Summary.

The penetration rate of ethanol in human tendons was studied to in order to define the conditions which were necessary to achieve an inactivating concentration against the Human Immunodeficiency Virus (HIV) within the tendon. The rate of alcohol penetration was found to be slow and did not differ with different types of tendons. An average ethanol concentration of 14% (v/v) was measured in human tendons after they had been immersed for 2 h in 70% (v/v) ethanol, and a concentration of 19% (v/v) was reached after 3 h. Ethanol immersion of human tendons may represent an additional safety procedure in inactivating the HIV virus provided the duration is at least 3 h.

Résumé.

La pénétration de l’éthanol dans les allogreffes tendineuses humaines a étéétudiée pour établir les conditions nécessaires à l’obtention d’une concentration inactivatrice pour le HIV. La pénétration tendineuse de l’éthanol est assiz lente et ne diffère pas selon les différents types de tendons. Une concentration moyenne de 14% (v/v) a été mesurée après une immersion de 2 heures dans une solution d’éthanol 70% (v/v), tandis qu’une concentration de 19% (v/v) est obtenue après 3 heures. Une immersion d’une durée minimale de 3 heures est donc nécessaire si une inactivation virale du HIV par l’alcool est envisagée.
