Morphometry of corpus callosum related with gender and age: magnetic resonance imaging study

The corpus callosum [CC] is an important structure of connecting the two cerebral hemispheres. The purpose of this study was to examine the morphometry of the CC of normal cases and its relationship with gender and age. Morphometric measurements of the corpus callosum were made on MR imaging in the mid-sagittal plane in 42 male and 48 female total 90 healthy subjects, age range was 6-17 year-old. Age of the cases were divided into three group as 6-9, 10-13 and 14-17 year-old. The length was measured by drawing a straight line at greatest antero-posterior diameter of CC, a perpendicular at its midline, anterior, posterior and medium segments of CC were measured. In addition as a result of these morphometric measurements index of corpus callosum [CCI] was calculated for every cases. Statistical analysis was performed by One-Way ANOVA- Tukey test, Independent Sample t test, Kruskal-Wallis test and Mann - Whitney U test. Without considering sex between the age group, antero-posterior, anterior, posterior and medium segments diamaters of CC was found statistically significance [p < 0.05] while analysis of CCI values was not found significant [p > 0.05]. These datas can be used as morphometric guide, for evaluation of the CC specially in years 6-17 age group

Morgagni hernia with pectum carinatum in a male cadaver

We present a case of 74-years old male cadaver in which morgagni hernia and associated pathologies was observed during the routine dissection. Besides the hernia, pectum carinatum, sliding hernia and hydronephrosis at the right kidney were strike findings as an associated anomalies. Morgagni hernia is the rarest one among all the diphragmatic hernias, associated with serious anomalies. Since it has a clinical importance, precise anatomical occupation and definition of this variation on a cadaver as well as the associate anomalies is being reported by comparing with other related literature, to establish occurence pattern and importance of the operational base of morgagni hernia

Development of arteriovenous anastomoses in the skins of rats during the fetal period

Para describir el desarrollo de AVAs en especies de ratas (Rattus norvegicus), los fetos fueron evaluados hasta 10 días posterior al coito. Las secciones seriadas obtenidas a partir de los fetos de ratas de 10-20 días, estuvieron sujetas a examen bajo el microscopio de luz. Varios procesos de coloración fueron aplicados sobre las preparaciones y los tipos simples de AVAs fueron determinados en la piel de los fetos, los cuales fueron observados cada día, hasta el momento del nacimiento. Las regiones con AVAs fueron fotografiadas mediante microfotografías y avaluadas. Un incremento de los músculos suaves en la estructura de la pared de anastomosis simples fue observado en embriones de 10 días hasta su nacimiento
