In normal rats changes in the enterocytes that appear to be associated with physiological cell death were found. They were confined to the villous tip and included fragmentation of the microvilli and increased electron density of the cytoplasm with morphological alterations of the organelles. Acute severe zinc deficiency in young rats results in degenerative changes in the enterocytes and microvillous damage which is not confined to the villous tip. Increased numbers of apoptotic bodies as a result of cell death are found. The enterocyte lesions differed from cell death preceding normal desquamation. There were no significant changes in Paneth cell ultrastructure. These results were compared with the ultrastructural findings reported in patients with Acrodermatitis Enteropathica.

The metabolic effect of ventromedial hypothalamic (VMH) lesions, which are known to cause hyperphagia and obesity, has been studied in rats kept on a controlled light and food regimen. The animals were sacrificed at 4 different times during the second postoperative day. A feeding-induced hypersecretion of insulin was found in the VMH-lesioned animals. It was accompanied by a marked hypoglycemia as compared to the control groups during the feeding period. The glycogen content of liver and diaphragm in the lesioned groups is increased as compared to the controls during the same period. The VMH-lesioned animals showed hypertriglyceridemia both in the fed and fasted state, whereas the postabsorptive plasma levels of free fatty acids and glycerol were decreased. An increased level of urea was observed in all lesioned groups. This is in accordance with the demonstrated protein catabolism which follows VMH lesions.

“…Sans l'exiger directement, l'ARPA influença l'adoption et la mise en place de TCP/IP qui devint un élément vital de l'infrastructure de Netville. L'adoption de TCP/IP comme une « norme » eut lieu lorsque Berkeley Software Distribution (BSD) lança UNIX 4.2 qui intégrait TCP/IP (24). BSD mit son logiciel à la disposition des autres institutions de recherche au coût de distribution, assurant ainsi la diffusion rapide de sa réalisation TCP/IP auprès des administrateurs systèmes informatiques universitaires qui connaissaient déjà l'UNIX de BSD et lui étaient favorables (25).…”
