New taxa and changes in nomenclature are provided in the genera Acmaeodera Eschscholtz, Chrysobothris Eschscholtz, and Agrilus Curtis. Acmaeodera mariposa Horn is discussed as a polytypic species, with A. dohrni Horn given subspecific status therein.

A laser-dye technique is known to injure selectively microvascular endothelium in situ. With the use of the arterioles on the surface of the mouse brain (pial arterioles), the endothelial injury is manifest by loss of several endothelium-dependent re

Pial arterioles of mice were monitored by intravital television microscopy. Responses to acetylcholine (ACh) and to McN-A-343, a selective M1 activator, were monitored before and after endothelial injury by a laser-dye technique in the presence or ab

As previously reported, NG-monomethyl-L-arginine (L-NMMA) constricted pial arterioles, inhibited dilation of pial arterioles by acetylcholine (ACh) or L-arginine (L-Arg), and enhanced platelet adhesion/aggregation at sites of endothelial damage. Howe

Minor endothelial injury was produced in pial arterioles by a laser-Evans blue technique. This technique previously has been shown to prevent relaxation of the arterioles by topical acetylcholine (ACh) or bradykinin, agonists whose actions are known

In the presence of circulating Evans blue a helium-neon laser injures the endothelium of brain surface arterioles in situ. The injury is known to selectively eliminate endothelium-dependent responses. The present study documents in mice the fact that

Pial arterioles on the surface of the mouse brain were observed via television microscopy and measured with an image-splitting technique. The vessels were dilated by L-arginine (L-Arg) in concentrations as low as 10(-5) M and were constricted in dose
