[Dynamics of blood circulation and oxygen consumption in mammary glands].
In lactating albino mice, the blood flow rate and oxygen consumption in mammary tissues varied with a period of 45--50 min. The maximal values were reached at the initial stage of the secretory cycle: oxygen consumption 9.7 +/- 2.5 ml O2/100 g.min, and blood flow 94.3 +/- 21.2 ml/100 g.min. The minimal values of oxygen consumption and blood flow ere recorded on the 30--35th min of the secretory cycle and were 1.2 +/- 0.4 ml O2/100 g.min and 16.2 +/- 5.3 ml/100 g.min, respectively. Oxygen consumption by the secretory cells at the beginning of the secretory cycle averaged 19.3 +/- 5.2 ml 92/100 g.min, and within 30--35 min--3.3 +/- 1.1 ml O2/100 g.min. The linear relations between the intensity of blood flow and oxygen consumption in the mammary gland were revealed.
