Two cases of hyaline-droplets degeneration in the liver of male and female rainbow trout were obtained in the Trout Culture Experimental Station at Samegai, Shiga Prefecture. Both the cases were proved to be of pathological nature, one being, so to speak, ejective type and the other non-ej ?? tive type. The present report deals with the former.
Infected by a Monococcus, liver of the trout is troubled with a infectious disease resembling “furunculosis” and shows heavy degeneration of its tissue. Results of its examination by using several dyes are tabulated in the accompanying diagram. In entire liver, ?? ells are filled with droplets with various sizes which are rather variable in the rea ?? tion to dyes and different from those observed in higher vertebrates in nature of staining or others. On account of neoplastication of the droplets, cell outlines become indistinct and hepatic cell cords show a syncytial appearance. Droplets ejected from cells flow into blood vessels or invade superficial masses of colloidal substance. Stainability of the latter appears to vary in accord with the length of time elapsed since first ejection of droplets.
It appears to me, therfore, appropriate to diagnose the present case as “acute hepatitis with hyaline-droplets degeneration”.
