Table 1

Results of rat eye examinations by slit-lamp on day 17 postpartum; grades 0–3 depend on lens opacification degree.

Groups number	Groups	Grades
		Grade 0	Grade 1	Grade 2	Grade 3	%
Group 1	Normal saline	12	0	0	0	0
Group 2	A. officinalis (400 mg/kg)	12	0	0	0	0
Group 3	Sodium selenite	0	0	2	10	94.4
Group 4	Sodium selenite + A. officinalis (200 mg/kg)	0	4	5	3	63.8
Group 5	Sodium selenite + A. officinalis (400 mg/kg)	0	5	4	2	52.7

The percentage grade of each group is calculated based on the point value of each category. Grade% = ((total number of grade 0 × 0) + (total number of grade 1 × 1) + (total number of grade 2 × 2) + (total number of grade 3 × 3))/36 × 100.
