  • Objectives : In order to distinguish morphological characteristics of trunk bark and root bark of Ulmus davidiana var. japonica (Rehder) Nakai and the trunk bark and root bark of Hemiptelea davidii Planchon were sampled and compared in terms of their external and internal features with flour states according to their medical use, through microscopic examination. Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and the flour of it was mounted by the liquid made by the same ratio of each of glycerin, acetic acid, and water, and then observed and photographed by olymphus-BHT. Results : 1. Internal Features 1) A large parenchymatous cell was observed in the phloem of the slice of both trunk bark and root bark of Ulmi Cortex, However, both of the trunk bark and root bark of Hemipteleae Cortex did not have parenchymatous cell in the phloem; instead, stone cells including much square crystal of calcium oxalate were distributed around fiber bundle, and the parenchymatous cell included much druse crystal of calcium oxalate. 2) In both the Ulmi Cortex and Hemipteleae Cortex, rhytidome was observed in trunk bark, but not in root bark, but in the parenchymatous cell of the root bark of the Ulmi Cortex contained starch grain. 2. Flour States 1) In the flour of root bark of the Ulmi Cortex, a large parenchymatous cell was observed. However, in the flour of trunk bark and root bark of Hemipteleae Cortex, no parenchymatous eel was found; instead, stone cell including square crystal of calcium oxalate and druse crystal of calcium oxalate were observed. 2) There was no remarkable difference between the trunk bark and root bark of Hemipteleae Cortex. However, starch grain was contained in the parenchymatous cell of the root bark of Ulmi Cortex but not in the trunk bark of it. Conclusions : There were some morphological differences in external, internal, and flour parts of Ulmi Cortex and Hemipteleae Cortex. In particular, there was a morphological difference in flour states between the trunk bark and root bark of Ulmi Cortex, it is possible to use microscope to distinguish their flour states.

  • From mulberry root bark of 13 various varieties, ${\gamma}$-Aminnobutyric acid(GABA) contents were examined on HPLC analyzer. GABA contents in mulberry root bark were affected by genotypes. Average GABA content of the 13 mulberry varieties was 2.19 mg/gDW. GABA content of the varieties ranged from 1.70 to 2.62 mg/gDW. Among the three genotypes, GABA content of the Morus Lhou was higher than the other genotype. In GABA content Hongolppong was the highest with 2.62 mg/gDW on the 13 varieties of mulberry root bark.

  • Objectives : The root bark of Dictamnus dasycarpus has been frequently used to treat patients with skin diseases in Korea. Recently, wild root of D. dasycarpus are reported to induce liver injury. Methods : Traditional uses of D. dasycarpus for skin diseases were analysed bibliographically. In addition, reported cases were collected and analysed using pubmed and national digital library. Results : In taiwan, D. dasycarpus revealed to be one of major herbs for skin diseases and many researchers in worldwide had reported its dermatological efficacies. Reported cases related in liver injury described that hepatocellular or cholestatic liver injury were seen in patients eating wild root of D. dasycarpus. In addition, 6 cases in worldwide and 1 case in Korea showed that patients with drug induced liver injury (DILI) ingested not root bark of D. dasycarpus but prescriptions containing root bark of D. dasycarpus. These mean that wild root of D. dasycarpus (Bongsam or Bongwhangsam) was estimated to be closely related in DILI. Whereas, it was difficult to confirm direct correlation between root bark of D. dasycarpus used as herbal medicine by doctor of Korean medicine and DILI. Conclusions : these results imply that wild root of D. dasycarpus is closely related in DILI and strong recommendation not to take it without consultation by experts is needed. In addition, although there are no evidences of direct correlation between root bark of D. dasycarpus and DILI, doctor of Korean medicines should pay attention to use root bark of D. dasycarpus in their clinics.

  • Objectives : The trunk-bark and the root of A. elata were compared with each other in terms of their anti-oxidative activities. Methods : Using the trunk-bark and the root of A. elata, their anti-oxidative activities were examined through the in vitro and in vivo experiments. Results : The trunk-bark of A. elata in vitro had weaker anti-oxidative activities than its root. However, the trunk-bark of A. elata in vivo had stronger anti-oxidative activities than the root in the rats which was oxidatively stressed by alcohol. Conclusion : These results suggested that the trunk-bark of A. elata was also useful as a medicine.

  • Soil amendments with oriental herbal medicines such as fruit of Anethum graveolens, flower buds of Syzygium aromaticum, rhizome of Cnidium officinale, rhizome of Coptis chinensis, root bark of Paeonia suffructicosa, stem bark of phellodendron amurense, and stem bark of Cinnamomum cassia at the rate of 0.2% (weight by volume of soil) significantly reduced Meloidogyne incognita infection (root gall formation) of tomato seedlings compared with the control. The most effective treatments were root bark of p. suffructicosa and stem bark of C. cassia as they gave minimum numbers of galls on tomato roots (4.7% and 8.9%, respectively, relative to control) as compared to other treatments. Another study with root bark of p. suffructicosa and C. cassia at different application doses also showed consistent results in reducing gall number. The control efficacy decreased as the application doses were lower-ed, indicating their dose-dependent control activities. These treatments significantly enhanced aboveground plant growths (total masses).

  • Yam (Dioscorea batatas) is widely consumed as functional food for health promotion mainly in East Asia countries. We assessed whether yam root (tuber) or bark (peel) extracts stimulated the activity of osteoblasts for osteogenesis. MC3T3-E1 cells (mouse osteoblasts) were treated with yam root extracts (water or methanol) (study I) or bark extracts (water or hexane) (study II) within $0{\sim}10{\mu}g/mL$ during the periods of osteoblast proliferation (5~10 day), matrix maturation (11~15 day) and mineralization (16~20 day) as appropriate. In study I, both yam root water and methanol extracts increased cell proliferation as concentration-dependent manner. Cellular collagen synthesis and alkaline phosphatase (ALP) activity, both the indicators of bone matrix protein and inorganic phosphate production for calcification respectively, were also increased by yam root water and methanol extract. Osteoblast calcification as cell matrix Ca and P accumulation was also increased by the addition of yam root extracts. In study II, yam bark extracts (water and hexane) increased osteoblast proliferation and differentiation, as collagen synthesis and ALP activity and osteoblast matrix Ca and P deposition. The study results suggested that both yam root and bark extracts stimulate osteogenic function in osteoblasts by stimulating bone matrix maturation by increasing collagen synthesis, ALP activity, and matrix mineralization.

  • The methanol extract of Aralia elata root bark was found to decrease the blood glucose level in normal and alloxan-treated rats. The fractionation process confirmed positive activity in ethylacetate fraction. It is suggested that this fraction may show potent antihyperglyceimic activity through stimulation of insulin secretion.

  • The root-bark of the mulberry tree has been used as a medicine with antitussive, antiphlogistic, diuretic etc. in Korea. Among many kinds of mulberry trees, Morus Lhou has been widely cultivated in our country. In this experiment, three substances were obtained from the root-bark of Morus Lhou removed its cork layer by column chromatography of methanol extract. One of the substances was supposed as ${\alpha}$-amyrin acetate, another was alyceride, the other was confirmed as ${\beta}$-sistosterol by chemical and physical methods.
