This article reports the effects of lead on the DNA and RNA content of rat liver and kidney. Experimental use of 125 male rats of the same age, body weight 195.2 ± 10.8g, divided into 14 groups. Groups 1 to 3 were control groups, 15 in total, and were determined on days 1, 20 and 45 respectively. Groups 4 to 10 were given Pb (CH 3 COO) 2 · 3 H 2 O 20 mg / kg daily for 1, 3, 5, 10, 20, 30 and 45 days. Group 11 was given lead acetate 20 mg / kg daily for 40 days. Lead acetate was given 40 mg / kg daily on days 41-45. Group 12 was given daily Lead acetate 40mg / kg, for 5 consecutive days; Group 13 in
