本文分析了151例颅内感染性疾病,其中病毒脑83例占54.9%,化脑38例占25.2%,结脑30例占19.9%。结脑血清钠、氯均明显低于病毒脑。化脑,结脑血清钙均低于正常值。化脑血尿素氮高于病毒脑和结脑且高于正常值。病毒脑,化脑,结脑脑脊液LDH之间差异均有显著意义,脑脊液CRP化脑和结脑与病毒脑之间差异有显著意义。 In this paper, 151 cases of intracranial infectious diseases were analyzed, including 83 cases of viral brain accounting for 54.9%, 38 cases of cerebral infarction accounting for 25.2% and 30 cases of tuberculous meningitis accounting for 19.9%. Cerebrospinal fluid sodium, chlorine were significantly lower than the virus brain. The brain, brain serum calcium were lower than normal. Cerebral blood urea nitrogen is higher than the virus brain and knot brain and higher than normal. There was significant difference between viral brain, cerebral and cerebrospinal fluid LDH, and there was significant difference between cerebrospinal fluid CRP-induced brain and tuberculous brain and viral brain.
