[Changes in hemoglobin content, erythrocyte count and hematocrit in nickel deficiency].
In a total of four different studies, two of them involving two generations, the essentiality of nickel could be shown by reduced growth in response to a diet with 15 ppb nickel. In 30-day-old self-reared rats, anemia was induced in the Ni-deficient animals despite a high iron supply of 50 mg iron per kg diet. In the F1 generation of the Ni-deficient animals, the erythrocyte count had fallen by 36%, the hematocrit by 37%, and the Hb content by 44%. In the F2 generation in which the animals were given 100 ppm iron, surpassing their requirement three times, the blood parameters of the deficient animals were reduced by 8-10%. At the age of 50 days of the F1 generation the erythrocyte count had fallen 23% compared to the values of the control group, the hematocrit 14%, and the Hb content (16%) from 12.7 to 10.7 g/100 ml blood. An influence on the protein content of the serum and on the catalase activity of the erythrocytes was not observed and only at times was there an influence on the urea content of serum.
