LAURA CALKINS 《Bioethics》2010,24(1):27-34
Using medical literature citations, Congressional hearings, and declassified documents this paper examines the uses of pharmaceuticals in the interrogation of vulnerable populations. From the use of IV relaxants on criminal suspects during the 1920s to the Global War on Terror, the nexus of drugs, testing, and interrogations will be explored in both the domestic and international contexts.  相似文献

Atropinesterase was found to exist in approximately one out of every four rabbits, and no relation could be observed between the incidence of the enzyme and season, sex, color, age, or weight. The occurrence of the enzyme was also shown to be unrelated to that of cholinesterase. The distribution of atropinesterase in the blood and organs of rabbits was studied; the animals devoid of the enzyme in their blood contained no demonstrable activity in any of the organ extracts tested. The presence of atropinesterase in frog liver, and its absence from the serum, has been confirmed. Hydrolysis of homatropine, but not atropine, by guinea pig liver was observed, while the serum was without action on either of the compounds. On this basis the possibility arises that guinea pig liver contains a homatropinesterase enzyme separate from atropinesterase. It was shown that lack of atropinesterase activity in certain rabbits is not likely to be due to the presence of a naturally occurring inhibitor. It has been demonstrated that contrary to previous indications neither fresh egg white nor yolk possess atropinesterase activity. The specificity of tropinesterases was investigated and evidence was presented for the possible existence of two distinct enzymes, cocainesterase and tropacocainesterase.  相似文献

The lipides of the diverticula of Asterias forbesi have been studied by histochemical and biochemical means. Correlations between results obtained by histochemical examination of sections, and chemical analysis of isolated lipide have been made, particularly with respect to phosphatides, steroids, and aldehyde lipides. The results of the histochemical study were in good agreement with the chemical data as to the nature of the phosphatide fraction, the presence of acetone-soluble aldehyde lipides, and the composition of the free droplet fat. Homogenized diverticula were differentially centrifuged in order to establish the distribution of types of lipides in the various cellular components. In addition, data have been presented which demonstrate a direct correlation between the titer of α-glycerol ethers and that of acetone-soluble lipide acetals in the unsaponifiable fraction.  相似文献

There are four different kinds of protein in blood serum as shown by the solubility curves. They must be either single proteins, several continuous series of compounds, or solid solutions. The solid protein phases are hydrated. There are definite sex and species differences.  相似文献
