Allium cepa root meristem cells in mitomic dividing stage. (a) Normal cells in telophase mitomic dividing stage. (b and c) Abnormal dividing cells in cyclophosphamide (10 mg/ml) treated group showing multipolarity and sticky chromosome. (d) Normal as well as few abnormal dividing cells in n-Butanol fraction of Tinospora cordifolia (NBTC) (10 mg/ml) treated root showing sticky and vagrant chromosome. (e) NBTC (15 mg/ml) treated showing most of the cells in prophase indicating arresting of growth. (f) NBTC 5 mg/ml and cyclophosphamide 10 mg/ml treated showing multipolarity, vagrant, fragmented and sticky chromosome. (g) NBTC 10 mg/ml and cyclophosphamide 10 mg/ml treated meristem showing normal mitotic dividing stage prophase and telophase. (h and i) NBTC 15 mg/ml and cyclophosphamide 10 mg/ml treated root showing many cells in prophase indicating arresting of growth along with few swelled and deformed cells (×100)
