19382722 Zhao JQ, Wen YF, Bhadauria M, Nirala SK, Sharma A, Shrivastava S, Shukla S, Agrawal OP, Mathur R: Protective effects of propolis on inorganic mercury induced oxidative stress in mice. Indian J Exp Biol. 2009 Apr;47(4):264-9.

Exposure to mercuric chloride (HgCl2; 5 mg/kg; ip) induced oxidative stress by increasing lipid peroxidation and oxidized glutathione level along with concomitant decrease in glutathione and various antioxidant enzymes.
Release of serum transaminases, alkaline phosphatase, lactate dehydrogenase and y-glutamyl transpeptidase were significantly restored towards control after propolis treatment.

Mercuric chloride (HgCl2) is an industrial agent with toxic effects on the immune system, kidney, lung, and nervous tissue, but little is known about its effect on bone.
MT immunization plus HgCl2 treatment dramatically decreased bone mineral density (BMD), and the humoral bone formation indices, alkaline phosphatase (ALP) activity and osteocalcin.

Guinea pigs were given a single intraperitoneal injection of 1.35 mg/kg body weight of mercuric chloride; then various kidney enzymes and extracellular DNA were assayed in urine.
Sequential collection of urines allowed for kinetic studies: membrane markers alkaline phosphatase and gamma-glutamyltransferase were first released, then cytosolic lactate dehydrogenase and mitochondrial glutamate dehydrogenase, finally extracellular DNA; DNA release is equated with cell death.
