Purpose: The purpose of this study was to determine the effect of a 2-week somatosensory stimulation program on cognitive function and ADL of patients with brain damage. Methods: The sample consisted of two groups of patients with stroke: 10 patients with a mean age of 59.0 years who were treated with somatosensory stimulation, and 9 patients with a mean age of 51.78 years, who were not treated with somatosensory intervention. A nonequivalent control group non-synchronized design was used to assess the functional recovery after stroke. Instruments used in this study were MMSE-K for cognitive function and FIM for ADL. Results: The hypothesis 1 that "Patients with stroke who were treated with the somatosensory stimulation program will show higher MMSE-K score than that of the non-treatment group" was supported(Z = -2.390, p = .017). The hypothesis 2 that "Patients with stroke who were treated with the somatosensory stimulation program will show higher FIM score than that of the non-treatment group", however, was partially supported(social cognition: Z = -2.204, p = .045). Conclusion: Somatosensory stimulation was effective to patients with stroke in improving their cognitive function. These findings suggest that somatosensory input can be adopted to nursing intervention for functional recovery after stroke.

Purpose: To identify the characteristics and physiological function of the nicotinic receptor expressed in human retinoblastoma cells. Methods: We measured possible nicotinic signaling in WERI-Rb-1 cells using the Ca2+ imaging technique and the patch clamp method. Results: 1) Nicotine-induced [Ca2+]i rise arose entirely through Ca2+ influx, which was completely abolished by hexamethonium (100 μM). 2) Nicotine also induced remarkable depolarization from -56.6±3.7 mV to -29.6±3.6 mV (n=4) under current clamp mode, but it failed to directly activate the T-type Ca2+ channel expressed in retinoblastoma cells. Conclusions: Nicotinic activation can increase the intracellular calcium level through calcium influx in the undifferentiated retinoblastoma cells, which may play important roles in cell proliferation, differentiation, and cell death.

Purpose: This study was intended to analyze the types and measurement parameters of non-pharmacological interventional studies for nonalcoholic fatty liver disease (NAFLD). Methods: NAFLD related literatures were systematically reviewed. The existing literatures were searched electronically using the data base of PubMed, a Medline data base of the National Library of Medicine with the key words of nonalcoholic fatty liver disease, NAFLD, nonalcoholic steatohepatitis, and NASH. The criteria for inclusion in this review were 1) non-pharmacological intervention, 2) human, 3) English. Finally, 20 articles were included in the review. Results: The major findings of this study were as follows: 1) the types of non-pharmacological intervention were exercise (35%), caloric restriction (30%), and lifestyle modification with combination both of exercise and caloric restriction (35%), 2) Almost all studies adopted various measurement parameters derived from pathophysiological mechanism-based biomarkers such as anthropometric indices, biochemical parameters,body fat mass, and liver biopsy results. Conclusion: Non-pharmacological interventions have been reported to be effective to improve NAFLD status, and many objective biomarkers confirmed supported these findings. Therefore, the development of nursing interventions for NAFLD subjects is needed and the consideration of using mechanism-based biomarkers is suggested to verify nursing outcomes objectively.

Purpose: The present study aimed to identify the characteristics and physiological function of the P2Y11 receptor, a receptor likely expressed in human retinoblastoma cells. Methods: We measured possible P2Y11 signaling in WERI-Rb-1 cells using a Ca2+ imaging technique and RT-PCR. Results: 1) 10 ?M ATP elicited a strong but transient increase in Ca2+ in the WERI-Rb-1 cells, and this Ca2+ rise was well maintained after external Ca2+-depletion. 2) ATP-induced Ca2+ response arose entirely through Ca2+ mobilization. 3) P2Y11 agonist (BzATP, 100 ?M) increased Ca2+ by 31.2±3.7 % of ATP effect. 4) mRNA for P2Y11 subtype was identified using RT-PCR. Conclusions: P2Y11 purinergic activation can increase the intracellular calcium level through calcium mobilization in undifferentiated retinoblastoma cells, which may play an important role in cell proliferation, differentiation, and even pathologic processes.
