[Morphology of the posterior colliculus in epileptic hamsters]. / Comportamiento morfológico del colículo posterior en hamsters epilépticos.

In an inbred strain of Golden hamsters with audiogenic seizures, we have studied the collicular participation, planning a morphologic study of posterior colliculus central nucleus. The parameters used have been: number of neurons and glia, neuronal areas and area of all the colliculus. The measurement and the counts have been done in both sides and for to validate the results we have used an A.N.O.V.A.. In the epileptic group, there are a less number of neurons and a major correlation Nucleus/cytoplasm. The left-right correlations are positive for the neurons, while in the control group are for the glia. Although, the number of neurons in the epileptic animals are less, this are more active, which can be related to the participation of the colliculus in the audiogenic seizures.

Effect of vagotomy on the conjugated bile acids in the dog.

The effects of truncal vagotomy and selective gastric vagotomy on the conjugated bile acids and rations T/G and Tri/Di have been studied in twenty dogs. The results show that truncal vagotomy has no effect on the conjugated bile acid values determined in the 4th and 16th week. The ratio T/G increased while the Tri/Di decreased in the 16th week. The selective gastric vagotomy only shows a change of the taurocholic acid levels which are lower than the control levels in the 4th week.

[Effect of vagal denervation on the alkaline phosphatases of the jejunal mucosa of the rat (author's transl)]. / Efecto de la denervación vagal sobre las fosfatasas alcalinas de la mucosa yeyunal de la rata

The results of experiments conducted on the qualitative (histochemical) and quantitative (biochemical) determination of alkaline phosphatase present in rat yeyunum mucosa. Normal and vagal denervated animals were used. Results indicate that there are no significant enzymatical changes after vagal extirpation.
