The present study was undertaken to analyze the effects of different types of treatment on excess post exercise oxygen consumption (EPOC), flexibility, free radical and antioxidants in women using a horseback riding therapeutic device. Subjects were trained in regular horseback riding exercises for 12 weeks (3 times/wk). The effects of this exercise were examined by means of a single session of horseback riding that lasted for 30 min. 21 women were recruited from a public health center and divided into 3 groups (passive recovery group, passive+massage recovery group, and dynamic recovery group). 3 types of recovery patterns were determined after a single trial of horseback riding exercise. Their flexibility were determined pre-and post-training by Paired T test, and ANOVA were used to analyze the data. The results were as follows: Among the 3 groups, the dynamic recovery group showed the highest levels of EPOC compared to the other groups, and also showed higher levels of anti-oxidants, as did the passive+massage recovery group compared to the passive recovery group. Moreover, horseback riding exercise greatly increased flexibility in the women. In conclusion, regular horseback riding training is recommended to enhance the flexibility of women and dynamic recovery is recommended to enhance EPOC and anti-oxidants after a single bout of exercise. Further study is needed in this area.

This study aimed to evaluate several biological activities of Pharbitis nil and to isolate an anticancer agent from its methanol extract. Pharbitis nil seeds were extracted with methanol (PNM). Then, PNM was fractionated into solvent layers such as ethyl acetate fraction (PNE), butanol fraction (PNB), and water fraction (PNW). The biological activities of the fractions were analyzed for tyrosinase inhibition, lipase inhibition, DPPH-free radical scavenging, and cell growth inhibition. PNM showed strong growth inhibition of prostate cancer PC-3 cells. PNM was subjected to Diaion HP-20 and eluted stepwise with 50%, 80%, and 100% methanol. Then, for activity-guided fraction, each fraction was analyzed for growth inhibition of prostate cancer PC-3 cells by using an MTT assay. Because the 100% fraction showed significantly strong inhibitory activity, the fraction was further separated in the reverse phase C18, which was eluted with 80% and 90% methanol. The 90% fraction was further subjected to Sephadex LH-20 using a mobile solvent of 100% methanol. Finally, the compound PN was partially purified for HPLC analysis. PN showed cell growth inhibitory activity and induced the apoptosis and cell cycle arrest of prostate cancer PC-3 cells, as measured by flow cytometry. The results together suggest that Pharbitis nil possesses various biological activities, especially the inhibitory activity for the proliferation of prostate cancer PC-3 cells, suggesting the possibility of its use as an anticancer agent.
We introduced the physiological responses of aging, active aging and also suggest the impact of physical exercise on body health status and elderly immunity. In this purpose, we searched the Pub Med data base for the articles (include our experimental papers) and review papers having the terms 'Aging', 'Active aging' and 'Physical activity and elderly' in the title, published from 1999 until 2018. The results were as follows: Exercise training has been extensively studied about the reduction of inflammation, oxidative stress, disease, and aging in syndrome X patients and elderly. Combined and aerobic or resistance exercise training could reduce obesity, insulin resistance, type 2 diabetes and hypertension. Exercise training has been extensively studied in cancer settings as part of prevention or treatment strategies. From this research, regular exercise has the potential to target tumor growth through regulation of inflammation and immune responses such as lactate clearance, NK cell activation (innate immunity), activation of cytotoxic immune cells, T cell activation (adaptive immunity), and immune surveillance. However, Endurance physical activity not only induces thermogenesis and diverse sports injuries but also elicits mobilization and functional enhancement of monocytes, neutrophils (which is caused by the cytokine changes such as TNF-alpha, IL-1) whereas it suppresses cell mediated immunity causing to increased susceptibility to inflammation and infections like cough and URTIs (upper respiratory track infections) in young and especially in elderly people. Therefore, Strategies to prevent physical fatigue, sports injuries include avoid overtraining, Adequate recovery and various type of rest during and after physical activity and assuring adequate nutrition supplementation such as glutamine, vitamin B, vitamin C, carbohydrate, ion or berry-contain sports beverages is helpful in physically active elderly.

This study was aimed to evaluate the masticatory efficiency after botulinum toxin type A (BTX-A) injection during 12 weeks using objective and subjective test. Also, we compared the difference of masticatory efficiency between group that injected into the masseter muscle only (M-group) and group that injected into the masseter and temporalis muscle (M-T group). The mixing ability index (MAI) was used as the objective indicator, and visual analogue scale (VAS) and food intake ability (FIA) index were used as the subjective indicators. It was concluded that masticatory efficiency was significantly lowered after a BTX-A injection into the masticatory muscle, but it gradually recovered in a predictable pattern by the 12 weeks. The disturbance of subjective masticatory efficiency was lasted longer than objective masticatory efficiency. The masticatory efficiency was lower in M-T group than M group. It was statistically significant in the VAS and FIA at 4 weeks, but the MAI showed no significancy. After 4weeks, there was rapid recovery of muscle function in M-T group, and the difference between two groups was not significant. It could be concluded that there will be no serious disturbance of mastication compared to injection is done only into the masseter muscle, even if injection is done into the masseter and temporalis muscle in dose of this study. According to the food properties, it was confirmed that people feel more discomfort on taking hard and tough foods after BTX-A injection and not only hard foods, but also intake of soft and runny foods were influenced by botulinum toxin injection.

State of problem: Cement-retained implant-supported prostheses are routinely used in dentistry. The use of high strength cements has become more popular with the increasing confidence in the stability of the implant-abutment screw connection and the high survival rates of osseointegrated implants. No clinical data on retention of metal copings using CAD/CAM. To evaluate retention of metal copings using CAD/CAM system bonded to short titanium abutment with four different cements and compare retentive strength of metal copings with sandblasting or without sandblasting before cementation. Forty titanium abutment blocks were fabricated and divided into 4 groups of 10 samples each. Forty metal copings with occlusal hole to allow for retention testing were fabricated using CAD/CAM technology. The four cements were Fujicem(Fuji, Japan), Maxcem Elite(Kerr, USA), Panavia F2.0(Kurarary, Japan) and Superbond C&B(Sunmedical, Japan). The copings were cemented on the titanium abutment according to manufacture's recommendation. All samples were stored for 24h at 37oC in 100% humidity and tested for retention using universal testing machine(Instron) at a crosshead speed of 1.0mm/min. Force at retentive failure was recorded in Newton. The mode of failure was also recorded. Means and standard deviations of loads at failure were analyzed using ANOVA and Paired t-test. Statistical significance was set at P<0.05. Panavia F2.0 provided significantly higher retentive strength than Fujicem, Maxcem Elite(P<0.05). Sandblasting significantly increased bond strength(P<0.05). The mode of failure was cement remaining principally on metal copings. Within the limitation of this study, Panavia F2.0 showed significantly stronger retentive strength than Fujicem, Maxcem Elite(p<0.05). The Ranking order of the cements to retain the copings was Panavia F2.0, Fujicem = Maxcem Elite. Sandblasting significantly increased bond strength(P<0.05). The retentive strength of metal copings on implant abutment were influenced by surface roughness and type of cements.
Obstructive sleep apnea syndrome(OSAS) in childhood is unique and different n-om that in adulthood in several aspects, including pathophysiology, clinical features, diagnostic criteria, complications, management, and prognosis. Characteristic features of childhood OSAS in comparison with the adult form are the variety of severe complications such as developmental delay, more prominent behavioral and cognitive impairments, vivid cardiovascular symptoms, and increased death risk, warranting a special attention to the possible diagnosis of OSAS in children who snore. However, the childhood OSAS is often neglected and unrecognized. We, therefore, report a case of very severe OSAS in a 5-year-old boy who was sucessfully treated with continuous positive airway pressure(CPAP) treatment. Interestingly, the patient was comor-bid with the attention deficit hyperactivity disorder. Prior to the initial visit to us, adenotonsillectomy had been done at the age of 4 with no significant improvement of apneic symptoms and heavy snoring. On the initial diagnostic procedures, marked degree of snoring was audible even in the daytime wake state and the patient was observed to be very hyperactive. Increased pulmonary vascularity with borderline cardiomegaly was noted on chest X-ray. The baseline polysomnography revealed that the patient was very sleep-apneic and snored very heavily, with the respiratory disturbance index(RDI) of 46.9 per hour of sleep, the mean SaO2 of 78.8%, and the lowest SaO2 of 40.0%(the lowest detectable oxygen level by the applied oxymeter). The second night polysomnography was done for CPAP titration and the optimal pressure turned out to be $8.0\;cmH_2O$. The applied CPAP treatment was well tolerated by the patient and was found to be very effective in alleviating heavy snoring and severe repetitive sleep apneas. After 18 months of the CPAP treatment, the patient was followed up with nocturnal polysomnography(baseline and CPAP nights) and clinical examination. Sleep apneas were still present without CPAP on the baseline night. However, the severity of OSAS was significantly decreased(RDI of 15.7, mean SaO2 of 96.2%, and the lowest SaO2 of 83.0%), compared to the initial polysomnographic findings before initiation of long-term CPAP treatment. Wechsler intelligence tests done before and after the CPAP treatment were compared with each other and surprising improvement of intelligence(total 9 points, performance 16 points) was noted. Clinically he was found to be markedly improved in his attention deficit hyperactive behavior after CPAP treatment, but with minimal change of TOVA(test of variables of attention) scores except conversion of reaction time score into normal range. On the chest X-ray taken after 18 months of CPAP application, the initial cardiopulmonary abnormalities were not found at all. We found that the CPAP treatment in a young child is very effective, safe, and well-tolerated and also improves the co-morbid attention deficit hyperactive symptoms. Overall, the growth and development of the child has been facilitated with the long-term use of CPAP. Cardiovascular complications induced by OSAS have been also normalized with CPAP treatment. We suggest that early diagnosis and active treatment intervention of OSAS in children are crucial in preventing and ameliorating possible serious complications caused by repetitive sleep apneas and consequent hypoxic damage during sleep.

Background : Most current research using prognostic scoring systems in critically ill patients have focused on prediction using the first intensive care unit (ICU) day data or daily updated data. Usually the mean ICU length of stay in Korea is longer than in the western world. Consequently, a more cost-effective and practical prognostic parameter is required. The principal aim of this study was to assess the prognostic value of the seventh day(7th day : the average mean ICU length of stay) APACHE III score in a medical intensive care unit. Methods : 241 medical ICU patients from July 1997 to April 1998 were enrolled. The 1st and 7th scores were measured by using the APACHE III scoring system and compared between survivors and non-survivors. Logistic regression analysis was performed to determine the relationship between the $1^{st}$ and $7^{th}$ APACHE III scores and the mortality risk. Results : 1 )The mean length of stay in the ICU was $10.3{\pm}13.8$ days. 2)The mean $1^{st}$ and $7^{th}$ day APACHE III scores were $59.7{\pm}30.9$ and $37.9{\pm}27.7$. 3) The mean $1^{st}$ day APACHE III score was significantly lower in survivors than in non- survivors($49.9{\pm}23.8$ vs $86.3{\pm}32.3$, P<0.0001). 4)The mean $7^{th}$ day APACHE III score was significantly lower in survivors than in non- survivors($30.1{\pm}18.5$ vs $80.1{\pm}30.4$, P<0.0001). 5)The odds ratios among the $1^{st}$ and $7^{th}$ day APACHE III scores and the mortality rate were 1.0507 and 1.0779 respectively. Conclusion : These results suggest that the seventh day APACHE III score is as useful in predicting the outcome as is such like the first day APACHE III score. Therefore, in comparison to the daily APACHE III score, measuring the $1^{st}$ and $7^{th}$ day APACHE III scores are also useful for predicting the prognosis of critically ill patients in terms of cost-effectiveness. It is suggested that the $7^{th}$ day APACHE III score is useful for predicting the clinical outcome.
Background : A decreased level of serum arginine vasopressin(AVP) and an increased sensitivity to an exogenous AVP is expected in patients with septic shock who often require a high infusion rate of catecholamines. The goal of the study was to determine whether an exogenous AVP infusion to the patients with septic shock would achieve a significant decrement in infusion rate of catecholamine vasopressors while maintaining hemodynamic stability and adequate urine output. Method : Eight patients with septic shock who require a high infusion rate of norepinephrine had received a trial of 4-hour AVP infusion with simultaneous titration of norepinephrine. Hemodynamic parameters and urine output were monitored during the AVP infusion and the monitoring continued up to 4 hours after the AVP infusion had stopped. Results : Mean arterial pressure showed no significant changes during the study period(p=0.197). Norepinephrine infusion rate significantly decreased with concurrent AVP administration(p=0.001). However, beneficial effects had disappeared after the AVP infusion was stopped. In addition, hourly urine output showed no significant changes throughout the trials(p=0.093). Conclusion : Concurrent AVP infusion achieved the catecholamine vasopressor sparing effect in the septic shock patients, but there was no evidence of the improvement of renal function. Further study may be indicated to determine whether AVP infusion would provide an organ-protective effect to the septic shock patients.

Background : 'Major pulmonary thromboembolism' is defined as right ventricular (RV) dysfunction, with or without shock, accompanied by significant morbidity and mortality. In this study, those with major pulmonary thromboembolism were divided into the shock and RV dysfunction only groups, and then investigated the mortality and complications in thrombolysis or anticoagulation, respectively. Methods : In a retrospective study, between January 1995 and December 2004, 60 eligible patients with a major pulmonary thromboembolism, admitted in Asan Medical Center, were included. Results : A total of 57 patients were treated with medical therapy. Thrombolysis was performed in 13 patients (23%) and anticoagulation in 44 (77%). There were no differences in the APACHEII and SOFA scores between the two groups. 6 (46%) and 11 (25%) patients died in the thrombolysis and anticoagulation groups, respectively (p=0.176). In the 19 patients (33%) showing shock, thrombolysis was performed in 9 (47%) and anticoagulation in 10 (53%). 4 (44%) of the 9 patients treated with thrombolytic agents and 3 (30%) of the 10 treated with anticoagulants died (p=0.650). In the 38 patients (67%) showing RV dysfunction only, thrombolysis was performed in 4 (11%) and anticoagulation in 34 (89%). 2 (50%) of the 4 patients treated with thrombolytics and 8 (24%) of the 34 treated with anticoagulants died (p=0.279). Three patients (23%) who underwent thrombolysis had a major bleeding episode, compared with 2 (5%) who were treated with anticoagulants (p=0.072). Conclusion: The results of our study showed that thrombolysis did not lower mortality and tended to increase major bleeding compared with anticoagulation in both the shock and RV dysfunction only groups. Further evaluation of the efficacy and safety of thrombolytic therapy for major thromboembolism appears warranted in Korea.
In this study, we investigated the effects of frankincense essential oil (BSEO) on the immune cell change in the lung, BALF and PBMC using a mouse model of asthma. BALB/c mice after intraperitoneal OVA sensitization (day 1) were challenged intratracheally with OVA on day 14. Then, the asthma was induced by repeated OVA inhalation challenged. The asthma induced mice group inhaled 0.3% BSEO for 30 minutes per trial, three times a week, for 8 weeks using the nebulizer. After 12 weeks from the experiment, the mice was killed and the lung, bronchoalveolar lavage fluid (BALF) and peripheral blood mononuclear cell (PBMC) were obtained. Next, the change of immune cells inside the separated tissues was observed to identity the effects of BSEO on the allergic asthma mice. In conclusion, the hypersensitive reaction of airway to the bronchoconstrictor in the allergic asthma induced mice was effectively suppressed in Frankincense group, in Bermagot, Eucalyptus, Chamomile, Marjoram and Frankincense groups, the natural aromatic essential oil groups. Furthermore, it was also confirmed that the weight of lung, total number of alveolus cells and the number of BALF, MNL and DLN increased after inducing allergic asthma were reduced. BSEO suppressed the percentage of $CD3e^+/CD19^-$, $B220^+/CD23^+$ and $CD11b^+/Gr-1^+$ cells in the lung tissue of allergic asthma mice. Moreover, BSEO also reduced the percentage of $CD4^+/CD8^-$, $B220^+/CD23^+$ and $CD3^+/CCR3^+$ cells in BALF. In addition, the percentage of $CD3e^+/CD19^-$, $CD3^+/CD69^+$ and $B220^+/CD23^+$ cells in PBMC was reduced. The results of this study indicate that BSEO would be effective to treat allergic asthma by the immune control suppressing the activity of immune cells in each tissue.
