The bark of the root and stem of Ulmus davidiana var. japonica has been used as a traditional Korean medicine to treat inflammatory disorders. This plant reportedly shows antioxidant, anticancer, and anti-inflammatory effects. In this study, we investigated the protective effects of Ulmus davidiana var. japonica ethanolic extract (UDE) on UVB irradiation-induced wrinkle in hairless mice. We evaluated for their free radical-scavenging activities against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and the anti-elastase activities, and for their anti-matrix metalloproteinase-1 (MMP-1) activity in human skin fibroblast cells. In the wrinkle measurement and image analysis of skin replicas, the results showed that UDE significantly inhibited wrinkle formation caused by chronic UVB irradiation. These results suggest that UDE has anti-wrinkle activity.

Ulmus parvifolia has been used as a traditional folk medicine to treat the carbuncle in deep skin. In this study, the effect of water extract of root bark of Ulmus parvifolia (WUP) on the carbuncle, pain, inflammation and hypersensitivity was evaluated in animal models. The administration of WUP significantly decreased the size of Staphylococcus aureus ($10^8$ cells/mouse)-induced carbuncle, and also exhibited analgesic activity in the HAc-induced writhing syndrome at doses of 50-500 mg/kg. It also showed significant anti-inflammatory activity in the carageenin- and complete Freund's adjuvant-induced inflammation. In the histamine-induced anaphylaxis, it decreased the percent of mortality by protecting mice treated with Bordetella pertussis. In the immune responses in the mice sensitized and challenged with sheep red blood cells, the Arthus reaction determined by swelling of foot pad at 4 h after challenge, HA titer, HY titer and PFC which can be used to evaluate the humoral immune response were significantly suppressed by oral administration of WUP at doses of 100 and 200mg/kg. The cellular immune responses in the same mice such as delayed type hypersensitivity determined by swelling of foot pad at 24 h after challenge and RFC were also significantly suppressed in the same manner.

This study was conducted to investigate the effects of Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts on blood hemoglobin, $HbA_{1c}$, levels and biomarkers in the streptozotocin (STZ)-induced diabetic rats. Male Wistar rats divided into normal and diabetic groups. The diabetic groups subdivided into the control group (DM) and Araliaceae water extracts supplemented groups: Aralia elata (AE), Acanthopanacis cortex (AC) and Ulmus davidiana (UD). The extracts were supplemented in diet base on 11.42 g of raw Araliaceae/kg diet for 7 weeks. The diabetes was induced by injecting 572 (55 mg/kg B.W., i.p.) once 2 weeks before sacrifying. Relative weights of liver were significantly lowered in the DM group compared to the normal group, whereas those of kidney and heart were significantly increased in the DM group. Supplementation of the Araliaceae water extracts improved reduced liver weights in STZ-induced diabetic rats. Blood glucose level was significantly higher in the DM group than in the normal group, whereas insulin contents were significantly lowered in the DM groups. However, these parameters were normalized in the An, AC and UD supplemented groups, respectively. Blood hemoglobin and $HbA_{1c}$ levels were significantly higher in the DM group than in the normal group. When all of Araliaceae water extracts were supplemented to the diabetic rats lowered hemoglobin and $HbA_{1c}$ levels. Red blood cell, white blood cell and Lymphocyte were significantly higher in the DM group than in the normal group. The supplementation of Araliaceae family water extracts significantly lowered these parameters compared to the DM group. MCV, MCH contents were declined in the DM group, while the supplementation of Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts elevated of these contents in STZ-induced diabetic rats. Accordingly, these results indicate that Aralia elata, Aeanthopanacis corex and Ulmus davidiana water extracts would seem to improve the blood biomarkers in STZ-induced diabetic rats.

고부가가치를 가진 천연식물 발효음료를 개발하기 위하여 감과 보리, 백야초와 느릅나무 등을 이용하여 3종류의 발효액과 1종류의 침출주를 제조한 후 이들의 생리기능성을 조사하였다. 노화관련 생리기능성으로 항산화활성은 느릅나무 침출주에서 99%로 제일 높았고 감으로 제조한 감식초에서도 68.3%를 보였다. 또한 SOD 유사활성은 느릅나무 침출주에서 80.6%로 제일 높았으나 여타의 발효액에서는 25% 미만의 낮은 활성을 보였다. 심혈관질환관련 생리기능성으로 항고혈압성 안지오텐신 전환효소(ACE) 저해활성과 혈전용해활성은 모두 11% 이하의 낮은 활성을 나타내었고 항치매성 아세틸콜린 에스터레이즈(AChE) 저해활성은 느릅나무 침출주에서 54.7% 높았으나 여타의 시료에서는 10% 미만의 낮은 활성을 보였다. 이상의 결과들을 종합하여 볼 때 대체로 느릅나무 침출주가 강력한 항산화활성을 갖고 있고 SOD 유사활성과 AChE 저해활성도 우수하였으므로 고부가가치의 건강 주류로 산업화가 가능한 것으로 사료된다.

Objective: The root bark of Ulmus davidiana var. Japonica (Ulmi Radicis cortex, URC) is a medicinal herb used for promoting diuresis and treating dampness. In Korea, URC has long been used as an efficacious therapy for inflammation, burns, frostbite and skin diseases such as eczema and psoriasis. Methods: In the present study, we used 1-fluoro-2,4-dinitrofluorobenzene (DNFB)-induced contact dermatitis (CD) mouse model to investigate the anti-allergic and the anti-inflammatory effects of URC on skin lesion, histopathological changes and specific antibody production. Results: URC treatment, 10 mg/mL, effectively inhibited skin lesions induced by repeated paintings with DNFB. In the histopathological observation, topical application of URC inhibited spongiosis. In addition, URC lowered the production levels of total immunoglobulin and IgG2a in serum. Conclusion: These data indicate that URC has an anti-inflammatory effect that produces an improvement of skin lesions in CD mice.

This study aimed to assess the antioxidative potential of adding ethanolic extracts from Ulmus davidiana to Yackwa (Korean fried cookie). The reducing power and antioxidant activity of U. davidiana-treated Yackwa were assessed against DPPH, nitric oxide, superoxide anions, superoxide dismutase, and ABTS radicals. Increasing the amount of U. davidiana extract in Yackwa dough resulted in improved antioxidant properties. U. davidiana extracts were effective antioxidants with a radical scavenging potency similar to the potency of butylated hydroxytoluene (BHT) and L-ascorbic acid. The DPPH and nitric oxide radical scavenging activity of Yackwa containing 0.2% U. davidiana resulted in increased oxidative stability relative to control dough. Although the antioxidant effects of Yackwa containing U. davidiana extract were lower than those of Yackwa containing BHT and L-ascorbic acid, these results suggest that U. davidiana extracts have potent antioxidant activity. Accordingly, U. davidiana extract is a potential additive for deep-fried foods, such as Yackwa, to improve their oxidative stability.

From a review of the literature it was found that 96 species of fungi have been reported as occurring on the wood of Ulmus americana L., the Amercan elm. In an intensive study of the fungi growing on one American elm log, 60 species were found. Only one had been reported previously on American elm. A second fungus proved to be a hyperparasite of a slime mold. Three members of the Fungi Imperfecti could not be identified and is believed that they may constitute new taxa. In the past, Nasidiomycetes constituted the main group of fungi on American elm wood according to the literature. The Fungi Imperfecti were the largest group in this study in that over half of the species found are imperfect fungi. All of the species encountered in the study were illustrated.
