Figure 1: Polymorphonuclear leukocyte (PMNL) counts of the mammary secretions from rbIL-8-infused (solid line) and saline-infused (broken line) glands are shown in (a) and (b), respectively, and those of the mammary secretions obtained from the untreated glands during the drying-off period are shown in (c). Cows A–D and E–H were given 50 μg and 10 μg of rbIL-8, respectively. (+) or (−) in the upper part of each figure denotes the presence or absence of clots in the mammary secretions, respectively. As the PMNL counts were obtained after removing milk clots containing PMNL, the PMNL counts for the mammary secretions with milk clots were not accurate. PMNL counts of more than 108 cells/mL were not counted.
