The subjects used were 10 of the same IS Negro male~ former drug addicts who served· tn the experiments dea J ing wtth the acute effects of BAS. These patients rece tved the following drug combfnatlons in a randomized order (latin square): BAS placebo plus LSD placebo; BAS plus LSD placebo; BAS placebo plus LSD; and BAS plus LSD. Doses of BAS were ISO mg. every stx hours for four doses (total dose 600 mg.J. The last dose was given two hours before LSD. LSD was admtnlst~red orally in doses ranging between 0.5-1.5 mcgm./~g. (~verage of 1.1 mcgm./kg.). The smaller doses were gtven to the men who were tested ftrst stnce tfie posstbil tty exlsted that BAS and LSD might s yne rgl ze. , ., Methods. The methods used Included determination of' pupillary size~ threshold f'or knee jerk, resting ,. systolic blood pressure, .. response to a modtf'tcatton of f the Abramson-Jarvflc questionnaire, and evaluatlo~ of' the -- cltnJcal grade of the LSD reaction based on short psychiatric examinations. These methods and the means of stattstteal analysts employed have been previously described In other reports. The results are shown In the accompanying table. The onfy Important change noted was stgnJf'Icant blocking of' LSD Induced elevation in blood pressure by the BAS. All other aspects of' the reaction. Including mental response, were unaffected. A number of patients withdrew from all experiments after these tests were completed, primarily because of long persistence of the unpleasant BAS effects. Discussion. The results do not favor the hypothesis that LSD psychosis Is due to potenttatton of serotonin within the central nirvous system. They, however, eff~cts do not exclude this poss tbt·r tty since we do not know whether the symptoms caused by BAS are due fo per iphera r or to .. ·c~n~ral acttons. . . - • ...... .. ; , .. .

This document contains a table that presents data on the attempted blocking of LSD reactions with BAS (Brom-DMA). The table has columns for different drug conditions (BAS PLACEBO + LSD PLACEBO, BAS + LSD PLACEBO, BAS + LSD, BAS PLACEBO + LSD) and rows for observed effects like pupillary reflex, pupillary size, systolic blood pressure, number of questions, and clinical grade. Handwritten annotations are present, including "A-347" in the top right corner. The page also includes typed text below the table providing details on the dosage of LSD and BAS used in the experiment, and indicating that the figures represent means of observations on 10 subjects with standard errors.

The page consists of scanned text from a document. There are no photographs, diagrams, forms, or stamps visible. The only handwritten annotation is a number "A-345" in the lower right corner. The document appears to be a report discussing observations and results of an experiment involving BOL and LSD, with a discussion section. There are no visual cues related to experimental procedures or equipment.
The document displays a table comparing the effects of different drugs (BOL and LSD) against a placebo, measuring various physiological and psychological responses. The table includes columns for "PLACEBO," "BOL," and "LSD," with rows detailing "Stellar Reflex," "Pupillary Size," "Stolic Blood Pressure," "Number of Questions," and "Clinical Grade." Handwritten annotations, including a number "1-344" in the lower right corner and superscripts marking footnotes at the top of some table entries, are visible. Additionally, a title at the top states "EFFECTS OF 5-8 MG./70 KG. OF D-2-BRUM-LYSERGIC ACID DIETHYLAMIDE." Three numbered footnotes below the table provide further context on the doses and measurement standards used in the experiment.
