摘要: Abstract 1. The effect of starvation on the metabolism gut glutamine and ketone-bodies peak lactating, non-lactating virgin rats was investigated. 2. arterial blood ketone-body concentration increased by ∼ 7-, 6- 13-fold in 48 h-starved virgin, lactating rats, respectively. 3. decreased 32% (p 4. maximal activity phosphate-dependent glutaminase or small intestine fed peak-lactating 5. Portal drained viscera flow 25% rats. 6. Arteriovenous difference measurements for across showed an increase net uptake 10-, 17- 29-fold 7. Glutamine extracted at a rate 487 nmol/100 g body wt. which greater 33% 8. It is concluded that, although accompanied diminished rates gut, such decreases were partially compensated bloodflow extraction ketone-bodies.
