Abstract
To define the pattern of serum and gastric lactic dehydrogenase (LDH) in Nigerians. Levels of this glycolytic enzyme were estimated in 60 (49M, 20F) healthy Nigerians using the spectrophotometric techniques. The mean serum LDH levels were 181.2 ±43.9 i.u./L and 157.05 ±37.82 i.u./L in males and females respectively. The difference related to sex was significant (P>0.05). The mean gastric juice LDH levels in males and females were 17.39 ±7.94 i.u./L and 15.75 ±7.50 i.u./L. There was no correlation between the serum and gastric juice LDH levels. The levels in the healthy Nigerians are comparable to the observed values in the Caucasians.
