吸引野生鸟类、蝶类的乡土食源植物虾子花(Woodfordia fruticosa)生态景观营造实践

在南方利用优良的鸟类、蝶类食源植物虾子花(Woodfordia fruticosa)可在3~5年内构建有效吸引野生鸟类如红耳鹎(Pycnonotus jocosus)、白头鹎(Pycnonotus sinensis)、叉尾太阳鸟(Aethopyga christinae)、暗绿绣眼鸟(Zosterops japonicus)、朱背啄花鸟(Dicaeum cruentatum)、红胸啄花鸟(Dicaeum ignipectus)、橙腹叶鹎(Chloropsis hardwickii)和北红尾鸲(Phoenicurus auroreus)等,蝶类如巴黎翠凤蝶(Papilio paris)、玉斑凤蝶(Papilio helenus)、玉带凤蝶(Papilio polytes)、青凤蝶(Graphium sarpedon)及报喜斑粉蝶(Delias pasithoe)等的生态景观。进一步对虾子花的栽培管护技术、整体景观构建等提出建议。

Hepatoprotective effect of Woodfordia fruticosa Kurz flowers on diclofenac sodium induced liver toxicity in rats

Objective:To evaluate the protective effect of Woodfordia fruticosa Kurz flowers against experimentally induced liver toxicity in rats.Methods:Two different doses of methanol extract of Woodfordia fruticosa(WFM) were evaluated for the hepatoprotective activity against diclofenac sodium induced hepatotoxicity in rats.Various biochemical parameters like alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase(ALP),total protein(TP),albumin(ALB),blood urea nitrogen(BUN) from serum;total protein(TP),glutathione (GSH) levels,catalase(CAT) and glutathione peroxidase(GPx) activities from liver were studied; histopathologic changes of liver were also evaluated.Results:WFM effectively reduced the elevated levels of serum ALT,AST,ALP and BUN,enhanced the reduced TP,ALB and hepatic GSH,CAT,GPx activity.The histopathological analysis suggested that WFM decreased the degree of liver fibrosis induced by diclofenac.Conclusions:This study demonstrates the hepatoprotective activity of WFM and thus scientifically support the use of this plant in traditional medicine for the treatment of liver disorders.
