The present study was aimed to investigate the morphology and histomorphometry of stomach and gastric mucosa in western grey kangaroo (Macropus fuliginosus). The stomach was composed of three indistinctive separate parts namely sacciform forestomach, tubiform forestomach, and hindstomach. The tubiform forestomach was the main tubular section of the organ. The stomach had a compound lining. The ...

Intragastric administration of 3-methylcholanthrene (MCA) has been reported by others to cause cancers of the glandular stomach and large intestines in an inbred strain of Syrian golden hamsters. In search of the molec ular basis of this process, this study examined the diver sity of the macromolecules and carcinogen-protein com plexes in colon and glandular stomach cytosols during the long-ter...

The modifying effects of 24R,25-dihydroxyvitamin D3 [24R,25(OH)2D3], a vitamin D3 derivative, on glandular stomach carcinogenesis were investigated in male Wistar rats by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and sodium chloride exposure during the postinitiation phase. A total of 130 male 6-week-old rats was divided into five groups. Groups 1-3 (consisting of 30 rats/group) were given MN...

The equine stomach consists of two separate non-glandular and glandular sections. Despite the incidence most lesions in region, both parts are prone to lesions. In this study, 41 hybrid-native horses, including 24 stallions 17 mares, were examined over five years. total, 27 horses (65.85%) that sampled had lesions, erosion, granuloma, or on region stomach. Occurrence gastric erosive granulomato...

During the development of the proventriculus (glandular stomach) of the chicken embryo, the endodermal epithelium invades into the surrounding mesenchyme and forms glands. The glandular epithelial cells produce pepsinogen, while the non-glandular (luminal) epithelial cells secrete mucus. Sonic hedgehog is expressed uniformly in the proventricular epithelium before gland formation, but its expre...

The aim of this study was to investigate the structure and ultrastructure of the digestive tract of Qinling lenok (Brachymystax tsinlingensis Li, 1966), a cold water Salmonidae fish, an endangered teleost species, with high potential for controlled rearing in Shaanxi Province of China, by light and electron microscopy. Morphological data of the digestive tract are important for understanding fi...

Fifty male and fifty female Spargue-Dawley rats were randomly chosen and used to study the sexual dimorphisms of stomachic histological structures. The rat stomach consisted of the nonglandular part and the glandular part. The gender differences of the nonglandular part existed in the thicknesses of the stratified squamous epithelium and the longitudinal muscle. These findings revealed that the...
