ABSTRACT
The microarchitecture of the pangolin's stomach favouring the high chitinous diet has been less waived into, despite extensive morphological investigations. Histological analysis of the microanatomy will provide powerful tools for interpretation to yield reliable insights. We investigated this by fixing the tissues in 10 percent formol saline for histological analysis. Serial sections at 5 micron m thickness were subjected to general staining methods for light microscopic study (Haematoxylin and eosin, Van Gieson's and Verhoeff's). The results revealed basic structural arrangements in their coats, with a modification of the epithelial lining of cardia and fundus into stratified squamous keratinized epithelium. These modifications were also reflected in the distribution of collagen and elastic fibers in the various layers (coats) of the stomach. The present study has shown that there was an adaptation of the stomach of African tree pangolin to its diet as reflected in the microarchitectural configuration.
RESUMEN
La micro arquitectura del estómago de los pangolines que favorece la alta dieta de chitinous sido poco tomada en cuenta, a pesar de las amplias investigaciones morfológicas. El análisis histológico de la microanatomía proporcionará herramientas de gran importancia para la interpretación, junto con dar una información confiable. Se investigó mediante la fijación de los tejidos en solución salina de formol al 10 por ciento para análisis histológico. Las serie de secciones fueron sometidos a métodos de tinción estándar para el estudio con microscopía de luz (hematoxilina y eosina, Van Gieson y Verhoeff s). Los resultados revelaron adaptaciones estructurales básicas en sus capas, con una modificación del revestimiento epitelial del cardias y fundus en epitelio escamoso estratificado (queratinizado). Estas modificaciones también se reflejan en la distribución de colágeno y fibras elásticas en las diversas capas del estómago. El presente estudio ha demostrado que es una adaptación del estómago a la dieta como se refleja en la configuración de la microarquitectura.
