Asbestosis in Experimental Animals

Asbestosis in experimental animals.

Previous animal experiments with asbestos dusts have been almost entirely confined to chrysotile asbestos. It was, therefore, decided to investigate the effects of mill dusts from the three types of asbestos that are produced commercially in South Africa, namely chrysotile, amosite, and crocidolite. Chrysotile and amosite samples were relatively pure while in contrast the crocidolite dust was f...

Scorpion Venom Pisoning in Experimental Animals

Experimental asbestosis: an investigation of functional and pathological disturbances. I. Methods, control animals and exposure conditions.

The measurement of respiratory function and quantitative assessment of changes in lung morphology are described in a long-term study of asbestos-exposed guinea pigs. Resistance and dynamic compliance of the guinea pig respiratory system were measured non-destructively, and the tidal volume and rate of spontaneous breathing were also determined. A point counting technique was used with histologi...

Fasting and Experimental Animals, Detrimental or Positive?

While fasting has been practiced for centuries, its beneficial effects was unknown until recently. This review tries to analyze the current literature of how fasting and intermittent fasting (IF) could affect clinical pathological parameters, learning, mood and brain plasticity. The effects of different ways of fasting on metabolism and stress were also explored. Animal experiments have elucida...

Sepsis Models in Experimental Animals

Sepsis develops as a common inflammatory response to various infections. It runs with the picture of a complex heterogeneous syndrome which often leads to the development of multiple organ dysfunctions and causes the death of millions of people worldwide. For various reasons, detailed research of sepsis in humans is difficult to conduct; therefore, a lot of efforts have been made to model it. P...
