RESUMO
BACKGROUND: Radiation therapy is considered as an important tool in cancer treatment. Despite its impressive role in treating cancer, severe side effects in organs have been reported. To address these therapeutic side effects, several combination methods have been identified to minimize adverse effects caused by radiation therapy. AIMS AND OBJECTIVES: Based on higher radioactive sensitivity of testicular tissues, administration of Chlorophytum borivilianum (CB) Sant. F extracts was evaluated for its protective effects against radiation in testis. MATERIALS AND METHODS: Two forms of CB extracts (CB alone and CB-silver nanoparticles [AgNPs]) were administered at a dose of 50 mg/kg body weight in Swiss albino male mice for 7 consecutive days. Following 6 Gy gamma radiation, animals were observed for 30 days in four phases. Sperm counts, body weight, testicular weight and stereological and histological evaluation of testis were evaluated. RESULTS: Following irradiation, a significant decline in body weight (P = 0.008) and testicular weight (P = 0.001) was noted when compared with control. Ununiformed type A and B spermatogonia, partially filled tubules, inter-tubular vacuoles, and disrupted epithelium were the main types of damages caused by irradiation. Reorganization and resumption of histological features emerged from the 15th day postirradiation in CB extract (CBE)-treated animals. CONCLUSION: Testicular response was observed against radiation in animals treated with CB extracts, while CB-AgNPs indicated better toleration when compared to CB extract alone.
