[Endemic goiter in the La Kara region (Togo). Analysis of etiologic factors].

Among 6,035 people living in 3 villages from the area of La Kara (Togo), 984 randomized subjects were investigated to evaluate goiter prevalence and related etiologic factors. Creatinine and thiocyanates (SCN-) were measured in urine, thyroid hormones and TSH in plasma. Iodine was evaluated in urine, water, salt, soil, millet and sorgho.

[Immunocytochemical characterization of neurosecretory systems producing mesotocin and vasotocin in the brain of several Lacertidae].

Using immunofluorescent techniques vasotocin (VT) and mesotocin (MT) neurosecretory systems were identified in the brain of Lacertidae: one european species and of two south-algerian species. In the 3 species MT and VT was shown to be synthetized in specific neurons located in the anterior preoptic area (POA), the supraoptic (SON) and in the paraventricular (PVN) nuclei. The axons originating in SON and PVN were ending either in the external zone of the rostral median eminence (ME) near to the adenohypophysial portal vessels, or in the neural lobe.
