✓ The role of the aging human erythrocyte in the mechanisms leading to cerebral
vasospasm after subarachnoid hemorrhage was investigated using an in vitro model for the …

✓ The short-term (≤ 72-hour) reaction to subarachnoid injections of various blood
components was determined in a canine model of cerebral vasospasm. Platelet-rich plasma …

✓ The cause of cerebral vasospasm has been generally attributed to the vasoconstrictive
substances released from platelets. The role of extravasated erythrocytes in vasospasm has …

✓ Contractile activity of the various fractions of fresh and incubated blood was studied in
vitro using the isolated canine basilar artery. Of the various fractions of fresh blood …

Erythrocytes are not present in normal cerebrospinal fluid (CSF), and their presence there
implies subarachnoid hemorrhage. The differential diagnosis of subarachnoid hemorrhage …

In an effort to determine which blood elements play a critical role in the development of
cerebral vasospasm, adult cats were subjected to prepontine injection of either autogenous …

The in vivo spasmogenic activity of various blood components was examined in dogs. Each
blood fraction was injected into the cisterna magna at 0.5 or 1.0 ml/kg body weight, after the …

✓ Partially purified protein from washed and artificially hemolyzed erythrocytes, known to
cause significant contractions of isolated canine cerebral vessels in vitro, was injected into …

✓ The release of intracellular products from lysed blood cells is believed to play a critical
role in the etiology of vascular pathology following intracerebral hemorrhage. The present …

Studies of the cerebrospinal fluid (CSF) can be complicated by abnormal amounts of protein
products gaining access to the fluid through subarachnoid hemorrhage. Since the CSF may …
