A monoclonal antibody (niAli) was prepared against a semipurifÃ-ed preparation of an organ specific neoantigen (OSN) reactive in the leu kocyte adherence inhibition (LAI) assay. The tnAb (LC20.1) induces a positive LAI response when incubated with leukocytes of normal individ uals in the presence of OSN derived from either human colon or lung carcinoma cell lines. Absorption of crude OSN prepar...

Motility recording of small and large intestine was performed in old Wistar rats divided into three groups: (a) standard diet, (b) standard diet plus a symbiotic preparation, and (c) standard diet plus a heat-inactivated symbiotic preparation. SCM-III. significantly increased the myoelectric activity of small intestine and colon (p < 0.01 versus [a] and [c]) paralleling "young" values of 4-mont...

A monoclonal antibody (mAb) was prepared against a semipurified preparation of an organ specific neoantigen (OSN) reactive in the leukocyte adherence inhibition (LAI) assay. The mAb (LC20.1) induces a positive LAI response when incubated with leukocytes of normal individuals in the presence of OSN derived from either human colon or lung carcinoma cell lines. Absorption of crude OSN preparations...

Colon cancer is the second leading cause of cancer-related death in the Western world. Approximately 80-90% of colon cancers develop in adenomas after mutations. The risk of encountering malignancy increases with the size of the adenomatous polyp. It is approximately 1% in adenomas <1 cm, and increases to 10% for adenomas 1-2 cm, and 20-53% for adenomas >2 cm. CT colonography (CTC) is a new tec...

OBJECTIVE Enema administration in the morning of routine colonoscopy is known to be useless. However, the potential bowel cleansing effects of distal colon emptying with enema prior to purgatives are not known. The aim of this study is to investigate the effects of enema use before purgatives in preparation for colonoscopy. MATERIAL AND METHODS Two hundred twenty-seven patients were randomly ...

BACKGROUND AND STUDY AIMS Neoplastic lesions can be missed during colonoscopy, especially when cleansing is inadequate. Bowel preparation scales have significant limitations and no objective and standardized method currently exists to establish colon cleanliness during colonoscopy. The aims of our study are to create a software algorithm that is able to analyze bowel cleansing during colonoscop...

To determine the safety and cost-effectiveness of outpatient preoperative bowel preparation with polyethylene glycol-electrolyte lavage solution, we retrospectively analyzed 726 cases of colectomy done by colon and rectal surgeons between July 1987 and July 1991. Included were 319 patients who had elective segmental or total abdominal colectomy with primary anastomosis. Patients who required pr...

Clear liquids are often part of colonoscopy preparation instructions, regardless of the active cleansing agent. Poor understanding of this facet may yield poor preparation with delays in management. We studied comprehension of this facet of colon preparation in an Appalachian population. Our survey contained demographic items and a list of food items from which subjects could select clear liqui...

the demand of colonoscopy has been increasing rapidly due to the social interest for screening of colorectal cancer (CRC). This phenomenon is associated with the fact that colonoscopy is the most useful method for the detection and removal of colorectal polyps and that colonoscopic polypec-tomy significantly reduces the incidence and mortality of CRC. Although there are several screening modali...
