Altered protein kinase C activity in biopsies of human colonic adenomas and carcinomas.
Protein kinase C (PK-C) seems to be involved in the regulation of growth and differentiation of normal epithelial cells. Colonic adenomas and carcinomas show increased proliferation and decreased differentiation. We investigated the activity and subcellular distribution of PK-C in biopsies of normal, neoplastic, and malignant colonic epithelium to evaluate alterations in enzyme activity. In the...
متن کاملRectal Pain and the Colonic Crunch Sign
A 31-year-old man presented to a local hospital with lower abdominal and rectal pain. He reported consuming a large bag of sunflower seeds (described as chewing and sucking unshelled seeds). The day after ingestion he noted progressive abdominal pain and difficulty passing stool. Due to the pain, he attempted a self-disimpaction with inability to clear a palpable mass, prompting him to present ...
متن کاملDetermination of prostaglandin synthetase activity in rectal biopsy material and its significance in colonic disease.
A method is described for determining prostaglandin synthetase activity in milligram amounts of tissue. The procedure is based on the conversion of 14C-arachidonic acid to prostaglandin E2 and F2alpha-like substances. High levels of prostaglandin synthetase activity occurred in the inflamed mucosa of patients with ulcerative colitis and fell during successful drug therapy, but it is not yet kno...
متن کاملExtending colonic mucosal microbiome analysis—assessment of colonic lavage as a proxy for endoscopic colonic biopsies
BACKGROUND Sequencing-based analysis has become a well-established approach to deciphering the composition of the gut microbiota. However, due to the complexity of accessing sufficient material from colonoscopic biopsy samples, most studies have focused on faecal microbiota analysis, even though it is recognised that differences exist between the microbial composition of colonic biopsies and fa...
متن کاملRectal and colonic distension elicit viscerovisceral reflexes in humans.
Colonic transit is slowed in patients with disordered rectal evacuation, but the mechanism of this phenomenon is unclear. Our objective was to investigate rectocolonic inhibitory reflexes in humans to provide potential insight into patients with obstructed defecation. In 30 healthy subjects, a barostat-manometric assembly recorded colonic tone and phasic activity in the descending colon during ...
