[Retroesophageal right subclavian artery. Description of a clinical case]

A case of retroesophageal right subclavian artery, occasionally observed in a patient submitted to diagnostic investigation and surgical treatment for bilateral steno-obstructive involvement of the carotid district, is described.

[Importance of intraoperative H/R ultrasonography in the immediate evaluation of the results of thromboendarterectomy of the carotid bifurcation]

Personal experience on the intraoperative use of HR echography for the evaluation of the immediate surgical results in carotid bifurcation T.E.A. is reported. It is already assessed that early failure in vascular surgery is due to technically incorrect procedures.

Phallotoxin-visualization of F-actin in normal and chromium-poisoned Euglena cells

The presence of F-actin in Euglena cells was revealed by the use of fluorescent delta-aminophalloin. In normal cells F-actin forms a web of fine filaments at the cell periphery and around the nucleus. In Cr-poisoned cells this pattern is completely altered, and F-actin is visible as a single strongly fluorescent band of various shape and location.

Fungal toxicity of phosfon D and its reversion by lipids

The growth retardant Phosfon D inhibits the growth of some yeasts and human pathogenic filamentous fungi. The toxic effects of the compound on the dermatophyte Microsporum cookei were completely reversed by adding ergosterol and oleic acid to the medium. The significance of these findings is discussed.
