In vivo effect of interleukin-1beta and interleukin-1RA on oocyte cytoplasmic maturation, ovulation, and early embryonic development in the mare

Table 2 Number of punctured follicles, percentage of recovered cumulus-oocyte complexes, and percentage of degenerated, immature, metaphase I and metaphase II oocytes in each group.

		COCs	Oocytes
	Number of injected-punctured follicles	Percent of recovery	Percent of DEG	Percent of immature	Resumption of meiosis
PBS i.f., CEG i.v.	23	91 (21/23)^a	19 (4/21)	0 (0/21)	81 (17/21)^a
IL-1β i.f., saline i.v.	25	80 (20/25)^a	20 (4/20)	20 (4/20)	60 (12/20)^ab
PBS i.f., saline i.v.	15	73 (11/15)^a	27 (3/11)	27 (3/11)	45 (5/11)^b

PBS, Phosphate buffer saline; CEG, crude equine gonadotropin; IL-1β, interleukin 1 beta; i.f., intrafollicular; i.v., intravenous; DEG, degenerated; MI metaphase I; MII, metaphase II. a and b are significantly different (P < 0.05).
