Transplantation of dental pulp-derived neurosphere cells ameliorated outcomes of global cerebral ischemia. It was also demonstrated that dental pulp-derived cell administration provided some neuroprotection.
A nasogastric tube is often used along with a nasal endotracheal tube during oral surgery or dental treatment under general anesthesia. Although the insertion of a nasogastric tube is a simple procedure, it can be associated with complications that lead to potentially serious consequences. The knotting of a nasogastric tube around an endotracheal tube is rare. Here, we report a case in which the nasogastric tube became knotted around the nasal endotracheal tube in the nasopharynx. We compare this case with 4 previous similar cases and provide a theory of how the nasogastric tube might have become knotted.
The skin temperature (T m) of the orofacial area influences orofacial functions and is related to the blood flow (BF). Marked increases in BF mediated by parasympathetic vasodilation may be important for orofacial T m regulation. Therefore, we examined the relationship between parasympathetic reflex vasodilation and orofacial T m in anesthetized rats. Electrical stimulation of the central cut end of the lingual nerve (LN) elicited significant increases in BF and T m in the lower lip. These increases were significantly reduced by hexamethonium, but not atropine. VIP agonist increased both BF and T m in the lower lip. The activation of the superior cervical sympathetic trunk (CST) decreased BF and T m in the lower lip; however, these decreases were significantly inhibited by LN stimulation. Our results suggest that parasympathetic vasodilation plays an important role in the maintaining the hemodynamics and T m in the orofacial area, and that VIP may be involved in this response.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
