Haemodynamic changes in the cerebral circulation of the cat during occlusion of the middle cerebral artery

In a group of 21 cats, the middle cerebral artery pressure (MCAP) was recorded by means of a catheter introduced into the artery at its origin, just distal to the occlusion. The effects of hypertension, hypercapnia, and hypocapnia were studied. In a group of five cats, both middle cerebral arteries (MCA) were catheterized and the pressure was...

Induction of cytochrome formation and stimulation of oxidative dissimilation by hemin in Streptococcus lactis and Leuconostoc mesenteroides

Aerobic glucose dissimilation of washed cells of Streptococcus lactis grown in peptone-glucose-yeast extract medium is characterized by the formation of large amounts of lactic acid, a small amount of acetic acid, and traces of acetoin: a corresponding amount of oxygen is taken up. Aerobic metabolism by washed cells of S. lactis and Leuconostoc...
