Inhibition of normal growth by chronic administration of delta-9-tetrahydrocannabinol. 1971

F J Manning, and J H McDonough, and T F Elsmore, and C Saller, and F J Sodetz

Body weight, food and water intake, and feces weight of 20 albino rats were recorded daily for 70 days. On days 11 to 40, 12 rats received behaviorally effective doses of Delta-9-tetrahydrocannabinol, either orally or intraperitoneally. These rats ate significantly less than placebo-dosed controls during the treatment period, and gained significantly less weight. Food intake recovered in the 30-day posttreatment period, but the former drug group still weighed less than the controls on day 70. In addition, all rats who had received intraperitoneal injections of Delta-9-tetrahydrocannabinol showed evidence of chronic diffuse nonsuppurative peritonitis.

D010538 Peritonitis INFLAMMATION of the PERITONEUM lining the ABDOMINAL CAVITY as the result of infectious, autoimmune, or chemical processes. Primary peritonitis is due to infection of the PERITONEAL CAVITY via hematogenous or lymphatic spread and without intra-abdominal source. Secondary peritonitis arises from the ABDOMINAL CAVITY itself through RUPTURE or ABSCESS of intra-abdominal organs.

D010919 Placebos Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.
