Since the 1960's, Korea has achieved rapid economic growth, longer life expectancy, accelerated urbanization and a westernization of diet. Cardiovascular disease has become the leading cause of death; however the prevalence of ischemic heart disease(IHD) remains low. A cross-sectional multiphasic screening service for 18,426 persons aged 30 64 years in a Medical Aid Program in Kyonggi-do Province was conducted from 1991 to 1993. Total cholesterol(TC), Fasting blood glucose(FBG), blood pressure(BP), and electrocardiographic(EKG) data were collected. The result as follows; 1. On the EKG findings, the age-adjusted prevalence of myocardial ischemia and myocardial infarction was 1.45% in men and 2.06% in women. 2. The mean blood pressure was 122.9/78.8mmHg. The age-adjusted prevalence of hypertension was 11.05% in men and 9.02% in women. The prevalence of hypertension showed increasing tendency according to age increase. In all age group, the prevalence of hypertension was higher in men than women. 3. The mean total cholesterol level was 184.4mg/dl in men and 189.2mg/dl in women. The age-adjusted prevalence of hypercholesterolemia was 4.88% in men and 5.67% in women. The total cholesterol level showed increasing tendency according to age increase, except 55 64 age group in men. 4. The prevalence of hyperglycemia is 5.8%. The age-adjusted prevalence of hyperglycemia is 6.72% in men and 4.50% in women. The prevalence of hyperglycemia showed increasing tendency according to age increase. 5. On the EKG findings, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension than normal, in all age group of men and women less than 40 years-old. Only in women more than 40 years-old, the prevalence of myocardial ischemia and myocardial infarction was higher in hypercholesterolemia and hyperglycemia. Nevertheless there is not statistical association between ischemic heart disease and previous risk factors in other age group, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension, hypercholesterolemia and hyperglycemia than normal. The result of this study suggest that relationships between major risk factor of ischemic heart disease and ischemic heart disease is similar to existing theory.

Acute infarcts of the anterior inferior cerebellar artery (AICA) territory are unusual. Furthermore incomplete AICA infarcts are perplexing because of its variations of vascular anatomy and inconsistent clinical features. We present a case with clinical features of AICA infarction, which consist of ipsilateral peripheral-type facial palsy, vertigo, and contralateral facial and upper limb sensory changes without motor weakness. The patient had hypertension and was a current smoker. The high signal intensity on inferior pontine tegmental area was found on MRI and the R2 interneuronal dysfunction was note on Blink reflex. The angiographic findings didn't show any focal vascular lesions, which is contrary to the pathogenesis of AICA infarction published previously. On the clinical ground, the present case reserves to attention in that patients with peripheral-type facial palsy should be properly evaluated and with thorough neurological examination and we could differentiate between the incomplete AICA infarcts such as Gasperini syndrome and Bell's palsy.

A 37-year-old male patient was transferred from a local orthopedic clinic due to status epilepticus following a myelography with diatrizoate. On his laboratory findings, metabolic acidosis was prominent. Non-enhanced brain CT scan showed a high densinty in the subarchnoid space. With careful respiratory support, hydration, correction of acid-base balance, administration of dexamethasone, and anticonvulsant therapy, he completely recovered after 3 days. Diatrizoate is an ionic, iodinated and hyperosmolar X-ray contrast medium. It must not be injected intrathecally because of the risk to the central nervous system. The possible mechanisms are anaphylactic reaction due to iodine hypersensitivity, hyperosmolar effect, and direct chemotoxicity by ionicity and chemical structure itself.

OBJECTIVE: In accordance with the increasing number of elderly people in our society, the incidence of pedicle screw fixation which is a technically demanding procedure and requires a lengthy operation time has increased in the patients with lumbars instability over 60 years old. To ascertain the outcome and efficacy of the pedicle screw fixation in patients over 60 years old, we analyzed the surgical results including complications. PATIENTS AND METHOD: From May, 1994 to September, 1997, we assessed 30 patients over 60 years of age and 159 patients under the age of 60 with lumbar spinal instability who underwent surgery of pedicle screw fixation and compared with the results of surgery between two groups. RESULTS: For the elderly, the average operation time was 244 minutes and the transfusion amount was 3.3 pints. For younger patient the average operation time was 246 minutes and the transfusion amount was 3.2 pints. Four surgical complications occurred; two patients with voiding difficulty, one patient with heart problem, and a patient with DIC(Disseminated Intravascular Coagulation). However, all complications were controlled without further problems. The success rate in the elderly was 60%, which was lower than the success rate of 76% among younger patients. CONCLUSION: Considering the condition of the diseases in the elderly and the fact that the operations were performed without any major problems, these results are acceptable. Based on our analysis, it is our view that advanced age per se should not be regarded as a contraindication for pedicle screw fixation.

The therapeutic efficacy of antipsychotic drugs is generally attributed to their ability to block dopamine D2 receptors. Classical D2 antagonists are not effective to treat negative symptoms and produce extrapyramidal side effects. On the other hand, atypical antipsychotic agents ameliorate negative symptoms without producing extra-pyramidal side effects, and it is reported to be associated with blockade of serotonin 5-HT2 receptors. The purpose of this study was to evaluate the effect of risperidone on neuroreceptors in the rat brain by quantitative autoradiography method. In acute treatment group, risperidone was injected into peritoneal cavity of male Wistar rats with dose of 0, 0.1, 0.25, 0.5, 1,0 and 2.0mg/kg in each Group(5/group), and they were decapitated after 2 hours. In chronic treatment group, risperidone was injected with dose of 0, 0.1, and 1mg/kg(I.P.) for 21 days and decapitated after 24 hours following last treatment. The effect of risperodone on the binding of [3H]spiperone to 5-HT2 and D2 receptors were analysed in 4 discrete regions of the striatum, nucleus accumbens, and frontal cortex by quantitative autoradiography. Acute treatment with risperidone reduced cortical 5-HT2 specific [3H]spiperone binding to 32% of vehicle-treated control. Subcortical 5-HT2 specific [3H]spiperone binding was not affected at all dose groups whereas a significant reduction (57%) in D2 specific [3H]spiperone binding was observed in risperidone treated group at doses of l-2mg/kg. Chronic treatment with risperidone produced a decrease in the maximal number of cortical 5-HT2 receptors to 51% and 46% of control in 0.1mg/kg & 1mg/kg treated group respectively. In conclusion, risperidone is a cortical serotonin receptor antagonist with relatively weak antagonistic action on dopamine receptors. These effects on neuroreceptors may explain the therapeutic effect of risperidone as a atypical antipsychotic agents.
