Abstract
The peritoneal cellular response to colloidal carbon has been studied in NZB, NZW, BWF1, BALB/c, CBA and C3Hf mice aged 8 to 10 weeks. The overall patterns of total and differential peritoneal cell counts was similar in all 6 strains of mice. No inter-strain differences were noted in either the removal of carbon from the peritoneal cavity or the distribution of carbon in the fixed tissue macrophages. The results show that phagocytosis of colloidal carbon, an inert particle, is normal in New Zealand mice.
Intravenous carbon clearance studies performed on NZB, BALB/c and CBA mice showed that phagocytosis of carbon was identical in each strain when correction was made for variations in liver and spleen weight.
