Foamy liver is seen in: (AIIMS Nov 2013)
(Putrefaction- produced mainly by the action of bacterial enzymes (lecithinase- Cl.Welchii), anaerobic organism (from bowels), causing marked hemolysis & liquefaction in blood vessels & tissue spaces, thus producing following effects-
a. Colour changes- Greenish discolouration in Rt. iliac fossa, marbled appearance.
b. Foul-smelling gases- CO2 + NH3 + CH4 + mercaptans (non-inflammable) + H2S (inflammable), gas bubbles cause crepitation, sponge-feeling, blood-stained froth from mouth & nostrils, distension of body, anus and uterus prolapse, P.M. blisters, face distorted, nail, skull sutures & hair loose, skin shows slippage, comes off in glove & stocking fashion, post-mortem luminescence (due to Photobacterium fischeri bacteria and Armillaria mellea fungi).
c. Liquefaction of tissues (Colliquative putrefaction), Skeletonisation, Honey-comb appearance of liver/ Foamy liver.)
