Histomorphometric evaluation of dromedarian (Camelus dromedarius) heart

The primary objective of present study was comprehensive exploration of age related cardiac anatomy of camel which might be helpful for appropriate understanding of CVDs. Seven hearts of each, young (1–2 years) and adult (>5 years), group were collected and dissected for macroscopic and microscopic evaluation. Tissue sections were prepared by paraffin tissue technique and morphometry was done using Image J ®. Means of all parameters were compared by student T-Test. In macroscopic evaluation relative weight of heart was found significantly (P<0.05) higher in young dromedaries while absolute weight, circumference, thickness of left ventricle wall, width of moderator band and thickness of aortic wall along with lumen were found significantly (P<0.05) higher in adult dromedaries. Microscopic parameters of heart like thickness of endocardium, sub-endocardium and the purkinje fibres diameter were found significantly (P<0.01) thicker in adults than young dromedaries; however, it was otherwise for sub-endothelium. Parenchymal percentage in myocardium was found significantly (P<0.01) lower in young than adult dromedaries, however, the stromal content followed the inverse pattern. These cardiac anatomical results can be implicated for legitimate understanding of CVDs.
