title: [The levels of angiotensin and aldosterone in gases of hyperthyroid Graves' disease with and without hypokalemic periodic paralysis].
abstract: OBJECTIVE
  To investigate the relationships between the changes of plasma angiotensin I (AT I). Angiotensin II (AT II). serum aldosterone (Ald) levels and hypokalemic periodic paralysis (THPP) complicating hyperthyroid Graves' disease.
  
  
  METHODS
  The levels of serum potassium, TT3, TT4, FT3, FT4, Ald and the plasma AT I, AT II and 24 hours urine potassium output were determined in 73 cases of hyperthroid Graves' disease, of which 43 were complicated by THPP and the other 30 were grouped as NTHPP cases.
  
  
  RESULTS
  The mean level of serum potassium in THPP group was significantly lower than that in NTHPP group (P = 0.000), and the mean level of 24 hours urine potassium output in THPP group was significantly higher than that in NTHPP group(P = 0.000); The mean levels of plasma AT II and serum Ald in THPP group in upright position were significantly higher than those in NTHPP group (P = 0.008 and 0.013, respectively). The mean levels of 24 hours urine potassium output, plasma AT II and serum Ald in upright position were negatively correlated to serum potassium in both groups. The level of serum Ald in upright position was positively correlated to the level of 24 hours urine potassium out-put. The mean levels of plasma AT I and AT II in supine position were positively correlated to serum T3, and the level of plasma AT II in upright position was positively correlated to serum FT3.
  
  
  CONCLUSIONS
  The level of 24 hours urine potassium output rises in THPP patients; the high levels of AT and Ald may contribute to the pathogenesis of the disease.
