  • Objective : The aim of this study was to assess protective effects of Whangryonhaedoktang on the chronic mild stress (CMS) animal model of depression. Method : Male Sprague-Dawley rats were used for this study. The subjects were divided into 3 groups (CMS-drug group: Whangryonhaedoktang was administered during CMS procedure, CMS-vehicle: water was administered during CMS procedure, normal control group: without CMS procedure). After 4 weeks of CMS procedure, Morris water maze (MWM) test and open field test were executed and tyrosine hydroxylase (TH) was measured in ventral tegmental area (VTA) and locus coeruleus (LC) of rat brain. Result : 1. CMS procedure induced defects of spatial learning in early period of MWM test. 2. CMS Whangryonhaedoktang group showed shorter escape latency in comparison with CMS control group in MWM test on the first day of the test. 3. CMS Whangryonhaedoktang group and CMS control group showed no significant difference of activities and emotional behaviors in comparison with normal control group in open field test. 4. CMS Whangryonhaedoktang group showed significant inhibition effects of TH expression in VTA and LC areas in comparison with CMS control group. Conclusion : These results suggest that Whangryonhaedoktang may have inhibition effects to early period defects of spatial learning and protective antidepressant effects in CMS model rats.

  • Objectives This study was performed to investigate the effects of Saengkanggamchotang (SKT) on the monosodium iodoacetate (MIA) induced osteoarthritis in rats. Methods Osteoarthritis was induced by injection of MIA (50 ul, 60 mg/ml) into knee joints of rats. Rats are divided into a total of 4 groups (normal, control, positive comparison group, SKT treated group, each n=6). Normal group are not treated at all without inducing osteoarthritis whereas control group were induced for osteoarthritis by MIA and oral medicated with 20 ml of distilled water per day. Positive comparison group was injected with MIA and after 7 days, that was taken indomethacin (30 mg/kg/mouse). SKT treated group was injected with MIA and after 7 days that was taken SKT (30 mg/kg/mouse). Positive comparison group and SKT treated group were oral medicated for each substance a total of 4 weeks with one time per day. After experiments (from 1 week after injection of papain to 4 weeks elapsed), the functions of liver and kidney, Prostaglandin E2, inflammatory cytokine (IL-$1{\beta}$, IL-6, TNF-${\alpha}$), osteocalcin, TIMP-1, MMP-9 within serum. Knee joint structures were observed by H&E, safranin-O staining method, and amount of cartilage were measured by ${\mu}CT$-arthrography. Results 1) Hind paw weight bearing ability was significantly improved. 2) Functions of liver and kidney were not affected. 3) Prostaglandin E2, osteocalcin, TIMP-1, MMP-9 in serum were significantly decreased. 4) Inflammatory cytokine IL-$1{\beta}$ was significantly decreased, and IL-6, TNF-${\alpha}$ were decreased but had not significant. 5) In terms of histopathology, significantly reduced subsidence of cartilage and bone in H&E staining. And in Safranin O staining, proteoglycan content in synovial membrane was significantly increased compared with control group. 6) Destruction of cartilage on ${\mu}CT$-arthrography was significantly reduced. Conclusions Based on all results mentioned above, Saengkanggamchotang (SKT) is believed to be meaningful for suppressing the progress of osteoarthritis and its treatments.

  • This study evaluated the Comparison of the Effectiveness of Pelvic Floor Muscle exercise and Biofeedback treatment for Genuine Stress Incontinence I assigned 60 participants to 2 groups : 30 to the pelvic floor muscle exercise group and 30 to the biofeedback group. Treatment protocol lasted for 6 weeks. Peak pressure, and duration time of pelvic muscle contraction were evaluated by a perineometer. Lower urinary symptoms, sexual matter and life style scores were achieved by using Jackson's scale. The treatment efficacy of the pelvic floor muscle exercise is compared with the biofeedback group and the main results of the comparison are as follows : 1. Pelvic muscle contraction 1) The peak pressure in the biofeedback group was significantly increased(P=0.000). 2. The frequency and quantity of incontinence 1) The frequency of incontinence in the biofeedback group was significantly decreased(P=0.000). 2) The quantity of incontinence in the biofeedback group was significantly decreased(P=0.000). 3. The lower urinary symptoms Daily frequency(P=0.000), nocturia(P=0.000), urgency(P=0.000), bladder pain(P=0.000), unexplained incontinence(P=0.048), wearing protection(P=0.022), changing outer clothing(P=0.005), hesitancy(P=0.008), intermittent stream(P=0.000), abnormal strength of stream(P=0.004), retention(P=0.000), incomplete emptying(P=0.000), and inability to stop mid stream(P=0.006) of the lower urinary symptoms in the biofeedbatk group were significantly decreased. 4. The sexual matters The dry vagina (P=0.004) and pain during sexual Intercourse (P=0.002) in the biofeedback group was significantly decreased. 5. The life style The fluid intake restriction(P=0.007), affected daily task(P=0.003), avoidance of places & situation(P=0.003), interference in Physical activity (P=0.002), interference in relationship with other people(P=0.01), and feeling about the rest of life with urinary symptom(P=0.000) in the biofeedback group were significantly decreased.

  • Objective: The purpose of this study was to investigate the effect of foot strengthening exercise program and functional insoles on joint angle and plantar pressure in elderly women. Thirteen elderly women who were enrolled in a university senior citizens academy of a metropolitan city in 2017 were divided into two groups: exercise group with functional insole (n=7) and exercise group without functional insole (n=6). Method: Three-dimensional motion analysis and Pedar-X were performed to compute the joint angle and the foot plantar pressure, respectively. Two-way repeated measure ANOVA was conducted to compare dependent variables within and between groups. The significance level was set at ${\alpha}=.05$. Results: The range of motion (ROM) of the ankle, knee, and hip joints in the exercise group with functional insole increased significantly more than the exercise group without functional insole. In both the experimental group and the comparison group, the maximum foot plantar pressure and the mean foot plantar pressure were decreased, but the comparison group without functional insole showed more decrease. Since the experimental group demonstrated greater pressure than the comparison group in the contact area (forefoot, midfoot), it was distributed over a greater area. Conclusion: The results of this study suggest that participation in foot strengthening exercises and using a functional insole has more positive effects than foot strengthening exercises alone on the joint angle and plantar pressure in elderly women. Increased foot plantar pressure led to an increased contact area (forefoot, midfoot) for distribution of the foot plantar pressure, but the effect of reducing the maximum and average plantar pressures was incomplete. However, wearing functional insoles along with exercise, could help in improving the stability of the joints, by increasing the range of motion, and could help the elderly in movement of the muscles more effectively, leading to an improvement in gait function.

  • To investigate the relationship between recurrent aphthous ulcer and oral mucosal keratinization, exfoliative cytology in buccal mucosa, lip mucosa, tongue mucosa were performed on 25 recurrent aphthous ulcer patients and 25 controls whose age ranged from 10 to 65. Keratinization cell ratio was then measured. The results were as follows : 1. Yellow cell ratio in the control group was more than that in the patient group in buccal mucosa, lip mucosa, tongue mucosa. Red cell ratio in the control group was more than that in the patient group in lip mucosa. Blue cell ratio in the patient group was more than that in control group in all regions( p(0.01) 2. In the comparison by sex, the patient group showed no significant difference in all site but, the control group showed different results according to the site; males were more than females in yellow cell, but less than females in red cell Females were more than males in yellow cell, but less than males in red cell. 3. In the comparison by age, patient group showed no significant difference in all site, but the control group showed significantly high yellow cell ratio in buccal and tongue mucosa over the age of 50. In conclusion, there was close relationship between recurrent aphthous ulcer and decreased oral mucosal keratinization. In other words, reduced oral mucosal keratinization must be recommended for prevention of recurrent aphthous ulcer.
