Single and double wavelength excitation of laser-induced fluorescence of normal and atherosclerotic peripheral vascular tissue.

Laser-induced fluorescence spectra were recorded from the exposure of peripheral vascular tissue to both helium-cadmium and argon-ion laser radiation. Spectral analysis was based on simple algebraic expressions constructed using the intensity difference of the various spectral regions. The above methods were developed in order to determine the degree of atherosclerosis according to the laser-induced fluorescence signal. Similar results with single wavelength excitation were observed during in vivo irradiation of peripheral vessels.

Effect of liquid-nitrogen and formalin-based conservation in the in vitro measurement of laser-induced fluorescence from peripheral vascular tissue.

In order to investigate the effects of conservation in liquid nitrogen and formalin on peripheral vascular tissue (abdominal aortic, femoral, flank, ham, fibular and tibial artery tissue), laser-induced fluorescence spectra have been recorded during the exposure of these tissues to helium-cadmium and argon ion radiation. The spectral distribution of tissue fluorescence allows the development of simple algorithms based on the intensity difference in order to discriminate the tissue samples when they are fresh and after they have been stored for 24 and 28 h in liquid nitrogen or formalin.

Traumatic cholecystectomy.

Avulsion of the gallbladder from its liver bed with detachment from both cystic duct and artery is an exceedingly rare consequence of blunt abdominal injury. A case is reported in which early recognition by diagnostic peritoneal lavage led to successful treatment.
