azoxymethane (see Ref. 15). One explanation to account for the difference between colon and small intestine is the fact that the intestinal flora (1, 5, 12) and the bile acids (1, 2, 8, 9) can influence the incidence of colonic tumors. Colonic tumors can be induced, however, in germ-free rats (1, 5, 12) and in segments of rat intestine distal to a colostomy (14). It appears,therefore, thatparto...

   The aim of the present study was to develop a single unit, site-specific matrix tablets of aceclofenac allowing targeted drug release in the colon with a microbially degradable polymeric carrier, chondroitin suphate (CS) and to coat the optimized batches with a pH dependent polymeric. The tablets were prepared by wet granulation method using starch mucilage as a binding agent and HPMC K-100 ...

Simple luminal obstructions of the large and small colon are relatively common causes of colic in horses, and are caused by feed impaction, sand accumulation, fibrous foreign body ingestion, nonstrangulating displacements, and or enterolith formation. Many horses with large colon and small colon feed impactions respond to medical treatment, including withholding feed, administering fluid therap...

Research on colon-targeted polymers delivery systems is ongoing for conditions such ulcerative colitis, Crohn's disease, colon cancer, as well the of peptide or protein medications and vaccines. For colon-specific disorders in particular, focused nano-drug to helpful because nanoparticles can build up sick areas, improve therapeutic efficacies, allow localized therapies, which lower systemic to...

Sturgeon is one of the most important species of the Caspian Sea aquatics. Unfortunately, this species faces the threat of extinction today. This makes specific studies on any type of sturgeons more important than before. Studies like histological studies, radiology, and sonography, all require a complete understanding of the anatomy of this fish. Since pilot studies showed some misconceptions ...

VS1 bearing T ceils comprise the major population of 3'/8 T cells in the human intestinal tract. To gain insight into mechanisms involved in the generation of these cells and the diversity of their repertoire, we have characterized the junctional sequences of V81 T cell receptor transcripts in the human small intestine and colon. Mucosal biopsies obtained from defined regions along the length o...

cystic lymphangioma is a rare benign tumour occurring during childhood. this tumour, caused by lymphatic system malformations, commonly occurs in head and neck regions. herein, we report the case of a three-month-old male infant, diagnosed with a large cystic mass in the abdominal cavity and groin. the infant presented with low-grade fever and significant abdominal distension. abdominal ct scan...
