Although there have been many reports about the importance of the spleen's role in
hepatic fibrogenesis, the exact mechanism is still uncertain. The author designed this
study to evaluate splenic function on hepatic fibrogenesis.
The degree of hepatic fibrosis and the population of splenocyte subsets were studied in
the experimental animal model with fibrosis produced by injecting normal swine serum
intraperitoneally into Sprague-Dawley rats. The animals were divided into three groups;
group A was subjected to injection of swine serum only, group B swine serum and
complete Freund's adjuvant, and group C swine serum and cyclosporin A. The
experimental hepatic fibrogenesis by swine serum was augumented by coinjection with
the adjuvant and inhibited by cyclosporin A.
The study of the splenocyte subset revealed increased percentages of splenic B cell and
CD4+ cell and a decreased percentage of CD8+ cell, and these changes of splenocyte
subset were also augumented by the adjuvant and inhibited by cyclosporin A. The
percent of monocytes was not significantly altered, although a tendancy of early
decrease by the adjuvant was noted.
