Imbalance of Th17/Tregs in rats with smoke inhalation-induced acute lung injury.

T helper (Th) 17 cells and CD4(+) CD25(+) regulatory T (Treg) cells are supposed to be critically involved in regulating autoimmune and inflammatory diseases. The aim of this study was to investigate the Th17/Treg pattern in rats with gunpowder smog-induced acute lung injury. Wistar rats were equally randomized to three groups: normal control group, ALI 6 h group (smoke inhalation for 6 h) and ALI 24 h group (smoke inhalation for 24 h).

Effects of a multivitamin/multimineral supplement on young males with physical overtraining: a placebo-controlled, randomized, double-blinded cross-over trial.

Objective: To investigate the effects of vitamin-mineral supplement on young males with physical overtraining.

Methods: Two hundred and forty male Chinese field artillery personnel who undertook large scale and endurance military training and were on ordinary Chinese diet were randomized to receive a multivitamin/multimineral supplement or a placebo for 1 week. After a 1-week wash-out period, a cross-over with 1 week course of a placebo or multivitamin/multimineral supplement was conducted.

A novel model of burn-blast combined injury and its phasic changes of blood coagulation in rats.

Burn-blast combined injury has a complex pathological process that may cause adverse complications and difficulties in treatment. This study aims to establish a standard animal model of severe burn-blast combined injury in rats and also to investigate early phasic changes of blood coagulation. By using 54 Wistar rats, distance from explosion source (Hexogen) and size of burned body surface area were determined to induce severe burn-blast combined injury.

Experimental study on neuroendocrinological and immunological characteristics of the military-trained artillerymen.

Background: Over one million soldiers were treated for battle- or training-fatigue during World War II. Of all ground combat troops, 37% were discharged for psychiatric reasons due to fatigue. The neuroendocrinological and immunological systems played important roles in the work-related fatigue of military personnel.
