A 6-trial version of the verbal Selective Reminding Test was administered to 56 adults, ages 18 to 58 years, with no prior neurological or psychiatric history. Norms are reported for all scores generated by the test.
Only one report on the neuropsychological sequelae of attempted hanging exists in the English language. Two cases of attempted hanging with subsequent isolated memory deficits are reported. Possible mechanisms for induction of this amnesia are discussed. In these two cases it is most likely that circulatory disturbance produced by the ligatures caused ischaemic hippocampal damage, which in turn led to amnesia.
The present study investigated whether there are significant differences in the responses of individuals of varied social class background to selected TAT cards. White, female college students (N = 70) were classified as "working class" or "middle class" according to the characteristics of their families of origin and were asked to write stories in response to five TAT cards. Significant differences between the TAT stories written by the two social class groups were found for pattern of dependency and locus of control. No significant differences were found in number of drive expressions, intensity of drive expressions, or level of defenses used. Implications of these results for testing, as well as the difficulties in studying psychological phenomena across social class, are discussed.
Quantitative differences in subjects' responses to selected TAT cards were studied. 70 white, female college students wrote stories in response to TAT Cards 1, 2, 3BM, 12M, and 13MF. Stories were scored for several measures of drive intensity, defensive pattern, and object relational pattern. On all measures, the several cards were associated with different patterns of response. The use of the pattern of scores on several cards (as opposed to aggregate measures summing responses to several cards) for exploration of the ebb and flow of various aspects of intrapsychic functioning is discussed.

There is a real and conscious need for hospital workers to have meaningful work and to be adequately recognized for this work, both materially and in terms of respect and status within the institutions in which they are employed. These needs are frustrated by the conditions of work in the large modern hospital. Two main stabilizing forces, operating in part on different sets of workers, prevent hospital workers from collectively asserting their needs against the hospital's priorities. For the unskilled and semiskilled workers there are forces which lead to a typical industrial work ethic-alienation from the content of their work. For the skilled workers, there is the ideology of professionalism. The result is an increasing division of the nonmanagerial hospital work force into two groups with opposing class identifications: a proletarianized body of semiskilled and unskilled workers and a large group of skilled workers who are allowed to participate, through the ideology of professionalism, in the real status of the doctors.
In devising a new procedure for the isolation of Golgi fractions from rat liver homogenates, we have taken advantage of the overloading with very low density lipoprotein (VLDL) particles that occurs in the Golgi elements of hepatocytes approximately 90 min after ethanol is administered (0.6 g/100 g body weight) by stomach tube to the animals. The VLDLs act as morphological markers as well as density modifiers of these elements. The starting preparation is a total microsomal fraction prepared from liver homogenized (1:5) in 0.25 M sucrose. This fraction is resuspended in 1.15 M sucrose and loaded at the bottom of a discontinuous sucrose density gradient. Centrifugation at approximately 13 x 10(6)g.min yields by flotation three Golgi fractions of density >1.041 and <1.173. The light and intermediate fractions consist essentially of VLDL-loaded Golgi vacuoles and cisternae. Nearly empty, often collapsed, Golgi cisternae are the main component of the heavy fraction. A procedure which subjects the Golgi fractions to hypotonic shock and shearing in a French press at pH 8.5 allows the extraction of the content of the Golgi elements and the subsequent isolation of their membranes by differential centrifugation.
The three Golgi fractions isolated from rat liver homogenates by the procedure given in the companion paper account for 6-7% of the protein of the total microsomal fraction used as starting preparation. The lightest, most homogeneous Golgi fraction (GF(1)) lacks typical "microsomal" activities, e.g., glucose-6-phosphatase, NADPH-cytochrome c-reductase, and cytochrome P-450. The heaviest, most heterogeneous fraction (GF(3)) is contaminated by endoplasmic reticulum membranes to the extent of approximately 15% of its protein. The three fractions taken together account for nearly all the UDP-galactose: N-acetyl-glucosamine galactosyltransferase of the parent microsomal fraction, and for approximately 70% of the activity of the original homogenate. Omission of the ethanol treatment of the animals reduces the recovery by half. The transferase activity is associated with the membranes of the Golgi elements, not with their content. Galactose is transferred not only to N-acetyl-glucosamine but also to an unidentified lipid-soluble component.
In order to understand better the physiological adaption of creosotebush (Larrea divaricata Cav.) to drought conditions, its carbohydrate and nitrogen metabolism after a 7-day desiccation period under controlled conditions were studied. Although fructose was not significantly altered in the leaves of desiccated plants, as compared to those maintained under normal moisture conditions, both glucose and sucrose were significantly reduced. Total amino acids more than doubled under moisture stress, the increase being predominantly due to proline, phenylalanine, and glutamic acid. Significant increases also occurred in alanine, arginine, histidine, isoleucine, and valine. Increases or decreases in other amino acids were not significant. These stress-induced changes in certain amino acids are considered in relationship to protein hydrolysis, to accumulation of nitrogen degradation products translocated from the roots, and to the possible function of specific amino acids (e.g., proline) in NH(3) (+) storage.
