cGMP-dependent protein kinase I (cGKI) induces relaxation of smooth muscle via several pathways that include inhibition of intracellular Ca(2+) signaling and/or involve activation of myosin phosphatase. In the present study, we investigated these mechanisms comparatively in colon and jejunum longitudinal smooth muscle from mice. In simultaneous recordings from colon muscle, 8-bromo-cGMP (8-Br-c...
Background: Food intake of rats increases during pregnancy. This requires changes in the structure of the small intestine to absorb additional food. The aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. Materials and Methods: Duodenum, jejunum and ileum of 18 pregnant Sprague-Dawley rats (day 7, 14 and 21 pregnancy) ...
Rats maintained with parenteral nutrition following 60% jejunoileal resection plus cecectomy exhibit minimal adaptive growth in the residual jejunum but a dramatic adaptive growth in the residual colon. Coinfusion of insulin-like growth factor I (IGF-I) with parenteral nutrition induces jejunal growth but has minimal effects in the colon. Our objective was to study the role of the endogenous IG...
Objective: Several studies have shown the antispasmodic activity of Matricariarecutita without detailing the underlying mechanism(s). The present study was designed to determine whether the antispasmodic mechanisms of M. recutita extract mediated via histaminergic/cholinergic receptors, Ca2+channels, activation of PKA2 and NO release in isolated rabbit jejunum. Methods and Materials: The concen...
The experiment was conducted to evaluate the effect of antibiotic, organic acid, probiotic and prebiotic on performance and small intestinal morphology in male Ross 308 broiler chicks for 42 days in tropical conditions. The study was completely randomized design with 5 treatments, 4 replicates and 8 chicks per each. The treatments were: T1: basal diet, T2: diet containing antibiotic oxytetracyc...
Abstract Feed is the most expensive input in commercial pork production. In order to reduce feed costs, using high-fiber ingredients has become a common practice. Moderate levels of fiber can maintain intestinal physiological function and promote health. Oxidative stress linked impaired nutrient absorption growth performance. This study investigated effects (HF, 6% crude fiber) low-fiber (LF, 3...
