최근 동물과 인간의 뇌에서 Opiate 수용체들이 발견이 되고 체내에서 생산된 내인성 Opioid Peptides의 발견으로 이들 Peptides와 정신병 특히 정신분열증과 어떤 관계가 있지않나 하고 이 방면에 대한 연구가 활발하게 진행되고 있다. 이에 본 저자는 내인성 Opioid Peptides와 정신병 특히 정신분열증과의 관계에 대한 지금까지의 연구결과들을 전반적으로 정리하여 알아보고져 한다. Recent discovery of opiate receptors in animal and human brains and identification of endogenously produced opioid peptides have led to many studies about effects and relatedness of endogenous opioid peptides in psychoses, especially schizophrenia. In spite of enthusiastical studies about this field, the results are yet contradictory. The results of the studies can be grouped into two categories: One category is that in which no relation could be identified between the peptides and psychoses. The other category that showed some correlation could furhter be divided into two groups. The first one is that the schizophrenic symptoms may be related with increased level or overactivity of endogenous opioid peptides in human central nervous system, and the other one is that the schizophrenic symptoms may be related with lowered level or deficient activity of endogenous opioid peptides in human central nervous system. The author attempted to overview the anatomical distribution, pharmacological actions of endogenous opioid peptides, and the results of recent studies showing some relatedness between endogenous opioid peptides and psychoses, especially schizophrenia.

To clarify the spatial distribution pattern of macrozoobenthos in Korean coastal waters in the summer season and investigate the relationship between community structure and benthic environmental factors, field surveys on community structure and benthic environmental factors were conducted at 117 stations in August 2017. A total of 613 macrobenthic species were identified, with the mean density of 1,228 ind./m<sup>2</sup> and the mean biomass (wet weight) of 110.9 g WW/m<sup>2</sup>. Rich biodiversity was found at stations near Wando and along the coast of the East Sea, and there is a trend that stations with greater biodiversity also showed higher mean density as well. The dominant species in all the coastal areas in Korea was Heteromastus filiformis, which were found at most of the stations during the survey. The relatively deep areas in the East Sea were dominated by Magelona johnsoni and Maldane cristata, which were the third and ninth dominant species in the study areas, respectively. Pseudopolydora kempi and Rhynchospio sp. were observed only at the station located in the Nakdong River estuary. From the cluster analysis the stations could be clustered into three station groups with more similar faunal composition. Group A was located in the eastern coast, characterized with deep water depth and low levels of sand contents, while Group B was located in the southern coast, characterized by shallow depth of water and high content of mud and organic matter. Lastly, Group C was in the western coast, demonstrating low levels of mud content and organic matters. The biodiversity of macrobenthic species in the study area showed high positive correlation coefficients with benthic environmental factors such as sorting, clay, silt, and contents of organic matter in sediments, but negatively correlated with the sand contents. Major dominant species, Theora lata and Eriopisella sechellensis, both showed negative correlation coefficients with the sand contents, but a relatively high positive correlation with the levels of organic contents.It can be concluded that the spatial distribution patterns of macrobenthic organisms in Korean coastal waters are affected by depth, sediment type, and contents of organic matters.
