Few studies have addressed brain damage after paraquat poisoning. Ulinastatin is a protease inhibitor that can effectively stabilize lysosomal membranes, prevent cell damage, and reduce the production of free radicals. This study assumed that ulinastatin would exert these effects on brain tissues that had been poisoned with paraquat. Rat models of paraquat poisoning were intraperitoneally injected with ulinastatin. Simultaneously, rats in the control group were administered normal saline. Hematoxylin-eosin staining showed that most hippocampal cells were contracted and nucleoli had disappeared in the paraquat group. Fewer cells in the hippocampus were concentrated and nucleoli had dis- appeared in the ulinastatin group. Western blot assay showed that expressions of GRP78 and cleaved-caspase-3 were significantly lower in the ulinastatin group than in the paraquat group. Immunohistochemical findings showed that CHOP immunoreactivity was significantly lower in the ulinastatin group than in the paraquat group. Terminal deoxynucleotidyl transferase-medi- ated dUTP nick end labeling staining showed that the number of apoptotic cells was reduced in the paraquat and ulinastatin groups. These data confirmed that endoplasmic reticular stress can be induced by acute paraqnat poisoning. Ulinastatin can effectively inhibit this stress as well as cell apoptosis, thereby exerting a neuroprotective effect.展开更多

Oxygenation index, mortality rate [intensive care unit(ICU) mortality rate, 28-d mortality rate] and length of ICU stay were compared between ulinastatin group and conventional therapy group. Meta-analysis was performed by using Rev Man 5.1.RESULTS: Twenty-nine RCTs with 1726 participants were totally included, the basic conditions of which were similar. No studies discussed adverse effect. Oxygenation index was reported in twenty-six studies(1552 patients). Ulinastatin had a significant effect in improving oxygenation [standard mean difference(SMD) = 1.85, 95%CI: 1.42-2.29, P < 0.00001, I2 = 92%]. ICUmortality and 28-d mortality were respectively reported in eighteen studies(987 patients) and three studies(196 patients). We found that ulinastatin significantly decreased the ICU mortality [I2 = 0%, RR = 0.48, 95%CI: 0.38-0.59, number needed to treat(NNT) = 5.06, P < 0.00001], while the 28-d mortality was not significantly affected(I2 = 0%, RR = 0.78, 95%CI: 0.51-1.19, NNT = 12.66, P = 0.24). The length of ICU stay(six studies, 364 patients) in the ulinastatin group was significantly lower than that in the control group(SMD =-0.97, 95%CI:-1.20--0.75, P < 0.00001, I2 = 86%). CONCLUSION: Ulinastatin seems to be effective for ALI and ARDS though most trials included were of poor quality and no information on safety was provided.展开更多

This study aimed to explore the effects of UTI on paraquat-induced-oxidative stress in human type II alveolar epithelial cells. METHODS： The human type II alveolar epithelial cells, A549 cells, were cultured in vitro. The A549 cells were treated with different concentrations of paraquat （200, 400, 600, 800, 1 000, 1 200 pmol/L） and ulinastatin（0, 2 000, 4 000, 6 000, 8 000 U/mL） for 24 hours, the cell viability was measured by cell counting kit-8 and the median lethal concentration was selected. In order to establish an in vitro model of paraquat intoxication and to determine the safe dose of ulinastatin, we calculated LD50 using cell counting kit-8 to determine the survival rate of the cells. A549 cells were divided into normal control group, paraquat group and paraquat＋ulinastatin group. The levels of malondialdehyde （MDA） and myeloperoxidase （MPO） were detected by biochemistry colorimetry, while the level of reactive oxygen spies （ROS） was detected by DCFH-DA assay. RESULTS： The survival rate of A549 cells treated with different concentrations of paraquat decreased in a concentration-dependent manner. Whereas there was no decrease in the survival rate of cells treated with 0-4 000 U/mL ulinastatin. The levels of MDA, MPO, and ROS were significantly higher in the paraquat group than in the normal control group after 24-hour-exposure. And the survival rate of the paraquat＋ulinastatin group was higher than that of the paraquat group, but lower than that of the normal control group. The levels of MDA, MPO, and ROS were lower than those of the paraquat group. CONCLUSION： Ulinastatin can alleviate the paraquat-induced A549 cell damage by reducing oxidative stress.展开更多

文摘BACKGROUND： Ulinastatin （UTI） is a urinary trypsin inhibitor extracted and purified from urine of males. This study aimed to explore the effects of UTI on paraquat-induced-oxidative stress in human type II alveolar epithelial cells. METHODS： The human type II alveolar epithelial cells, A549 cells, were cultured in vitro. The A549 cells were treated with different concentrations of paraquat （200, 400, 600, 800, 1 000, 1 200 pmol/L） and ulinastatin（0, 2 000, 4 000, 6 000, 8 000 U/mL） for 24 hours, the cell viability was measured by cell counting kit-8 and the median lethal concentration was selected. In order to establish an in vitro model of paraquat intoxication and to determine the safe dose of ulinastatin, we calculated LD50 using cell counting kit-8 to determine the survival rate of the cells. A549 cells were divided into normal control group, paraquat group and paraquat＋ulinastatin group. The levels of malondialdehyde （MDA） and myeloperoxidase （MPO） were detected by biochemistry colorimetry, while the level of reactive oxygen spies （ROS） was detected by DCFH-DA assay. RESULTS： The survival rate of A549 cells treated with different concentrations of paraquat decreased in a concentration-dependent manner. Whereas there was no decrease in the survival rate of cells treated with 0-4 000 U/mL ulinastatin. The levels of MDA, MPO, and ROS were significantly higher in the paraquat group than in the normal control group after 24-hour-exposure. And the survival rate of the paraquat＋ulinastatin group was higher than that of the paraquat group, but lower than that of the normal control group. The levels of MDA, MPO, and ROS were lower than those of the paraquat group. CONCLUSION： Ulinastatin can alleviate the paraquat-induced A549 cell damage by reducing oxidative stress.
文摘BACKGROUND:Paraquat(PQ) is an effective herbicide and is widely used in agricultural production,but PQ poisoning is frequently seen in humans with the lung as the target organ.Currently,there are many studies on lung injury after PQ poisoning.But the kidney as the main excretory organ after PQ poisoning is rarely studied and the mechanisms of this poisoning is not very clear.In this study,we observed the expression of caspase-3 and livin protein in rat renal tissue after PQ poisoning as well as the therapeutic effects of ulinastatin.METHODS:Fifty-four Sprague-Dawley(SD) rats were randomly divided into three experimental groups:control group(group A),paraquat poisoning group(group B) and ulinastatin group(group C),with 18 rats in each group.Rats in group B and group C were administered intragastrically with 80mg/kg PQ,rats in group C were injected peritoneally with 100 000 U/kg ulinastatin once a day,while rats in group A were administered intragastrically with the same volume of saline as PQ.At 24,48,72 hours after poisoning,the expression of livin in renal tissue was detected by Westen blotting,the expression of caspase-3 was detected by immunohistochemistry,and the rate of renal cell apoptosis was tested by TUNEL detection.The histopathological changes were observed at the same time.RESULTS:Compared to group A,the expression of caspase-3 in the renal tissue of rats in groups B and C increased significantly at any time point.Compared with group B,the expression of caspase-3 in renal tissue of rats in group C decreased.Compared with group A,the expression of livin in renal tissue in rats of groups B and C increased significantly at any time point(P<0.01),especially in group C(P<0.01).TUNEL method showed that the rate of renal cell apoptosis index was higher in group B at corresponding time points than in group A(P<0.01),and was lower in group C at corresponding time points than in group B(P<0.01).CONCLUSION:UTI has a protective effect on the renal tissue of rats after paraquat poisoning through up-regulating the expression of livin and down-regulating the expression of caspase-3,but the regulation path still needs a further research.
