[The effect of stimulation of toss simulated at sea on shock in severe burn rabbits].
OBJECTIVE
To investigate the effect of stimulation of toss simulated at sea on shock in severe burn rabbits.


METHODS
One hundred and thirty-two rabbits were randomly divided into normal control group (NC group, n = 6), toss group (T group, with treatment of continuous toss, n = 42), burn group (B group, with treatment of burn, n = 42), burn and toss (BT group, with treatment of continuous toss after burn, n = 42). The level of Cr, BUN, HCT and LA from blood samples in T, BT, B groups were observed at 2, 6, 8, 12, 24, 36, 48 post treatment hour (PTH). The changes in urinary volume was measured during 48 PTH. The histopathologic changes in kidney were observed at above-mentioned time points. The above indices in NC group were also observed.


RESULTS
The mean urinary volume in B group during the first and second 24 PTH was (2.59 +/- 0.23) and (2.86 +/- 0.29) mL/h, while that in BT group was (1.61 +/- 0.13) and (1.66 +/- 0.16) mL/h respectively, which were all lower than those in NC group (6.06 +/- 0.18 mL/h, P < 0.01). The levels of HCT and LA in BT group were obviously higher than those in B group at each time point. The levels of Cr and BUN in BT group at 24, 36, 48 PTH were significantly higher than those in B group. The histopathological observation showed the capillary vessels and mesenchymal cells of kidney glomerulus were congestive, epithelial cells in kidney tubules were swollen. The infiltration degree of inflammatory cells in kidney tubule, and the pathological changes of erythrocyte cast in BT group were more serious than those in B group.


CONCLUSIONS
The toss simulated at sea can significantly aggravate shock and the renal damages in severe burn rabbits.
