Many anorectal opearations may result in damage to anal sphincter function and,as a result,patients have problems when they are defecating.Measuring anal sphincter function not only benefit for operating,but also may help prevent operating complications and do good for rehabilitation.Therefor,measuring anal sphincter function is important.This article will review those measures about anal sphincter function.

OBJECTIVETo find an inhibitor to reduce the volatilization of formalin.
METHODThe saturated solution of sodium hydrosulphite (SHS) was sprayed on the surface of the anatomy specimens, then the concentration of formaldehyde in the air was tested.
RESULTSThe concentration of formaldehyde in the air of SHS sprayed group [(3.10 +/- 1.22) mg/m3] was significantly lower than that of the control group [(8.36 +/- 4.11) mg/m3, P < 0.01].
CONCLUSIONSHS may be a volatilization inhibitor for formalin, which could reduce the concentration of formaldehyde in the air.
