The circulating endothelial cells(CEC).tumor necrosis factor(TNF)

Glycemia and Lacticemia of 39 children with pneumonia were assayed. Levels of TNF - and CEC count from the patients with respiratory failure(1.45± 0.18μg/l

11.50 ±1.41 × 106/l) were higher than those of children with pneumonia (0.97±0.25

7.05 ±0.17

p<0.01)

but Lower than those of groups of Multiple Systems Organ Filure(MSOF) (2.23 ±0.39

19.14±2.53.P<0.01). TNF- x was obviously related to CEC count (r=0.796

p<0.05). Glycemia and Lacticemia from patients with respiratory failure were almost similar to those of patients with MSOF were obviously increased (11.82±3.34

7.69 ±0.84mmol/1

P<0.001) lt suggested that TNF - x may be involved in the prognoses of respiratory failure and the damages of vessel endothelial cells (VEC) may he a key factor

when pneumonitis exists and TNF - x and CEC count are colsely related to the emergency scores.degrees of illness and organ dysfunctions.
