"From Wesley's original group of items, the authors selected 12 that did not seem to overlap and which they consider to be satisfactory for a rigidity measure." The items are presented. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The mean antral immunoreactive gastrin (IRG) concentration of 38 duodenal ulcer (DU) patients was significantly higher (35-9+/-5-2 mug/g) than that of 21 controls (15-9+/-2-6 mug/g). Also the mean IRG concentration in the proximal duodenal mucosa of 15 DU patients (3-2+/-0-8 mug/g) was higher (but not significantly) than that of 10 controls (1-8+/-0-5 mug/g). The number of G-cells in the antral mucosa of 58 DU patients and in the duodenal mucosa of 29 DU patients was not larger than that of controls. The distribution of immunoreactivity in gastrin components has been investigated in the antral and duodenal mucosa of six DU patients and six controls. In the antral mucosa the mean percentage of G-17 was 93-3% in DU patients and 92-0% in controls. G-34 amounted to 4-0% in DU patients and to 5-0% in controls. The G-34 percentage in the duodenal mucosa was higher (however not significantly) in the DU patients than in the controls (50-1% versus 35-8%). Ultrastructurally, the antral G-cells of DU patients had a significantly lower density index of their secretory granules suggesting higher functional activity. It is concluded that the exaggerated serum IRG response of DU patients to different stimuli is not a consequence of an increased G-cell mass.  相似文献

Intravenous administration of 125I-hCG to 7-8 day pseudopregnant rats resulted in maximum uptake of radioactivity to corpora lutea 2 hours after treatment. At this time tissue/plasma radioactivity ratios on an equal weight basis were: corpora lutea, 70.2 +/- 12.8; ovarian interstitium, 4.6 +/- 0.2; kidney, 2.2 +/- 0.1. No appreciable uptake was seen by adrenals or liver. Radioactivity in corpora lutea was associated primarily with membranes which sedimented at 2000g and when released by heat it was more than 63% bound to luteal LH receptor preparation in vitro. Radioactivity in renal tissue was associated primarily with the 100,000g supernatant fraction and was bound less than 1% to luteal LH receptors in vitro. PGF2alpha significantly reduced uptake (p less than .001) of 125I-hCG by corpora lutea within 30 minutes (-63%) as well as at 1 (-64%), 2 (-75%), 4 (-68%) and 24 hours (-85%). No clear effect of PGF2alpha on uptake of 125I-hCG by ovarian interstitial tissue was seen. Plasma progesterone was significantly decreased (p less than .001) within 30 minutes (-47%; p less than .01) after PGF2alpha treatment and also at 1 (-65%), 2 (-82%), 4 (-68%) and 24 hours (-92%). Two hours after PGF2alpha treatment the content of progesterone in corpora lutea was depressed (-46%; p less than .001). It is suggested that the rapid inhibition of luteal progesterone production induced by PGF2alpha in vivo occurs through a block in gonadotropin uptake by corpora lutea.  相似文献

The third documented case of primary squamous cell carcinoma of the urachus in the English literature is reported. The interesting coincidental occurrence of the dermoid cyst of the right ovary and a complete longitudinal septum of the vagina and uterine cervix is described.  相似文献

Several lines of inquiry have led to the expectation that an infant's response to an unfamiliar adult might be influenced by the degree of control that the infant is able to exert over the situation. 24 male and 24 female infants (9.5–10.5 mo old) participated in a study in which the initial appearances of a stranger were contingent (controlled by the infant), noncontingent and frequent, or noncontingent and infrequent. Ss' subsequent reactions were assessed within the context of a stranger-approach sequence and a free-play situation. Initially, Ss responded more positively to the approaching stranger if her appearances were either controllable or frequent than if she appeared infrequently. As the stranger intruded, however, she was responded to more favorably by Ss in the contingent condition than by those in either noncontingent group. Analyses of free-play behavior yielded comparable results but only for female Ss. Results support the view that contingent feedback serves to mediate the formation of early social relationships.

A measure of hypnotically-induced anxiety was correlated with scores on Taylor's Manifest Anxiety Scale and Barron's Ego-Strength Scale. A positive relationship was elicited between degree of experienced anxiety and the Taylor scale; a negative relationship between anxiety and Barron's scale. "These results suggest that the MAS is a valid indicator of clinical anxiety… [and] that the… [Barron scale] is genuinely measuring ego-strength or some similar trait associated with psychopathological conditions."
