[Q]: Abstract: Impairment of the mucosal microcirculation may contribute to ethanol-induced gastric mucosal damage. In this report, we describe diffuse and severe ultrastructural damage to the capillaries of the gastric glandular mucosa of the rat that occurred within 1 min after intragastric instillation of 100% ethanol. There was a gradient of damage in that endothelial cell structure was most severely disrupted in profiles of capillaries located close to the luminal surface but some morphologic evidence of damage was evident in the wall of capillary profiles to a mean depth of 256 micron. Capillary structure was generally normal in the deeper regions of the mucosa. Pretreatment with intragastric cysteamine, 30 mg/100 g, or intragastric prostaglandin F2 beta, 0.5 mg/100 g, significantly reduced the depth in the mucosa to which damage to capillaries extended. Pretreatment with intragastric prostaglandin F2 beta, 0.2 mg/100 g, afforded no significant protection. We conclude that a 1-min exposure to 100% ethanol induces striking damage to the microcirculation of glandular mucosa of the rat stomach with severe damage to capillary profiles near the lumen and sparing of capillary profiles near the muscularis mucosa, and pretreatment with the sulfhydryl agent, cysteamine, or with a large dose of prostaglandin F2 beta reduces the extent of but does not abolish ethanol-induced damage to gastric mucosal capillaries.

[Q]: Abstract: Hematoporphyrin derivative, a photosensitive material used to identify and treat neoplastic tissue in humans, has been found to localize in atheromatous plaques in animals and has recently been found in postmortem human atherosclerotic plaques. It is not known whether human plaques take up hematoporphyrin derivative in vivo. In five patients undergoing surgical vascular procedures, specimens containing atheromatous plaques were removed and immediately incubated in autologous oxygenated blood at 37 degrees C with hematoporphyrin derivative at a clinically relevant concentration for 2 hours. On exposure to ultraviolet light, porphyrin fluorescence was noted throughout each plaque, whereas adjacent plaque-free tissue showed no fluorescence. To compare in vitro with in vivo hematoporphyrin derivative uptake by plaques, the fluorescence of three types of arterial lesions (induced by a high cholesterol diet, catheters or balloon injury) was studied in 16 New Zealand White rabbits. Each lesion fluoresced selectively with the same intensity whether hematoporphyrin derivative exposure was performed in vitro or in vivo. Fluorescence microscopy did not show a difference in the pattern of hematoporphyrin derivative fluorescence between in vitro and in vivo specimens. The results suggest that human atheromatous plaques should take up hematoporphyrin derivative in vivo and are, therefore, potentially suitable for photochemical treatment as a new therapeutic approach to atherosclerosis.

[Q]: Abstract: To calibrate an anesthetic mass spectrometer without the use of premixed gases and vapors in cylinders, we devised a gas mixer using fixed resistances of capillary needle tubings and adjustable needle valves to dilute test gases and vapors with oxygen. The dilution ratio was determined during each calibration by diluting air with oxygen and noting the reduction in the ratio of nitrogen to oxygen. Empiric correction was made by the computer for the effects of density and viscosity, relative to air, on the flow of nitrous oxide, carbon dioxide, and the saturated vapors of the three anesthetics through the capillary resistor. The computer was programmed to control solenoid valves both for calibration and for the multiplexed sampling of operating rooms. Oxygen, nitrous oxide, and carbon dioxide were used as pure gases, and halothane, enflurane, and isoflurane were vaporized at room temperature in 50-ml vaporizers. The resulting calibrations were found to be accurate to within +/- 2%.
