Abstract PDF: 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

Abstract PDF

To evaluate the risk factors which are related to recurrence of ischemic stroke, we selected subjects who were admitted to YNUH due to recurrent stroke and compared their risk factors with non-recurred group- who suffered from single ischemic stroke. In the subjects, 55 of them are men and 22 were women and in the non-recurred groups, 84 of them were men and 40 were women, Subject's age ranged from 29 to 86 years (Mean 62.5years), and non-recurred group's age ranged from 27 to 90 years (Mean 60.7years), Peak incidence of ischemic stroke is in the 7th decade in both groups. Age and sex are not statistically significant for recurrence of ischemic stroke. The patient's history of diabetes mellitus, myocardial infarction, atrial fibrillation, transient attack and type or site of ischemic stroke had no significant effect statistically on the recurrent ischemic stroke. However, when the patient had previous history of hypertension or systolic blood pressure more than 160 mmHg and diastolic more than 95mmHg, there was substantial difference (P<0.05) between the two group in the recurrence of ischemic stroke. According to the above results, hypertension is most likely significant risk factor of the recurrence of ischemic stroke within 2 yers after initial one. Therefore, adequate treatment of the hypertension is important for the prevention of ischemic stroke. Further study is required for searching other risk factors.

Abstract PDF: The objective of the present study was to identify the characteristics of phospholipase C (PLC) isozymes purified from bovine brain and to investigate their interrelationship with G protein. The purified PLC isozymes β, γ and δ were obtained and the characteristics of PLC activity on various concentrations of free Ca²⁺ were observed. The activity of PLC was increased with increasing Ca²⁺ concentration and the activity PLC δ was increased higher in the presence of phosphatidyl choline (PC) than in the absence of PC. For vesicle formation as the structure of cell membrane, cholic acid and deoxycholic acid as detergent on phosphatidylinositol bisphosphate (PIP₂) substrate containing PC were used, and then the activity of PLC isozymes were increased with increasing concentration of cholate, from 0.2% to 1% and were increased slightly in deoxycholate. In the PIP₂ containing phospholipid and glycolipid as brain extract, the activity of PLC isozymes were checked in 0.2-1% cholic acid. The activities of PLC isozymes were continuously increased up to 1% cholic acid. The quantitation of PLC isozymes from several bovine organs by radioimmunoassay was made. Brain was the most sufficient organ in terms of amount of PLC β and δ. A large amount of PLC δ was existed in adrenal gland. The binding capacity of GTPrS and G protein was observed and other observations of the binding effect of GTPrS-G protein and PLC monoclonal Ab-Protein A from tissue homogenate with PLC were made. From the observation the binding capacity was revealed the range of 0.11-1.49%. The effects of each type of G protein on the percent activity of purified PLC isozymes were observed. From the observation, activities of isozymes were increased in Goa & Gmix, and the activities of PLC β and δ were increased in Gβγ and Gia. Activities of PLC β and γ were decreased in Gta but PLC δ increased.

Abstract PDF: To obtain the basic data of prognosis of acute carbon monoxide (CO) intoxication, one hundred and sixteen cases of CO intoxication defined by carboxyhemoglobin (COHb) and admitted via emergency room of Yeungnam University Hospital from Oct. '85 to April' 89 have been clinically analyzed and evaluated, including delayed postanoxic encephalopathy (DPE) and the following results were obtained. 1. The ratio of male to female was 1:1.5 and mental state was drowsy mostly (26.2% of 116 cases) 2. The more disturbed the mental state, the more decreased was the arterial pH and PaCO₂, which may be the result of metabolic acidosis. 3. The early laboratory findings in patients of CO intoxication were as follows: leukocytosis-65.5%, increase of hematocrit-23.3%, hyperglycemia-19.8%, increase of GPT-19.8% increase of creatinine-0.9% and glucosuria-12.1%. 4. The early findings of EKG were abnormal in 35.3%: change of rhythm-25.0%, abnormal ST segment 15.5% (change of rhythm and abnormal ST segment-5.2%) but the conduction disorder was not present. 5. The abnormal EEG above mild degree was 93.1%, of which moderate was most frequent (80.2%). 6. The incidence of DPE was 7.8% among all admitted CO patients. DPE cases had long duration of exposure time (8 hours), severe leukocytosis (20,000) and an abnormal EEG (MA).

Abstract PDF: The author studied 20 healthy adults (20 hands) as a control and 30 patients (40 hands) with carpal tunnel syndrome to evaluate the clinical usefulness of measuring nerve conduction velocity after wrist flexion in diagnosis of carpal tunnel syndrome. The median nerve conduction velocity over wrist to finger segment was measured before and after wrist flexion for 1, 2 and 5 minutes, using belly-tendon method for motor nerve distal latency (MNDL) and antidromic method for sensory nerve conduction velocity (SNCV). The results were as follows: 1. In control group, MNDL increased in 1 hand and SNCV decreased in 2 hands after wrist flexion. In patient group, MNDL increased in 2 hands and SNCV decreased in 3 hands after wrist flexion. 2. In both control and patient group, there were no significant changes in mean values of SNCV and MNDL between before and after wrist flexion. 3. Phalen's wrist flexion test was positive in 5 percent of control and 60 percent of patient group. 4. Tinel's sign was present in 10 percent of control and 33 percent of patient group.

Abstract PDF: Eaton Lambert Syndrome (ELS) is a disorder of neuromuscular transmission. The defect of neuromuscular transmission is due to decrease in the release of acetylcholine quanta from nerve terminal. This syndrome is frequently associated with bronchogenic carcinoma. The diagnosis is established by electromyography, which characteristically shows 1) low amplitude of evoked compound muscle potential to a single supramaximal stimulus on nerve, 2) significant decremental response at low rates of stimulation 3) marked incremental response at high rates of stimulation. Our patient is 52year old man with dyspnea, coughing and muscle weakness of proximal lower limbs. He has small cell lung cancer and associated with ELS, Superior vena cava syndrome and has metastatic lesion on right supraclavicular lymph node confirmed by pathology. Metastatic mass and SVC syndrome are marked improved following chemotherapy and radiotherapy, however follow up EMG finding does not improved. We are here reporting one case which considered compatible for ELS, with a few elementary reviewed literatures.

Abstract PDF

Nerve conduction studies help delineate the extent and distribution of the neural lesion. The nerve conduction was studied on upper (median, ulnar and radial nerves) and lower (personal, posterior tibial and sural nerves) extremities in 83 healthy subjects 23 to 66 years of age, and normal values were established (Table 1). The mean motor terminal latency (TL): median, 3.6 (±0.6) milliseconds; ulnar, 2.9 (±0.5) milliseconds; radial nerve, 2.3 (±0.4) milliseconds. Mean motor nerve conduction velocity (MNCV) along distal and proximal segments: median, 61.2 (±9.1) (W-E) and 57.8 (±13.2) (E-Ax) meters per second; ulnar, 63.7 (±9.1) (W-E) and 50.6 (±10.0) meters per second. Mean sensory nerve conduction velocity (SNCV): median, 34.7 (±6.7) (F-W), 63.7 (±7.1) (W-E) and 62.8 (±12.3) (E-Ax) meters per second; ulnar, 38.0 (±6.7) (F-W), 63.4 (±7.5) (W-E) and 57.0 (±10.1) (E-Ax) meters per second; radial, 45.3 (±6.8) (F-W) and 64.2 (±11.0) (W-E) meters per second; sural nerve, 43.4 (±6.1) meters per second. The amplitudes of action potential and H-reflex were also standardized. Mean H latency was 28.4 (±3.2) milliseconds. And, the fundamental principles, several factors altering the rate of nerve conduction and clinical application of nerve stimulation techniques were reviewed.

Abstract PDF: The clinical picture and CSF findings in cryptococcal meningitis may be identical with those of tuberculous meningitis. The differential diagnosis can be made by finding the budding yeast organism in the counting chamber of in stained smear, the detection of cryptococcal antigen in CSF by the latex agglutination test, and by culture of the fungus on Sabouraud agar. We experienced a case of cryptococcal meningitis in the 48 years old woman, which was confirmed by Indian ink preparation and culture.
