RESUMO

Background@#Insulin is a peptide hormone that regulates post-prandial physiology, and it is well known that insulin controls homeostasis at least in part via the central nervous system. In particular, insulin alters the activity of neurons within the autonomic nervous system. However, currently available data are mostly from unidentified brainstem neurons of the dorsal motor nucleus of the vagus nerve (DMV). @*Methods@#In this study, we used several genetically engineered mouse models to label distinct populations of neurons within the brainstem and the spinal cord for whole-cell patch clamp recordings and to assess several in vivo metabolic functions. @*Results@#We first confirmed that insulin directly inhibited cholinergic (parasympathetic preganglionic) neurons in the DMV. We also found inhibitory effects of insulin on both the excitatory and inhibitory postsynaptic currents recorded in DMV cholinergic neurons. In addition, GABAergic neurons of the DMV and nucleus tractus solitarius were inhibited by insulin. However, insulin had no effects on the cholinergic sympathetic preganglionic neurons of the spinal cord. Finally, we obtained results suggesting that the insulininduced inhibition of parasympathetic preganglionic neurons may not play a critical role in the regulation of glucose homeostasis and gastrointestinal motility. @*Conclusion@#Our results demonstrate that insulin inhibits parasympathetic neuronal circuitry in the brainstem, while not affecting sympathetic neuronal activity in the spinal cord.

RESUMO

Primary malignant melanornn of the vagina is rare, with only about 130 reported cases worldwide. They presumably arise from melanocytes that are present in the vagina in 3% of normal wornen. Vaginal melanoma accounts for less than 1% of melanomas and less than 3% of primary malignant tumors of the vagina. Most of patients complain vaginal bleeding, vaginal discharge, foreign body sensation in order. The best treatment of vaginal melanoma rernains eni.gmatic, Many authors indicate that radical surgery may be the pcferred approach and the number of reported cases treated with radical surgery is increasing. But other author comment that no significant change in survival is apparent with radical surgery. Overall prognosis is poor as most patients have deeply penetrating lesions at the time of diagnosis. Recently, not only the effort to increase the survival rate but the quality of life including sexual function after treatment is becoming an important issue about treatment ot cancer patients. We experienced a case of primary malignant melanoma of the vagina treated with radical surgery and restored the sexual function by vulvovaginal reconstruction using gracilis myocutaneous flap. So we report this case with brief literature review.
