Ultrastructural alterations of skeletal muscle have been observed in adult chronic alcoholic patients. However, no such study has been performed on individuals prenatally exposed to ethanol. In order to determine if ethanol exposure in utero in the latter stages of muscle development was deleterious, skeletal muscle was obtained from newborn guinea pigs treated in the following manner. Six Hartly strain pregnant guinea pigs were randomly assigned to either the ethanol or the pair-intubated groups. Twice daily the 3 ethanol-treated animals were intubated with Ensure (Ross Laboratories) liquid diet containing 30% ethanol (6g/Kg pre-pregnant body weight per day) from day 35 of gestation until parturition at day 70±1 day. Serum ethanol levels were determined at 1 hour post-intubation by the Sigma alcohol test kit. For pair-intubation the Ensure diet contained sucrose substituted isocalorically for ethanol. Both food and water intake were monitored.

Az áttekintés az izomtömeg és az izomerő növelése célzatával alkalmazott hormonok (növekedési hormon, IGF-1, anabolikus-androgén szteroidok) és az izom fejlődésében szereplő, humán használatra kerülhető egyes faktorok fizikai aktivitással kapcsolatos élettanát és klinikai alkalmazásának lehetőségeit érinti. A hatásokat illetően mítoszok, a mellékhatásokat illetően alul- és túlértesültség egyaránt jellemzi e területet. A kórállapotok sorában, s nem csak a hiányállapotok szubsztitúciójában történnek terápiás próbálkozások, amelyekben figyelembe vehetők a sportolók, testépítők tapasztalatai is.
