Intestinal innervation and its role in mucosal damage and inflammation

The regulatory role of the autonomic nervous system (ANS) in intestinal inflammation and immunity is widely acknowledged. In this thesis, we investigated mediating pathways and demonstrated a pivotal role for the spleen. We studied the effect of electrical splenic nerve bundle stimulation (SpNS) in a mouse model of experimental colitis induced by dextran sulfate sodium and showed that SpNS reduced colitis. Further, we elucidated effects of sympathetic activity on intestinal mucosal homeostasis. Chemical sympathetic denervation through 6-hydroxydopamine led to enhanced intestinal inflammation, and impaired barrier integrity. In contrast, adrenergic receptor stimulation through UK 14,304, a specific receptor agonist, led to increased proliferation and stem cell function. Adrenergic receptor α2A was found to act as molecular delegate of intestinal epithelial sympathetic activity controlling cell proliferation, differentiation, and host defense. The ANS is a complex network activating numerous pathways and therefore effects can be ambiguous and are often challenging to interpret. Our studies increased the understanding of effects of autonomic neuronal activity on intestinal processes, and future studies should continue investigations with not only experimental, but also clinical research. Ultimately, a role for bioelectronic medicine in intestinal immunity and mucosal healing can be allocated and neuromodulatory techniques are to be examined as a plausible treatment modality

PRELIMINARY FINDINGS OF A POTENZIATED PIEZOSURGERGICAL DEVICE AT THE RABBIT SKULL

The number of available ultrasonic osteotomes has remarkably increased. In vitro and in vivo studies have revealed differences between conventional osteotomes, such as rotating or sawing devices, and ultrasound-supported osteotomes (Piezosurgery®) regarding the micromorphology and roughness values of osteotomized bone surfaces. Objective: the present study compares the micro-morphologies and roughness values of osteotomized bone surfaces after the application of rotating and sawing devices, Piezosurgery Medical® and Piezosurgery Medical New Generation Powerful Handpiece. Methods: Fresh, standard-sized bony samples were taken from a rabbit skull using the following osteotomes: rotating and sawing devices, Piezosurgery Medical® and a Piezosurgery Medical New Generation Powerful Handpiece. The required duration of time for each osteotomy was recorded. Micromorphologies and roughness values to characterize the bone surfaces following the different osteotomy methods were described. The prepared surfaces were examined via light microscopy, environmental surface electron microscopy (ESEM), transmission electron microscopy (TEM), confocal laser scanning microscopy (CLSM) and atomic force microscopy. The selective cutting of mineralized tissues while preserving adjacent soft tissue (dura mater and nervous tissue) was studied. Bone necrosis of the osteotomy sites and the vitality of the osteocytes near the sectional plane were investigated, as well as the proportion of apoptosis or cell degeneration. Results and Conclusions: The potential positive effects on bone healing and reossification associated with different devices were evaluated and the comparative analysis among the different devices used was performed, in order to determine the best osteotomes to be employed during cranio-facial surgery
