As tolerance developed, the ability of the serum to augment the pyrogenic effect of endotoxin and production of endogenous pyrogen were diminished. When tolerance was produced by passive transfer, these 2 parameters were similarly affected. RES blockade did not reverse tolerance nor did it restore augmenting factor or markedly increase the animal's ability to elaborate endogenous pyrogen following injection with endotoxin. These observations suggest that serum inhibitors may mediate tolerance by inactivating the ability of serum to augment endotoxin.","PeriodicalId":20675,"journal":{"name":"Proceedings of the Society for Experimental Biology and Medicine","volume":" ","pages":"218-21"},"PeriodicalIF":0.0,"publicationDate":"1965-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3181/00379727-119-30141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40796825","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}

A simple preliminary fractionation method for the nondialyzable urinary carbohydrate containing solids is reported. Sodium chloride is added to urine to 0.58 M to precipitate CPC-I (Tamm and Horsfall mucoid). After dialysis and concentration, CPC-II is separated from AMP and glycopeptide with addition of (NH4)2SO4 to 100% saturation. 2. The present method enables (a) simultaneous quantitative evaluation of 3 carbohydrate-containing fractions in urine, (b) determination of the glycopeptide and AMP content of the AMP fraction, and (c) further fractionation of these into individual components. 3. The mean and standard error of the daily excretion of each component for all samples was: CPC-I—50 ±6mg; CPC-II—193 ± 23 mg; AMP— 13 ± 2 mg; and glycopeptide—15 ± 2 mg. With increasing age, the excretion of CPC-II is increased. The excretion of AMP is highest between 10–20 yrs of age. It decreases thereafter.","PeriodicalId":20675,"journal":{"name":"Proceedings of the Society for Experimental Biology and Medicine","volume":" ","pages":"193-9"},"PeriodicalIF":0.0,"publicationDate":"1965-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3181/00379727-119-30134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40799770","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}

A similar relationship for an avian species has not been established. Materials and methods. Adult male white Leghorn chickens (2.5 kg to 3.1 kg) kept in outdoor pens were used in these experiments. Experiments were conducted between February and May so the animals were adapted to cold. The tracheas, left carotid arteries and right brachial veins were can-nulated under local anesthesia (ethyl ch-loride). Incisions were closed and 20 mg/animal of heparin (sodium) was administered intravenously. After waiting approximately 15 minutes, a control sample of blood was drawn. Succinylcholine was injected i.v., initially in a dose of 40 mg/animal and before each additional ventilating regimen in a dose of 20 mg/animal. The animals were over-ventilated artificially by connecting the tracheal cannula of the animal to a respiratory pump which ran at a stroke volume of 38 ml and a rate of 50 breaths per minute (1.9 1/min). Gas mixtures of 21% O2, and 0, 5 or 10% CO2 with the remainder as N2 were delivered to the animals on the over ventilation regimen. Presentation of gas mixtures was randomized to eliminate the possibility of sequence of presentation influencing the results. In some experiments only 0 and 5% CO2 were used. At the end of 30 minutes on a given gas mixture a 4 ml sample of arterial blood was drawn after first drawing 1/2 ml to clear the cannula. The portion of blood sample to be analyzed for lactate and pyruvate and glucose was drawn into a 2 ml syringe, transferred directly into a centrifuge tube containing 2 ml of chilled 10% trichloroacetic acid and mixed.","PeriodicalId":20675,"journal":{"name":"Proceedings of the Society for Experimental Biology and Medicine","volume":" ","pages":"261-3"},"PeriodicalIF":0.0,"publicationDate":"1965-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3181/00379727-119-30153","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40796557","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}
