Zn in burn skin increased significantly on 3, 7 days in W group and was 1.3, 1.5 times as much as that of N group. Serum growth hormone increased in all groups postburn. The highest level appeared in H group. Hydroxyproline in burn skin decreased in all groups, but it began to increase on 7 day postburn in W group.Conclusion: Supplementation of Zn by diet rapidly raises the levels of Zn in serum, burn skin and growth hormone. It is beneficial to apply Zn to the wound to improve wound healing. Hydroxyproline increased significantly with application of Zn to burn wound. It is better to supply Zn by diet and topical application simultaneously.","PeriodicalId":77478,"journal":{"name":"Zhonghua zheng xing shao shang wai ke za zhi = Zhonghua zheng xing shao shang waikf [i.e. waike] zazhi = Chinese journal of plastic surgery and burns","volume":"14 6","pages":"425-8"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21317324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of adhesion molecules CD11a, CD11b, and ICAM-1 on the PMN adhesion and transmigration were also studied.Method: In the present study fluorescent assay, EC sheet cultured on the 5 microns permeable membrane and antibody blocking technique were used to study the PMN adhesion and transmigration in vitro.Result: It was found that the serum from SII rats could promote PMN adhesion to CEC sheet. After being cultured with the serum for 12-24 h, PMN adhesion to CEC was more than three times of that in control. The serum also enhanced PMN transmigration through the CEC sheet in vitro, doubling the amount observed in control when the sheet was cultured with the serum for 24 h. Based on the above data it was believed that the SII rat serum could enhance PMN adhesion to and transmigration through lung capillary, and the percentages of PMN adhesion and transmigration were found to be positively correlated (r = 0.975). Furthermore, the antibodies against CD11a, CD11b, and ICAM-1 reduced PMN adhesion 44%, 55% and 51%, respectively, and at the same time decreased PMN transmigration 39%, 65%, and 58%, respectively.Conclusion: In the presence of serum obtained from SII rats PMN adhesion to and transmigration through CEC sheet increased, which is the possible underlying mechanism responsible for PMN infiltration in vitro. Moreover, the adhesion molecules such as CDA11a, CD11b, and ICAM-1 play an important role in the process. Infiltrated PMN could release oxygen free radicals and protease to injure lung tissue.","PeriodicalId":77478,"journal":{"name":"Zhonghua zheng xing shao shang wai ke za zhi = Zhonghua zheng xing shao shang waikf [i.e. waike] zazhi = Chinese journal of plastic surgery and burns","volume":"14 6","pages":"414-7"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21317320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rheological parameters such as red cell deformability (RED) and platelet aggregation rate (PAR), as well as endothelin-1 (ET-1) in venous blood drained from electrical burn wounds and contents of ATP in damaged muscle were measured at time intervals of 2 h, 24 h, 48 h and 72 h postburn.Results: The changes in the parameters mentioned above were significant following electrical injury. The administration of PGE1 showed an advantageous effect in prevention of thrombosis and muscle \"progressive necrosis\" through improvement in RCD, reduction of PAR and the content of ET-1 in local circulation.Conclusion: RCD, PAR and the content of ET-1 in local circulation changed significantly following electric injury and may play an important role in the process of \"progressive necrosis\".

A 3-D partial dynamic analyzer was used to determine the inspiratory and expiratory flow velocity, and arterial blood samples were collected for blood-gas analysis during spontaneous respiration. Intravenous muscle relaxant was given quickly and the animals were kept apneic and then vapor (105 degrees C) was inhaled for 5 seconds. HFJV was carried out at random under 5 different conditions, each for 20 minutes. Changes in inspiratory velocity (Vi), expiratory velocity (Ve), Reynole's number, PaCO2, PaO2, and PIP were observed.Result: 1. During spontaneous respiration, airflow was in form of laminar flow when Re < 1000, and expiratory airflow was either laminar or turbulent when 1000 < Re < 1500. 2. During HFJV, both expiratory and inspiratory airflow were turbulent when Re > 1500. 3. The expiratory velocity with HFTJV increased significantly (P < 0.05). PaCO2 decreased significantly (P < 0.05) compared with HFJV. Obvious negative correlation was found between them (r = -0.9216, P < 0.05), meanwhile inspiratory velocity had an increasing tendency.Conclusion: 1. HFJV could maintain normal ventilation of dogs with inhalation injury. The mechanism might be associated with turbulent flow. 2. On the basis of HFJV, HFTJV increases inverse jet airflow, thus the respiratory airflow velocity may be increased and CO2 elimination improved.","PeriodicalId":77478,"journal":{"name":"Zhonghua zheng xing shao shang wai ke za zhi = Zhonghua zheng xing shao shang waikf [i.e. waike] zazhi = Chinese journal of plastic surgery and burns","volume":"14 6","pages":"418-21"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21317322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coal mine explosion includes two types, i.e., gas explosion and coal dust explosion. 2. This kind of burn is a combined injury with pathologic changes of burns as the main feature. Mechanical injury is the chief cause of early death. Blast injury mainly damages the lungs. The occurrence of carboxyhemoglobinemia is not often. 3. The amount of fluid infusion in the first 24 h in exudation phase is 8% less of the traditional formula. Alkaline balanced salt solution is supplied as electrolyte solution, which can provide 45% of necessary HCO3- for correction of acidosis. 4. No thorough debridement is imposed in the treatment of burn wound. Baking with electric bulb with topical SD-Ag in semi-exposure state can be used. 5. Inhalation injury chiefly occurs in upper respiratory tract. The main bacterial species causing complicated lung infection are Pseudomonas aeruginosa and Staphylococcus aureus. 6. When MSOF occurs, the most frequently involved organ and system are the kidney and respiratory system. 7. The main bacteria causing systemic invasive infection are enteric bacilli and Pseudomonas aeruginosa. Enteric bacilli infection may be enterogenic. The latter infection is chiefly the result of cross infection in hospital.Conclusion: The burn caused by coal mine explosion is a combined injury characterized by pathologic changes of burn as the main issue. This kind of burn has two types, i.e., gas-explosion-burn and coal-dust-explosion-burn.","PeriodicalId":77478,"journal":{"name":"Zhonghua zheng xing shao shang wai ke za zhi = Zhonghua zheng xing shao shang waikf [i.e. waike] zazhi = Chinese journal of plastic surgery and burns","volume":"14 6","pages":"436-8"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21316497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
