FIG. 4.

Phosphorus changes after Ad.hPTH administration to PTX rats. Ad.hPTH (10¹¹ VP per gland) was infused into both parotid glands of PTX rats (n = 8 per group) and blood was collected 2 days after vector infusion. Urine was collected from the bladder after sacrifice. There was a trend (p = 0.07) toward lower phosphorus concentrations in the serum of rats after treatment with Ad.hPTH (A). The urinary phosphorus-to-creatinine ratio was significantly elevated (*p = 0.028; 124% increase) in Ad.hPTH-treated rats compared with saline-treated controls (B).
