The effects of the sodium channel toxins saxitoxin, veratridine, deltamethrin and Anemonia sulcata toxin II on the spontaneous contractile activity of cultured rat skeletal muscle cells, were investigated. In addition, the influence of the external concentrations of K+ and Ca2+ ions was studied. The results indicate that the spontaneous contractility of cultured muscle cells is a suitable endpoint for assessing subtle alterations in the electrical properties of excitable membranes, and for quantifying in vitro the potency of neurotoxicants acting on the excitable membranes of nerve and muscle cells.

Diabetes mellitus is the most common endocrine disorder. The plant Syzygium cumini has been used in traditional medicine for the treatment of diabetes. The present study investigated the effect of ethanol extract of S. cumini seeds on uptake of glucose by L-6 rat skeletal muscle cells. S. cumini seeds were extracted with varying solvents and quantitative phytochemical analysis was carried out, ethanol extract of seeds exhibited higher content of tested phytochemicals. The effect of different concentrations (300µg/ml – 1000µg/ml) of ethanol extract of seeds were studied on glucose uptake activity of L-6 rat skeletal muscle cells. It was observed that with the increase in concentration, the glucose uptake activity was also increased. The results of the study supports and demonstrates the antidiabetic potential of ethanol seed extracts of Syzygium cumini utilizing in vitro model. KEY WORDS: Diabetes mellitus, Syzygium cumini, phytochemicals, glucose uptake, L-6 cells
