1 Objective To investigate the relationships of gelatinase A and gelatinase B expressions with clinicopathological feature and prognosis of laryngeal squamous cancer.

2 Conclusion Gelatinase A may play an important role in the progression of primary hepatocellular carcinoma.

3 Total RNA was isolated and gelatinase A (MMP2) gene expression level were measured by reverse transcription polymerase chain reaction (RT-PCR).

4 Inhibiting activities of compounds on gelatinase (MMP-2) were measured by using succinylated gelatin as substrate.

5 Immunohistochemical method and zymogram analysis method, etc. were adopted to observe the change of microvessel structure,[] gelatinase and its inhibitor expression.

6 The changes of levels of MMP-2, TIMP-2 mRNA and protein lead to, in part, changes of gelatinase activity within the posterior fibrous sclera.

7 OBJECTIVE: To explain the biological features and accommodations of gelatinase and its role in corneal angiogenesis.

8 These epiphytic bacterial strains were screened for enzymatic and antibiotic bioactivity. Several prospective strains having antibiotic or amylase or gelatinase or lipase activity were found.

9 Results The extract of Oratosquilla could inhibit the secretion and activity of Gelatinase B in CNE-2Z by dose-response fashion.

10 Supernatant liquid of SPC-A-1 cells pretreated with thalidomide groups was collected and the activity of gelatinase was measured by Zymgraphy.

11 Objective To investigate the effect of HCMV infection on the activity of gelatinase in cultured human embryo lung fibroblast( HEL ).
