THE EXPERIMENTAL VASCULAR LESIONS PRODUCED BY BACILLUS MALLEI

Prumycin produced by Bacillus cereus.

The isolation of prumycin from cultured broths of Streptomyces kagawaensis has been reported by HATA et al.') It inhibits the growth of some bacteria and fungi,') and shows antitumor action.') The structure determined by OMURA et al.3,4) to be 4-D-alanylamino-2-amino-2,4-dideoxy-Larabinose. We isolated this antibiotic from cultured broths of a strain BMG366-UF5 which was isolated from a soil sa...

Experimental vascular lesions elicited by collagenase in rats.

Purified collagenase which attacks only native collagen and gelatin was injected intravenously into the normal and DCA hypertensive rats to determine whether damage in collagenous tissue of the vascular wall would result in diffuse necrotizing lesions of the vessels. In the normal rats subclinical edema, proteinuria, and mild degenerative lesions in the small arteries and arterioles were produc...

Antibacterial Activity of the Lipopeptide Biosurfactant Produced by Bacillus mojavensis PTCC 1696

Bacillus mojavensis PTCC 1696 (a member of Bacillus subtilis group) has been isolated from the Iranian oil field (Masjed-I Soleyman), to examine its ability to produce biosurfactant (lipopeptide type) [28]. The present study was designed to characterize the antibacterial activity of th...

[Lesions produced by radiofrequency ablation of the cavotricuspid isthmus in an experimental model].

INTRODUCTION AND OBJECTIVES Experimental studies have shown that deeper and wider lesions (up to 10 mm long or deep) can be safely created using an 8 mm or irrigated tip catheter for ablation to treat atrial flutter. However, potential damage to the tricuspid valve or inferior cava vein has not been systematically evaluated. PATIENTS AND METHOD The cavotricuspid isthmus was ablated in 26 pigs...
