Table 4. Rate (%) of EMA-positive cells ± SD in both the epithelium and lamina propria of a region of HSV1-negative and of a region of HSV1-positive cells (virus plaque) at 0, 12, 24 and 36 h post inoculation (pi).

	% EMA-positive cells at … h pi
	0	12	24	36
HSV1-negative epithelium	0.4±0.1	0.3±0.2	0.4±0.2	0.3±0.2
HSV1-negative lamina propria	0.4±0.3	0.7±0.5	0.5±0.5	0.3±0.1
HSV1-positive epithelium	ND	0.8±1.4	1.2±0.3*	1.0±0.6
HSV1-positive lamina propria	ND	ND	0.1±0.2	0.5±0.5

ND = not determined; no HSV1-positive cells were found.

* Significant differences compared with the control (HSV1-negative tissue) at the 0.05 level.
