Many recent studies have suggested that deficits in dietary-based omega-3 poly unsaturated fatty acids may make an etiological contribution to mood disorders and that supplementation with omega-3 poly unsaturated fatty acids may provide a treatment strategy (Hagg, 2003; Parker, Gibson, Brotchie, Rees, & Handzi-Pavlovic, 2006; Vaddadi, 2006). However, a few studies did examine the relationship between daily food intake and mood disorders. Thus, we surveyed students with regard to these relationships. Two hundred and forty eight university students completed the SDS and eighty item food appetite survey. Results showed that low-depression group tended to favor fish and deep yellow vegetables more than the high-depression group. These results suggest that a preference for fish and deep yellow vegetables relates to depression. Antioxidative effects of these foodstuffs may facilitate antidepressive effects of omega-3 poly unsaturated fatty acids.

The purpose of the present study was to explore the frequency of pain in dreams. Three hundred and fifty-four undergraduates, ranging in age from 19 to 32 years, were surveyed using a 13-item questionnaire that asked about the frequency of pain in dreams and a 26-item questionnaire on the frequency of dream recall (Okada, 2000, 2001). Factor analysis of the pain experience indicated that pain in dreams fell into two categories - feeling pain congruent with one's state and not feeling pain congruent with one's state. Feeling pain correlated with the frequency of smell, taste, and touch in dreams, but not feeling pain did not.

This study aims to develop an abridged version of the Auditory Hallucination and Mishearing Questionnaire (SORAMIMI Questionnaire). The abridged version is designed to be used as a quick tool for the assessment of auditory hallucination, mishearing, and subjective hearing loss. Data from 469 university students were used to analyze the item statistics and psychometric properties. Twenty-four items with an optimal combination of high item-total correlations and reliability in assessing changes were selected for the SORAMIMI Questionnaire.

Readers may have various experiences while reading a narrative, such as imagining the world described in the narrative, empathizing with the protagonist, and thinking about the author of the narrative or the real world. Referred to as "reader response" in literary theory, these experiences are important topics in the study of a reader's interactions with a literary text. To investigate differences among individuals in the degree of openness to these experiences during narrative comprehension, we translated the Literary Response Questionnaire (LRQ) developed by Miall and Kuiken (1995) and selected 37 items from the original scale to develop a Japanese version (LRQ-J). This survey was administered to 497 undergraduate students. The results showed that all subscales of the LRQ-J had internal consistency. Respondents' scores showed significant correlations with fantasy proneness, imaginative involvement, imagery vividness, and ego-resiliency. The results suggest that the LRQ-J has sufficient reliability and validity. The psychological characteristics of experiences assessed by the LRQ-J are discussed.

長期間保存されたNPVについて、その病原性を確認するためにハスモンヨトウ幼虫により生物検定を行った。多角体を水に浮遊して4℃の条件下で24年から34年間保存した7種類のNPVウイルス株を供試した。この結果、6種類のウイルス株が病原性を保持していることが確認された。病原性が確認された各ウイルス株のLC50値(PIB/ml)は、ハスモンヨトウNPV福山株は5.5-6.1×10(5)、ワタヨトウNPVエジプト株は6.1-8.6×10(5)、ヨトウガNPV芸北株は1.5-2.0×10(9)、ヨトウガNPV東京株は1.9-4.3×10(8)、シロモンヤガNPVは3.9-4.7×10(8)、アワヨトウNPVは3.6-5.7×10(7)で、24年から28年間の長期保存の間に病原力は低下したが、病原性が残存していることが明らかになった。一方、保存期間が34年であったクサシロキヨトウNPVでは病原性が消失していた。また、長期間の保存によって病原力が低下した場合でも、再接種を行い虫体によりウイルスを増殖させることによって病原力が回復することが確認された。
