DIFFERENT EFFECTS OF hGH AND bGH ON ELECTRON TRANSPORT COMPONENTS OF LIVER MITOCHONDRIA

Mitochondrial (mito) protein synthesis has been shown to be influenced by hypophysectomy (Hy) and GH treatment (JBC 248 4263:1973). Cytochromes a, a₃, b, c, C₁ and flavin have now been measured by difference spec...

IMMUNOELECTROPHORETIC STUDIES OF RAT SOMATOMEDIN

Serum was collected from hypophysectomized rat (HyR) 30 min. after an I.V. injection of hGH. The serum was used to prepare an antiserum (AS) in a rabbit. AS was adsorbed with lyophilized HyR serum (5 mg/ml) an...

Correlation of blood gas, lactate, and illness in newborn

We hypothesized that “true” blood lactate (LA) is an index of respiratory need superior to PaO₂, PaCO₂, or pH. Our thesis required a simple, rapid, sensitive LA test. We used a new automated, enzymatic 2-waveleng...

EFFECT OF INCREASED OXYGEN-HEMOGLOBIN AFFINITY ON CARDIAC TISSUE OXYGEN UNLOADING OF LAMBS FOLLOWING INHALATION OF CARBON MONOXIDE (CO)

Previous studies in newborn lambs have shown that a decrease in whole blood oxygen affinity results in an increased coronary sinus PO₂ and in an decreased cardiac output for the same oxygen consumption (V_O2). The...
