Alterations in the Corpuscles of Stannius of Euphorbia royleana Treated Catfish, Heteropneustes fossilis

Background: We aimed to evaluate effect of Euphorbia royleana exposure on histocytology of corpuscles of Stannius in fish, Heteropneustes fossilis. Methods: Fish were subjected to 2.47 mg/L and 0.618 mg/L of E. royleana for short-term and long-term exposure, respectively. Blood samples were collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, and 28 d in long-term experiment a...

Hypocalcin from Stannius corpuscles inhibits gill calcium uptake in trout.

Bidirectional whole body flux and branchial Ca2+ influx were measured in freshwater rainbow trout. Intra-arterial injections of homogenates of Stannius corpuscles (CS) as well as of a 54-kDa isolated product (hypocalcin) exerted an inhibitory effect on whole body Ca2+ influx, but did not effect Ca2+ efflux. Hypocalcin was more effective in reducing Ca2+ influx in trout acclimated to low-calcium...

Identification of hypocalcin (teleocalcin) isolated from trout Stannius corpuscles.

We have isolated and purified a glycoprotein from the corpuscles of Stannius (CS) of trout, which we consider hypocalcin (also called teleocalcin), the major hypocalcemic hormone of fish. This product is present in relatively large amounts in the CS of several species (i.e., European eel, tilapia, goldfish, and carp). Hypocalcin is typically released from the CS in response to an experimentally...
