[Pharmacodynamic equivalence and clinical trial of a new fluorocarbon-free glycerol trinitrate pump spray with low ethanol content in comparison to a fluorocarbon-containing reference spray and a fluorocarbon-free pump spray with high ethanol content].

The pharmacodynamic equivalence of a fluorohydrocarbons-(FCH)-free glyceryl trinitrate (GTN, CAS 55-63-0)-containing pump spray with low ethanol content (Nitrolingual-Spray N; TL) versus a conventional FCH-containing GTN spray (Nitrolingual-Spray, R) as reference and a FCH-free GTN pump spray with high ethanol content (TH) was investigated by digital plethysmography (DPG) in a double-blinded, placebo-controlled (TL-matched placebo spray), randomized, period-balanced, 4-way cross-over design. Additionally the clinical tolerability (as perceived by the subjects and reported to the treatments-administrating investigator) was determined. The DPG-changes (cla; ratio of c-incisure and systolic a-wave) after the sublingual (s.l.) administration of 0.8 mg GTN of TL were biostatistically equivalent with R: the confidence intervals (CI) of the point estimates of the maximal decrease in cla (TL/R: 0.98, 90%-CI: 0.84 to 1.14) and the area-weighted average decrease in cla (TL/R: 0.97, 90%-CI: 0.80-1.16) were well in a 80-125% tolerance range. The time of occurrence of the maximal DPG-effect of TL was not different from R (distribution-free estimate of the difference TL-R: -2.25 min, 95%-CI: -9.5 min to 2 min). In contrast the maximal DPG-effect of TH after the s.l. administration of 0.8 mg GTN had a statistically significant earlier onset (TH-R: -6 min, 95%-CI: -9.5 min to -2 min) and a higher area-weighted average response (TH/R: 1.12, 90%-CI: 0.95 to 1.34). TH consistently caused an utterly unpleasant burning sensation in the mouth, thus this perceived local discomfort was distinctly different compared to all other treatments.(ABSTRACT TRUNCATED AT 250 WORDS)

Frequency of day residue in dreams of young adults.

The percentage of dreams with day residue that could be identified by the dreamer, without free associating to the dream, was observed for a sample of 44 men and 44 women college students. The men identified day residue in 46.6% of their dreams and the women identified day residue in 48.9% of their dreams. The results were discussed in the context of Freud's idea that, while every dream likely has day residue, only some dreams have residue that can be identified without first free associating to the dream.

The Color-A-Person Body Dissatisfaction Test: stability, internal consistency, validity, and factor structure.

Stability, internal consistency, validity, and factor structure of the Color-A-Person Body Dissatisfaction Test (CAPT) were assessed. Two- and 4-week test-retest correlations for college students and alpha coefficients for students and eating-disorder patients ranged from .70 to .89. Factor structure was unaffected by gender and clinical status. Correlations were mostly between -.40 and -.60 with Rosenberg's (1965) Self-Esteem Scale and Secord and Jourard's (1953) Body Cathexis Scale (BCS). Men higher on Body Mass Index (BMI) liked upper body parts; women higher on BMI disliked lower body parts. Treatment for bulimia affected both body image tests comparably.

Rorschach evaluation of adolescent bulimics.

It has become apparent that the excessive dieting engaged in by many girls when they reach puberty frequently serves as an impetus for the later development of eating disorders. While the existence of bulimia nervosa has been well documented in late-adolescent girls, only minimal research has been devoted to delineating the personality characteristics that distinguish bulimics from normal adolescents. The present study utilized the Rorschach to contrast 12 DSM-III-R diagnosed adolescent bulimics with 12 female adolescent controls. Exner's (1986) Comprehensive System was used for scoring the protocols. Statistically significant group differences were detected on both the overall Depression and the Schizophrenia Indices, as well as on several subcomponents of each. Additionally, bulimics averaged a greater number of aggression responses. The data suggested that the adolescent bulimics were more depressed, self-punitive, and negativistic than their peers, and that they had more disordered thoughts, inaccurate perceptions, and impaired judgment. The cognitive disturbances were not limited to the areas of food and weight. The results are alarming for this young population, particularly since the severity of symptoms certainly will increase over time if left untreated. Recommendations are made for early symptom identification and intervention.

Adenocarcinoma of the gallbladder in two siblings.

The authors present two siblings with adenocarcinoma of the gallbladder. This is the third report on familial occurrence of such disease. The cancer was diagnosed at age earlier than usual. One of the patients did not have gallstones. The literature is reviewed. Remarks are made about the relationship between heredity and cancer.

Fine points aside: data are data.

Movement responses by 5 1/2- to 6 1/2-year-old children on the Holtzman Inkblot Test were reported on by Lockwood et al. in volume 45 of this Journal. Criticism of the findings discussed in that article by J. Swartz, Reinehr, and C. Swartz was published in the December, 1981, volume of the Journal. The present article rebuts their criticism and emphasizes the significance of the original findings which reflect new and highly discrepant normative M response data from that previously available.

Two studies of the movement responses in young children: new and highly discrepant norms.

The Holtzman Ink Blot Test was administered to 5- to 6-year-old children and analyzed for movement response. The range and frequency of movement response in both an original and replication study are significantly greater than would have been anticipated for this age group based upon available normative data. NO significant differences were found in the frequency of Human Movement and Animal Movement responses. No sex difference among subjects was found in the range and frequency of movement responses produced. These new findings call into question previously reported data as well as some of the theoretical presumptions underlying the production of movement responses by young children.

Effects of fantasy behavior, level of fantasy predisposition, age, and sex on direction of aggression in young children.

The effect of fantasy behavior, fantasy predisposition, age, and sex upon direction of aggression in children was assessed in 57 kindergarten boys and girls. Ss from low to high levels of assessed fantasy predisposition were randomly designated as experimental or control. All Ss were exposed to an imposed frustrating condition. The experimental group was then exposed to a condition designed to elicit spontaneous fantasy behavior; the control group was exposed to a condition designed to be incompatible with fantasy. All Ss were then assessed for direction of aggression. Children who engaged in fantasy behavior following frustration were significantly more extrapunitive than control Ss (p less than .05); the findings did not support either the premise that fantasy results in drive-reduction or that fantasy results in the turning inward upon the self of hostile drive manifested by increased intropunitiveness. Age was found to be significantly but negatively correlated with extrapunitiveness (p less than .05).

Relationships between sons' feelings of being understood by their fathers and measures of the sons' psychological functioning.

Factor analysis of a questionnaire designed to measure a son's feeling of being understood by his father is reported. The questionnaire, which contained 12 paragraphs each purporting to be an aspect of the son's feeling of being understood by his father, was administered in small groups to a sample of 413 male college students along with three indices of son's level of general functioning--a self-concept scale, a somatic complaints inventory, and the degree of help-seeking behavior. Five interpretable factors were extracted from the data. The meaningfulness of the factors was substantiated by their significant correlations with certain of the other measures administered to the sample. Three of the factors were correlated positively (p less than .01) with Ss' self-concept, while two were correlated negatively (p less than .01) with the number of somatic complaints by the Ss'.

Ego modalities in the manifest dreams of male and female Chicanos.

When the manifest dreams of young adult male and female Chicanos were examined through an inventory which captures the dream content and pattern, striking differences between male and female dreams were found in the areas of setting, characters, interaction, self, instinctual modalities, and realism. Generally speaking, the men's internal psychic world, as viewed through their dreams, tended to be organized around a highly visible and demarcated self seen as robustly active, randomly in motion, and often contentiously involved with unrelated others. The confines of this internal world were sketched in as broad, but were occupied by boundaries and barriers and were often subject to unpredictable events. In contrast, the women's internal world contained a relatively less sharply defined and less robustly active self, but also a less contentious self with a greater range of interactions with more, and more familiar characters. Narrower confines were matched by less emphasis on boundaries, greater predictability, and more goal-directed locomotion.
