Purpose: To describe the prevalence, epidemiological characteristics, and related factors of diabetes mellitus in school personnel. Method：5,384 school personnel (2,638 males 2,746 females) received physical examinations at the Seoul School Health Center in 2002. Using the American Diabetes Association criteria, and fasting blood sugar(FBS) was classified as normal at 110>=FBS, borderline 111-125, and the diabetes group 126<=FBS. Related factors of each group were evaluated by gender. Results： In the diabetes group, there were 4.74% males and 0.8% females, and the borderline group was 6.37% males and 2.22% females. The older age group gad a higher distribution in both males and females in the diabetes group. In the diabetes group, the mean and abnormal rate of BMI, systolic hypertension, diastolic hypertension, total cholesterol, GOT, GPT, and GTP were higher than in the normal group. In life style factor, the diabetes group gad a higher distribution of meat eating and smoking more than 20 years than the normal group. The effect of FBS on BMI, BP(blood pressure), total cholesterol, GOT, GPT, and GTP were investigated after controlling for confounding variables. In the borderline and diabetes group, the mean of BMI, BP, total cholesterol, GOT, GPT, and GTP was higher in dose-response effect. In the logistic multiple regression, the related factors of the diabetes group were hypertension and abnormal GTP in males, and abnormal total cholesterol and GTP in females. In the borderline group, the related factors were meat eating, hypertension, and high GOT in males and the older age group, and hypertension, total cholesterol, and abnormal GTP in females. Conclusions: It is possible to manage all related factors of diabetes mellitus except for age. An appropriate program for health promotion is necessary.

Purpose ： To describe epidemiological characteristics and related factors in school personnel with hypertension. Method ： 5,384 school personnel (2,638 males and 2,746 females) received physical examination at the Seoul School Health Center in 2002. blood pressure(BP) was classified by JNC 7th report. Normal BP is systolic BP <120 and diastolic BP<80, prehypertension BP is 120-139 or 80-89mmHg, stage 1 hypertension BP is 140-159 or 90-99, and stage 2 hypertension >=160 or >=100 mmHg. each group was evaluated by gender. We used multiple regression and logistic regression. Results ： Normotension was 20.13% in males and 48.65% in female, prehypertension 43.4% in males and 38.06% in females, stage 1 hypertension 26.38% in males and 10.99% in females, stage2 hypertension 9.59% in males and 3.2% in females. the older age group had higher distribution of stage 1 hypertension and stage 2 hypertension. The means and abnormal rates of BMI, blood sugar, total cholesterol, GOT, GPT, and GTP was higher when their blood pressure was higher. However, an alcohol habit among lifestyle factors had an inverse effect. Higher Bp was correlated to a higher BMI, FBS, and cholesterol-like dose response. In stage 1 hypertension, the related factors of hypertension for males were BMI, amount of cigarettes smoked, exercise, blood sugar, total cholesterol, and GTP. In stage 1 hypertension, age, BMI, exercise, blood sugar, total cholesterol were related factors in female. In stage 2 hypertension, age and smoking were related factors in male, and age, BMI, and cholesterol in female. Conclusions ： It is possible to intervene in all related factors of hypertension except age through life-style modification and appropriate medical management. Active health promotion is needed in School personnel.

When a drug is prepared in a tablet, the active component represents only a small portion of the dosage form. The other components of the formulation include materials to assist in the dissolution, antioxidants, coloring agents and bulk fillers. The tablets are tested using approved testing methods usually involving separation and subsequent quantification of the active component. Tablets may also be tested by near-Infrared Reflectance spectrometry (NIRS). In the present study, based on NIRS and multivariate calibration methods, a novel and precise method is developed for direct determination of ascorbic acid in vitamin C tablet. Two different tablet formulations were powdered in three different sizes, 63-125 ${\mu}{\textrm}{m}$, and examined. Spectral region of 4750-4950 $cm^{-1}$ / was used and optimized for quantitative operations. Partial least squares (PLS) and multiple linear regression (MLR) methods were performed for this spectral region. The results of optimized PLS and MLR methods showed that reproducibility increase with decreasing grain size and standard error of calibration (SEP) of less than 1% w/w of ascorbic acid and a correlation coefficient of 0.998 can be achieved. The PLS method showed better results than MLR. Seven overdose and underdose samples (prepared in the laboratory to match marketed products) were tested by proposed and iodometric standard methods. A correlation between NIRS predicted ascorbic acid values and iodomet.ic values was calculated ($R^2$=0.9950). Finally, the direct analysis of individual intact tablets in their unit-dose packages (Blistering in aluminum and PVC foils) obtained from market were also carried out and a correlation coefficient of 0.9989 and SEP of 0.931% w/w of ascorbic acid were achieved.

Alzheimer's disease (AD) is the most prevalent form of neurodegenerative disease associated with aging in the human population. This disease is characterized by the following 4 structural changes : Atrophy of the Cortex, Parasympathetic, and other neural cells, the existence of Neurofibrillary tangles (NFTs), and the accumulation of Senile plaques. NFTs and Senile plaques is known to be the index of this disease. Senile plaques disturbs the neutro transmission and depletes of Acetylcholine. So, Recovery of Acetylcholine is the primal objective for treating Alzheimer's disease. So, Inhibiting the activity of Acetylcholine Esterase (AChE), which causes the hydrolysus of acetylcholine into choline and acetate, can be seen as a key role for treating Alzheimer's disease. Increasing body of evidence has been demonstrated that Bee Venom Acupuncture (BV) could compete with complex protein involving in multiple step of $NF-_{\kappa}B$ activation and exert the anti -inflammatory potential of combined inhibition of the prostanoid and nitric oxide synthesis systems by inhibition of IKK and $NF-_{\kappa}B$. The effect of BV through behavioral tests after memory impairment induced by Scopolamine. We examined the improving effect of BV on the Scopolamine (1 mg/Kg, i.p.)-induced memorial impairment using passive avoidance response and water maze tests in the mice. BV (0.84, $1.67\;{\mu}g/ml$) reversed the Scopolamine-induced memorial impairment in dose dependent manner. This study therefore suggests that BV acupuncture method may be useful for prevention of development or progression of AD.

Objective : Choroidal metastases (CMs) are the most common intraocular tumor. Management is mainly radiation therapy with goals of pain control and visual improvement. However, many radiation-related complications are reported. Since gamma knife radiosurgery (GKS) for CM was first reported in 1995, few cases have been reported. We report 7 cases of CMs treated with GKS. Methods : From April 2011 to November 2014, 7 patients with CM underwent GKS. Their median age at treatment was 64 years (range, 51-71 years). Four males and three females were treated. Lung cancer was the most common primary pathology, followed by renal cell carcinoma and stomach cancer. Four patients had multiple cerebral lesions and were treated simultaneously for choroidal lesions. The median marginal dose of 20 Gy (range, 15-25 Gy) was administered at the 50% isodose line. Results : Median follow-up period after GKS was 8 months (range, 2-38.3 months). Four patients expired due to underlying malignancy progression. Except for two patients who were not followed with magnetic resonance image after GKS, all patients showed size reduction in the treated lesions, but a new choroidal lesion appeared in one patient and one recurred. Six of seven patients reported subjectively improved visual symptoms. Visual acuity improved in 2 patients, and 2 were stable upon objective examination. One patient showed no improvement in visual acuity, but ocular pain was relieved; another patient showed improved vision and tumor remission, but visual deterioration recurred. Conclusion : GKS was shown to be safe and effective and should be considered for CM treatment.

Paeonol is a major component found in the Paeoniaceae family such as Paeonia suffruticosa Andrews. Paeonia suffruticosa Andrews has traditionally been used to enhance blood flow and relieve joint pain in east Asian countries including China, Korea and Japan. Current research has shown that paeonol blocked the voltage-gated sodium channel and L-type calcium channel. However, there is a lack of research to reveal the relation between cardiac function and blockade of ion channels by paeonol. Therefore, the aim of this study is to investigate whether paeonol has anti-arrhythmic effects via modulating cardiac ion channels. It is collected that the effects of paeonol on multiple ion channels such as the fast sodium channel and L-type calcium channel from published papers. To incorporate the information on multi-channel block, we computed the effects using the mathematical cardiac model of the guinea-pig and rat ventricular cells (Noble 1998 and 1991 model) and induced early after-depolarizations (EADs) to generate an arrhythmia in the whole heart. Paeonol slightly shortened the action potential duration in the normal cardiac ventricular action potential by the inhibition of sodium channel and L-type calcium channel. Paeonol presented the protective effect from EADs by the inactivation of sodium channel but not L-type calcium channel. Paeonol did not show any changes when it treated on normal ventricular cells through the inhibition of sodium channel, but the protective effect of paeonol through sodium channel on EADs was dose-dependent. These findings suggest that paeonol and its original plant may possess anti-arrhythmic activity, which implies their cardioprotective effects.

Pain control is very important in managing terminal cancer patients and there are several modalities to alleviate their pain. A high dosage of epidural morphine is effective to control terminal cancer pain. Furthermore, to decrease the amount of morphine, adding an alternative adjuvant like ketamine to the morphine regimen is considered helpful for controlling the pain of a terminal cancer patient. A 45 year old male patient with terminal lung cancer had neck pain that was caused by multiple bone metastases. Continuous epidural block was started with 2 mg/day of morphine and the dosage was gradually increased to 90 mg/day in 86 days. 30 mg/day of ketamine was then added to it. Overall, the morphine and ketamine dosages were increased to 564 mg/day and 140 mg/day, respectively, in 11 months until the patient expired. In this case, the high dosage of epidural morphine, 580 mg/day, was administered to control cancer pain without any severe adverse effects.

Background: The intrathecal (IT) $GABA_A$ receptor antagonist, bicuculline (BIC), results in tactile allodynia (TA) through disinhibition in the spinal cord. Such disinhibition is considered to be an important mechanism for neuropathic pain. Agmatine, an endogenous polyamine, has a neuro-protective effect in the central nervous system. We investigated the analgesic effects and mechanisms of agmatine action on BIC-induced TA. Methods: Male Sprague-Dawley rats, weighting 250-300 g, were subjected to implantations of PE-10 into the lumbar subarachnoid space for IT drug injection. Five days after surgery, either $10{\mu}l$ of normal saline (NS) or agmatine ($30{\mu}g$ or $10{\mu}g$) in $10{\mu}l$ NS were injected 10 min prior to BIC ($10{\mu}g$) or NMDA ($5{\mu}g$). We assessed the degree of TA (graded 0: no response, 1: mild response, 2: moderate response, 3: strong response) every 5 min for 30 min. Areas under curves and degree of TA were expressed as mean ${\pm}$ SEM. Results were analyzed using one-way ANOVA followed by a Tukey test for multiple comparisons. P < 0.05 was considered significant. Results: IT BIC-induced strong TA reached its peak and plateaued between 10 to 15 min. IT NS-NMDA induced mild transient TA for up to 15 min. Preemptive IT AG attenuated IT BIC-induced TA dose dependently and preemptive IT AG10 completely abolished the IT NMDA-induced TA. Conclusions: Preemptive IT AG attenuated the IT BIC-induced TA through inhibitory actions on postsynaptic NMDA receptor activation. AG might be a viable therapeutic option in the treatment of neuropathic pain.
