本研究选取赣南医学院197名全日制在校学生为研究对象,采用西南大学黄希庭教授编制的大学生自立量表和Paulhus于1985年编制的控制圈(Spheres of Control,SOC)量表为调查工具,对大学生自立与心理控制源的问题进行了调查研究,以期对大学生的自立和心理控制能力进行描述,并且试着探讨大学生自立和心理控制能力之间的关系。全部数据采用SPSS8.0进行录入和统计分析。
[Objective] This study aimed to establish Balb/c mice model for food allergy caused by Chinese lobsters through using intraperitoneal injection for sensitization and explore methods for in vitro identification and evaluation of food allergy caused by Chinese lobsters. [Method] The 40 male Bal/c mice were divided into ovalbumin（OVA） positive control group, Coca＇s solution negative control group, blank control group and model group. Balb/c mice model was established by intraperitoneally injection of immunized Balb/c mice with OVA or Chinese lobster crude protein with aluminum hydroxide adjuvant. IgE and histamine levels in serum after the second challenge were determined by ELISA method, and the specific IgE antibody titer was determined by passive cutaneous anaphylaxis test（PCA）; additionally, spleen index and histological changes in the small intestine, as well as food allergy symptoms after challenge were also calculated or observed. [Results] After the last challenge, IgE content was（236.75 ±73.39） μg/L in the Chinese lobster crude protein group, revealing no difference with that in the OVA group, but significantly higher than that in either the Coca＇s solution group or the blank control group（P 0.01）;histamine content in serum in the Chinese lobster crude protein group was（406.55±232.79）, significantly higher than that in the blank control group（P0.01）. In the passive cutaneous anaphylaxis test, IgE antibody titer reached 1/16 after the last challenge in the Chinese lobster crude protein group. Spleen index in both Chinese lobster crude protein group and OVA group was significantly greater than that in either the Coca＇s solution group or the blank control group（P0.01）. What＇s more, infiltration of inflammatory cells like lymphocytes and eosnophils at the lamina propria of intestinal mucosa was also observed both Chinese lobster crude protein group and OVA group. [Conclusion] This study established Balb/c mice model for food allergy caused by Chinese lobsters; serum IgE an
"心理控制源(focus of control)"来自心理学家罗特(Rotter,1966)的社会学习理论。国内外迄今关于"心理控制源"的研究多集中于对弱势群体的研究。基于当前的研究现状,我们决定以赣南医学院学生为被试者研究大学生的心理控制源,了解他们的控制能力,以丰富控制源的有关研究,也可以推动心理控制源理论在正常群体中的应用。
