BACKGROUND Reocclusion of recanalized coronary arteries often limits the efficacy of coronary thrombolytic therapy in patients with acute myocardial infarction. Activated protein C (APC) is an important regulatory enzyme in hemostasis. In view of the potential of human APC as an anticoagulant and profibrinolytic agent, the effect of APC on thrombolysis with(More)
Changes in tetrodotoxin (TTX) content of the puffer fish Takifugu rubripes during seed production were examined. Two mature female puffer fish T. rubripes (samples 1 and 2) that contained TTX were used. The toxic eggs were artificially fertilized, and hatchlings were reared in an indoor tank for 50 days and then in a netcage at sea for an additional 48 or(More)
The effects of rearing temperature (23–29 °C) during the larval and juvenile stage on survival, growth and skeletal malformations in the seven-band grouper Epinephelus septemfasciatus were investigated. The survival rate of juveniles 30–40 mm in total length emerging from eggs was higher at 25 and 26 °C (0.1–1.3 %) than at 23 °C or 27–29 °C (0.004–1.5 %).(More)
The distributions and recoveries of the hemolytic activities and quantities of protein of complement components during cold ethanol fractionation were studied. Most of the components were recovered in Cohn's fraction III, with slight activities in fractions I and IV. The hemolytic activities of C1 and C5 were recovered in high yields in fraction III. The(More)
Serum depleted of the first component of complement (C1D) was prepared by treating fresh human serum with Sepharose-IgG in the presence of triethylenetetramine-N,N,N',N'',N''',N'''-hexa-acetic acid and di-isopropyl fluorophosphate at acidic pH (5.2). The total hemolytic activity of this C1D could be increased to approximately 75% of that of the original(More)
