Examples of non-toxic

• Quantitative model demonstrating that recombinant adeno-associated virus and green fluorescent protein are non-toxic to the rat retina.

• A non-toxic, nonadsorptive conservative bulk fluid dye was used to capture images of flow channels in the biofilm/porous media matrix.

• The measurements of the radiolabelled agents are extremely precise, even at very low concentrations, thus small non-toxic amounts of the compound can be given.

• It was mentioned above that conventional liposomes act as non-toxic vesicles for an insoluble drug, releasing it slowly back to the circulation.

• In the normal situation oestrogens (and mono-hydroxy bile acids) are conjugated with sulphate (non-toxic polar compounds) or glucuronide (hepatotoxic and cholestatic compounds) in the liver.

• The positions of individual eggs were recorded by marking the adjacent leaf surface with a fine tipped, non-toxic pilot felt pen.

• These include patients operated on for acute appendicitis, acute cholecystitis, hernia or non-toxic goitre.

• Doses should not be adjusted in fit-free, non-toxic patients simply to bring the levels into the 'therapeutic range'.
