The ameliorating effect of oroxylin A on scopolamine-induced memory impairment in mice 总被引:2,自引:0,他引:2

Oroxylin A is a flavonoid and was originally isolated from the root of Scutellaria baicalensis Georgi., one of the most important medicinal herbs in traditional Chinese medicine. The aim of this study was to investigate the ameliorating effects of oroxylin A on memory impairment using the passive avoidance test, the Y-maze test, and the Morris water maze test in mice. Drug-induced amnesia was induced by administering scopolamine (1 mg/kg, i.p.) or diazepam (1 mg/kg, i.p.). Oroxylin A (5 mg/kg) significantly reversed cognitive impairments in mice by passive avoidance and the Y-maze testing (P<.05). Oroxylin A also improved escape latencies in training trials and increased swimming times and distances within the target zone of the Morris water maze (P<.05). Moreover, the ameliorating effects of oroxylin A were antagonized by both muscimol and diazepam (0.25 mg/kg, i.p., respectively), which are GABA(A) receptor agonists. Furthermore, oroxylin A (100 microM) was found to inhibit GABA-induced inward Cl(-) current in a single cortical neuron. These results suggest that oroxylin A may be useful for the treatment of cognitive impairments induced by cholinergic dysfunction via the GABAergic nervous system. 相似文献

A brief intellectual history of the indigenization movement in Asia leads to the thesis that the generation of psychological knowledge is culture dependent. Indigenous psychologies go further and insist on viewing a target group from the natives' own standpoint. Psychological decentering underlies conceptions of human existence rooted in Asian intellectual traditions, in particular, relatedness between persons predominates in Confucianism. These conceptions demand new approaches to knowledge generation that signify a paradigmatic shift from methodological individualism to methodological relationalism. An implication is that relationships precede situations in the study of personality and social behavior. We define personality as the sum total of common attributes manifest in, and abstracted from, a person's behavior directly or indirectly observed across interpersonal relationships and situations over time. We rely on the notion that there are identifiable levels of cognition to develop a metatheoretical framework for reconstructing selfhood. Confronting the subject-object dichotomy opens the door to investigations of transcendent consciousness; confronting the self-other demarcation underlying Western theories leads to the construction of self-in-relations. 相似文献

The present study aimed to examine the therapeutic effects of Islamic intercessory prayer on warts. Forty-five participants who are mostly Muslims and infected with warts were randomized into three groups: Group-1 (uncertain, with intercessory prayer), Group-2 (uncertain, no intercessory prayer), and control group (informed, no intervention). Stress symptoms were also measured before and after prayer sessions for these three groups. The results revealed that there were no significant differences between the groups in terms of healing. Although participants believed in the therapeutic effects of prayer, when participants did not trust the intercessor, prayer had no effect on warts. 相似文献

Recent studies on attachment in middle childhood suggest that dismissing children tend to underreport their psychological distress relative to physiological indices of distress. However, this has yet to be examined in the context of behavioral indicators of distress. In this longitudinal study, a community sample of children (N?=?34, M age?=?9.59 years) completed the Child Attachment Interview at Time 1. Three years later, they returned and completed the Trier Social Stress Task for Children (TSST-C), providing ratings of their state anxiety before and after the stressor. Four raters coded children’s behavioral signs of anxiety (e.g., non-signaling gestures, eye movement, posture, facial expression) on a 7-point scale during the storytelling and arithmetic tasks in the TSST-C. Hierarchical linear regressions revealed that greater attachment dismissal was associated with greater behavioral anxiety in both the story and math tasks, but was not associated with greater increases in self-reported anxiety. Dismissal prospectively predicted increased divergence of behavioral and self-reported anxiety, such that higher dismissal was associated with higher divergence scores (i.e., underreporting of anxiety relative to behavioral indicators). We discuss these results in terms of their contribution to understanding attachment and emotion in an understudied developmental phase. 相似文献

Three studies demonstrated that interactional justice was able to attenuate egocentric bias, i.e., the tendency to regard a larger share for oneself as fair. Study 1, an experimental study of negotiation, showed that fair interpersonal treatment led to a smaller egocentric bias, quicker settlements, and fewer stalemates. Study 2 showed that fair treatment was related to a smaller egocentric bias in a real-life context. University students were more willing to accept a higher tuition fee and less willing to cut the salary of their teachers if the interpersonal treatment received from the teachers was more positive. Study 3 showed experimentally that in support of fairness heuristic theory, when the fair interpersonal treatment received could be attributed externally, its attenuating effect on the egocentric bias disappeared. 相似文献

The objective of these two experiments was to determine the role of thermal cues in material discrimination and localization, using materials that spanned a range of thermal properties. In the first experiment, the subjects were required to select the cooler of two materials presented to the index fingers. In the second, the finger that was in contact with a material that was different from that presented to the other two fingers on the same hand had to be identified. The results indicated that the subjects were able to discriminate between materials, using thermal cues, when the differences in their thermal properties were large. The changes in skin temperature when the fingers were touching the materials were, however, smaller than those predicted by the theoretical model. The ability to localize the thermal changes when three fingers on the same hand were stimulated was poor and depended on both the thermal properties of the target and the distractor materials. 相似文献

Use of the mathematical principle of inversion in young children 总被引:2,自引:0,他引:2
An important issue in the development of mathematical cognition is the extent to which children use and understand fundamental mathematical concepts. We examined whether young children successfully use the principle of inversion and, if so, whether they do so based on qualitative identity, length, or quantity. Twenty-four preschool children and 24 children in Grade 1 were presented with three-term inversion problems (e.g., 3+2-2) and standard problems of similar magnitude (e.g., 2+4-3). Problems were presented in three conditions to determine whether children used inversion at all and, if so, whether their decisions were based on quantitative or nonquantitative features of the problems. Both preschool and Grade 1 children showed evidence of using inversion in a fully quantitative manner, indicating that this principle is available in some form prior to extensive formal instruction in arithmetic. 相似文献

Suicide was the second leading cause of death for 14-17 years olds in 2002. Prior studies indicate that suicidal behaviors are especially common among juvenile delinquents, yet this association has not been examined in a national sample. The 2003 Youth Risk Behavior Surveillance System was used to examine associations between suicidal behaviors and delinquency in a nationally representative sample of 14-17 year olds. Results indicated that delinquent adolescents were more likely to have seriously considered suicide (adjusted odds ratio [AOR] = 5.44), made a suicide plan (AOR = 4.90), attempted suicide (AOR = 10.08), and required medical treatment after attempting suicide (AOR = 14.61) compared to their nondelinquent counterparts. Delinquency was significantly related to suicidal behaviors for boys and girls, but the magnitudes of effects were larger for girls. This finding suggests that delinquent youth, particularly delinquent girls, should be targeted in interventions to reduce suicidal behaviors. 相似文献

A retrospective cohort of discharged patients from all public psychiatric hospitals in Hong Kong (1997-1999) was linked to suicide data from Coroner's court. Patients hospitalized shorter than 15 days had significantly lower suicide rates than longer stay patients. The results were fairly consistent across immediate/late post discharge periods, gender, age, diagnoses, and narrow/wide definitions of suicide. This finding was opposite of what has been reported in the literature. Short hospitalization carried different suicide risks in different service settings. 相似文献
