This volume contains six substantial and informative reports covering the current status of therapy with various agents. One of these outlines the Red Cross program for determination of the place of human serum albumin in the treatment of patients having edema associated with renal diseases. Another details the usefulness of the new morphine derivative, metopon® hydrochloride (methyl dihydromorphinone hydrochloride). A group of three, reporting on organomercurial preparations, begins with a statement pointing out that as used these are bacteriostatic rather than bactericidal; questions are raised concerning their efficacy. Two supplemental reports, dealing with mercurochrome® (merbromin) and merthiolate® give evidence for these preparations but do not fully satisfy the question raised. The other status reports referred to are Protein and Amino Acid Preparations, a monograph, Streptomycin in the Treatment of Tuberculosis and Teropterin® and Diopterin® in the Treatment of Cancer, all valuable summaries or contributions in the subjects concerned.
