Our objective was to determine the effect of arachidonylethanolamide (anandamide, AEA) injected intracerebroventricularly (icv) into the lateral ventricle of the rat brain on submandibular gland (SMG) salivary secretion. Parasympathetic decentralization (PSD) produced by cutting the chorda tympani nerve strongly inhibited methacholine (MC)-induced salivary secretion while sympathetic denervation (SD) produced by removing the superior cervical ganglia reduced it slightly. Also, AEA (50 ng/5 µL, icv) significantly decreased MC-induced salivary secretion in intact rats (MC 1 µg/kg: control (C), 5.3 ± 0.6 vs AEA, 2.7 ± 0.6 mg; MC 3 µg/kg: C, 17.6 ± 1.0 vs AEA, 8.7 ± 0.9 mg; MC 10 µg/kg: C, 37.4 ± 1.2 vs AEA, 22.9 ± 2.6 mg). However, AEA did not alter the... |

Valproic acid, an antiepileptic drug, is a well-known teratogenic agent; its main target organ is the neural tube, though organ malformations have also been described. The aim of the present work was to analyze the effects of valproic acid on embryo/fetal oral structures: Meckel's cartilage, muscles of the tongue, and submandibular gland. Rats received a intraperitoneal injected of Valproic acid (300mg/Kg) on the 10th day of their gestation. Females were sacrificed on day 20 post coitus, and fetuses were examined. No gross malformations were observed. The following morphological alterations were observed: lower body and placental weight; shorter umbilical cord length; submandibular gland parenchyma less differentiated with larger cellular cord and terminal... |
