Benefits of kinesiotherapy and aquatic rehabilitation on sickle cell anemia. A case report

G. Tinti, Somera, Jr., R., Valente, F. M., and Domingos, C. R. B., Benefits of kinesiotherapy and aquatic rehabilitation on sickle cell anemia. A case report, vol. 9. pp. 360-364, 2010.

The process of hemoglobin polymerization and the consequent sickling of red blood cells that occurs in patients with sickle cell disease shortens the half-life of red blood cells. It causes vaso-occlusive complications, as well as pain and pulmonary and cardiovascular dysfunction. We evaluated an aquatic rehabilitation program used for patients with sickle cell anemia and examined the possible benefits that exercise in warm water has for the circulatory system, for relieving pain, and for increasing lung capacity. The patient was a 32-year-old female.

Ala-9Val polymorphism of Mn-SOD gene in sickle cell anemia

S. Sogut, Yonden, Z., Kaya, H., Oktar, S., Tutanc, M., Yilmaz, H. R., Yigit, A., Ozcelik, N., and Gali, E., Ala-9Val polymorphism of Mn-SOD gene in sickle cell anemia, vol. 10, pp. 828-833, 2011.

Oxidative stress may be contributory to the pathophy­siology of the abnormalities that underlie the clinical course of sickle cell anemia. We looked for a possible genetic association between the functional polymorphism Ala-9Val in the human Mn-SOD gene and sickle cell anemia. One hundred and twenty-seven patients with sickle cell anemia and 127 healthy controls were recruited into the study.

Evaluation of the mutagenic activity of hydroxyurea on the G1-S-G2 phases of the cell cycle: an in vitro study

P. Danielle L. de Lima, Cardoso, P. Cerqueira, Khayat, A. Salim, Bahia, Mde Oliveir, and Burbano, R. Rodríguez, Evaluation of the mutagenic activity of hydroxyurea on the G1-S-G2 phases of the cell cycle: an in vitro study, vol. 2, pp. 328-333, 2003.

Hydroxyurea is considered an antineoplastic drug, which also plays an important role in the treatment of sickle cell anemia patients. We evaluated and compared the clastogenic and cytotoxic effects of hydroxyurea, using chromosomal aberrations and mitotic index, respectively, as endpoints. In vitro short-term cultures of lymphocytes were exposed to several concentrations of this drug, at various cell cycle phases. There was a significant increase in the cytotoxicity of hydroxyurea at G1 and G1/S as well in the G2 phase of the cell cycle.
