(1) Background: Regular exercise induces physiological and morphological changes in the organisms, but excessive training loads may induce damage and impair recovery or muscle growth. The purpose of the study was to evaluate the impact of Silymarin (SM) consumption on endurance capacity, muscle/cardiac histological changes, bodyweight, and food intake in rats subjected to 60 min of regular exercise training (RET) five days per week. (2) Methods: Male Wistar rats were subjected to an eight-week RET treadmill program and were previously administered SM and vitamin C. Bodyweight and food consumption were measured and registered. The maximal endurance capacity (MEC) test was performed at weeks one and eight. After the last training session, the animals were sacrificed, and samples of quadriceps/gastrocnemius and cardiac tissue were obtained and process for histological analyzes. (3) Results: SM consumption improved muscle recovery, inflammation, and damaged tissue, and promoted hypertrophy, vascularization, and muscle fiber shape/appearance. MEC increased after eight weeks of RET in all trained groups; moreover, the SM-treated group was enhanced more than the group with vitamin C. There were no significant changes in bodyweight and in food and nutrient consumption along the study. (5) Conclusion: SM supplementation may enhance physical performance, recovery, and muscle hypertrophy during the eight-week RET program.

Lysosomal acid lipase is an enzyme that intervenes in the last steps of lipid metabolism to hydrolyze cholesteryl esters. Patients with cryptogenic cirrhosis present a clear deficiency of lysosomal acid lipase with an unknown mechanism. Design: The present study has an analytical and retrospective design, of a sample of 55 patients with cryptogenic cirrhosis. The degree of association of lysosomal acid lipase was determined with the results of the enzymes alanine aminotransferase and alkaline phosphatase, as well as with the clinical manifestations of portal hypertension and splenic volume. The sensitivity and specificity of the test were determined for the diagnosis of the manifestations of portal hypertension. Results: The most frequent complication of portal hypertension was variceal hemorrhage with 40%, followed by ascites with 32.7%, and last, by hepatic encephalopathy, with 18.2%. Association by the x² test was without statistical significance with values of 0.177, 0.299, and 0.184 for encephalopathy, variceal hemorrhage, and ascites, respectively. The association of lysosomal acid lipase and splenic volume utilizing the Student t-test had a low degree of association and p >0.05. Through ROC curves, we obtained AUROC results close to 0.5. Conclusion: It is established that there is no correlation of the levels of activity of lysosomal acid lipase with the values of alanine aminotransferase and alkaline phosphatase, as well as with the presence or absence of clinical manifestations and by ultrasound of portal hypertension. Lysosomal acid lipase is not a good test for the diagnosis of the clinical manifestations of portal hypertension.
