Objective To study and compare the protective effects of pmtease inhibitor and corticosteroid on endotoxin-indueed acute lung injury in order to guide the choice of appropriate drugs. Method Thirty-two New Zealand rabbits were randomly divided(random number) into four groups with 8 rabbits in each, namely normal controls(C) ; lipopolysaecharide(LPS) group(L) ; ulinastatin(UTI) group(U) and dexamcthasone(DEX) group (D) .Except group C, all rabbits were injected with a dose of LPS 600 μg/kg iv. Meanwhile the rabbits in group U,group D received UTI(100 000 μ/kg), DEX(5 mg/kg), respectively. The specimens were collected 4 hours later for detecting the levels of TNF-α and NO in serum, and blood gas analysis, histological manifestations, the lung wet/dry weight ratio, lung tissue MPO and SOD activity, lung tissue MDA. Data were analyzed by ANOVA (SNK- q test), and P < 0.05 was considered as significantly different. Results Compared with group C, the lungs of the rabbits in group L had inflammatory granulocyte infdtration, diffused alveolar septum thickening and hemorrhagic spots were observed in pathological examinations. The histological changes of group U and group D were much lessened than those in group L. As groups U and D were compared with group L, there were significant differences inmany biomarkers including lung wet/dry weight ratio[(5.02±0.11),(4.93±0.13) vs.(5.37 ±0.29)],lung tissue MPO activity[(0.51 ± 0.05),(0.54±0.07) vs.(0.82 ± 0.09)] and MDA[(0.82 ±0.05),(0.81 ±0.04) vs.(0.96±0.05)], NO[(296.2± 11.7),(291.7 ± 15.8) vs.(351.8±19.6)] and TNF-α[group D(2.021 ± 0.122) vs. group L(4.999 ± 0.139)],lung tissue SOD activity[(120.3 ± 6.1),(122.6±3.5) vs.(105.1 ± 8.5)] and blood gas analysis[pH(7.30±0.23),(7.30±0.17) vs.(7.22±0.45) and PaO_2( 101.9 ± 6.8).( 102.5 ± 4.7) vs.(80.3 ± 3.3)] ; but there were no differences of above mentioned biomarkers between group U and D( P > 0.05). And there were no significant differences in PaCO_2 betweeu group U and D and group L[(37.0 ± 3.3),(37.6 ± 3.0) vs.(34.8 ± 2.3)]( P > 0.05). Conclusions The protective effects of ulinastatin on endotoxin-induced acute lung injury is comparable to those of dexamethasone, thus the former may be a clinical substitute for the latter with less side effects.

OBJECTIVETo compare alveolar bone mineral density (BMD) changes of the male and female diabetes rats, and male diabetic rats BMD in systemic change.
METHODS40 Wistar rats were divided into diabetic group (15 female rats and 15 male rats) and control group (5 female rats and 5 male rats). Models of diabetes rats were made by peritoneal injection of streptozotocin (STZ). Blood glucose, serum insulin, indicators of bone metabolism as well as BMD of mandibular alveolar bone, femur and lumbar spine were examined.
RESULTSThe BMD of mandibular alveolar bone in male rats was higher than the female rats in the two groups (P<0.05). The BMD of mandibular alveolar bone of male and female diabetic rats in the diabetic group was lower than that in the control group (P<0.05). The BMD of male rats in the control group was femur, mandibular alveolar bone, lumbar spine from high to low. The BMD of male rats in the diabetic group was mandibular alveolar bone, femur, lumbar spine from high to low.
CONCLUSIONOsteoporosis happen to mandibular alveolar bone of female and male diabetes rats, especially in female rats. The BMD of mandibular alveolar bone, femur and lumbar spine in the male diabetic rats were lower than that in the control group. Mandibular alveolar bone density changes of diabetic rats was in line with the lumbar spine and femur's, or mandibular alveolar bone density changes of diabetic rats lags behind the lumbar spine and femur's.
