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%

The authors experienced 52 patients with myasthenia gravis who were diagnosed at the Department of Neurology, Yeungnam University Hospital from August 1985 to January 1996. The following results were obtained through diagnostic evaluation and treatment. 1. The ratio of male to female was 1:1.7 and the most prevalent age group was second decade. 2. The most common initial presentation symptom was ocular(71.2%) and the peak incidence group was stage I (69.3%) according to the modified Osserman's classification. 3. In 16 patients(30.8%), it took more than a year to diagnose due to symptoms which were relapsed and remitting. 4. Of 52 patients, 2 cases were associated with thyroid disease(3.8%) and 2 with insulin-dependent diabetes mellitus(3.8%). 5. All of those who received anticholinesterase and corticosteroid therapy were improved with the exception of 5 cases which were improved after thymectomy and/or plasmapheresis.

The maximal voluntary strength of knee extension and flexion on both the right and left sides was measured in patients with hemiparesis of upper motor neuron type and in a group of normal subjects. Significant differences of maximal voluntary strength were found between male and female but the ratio of flexor to extensor strength did not vary significantly between the sides, between the exs in normal subjects. The maximal voluntary strength of uninvolved side were not reduced significantly but involved side reduced significantly in patients. The ratio of flexor to extensor strength in hemiparetic side was significantly less than the ratio for the normal subjects but not significant difference in uninvolved side of patients. According to the above results, the maximal voluntary strength of flexion was more reduced than that of the extension on lower extremity of hemiparesis patients. The strength ratio of flexion to extension was a useful parameter for guiding the rehabilitation of hemiparesis.

Narcotic analgesics may be added to spinal anesthetics solution to improve the quality of sensorimotor blockade and to produce postoperative pain relief. The opioid-related side effects of respiratory depression, pruritus, nausea, and urinary retension also occur with intrathecal administration and the effects are dose-related. It is difficult to select morphine with spinal anesthetic solution due to fatal side-effect, respiratory depression. Intrathecal morphine dose used for our study was less than 1mg, thereby the risk of respiratory depression was decreased. There was no report that the addition of morphine affected the motor block produced by the local anesthetics in spinal anesthesia. But in our study, we found that 0.9 mg of intrathecal morphine produced prolongation of optimal condition for operation(more than 3 hours duration), and sufficient postoperative pain relief(for about 20 hours) without respiratory depression in 28 out of 30 spinal anesthesia cases. On the other hand, 0.5 mg or 0.7 mg of intrathecal morphine produced sufficient postoperative pain relief without respiratory depression(for about 20 hours), but insufficient prolongation of optimal condition for operation in each 30 cases of spinal anesthesia.

Epileptic seizures of nystagmoid character with the fast -beat to the opposite side of the epileptogenic focus have been described as oculoclonic seizures and epileptic nystagmus. Epileptic nystagmus, especially horizontal, most commonly results from seizure activity involving the occipital cortex, although participation of adjoining portions of the parietal and temporal cortex is possible. The frequency of ictal nystagmus was less than 10% of patients with occipital lobe epilepsy. Although forty-six cases were already reported at the litherature, there was no report in korea. We reported a 20-year old patient who had history of recurrent paroxysmal attacks of epileptic nystagniu, associated with oscillopsia and followed by episodic bilateral blindness and eyelid flutter. Standard and extra occipital electrodes visualized more exact left occipital foci at the videomonitored EEG examination when the patient showed epileptic nystagmus. The ictal Brain SPECT, with the use of 99mTc-HMPAO also localized the seizures to left occipital lobe.

H-reflex is a kind of late respons which can be used for the proximal nerve conduction study. Also it is a useful and widely used nerve conduction technique es to look electrically at the monosynaptic reflex. Although recordable from all muscles theoretically, H-reflexes are most commonly recorded from the calf muscles following stimulation of the tibial nerve in the popliteal fossa. But in this study, We tried to establish the normal data and to evaluate the significance of the H-reflex study in cervical radiculopathy. H-reflexes were recorded from flexor carpi radialis (FCR) muscle, extensor carpi radialis (ECR) muscle, brachioradialis (BR) muscle, and abductor digiti minimi (ADM) muscle in 31 normal adults (62 cases) and 12 patients with cervical radiculopathy. The mean values of H-reflex latency in normal control group were 16.16+/- 1.65 msec in FCR; 15.99+/- 1.25 msec in ECR; 16.47+/- 1.59 msec in BR; 24.46+/- 1.42 msec in ADM. And the mean values of side to side difference of H-reflex latency were 0.47+/- 0.48 msec in FCR; 0.68+/- 0.72 msec in ECR; 0.63+/- 0.43 msec in BR; 22.31+/- 1.24 msec in ADM. Mean values of side to side differences of interlatency time were 0.49+/-0.47 msec in FCR; 0.73+/- 0.62 msec in ECR; 0.79+/- 0.71 msec in BR; 0.69+/- 0.44 msec in ADM. Also, there were no significant differences in H-reflex latency between right and left side. H-reflex tests in patient group with cervical radiculopathy revealed abnormal findings in 11 out of 12 patients. These results suggest that H-reflex in the upper extremity would be helpful in the diagnosis of the cervical radiculopathy.

The objective of this study was to find out whether the unilateral distraction of mandible has an influence on temporomandibular joint and if it does, how significant the influence is. Four beagle dogs were used in this study. Each dog had two implants placed into the left mandible. The mandible was distracted for 14days with an distraction device as an amount of 0.75mm, twice per day after osteotomy between two implants. Each animals were sacrificed at the second, fourth, sixth and eighth week after the total distraction amount of 10.5mm were gotten. Upon embedding and staining, the specimens were evaluated with a light microscope. The results were as follows. 1. For the second week group, the articular cartilage and osteoid seam of temporal bone and condyle were relatively well maintained. There were not any significant differences between distraction side and non distraction side. 2. For the fourth week group, the periosteal reaction was activated and the articular cartilage and osteoid seam of temporal bone and condyle were severely thickened-especially at posterior portion of distraction side. This findings revealed that the unilateral distraction forces has more influence on distraction side than on non distraction side, and on posterior portion than on anterior portion. 3. For the sixth and eighth week group, the thickness of meniscus in distraction side gradually recovered to the initial level. The thickened articular cartilage and osteoid seam of temporal bone and condyle were decreased in distraction side and showed relatively stable in non distraction side. From this results, we suggest that several considerations are required such as using an occlusal splint, maintaining the stability of bone distraction device and evaluating bone distraction rate to minimize the damages of temporomandibular joint tissues in early stage of distraction side.
