Scavenger receptors (SRs) are transmembrane cell surface molecules recognized in apophotic cells, bacteria and lipopolysaccharide. With no physiological information on SRs in insects except SR-CI of Drosophila melanogaster, a putative SR gene was cloned and characterized in Spodoptera exigua. A partial S. exigua SR gene was obtained from hemocyte transcripts and exhibited high homology with type C. Its expression was confirmed in all developmental stages. Among different tissues, S. exigua SR was expressed highly in hemocytes. To confirm change in SR expression by infection, Escherichia coli was injected to fifth instar and RNA was extracted after 10 hours. SR expression in hemocytes of E. coli injected larva was not significantly different from the control but SR expression in fat body of E. coli injected larva was higher than the control. It is expected that SRs of S. exigua are related with immune responses against bacteria such as E. coli. To address its function, S. exigua SR expression was suppressed by double-stranded RNA (dsRNA).

Purpose: The purpose of this study was to investigate the influence of body perception image training on functional recovery of upper limb in stroke patients, not image training with visual stimulation for specific task. Methods: Thirty inpatients(15males, 15females) who were diagnosed as stroke participated with agreement in this study, also they were divided randomly by experimental and control groups. Before traditional therapeutic exercise, body perception image training was performed in experimental group, as well as control group took a rest, respectively. Body perception image training program was modified using body scan part of Mindfulness Based on Stress Reduction(MBSR) for present study, then it was spplied individually for 4weeks, 5days a week for 10 min. To determine the effects of this training program, data of muscle activities were collected and analyzed from biceps brachii, upper trapezius and deltoid muscles through electromyogram(EMG). Results: By comparison of changes in muscle activities, both experimental and control groups showed significant increase of muscle activities from all theree of muscles after therapeutic intervention(p<.001). In particular, increment of upper trapezius muscle activity in experimental group was markedly higher than control group(p<.05). Conclusion: These results may indicate that traditional therapeutic exercise combined with body perception image training result in increase of muscle activity of upper limb, suggesting it is beneficial for functional recovery in stroke patients.
