MAN 365enzyme levels increase rapidly after the onset of shock. It is possible that corticmtemid application would be most effective when used prim to insult as, indeed, Weissman and others(8) haw demonstrated in other sthockproducing traumas.Summary. Hydrocortisone administered to tourniquet traumatized rats, in infusion fluids, was effective in lowering the levels 04 betaglucuronidase in the serum. H o m e r , survival in hydmrtisune-infused animals was less than in saline-infused animals. Moreover, an effective infusate containing Cohn Fraction I1 of lyophilized, reconstituted, human plasma did not significantly alter the level of (betaglucuronid'ase in the blood. Hycimcmtisone, as given in these experiments, proved an ineffective agent for resuscitation f m tourniquet shock. Serum levels of beta-glucuronidase, presumed to reflect lysol.wmal enzyme release, did not correlate with survival.

A Bayesian image processing (BIP) formalism which incorporates a priori amplitude and spatial probability density information was applied to two-dimensional source fields. For valid, moderately restrictive a priori information, strikingly improved results for ideal and experimental radioisotope phantom imaging data, compared to a standard non-Bayesian formalism (maximum likelihood, ML), were obtained. The applicability of a fast Fourier transform technique for "convolution" calculations, a reduced-region restriction for the initial "deconvolution" calculations, and a relaxation parameter for accelerating convergence are considered.
