Glutamine synthesis and utilization were studied in the plantaris muscle after removal of its functional synergists, the soleus and gastrocnemius muscles. Rat plantaris muscle was compared with unoperated controls at 7, 14, and 30 days after synergist ablation and induction of hypertrophy. Glutamine
Cobalt, a metal with numerous industrial applications, has been associated with lung disease, an extreme form of which is an interstitial fibrosis. The biochemical mechanisms underlying this toxicity are not understood. In vitro studies have suggested that cobalt(II) ions are able to generate
The D-xylose absorption test was applied to clinically normal horses and to horses with signs of gastrointestinal disease. A dosage of 0.5 grams of xylose per kilogram of bodyweight was useful in detecting horses that absorbed the pentose abnormally. The clinical findings were correlated with gross
To learn whether surface force changes precede the appearance of lung edema during experimental intoxication due to paraquat, we studied rats for 1 day following injection of 27 mg/kg iv. By 24 h, surface-active material recovered by lung lavage was decreased 32 percent, and changes in lung
Placental growth factor (PlGF or PGF) is a member of the VEGF (vascular endothelial growth factor) family. It plays a pathological role in inflammation, vascular permeability, and pathological angiogenesis. The molecular signaling by which PlGF mediates its effects in non-proliferative diabetic
Lung metabolism on exposure to hyperbaric oxygen was studied in rat lungs perfused with artificial media and ventilated with O2 at 0.2, 1, or 5 ATA. During the first 80 min of exposure to O2 at 5 ATA, glucose utilization increased 55%, lactate plus pyruvate production increased 45%, total CO2
Recently there has been a great deal of interest in exploring possible ways to protect the lung from oxidant damage. Since sulfhydryl compounds are among the most important endogenous antioxidants, their therapeutic use has been proposed. Glutathione (GSH), the main intracellular nonprotein
