Effects of Active Hexose Correlated Compound on the Seasonal Variations of Immune Competence in Healthy Subjects
Effect of iodide on Fas, Fas-ligand and Bcl-w mRNA expression in thyroid of NOD mice pretreated with methimazole
Nonobese diabetic (NOD) mice and a derived strain, NOD.H.2h4, have been used as a model for experimental spontaneous thyroiditis and thyroiditis induced by iodide excess after a goiter-inducing period. Some authors have proposed that iodide, given after methimazole or propylthiouracil, is capable of inducing apoptosis in thyroid cells and that anti-thyroid drugs can modulate the expression of apoptosis components such as Fas and its ligand (Fas-L). Here we evaluated the effect of potassium iodide (20 µg/animal for 4 days, ip) given to NOD mice at the 10th week of life after exposure to methimazole (1 mg/ml) in drinking water from the 4th to the 10th week of life. Fas, Fas-L and Bcl-w expression were analyzed semiquantitatively by RT-PCR immediately after potassium iodide administration (group MI44D) or at week 32 (MI32S). Control groups were added at 10 (C10) and 32 weeks (C32), as well as a group that received only methimazole (CM10). An increase in the expression of Fas-L and Bcl-w (P<0.01, ANOVA) was observed in animals of group MI44D, while Fas was expressed at higher levels (P = 0.02) in group C32 (72.89 ± 47.09 arbitrary units) when compared to group C10 (10.8 ± 8.55 arbitrary units). Thus, the analysis of Fas-L and Bcl-w expression in the MI44D group and Fas in group C32 allowed us to detect two different patterns of expression of these apoptosis components in thyroid tissue of NOD mice

Pharmacological countermeasures to spaceflight-induced alterations of the immune system
Human bioastronautic programs have grown during the last 50 years. Medical and physiological findings from these missions have demonstrated that spaceflight impacts almost all physiological systems, including bone demineralization and reduced immunological competence. These adaptive responses can affect crew health and performance. Indeed, about half of the astronauts encountered immune dysregulations during space travels. Developing efficient countermeasures to preserve the astronaut’s immune system is therefore a prerequisite before undertaking future long-duration space missions. In this chapter, we present promising pharmacological countermeasures to mitigate that risk
