Iris pigmentation and behavioral inhibition.

Abstract

Two independent investigations of the association between the temperamental dimensions of inhibition and lack of inhibition to the unfamiliar, on the one hand, and the degree of pigmentation of the iris, on the other, revealed a statistically significant relation in Caucasian children between behavioral inhibition to the unfamiliar and blue irises and uninhibited behavior and brown irises. Several biochemical interpretations of this association were discussed and it was suggested that these behavioral styles might be influenced by biological factors that are partially marked by eye color in Caucasian populations.

Endocrine function is not impaired in patients with a continuous MicroMed-DeBakey axial flow pump.

OBJECTIVES: Pulsatile blood flow has been regarded to be of importance for the regulation of endocrine organs. A new generation of continuous flow mechanical blood pumps is now available for clinical application. Patients with implanted MicroMed-DeBakey axial pumps show nonphysiologic low-pulsatile blood flow profiles, and therefore it appeared to be of interest to evaluate their possible effect on the endocrine system. METHODS: Eight male patients and 1 female patients (mean age, 51 +/- 10 years) with end-stage left-sided heart failure were implanted with a MicroMed-DeBakey axial pump. After a mean period of 67 +/- 19 days, basal pituitary hormone concentrations and their responses to a bolus injection of hypothalamic releasing hormones were tested. In addition, thyroid hormones, testosterone, and plasma and urinary catecholamine levels were measured at baseline. RESULTS: Administration of the hypothalamic releasing hormones revealed normal responses of all pituitary hormones (adrenocorticotropic hormone, thyroid-stimulating hormone, luteinizing hormone, and prolactin), except for growth hormone, the response of which was slightly impaired (10.2 +/- 6.8 vs 19.9 +/- 6.5 ng/L, P < .05). Also, the cortisol response to the corticotropin-releasing hormone-stimulated adrenocorticotropic hormone release was normal, as were basal concentrations of thyroid hormones (triiodothyronine, thyroxine, free triiodothyronine, and free thyroxine), testosterone, and urinary catecholamines. CONCLUSIONS: Implantation of a continuous flow axial pump with low-pulsatile blood flow profile appears to have no major effect on the hypothalamic-pituitary-endorgan system and sympathoadrenal functions. This finding is reassuring for the growing number of patients treated with this convenient new pump and could contribute considerably to their prognosis and quality of life.

Alteration of hormone and neurotransmitter production in cultured cells by high and low frequency electrical stimulation.

HFS has become a widely used method in functional neurosurgery. However, its mechanism is not well understood, and its cellular and molecular effects have not yet been investigated. The aim of the study was to understand which cellular events, unrelated to the network organization of cells or neurons, participate in the mechanism of action of HFS. In vitro cellular effects of high (HFS) and low (LFS) frequency electrical stimulation on prolactin secretion in GH3 cell lines (prolactinoma), as well as the catecholaminergic secretion on PC12 cells (pheochromocytoma) were investigated. Cells were cultured in dishes with integrated electrodes to deliver stimulation at the same parameters as those used in clinical conditions to treat advanced forms of Parkinson's disease. Prolactin production was measured in GH3 using a Radio-Immuno-Assay. Dopamine, epinephrine and norepinephrine were measured in PC12 using Enzymo-immuno-assays. HFS for 24 hours reduced prolactin secretion by 40.3%, dopamine by 32.7%, epinephrine by 18.1% (non significant) and norepinephrine by 27.0%. LFS did not induce significant changes. These results suggest that HFS has an inhibitory impact on the cellular machinery responsible for hormone and neurotransmitter production. In this model of isolated cultured cells, network interactions and particularly presynaptic actions are discarded. HFS has inhibitory effects on cellular mechanisms responsible for the production and release of molecules participating in intercellular communication. This HFS-induced inhibition might participate in the lesion-like effect of therapeutic HFS in the basal ganglia during various movement disorders.
