Intracellular characteristics and responses of taste bud and lingual cells of the mudpuppy.

Intracellular recordings of membrane potentials of mudpuppy lingual cells were made with micropipette electrodes. Three types of cells were distinguished by their responses to chemical stimulation. Surface epithelial (SE) cells outside of taste buds responded with large membrane potential and resistance changes to a variety of stimuli representing the four taste qualities.

International maternity care monitoring: results of a pretest.

This report gives the preliminary results of a pretest cosponsored by the International Fertility Research Program and the International Federation of Gynaecology and Obstetrics. It includes data on 33 116 deliveries in 20 maternity centers in Latin America, Europe, Africa and Asia. The findings are organized around four themes: (a) family formation and reproductive history, (b) family health, (c) management of this delivery and (d) desired family size and family planning practices.

[Evaluation of one year experience with cerebral tomodensitometry in pediatric neurology].

Cerebral tomography allows the delineation of areas modified by edema or necrosis, the visualization of calcifications undetectable by standard x-ray examination, extra- or intra-cerebral blood effusions and neoformations of the cerebrum or of its envelopes. It also reveals slight or localized cerebral atrophies that other neuro-radiologic techniques sometimes failed to detect. It appears therefore worthwhile to reconsider pediatric neurology according to this new type of investigation.

Computerized tomography in the study of West's syndrome.

37 children presenting with West's syndrome were studied by computerized tomography scanning. An abnormality consisting of diffuse cerebral atrophy, predominating in the fronto-temporal region, was demonstrated in 30 cases. The abnormality was sometimes associated with calcification (tuberous sclerosis) or malformation (agenesis of the corpus callosum).

[Conduction abnormalities in Kearns-Sayre syndrome. Observation of 2 clinical cases].

The authors describe 2 cases of Kearns-Sayre Syndrome associated with conduction defects. In one case permanent pacing was performed. The progressive development of severe conduction defects warrants close follow-up.

Hospital counseling in Khartoum: a study of factors affecting contraceptive acceptance after abortion.

This study examines the impact of contraceptive counseling on 3 263 women hospitalized in Khartoum for treatment of incomplete abortion. The analysis which focused on education and parity/child desire, revealed that the counseling program produced contraceptive acceptance among 47.0% of those followed up.
