[Expression of water channel protein 1 in the lung of the drown rat].

OBJECTIVE

To determine the expression of water channel 1 protein in the lung of drown rat and that of after death thrown into the water.

METHODS

Immunohistochemical method was used and the computer image analysis was conducted to detect the distribution of AQP1.

RESULTS

The positive expression of AQP1 was seen in the capillary endotheliocyte of the interstitial and around bronchi and in the alveolar endothelial cells. The value of intergrated optical density was statistical significant.

CONCLUSION

It suggests that AQP1 is one of sensitive signs to distinguish ante-mortem and postmortem immersion.
