CAT = catalase, GST = glutathione- S-transferase, GSH = reduced glutathione, GR = glutathione reductase, TBARS = total thiobarbituric acid reactive species, FRAP = ferric reducing antioxidant power assay, eye = eye + the associated infraorbital sinus, CNS = central nervous system, gonads = ovaries or testes, n = 20.
The antioxidant parameters were assayed in tissues (heart, eye and the associated infraorbital sinus, central nervous system, lungs, kidney, spleen, liver, ovaries and testes) and plasma samples were collected at the time of autopsy and kept at -80°C until use.
Specimens of heart, eye and the associated infraorbital sinus, central nervous system, lungs, kidney, spleen, liver and gonads (ovaries and testes) were collected and placed in 10% buffered formalin during autopsy, and were treated using a routine histological technique and embedded in paraffin.
Glutathione-S-transferase was elevated in the eye and the associated infraorbital sinus and kidney, and decreased in the liver.
Glutathione-S-transferase activity was elevated in the eye and the associated infraorbital sinus and kidneys, and decreased in the liver.
While catalase showed significantly lower activity in the heart, lungs, liver and gonads of Mycoplasma-infected birds, glutathione-S-transferase was elevated in the eye and the associated infraorbital sinus and kidney, and decreased in the liver.
Instead of raising a leery eye, the associate retrieved a manager who did some quick research and provided a full refund based on her complaint of "lack of comfort".
Nonetheless, because of the special protection of the eye associated with the ocular surface, drug bioavailability and subsequent therapeutic efficiency obtained with these conventional dosage forms are very low.
However, as we age, prooxidants overwhelm the antioxidant defences resulting in oxidative stress and damage to tissues of the eye associated with the development of ocular pathologies such as corneal opacities, cataracts, and glaucoma.
A recently published case control interview study from Germany reported a significant four-fold increased risk of malignant melanoma of the eye associated with the use of radiofrequency (RF) transmitting devices, including mobile telephones (Stang et al, 2001).
Recently a four-fold increase in the risk of malignant melanoma of the eye was associated with the use of radiofrequency transmitting devices, including mobile phones in Germany.
