        결핵성 뇌막염 진단에 있어서 뇌척수액 Adenosine Deaminase 활성도에 관한 연구

        N/A The prognosis of tuberculous meningitis is closely linked to the stage at which treatment is started. The cerebrospinal fluid findings, however, are often ambiguous, It has been suggested by recent investigations that ADA activities in cerebrospinal fluid may help differentiate tuberculous meningitis from aseptic meningitis. In this study, cerebrospinal fluid adenosine deaminase activities were measured in 23 cases of tuberculous meningitis, 9 cases of aseptic meningitis, 9 cases of purulent meningitis, 24 cases of miscellaneous neurologic conditions and 23 cases of normal controls. The results obtained were as follows: 1) The mean ADA activity in tuberculous meningitis was 17.39±10,34 U/L, in bacterial meningitis 7.87±8.52 U/L, in aseptic meningitis 2.83±1.92U/L, in miscellaneous neurologic conditions 2.80±5.61U/L and in control 1,09±0.51U/L. 2) The ADA activitiies in tuberculous meningitis showed significantly higher values than in other groups (P<0.001), 3) Cerebrospinal fluid ADA activities differentiated tuberculous meningitis from those with aseptic meningitis being higher than 4.5U/L in all and higher than 6.5U/L in 96% case of tuberculous meningitis, but lower than 6,5U/L in aseptic meningitis and less than 3.5U/L in normal controls. 4) In tuberculous meningitis, ADA activities showed significant correlation with protein in cerebrospinal fluid (P<0.01), but in other groups, no significant correlation with available routine parameters in cerebrospinal fluid. It is suggested that measurement of ADA activity in cerebrospinal fluid is a available test which is relatively easily performed for diagnosis of tuberculous meningitis, especially differential diagnosis with aseptic meningitis.

        There has been a need for animal experimental models to study the peripheral nerves to evalute the peripheral neuropathy. However, electrophysiologic test methods to confirm peripheral neuropathy in small experimental animals has mot been properly addressed due to technical difficulties and also the limitation of numbers of examinations due to the invasive natures of previous techniques of peripheral nerve conduction studies in experimental animals. The purpose of this experiment is to find out easy, reliable and noninvasive repeatable technical of nerve conduction study of peripheral nerves of rat. The electrophysiologic tests including motor and sensory nerve conduction studies were performed in both hind limbs of 64 rats. And the results were reported with detailed description of techniques. The mean value(±SD) of motor nerve conduction velocity was 41.8±3.0m/sec and that of the sendory nerve conduction velocity was 29.7±1.7m/sec and they showed stable results. In addition to its accuracy, this technique is a relatively simple and nonivasive repeatable methods of nerve conduction study of rat. But the amplitudes of compound muscle action potential(CMAP) and compound nerve action potential(CNAP) revealed wide ranges of variability.
