Immunomodulatory Effects of a Bioactive Compound Isolated from Dryopteris crassirhizoma on the Grass Carp Ctenopharyngodon idella
In the present study, we investigated effects of compound kaempferol 3-a-L-(4-O-acetyl)rhamnopyranoside-7-a-L-rhamnopyranoside (SA) isolated from Dryopteris crassirhizoma during immune-related gene expression in Ctenopharyngodon idella head kidney macrophages (CIHKM). The expression of immune-related genes (IL-1β, TNF-α, MyD88, and Mx1) were investigated using real-time PCR at 2 h, 8 h, 12 h, a...
متن کاملAntioxidant activity of two phloroglucinol derivatives from Dryopteris crassirhizoma.
The rhizome of Dryopteris crassirhizoma NAKAI exhibited significant antioxidant activity, as assessed by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity in vitro. Two phloroglucinol derivatives, flavaspidic acids PB (1) and AB (2), were isolated from the rhizome of D. crassirhizoma by a bioassay-guided fractionation. 1H-, 13C-NMR, and UV analysis were used to determine the ...
متن کاملCytological Features of the Egg Cell Protoplasts Isolated from Gametophytes of Fern, Struthiopteris niponica (Kunze) Nakai
Egg cell protoplasts were isolated from the gametophyte of the fern, Struthiopteris niponica (Kunze) Nakai. Archegonia were excised from the prothallia and then digested in an enzyme solution that contained Cellulase "Onozuka" RS and Macerozyme R-10. After 3 hours of incubation, the egg cell protoplasts had separated completely from the somatic cells. The protoplasts had such cytological featur...
متن کاملAnti-Influenza Virus (H5N1) Activity Screening on the Phloroglucinols from Rhizomes of Dryopteris crassirhizoma.
For screening the active phloroglucinols on influenza virus (H5N1) from Dryopteris crassirhizoma NaKai, a database was established including twenty-three phloroglucinols that had been isolated from Dryopteris crassirhizoma. Their inhibitory effect on the neuraminidase (NA) of influenza virus H5N1 was screened by molecular docking. As a result, three candidates were selected. The rhizomes of D. ...
متن کاملEffect of bracken (Pteridium a quilinum) and dryopteris (Dryopteris juxtaposita) fern toxicity in laboratory rabbits.
Experimental studies with Bracken and Dryopteris ferns @ 25% concentrate ration mixture were conducted in rabbits. Fern fed rabbits showed progressive anaemia, leukopaenia, lymphopaenia and relative heterophilia. Significant elevations in serum enzymes like serum glutamate oxaloactate transminase (SGOT), serum glutamate pyruvate transminase (SGPT), alkaline phosphatase (ALP), urea and creatinin...
