Control of Human Exposure Experiments -: conjunctival stain test to the damage (Continued)
Separate the upper and lower eye pupil,[link widoczny dla zalogowanych], told his subjects about the direction of rotation to the upper and lower eye,[link widoczny dla zalogowanych], observed with an ophthalmoscope,[link widoczny dla zalogowanych], the red area is the degeneration or necrosis of a conjunctival epithelial record the results a percentage of key indicators,[link widoczny dla zalogowanych], referred to as Statistical Methods SigmaPlot3.0 1.4 software statistical functions,[link widoczny dla zalogowanych], matched to their control of the f test. 2 Experimental results shown in Table 1 Table 1 before exposure, followed by conjunctival damage spot area test results () Note t · paired l test, P <001, Ying significant difference. 3 Discussion 3. l potential indicators in this preliminary study, It has the objective, the advantages of simple operation is beyond the sensitivity of our original estimate. We estimated in the original design: because, as an objective indicator may not be very sensitive, so only arranged at the highest exposure group, measurement, measurement of the experiment in the first period ? (low-dose exposure group: formaldehyde 2.21mg / m), by the pre-experiment, two subjects showed a significant positive response, which realized the potential of this indicator. Suggest that in future studies to strengthen the research and application of the indicators. 3.2 The selection of dyes according to variety
