Drug addiction influences most communities directly or indirectly. Increasing studies have reported the relationship between circadian-related genes and drug addiction. Per2 disrupted mice exhibited more vulnerable behavioral responses against some drugs including methamphetamine (METH). However, its roles and mechanisms are still not clear. Transcriptional profiling analysis in Per2 knockout (KO) mice may provide a valuable tool to identify potential genetic involvement and pathways in enhanced behavioral responses against drugs. To explore the potential genetic involvement, we examined common differentially expressed genes (DEGs) in the striatum of drug naïve Per2 KO/wild-type (WT) mice, and before/after METH treatment in Per2 KO mice, but not in WT mice. We selected 9 common DEGs (Ncald, Cpa6, Pklr, Ttc29, Cbr2, Egr2, Prg4, Lcn2, and Camsap2) based on literature research. Among the common DEGs, Ncald, Cpa6, Pklr, and Ttc29 showed higher expression levels in drug naïve Per2 KO mice than in WT mice, while they were downregulated in Per2 KO mice after METH treatment. In contrast, Cbr2, Egr2, Prg4, Lcn2, and Camsap2 exhibited lower expression levels in drug naïve Per2 KO mice than in WT mice, while they were upregulated after METH treatment in Per2 KO mice. qRT-PCR analyses validated the expression patterns of 9 target genes before/after METH treatment in Per2 KO and WT mice. Although further research is required to deeply understand the relationship and roles of the 9 target genes in drug addiction, the findings from the present study indicate that the target genes might play important roles in drug addiction.
Objectives We analyzed visiting patterns to medical institutions and cost per visit according to the common cold patients aged 0-19 years. We analyzed Korean medical treatment for common cold. Methods Using the Pediatric Patient Sample data of the Health Insurance Review and Assessment Service (HIRA-PPS), we analyzed the data on health insurance claims of approximately 1 million people from 2017 to 2019. The data included the number of patients who visited the hospital due to common cold for the first and second time, the ratio of second visits by type of medical institution, and the status of prescriptions in Korean medical institutions. Results The number of patients visiting healthcare providers for common cold was higher in Western medical institutions than in Korean medical institutions. However, the number of second visits was higher in Korean medical institutions. Acupuncture is the most commonly used medical treatment in Korean medical institutions for common cold. Herbal medicine for common cold was usually prescribed for 2-3 days for children and adolescents. Conclusions Although the average medical cost of Korean medical institutions was higher than that of Western medical institutions, the rate of second visits to Korean medical institutions was higher because of the demand for Korean medical treatment
Objectives : Coptidis Rhizoma has been used for stomach disease. However, its property is so cold that it might be avoided to prescribe for the elderly and the infirm having indigestion or diarrhea. Accordingly, the present study was designed to investigate the protective effects of Coptidis Rhizoma herbal acupuncture extract against acute gastric mucosal lesions induced by compound 48/80 in rats. Methods : The Coptidis Rhizoma herbal acupuncture (CRHA) was injected in Choksamni and Chungwan 1 h before compound 48/80 treatment. The animals were sacrificed under anesthesia 3 h after compound 48/80 treatment. The stomachs were removed and the amount of gastric adherent mucus, gastric mucosal hexosamine, SOD, XO, TBARS and histological examination were performed. Results : The decline of gastric adherent mucus, gastric mucosal hexosamine and the histological defects of gastric mucus were significantly protected by CRHA treatment. Gastric adherent mucus in control group was reduced to $38.2{\pm}5.0%$. CRHA groups significantly protected the loss of mucus to $77.5{\pm}4.9%$. Mucosal hexosamine content showed similar patterns. Mucosal hexosamine content in control group was reduced to $45.2{\pm}6.2%$. CRHA groups significantly protected the loss of mucus to $83.0{\pm}7.0%$. The changes of gastric mucosal SOD and TBARS were recovered by CRHA treatment as well. Conclusions : CRHA showed the protective effects on the acute gastric mucosal lesions induced by compound 48/80 in rats. These results suggest that CRHA may have protective effects on the gastritis.

Recently, sedation is routinely used in children who lacked cooperation in pediatric dental clinics. The purpose of this study is to analyze dental treatment cases in department of pediatric dentistry at Dankook University Dental Hospital associating with sedation during 5 years. From January 2011 to December 2015, information about dental treatment cases in department of pediatric dentistry was collected and reviewed. The information gathered included patient gender, age, sedation type, sedative agents, date of operation, and type of procedure. The proportion of treatment cases with conscious sedation for total treatment cases continued to decline until 2014. On the other hand, the incidence of general anesthesia increased gradually. The frequency of midazolam administration and nitrous oxide inhalation sedation increased recently. The use of conscious sedation was significantly decreased when the age of patient was 3 years or older. The frequency of general anesthesia was similar in all age groups. There was a tendency to perform treatment with deeper sedation when the patient was male than female, and when the pulp treatment was performed together with the restorative treatment than not performed. The frequency of re-treatment within 90 days after restoration treatment decreased as the depth of sedation increased.
The effect of allelochemicals on growth, root nodule nitrogen fixation activity, and ion patterns of soybeans were investigated. We prepared 50 g/L (T50), 100 g/L (T100), and 200 g/L (T200) extract concentrations by soaking fresh red pine needles in a nutrient solution. Adding needles to the nutrient solution increased the content of total phenolic acids, osmolality, and total ions. The total phenolic content in the T50, T100, and T200 extracts were $206{\pm}12.61$, $335{\pm}24.16$, and $603{\pm}12.30$ mg gallic acid equivalents, respectively. The $K^+$, $Mg^{2+}$, $Ca^{2+}$, and $PO_4^{3-}$ content increased by adding needles to the nutrient solutions, whereas $SO_4^{2-}$ content decreased. The growth inhibition of soybeans was proportional to the needle extract concentrations, and the T100 and T200 concentrations resulted in remarkable growth inhibition. On day 20 after treatment, dry weight and nitrogen fixation activity of the root nodules were reduced by the T100 and T200 treatments, whereas the T50 treatment was not difference from the control. After day 10, total ion content in all treatment groups was not different in comparison with the control. However, total ionic content in all treatment groups decreased significantly compared with that in the control after day 20. The lowest total ion value was found for the T200 concentration. The T200 treatment also resulted in significantly reduced $SO_4^{2-}$ content. The amounts of $Mg^{2+}$, $Ca^{2+}$, and $Mn^{2+}$ were higher than those of the control for the T50 treatment on day 10 and for T100 on day 20 after treatment. A significant increase in osmolality was observed in the T200 treatment on day 10 and in the T100 treatment on day 20. These results suggest that under severe allelochemical stress conditions, a remarkable reduction in nodule formation, nitrogen fixation activity, and ion uptake eventually resulted in a decrease in leaf production. Furthermore, increased $K^+$, $Mg^{2+}$, $Ca^{2+}$, $Mn^{2+}$, and osmolality in soybeans exposed to lower concentrations of allelochemicals than the critical stress level helped overcome the stress.
Background and Purpose Through ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$, Dongmu Lee Je-ma supposed the minds of management for Sasang Constitutional Symptoms, which had been accomplished through several steps from his early writings to ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. His basic minds of treatment for disease had been supposed early in ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$ and ${\ulcorner}$Gyukchigo${\lrcorner}$, and had been completed to the Sasang Constitutional Symptoms and the minds of management for it, from ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ written in 1894 to ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. In this paper, I tried to find the minds of treatment of ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$, through classifying and researching the early minds of treatment (presented in ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$, ${\ulcorner}$Gyukchigo${\ulcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$), and the latter minds of treatment (presented in ${\ulcorner}$Dongyi Soose Bowon${\ulcorner}$ written in 1894, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901) Methods It was researched as bibliologically with his writings such as ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$, ${\ulcorner}$Gyukchigo${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ written in 1894, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. Results and Conclusions The conclusions were as follows. 1. At early, Dongmu Lee Je-ma pursued the minds of treatment at the autonomous control through 'Acquaintance and Self-control' based on 'the Knowledge of Nature and Desire', so emphasized 'self-control' as important point in treatment. 2. From ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lcorner}$, Dongmu summarized Sasang constitutional symptoms structurally in view of Morpho-imaginary. In ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lcorner}$ and ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ written in 1894, It was described in view of small organ, but in ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, suggested more updated in view of both large and small organ and to which added the concept of Hot and Cold. 3. Through reinterpreting the concept of interior and exterior disease in ${\ulcorner}$Sanghanrhon${\lcorner}$, the concept of Sasang constitutional symptoms had started as the minds of treatment for individual disease, but in ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, it was accomplished as the minds of broad management for Sasang Constitutional Symptoms. 4. In ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, the broad therapeutic prescriptions for management of Sasang constitutional symptoms were proposed newly, according to the accomplishment of Sasang constitutional symptomatic patterns, so these have different aims and are more important than that proposed previously. 5. The control in view of 'Knowledge and Deed' and the minds of management for Sasang constitutional symptoms are the minds and spirits for treantment and prevention against disease, which can maximize the power of autonomous self-treatment and manage all disease broadly.
Purpose : Surgery is the treatment of choice for resectable non-small cell lung cancer. For patients who are medically unable to tolerate a surgical resection or who refuse surgery, radiation therapy is an acceptable alternative. A retrospective analysis of Patients with stage I non-samll cell lung cancer treated with curative radiation therapy was performed to determine the results of curative radiation therapy and patterns of failure, and to identify factors that may influence survival. Materials and Methods : From 1986 through 1993, 39 Patients with T2N0M0 non-small cell lung cancer were treated with curative radiation therapy at department of radiation oncology, Kyungpook national university hospital. All Patients were not candidates for surgical resection because of either Patient refusal (16 patients), poor pulmonary function (12 patients), old age (7 patients), Poor Performance (2 patients) or coexisting medical disease (2 patients). Median age of patients was 67 years. Histologic cell type was squamous cell carcinoma in 36, adenocarcinoma in 1, large cell carcinoma in 1 and mucoepidermoid carcinoma in 1. All patients were treated with megavoltage irradiation and radiation dose ranged from 5000cgy to 6150cGy with a median dose of 6000cGy. The median follow-up was 17 months with a range of 4 to 82 months, Survival was measured from the date therapy initiated. Results : The overall survival rate for entire Patients was $40.6\%$ at 2 years and $27.7\%$ at 3 years, with a median survival time of 21 months. The disease-free survival at 2 and 3 years was $51.7\%$ and $25.8\%$, respectively. Of evaluable 20 patients with complete response, 15 patients were considered to have failed. Of these, 13 patients showed local failure and 2 patients failed distantly. Response to treatment (p=0.0001), tumor size (p=0.0019) and age (p=0.0247) were favorably associated with overall survival. Only age was predictive for disease-free survival (p = 0.0452). Conclusion : Radiation therapy is an effective treatment for small (less than 3cm) tumors, and should be offered as an alternative to surgery in elderly or infirm patients. Since local failure is the prominent Patterns of relapse, potential methods to improve local control with radiation therapy are discussed.
This study was conducted to assess the morbidity and medical facilities utilization patterns of high school students in urban and rural areas, and to contribute to establishment of school health policies. A questionnaire survey was carried out for 1,979 of one boy's and one girl's high school in Pusan and 1,315 of one boy's and one girl's high school in Kyungnam province from March 27 to April 8, 1989. The summarized result is as follows. The number of students who were sick or injured in one month period was 378.0 of 1,000 students. One sick or injured student experienced 1.2 events on the average and thus the incidence rate was 453.2 per 1,000 students for a month. The morbidity rate of the urban area (550.8) was higher than that of the rural area (306.5) while the rate for girl students (561.9) was higher than that of the boy students (328.3) (P<0.01). Especially, the girl students (740.7) in the urban area showed two times higher morbidity rate than that of the girl students in the rural area. Out of all morbidity respiratory disease for 67.6 percent in urban area and 68.5 percent in rural area and it was followed by gastrointestinal disease and nervous & sensory diseases. The morbid conditions took place at school in 37.5 percent, and at home in 59.8 percent. The absence rate due to morbidity was 4.4 percent out of all morbid students. In addition, 73.5 percent of all morbid student utilized medical treatment, of which the pharmacy accounted for 53.8 percent and 57.5 percent in the urban and rural areas, respectively. The second most common facility utilized was hospital OPD. While there was no student who utilized the school nursing room in the rural area, 1.5 percent of the sick students utilized the school nursing room in the urban area. The most important in selecting medical facility was the distance. By low medical expense was more frequent cited reason for selecting medical facility in rural area (13.6 percent) than in urban area (3.2 percent). Mild illness accounted for 70.3 percent of the reasons for no treatment and 21.8 percent was due to the conflict between school hour and clinic hour. The morbid students mostly suffered from mild respiratory and gastrointestinal disease, and its incidence was the highest rate in the school. Although there was relation between the worry of absence and no-treatment, the school nursing room utilization of students was very insufficient. Therefore, it is required to activate the operation of the high school nursing room by utilizing the specialized personnel.
Purpose: There is considerable variability in rates of hospitalization for patients with community-acquired pneumonia (CAP) in part because of physicians' uncertainty in assessing the severity of illness at presentation. The purpose of the study was to examine the current treatment patterns and factors influencing the Pneumonia Severity Index (PSI) and clinical outcomes in the patient with CAP. Method: The retrospective data collection of the patients with CAP was conducted and the data were reviewed. The collected data included demographic, clinical, laboratory and microbiological medical information. All patients were stratified into three risk groups according to PSI: low risk (PSI score I-II), moderate risk (III) and high risk (IV-V) groups. The examined treatment patterns were the appropriateness of admissions, category of antibiotics used. The prognostic factors associated with PSI and clinical outcomes were examined. Results: One hundred and six patients' medical data were reviewed. The overall appropriateness of admissions was low presenting many of patients were admitted or intensely treated in the hospital despite of lower risk of prognosis and treated with intravenous antibiotics instead of oral fluoroquinolones. Primary pneumonia pathogens were Klebsiella pneumoniae (27%) and Streptococcus pneumoniae (21.6%). Mean LOS was 8.5 days and was significantly longer (10.0days) (p<0.001) in high risk group. The patients with age >65 (p<0.001), diabetes mellitus (p<0.001), mental alteration (p<0.001), and/or $PaO_2$ <60 mmHg (p<0.001) had a tendency to have higher PSI. The prognostic factors associated with longer LOS were age >65 years (p=0.008), mental status alteration (p<0.001), dyspnea (p=0.002) and PSI score (p=0.001). The prognostic factors associated with mortality were congestive heart failure (p=0.038), systolic blood pressure <90 mmHg (p=0.002) and arterial pH <7.35 (p=0.013). Conclusion: Most of patients were found to over-utilize medical service according to appropriateness of admissions. The elderly, mentally altered patients with low $PaO_2$ had higher PSI score with increased risk of LOS. The mortality could be increased in the patient with disease state of congestive heart failure, high blood pressure, and/or acidosis.
Dose rate regulated tracking is known to be an efficient method which adaptively delivers tracking treatments when patient breathing is irregular. The Motion Management Interface (MMI, Varian Medical System, CA), which provides beam on/off switching during treatment is available for clinic. Study is to test if delivering the adaptive tumor tracking is feasible for irregular breathing using beam switching with MMI. 55 free breathing RPM traces acquired from lung cancer patients are used. The first day RPM traces of the patients are utilized to design preprogrammed tracking MLC patterns, of which periods are intentionally reduced by 20% in order to catch up the variation of patient breathing irregularity in the treatment day. Eligibility criteria for this technique are the variation of amplitude and period less than 20%. An algorithm which determines beam on/off every 100 ms by considering the preprogrammed (MLC) positions and current breathing positions is developed. Tracking error and delivery efficacy are calculated by simulating the beam-switching adaptive tracking from the RPM traces. Breathing patterns of 38 patients (70%) met the eligibility criteria. Tracking errors of all of the cases who meet the criteria are less than 2 mm (average 1.4 mm) and the average delivery efficacy was 71%. Those of rest of the cases are 1.9 mm and 48%. Adaptive tracking with beam switching is feasible if patient selection is based on the eligibility criteria.
