title: [Effects of different extracts from Radix isatidis on lymphocytes of mice by biothermodynamics].
abstract: OBJECTIVE
  To observe the different extracts from Radix Isatidis on multiplication of mice lymphocytes.
  
  
  METHODS
  Lymphocytes were separated and cultured. Immunological activities of different extracts from Radix Isatidis were studied by thermodynamics and the results were tested by the conventional pharmacological experiments.
  
  
  RESULTS
  The results showed that the water extract and residue had significant immunological effects while organic solvent extracts had immunological activity to some extent.
  
  
  CONCLUSIONS
  The comparison of immunological activity among the extracts from Radix Isatidis were as follows: residue after extracting > general extract > nBuOH extract > EtOAc extract > CHCl3 extract > P E extract.
