Fundus perimetry is the device that provides visualization of the fundus and the precise localization of the stimuli on it. With the increasing importance of the direct fundus perimetry for certain focal retinal morphologic abnormalities, the scanning laser ophthalmoscope[SLO]has been utilized as a system to eliminate some of the classic technical problems in fundus perimetry. The aim of this study was to evaluate the normal light sensitivity values for microperimetryusing SLO system. Thirty eyes of thirty normal subjects were examined in 60 degrees image field using stimuli of variable intensity. The maximal retinal distance point which responded to stimulus was recorded, point which responded to stimulus was recorded, and the distance[millimeter]from the fovea was calculated by the Bennett formula. The maximum distance from the fovea at the given stimulus intensity was measured as follows :0.7596 +/-0.5262millimeter at 28decibel, 2.2050 +/-0.5878millimeter at 26decibel, 3.0571 +/-0.7151millimeter at 24decibel, 4.3690 +/-1.0973millimeter at 22decibel, and 5.6557 +/-1.3458millimeter at 20decibel. In conclusion, we were able to establish the normal range of light sensitivity in Microperimery examination. It may serve as the baseline for subsequent study of retinal pathology and functional evaluation as well as its treatment.

PURPOSE: The CD5 molecules are pan-T cell antigens and are found on a minor subpopulation of B cells. CD5 antigens are involed in an intracellular signal transduction as well as in an intercellular signal transduction between CDS+ T cell/CD72+ B cell by CD5/CD72 interaction. CD5 antigens are known to be participated in classic immune reactions and in this study CDS mRNA expressions by lymphocytes were examined in allergic patients controls, acute febrile infectious disease controls and normal controls to elucidate the possibility of CDS involvement in allergic immune reactions. METHODS: Fifteen allergic patients, ten patients of acute febrile infectious disease patients and ten normal controls were studied. Venous blood was drawn and mononuclear cells were separated. T cells and B cells were separated using immunomagnetic beads. Total RNA was extracted and RT-PCR (reverse transcriptase - polymerase chain reaction) was done to detect CDS antigen mRNA expression. RESULTS: 1) CDS mRNA overexpressions were detected in allergic patient controls as compared to that in acute febrile infectious controls. CDS mRNA was not detected in normal controls. Semiquantitative CD5 mRNA expressions were measured as relative expressions of CD5 to GAPDH. Relative quantities of CD5 mRNA expressions were 90.656.24% in allergic patient controls and 23.76+3.58% in acute febrile infectious patients. CONCLUSIONS: CDS mRNA overexpression is a characteristic phenomenon in allergic immune reactions. From these result, CD5/CD72 pathway might be the preference immune mechanism in allergic immune reaction and the further study for the exact mechanism of CDS involvement in allergic immune reactions may be necessary

The writers performed Sbarbaro type total hip replacement arthroplasty on two cases with degenerative arthriris of both hips complicated by avascular necrosis of the femoral head. In each case, the procedure was carried out on the worse hip, while in one case a standard femoral head prosthesis was inserted to the less severely involved hip. The Sbarbaro type prosthesis consists of a modified Austin Moore head component and an acetabular cup with tynes that fix the metal to the acetabulum and does not require the use of cement. The initial results in both cases, evaluated by the method of D'Aubigne and Postel, are as follows; Grade 5 for pain(pain both slight or intermittent), Grade 5 for motion(very good or 161 to 210 degrees), and Grade 5 for ability to walk(very good; no cane or crutch but a slight limp).

Sacro-iliac joint is, as other joints, the prediIection site of tuberculous or pyogenic arthritis as well as primary or metastatic tumor. The writers reviewed twenty cases of sacro-iliac lesion performed at the Department of Orthopedic Surgery, Seoul National University Hospital, for the period of five years from June 1972 till May 1977. 1. They are tuberculous arthritis eleven, pyogenic arthritis five, ankylosing spondylitis two(one associated with spinal stenosis, the other with hip invoIvement), osteosarcomatosis one, metastatic tumor from adenocnrcinoma of prostate one 2. Infection is the predominant Iesion in sacro-iliac joint, and tuberculous arthritis is twice than pyogenic arthritis. 2. Early diagnosis of sacro-iliac lesion is difficult, but S-I stress test is a valuable finding. 4. Two of eleven cases of tuberculous arthritis, two of five cases of pyogenic arthritis with mild involvement were treated conservatively without sequele, but in more advanced cases, surgical intervention was preformed.

We clinically reviewed four patients who were suffering from aseptic meningitis combined with polio-like paralysis and performed radiological. neurological and virological studies on them. Three patients were admitted to the department of Pediatrics. Asan Medical Center from March to August 1990, and one patient was admitted to the department of Pediatrics. Kangnam General Hospital. The results were as follows; 1) During the period of study, 18 patients (10.1%)out of 178 aseptic meningitis patients also suffered from hand, foot and mouth disease, and three patients (1.69%) out of 178 patients also suffered from polio-like paralysis. 2) The age of the patients who also suffered from polio-like paralysis were eight months, 22 months, 23 months and four years old respectively. Three patients were male and one patient was female. 3) Paralysis developed three to five days after aseptic meningitis infection. 4) In two cases, Magnetic Resonance Imaging (MR) showed two small cavitary lesions that means anterior horn cell necrosis in concordant with residual paralysis. Axial T1-weighted image showed decreased signal intensity and axial T2-weighted image showed increased signal intensity. In another case 20 days after onset of illness MR was performed, the transverse myelitis showed mild swelling of cornus medullaris. Follow up MR in 2 months revealed atropic change in lower thoracic spinal cord. 5) The electromyography and nerve conduction velocity test revealed acute polyradiculoneuropathy. 6) Serologic virus study were carried out in three cases for Coxsackievirus A16 and Enterovirus 71. The Enterovirus 71 antibody titer were 1:128 in two cases and 1:64 in one case. The Coxsackievirus A16 antibody titer were less than 1:4. This study showed that the causative agents for polio-like paralysis during this period seemed to be the Enterovirus 71 infection.

Recently, cases with typical clinical manifestations of infectious mononucleosis are increasing in Korea. So, to evaluate the recent epidemiology of EBV infection in Korea, we performed EBV serologic antibody tests for IgG antibody to EBV-viral capsid antigen (VCA) and antibody to EBV-associated nuclear antigen (EBNA) among the 108 healthy Korean infants and children whose ages were from newborn to 15 years old. And the results were as follows; 1) The positive rates of anti-VCA IgG 100% in newborn, 90% in 2 to 6 months, 20% in 7 to 12 months, 60% in 1 to 2 years, 77.3% in 3 to 4 years, 88.5% in 5 to 6 years, 90% in 7 to 9 years, and 100% in 10 to 15 years of age, respectively. 2) The anti-VCA IgG titers ranged from 1:20 to 1:1280. 3) The positive rates of anti-EBNA were 100% in newborn, 60% in 2 6 months, 10% in 7 to 12 months, 60% in 1 to 2 years, 68.2% in 3 to 4 years, 84.5% in 5 to 6 years, 70% in 7 to 9 years, and 100% in 10 to 15 years of age, respectively. 4) The anti-EBNA titers ranged from 1:2 to 1:128. According to these data, the age of primary infection of EBV has increased compared to the previous data in Korean children.

Although severe hemolytic diseases of the newborn triggered by anti-M are very rare, anti-M alloantibodies have been known to be associated with a cause of multipie intrauterine death. Serological and hematological investigations have been reported on a woman who experienced four multiple intrauterine deaths due to anti-M. The mothers blood type was of group A, NN and the husbands cells were of group B, MN. In the serological examination at 9th week's gestation of the fifth pregnancy, anti-M antibodies were identified in her serum. The antibodies comprised IgM saline agglutinin at a titer of 16 at 4 degrees C and IgG agglutinin reacted in an indirect antiglobulin technique at a titer of 4 at 37 degrees C. She underwent high-dose immunoglobulin infusion therapy on a monthly program from 3rd month gestation and a total of 6 times of intravenous immunoglobulin was given. The anti-M titer did not rise during the pregnancy. She delivered a live girl by cesarean section at the 37th week because of a failure of induction. The childs blood type was of group O, MN. The child was discharged and developed normally.

The purpose of this study was to evaluate the effectiveness of topically applied capsaicin cream for the treatment of chronic low back and posterior neck pain. Fourty-one patients with chronic low back or posterior neck pain of more than 6 months despite comprehensive management in our rehabilitation department were selected for this study. Of these subjects, a group of 21 patients used capsaicin cream, and the other 21 patients used NSAID gel as a control group. Pain intensities in both groups were measured with the visual analogue scale(VAS) before the treatment, 2 weeks and 5 weeks after the treatment. McGill Pain Questionnaire(MPQ) was used before and 5 weeks after the treatment. According to followed-up VAS, MPQ-number of words chosen, and MPQ-pain rating index, there was an evidence of effective pain relief by capsaicin cream for the low back and posterior neck pain 5 weeks after the treatment. We conclude that continuous use of capsaicin cream for 5 weeks can be beneficial for the chronic pain patients in relieving pain and subsequently helping their rehabilitation process.

We reviewed the clinical findings of infectious mononucleosis and performed Epstein-Barr virus (EBV) serologic antibody tests in infectious mononucleosis and healthy group. One groupwas 18 cases of children, diagnosed as infectious mononucleosis who had been admitted to the department of Pediatrics, Asan Medical Center for two years and eight months, from November, 1989 to June, 1992. Another group was 20 cases of healthy 5-year old children. @ES The results wereas follows: 1) The age distributions of 18 patients with infectious mononucleosis were as follows: nine patients were less than 5 year old and nine patients (50%)were older than 5 year old. 2) The hematologic findings revealed increased atypicallymphocytes in sixteen patients (88%), leukopenia in one patient (6%), thrombocytopenia in one patient (6%). In addition, we observed transient hepatitis in eight patients (44%) and jaundice in one patient (6%). 3) Hemophagocytic sydrome wasdeveloped in one patient who expired due to meningitis. 4) The heterophil antibody tests werepositive in two cases (11%) out of eighteen infectious mononucleosis patients. 5) EBV serologic antibody tests for IgM antibody to EBV-viral capsid antigen (VCA) in 18 patients were all positive, which implies primary infection. 6) EBV serologic antibody tests for IgG antibody to EBV-VCA and antibody to Epstein-Barr nuclear antigen (EBNA) in helathy 5-year old children were negative in 3 cases (15%) out of 20 cases each other, which suggests primary infection might occur afer five years of age. 7) Recently, more cases of clinically typical infectious mononucleosis are detected and the onset of EBV primary infection is becoming late in Korea, which is thought to be due to economic developments and improvements of environmental hygine. And we recommend EBV serologic antibody test for the confirmative diagnostic test of infectious mononucleosis.

It is well known that small dose of belladonna alkaloid(atropine, scopolarnine) has the effect of decreasing the heart rate in normal conscious subjects, but the mechanism involved in it remains still unanswered. Based on various lines of evidence, the most likely mechanism seems to be the blockade of sympathetic ganglion caused by the alkaloids and it is possible that the effect on the slower heart rate may differ in the depressed state of the sympathetic ganglion when under halothane anesthesia. The present study was undertaken, therefore, on comatose patients and halothane anesthetized patients with and without atropine premedication about 1 hour before anesthesia to observe the effect of a small dose of scopolamine(0.1 mg) which affects the heart rate more significantly than atropine in conscious subjects. The results were as follows: 1) In the comatose patients, scopolamine(0.1 mg) produced a significant decrease in heart rate. 2) During halothane anesthesia without atropine premedication, scopolamine produced a slight decrease in heart rate. 3) During halothane anesthesia with atropine premedication, scopolamine produced a significant increase in the heart rate. These results indicate that scopolamine can further affect the sympathetic ganglion already depressed by halothane, and it is suggested that scopolamine is more effective in blocking the sympathetic ganglion than halothane.
