The Hypoactivity Associated with the Repeated Exposure to Atrazine Is Related to Decreases in the Specific Binding to D1-DA Receptors in the Striatum of Rats

Table 1

Rats body weight before, during, and after ATR exposure (percent of initial weight).

	Vehicle	ATR 100 mg/kg
Injection 1	100 (17)	100 (17)
Injection 2	96.77 ± 0.23 (17)	96.32 ± 0.38 (17)
Injection 3	91.58 ± 0.41 (17)	92.65 ± 0.74 (17)
Injection 4	89.42 ± 0.61 (17)	90.54 ± 0.63 (17)
Injection 5	90.22 ± 0.55 (17)	91.71 ± 0.54 (17)
Injection 6	90.41 ± 0.81 (17)	92.01 ± 0.73 (17)
Injection saline	89.32 ± 0.85 (17)	90.87 ± 0.93 (17)
2 months after ATR	116.65 ± 0.72 (5)	116.53 ± 2.18 (5)

Values are mean ± SEM of percent of basal weight (before ATR or vehicle treatment); mean initial weight values (g) for vehicle and ATR , respectively, were and ; mean initial weight values (g) for vehicle and ATR , respectively, were and .
