The effects of electrolytic lesion of the septum on the theta activity of the dorsal hippocampus were studied in the chronically implanted Rat during wakefulness and paradoxical sleep. The experimental results show that depending on its localization, septal lesion can either: (1) eliminate the wakefulness theta rhythm without suppressing that of paradoxical sleep; (2) eliminate the paradoxical sleep theta rhythm without suppressing that of wakefulness. These results suggest that there are two kinds of theta activity having different anatomophysiological bases and a different functional significance: one associated with wakefulness and the other with paradoxical sleep.

The authors describe the results obtained in an examination by isoelectrofocusing of more than 1,000 serum samples from various regions in France. The autochthonous populations of the north side of the Pyrénées are characterized by a high frequency of the gene Gc2 and a very low frequency of the Gc1F gene. This distinguishes them from the other groups studied (southwestern, northwestern and eastern France). The quantitative analysis of the data emphasizes the difference. These results can only be explained by the interdependance of the genetic and metabolic factors.

Comparison of 5 antiinflammatory drugs and placebo in a double blind, short term, cross-over trial conducted in patients suffering from rheumatoid arthritis. 15 measurements were used and studied. With classical unidimensional statistical tests it was not possible to discriminate active drugs between them. Multidimensional analysis (correspondance analysis and discriminant analysis) are more sensitive and allow us to distinguish active drugs with only 11 criterion.

I and i antigens were detected by indirect immunofluorescence on human erythrocytes. 80% of the cord blood cells were brightly fluorescent with anti-i, 15% only with anti-I. In adult blood, this ratio is reversed, 2% only of the cells being intensively labelled with anti-i. The percentages characteristic of adult blood are established within the first 8 months of life.

Microinjections of low concentration of morphine (5 micrograms) into the nucleus Raphé Magnus of the Rat produce a strong analgesia that can be reversed by systemic naloxone, an opiate antagonist. The administration of naloxone (5 micrograms) into the Raphé Magnus considerably reduces the effects of intravenous morphine. The effects of microinjections of morphine are strongly reduced by Cinanserin, suggesting a role for serotoninergic mechanisms in morphine analgesia.

A possible GABAergic innervation of the nucleus raphe dorsalis (NRD) was investigated by measuring glutamate decarboxylase activity in the NRD after lesioning the afferents of this nucleus. The slight decrease found in the enzymatic activity suggests that these afferents have a minor participation in the GABA innervation of the NRD and implies the existence of an intrinsic GABAergic system in this nucleus. This local innervation was demonstrated by radio-autography and shows fibers, axonal varicosities and cell bodies which accumulate 3H GABA in the caudal part of this nucleus.
