(12) Reactive metabolites which suppress splenic humoral immune responses are thought to be generated within the spleen rather than in distant tissues.
(13) Release of 51Cr was apparently a function of immune thymus-derived lymphocytes (T cells) because it was abrogated by prior incubation of spleen cells with anti-thymus antiserum and complement but was undiminished by passage of spleen cells through nylon-wool columns.

Definition:
(a.) Untouched, especially by anything that harms, defiles, or the like; uninjured; undefiled; left complete or entire.

(6) Intact rams exhibited GH secretory episodes of greater (P less than 0.01) amplitude than did castrated lambs.
(7) The authors conclude that H. pylori alone causes little or no effect on an intact gastric mucosa in the rat, that either intact organisms or bacteria-free filtrates cause similar prolongation and delayed healing of pre-existing ulcers with active chronic inflammation, and that the presence of predisposing factors leading to disruption of gastric mucosal integrity may be required for the H. pylori enhancement of inflammation and tissue damage in the stomach.
(8) An intact post-injury marriage was associated with improvement in education.
