ISLAM, Rafiqul; AYMAN, Ummay  y  SULTANA, Nasrin. Histological Architectures and Biometric Characteristics of Indigenously Plastinated Organs of Goat. Int. J. Morphol. [online]. 2021, vol.39, n.3, pp.759-765. ISSN 0717-9502.

The histo-morphology and biometry of liver, lung and kidney of goat were studied. The obtained samples were divided into two groups. One set of tissue was processed for paraffin embedding after formalin fixation. The other set was indigenously plastinated. The plastinates were embedded with paraffin without deplastination. Both the non plastinated and plastinated tissues were sectioned and processed for routine staining. The tissues were examined under light microscope for histological architectures and quantitatively assessed the biometric parameters. The non plastinated and plastinated samples yielded mostly similar histological architectures. But plastinated liver showed alterations and artifacts with enlargement of the central vein and hepatic sinusoidal space. Plastinated lung revealed enlarged alveolar sac. Lack of nuclear clarity was observed for all the plastinated samples. The plastinated kidney revealed compactness of the cellular structures and shrinkage induced artifacts with clear renal corpuscles structure and obvious glomerular capsule (Bowman's capsule). The biometric measurements of central vein of liver, alveolar sac of lung, glomerulus and glomerular space of kidney of both plastinated and non plastinated tissue were also performed using calibrated stage micrometer. Comparison was done between the biometric data for both plastinated and non plastinated tissue. No significant difference was found in the obtained biometric data of liver and lung. Only a significant difference was observed between the width of glomerulus of non plastinated kidney and width of glomerulus of plastinated kidney. The morphological and biometric study of non plastinated and plastinated organs of goat can conclude that histological slides can be made from indigenously plastinated organs with well preserved histological architectures of the tissues with some rare exceptions. Plastination does not affect the biometric characteristics of the organs. In addition, the comparative morphologic and biometric study of plastinated and non plastinated organs of goat will be useful in education and research.
