Abstract:
:Recent epidemiological studies have demonstrated a correlation between regular aspirin (acetylsalicylic acid) use and decrease risk for the development of fatal colorectal cancer. An increase in the size of the cell proliferation compartment in colorectal crypts has been correlated with an increased risk for the development of colon cancer in animals and in humans. To determine if acetylsalicylic acid acts to decrease the size of the cell proliferation compartment, young (3 month) and old (22 month) rats were treated intragastrically with: 1 the vehicle for acetylsalicylic acid delivery (0.25% wt/vol carboxymetylcellulose in 0.15 N (HCl), 2 a single dose of acetylsalicylic acid (100 mg/kg), or 3 acetylsalicylic acid (30 mg/kg) given daily for 30 days. One day after the last treatment, colons were resected, fixed, sectioned and mounted on slides for immunohistochemical staining with a monoclonal antibody to proliferating cell nuclear antigen to assess cell proliferation parameters in the colonic crypts. The results were subjected to three way analysis of variance to assess the effects of: 1 rat age, 2 acute or chronic acetylsalicylic acid treatment, and 3 location of crypts over and away from aggregates of lymphoid nodules on the crypt proliferative parameters. Results demonstrated that: 1 acetylsalicylic acid treatment caused on overall decrease in the proliferative zone height, as measured in number of cells in the crypt column, 2 that crypts located over aggregates of lymphoid nodules had significantly higher proliferative activity than crypts located away from aggregates of lymphoid nodules, and 3 after chronic acetylsalicylic acid treatment there was a greater suppression of proliferative zone height in the crypts of old rats than in the crypts of young rats. In conclusion, acute and chronic intragastric delivery of acetylsalicylic acid caused an overall downward shift in the cell proliferation compartment of colonic crypts of young and of old rats. Whether or not acetylsalicylic acid administration will cause the same proliferative zone height response in carcinogen-treated rats is not yet established.
