Effect of polyoxyethylene and polyoxypropylene nonionic block copolymers on performance and recruitment of immune cell subsets in weaned pigs

Table 10 Numbers of CD45RA⁺naïve lymphoid cells in IFA and FA of the ileal PP of pigs treated at Day 0 with POE-POP after 5 weeks of the experiment

Treatment^a	Mean no.of CD45RA⁺cells^bin		Index of increase/decrease and % of increase of the mean no. ileal CD45RA⁺cells in^c
	IFA	FA	IFA	FA
Saline	85.80	504.80	1,00	1,00
POE-POP	173.60	784.00	+1.76	+1.55
Difference (POE-POP vs. Saline)	87.80*	279.20**	76%	55%

^aSingle p.o. application of 10 ml of either saline or POE-POP at Day 0; 5 pigs per group were euthanatized and sampled at Day 35 of the experiment. ^bNo. of the cells per μm² of randomly selected 12 microscopic fields (average area of digital image field was 71.168,87 μm²) in each of 5 serial sections of mid ileum per pig. ^cIncrease (+) or decrease (−) of the mean values in treated pigs vs. the mean values in control pigs (1.0 or 100%). Values differ significantly at *p < 0.05 or ** p < 0.01.
