Anticataract effects of oral magnesium taurate in rat model of galactose-induced cataract / Nur Adilah Awaludin

Cataract, a condition characterized by loss of visual acuity, results from loss of lens transparency due to the denaturation of lens proteins, crystalline. magnesium deficiency coupled with increased intracellular calcium activates calpain, a protease that denatures crystalline. Dysfunction of membr...
