A fibrinolytic metalloprotease has been purified from the fruiting bodies of the edible honey mushroom (Armillariella mellea). The enzyme has a molecular weight of 18538.1508, as measured by MALDI-TOF mass spectrometry and includes Zn2+ ion as found by ICP/MS. The N-terminal amino acid sequence, XXYNGXTXSRQTTLV, do not match any known protein or open reading frame. It hydrolyzes fibrinogen as well as fibrin, but does not show any proteolytic activity for other blood proteins such as thrombin, human albumin, bovine albumin, human IgG, hemoglobin, or urokinase. This protease hydrolyzes both A alpha and B beta subunits of human fibrinogen with equal efficiency. The enzyme activity was strongly inhibited by EDTA and 1,10-phenanthroline, indicating that the enzyme is a metalloprotease. No inhibition was found with PMSF, E-64, pepstatin, and 2-mercaptoethanol. The activity of the purified enzyme was slightly increased by Mg2+, Zn2+, and Co2+, but the enzyme was totally inhibited by Hg2+. It has broad substrate specificity for synthetic peptides, and a pH optimum at 7, suggested that the purified enzyme was a neutral protease. It was thermally stable up to 60 degrees C and the maximum fibrinolytic activity was at 55 degrees C.

This study was designed to monitor secondary insults and their impact on outcomes of patients with hypertensive basal ganglia hemorrhage (HBGH). One hundred and twelve patients with HBGH (male 73, female 39) of age 42 +/- 8 years (range from 38 to 57 years) were studied. Operations included craniotomy or trephination drainage with urokinase thrombolysis. Conventional therapies were also given to the patients including the administration of mannitol, crystalloid and colloid solution. In the meantime, blood pressure (MAP), temperature (T) and SaO2 and other parameters were recorded in the intensive care unit. The ICP values were recorded, and the early clinical outcome was assessed upon discharge according to Glasgow Outcome Scale. Cerebral Perfusion Pressure was calculated as CPP = MAP-MICP. Outcomes in the group without secondary insults were better than that in the group with secondary insults (P < 0.01). No unfavorable outcomes were found in the 59 cases managed by ultra-early surgery whereas 36.1% of the cases operated after 6 hours of onset had unfavorable outcomes. It is concluded that the high incident rate of secondary insults in HICH patients influences outcome. Ultra-early surgery may also contribute to improved quality of survival.
