OBJECTIVES: This study compares the emotional reaction and inhibitory effect on smoking urge between foreign antismoking advertisements and Korean antismoking advertisements. METHODS: Twenty-seven male smokers responded to a self-report survey including a Questionnaire on Smoking Urge and on emotional reactions such as disgust, anger and fear after watching a foreign antismoking advertisement, neutral images, and a Korean antismoking advertisement. We compared the smoking urge between the foreign antismoking advertisement and Korean antismoking advertisement and investigated emotional reactions associated with reduction in the smoking urge. RESULTS: The foreign antismoking advertisement inhibited the smoking urge but Korean antismoking advertisement did not. A significantly higher emotional response was evoked by the antismoking advertisements than in neutral images. However, among the emotions respondents reported about the foreign antismoking advertisement, only disgust was significantly associated with smoking urge. CONCLUSION: These results support published research, in that warning labels with high-rated emotional reactions are associated with reduction in the smoking urge. High emotional reactions such as disgust may enhance the effect of Korean antismoking advertisements.

Objective: : Electrooculography (EOG) records eyeball movements as changes in the potential difference between the negatively charged retina and the positively charged cornea. We aimed to investigate whether reliable EOG waveforms can be evoked by electrical stimulation of the oculomotor and abducens nerves during skull base surgery. Methods: : We retrospectively reviewed the records of 18 patients who had undergone a skull base tumor surgery using EOG (11 craniotomies and seven endonasal endoscopic surgeries). Stimulation was performed at 5 Hz with a stimulus duration of 200 μs and an intensity of 0.1–5 mA using a concentric bipolar probe. Recording electrodes were placed on the upper (active) and lower (reference) eyelids, and on the outer corners of both eyes; the active electrode was placed on the contralateral side. Results: : Reproducibly triggered EOG waveforms were observed in all cases. Electrical stimulation of cranial nerves (CNs) III and VI elicited positive waveforms and negative waveforms, respectively, in the horizontal recording. The median latencies were 3.1 and 0.5 ms for craniotomies and endonasal endoscopic surgeries, respectively (p=0.007). Additionally, the median amplitudes were 33.7 and 46.4 μV for craniotomies and endonasal endoscopic surgeries, respectively (p=0.40). Conclusion : This study showed reliably triggered EOG waveforms with stimulation of CNs III and VI during skull base surgery. The latency was different according to the point of stimulation and thus predictable. As EOG is noninvasive and relatively easy to perform, it can be used to identify the ocular motor nerves during surgeries as an alternative of electromyography.
