A comparative investigation of the activity of superoxide dismutase in patients with leukoplakia and healthy controls.

Context And Aim: Oral leukoplakia has recently been re-defined as "a predominantly white lesion of the oral mucosa that cannot be characterised as any other definable lesion". Superoxide dismutase (SOD) is one of the enzymatic anti-oxidants which form the first line of defence in the cell. There are very limited data available on the analysis of SOD in leukoplakia patients.

Amelioration of Doxorubicin-Induced Cardiac and Renal Toxicity by Oxycarotenoid Lutein and Its Mechanism of Action.

We set out to determine the effect of oxycarotenoid lutein on reducing cardiac and renal toxicity induced by doxorubicin (DXR). We started with oral administration in rats of lutein for 15 d before administering DXR (30 mg/kg body weight, intraperitoneally, in a single dose). Animals in all groups were sacrificed 24 h after DXR administration.

Amino acids in sandal (Santalum album L) with special reference to cis-4-hydroxy-l-proline and sym. homospermidine.

Sandal (Santalum album L) contains several interesting amino acids and amines which are not seen in other plants. This includes cis-4-hydroxy-l-proline in free form in leaves, flowers and seeds while trans-4-hydroxy-l-proline in bound form. Traces of 3, 4 dehydroproline is also detected in sandal leaves.
