The effects of membrane stroma from red cells and endotoxins on complement activation were also investigated. Plasma samples from rats were incubated with hemoglobin solutions or control solutions. C3 was measured using anti-rat C3 by nephelometric method. C3a was measured using radioimmunoassay. C3 and C3a were also determined in rats receiving hemoglobin solutions, red cell stroma solutions, or a solution containing complement activators (membrane stroma and bacterial endotoxins). There were no significant differences in C3 or C3a levels between the plasma incubated with hemoglobin solutions and the control plasma incubated with saline (P greater than 0.05). Compared with the saline incubated plasma, C3 was significantly lower and C3a significantly higher in the zymosan treated plasma (P less than 0.01). In hemoglobin infused rats, there was no significant difference between pre-versus post-infusion values in C3 and C3a. There was a significant increase in C3a in the rats receiving stroma suspension (P less than 0.05) or stroma and endotoxins (P less than 0.02). Polyhemoglobin and stroma-free hemoglobin did not cause significant changes in total leucocyte, differential, or platelet counts. Our study suggests that purified stroma-free Hb and polyHb do not activate complement, and that C3a is a more sensitive parameter for monitoring complement activation than C3. On the other hand, contaminates in hemoglobin preparations, such as membrane stroma or endotoxins, activate the complement system.","PeriodicalId":77498,"journal":{"name":"Biomaterials, artificial cells, and artificial organs","volume":"18 2","pages":"219-32"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/10731199009117303","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13518757","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}

This model allowed for the evaluation of direct effects of hemoglobin solutions without the influence of hemodynamic reflexes. Significant slowing of myocardiocyte beating rates were observed from 0.8 to 11.6 g.dl-1 stroma-free hemoglobin solution. Polymerization of hemoglobin into soluble crosslinked polyhemoglobin markedly reduced its negative chronotrophic effects by more than 50% at most concentrations assayed. Chronotropic potency (% change in beating rate from baseline per g.dl-1 was significantly higher for stroma-free hemoglobin when compared to polyhemoglobin and albumin solutions. Colloid osmotic potency (% change in beating rate from baseline per mmHg) however, was similar for stroma-free hemoglobin and polyhemoglobin but significantly lower for albumin solutions. This negative chronotropic effect may in part contribute to the transient bradycardia observed following hemoglobin infusion.","PeriodicalId":77498,"journal":{"name":"Biomaterials, artificial cells, and artificial organs","volume":"18 2","pages":"283-98"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/10731199009117307","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13519424","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}
