چکیده

The spectrophotometric method of Schwert and Takenaka (11) for the assay of trypsinesterolytic activity hasbeen modified for the measurementof the trypsin inhibitor capacity of serum. An averagevalue of 0.99 mg. of trypsin inhibited per milliliter of serum (3 S.D. = ±0.30) wasdetermined for 50 control subjects. Patient serum assayvaluesdeterminedwith this method havebeenfoundsimilar to thosedetermined with the modified Kunitz method using l131-labeledcaseinas the substratein the normal range for a variety of pathologicconditionsand in the elevated range for abnormalities of the pancreas and generalized cancer conditions. From the standpointsof accuracy, simplicity, and speed this technic is believed to be an improvementover previousmethodsfor the measurementof this serum variable.

Human plasma and serum trypsin-like esterase activity.

A spectrophotometric method using benzoyl arginine ethyl ester (BAEE) is described for the assay of serum and plasma trypsin-like esterase activity. The method was used to find activities in serum and plasma (anticoagulated with oxalate and heparin) from 12 healthy males at 3 different reaction pH’s. The effects of calcium, oxalate, heparin, soybean trypsin inhibitor, ovomucoid, and heat on thi...

Automated measurement of protease-inhibitor capacity of serum, by use of chymotrypsin and casein.

Serum protease inhibitor activity was assessed from the ability of the serum to inhibit casein hydrolysis by ct-chymotrypsin (EC 3.4.4.5). Unmodified AutoAnalyzer equipment was used in conjunction with a fluorimetric method for dialyzable tyrosyl peptides. Serum, diluted with tris(hydroxymethyl) aminomethane buffer, was added to a chymotrypsin solution to inhibit its activity. For 72 sera, the ...

Crystalline Soybean Trypsin Inhibitor

A study has been made of the general properties of crystalline soybean trypsin inhibitor. The soy inhibitor is a stable protein of the globulin type of a molecular weight of about 24,000. Its isoelectric point is at pH 4.5. It inhibits the proteolytic action approximately of an equal weight of crystalline trypsin by combining with trypsin to form a stable compound. Chymotrypsin is only slightly...

بررسی تغییرات آلفا-1 – آنتی تریپسین (1 –AT) در سرم بیماران هیپوتیروئیدی

Alpha-1- Protease inhibitor or a1-Antitrypsin (a1-AT) is an a1-glycoprotein and a small molecule which acts as an extracellular inhibitor of serin proteases. It seems that this molecule protein has a protective role in tissues such as inhibition (inactivation) of elastase, colagenase, etc. a1-AT deficiency is a hereditary disorder which characteristed by reduced a1-AT serum level and may ...
