Effects of 11‐day treatment (12‐day study) with M‐PTH/PTHrP or alfacalcidol on serum calcium (sCa) in thyroparathyroidectomized (TPTX) rats. TPTX rats were treated for 11 days with daily s.c. injection of either vehicle or M‐PTH/PTHrP, or with daily oral alfacalcidol at the indicated doses, and sham‐surgery control rats were s.c. injected daily with vehicle. The levels of Ca in serum and urine were assessed. Blood samples were collected from the jugular vein at 8 hours (A) and at 24 hours (B) after the last treatment administration, and assessed for total sCa. Total urine was collected in metabolic cages over the time intervals of 0 to 8 hours (C), and 8 to 24 hours (D) and assessed for total urinary Ca. Data are means ± SEM; n = 6 or 5 (2.0 and 4.0 nmol/kg of M‐PTH/PTHrP); *p < 0.05 M‐PTH/PTHrP versus TPTX‐vehicle; #p < 0.05 TPTX vehicle versus sham.
