Changes in serum protein lipid and electrolyte levels in rabbits at mid-altitude

1. The effects of mid-altitude on the profiles of total serum lipid, cholesterol, fibrinogen, albumin, Ca2+, Cl-, Na+ and K+ were investigated in rabbits for 22 days. From 30 rabbits living at sea level 15 were exposed to 1170 m and 15 to 2240 m altitude. 2. When compared with sea level values; total protein, albumin and K+ significantly decreased up to 5th day (P less than 0.01), then they gradually increased. 3. Total lipid, cholesterol, Ca2+, Cl- and Na+ levels elevated in 2nd day (P less than 0.01) then they gradually decreased to their sea-level values. 4. It was concluded that the adaptation mechanisms begin at mid-altitudes.
