KININ-FORMING AND DESTROYING ACTIVITIES OF SALIVA

Kinin-Forming Enzyme of Rat Cardiac Tissue

We have previously reported the presence of a cardiac kinin-generating enzyme (CKGE) in human cardiac tissue. The present study was undertaken to examine the subcellular localization and the biochemical properties of this system in rat cardiac tissue. Cardiac bomogenate (20 mg) was incubated with beattreated plasma substrate and citrate-pbospbate buffer (pH 5.3) in the presence of peptidase inh...

The presence of bradykinin-like polypeptides, kinin-releasing and destroying activity in brain.

In the previous report1),in which the presence in the bovine nerve granules of ZETLER'S Fa-peptide2)was reported,a resemblance to bradykinin,of this gut-stimulating polypeptide,was suggested.Since the discovery of bradykinin formation by the action of snake venom and trypsin(RocHA E SILVA et al.3)and of kallidin by kallikrein(WERLE et al .4)),formation of vasodilator and smooth muscle stimulati...

Destroying Civilization, Destroying Nature

the effects of cooperative versus individual directed reading thinking activities on students inferential and referential questions

two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...

The First Component of the Kinin-forming System in Human and Rabbit Plasma

The isolation and characterization of the first component of the kinin-forming system in human and rabbit plasma are presented. Functionally, the molecule is the precursor of the activator of prekallikrein (Pre-PKA) and evidence is presented that it is identical with Hageman factor (clotting factor XII). The component from each plasma possessed similar characteristics. This molecule was found t...
