Table 4. Analysis of AEF activity in peripheral blood monocytes isolated from mice with AA amyloid induced by monocytes isolated from mice with AEF-induced AA amyloid.

Donor mice		Recipient mice
Mouse	Amyloid grade	Group	No. of mice with amyloid/total no. of mice	Amyloid grade
H2-1	1+	J1	2/3	1+–2+
H2-2	3+	J2	3/3	1+
H2-3	2+	J3	2/3	1+
H2-4	1+	J4	3/3	1+–2+
H2-5	2+	J5	2/3	2+

Mice in group J received an i.v. injection of monocytes isolated from H2 (1–5) and a sequential s.c. injection of 0.2 ml 1% silver nitrate day 1, 7 and 14 and were sacrificed day 16.The presence of amyloid was analyzed in spleen after Congo red staining.
