“…In contrast Fronek & Fronek (1970) and Vatner, Franklin & van Citters (1970) using implanted flowmeters found no changes in renal blood flow after meat. Increased renal blood flow would indicate dilatation of the renal arterioles as the mechanism producing increased creatinine clearances.…”

SUMMARY1. The exogenous creatinine clearance of conscious dogs has been measured by a method in which no loading doses of water or saline were given. The urine volume was thus in the normal range, 0-1-0 3 ml./min.2. Under these conditions, the exogenous creatinine clearance of fourteen dogs, measured 17 hr after a meal, was 2-74 ml./min kg- 4. Glycine (10 m-mole) by stomach tube caused increase in creatinine clearance of similar magnitude to that produced by meat. Creatine (50-150 m-mole) had no effect. 5. In discussion reasons are given for believing that the observed increase in exogenous creatinine clearance reflects an increase in glomerular filtration rate. Since this occurs with small doses of meat, increase in glomerular filtration may be important in normal renal function of dogs.

“…Postprandial EX has similarly reduced SBF compared to resting values (3,11,35), while some authors have reported no change (16,36). Additionally, postprandial EX has been found to produce higher heart rites and blood pressures compared to, fasting EX (12), while others have reported no differences (11,18). has been shown to profoundly effect the BF response to a meal (27,33,37).…”

“…Exercise has produced a diminution of gastric secretions (19) and eecreased SBF (2,3,4,21,24,25,28,30,31)', while others have found no change in SBF (11,16,32,34). Postprandial EX has similarly reduced SBF compared to resting values (3,11,35), while some authors have reported no change (16,36).

“…Several studies have reported that feeding increases splanchnic BF (SEF) at rest (7,11,16,26,27,29), with the increased BF correlated with the increased demands ff the digestive and absorptive processes (7). Exercise has produced a diminution of gastric secretions (19) and eecreased SBF (2,3,4,21,24,25,28,30,31)', while others have found no change in SBF (11,16,32,34). Postprandial EX has similarly reduced SBF compared to resting values (3,11,35), while some authors have reported no change (16,36).…”

“…Difficulties in the interpretation of splanchnic BF data have been further confounded by either incomplete (31,35) o0 omitted subject feeding information (1,2,4,9,24, 2R,32,34). others (3,4,5,9,11,16,21,23,24,25,34,35).…”
