“…Nevertheless, these immunoassays are all binding protein dependent to some extent and thereby susceptible to various interferences and uncertainties [11][12][13]. The interferences may involve drug interactions, cross-reactivity of antibodies, sensitivity to unusual binding proteins, influence of free fatty acids (FFA), and endogenous or exogenous binding inhibitors [8,[14][15][16][17][18][19][20][21][22]. Accordingly, many researchers have questioned the accuracy, validity, and reliability of direct analogue immunoassays [10,[19][20][21][22][23][24][25][26][27][28][29][30][31][32].…”

“…This inhibitory effects appear to be tonic, as administration of naloxone, an opiate receptor antagonist, to rats increases LH production (Babu et al, 1987). Reducing the opioid inhibition also facilitates the production of the GnRH surge on proestrus (Lustig et al, 1988; Masotto et al, 1990; Hashimoto and Kimura, 1991; Zhang and Gallo, 2002). This inhibition by opioids can be interpreted as increased overall suppression of GnRH and LH release or as augmentation of steroid negative feedback.…”

“…Na década de 60 surgiram vários estudos que demonstraram alterações nas dosagens séricas dos hormônios tiroidianos em patologias não-tiroidianas (14,28) . Desde então, outros trabalhos foram publicados descrevendo doenças sistêmicas agudas ou crônicas, acompanhadas ou não por desnutrição e caquexia, nas quais o perfeito entendimento da função tiroidiana não era simples, pois havia alterações dos níveis hormonais no sangue, independentemente da presença de patologia endócrina (11,12,18,37) . Anormalidades dos testes de função tiroidiana em associação com doenças hepáticas têm sido descritas por vários autores (2,4,6,15,16,25,27,28,32,33,35) em todos os níveis do eixo hipotálamo-hipófise-tiróide, assim como no transporte e metabolismo periférico dos hormônios tiroidianos.…”
