Danggui Buxue Tang (DBT), a herbal decoction composed of Radix Astragali (RA) and Radix Angelica sinensis (RAS), has been used for treating menopausal irregularity in women for more than 800 years in China. According to the old tradition, RAS had to be processed with yellow wine before DBT preparation, which markedly reduced the amount of ligustilide in RAS and DBT, as well as enhanced the bioactivities of DBT. Here, we hypothesized that ligustilide would be an ingredient that possessed suppressive effects on DBTs functions. In the presence of ligustilide, the amount of astragaloside IV, calycosin, formononetin, and total polysaccharides extracted from RA were decreased. An increase of ligustilide caused a decrease of DBTs osteogenic activity in stimulating proliferation and differentiation of cultured bone cells. In addition, in the presence of a high level of ligustilide, DBT caused a side effect inducing the proliferation of breast MCF-7 cells. The current results strongly suggest that ligustilide is a negative regulator that hinders DBT to achieve its biological efficacy, which supports the traditional practice of preparing DBT using the ethanol-treated RAS.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
