Objectives: The purpose of this study was to evaluate the efficacy and tolerability of osmotic release oral system-methylphenidate (OROS-MPH) in children with attention-deficit hyperactivity disorder (ADHD) and comorbid psychiatric disorders. Methods: This was an 8-week open label study of OROS-MPH monotherapy. The subjects were 113 children with ADHD aged 6-12 years. Outcome measures were the Korean version of the parent ADHD Rating Scale (K-ARS), Korean version of the Conners Parent Rating Scale (K-CPRS), Clinical Global Impression-Severity and Clinical Global Impression-Improvement. Side effects were monitored using Barkley's Side Effect Rating Scale. We compared the change-over-time in the mean scores of the outcome measure according to the comorbidity of disruptive behavior disorder, depressive disorder, anxiety disorder, and tic disorder. Results: The mean K-ARS and K-CPRS scores were significantly decreased, regardless of the comorbidity. The mean doses of OROS-MPH and dropout rate did not differ significantly according to comorbidity. The OROS-MPH was well tolerated, regardless of the comorbidity. However, children with tic disorder reported a higher frequency of tics or nervous movements between the $2^{nd}\;and\;8^{th}$ week than those without tic disorder. Conclusion: The OROS-MPH is effective for decreasing the symptoms of ADHD, and it is well tolerated, even by patients with comorbid psychiatric disorders.

Purpose: This study is to conduct a comparative analysis of influencing factors on the experience of mammography targeting ordinary women and outpatients. Methods: The target subjects were 116 ordinary women and 105 outpatients, and the study period was around 8 months from May to December. Results: When mammography experience was examined, it was found that mammography experience was conducted in 44.8% of ordinary women and 59.0% of outpatients, but this study showed that there was a statistically significant difference. When the relation between the characteristics of the targeted objects and the experience of mammography was examined, it was found that ordinary women have a lot of experience when they have regular exercises and a high health belief. On the other hand, in case of outpatients. mammography experience was more frequent in the older group. In addition, outpatients had experiences in breast-related diseases or high self-efficacy. It was also found that the influencing factors on the experience of mammography were a high health belief in case of ordinary women, and old ages and high self-efficacy in case of outpatients. Conclusions: In order to increase the rate of conducting early detection behavior for mammography, it is needed to conduct an intervention that increases health belief for ordinary women, while it is effective to conduct an intervention that increases self-efficacy for outpatients.
In this study, the anti-osteoarthritis effects of Cynanchum wilfordii, Phlomis umbrosa, and Angelica gigas extract (CPAE), observed and confirmed in previously clinical studies were further investigated by in vitro and in vivo studies. Anabolic biomarkers related to healthy cartilage maintenance, such as aggrecan, type II collagen ${\alpha}$-1 (Col2a1), sex determining region Y-box-9 (Sox-9), and catabolic biomarkers related to osteoarthritis, such as cyclooxygenase-2 (Cox-2), matrix metalloproteinase-13 (Mmp13), and nuclear factor kappa-light-chain-enhancer of activated B cells ($Nf{\kappa}b$), were evaluated by quantitative reverse transcriptase polymerase chain reaction and reporter gene assay. In vitro study results showed significant changes in both anabolic and catabolic biomarkers. For anabolic factors, significant changes in the level of aggrecan (P<0.05), Col2a1 (P<0.05), and Sox-9 (P<0.01) activation were shown after treatment of cartilage cells with CPAE (50 ng/mL) with similar efficacy compared to insulin growth factor, the positive control (100 ng/mL). For catabolic factors, significant changes in the inhibition activity of Cox-2 (P<0.05), Mmp13 (P<0.01), and $Nf{\kappa}b$ (P<0.05) were shown for CPAE (50 ng/mL) with similar efficacy compared to Celecoxib, the positive control ($10{\mu}M$). In the in vivo carrageenan-induced paw edema model study results showed that CPAE-treated groups (100 mg/kg) and Celecoxib-treated groups (60 mg/kg) showed comparably significant efficacy of inhibition by 37.1% and 52.1%, respectively. Furthermore, CPAE (200 mg/kg) showed similar effect to Celecoxib (60 mg/kg) with an inhibition rate of 54.3%. This result confirms that CPAE effectively inhibited the inflammation-induced osteoarthritis symptoms.

A partial response or resistance to chemotherapeutic agents is considered as a main obstacle in treatment of patients with cancer, including breast cancer. Refining taxane-based treatment procedures using adjuvant or combination treatment is a novel strategy to increase the efficiency of chemotherapy. PPM1D is a molecule activated by reactive oxygen species. whose expression is reported to modulate the recruitment of DNA repair molecules. In this study we examined the impact of arsenic trioxide on efficacy of paclitaxel-induced apoptosis in paclitaxel-resistant MCF-7 cells. We also investigated the expression of PPM1D and TP53 genes in response to this combination treatment. Resistant cells were developed from the parent MCF-7 cell line by applying increasing concentrations of paclitaxel. MTT assays were applied to determine the rate of cell survival. DAPI staining using fluorescent microscopy was employed to study apoptotic bodies. Real-time RT-PCR analysis was also applied to determine PPM1D mRNA levels. Our results revealed that combination of arsenic trioxide and paclitaxel elevates the efficacy of the latter in induction of apoptosis in MCF-7/PAC resistant cells. Applying arsenic trioxide also caused significant decreases in PPM1D mRNA levels (p<0.05). Our findings suggest that arsenic trioxide increases paclitaxel-induced apoptosis by down regulation of PPM1D expression. PPM1D dependent signaling can be considered as a novel target to improve the efficacy of chemotherapeutic agents in resistant breast cancer cells.
Objectives : This study was performed to evaluate the general distribution and the efficacy of oriental medical treatment for low back pain. Methods: We have selected of the moxa bucket moxibustion. We make a comparative study of the thermodynamic characteristics of moxa bucket moxibustion. We examined combustion times, temperatures, temperature gradients in each period during a combustion of moxa bucket moxibustion made by oak wood.

Female was more than male in the ratio of 1:1.2, and thirties and seventies 25% the most, the acutest phase 46.3% the most, reason unknown 33.8% the most, Grade III 50% the most, L.B.P. only 51.3% the most, the day of 6-10 30% the most, compression Fx 30% the most. 2. In the total treatment result, the good was 51.3%, the excellent 22.5%, the fair 17.5%, the poor 8.8% in order. About 'the effective rate'(the percentage of positive effective treatment cases) of each distribution, the fifties 100% the most, the acutest phase 97.3% the most, the slip down, weight lifting, overuse 100% the most respectively, Grade III 97.5% the most, L.B.P. only 95.1% the most, the day of 11-15 100% the most, HN.P. 93.3% the most. Conclusions : We have known the efficacy of oriental medical treatment for L.B.P. was good and early treatment was better than late treatment and main cause of L.B.P. was degenerative change.
The aim of present study was to determine the efficacy of immunotherapy with paternal lymphocytes for unexplained infertility. It has been apparent that reproductive success may be affected by the presence of abnormal autoantibodies. Unexplained infertility and repeated pregnancy wastage has been reported in the presence of abnormal autoantibodies. These data suffest that abnormal immune function may be an important pathologic entity contributing subfertility in patients with unexplained infertility. Therefore, immunotherapy may be a possible treatment modality for patients with unexplained infertility. Some investigators have reported that a proportion of infertile couples with repeatedly unsuccessful ET showed close histocompatibility similar to those of spontaneous recurrent abortion. Recently, it has been noted that immunotherapy with paternal lymphocytes achieves a high efficacy in preventing subsequent abortion in women with primary recurrent abortion of unknown cause, which was mediated by immune reaction including blocking antibody. To substantiate the hypothesis, we applied immunotherapy preceding Peritoneal Oocyte and Sperme transfer (POST) to 43 patients, 47 cycles of 82 patients, 89 cycles with at least three previous IUI failure from April, 1993 to February, 1995. There were no significant differences between treatment and control group in clinical response and hormonal response to controlled hyperstimulation. there was no significant difference between treatment and control group in pregnant rates per cycles (42.6% versus 28.6%), but a significantly lower abortion rate per pregnancy in treatment group, with 10.0% (2/20) compared with 50.03% (6/12) in control group. This study may suggest that immune therapy for patients with unexplained infertility with paternal lymphocytes might be beneficial.
To evaluate the effect of Yuldahansotang(YHT) water extract on cultuted mouse spinal sensory neuron which was inhibited by xanthine oxidase(XO) and hypoxanthine(HX)-induced oxigen radicals, MIT assay, NR assay, Neurofilament enzymeimmuno assay and LDH activity assay were carried our after the cultured mouse spinal sensory neuron were preincubated with various concentrations of YHT water extract for 3 hours prior to exposure of XO/HX. The results obtained were as follows: 1. XO/HX, a oxigen radical, decreased the survival rate of the cultured mouse spinal sensory neuron cells on NR assay and MTT assay. 2. MTT50 value and NR50 value pf XO/HX were 20 mU/ml XO/0.2 mM HX and 40 mU/ml XO/0.2 mM HX. 3. YHT water extract have efficacy of increasing neurofilament. 4. YHT water extract have efficacy of increasing LDH activity. From above the results, It is concluded that YHT has marked efficacy as a treatment for the damages caused in the XO/HX-mediated oxidative process.
Purpose: This study was to analyse the factors affecting youth smoking, especially self-efficacy and perceived social norm, based on the stage of change. Methods: A self-reported survey was conducted during the period from the 21 st of April to the 17th of May, 2008. Data were collected from 10,707 students of 12 middle schools in Seoul, Gyeonggi-do, and Incheon. The data were analysed with SPSS/WIN 15.0. Results: The smoking possibility was 2.18 times higher in the male students than in female students, and 1.76 times higher in 8th-grade students and 2.48 times higher in 9th-grade students than in 7th-grade ones. Smoking possibility increased when students had more experience in alcohol, more friends who smoke, or worse relationship with their parents. Also this study showed that high-level self-efficacy and perceived social norm were acting as inhibiting factors of smoking. Conclusion: To reduce the youth's smoking rate, smoking prevention programs should provide educational chances to learn knowledge and skills on how to reject smoking temptation. Also, someone significant like parents should make it clear to the youth that they do not want their children to smoke.
Background: We evaluated the changes in mean arterial pressure (MAP) and heart rate (HR), and the anesthetic and hemostatic effects, after injection of 2% lidocaine containing various concentrations of epinephrine in rats and mice to determine the appropriate concentration of epinephrine in various anesthetic mixtures. Methods: Rats and mice were randomly allocated to experimental groups: 2% lidocaine without epinephrine (L0), 2% lidocaine with epinephrine 1:200,000 (L200), 1:100,000 (L100), and 1:80,000 (L80). Changes in MAP and HR after administration of the anesthetic mixture were evaluated using a physiological recording system in rats. Onset and duration of local anesthesia was evaluated by pricking the hind paw of mice. A spectrophotometric hemoglobin assay was used to quantify the hemostatic effect. Results: MAP increased in response to epinephrine in a dose-dependent manner; it was significantly higher in the L80 group than in the L0 group at 5 min post-administration. The HR was relatively lower in the L0 group than in the L80 group. The time required for onset of action was < 1 min in all evaluation groups. The duration of action and hemostatic effect of the local anesthetic were significantly better in the L200, L100, and L80 groups than in the L0 group. Conclusion: L200 demonstrated relatively stable MAP and HR values with satisfactory efficacy and hemostatic effect. L200 might be a better local anesthetic for dental patients in terms of anesthetic efficacy and safety.
