“…This preparation is endotoxin free and composed of 34.06% C, 6.15% H, 50.30% O, 5.69% S, and 3.23% N. Following this treatment, two polymer peaks were resolved by size exclusion chromatography: peak 1 was approximately 1 ϫ 10 6 Da and represented 1% of the total polymer mass, and peak 2 was about 1.5 ϫ 10 4 Da and represented 99% of the total polymer mass (76). These polymers formed a triple helix in solution and were biologically active.…”

“…The TLR4 deleted strain (C57BL/10ScCr) and wild-type (WT; C57BL/10ScSn) mice were obtained from Jackson Laboratory (Bar Harbor, ME) as described previously (13 GP. Water soluble GP was prepared and chemically characterized in our laboratory as previously described (34). We have previously demonstrated that GP will increase long-term survival in CLP-induced sepsis (30,31), improves cardiac function in CLP-induced sepsis/septic shock (9), and decreases myocardial injury in response to ischemia-reperfusion (I/R) injury (16).…”

“…O maior obstáculo da utilização clínica das β-glucanas é a falta relativa de solubilidade em meio aquoso. Segundo Williams e colaboradores 74 , β-D-glucanas (1→3) isoladas da parede celular da levedura Saccharomyces cerevisiae como micropartículas insolúveis (1-2 μm) não induzem nenhuma toxicidade quando administradas intralesão ou topicamente, porém o uso sistêmico (intravenoso) da forma microparticulada está associado com hepatoesplenomegalia, formação de granulomas, microembolia e aumento da sensibilidade às endotoxinas. Um dos primeiros procedimentos empregados para solubilização destas moléculas microparticuladas foi a sulfatação da glucana de Saccharomyces cerevisiae.…”

“…O objetivo primário foi aumentar a polaridade da molé-cula aumentando, conseqüentemente, sua solubilidade em água e preservando a ação imunobiológica. Este objetivo foi alcançado, considerando-se que as glucanas sulfatadas exerceram potente atividade antimicrobiana e antineoplásica e, particularmente, um efeito inibitório 74 contra o vírus causador da imunodeficência humana (HIV).…”
