RESUMO
Anticataract activity of Ambroxol, Spirulina and Vitamin E was examined using the naphthalene cataract model. Adult female albino rats of Wistar strain weighing between 180 and 220 grams were taken and divided into eight groups. Group I received light liquid paraffin 5 ml/kg/ day p.o. for 6 weeks. Group II received naphthalene solution 0.5 gm/kg/ day p.o. for first three days and 1 gm/kg/day p.o. thereafter for six weeks. Group III received Ambroxol suspension in 0.5% carboxy methyl cellulose (CMC) at the dose of 100 mg/kg/day p.o. alongwith naphthalene. Group IV received Spirulina in distilled water at the dose of 1500 mg/kg/ day p.o. alongwith naphthalene. Group V received Vitamin E emulsion at the dose of 50 mg/kg/day p.o. alongwith naphthalene. Group VI received Ambroxol alone at the dose of 100 mg/kg/day p.o. Group VII received Spirulina alone at the dose of 1500 mg/kg/day p.o. Group VIII received vitamin E alone at the dose of 50 mg/kg/day p.o. Lens glutathione, soluble protein and water content profiles revealed the preventive role of Ambroxol, Spirulina and Vitamin E in naphthalene-induced cataract in female rats.
