With the increase of cancer disease and the side-effects of the current treatments, researchers are attempting to find methods with less side-effect. The fern Adiantum capillus-veneris L. has triterpenoid compounds which have anti-tumor characteristics. This study aims to investigate the fatal effect of the extract of this plant on breast cancer (MCF-7) and normal (MRC-5) cell lines using MTT m...
زمینه و هدف: گیاه پرسیاوشان((Adiantum capillus-verenis از خانواده ی سرخس و دارای ترکیبات تری ترپنوئید است. از آنجائیکه تری ترپنوئید ها اثرات ضد تومور دارند و برروی DNA اثر می گذارند، در این تحقیق سعی شد که اثرات جهش زایی احتمالی عصاره متانولی این گیاه بااستفاده از تست ایمز بررسی شود. روش بررسی: عصاره گیری با روش خیساندن با متانول در مدت 48 سا...
Adiantum meishanianum is an endemic species distributed only in Meishan village, Kaohsiung, Taiwan. Because its sporangia contain only abortive spores, A. meishanianum has been regarded as having a hybrid origin, presumably with A. caudatum, A. malesianum, and A. philippense as the putative parents. The aim of this study is to confirm the hybrid origin and determine the parental lineages of A. ...
The effect of a hydrophilic extract of the fern Polypodium leucotomos (PLE) has been investigated in terms of photoprotection against UV-induced cell damage. PLE efficiently preserved human fibroblast survival and restored their proliferative capability when the cells were exposed to UVA light. This effect was specific and dose-dependent. Photoprotection was not restricted to fibroblasts, as de...
The maintenance of genetic diversity and stochastic losses of diversity during periods of small population size have become major points of concern in conservation biology. However, empirical research on random evolutionary processes in natural plant populations is still scarce and is reviewed here in comparison to our case study on Dryopteris cristata. Detailed recent population histories of t...
