The purpose of current investigation was identified to the effects of swallowing training with surface electromyography biofeedback on swallowing function and dietary level, satisfaction in acute stroke patients with dysphagia. Sixteen acute stroke patients with dysphagia was participated in our study. All stroke paitents were allocated in randomly to experiemental group(n=8) and control group(n=8). Both group received traditional dysphagia therapy during 30min/day, five per week, for four weeks. experimental group was perfomed swallowing training with surface electromyography biofeedback, additionally 30 min/day, and control group received only swallowing training, additionally 30 min/day. Assessments evaluated Functional Dysphagia Scale(FDS) and Penetration-Aspiration Scale(PAS) for measure of swallowing function, and Functional Oral Intake Scale(FOIS) assessed for measure of dietary level. satisfaction assessed by using Visual Analog Satisfaction Scale(VASS). In results, after intervention both group improved significant on swallowing function, and dietary level, compared to before intervention(p<0.05). After intervention, satisfaction of both group was not significant difference(p>0.05). In comparison of change score between two group, experimental group improved significantly than control group in dietary level(p<0.05). Swallowing training with surface electromyography biofeedback may be a effective dysphagia therapy to improve on dietary level in acute stroke patients with dysphagia.

Objective : This study aimed to confirm the possibility of the clinical application of oral motor facilitation technique (OMFT) protocol and neuromuscular electrical stimulation (NMES) in patients with Wallenberg syndrome. Methods : One patient with Wallenberg syndrome was treated with OMFT and NMES applied 40 times each, 5 days a week, twice a day for 4 weeks. The Comprehensive Oral-Facial Function Scale (COFFS), Korean-Mann Swallowing Ability Assessment (K-MASA), and Penetration-Aspiration Scale (PAS) were used to compare the changes before and after the intervention. Data analysis was used to compare the score changes before and after the intervention. Results : Orofacial function and swallowing ability improved after the intervention in the individual who participated in this study. Among oral motor functions, relatively greater functional improvement was observed in tongue movement compared to other functions, which was evaluated to the extent that pharyngeal swallowing was possible. Conclusions : Early swallowing rehabilitation using systematic OMFT and NMES of exercise intensity confirmed the possibility of improving oral motor function and dysphagia. In the future, complementary studies on the effects of interventions applying the OMFT and NMES will be needed.

To investigate the maturational and development competece of porcine oocytes of different diameter groups, oocytes were obtained by aspiration from slaughterdhouse ovaries. After washing three times in NCSU23 medium, each cumulus-oocyte complex was transferred into a $8{mu}ell$ drop of the maturation medium (one oocyte per drop) under paraffin oil. The diameter without zona pellucida of oocytes was measured with micor-calibrator (Mikrometer, E. Leitz) on a screen connected to a VCR on an inverted microscope $(200\times)$. After being measured, the oocytes were divided into 6 groups according to their diameter size : <105, 105 to < 110, 110 to < 115, 115 to < 120, 120 to < 125 and > $125{\mu}{\textrm}{m}$, and in vitro maturation (IVM), fertillzation (IVF) and production (IVP) of oocytes / embryo was performed. The rates of in vitro maturation on oocytes in the greater 105 ${\mu}{\textrm}{m}$ size groups(91.8~100%) were significantly (P<0.05) higher than in the < 105 ${\mu}{\textrm}{m}$ group(66.7%). The rates of sperm penetration were significantly (P<0.05) low in < $105{\mu}{\textrm}{m}$ group (50.0%) than others groups (81.6~85.5%). But the plyspermic fertilization rate was significantly (P<0.05) higher in < $110{\mu}{\textrm}{m}$ oocytes groups than in the $110\leq{\mu}{\textrm}{m}$ size groups. The rates of cleavage and development to blastocysts rose as oocytes diameter increased, however, while oocytes over $120{\mu}{\textrm}{m}$ in diameter failed to develop to blastocysts. There results suggest that porcine oocytes have acquired full meiotic competece at a diameter of $105{\mu}{\textrm}{m}$ but not yet attended full development competence to blastocyst and that oocytes have acquired full development competence at a diameter of $110{\mu}{\textrm}{m}$.
