Heparin Activity

SummaryPreparations were made of rabbit liver globulin by the method of Jaques for heparinase and their effect on heparin studied. The results confirmed the observations of a progressive loss of anticoagulant activity with globulin in 0.9% saline, of a loss of metachromatic activity after phenol extraction and the reversal of the latter by alkali. The latter observations were due to the solubility in phenol of heparin on combination with protein. With suitable preparations, a decrease in anticoagulant activity without decrease in metachromatic activity was observed, i.e. conversion of heparin to uroheparin. Loss of heparin due to combination with protein and resulting precipitation, solubility in phenol, etc. followed a protein pH-dissociation curve. Loss of heparin anticoagulant activity due to heparinase was maximal at pH 5.4. No loss of heparin occurred at pH values more acid than 5 or more alkaline than 7.

ABSTRACT The metabolism of oestrone, oestradiol-17α and oestradiol-17β has been studied in rabbit liver slices. Oestradiol-17α and oestradiol-17β were isolated as metabolites of oestrone. When oestradiol-17α17α was incubated oestrone and oestradiol-17β were formed, whereas oestradiol-17β gave rise to oestradiol-17α and oestrone. Quantitative experiments showed that after incubation of oestrone 5–8 times as much oestradiol-17β was found as oestradiol-17α.

Technical Details

A variety of acquisition methods for arterial spin labeling (ASL) perfusion MRI exist, often with different names referring to broadly similar approaches. This chapter outlines the main flavors of ASL in common use, along with their strengths and weaknesses, before finally presenting the current consensus of the community on good acquisition parameters for general use. The chapter considers the choice of labeling (e.g. pseudo-continuous versus pulsed), readout (e.g. 2D versus 3D), the choice of post-label delay, and a number of other solutions to correct for artifacts such as arterial contamination. Avoiding extensive technical details, this chapter seeks to inform the ASL user when making choices about acquisition parameters for the use of ASL and also provides enough terminology to help a new user understand the key parameters that they need to know when presented with a new ASL dataset.
