| Enteric nervous plexuses have been the object of several studies, specially the myenteric plexus whose studies describe its organization, functions and alterations. On the other hand, the submucosal plexus has been less studied and still needs descriptive studies. To analyze morphologically and quantitatively submucosal neurons of the jejunum of 90-day-old healthy rats using different techniques for neuronal staining as a way to provide normality data to compare with future experimental studies. Whole mount preparations of the jejunum were submitted to Giemsa, NADH-diaphorase and NADPH-diaphorase techniques to stain the total neuronal population, more metabolically active subpopulation and subpopulation of nitrergic neurons, respectively. Neurons of the... |

| Nitric oxide has several biological roles and nitric oxide synthase (NOS) is expressed in the nervous system, and co-localizes with NADPH-diaphorase. The superficial layers of the superior colliculus (SC), which receive retinal and cortical inputs, present NADPH-d staining in a sub-population of neurons that include all cell types. We have previously shown, by NADPH-diaphorase, that eye enucleation alters the intracellular distribution of NOS. Here, we studied the effect of cortical ablation on NOS expression by neurons in collicular superficial layers. Our results show that cortical ablation alters the proportion of different NOS-positive cell types, but not the intracellular distribution of the enzyme. |

| Although insects lack the adaptive immune response of the mammalians, they manifest effective innate immune responses, which include both cellular and humoral components. Cellular responses are mediated by hemocytes, and humoral responses include the activation of proteolytic cascades that initiate many events, including NO production. In mammals, nitric oxide synthases (NOSs) are also present in the endothelium, the brain, the adrenal glands, and the platelets. Studies on the distribution of NO-producing systems in invertebrates have revealed functional similarities between NOS in this group and vertebrates. We attempted to localize NOS activity in tissues of naïve (UIL), yeast-injected (YIL), and saline-injected (SIL) larvae of the blowfly Chrysomya... |
