Actinidic archaea and viroids related hepato-gastrointestinal
syndrome.INTRODUCTION Endomyocardial fibrosis (EMF) along with
the root wilt disease of coconut is endemic to Kerala with its
radioactive actinide actinide Any of the series of 15
consecutive chemical elements in the periodic table from
actinium to lawrencium (atomic numbers 89–103). All are
radioactive heavy metals; and only the first four (actinium,
thorium, protactinium, and uranium) occur in nature in beach
sands. Actinides like cerium cerium (sēr`ēəm) [from the asteroid
Ceres], metallic chemical element; symbol Ce; at. no. 58; at.

valence +3 or +4. producing intracellular magnesium deficiency
due to cerium-magnesium exchange sites in the cell membrane has
been implicated in the etiology of EMF . Endogenous digoxin
digoxin: see digitalis. , a steroidal glycoside which functions
as a membrane sodium-potassium ATPase inhibitor has also been
related to its etiology due to the intracell
