The effect of ethyl alcohol on the laryngeal mucosa

Laryngeal mucous membranes of experimental animals (Rattus rattus L. albino) which were given 25% ethyl alcohol for 4, 10 and 20 weeks was investigated using histochemical methods. It was found that tissues were considerably damaged, especially in the areas covered by stratified squamous epithelium.     

Carbohydrate sources for ethyl alcohol production

Molasses and corn, the traditional sources of carbohydrate for the production of ethyl alcohol—for both industrial and beverage purposes—are being challenged by new sources. These were revealed by investigations undertaken during the last war emergency and by research within the industry which continues to investigate and evaluate potential sources of alcohol.     

Effect of ethyl alcohol on plasma testosterone level in mice

The effect of ethanol ingestion on testicular steroidogenesis in mice was evaluated by measuring plasma testosterone level. Four groups of CBA/J male mice were treated with one of the following doses of ethanol: 1.240, 0.620, 0.310 or 0.155 g ethanol/Kg body weight. A control group was given water. The data showed no effect of the treatment on testicular weight. The concentration of testosterone in the plasma was significantly reduced in animals treated with alcohol. There was also a significant relationship between the dose of alcohol and the plasma testosterone level, with the decrease in testosterone being from 2 to 18 fold in various groups.
