Originator of the hormesis concept: Rudolf Virchow or Hugo Schulz

Area of Science:

• Toxicology
• History of Science
• Cell Biology

Background:

• The concept of hormesis, a biphasic dose-response relationship, is central to toxicology.
• Henschler (2006) disputed Calabrese and Baldwin's claim that Hugo Schulz originated the hormesis concept.
• Henschler cited Rudolf Virchow's 1854 paper on ciliary beating as evidence of an early hormesis observation.

Purpose of the Study:

• To re-evaluate the historical claims regarding the origin of the hormesis concept.
• To critically assess Henschler's interpretation of Rudolf Virchow's 1854 paper.
• To determine if Virchow's original work supports a hormetic dose-response.

Main Methods:

• Review and translation of Rudolf Virchow's 1854 paper from German to English.
• Analysis of the experimental data and conclusions presented in Virchow's paper.
• Comparison of Henschler's interpretation with the translated content of Virchow's paper.

Main Results:

• The recent English translation of Virchow's 1854 paper does not support Henschler's interpretation.
• Virchow's findings on the effects of agents on ciliary beating do not demonstrate a hormetic-biphasic dose response.
• The widespread acceptance of Henschler's interpretation, based on previous literature, is challenged.

Conclusions:

• Rudolf Virchow's 1854 paper does not provide evidence for the early observation of hormesis.
• Henschler's claim regarding Virchow's contribution to the hormesis concept is not supported by the translated text.
• The historical understanding of the hormesis concept's origin may require revision.
