Antiproliferative activity of Korean wild vegetables on different human tumor cell lines.

This study was conducted to determine the antiproliferative activity of 24 Korean wild vegetables. The methanol extracts of these wild vegetables were used against lung, breast, colon and gastric cancer cells, and the results were assessed by MTT assay. It was found that at the extract concentration of 400 mgL(-1) 14 plants exercised antiproliferative activity over 80% against the lung cancer cells, one plant among six--against breast cancer cells, and two plants among six--against colon cancer cells, respectively.

The influence of raw and processed garlic and onions on plasma classical and non-classical atherosclerosis indices: investigations in vitro and in vivo.

Garlic and white and red varieties of onion were subjected to processing by a variety of culinary methods, and bioactive compounds then determined. For in vivo studies, 84 male Wistar rats were randomly divided into 14 diet groups, each of six rats, including two control groups (one with no supplementation and one with cholesterol supplementation only). During the 30-day trial, the basal diets of the other 12 groups were supplemented with 1% cholesterol and raw or processed vegetables.

Fructus Ligustrum lucidi inhibits inflammatory mediator release through inhibition of nuclear factor-kappaB in mouse peritoneal macrophages.

Fructus Ligustrum lucidi (FLL) is a widely used herbal medicine for the treatment of a variety of pathologies. We have investigated the anti-inflammatory mechanism of FLL in mouse peritoneal macrophages. FLL exerted an anti-inflammatory action through inhibition of lipopolysaccharide (LPS)-induced tumour necrosis factor (TNF)-alpha production in mouse peritoneal macrophages.
