  • Endoplasmic reticulum (ER) stress is mediated by disturbance of $Ca^{2+}$ homeostasis. The store-operated calcium (SOC) channel is the primary $Ca^{2+}$ channel in non-excitable cells, but its participation in agent-induced ER stress is not clear. In this study, the effects of tunicamycin on $Ca^{2+}$ influx in human umbilical vein endothelial cells (HUVECs) were observed with the fluorescent probe Fluo-4 AM. The effect of tunicamycin on the expression of the unfolded protein response (UPR)-related proteins BiP and CHOP was assayed by western blotting with or without inhibition of Orai1. Tunicamycin induced endothelial dysfunction by activating ER stress. Orai1 expression and the influx of extracellular $Ca^{2+}$ in HUVECs were both upregulated during ER stress. The SOC channel inhibitor SKF96365 reversed tunicamycin-induced endothelial cell dysfunction by inhibiting ER stress. Regulation of tunicamycin-induced ER stress by Orai1 indicates that modification of Orai1 activity may have therapeutic value for conditions with ER stress-induced endothelial dysfunction.

  • Purpose: The purpose of this study was to identify clinical nurses' knowledge of pharmacology, their need on pharmacology education contents, and perceived connectivity between knowledge and clinical practice. Methods: Subjects consisted of 114 clinical nurses. They responded to self-administered questionnaires about knowledge of pharmacology and need in pharmacology, and perceived connectivity between the knowledge and clinical practice. Results: The mean score of knowledge of pharmacology was $5.2{\pm}1.7$. The mean score of need on pharmacology in clinical practice was $7.9{\pm}1.9$, and those of satisfaction, application, and confidence with clinical performance by applying the knowledge to clinical practice were $7.4{\pm}1.9$, $6.8{\pm}2.0$, and $7.5{\pm}2.1$ respectively. Knowledge of pharmacology was positively correlated with perceived connectivity between knowledge and clinical practice. Scores of need of dose calculations was the highest among 14 units of pharmacology education contents in undergraduate courses while that of development of new drugs was the lowest. Scores of need of coagulation modifier drugs and thrombolytic agents were the highest among 16 units of pharmacology education contents by system specific drug while those of dermatologic and ophthalmic drugs were the lowest. Conclusion: The results indicate that knowledge of pharmacology is important in promoting perceived connectivity with clinical practice by applying knowledge to clinical practice.

  • Mandatory registration of clinical trials in public registry can ensure the transparency of clinical trials. Public clinical trial registry of can provide current chronological and geographical distribution of clinical trial throughout the country. We used public clinical trial registry provided by Ministry of Food and Drug Safety to analyze current status of clinical trial from 2014 to 2016 in South Korea. The number of clinical trials in antineoplastic and immunomodulating agents area was the greatest, followed by cardiovascular system and antiinfectives for systemic use as a whole. From 2014 to 2016, overall number of clinical trials decreased while the number of phase I clinical trials increased. Seoul accounted for more than half number of clinical trials in Korea. Supports for clinical trials in non-metropolitan area needs to be considered.
