Experiments on the Rôle of Lymphoid Tissue in the Resistance to Experimental Tuberculosis in Mice
نویسندگان
چکیده
Mice with high lymphocyte counts and increased activity of the lymphoid tissue induced by one exposure to intense dry heat exhibit a marked increase in the resistance to large doses of bovine tubercle bacilli as compared with that shown by control animals given a similar inoculation. This resistance, judged by the time of survival after inoculation, is increased from two- to threefold. The average length of life after inoculation for three groups of heated mice was 88, 69, and 67 days respectively, while the control groups averaged 16, 29, and 28 days respectively.

متن کاملThe Effect of Eight Weeks of Aerobic Exercise on the Expression of Senescence Proteins P53 and P16 in Pancreatic Tissue of Diabetic Mice
Background: Chronic hyperglycemia is associated with an increase in cellular damage due to oxidative stress and increases insulin resistance and also increases in p53 and p16 beta cells, leading to the induction of senescence in pancreatic insulin-secreting cells. The aim of this study was the effect of eight weeks of aerobic exercise on the expression of senescence proteins P53 and P16 in the ...

Background and Aim: One of the most common metabolic diseases is diabetes with hyperglycemic properties and endogenous insulin dysfunction. This study aimed to evaluate the effect of 10 weeks HIIT on HIF-1α gene expression in heart tissue of rats with type 2 diabetes. Methods: In this experimental study, 36 Wister rats with a mean weight of 200±58g were randomly assigned to control, diabetic,...
