  • Title: Antibody-containing cell response in lymph of sheep after intra-intestinal infusion of ovalbumin with and without DEAE-dextran.
    Author: Beh KJ.
    Journal: Immunology; 1979 May; 37(1):279-86. PubMed ID: 572818.
    Abstract:
    The output of antibody-containing cells (ACC) was monitored in efferent ileal lymph after continuous infusion of ovalbumin into the ileum of sheep with and without the adjuvant DEAE-dextran. When ovalbumin was infused at the slow rate of 5 ml/h, maximum outputs of 2.9 x 10(5) and 2.4 x 10(5 ACC/h were observed on days 9 and 16 respectively. When infused at the faster rate of 15 ml/h, peak levels of 6.9 x 10(5) and 11.7 x 10(5) ACC/h were recorded on days 10 and 16 respectively. The maximum response was substantially enhanced when ovalbumin was infused simultaneously with DEAE-dextran when a mean output of 51.7 x 10(5) ACC/h occurred on day 10. With all treatments the distribution of ACC amongst various immunoglobulin classes was similar. During the first few days of the response IgM-specific ACC predominated and later IgG1-specific ACC were most abundant. Throughout the response a substantial proportion (10-81%) of ACC in efferent ileal lymph were IgA-specific.
