Carcinoid-like tumours in the pseudobranch of Gadus morhua L.

Histology of pseudobranchial tumours in Atlantic cod(Gadus morhua) from the North Sea and the Baltic Sea

“…Double n u c l e a t e d "X-cells" and mitotic figures near fibrous septae occurred in several tumours especially in the small tnmours on gill filaments (Fig, 11). the Baltic Sea are identical to those earlier described for the Atlantic (Peyron & Thomas, 1929;Lange, 1973;Lange & Johannessen, 1977;Morrison et al, 1979;Egidius et al, 1981) as well as for the Pacific Stich et al, 1976;McCain et al 1976McCain et al 1979Wellings et al, 1977;Dawe, 1981). Most of these publications concentrate on the description of the common "X-cell" stage in pseudobranchial tumours.…”

The frequency, distribution, and pathology of three diseases of demersal fishes in the Bering Sea

“…These tumours can become large ( 6 x 3 cm) and are readily recognized. Similar tumours have been found in walleye pollock (Theragra chalcogrammas) (Takahashi, 1929), a fish common in Alaskan waters, and in Gadus morhua near Norway (Lange, 1973;Peyron & Thomas, 1929).…”

The potential role of the pseudobranch of molly fish (Poecilia sphenops) in immunity and cell regeneration

“…Roy et al 20 reported that in fish where the pseudobranch was removed, dark body coloration was assumed due to chromatophore expansion, and injections of pseudobranch extract led to the temporary paling of the body. Lange 21 suggested that serotonin could be produced in the pseudobranchial cells and transported to the brain via the choroid rete, where it may have affected the Corpus pineale , which is responsible for the melatonin synthesis. The absence of chloride cells in the pseudobranch of Molly fish provides good evidence that the PSCs can react to environmental salinity and have a role in osmoregulation.…”
