Synthesium elongatum (Brachycladiidae) is an intestinal digenean described from the finless porpoise (Neophocaena asiaeorientalis) in Japan. Few records of this species exist and there is a remarkable morphological similarity between S. elongatum and S. tursionis, such that a synonymy between the species has been suggested previously. However, no morphological and/or molecular analysis has been carried out to clarify the taxonomic status of S. elongatum. In this study, we collected specimens of Synthesium sp. from N. asiaeorientalis in western Japan. The specimens possess lobed testes within the third quarter of the body, a round ovary, and vitellaria extending to level of uterine field,whi…
NEONATAL CAPSAICIN TREATMENT DOES NOT PREVENT SPLANCHNIC VASODILATATION IN PORTAL-HYPERTENSIVE RATS
It has been suggested that the peripheral sensory neurons are involved in the splanchnic hemodynamic changes of portal hypertension. Therefore the influence of permanent ablation of sensory neurons by neonatal capsaicin pretreatment (50 mg/kg, subcutaneously) on the development of the hyperdynamic splanchnic circulation in portal-hypertensive rats was studied. In adulthood, portal hypertension was induced with partial portal vein ligation. In study 1, systemic and splanchnic hemodynamics were measured by means of a radiolabeled-microsphere technique in portal-hypertensive rats, under ketamine anesthesia, pretreated with capsaicin or vehicle. Mean arterial pressure, heart rate, cardiac index…
