[Tactile and visual neglect. Preliminary study of 4 patients].

A battery of tactile tests for the study of unilateral neglect is presented with the purpose of comparing the tactile modality to the visual modality. This was applied in 4 patients with right hemisphere lesions. In 3 patients, there was evidence of neglect in both modalities with qualitatively identical anomalies. The function of spatial manipulation involved in the tasks is stressed. In the cases where both modalities were involved a supramodal hemispatial disturbance is assumed.

[Structure-mobility relationships in thin-layer chromatography. Applications to some progestogens (author's transl)].

A study has been made on the quantitative relationship between the chromatographic mobility and the structure of progestogenic steroids. The coefficient K, corresponding to the fundamental skeleton, and the parameters of different substituents were calculated from the RM values. The results obtained with eighteen steroids tested in two solvent systems of low dielectric constant and low polarity have been improved satisfactorily.
