In vivo assessment of antidiabetic and antioxidant activities of rosemary (Rosmarinus officinalis) in alloxan-diabetic rabbits.

Rosemary (Rosmarinus officinalis), used in traditional Turkish folk medicine for the treatment of hyperglycaemia, is widely accepted as one of the medicinal herb with the highest antioxidant activity. Accordingly, the present study was designed to investigate the possible actions of ethanolic extract of the leaves of Rosmarinus officinalis on glucose homeostasis and antioxidant defense in rabbits. In the first set of experiments, hypoglycaemic effects of oral administration of various doses (50, 100 and 200 mg/kg) of the extract were examined in normoglycaemic and glucose-hyperglycaemic rabbits.

Effect of linear alkylbenzene sulphonate (LAS) on non-specific defence mechanisms in rainbow trout (Oncorhynchus mykiss).

Linear alkylbenzene sulphonate (LAS) is among the most widely disseminated xenobiotics to enter waste streams and the aquatic environment. In the present investigation, we present a novel approach to evaluate in toxicity of LAS. The effects of sublethal levels (0.
