چکیده
Received: 07/12/2013 Revised: 20/12/12013 Accepted: 22/12/2013 Abstract The present study was conducted to observe the gross and microscopic changes in gastro-intestinal tract during helminth infestation in camels. Grossly, abomasum showed varying degrees of ulceration, congestion of mucosa, thickened walls and oedematous folds associated with haemorrhagic foci due to presence of Haemonchus spp. worms. Histopathologically, abomasum revealed hyperemic mucosa and the hyperplasia of the glands with cellular infiltration mainly of lymphocytes and eosinophils. Small intestine infected with Strongyloides spp. and Trichostrongylus spp. worms showed oedematous and congested mucosa with few petecheal haemorrhages. Histopathologically, the loss of villi, thickened mucosa and heavy infiltration of inflammatory cells in the mucosa and sub-mucosa of the duodenum were observed. Large intestine infected with Trichuris spp. revealed thickened and oedematous mucosa with focal haemorrhages. There was ulcer and nodule formation with thickening of the caecal wall. Microscopically, intestine revealed catarrhal inflammation and necrosis of gland with eosinophilic infiltration. The results revealed that the overall prevalence of helminthic infection was 68.01 per cent.

There have been numerous efforts to formulate insulin into an oral dosage form. The major problems involved with the oral administration of insulin are acidic and enzymatic decomposition by the gastric medium, and poor absorption in the small intestine due to its macromolecular structure. This study attempted to test the enhancing ability of two absorption enhancers, sodium glycocholate (Na-G...

Microencapsulation as one of the most modern methods has remarkable effects on probiotic survival. In this study Lactobacillus casei (ATCC 39392) and Bifidobacterium bifidum (ATCC 29521) were encapsulated using calcium alginate-gelatinized starch, chitosan coating and inulin via emulsion technique, and were incubated in simulated gastric juice (along with pepsin, pH=1.5) and simulated intestina...
