Den er varm af natur og s\u00f8d i smagen og har den virkning, at den giver n\u00e6ring til lever og nyrer, styrker muskler og knogler og forebygger abort. Den bruges ved tilstande som lever- og nyremangel, smerter i talje og kn\u00e6, muskelsvaghed, svimmelhed, blodl\u00e6kage under graviditet og ustabilt foster. Eucommia ulmoides er hovedsageligt udbredt i provinser som Hunan, Hubei, Henan, Shanxi og Sichuan. Det er en national andenklasses beskyttet plante, og dens hovedkomponenter omfatter lignaner, iridoider, flavonoider, phenylpropanoider, terpener, polysaccharider osv. Moderne farmakologisk forskning har vist, at Eucommia ulmoides har farmakologiske virkninger som f.eks. s\u00e6nkning af blodtrykket, regulering af blodlipider, s\u00e6nkning af blodsukkeret, antitumor, antibakteriel, antiinflammatorisk, antioxidant, lever- og nyrebeskyttelse og antiosteoporose. Diabetes er en stofskiftesygdom med h\u00f8j forekomst og h\u00f8j d\u00f8delighed. Diabetesnefropati er en af de mest almindelige komplikationer hos diabetespatienter og er ogs\u00e5 den mest almindelige \u00e5rsag til nyresvigt i slutstadiet. At finde l\u00e6gemidler, der kan forbedre nyrefunktionen i et milj\u00f8 med h\u00f8jt glukoseindhold, har vigtig klinisk v\u00e6rdi. Forskning har vist, at Eucommia ulmoides lignaner kan reducere urinproteinniveauet hos rotter med nyreskade, h\u00e6mme angiotensin II-induceret proliferation af glomerul\u00e6re mesangiale celler, forbedre nyrefunktionen og have en beskyttende effekt mod hypertension-induceret nyreskade. Det kan ogs\u00e5 h\u00e6mme morfologiske \u00e6ndringer i renale r\u00f8rformede epitelceller for\u00e5rsaget af h\u00f8jt glukoseindhold og modvirke transdifferentiering af renale r\u00f8rformede epitelceller for\u00e5rsaget af h\u00f8jt glukoseindhold, men de specifikke aktive ingredienser er ikke blevet bestemt. For at berige den kemiske sammens\u00e6tning og de strukturelle typer af Eucommia ulmoides blev forbindelser med nyrebeskyttende aktivitet screenet fra Eucommia ulmoides lignaner. I dette eksperiment blev lignaner fra Eucommia ulmoides barkvandsekstrakt isoleret og identificeret, og forbindelser fra Eucommia ulmoides lignaner, der kunne h\u00e6mme mesangialcelleproliferation induceret af h\u00f8j glukose, blev forel\u00f8bigt screenet ved MTT-assay.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-7512\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/1-309.png\" alt=\"\" width=\"779\" height=\"369\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/1-309.png 779w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/1-309-768x364.png 768w\" sizes=\"(max-width: 779px) 100vw, 779px\" \/><\/p>\n<p>Denne unders\u00f8gelse isolerede og identificerede seks lignaner fra vandekstraktet af Eucommia ulmoides-bark, hvoraf forbindelse 1 blev isoleret fra Eucommia ulmoides for f\u00f8rste gang. Forskning har bekr\u00e6ftet, at Eucommia ulmoides-ekstrakt har en god beskyttende effekt p\u00e5 nyreskader. Samtidig har unders\u00f8gelser rapporteret, at Eucommia ulmoides lignaner kan h\u00e6mme angiotensin II-induceret mesangialcelleproliferation hos rotter og fremme celleapoptose ved at fremme opreguleringen af P21-, P27- og Bax-ekspression og derved ud\u00f8ve nyrebeskyttelse. De specifikke aktive ingredienser, der ud\u00f8ver beskyttende virkninger, er dog endnu ikke blevet bestemt. P\u00e5 baggrund af forskning i kemisk sammens\u00e6tning fandt denne artikel gennem MTT-assay, at Eucommia ulmoides lignanforbindelser 2, 3 og 4 kan h\u00e6mme h\u00f8jglukoseinduceret spredning af humane glomerul\u00e6re mesangiale celler ved visse koncentrationer, og forbindelse 5 kan effektivt h\u00e6mme h\u00f8jglukoseinduceret spredning af glomerul\u00e6re mesangiale celler p\u00e5 en dosisafh\u00e6ngig m\u00e5de, hvilket indikerer, at forbindelse 5 har en god nyrecellebeskyttende effekt. Denne unders\u00f8gelse beriger forbindelsesbiblioteket af Eucommia ulmoides medicinske materialer og giver et materielt grundlag for screening af blyforbindelser med nyrebeskyttende aktivitet.<\/p>","protected":false},"excerpt":{"rendered":"<p>Study on the lignans in Eucommia ulmoides bark and their protective effects on high glucose induced glomerular mesangial cells Eucommia ulmoides is the dried bark of Eucommia ulmoides Oliv., a plant in the Eucommia family.
