ABSTRACT
In the current study, the histological structure of the gallbladder of Alburnus tarichi (Güldenstädt, 1814) was investigated. Hematoxylin and eosin were used to stain the histological sections for routine examinations, in addition to using periodic acid Schiff (PAS) for the neutral mucins, aldehyde fuchsin (AF) for the sulphated mucins, and Alcian blue (AB; pH 2.5) for the acidic mucins. In addition, proliferating cell nuclear antigen (PCNA) immune-staining was performed for the detection of dividing cells among the epithelium. The gallbladder of A. tarichi was composed of mucosa, muscularis, and serosa or adventitia layers. The mucosa covering the wavy pleomorphic folds was made up of tall columnar epithelium and a lamina propria. The apical surface of the epithelial cells was lined by continuous short microvilli. On the epithelium, the luminal surface was remarkably stained with PAS, AF, and AB. Slight to moderate staining was observed on the epithelial cells in the apical zone with PAS. The cytoplasm of epithelial cells were stained in a slight manner with AF. No goblet cells were observed among the epithelium. According to the PCNA immune-staining, some epithelial cells were observed to proliferate. The lamina propria consisted of loose connective tissue that contained fibrocytes, collagen and elastic fibers, capillaries, and small blood vessels. The muscularis layer displayed muscle fibers that were circular, smooth, and surrounded by collagen fibers. The subserosal and serosal or adventitial layers had typical morphology to those of other fish and vertebrates.
RESUMEN
En este estudio, se investigó la estructura histológica de la vesícula biliar de Alburnus tarichi (Güldenstädt, 1814). Las secciones histológicas se tiñeron con Hematoxilina-Eosina para los exámenes de rutina, además de usar el ácido periódico de Schiff (PAS) para las mucinas neutras, aldehído fucsina (FA) para las mucinas sulfatadas y azul alcián (AB; pH 2,5) para las mucinas ácidas. Además, se realizó una tinción inmune de antígeno nuclear de células proliferativas (PCNA) para la detección de células en división entre el epitelio. La vesícula biliar de A. tarichi estaba compuesta de capas, mucosa, muscular y serosa o adventicia. La mucosa que cubría los pliegues pleomórficos ondulados estaba formada por un epitelio columnar alto y una lámina propia. Se observó una superficie apical de las células epiteliales revestida por microvellosidades cortas y continuas. En el epitelio se observó una tinción importante de la superficie luminal teñida con PAS, FA y AB. Se observó una tinción leve a moderada en las células epiteliales en la zona apical con PAS. El citoplasma de las células epiteliales se tiñó ligeramente con FA. No se observaron células caliciformes entre el epitelio. Según la tinción de PCNA, se observó que proliferaban algunas células epiteliales. La lámina propia consistía en tejido conectivo laxo que contenía fibrocitos, colágeno y fibras elásticas, capilares y pequeños vasos sanguíneos. La capa muscular mostraba fibras musculares circulares, lisas y rodeadas de fibras de colágeno. Las capas subserosas y serosas o adventicias tenían una morfología típica a la de otros peces y vertebrados.
