BACKGROUND The rat vertebrae is a good model to study bone regeneration after implantation of biomaterials used to treat bone loss, a major problem in oral and dental surgery. However, the precise characterization of bone microstructures in the rat vertebrae has not been reported. Therefore, the aim of this study was to achieve the complete analysis of such bone, at different scales, in order to have a clear model of healthy bone for comparison with regenerated bone. METHODS In order to image the cortical bone of rat caudal vertebra, confocal Raman microscopy was combined with high resolution X-ray micro computed tomography (micro-CT), with scanning electron microscopy (SEM) using backscatter electron imaging and with more conventional histology coloration techniques. SEM and Raman microscopy were done in various regions of the cortical bone corresponding to external, middle and internal areas. The spongy bone was imaged in parallel. Micro-CT was performed on the whole vertebra to monitor the network of haversian canals in the cortical bone. Osteonic canals characteristics, and relative chemical composition were analysed in several regions of interest, in cortical and spongy bone. Five rats were included in this study. RESULTS On micro-CT images, differences in intensity were observed in the cortical bone, substantiated by SEM. Chemical analysis with Raman spectra confirmed the difference in composition between the different regions of the cortical and spongy bone. PCA and k-mean cluster analysis separated these groups, except for the external and middle cortical bone. Peak intensity ratio confirmed these results with a CO3 to ν2 PO4 ratio significantly different for the internal cortical bone. Grayscale images stack extracted from micro-CT showed that global architecture of cortical bone was characterized by a dense and complex network of haversian osteonic canals, starting from the surface towards the vertebrae center. The mean diameter of the canals was 18.4µm (SD 8.6µm) and the mean length was 450µm (SD 152µm). Finally, Raman reconstructed images of the lamellar bone showed an enlargement of the lamellar layer width, both in circumferential lamellar bone and around haversian canals. CONCLUSIONS Micro-CT and confocal Raman microscopy are good tools to complete classical analysis using optical and electron microscopy. The results and measurements presented in a rat model known for its small inter-individual differences provide the main characteristics of a mature bone. This study will allow the community working on this rat vertebrate model to have a set of characteristics, in particular on the structure of the haversian canals.

INTRODUCTION Anatomy textbooks´ connection to the rigid censoring laws enacted by Habsburg rulers, was never sufficiently investigated. Using anatomy textbooks written at the University of Vienna, our article aims at investigating the influence of censorship laws on the anatomy textbooks in Vienna between 1786 and 1865. METHODS In our case study we compared legal text and archival sources (source material A) with seven prefaces of textbooks written by Viennese anatomists (source material B). The prefaces were comparatively investigated by applying the following questions based on source material A: (1) What motives for writing the textbooks were indicated by the anatomists in the prefaces? (2) What legal or other influences were mentioned as motives that point to a connection to the censorship regulations installed? (3) Referring to changing censorship guidelines is there a change in the mentioned audience? RESULTS Our results are that we found evidence for censorship regulations (source material A) in the prefaces (source material B). Also, the motives for writing those textbooks changed over time because of changing censorship regulations. CONCLUSION Our findings show that Viennese anatomy textbooks were part of the Austrian censorship laws in the investigated period with a timely correlation between the appointment as professor and the publication of the textbooks and prefaces (indirectly) referring to censorship laws. The academic tradition of writing textbooks arose from this system, when freedom of speech stood in opposition to the absolute Habsburg reign. Thus, when working with historical anatomy textbooks it is important to reflect on their censorship heritage.

BACKGROUND There is no available data on the occurrence rate of a converged alveolar canal, the detailed three-dimensional (3D) courses of alveolar canals/grooves (ACGs), or the contribution of each superior alveolar nerve to each area in the maxilla. This study aimed to clarify the 3D courses of ACGs, the relationship between ACGs and superior alveolar nerves, and the contribution of posterior superior alveolar nerves (PSANs) using computed tomography (CT) with histological analysis. METHODS During the gross anatomy course at Niigata University, we investigated nine human cadavers. RESULTS All anterior and posterior ACGs converged into the common alveolar canal, which contained blood vessels and several nerve bundles surrounded by perineurium, located at the nasal floor near the pyriform aperture. Histometrical analysis clarified that 16.3% of the nerve bundles in this canal were derived from PSANs, and 67% of the bundles were dispersed while they coursed down to the nasal floor. There seems to be no relationship between the density of nerve bundles in the canal and the number of remaining anterior teeth. CONCLUSIONS Data obtained from observing the detailed 3D courses of anterior and posterior ACGs, and their relationship with superior alveolar nerves, suggest that PSANs partially contribute to the nociception of the anterior teeth.
