Ocular HSV-1 shedding from latently infected rabbits was induced by iontophoresis of 0.01% epinephrine into the eye. Anodal Iontophoresis of epinephrine was performed at 0.8 mAmps for 8 min once a day for 3 consecutive days. Shedding was determined by the presence of HSV-1 in the preocular tear film obtained via eye swabs. Bilateral epinephrine(More)
The purpose of this study was to investigate the influence of the hedonic properties of odors and the attention of subjects on components of the olfactory event-related potentials (OERP). The subjects were seven healthy male students. Two odors (orange and eugenol) of different hedonic properties were presented to the subjects via a constant-flow(More)
The development of an animal model for herpes simplex virus (HSV) reactivation is of great importance in studying HSV latency, reactivation, recurrence, and chemotherapy. Epinephrine iontophoresis to the cornea can induce HSV type 1 (HSV-1) ocular shedding from latently infected rabbits. In the present experiment, adrenergic induction of HSV-1 was enhanced(More)
Iontophoresis of 0.01% levo(-) epinephrine for 8 min at 0.8 mAmp once daily for 3 consecutive days induces ocular shedding of herpes simplex virus type 1 (HSV-1) in latently infected rabbits. In the present experiment, we tested dextro(+) and levo(-) epinephrine for their comparative effects on induced HSV-1 ocular shedding. One hundred percent of the eyes(More)
Surface electromyogram (EMG), blood pressure (BP), blink rate (BR) and heart rate (HR) were recorded before and during 4 types of mental task. The mental task involved 3 tasks that encompassed the memory (M), visual search (VS) and color-word (CW) tasks besides the control task (CT) of maintaining a similar posture while focusing on a single spot on the(More)
PURPOSE The involvement of the epithelial mesenchymal transition (EMT) in the process of corneal wound healing remains largely unclear. The purpose of the present study was to gain insight into Slug expression and corneal wound healing. METHODS Slug expression during wound healing in the murine cornea was evaluated using fluorescence staining in vivo.(More)
Timolol iontophoresis into the eye can induce herpes simplex virus type 1 (HSV-1) shedding in rabbits latently infected with HSV-1 strain McKrae. Anodal iontophoresis of 0.01% timolol was done at 0.8 mAmp for 8 min once a day for 3 consecutive days. Viral shedding was determined by the presence of HSV-1 in the preocular tear film obtained by eye swabs. In(More)
The present studies were undertaken to examine the hypothesis that sucrose feeding at weaning may alter the preference for sucrose in the adolescence. Chronological changes of hypothalamic dopamine (DA), its metabolite, 3,4-dihydroxy-phenylacetic acid (DOPAC) and norepinephrine (NE) contents were also measured by HPLC. In 21 day-aged rats, 10% sucrose or(More)
We studied the distributions of four different cyclic AMP-specific phosphodiesterase isoform mRNAs (APDE1-4) and compared them with that of 63 kDa calmodulin-stimulated phosphodiesterase (CPDE) in the rat brain by in situ hybridization histochemistry using specific radiolabeled oligonucleotides. The distribution patterns were unique for all the APDE(More)
We determined the effect on feeding of Lys-D-Pro-Thr (LDPT), an interleukin-1 beta 193-195 analogue which antagonizes the analgesic effects of interleukin-1 beta. Intracerebroventricular administration of 2 micrograms/rat LDPT increased food consumption at the 0-1 h time period, although food intake was reduced by LDPT at the 1-2 h time period. There was no(More)
