A single infusion of Perilla ketone (PK) into sheep causes marked increases in lung fluid and solute exchange in the absence of any alteration in either pulmonary arterial or left atrial pressures. These alterations are most compatible with increased pulmonary microvascular permeability. The present
A model of increased microvascular permeability pulmonary edema was developed in chronically instrumented unanesthetized sheep using perilla ketone (PK). PK did not cause changes in pulmonary hemodynamics but did cause marked increases in the flow of protein-rich lung lymph. The changes in lung
We investigated the anti-arthritic effects of the radiation mutant Perilla frutescens var. crispa leaf extract (SFE-M) and wild type leaf extract (SFE-W), both prepared by supercritical carbon dioxide (SC-CO2) extraction, on collagen antibody-induced arthritis (CAIA) in
Perilla frutescens or purple mint has been associated with atypical interstitial pneumonia (AIP) for a quarter of a century. The amount and the stage of the plant required to produce AIP have been much debated. A field case in which catastrophic loses occurred in cattle ingesting hay containing
Oral administration of the perilla leaf extract (PLE) to mice inhibits inflammation, allergic response, and tumor necrosis factor-alpha production. We also found that PLE suppressed the tumor necrosis factor-alpha (TNF-alpha) production in vitro. Using the inhibitory activity of TNF-alpha production
In this study, we attempted to identify and assess effects of isoegomaketone (IK) isolated from Perilla frutescens var. crispa on the development of rheumatoid arthritis (RA). RA was induced in male Balb/c mice by collagen antibody injection. Experimental animals were randomly divided into five
Perilla ketone (PK) is a potent lung toxin that causes increased microvascular permeability pulmonary edema in grazing animals. Because the mechanism of action of PK is not know, we investigated whether PK directly affects endothelial cells. Bovine aortic endothelial cells were grown to confluence
We studied the effects of three different doses (15, 20, and 25 mg/kg) of Perilla ketone (PK) on the blood-perfused in situ sheep lung while obtaining external measurements of lung transvascular protein flux. Lymph flow and lymphatic protein clearance increased significantly after all doses of PK.
The anti-inflammatory and anti-allergic activity of perilla leaf extract was investigated. The oral administration of perilla leaf extract to mice inhibited two types of acute inflammatory models, arachidonic acid-induced ear edema and 12-o-tetradecanoylphorbol-13-acetate-induced ear edema. Oral
