Pattern of lecithin-cholesterol-acyl-transferase (L-CAT) activity in the course of liver cirrhosis.

Considering liver cirrhosis a limit model, and therefore a condition suitable for the analysis of changes of lipid metabolism in liver disorders generally, the authors examined the L-CAT pattern, total and free cholesterol, HDL-cholesterol and APO-A in sixty-five subjects; fifty-three were suffering from liver cirrhosis, and were subdivided into those who were diabetic in addition, and those who were not, as well as according to the severity and duration of the liver disease; the remaining twelve were healthy controls. Analysis of the findings showed L-CAT to diminish significantly as the metabolic changes due to liver injury worsen. Contrary to the other parameters studied, L-CAT was the only one for which significant changes were found on analysis of variance comparing non-diabetic cirrhotics of varying severity. Further comparison suggested the idea that the reduction of L-CAT activity was correlated to the rate of progression of the disease rather than to the temporary condition of compensation or decompensation, so much so as to suggest itself as a valid parameter for the prognosis of liver cirrhosis.

[Polymerization exothermal reaction of dental prosthetic resin for temporary crowns. A comparative evaluation].

BACKGROUND: The aim of the present study is to evaluate the risk of a possible thermal stress of the pulpal tissue during the fabrication of a temporary crown when using the direct technique. METHODS: For this study, 7 different brands of acrylic resin including Acrylic type and Bis-Gma type have been tested. At this purpose one series of in vitro experimental trials were performed. The trials have evaluated the temperature increase inside the pulp chamber of an extracted tooth during the fabrication of a provisional crown. The temperatures reached by the resins tested were measured using a digital thermometer connected with a thermal probe. RESULTS: The temperatures measured during the experimental trials show a different ability by the 7 tested resins to produce heat. Indeed, while the polymethylmethacrylate resins show higher increments rate of temperature, the Bis-Gma resins produce less dramatic increase along with lower temperatures peaks. CONCLUSIONS: Testing the 7 different resins has proved that there is an actual risk to cause lesions to the pulpal tissue during the placement of a provisional crown when using the direct technique. The materials which show a reduced exothermal reaction are: IsoTemp and Protemp II.
