Chromosomal Aberrations in Ophthalmology

Propranolol induced chromosomal aberrations in Chinese hamster ovary cell line

Propranolol (PL), a non-selective beta-blocker, is a cardiovascular drug widely used to treat hypertension. The present study was concerned with assessing the cytogenetic effects of this drug on Chinese hamster ovary (CHO) cell line. MTT assay was then carried out to determine the cytotoxicity index (IC50) of the drug. The IC50 value of PL was 0.43±0.02 mM. To investigate the clastogenic effect...

Chromosomal aberrations in iris melanomas.

BACKGROUND Uveal melanomas can develop in the choroid, ciliary body and iris. In choroidal and ciliary body melanomas, specific chromosomal changes correlate with metastatic disease. Iris melanomas have a better prognosis than choroidal melanomas, and it would be interesting to know if they share chromosomal changes. In addition, iris melanomas might harbour UV-induced mutations of tumour suppr...

Chromosomal aberrations in Perinatal Asphyxia

This study was conducted to evaluate the level of chromosomal damage in perinatal asphyxia and correlate it with severity of asphyxia. Fourty term neonates with asphyxia and twenty term babies without asphyxia were included in this case control study. Blood samples were collected within 24 hours of birth for karyotyping and oxidative stress by serum malondealdehyde (MDA) estimation. The degree ...

Chromosomal aberrations in infective hepatitis.

Structural chromosomal aberrations, in the form of breaks, were found in a significantly higher proportion of bone marrow cells in patients with infective hepatitis than in controls. These anomalies were observed during the first and third weeks after the onset of jaundice but had subsided by the sixth week. Chromosomal aberrations did not appear to be related to the severity of infective hepat...
