Sections of the mammary glands from lactating rats 14-20 weeks old treated with saline, extract, dopamine + extract, and metoclopramide. (A) Mammary gland from lactating rat receiving 0.9 % NaCl, showing little alveolar development and the abundance of mammary adipose cells. (B) Mammary gland from lactating rat receiving 1600 mg.kg−1 extract, showing ducts branching into ductile, with well defined alveolar development (compared to A,C and D) and fewer adipose cells. (C) Mammary gland from lactating rat receiving metoclopramide 5 mg.kg−1, showing little alveolar development and the abundance of adipose cells. (D) Mammary gland from lactating rat receiving dopamine 5 µg.kg−1+ extract 100mg.kg−1, showing little alveolar development and fewer adipose cells. (E) Mammary gland from lactating rat receiving dopamine 5 µg.kg−1, showing little alveolar development and very little adipose cells Magnification A-E x 4. Adp, adipose cells; Bv, blood vessel; Avc, alveolar cells, Dc, ductile.
