[Correlation between iodine urinary levels and pathological changes in thyroid glands].

Objectives: To determine iodine nutrition in the population and to correlate levels of iodine found in random samples of urine with pathological changes observed in thyroids collected in this population.

Materials And Methods: Urinary iodine was determined in 30 random samples of urine and the pathological study was carried out in 55 thyroid glands from corpses received by the Department of Forensic Medicine of Vitória, Espírito Santo, Brazil from May to August 2011.

Results: In 29 urine samples (96.

Long-term treatment with supraphysiological doses of nandrolone decanoate reduces the sensitivity of Bezold-Jarisch reflex control of heart rate and blood pressure.

We investigated the influence of long-term treatment with supraphysiological doses of an anabolic-androgenic steroid on the Bezold-Jarisch reflex (BJR) control of heart rate (HR) and diastolic arterial pressure (DAP), and whether this treatment induced cardiac hypertrophy. Male rats were treated with nandrolone decanoate (ND) (10 mg kg(-1) body weight for 8 weeks; DECA) or vehicle (control animals; CON). After 8 weeks of treatment, the BJR was evaluated by bradycardia and hypotension responses that were elicited by serotonin administration (2-32 microg kg(-1)).
