morphological and histochemical study of the abomasal epithelium in camel (camelus dromedarius) wascarried out by light and scanning electron microscopes. the lining of the abomasum was divided into fourregions, i.e. cardiac, pseudocardiac, fundic and pyloric. our investigation revealed that the cardiac andpseudocardiac regions occupy a wide part of the abomasum in camel and it reaches approxim...

are presented. There are three types: (1) straddling tricuspid orifice entering both primitive ventricles with the mitral valve entering the left ventricle (nine cases), (2) displaced tricuspid orifice into the primitive left ventricle, with no A-V orifice in the primitive right ventricle (three cases), and (3) displaced tricuspid orifice with straddling mitral valve, in which the mitral valve ...

Secoisolariciresinol diglucoside is the main flax (Linum usitatissimum) lignan that is converted to the mammalian lignans enterodiol (ED) and enterolactone (EL) by gastrointestinal microbiota. The objectives of the present study were to investigate the role of ruminal microbiota and the effects of flax oil on in vivo metabolism of flax lignans and concentration of EL in biological fluids. Four ...

Four mature rumen and abomasal cannulated wethers were used in a 2 x 2 reversal experiment to study the effect of forage quality on daily quantity of abomasal protein and microbial protein synthesis. Diets were either high quality [HOo 16.4% crude protein (CP)] or low quality (LOo 9.3% CP) Coastal bermudagrass which provided 110.7 and 58.3 g CP intake daily, respectively. Non-ammonia CP reachin...

A 10-year boy presented with a painless swelling in the left upper abdomen which gradually increased in size. Physical examination revealed a non tender, smooth, firm and an irregular mass in left hypochondrium extending to left lumbar region. On ultrasound, a hypoechoic lesion (14cm x10cm) in left suprarenal region was noted. Computed tomography (CT) revealed a large (18cm x 12cm) lobulated hy...

An experiment was carried out to investigate the dynamics of nitrogen (N) in the rumen and abomasum of rumen and abomasum-cannulated sheep using 15N dilution techniques. The 15N tracer was administered into the rumen as 15N-ammonia or 15N-labelled duckweed and the transfer of the 15N label to various N pools was followed. Flow of digesta from the rumen into the abomasum was ascertained by doubl...

1. The relationship between protein content of abomasal digesta and abomasal secretion of acid was studied in sheep fitted with re-entrant cannulas in the proximal duodenum. 2. A close relationship was found between the rate of passage of protein through the abomasum and acid secretion, both after varying the protein content of the rations supplied, and after direct introduction of proteins int...

Ultrasonography is an ideal diagnostic tool for investigating gastrointestinal disorders in cattle. In animals with traumatic reticuloperitonitis, inflammatory fibrinous changes and abscesses can be imaged. Ultrasonography can be used to assess the size, position, and contents of the abomasum. This article describes the ultrasonographic techniques used for examination of the reticulum, rumen, o...
