Determination of macrophage chemotaxis to atherosclerotic plaque extract in domestic turkeys with hypertension
1990
Johnson, P.D. | Klesius, P.H. | Krista, L.M.
The chemotactic activity of turkey peritoneal macrophages in response to an atherosclerotic plaque extract from a hypertensive strain of turkeys was determined. Atherosclerotic plaque extract stimulated macrophage chemotaxis, whereas normal aortic extract did not stimulate macrophage chemotaxis. However, differences were not revealed by sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis of extracts of atherosclerotic plaque and normal aorta. Chemotactic activity was diminished with pronase treatment, suggesting the chemoattractant is a protein. Seemingly, atherosclerotic plaque of turkeys contains a macrophage chemotaxin.

This study aimed to assess the attraction effect against Lycorma delicatula and antioxidant activity of hexane, chloroform, butanol and water fraction obtained from Ailanthus altissima methanol extract. The attraction effect of chloroform fraction showed the highest activity (47%) as compared to that of other fractions. In the DPPH radical scavenging activity, methanol and butanol fraction showed higher antioxidant activity than other solvent fractions. From the above results, the potential chloroform fraction was further performed by local irritation test in New Zealand white rabbits. In eye irritation test, chloroform fraction showed moderate irritant at high concentration 0.5 g/site/mL, but there was no eye irritation at low concentration (0.05 g/site/mL). In accordance with the Draize evaluation of skin irritation, the primary irritation index was calculated to 3.3 and 0.68 at high (0.5 g/site/mL) and low concentration (0.05 g/site/ mL) causing moderate and mild irritation, respectively. On the basis of this study, Ailanthus altissima chloroform fraction could be safely considered to be a candidate of attractant against Lycorma delicatula.
