[Application of NIR spectroscopy technology in the field of insect pests detection].

Near infrared spectroscopy (NIRS) is the most rapidly developing and the most noticeable spectrographic technique in the 80's (the last century). Its principle in detection of insect pests was introduced. The applications of NIRS to the field of insect pests detection were mainly summarized.

[A component of earthworm fibrinolytic enzyme having higher thrombolytic activity than total components in vivo].

Aim: To select higher thrombolytic and lower toxic single component of earthworm fibrinolytic enzymes (EFE).

Methods: EFE containing total components were obtained by affinity chromatography from Eisenia fetida. Using ion-exchange chromatography to separate three main components EfP-0-2, EfP-I-1 and EfP-I-2 from EFE, their thrombolytic activity and toxicity were compared with EFE.
