- We investigated HBV markers in serum and cerebrospinal fluid of 50 subjects with neurologic disorders or other disorders, who visited Dept. of neurology, college of medicine, Yeungnam University, from April-1 to August-31 1994 and were performed cerebrospinal fluid analysis to investigate the detection rate of HBV markers in cerebrospinal fluid and the possibility of neurologic disorders associated with HBV infection. The results were as follows. The positivity of HBsAg and. HBV prevalence rate in serum were 6 (12.04) and 37 (74.0%). Thf, number of patient with HBsAg, only anti-HBV and no markers were 6 (12.0%), 31 (62.0%) and 13 (26.0%), respectively. The positivity of HBsAg and HBV prevalence rate in cerebrospinal fluid were 3 (6%) and 18 (36.0%). The number of patient with HBsAg, only anti-HBV and no markers were 6 (100.0%), 12 (38.7%) and 0 (0.0%) respectively. The number of patient with virus associated diseases (VAD) and non virus associated diseases (NVAD) were 26 (52%) and 24 (48%). The HBV prevalence rate in serum of VAD and NVAD groups were 88.5% and 58.3% (p<0.05). The HBV prevalence rate in CSF of VAD and NVAD groups were 53.8% and 16.7% (p<0.05). The HBV prevalence rate in serum and CSF of VAD and NVAD groups were 60.9% and 28.6%. As a conclusion, the HBV markers in the CSF were partially detected at the presence of the HBV markers in serum. The prevalence rate of HBV in the CSF was increased at the HBsAg positive in the serum and the CSF was significantly increased at the VAD group than the NVAD group

- This study was undertaken to evaluate the clinical usefulness of magnetic motor evoked potential (MEP) in the diagnosis of stroke and predicting the motor improvement following stroke. The cortical, cervical and lumbar stimulations were performed in the case of 24 healthy controls and 24 to a target muscle between after transcranial stimulation and after cervical or lumbar stimulation. There was no case showing no response in controls. But in 11 out of 24 ischemic patients, we could not get cortical MEP. Mean CMCT of abductor pollicis brevis muscle was not significantly different in controls and stroke patients in whom MEPs were recorded. There were significant differences between mean CMCT of normal controls and that of stroke patients showing MEPs in AH Muscle. MEP Results from testing the stroke patients were correlated with site of lesion, degree of motor weakness and motor improvement after 1 to 2 months. These results suggest that magnetic MEP is easy and useful in electrophysiological test of central motor pathway and is useful indicator for representing the motor weakness and predicting the motor outcome in acute ischemic stroke patients.

Abstract

- The purpose of this study was to evaluate the effect of stroke on hypothalamic-pituitary axis using dexamethasone suppression test. The effects were evaluated according to age, sex, type, size, and lesion site of stroke. There tests were performed in 62 patients with stroke(cerebral infarction, 42 cases : intracerebral hemorrage, 20 cases) and 21 disabled controlled patients without intracranial diseases at Yeungnam University Hospital from June 1992 to June 1993. The results summarized as follows. 1. Cerebral infarction showed significantly higher frequency of DST non-suppression in stroke patients than control (p<0.05). 2. Patients with left hemisphere stroke showed more frequent abnormal neuroendocrine test results (p<0.01). 3. Patients with large infarction revealed strongly non-suppressed DST results(p<0.01). 4. Significantly higher basal cortisol level in patients with cerebral infarction was noted(p<0.01). 5. There are no statistical significance between DST results and sex, age, motor impairment, type of cerebral infarction.
