Objective : The aim of this study was to evaluate the effects of Aconiti ciliare tuber on the descending pain and the recovery of locomotor function that results from sciatic crushed nerve injury in rats. Method : In order to assess the effects of the aqueous extract of Aconiti ciliare tuber on the recovery rate of locomotor function, we investigated the walking track analysis, and for the effects on the pain control we investigated brain-derived neurotrophic factor (BDNF) and inducible nitric oxide synthase (iNOS) expression in the sciatic nerve and on the expressions of c-Fos in the ventrolateral periaqueductal gray (vlPAG) region resulting from the sciatic crushed nerve injury in rats. Result : Treatment with Aconiti ciliare tuber significantly enhanced the SFIvalue, enhanced BDNF expression, decreased iNOS expression, and suppressed c-Fos expression. The present results showed that Aconiti ciliare tuber facilitated functional recovery following sciatic crushed nerve injury in rats. The recovery mechanisms of SFI by Aconiti ciliare tuber might be ascribed to the increase of BDNF expression for nerve regeneration and reinnervation and to the suppression of iNOS expression for inhibiting nerve inflammation. Conclusion : In this process it has been shown that Aconiti ciliare tuber can be used for pain control and functional recovery from peripheral nerve injury.

Background and Objective: The importance of the presence of eosinophils in the airways of patients with fetal asthma has long been recognized, but the mechanism by which these cells are recruited and retained in the lung are only now being elucidated. Eotaxin is a potent and specific eosinophil chemoattractant that is mobilized in the respiratory epithelium after allergic stimulation. Material and Methods: We used water extracts of Liripois Tuber and pulmonary epithelial cell lines A549(human typeII-like epithelial cells) and human eosinophils. We estimated cytotoxic effects of Liripois Tuber via MTS assay, and estimated the effects of Liripois Tuber on chemokines from prestimulated A549 cells by sandwich ELISA and RT-PCR. We conducted chemotaxis assay on prestimulated eosinophils treated with Liripois Tuber. Result: In this study we demonstrated that $TNF-{\alpha}$, IL-4 and $IL-1{\beta}$ induced the accumulation of chemokines mRNA in the pulmonary epithelial cell lines A549 in dose-dependent manner. Chemokines were inhibited by Liripois Tuber in dose-dependent manner. The eosinophil migration was inhibited at high concentration of Liripois Tuber. Conculusion: These findings indicate that the supression of the expression of chemokines can be accomplished by Liripois Tuber treatment, raising the possibility that Liripois Tuber might be of therapeutic value in diseases such as asthma.

Objectives : A morphological classification among Pinelliae Tuber, Typhonii Flagelliformis Rhizoma and Arisaematis Rhizoma was made through microscopic observation. Method : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Result : 1. Pinelliae Tuber is like a ball with a $1{\sim}1.5cm$ diameter, with a concave apex and pockmarked root trace around. 2. Typhonii Flagelliformis Rhizoma is somewhat oval or like a cone, with a $4{\sim}8mm$ diameter, a $7{\sim}15mm$ height, a projected round apex, and a pin-pointed back. 3. Arisaematis Rhizoma is somewhat flat round with a $2{\sim}2.5cm$ diameter, a little than Pinelliae Tuber, and its apex has incomplete lobopodium and root trace. 4. Fundamental tissues of Pinelliae Tuber, Typhonii Flagelliformis Rhizoma, and Arisaematis Rhizoma have starch grains and mucilage cells, and their mucilage cells include the raphides of calcium oxalate. Conclusion : Internal forms of Pinelliae Tuber, Typhonii Flagelliformis Rhizoma, and Arisaematis Rhizoma are difficult to distinguish from one another, but Pinelliae Tuber and Arisaematis Rhizoma can be distinguished by their external forms and sizes, and Pinelliae Tuber and Typhonii Flagelliformis Rhizoma were distinguished by the forms of apex.

For the mass production of plug seedlings in cultivar ‘Dejima’ potato (Solanum tuberosum L.) the optimal apical cutting diameter for rooting and rapid multiplication of stem cuttings in hydroponics were determined. In addition, the best planting date was predicted to increase tuber yield of plug seedlings at fall cropping in Cheju-Do, Korea. Days to initial rooting decreased as the cutting diameter was reduced. Plant height, leaf number, root length and root weight per plant were favorable as the cutting diameter was small. The ideal cutting diameter was 1-2 mm in this experiment. In the hydroponic cultures, the Japanese standard (JS) nutrient solution was the most effective for multiplication of stem cuttings. It was able to propagate more than 20 times a month from a single mother plant. Viability of plants, which were derived from plug seedlings using stem cuttings, was excellent when transplanted to the field. The number of tubers and tuber yield in both of the plug seedlings and seed potato planting plots were high when planted on 25 August. The number and yield were reduced when planted on 15 August, 5 September and 15 September. The degree of decrease of tuber yield in the plug seedling planting plot however, was lower than that of seed potatoes when the planting date was late. In the case of small tubers (under 30 g), the number of tubers and tuber yield were evidently increased in the seed potato tuber planting plot; the yield of large tuber (over 80g) in the plug seedling planting plot was higher than that of the seed potato. The total tuber yield per plant in the plug seedling planting plot was less than that of the seed potato; therefore, in order to increase tuber yield it was necessary to increase field plant density.

Purpose: Endometriosis has been thought to be related with blood stasis in uterus. Pinelliae Tuber is a herb which has effectiveness of dispelling phlegm which can be transformed into blood stasis, so is used in gynecology blood stasis-desease. Therefore in the present study, the effects of Pinelliae Tuber on endometriosis were investigated. Also retention enema therapy acts on the limited part directly, so is used frequently in gynecology clinic. This study was to examine the comparative effects on the surgical induction of endometriosis in the rat between orally and rectally administered with Pinelliae Tuber extract. Methods: The endometrial tissue was autografted to Rat's small intestine. Rats with surgically induced endometriosis were orally and rectally administerd with Pinelliae Tuber extract for 40 days. Size of ectopic uterine implants at the serosal wall and concentration of progesterone, estradiol, $TNF-{\alpha}$ and IL-2, IL-4, IL-6, IL-I0 in serum were examined and compared with the control group. Results: There was no difference in the size of ectopic uterine implants of experimental group compared with control group. The concentration of IL-10 level was significantly decreased in orally administered experimental group and the concentration of progesterone, IL-6 level was significantly decreased in rectally administered experimental group. There was no significant difference between orally and rectally administerd with Pinelliae Tuber. Conclusion: Judging from the above results, it can be suggested that Pinelliae Tuber should be not a useful agent for inhibiting the proliferation of uterine endometrial tissue. There is no difference between orally and rectally administerd with Pinelliae Tuber extract.

Corydalis Tuber has traditionally been used for the treatment of water retention in the body. Administration of the aqueous extract of Corydalis Tuber has been known to be effective for the control of pain and treatment of arthritis. It was reported that Corydalis Tuber possesses anti-inflammatory activity and modulates the intestinal immune system. The effect of Corydalis Tuber against LPS-stimulated expressions of COX-2, iNOS, and $IL-1{\beta}$ in cells of the murine RAW 264.7 macrophages was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, reverse transcription-polymerase chain reaction (RT-PCR), $PGE_2$ immunoassay, and NO detection. The aqueous extract of Corydalis Tuber was shown to suppress $PGE_2$ production by inhibition on the LPS-stimulated enhancement of COX-2 enzyme activity, $IL-1{\beta}$, and iNOS expression in the RAW 264.7 macrophages. Present results suggest that Corydalis Tuber exerts anti-inflammatory and analgesic effects probably by suppressing of COX-2, iNOS, and $IL-1{\beta}$ expressions, resulting in inhibition of $PGE_2$ synthesis. Corydalis Tuber has anti-inflammatory and analgesic effects probably by suppressing of COX-2, iNOS, and $IL-1{\beta}$ mRNA expressions, resulting in inhibition of $PGE_2$ and NO synthesis.

To give some information on the harvest and storage of Chinese yam (Dioscorea opposita), the experiment was done to examine the effect of its harvesting date and storage method on tuber weight, tuberrelated characters during the storageor at the end of storage. The yam tubers harvested 4 times at 20 days interval from Oct. 15 were stored with different storage methods(pit, room and cold temperature) and on Mar.15. all the characters were measured. Fresh weight of the tuber harvestedafter Nov. 5 and stored were greater than that done on Oct. 15 while dry tuber weight did not have any difference between the harvesting dates. The fresh weigth done directly from the field on Mar. 15 was higher compared to the other harvesting dates owing to its higher moisture content. The rate of sound tuber stored at room or cold temperature condition was higher than that at the field at which the rate was greater at the harvest after late nov. compared to the earlier harvests. Although the two storages were similar at sound tuber rates and marketable yield, the tuber weight was more reduced when stored at room temperature than when done at cold temperature . Brightness and value 'b' of chromaticaity realted to the tuber coloring and sugar content were higher but moisture content was lowerwhen harvested on Oct. 15 than the other havesting dates. All the characteristics realted to the marketability after storage were nearly same when stored at room and cold temperature. Value 'a' of chromaticity and sugar content were higher when harvest on Mar. 15 than when harvested before Dec. 15 but the 'b' value and mositure content were reverse results.
