저자들은 만성적인 항경련제 투여가 간질환자들의 청신경계에 미치는 영향을 조사하기 위하여 장기간(12개월 이상)항경련제를 복용한 간질환자 51례를 대상으로 이학적 진찰 및 BAEP검사를 실시하고 정상인의 성적과 비교하여 다음과 같은 결과를 얻었다. 장기간 항경련제를 복용한 간질환자의 BAEP검사의 평균 절대 및 파간잠복기는 대조군과 비교하여 유의한 차이가 없었다. Phenytoin단독투여군의 절대 및 파간잠복기는 대조군에 비해 유의한 차이가 없었다. Carbamazepine단독투여군의 I-III파간잠복기는 대조군과 phenytoin단독투여군에 비해 유의하게 연장되었다(p 0.01). Phenytoin단독투여군과 carbamazepine단독투여군에서 항경련제의 복용기간과 BAEP의 절대 및 파간잠복기사이에는 유의한 관계가 없었다. Phenytoin단독투여군과 phenytoin병합투여군에서 각파의 절대 및 파간잠복기는 서로 유의한 차이가 없었다. 이상의 결과로 볼 때 장기간 항경련제를 복용한 간질환자에서 BAEP의 평균 절대 및 파간잠복기는 정상대조군과 비교하여 유의한 차이가 없었고, 항 경련제의 복용기간에 따른 절대 및 파간잠복기의 유의한 변화가 없는 것으로 생각되었다. This study was performed to verify whether or not chronic anticonvulsansts therapy(≥12 months) is associated with brainstem auditory pathway dysfunction in epileptics. Brainstem auditory evoked potentials were done to 51 epileptics who had been taking long term anticonvulasant. The results were summarized as follows. The mean absolute and interpeak latencies were not significantly different between epileptics and controls. The mean absolute and interpeak latencies were not significantly different between epileptics with phenytoin monotherapy and controls. The mean Ⅰ-Ⅲ interpeak latency of carbamazepine monotherapy was significantly delayed than that of phenytoin monotherapy or controls. There was no significant relationship between latency of BAEP and duration of therapy with either phenytoin or carbamazepine. In epileptics with phenytoin combined therapy, the mean absolute and interpeak latencies were not significantly delayed than those of phenytoin monortherapy.

This study was performed to verify whether or not chronic anticonvulsants therapy(≥12 months ) is associated with peripheral nerve dysfunction in epileptics. Nerve conduction studies were done to 51 epileptics who had been taking long term anticonvulsants therapy over 12 months. The mean age of epileptics was 23 years, and was composed of 29 men and 22 women. The mean nerve conduction velocity(NCV) was not significantly different between epileptics and controls. Compared phenytoin or carbamazepine monotherapy group with controls, the NCV was not significantly different in two groups respectively. In epileptics, the mean NCV was not significantly different between phenytoin and carbamazepine monotherapy group. There was no significant relationship between NCV and duration of therapy with either phenytoin or carbamazepine. In epileptics with phenytoin combined therapy, the mean median sensory NCV was significantly delayed than in those with phenytoin monotherapy.

The purpose of this study was to investigate the effects of eight weeks of muscular training and aerobics exercise on the balance and muscular strength elderly women. 18 subjects were divided into the control group and the execise group. The control group maintained their usual activities and the participated in the program that was designed to muscular training and aerobics exercise. ANOVA revealed significant differences between groups for the balance and the strength. The trend observed in the balance and strength between groups suggest that exercise continued over a longer period of time may increase balance and muscular strength.

완전뇌허혈후 재관류시에 국소뇌혈류, 체성감각유발전위 및 신경학적 회복에 대한 Mannitol과 Thiopental의 효과

The cardiopulmonary bypass or cerebral circulation arrest is often used in the treatment of complex aneurysm or of arteriovenous malformation to decrease the risk of intraoperative aneurysm rupture. Although experimental studies have suggested that some drugs may protect the brain from ischemic injury, there are limitations in maintaining cerebral perfusion arrest without incurring neurologic deficits due to the initiation of detrimental processes including excitotoxic neuronal injury, activation of phospholipases, influx of calcium, and generation of damaging free radicals. The purpose of this study is to determine wheter mannitol or thiopental has any favorable effects on the recovery of neurologic deficits and on the regional cerebral blood flow(rCBF), somatosensory evoked potential(SEP) and electroencephalogram(EEG) in cats which underwent 15 minutes-complete global ishcemia-reperfusion. The complete global ischemia was produced in 38 cats by temporary intrathoracic occlusion of the innominate artery and the subclavian artery following ligation of bilateral mammary arteries and simultaneous induction of hypotension. The cats were allocated randomly to one of 4 treatment groups : (1) control group, 8 cats received equal volume of saline solution : (2) thiopental group, 10 cats received 45㎎/㎏ thiopental intravenously, (3) mannitol group, 10 cats received 2g/㎏ mannitol intravenously, (4) combined mannitol and thiopental group, 10 cats received equal dose of mannitol and thiopental intravenously. The drugs were administrated in a equally divided dosage before and after the ischemic episode. The results were as follos : 1) Eight animals which received saline showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours after the ischemia. 2) Ten thiopental-treated animals also showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours the ischemia. 3) Both mannitol-and combined treated groups showed early recovery of EEG, good recovery of SEP and EEG without the severe postischemic hypoperfusion, and 7 of 10 mannitol-treated animals and 8 of 10 combined treated animals were significantly recovered in all parameters. There were not significant differences in all parameters between the mannitol-and combined treated groups. 4) Thirty-four of 38 animals involved in this 15 minutes-ischemia resulted in the severe neurologic deficits inspite of treatment with mannitol, thiopental or both of them. These results suggest that, in cats, mannitol treatment is effective but not thiopental in preventing severe neurologic injury following complete global ischemia and the duration of complete ischemia should be far less than 15 minutes.

In this paper, the Electromyogram discharges in the muscles mobilized for ground stokes are measured before and after the impact. From the analysis of the aspect of electrical discharge we obtain the following results. 1. In regard to the upper limb, when the player executes the forehand storoke the strongest aspect of discharge of electricity(ADE)appears flexor carpi ulnaris, while strong secondary ADE appear on the brachialis and biceps brachialis. However, in the execution of the backhand stroke, only a weak ADE appears on the triceps brachialis, followed by a momentary, strong ADE on the flexor carpi ulnaris and brachioraialis. 2. In regard to the muscles around the trunk when the player executes the forehand strokes, the strongest ADE appears on the latissimus dorsi with the secondary, strong ADE the deltoid with the backhand strokes, however, the strongest ADE appears on the vastus major. 3. In regard to the muscles of the lower limb when the player executes the forehand strokes, a strong and durative ADE appears on the biceps femoris and gastrocnemius, both of which are posterior muscles. However, after impact of the strokes, a weak ADE appears on the rectus femoris and the vastus medialis both of which are anterior muscles. When the player executes the backhand strokes the anterior and posterior muscles show opposite aspects in the process of contraction and relaxation.

This study was undertaken to evaluate the correlation between urodynamic findings and localization of CNS lesions in patient with voiding disturbance. The patient group consisted of 48 patients (35 male and 13 female) with various localization of CNS lesions confirmed by CT or MRI among which were 9 cerebral cortex, 8 putamen and internal capsule, 6 thalamus and internal capsule, 7 brain stem and 18 spinal core. m and 18 spinal core. Nineteen of the 42 patients with various CNS lesions above sacral crod showed detrusor hyperreflexia. Six of the 7 patients who had suprasacral cord lesion and detrusor hyperreflexia showed detrusor sphincter dyssynergia. In 6 patients with sacral cord lesions, 5 patients showed detrusor areflexa. In summary, detrusor sphincter dyssynergia with detrusor hyperreflexia and detrusor areflexia seemed to be specific urodynamcic pattern of suprasacral spinal cord and sacral cord lesion, respectively. But other CNS lesion showed no consistent specific urodynamic pattern.

The research on the self-consciousness of the health-condition and status of the older people results in the following conclusion. 1. Self-consciousness of health-condition This study shows that most older people think themselves they are in the average or normal condition in their health. The answer are following :(a) Lack of knowledge to check their health condition, (b) General systems of sinility, (c)As the factors to heal those symptoms, individual effort for health improvement and adequate exercise programs. 2. Status of their diet Their meal time was comparably regular and the rice was the primary consumption as their daily meal. Snack, beverages, vegetables and fruits were preferred in their in their consumption habit More than half the older people neither smoke nor drink. 3. Current health status When sick, in most cases, the older people do not resort to the hospitalization but tomedicine. More than half the older people surveyed are in worry of their health. Comparably they do not have that much difficulties in getting up in the morning 72.9%of those surveyed say that often feel tired so that a moderate counter-measure must be devided 4. Detrimental factors to their health Insufficient exercise, poor-self-consciousness, mental fatigue were the main factors in sequence. As above, according to the research on the health condition and status of the older people, the most important things were following; a. Strong spirit to overcome the senility b. moderate exercise c. appropriate leisure-education to help them utilize their leisure time which has been increasing. In addition to it, proper education on health to diagnose their health and the development of the new exercise-program in which the older people can participate are in dire need. Long-term measures and facility expansion and strenuous research on the various programs for the older people are also required.
