INTRODUCTION: It has been proposed that narcolepsy and REM sleep behavior disorder (RBD) have overlapped symptom profile and pathophysiology. This study was aimed at measuring and comparing changes in EEG frequency band of REM sleep in narcolepsy and RBD, applying EEG spectral analysis method. METHODS: Nine patients diagnosed as narcolepsy and the same number of RBD patients were studied. Spectral analysis of the REM sleep EEG was performed in each patient on 9 epochs selected evenly from the first, second, and third REM periods. Then, we compared frequency band percentages of REM sleep EEG in narcolepsy and RBD. RESULTS: Narcolepsy patients had significantly higher delta frequency ratio than RBD ones (p=0.00). In alpha and beta2 frequency bands, RBD patients showed higher percentage than narcolepsy ones. Slow wave sleep was more prevalent in narcolepsy patients. But, no difference of REM sleep percentage was found between the two groups (p=0.93). CONCLUSION: Higher delta frequency ratio in REM sleep of narcolepsy patients than RBD ones reflects that sleep-promoting mechanism is more dominant in narcolepsy than in RBD.

We are calling the erupting ground water as drug water or mineral water in Korea and thinking those water and food making water. Authors tried to investigate the evidence of contamination by user on the 10 erupting ground water and gained following results: 1. All of the mineral waters on 10 area in Seoul were unfittable to drinking water standard. 2. In the view of the bacteriology 80% were contaminated by coliform group. 3. The highest value of the free carbon dioxide contents were 652.96 ppm at Sam Sun Mineral Water.

In leprosy, it is generally believed that the defense against Mycobacterium leprae (M. leprae) is largely dependent on cell-mediated immunity (CMI) and there is an accumulating evidence that the patients with lepromatous leprosy have not only defective CMI specific for M. leprae, but also have generalized impairment of CMI. In contrast, the humoral immune reactivity, both specific and nonspecific, have been found to be normal or slightly increased. Recently, several investigators have enumerated the peripheral blood T and B lympocytes in patients with leprosy; however, there is no agreement as to the results. Furthermore, leprosy has been found to differ in its clinicai manifestations and immunological behaviors in different geographic areas and races. Nevertheless, there is yet no report in Korea concerning the T and B lymphocyte enumeration. The authors considered it is necessary to enumerate the peripheral blood T and B lymphocytes in Korean patients with leprosy to evaluate the immune status and the differences in the immunologic reactivity between the lepromatous and the tuberculoid spectrum of leprosy.

Recent studies indicated that cellular and humoral immune reactions against Afycobacterium leprae may be involved in the development of some of the pathological manifestations. In lepromatous leprosy one might anticipate the formation of immune complexes from concomitant occurrence of large amounts of mycobacteria and corresponding antibodies. Indeed, there are some evidences of an involvement of immune complexes in the pathogenesis of erythema nodosum leprosum(ENL), mainly based on clinical and pathological studies. Some of numerous immune cornplex tests have been applied for the study of leprosy, But no single test has yet been shown to be the rnost sensitive and the most specific for the entire spectrum of circulating immune complexes. Furthermore. Leprosy has been found to differ in its clinical manifestations and immunological behaviors in different geographic areas and races. The authors considered it is necessary to determine the circulating immune complexes in Korean patients with leprosy to evaluate the immune status and the differences in the immunologic reactivity between the lepromatous and the tuberculoid spectrum of Ieprosy.

Normal lymphocyte transfer (NLT) test is composed of two peaks of delaycd. hypersensitivity reaction of erythema and/or induration developed at the site of intradermal inoculatioa of allogenic lymphocyte. It has been suggested that NLT test is a px.siblc homograft raaction, how var tlv exact mecha.nism is remained to be resolved. In leprosy, there has been accumulating evidenc. indicating defective cell mediated. immunity detected by varioua immunological tests. The present study was undertaken to evaluate the immune capability of patients with leprosy using NLT test. A total of 20 hea,lthy volunteers, 20 lepromatous and 22 tuberculoid leprosy patients who were under antileprosy chemotherapy with DDS for varying periods, entered this study. Lymphocytes from hepatitis associati antigen (HAA) negative donor were isolated with Ficoll- Hypaque density gradient method and the cell concentration was adjusted by normal saline so as to give 2, 5 million cells per 0. 1 ml. Each recipient was given 0. 1 ml lymphocyte suspension on the flexor surface of th right forearm intrad.ermally using 1 ml tuberculi n syringe with a 26 gauge needle. The appearance and the size of induration was checked daily for 2 weeks. In this atudy, the NLT reaction pattem was classified as follows: a. normal pattem showing the first peak and second peak of reaction. b. first peak only showing the first peak, but no second peak, of reaction. c. flat pattem showing neitger the first peak nor the second peak of reaction The results were as follows: 1. There were normal pattem in sixteen persons(80%) and first peak only in 4 persons(20%) among twenty healthy human volunteers. 2. There were normal pattem in four patients(20%), first peak only in six patients(30%) and flat pattem in ten patients(50%) among twenty letromatous leprosy patients. 3. There were normal pattem in twelve patients(54.5%), first peak only in eight patients(36.4%) and flat pattem in two patients(9.1%) among twenty-two tuberouloid leprosy patients. These findings suggest that NLT test may be useful in evaluating the immune capability in leprosy and host factor in belived to be important in the development of both first and second peaks of NLT test.
