Preparation of Collodion Sacs for Use in Bacteriology
A standardized method is described in detail by which collodion sacs suitable for intraperitoneal incubation and for other bacteriological experiments may be produced in large numbers, sterilized, and handled with convenience and the minimum danger of contamination. Various factors influencing permeability have been subjected to experiment. Like Brown, we found that immersion in alcohol is the ...
متن کاملV. Survival of the Virus in Collodion Sacs Implanted Intraabdominally in Guinea Pigs. By
In a previous paper 1 of this series, one of the writers showed tha t the typhus virus found in the blood of guinea pigs during the height of typical experimental typhus fever does not survive at 37°C. in anaerobic media for as long a period as in the same media under aerobic conditions, When oxygen is excluded, the viabil i ty period is 24 to 48 hours, whereas in the same media unpro tec ted f...
متن کاملEffect of Sulfanilamide Injected Subcutaneously into Rabbits upon Hemolytic Streptococci Contained in Collodion Sacs Implanted Intraperitoneally.
Experiments were undertaken to determine the effect of sulfanilamide upon hemolytic streptococci growing within the animal body, yet protected by collodion membranes from phagocytosis. The method of manufacturing the collodion sacs used in the experiments has previously been described (Harris, 1939). Theories regarding the r6le of phagocytosis in the drug's action have been amply discussed by L...
متن کاملThe Joy of Sacs
This paper investigates an idea that was put forward (and hinted at in Fitch, 2000) by Tecumseh Fitch at the Cradle of Language conference in Stellenbosch, South Africa. The idea is that air sacs may have played an important role in early hominid vocalizations. Many other primates have air sacs, notably chimpanzees, gorillas and orangutans. It is therefore likely that our latest common ancestor...
متن کاملComparative Study on the Effects of Ziziphus Spina-christi Alcoholic Extracts on Growth and Structural Integrity of Bacterial Pathogens
In different folk medicine Ziziphus spina-christi is used for different purposes such as pneumonia, dysentery, scorpion stings, cough, constipation, intestinal worms and fever. The aim of this study was evaluation and comparing the antibacterial activity of methanolic and ethanolic extracts of Ziziphus spina –christi as well as subsequent structural changes in affected bacteria. For this purpos...
