cnidii (FC), which is also known as She-Chuang-Zi, is a traditional herb that has been claimed to have kidney warming effects that invigorate Yang. In this study, we tried to determine the bone production-inducing effect of FC on osteoblastic cells in vitro using osthole, the main component of FC. Osteoblasts were isolated from neonatal Sprague-Dawley rat calvaria using the tissue piece culture method and treated with various concentrations of osthole ranging from 2.5 to 640 μg/mL, together with a blank control. Cell proliferation,alkaline phosphatase (ALP) activity, and bone nodules were measured. The cells were examined by hematoxylin-eosin staining, the Gomori Calcium-Cobalt method and immunofluorescent staining. The 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyl tetrazolium bromide (or MTT) assay, ALP assay, and bone nodule results indicated significantly enhanced osteoblastic proliferation and differentiation at concentrations of osthole ranging from 40 to 320 μg/mL. Concentrations lower than 40 μg/mL seemed less effective, and cytotoxicity to osteoblasts was observed at concentrations higher than 320 μg/mL. These results indicate that osthole is effective at inducing osteoblastic bone formation through the up-regulation of ALP activity. FC is a Chinese herb used to treat lumbar pain in clinical practice. Further studies concerning the effects and mechanism of osthole on osteoporotic patients and animals should be performed, as these studies may lead to the development of a drug treatment for osteoporosis in the future.
A Pilot Study Exploring the Effects of Reflexology on Cold Intolerance
Wenping Zhang,Shougo Takahashi,Takashi Miki,Hisayo Fujieda,Torao Ishida 사단법인약침학회 2010 Journal of Acupuncture & Meridian Studies Vol.3 No.1
Cold intolerance is an inability to tolerate cold temperatures and is accompanied by symptoms including headache, shoulder discomfort, dizziness and palpitations. The current study was performed to examine whether reflexology therapy affected cold intolerance in human subjects and whether the treatment was systemically effective. Ten female volunteer examinees with subjective feelings of cold were examined. After a 5-minute foot bath, 10 minutes of reflexology therapy was performed on their left foot. Skin temperature and blood flow were estimated before and after treatment, together with an interview concerning their feelings of cold and daily habits. In addition, how the recovery rate was affected by the application of a chilled-water load was also estimated. Along with significant increases in skin temperature and blood flow compared with pre-treatment at the bilateral points of KI-1, LR-3, and BL-60, a faster recovery after the application of the chilled-water load was also seen in the lower limbs on both sides. From these results, we conclude that reflexology has systemic effects and is an alternative method for treating cold intolerance.

A previous study on rats showed that simultaneous acupuncture stimulation at the “Bai-Hui” (GV 20) and the “Yintáng” (Ex-HN3) acupoints alleviated the state of depression to an extent similar to that achieved by pharmacotherapy. This study investigated whether the alleviation of the depressed state required simultaneous acupuncture at these two acupuncture points. For the purposes of testing the effect of acupuncture on depressive symptoms, we treated a depression model rat, where depression had been induced by using a mild water-immersion stress technique, with either acupuncture stimulation at only one acupuncture point (GV 20 or Ex-HN3) or an antidepressant, and we measured the immobile time for evaluating the state of depression. Anxiety, as a symptom commonly associated with depression, was also evaluated by measuring the number of head dips. Neither the immobile time nor the number of head dips decreased upon acupuncture stimulation. From this study, single acupuncture stimulation at either “GV 20” or “Ex-HN3” alleviated neither the state of depression nor the anxiety. The water-immersion stress used to make the depression model rats was shown not to induce anxiety; however, the stress induced by immobilizing the rats for acupuncture stimulation did lead to anxiety.
