As an experimental model of human
tonsillitis
, Arthus
tonsillitis
of the rabbit was produced. In a previous paper, we demonstrated that an increased fibrinolytic activity in the circulating blood and increased proteolytic activity of the local tissue with Arthus
tonsillitis
were observed. In the present study, the mechanism of the increased proteolytic activity at the local site (tonsil with Arthus-type
tonsillitis
) was examined using cell cultures of lymphocytes originating from the tonsil with Arthus-type inflammation. That is, lymphocytes isolated from tonsil tissue of the rabbit were cultured in a culture medium for the short term. After culture, the used medium was collected and the presence of plasminogen activator in the culture medium and lymphocytes was investigated. It was clarified that plasminogen activator did exist in the culture medium of lymphocytes originating from the tonsil of rabbits with Arthus
tonsillitis
. Furthermore, addition of
T cell growth factor
to the culture medium of lymphocytes derived from non-treated tonsil induced the development of plasminogen activator in that culture medium. However, addition of B cell growth factor did not lead to the development of plasminogen activator activity in the culture medium. These results suggest that plasminogen activator originating from lymphocytes of the tonsil may play an important role in the increased proteolytic activity observed at the local site of Arthus
tonsillitis
.

No significant differences were found between hyperplastic
tonsillitis
and recurrent tonsillitis in the intensity of cell-mediated immune response of tonsillar T cells, the ratio of T cell subsets, the ratio of Tac-positive cells, and the stimulation index determined after incubation in the presence of
TCGF
alone. However, the proportion of the cells in phase S+G2+M, the ratio of OKT9-positive cells to total tonsillar lymphocytes, and the amount of polyamines (especially putrescine) were greater in hypertrophied tonsils than in the tonsils with recurrent tonsillitis. Some characteristics of recurrent tonsillitis are discussed from these differences. Comparison of tonsillar lymphocytes from children vs. adults produced similar results. The proportion of cells in phase S+G2+M, the ratio of OKT9, and the amount of polyamines were greater in tonsils of children. In addition, differences in the function of tonsillar and peripheral lymphocytes from the patient are also discussed.
