The effects of methylmercury compounds on the skin (in vitro) of the leopard frog (Rana pipiens)
Comparative and General Pharmacology, 1973Abstract 1. 1. Leopard frogs readily survive injections of large amounts of dimethylmercury or methylmercuric chloride. 2. 2. The short-circuit current and P.D. across the skin ( in vitro ) were not changed by dimethylmercury (10 −3 M ) but were reduced by methylmercuric chloride (10 −4 M ).

AbstractThe effects of the environmental contaminants methylmercury (MeHg) and inorganic mercury (HgCl2) on cell viability, intracellular calcium concentration ([Ca2+]i), and reactive oxygen species (ROS) generation were studied in rat cerebellar granule neuron cultures using fluorescent methods. MeHg exhibited an LC50 (2.47 μM) tenfold lower than that

The effects of natural methylmercury compounds on regeneration of photoreceptor organs were studied in three freshwater planarians: Polycelis tenuis, Dugesia lugubris, and D. tigrina. Accumulation of methyl mercury in the planarian body suppressed regeneration of P.

Abstract Methylmercury (CH3Hg(II)) was measured in various tissues and whole body of sheepshead minnows, Cyprinodon variegatus, following exposure to 100 ng/L methylmercury chloride (CH3HgCl) alone or in combination with one of the organic compounds cysteine (CH3Hg-Cys), thiourea (CH3Hg-Thu), or thioglycolate (CH3Hg-Thg).

A good quality control/quality assurance programme should be implemented in all environmental or health related studies on mercury and its organic compounds, particularly, for monomethylmercury (MeHg) which is the most toxic mercury compound. This can be achieved initially by analysing suitable certified reference materials (CRMs), which are available ...
