Analysis of DNA damage using the comet assay in infants fed cow's milk.

It has been hypothesized that non-human milk feeding may increase the risk for cancer or for a specific cancer or group of cancers as well as the risk for diseases such as type-1 diabetes mellitus and Crohn's disease. Regarding DNA damage leading to cancer development in the absence of human milk protection, a comparison between infants fed human milk and cow's milk has been performed. Each group consisted of 35 infants, whose ages ranged from 9 to 12 months.

Antioxidant enzymes and lipid peroxidation in adolescents with inhalant abuse.

Glue and thinner sniffing is a serious medical problem since the volatile constituents of these substances can lead to severe damage to bone marrow, liver, kidney, brain, and heart. The exact mechanisms responsible for tissue and organ damage in children with inhalant abuse have not yet been determined. In this study, we aimed to determine the levels of antioxidant enzymes and malondialdehyde in children with inhalant abuse.

DNA damage in children treated with imipramine for primary nocturnal enuresis.

Background: Despite the fact that primary nocturnal enuresis (PNE) is self-limited and pathologically benign, the emotional stress and inconvenience that it produces, warrants treatment. Imipramine is one of the widely used drugs in PNE treatment. Although some mutagenic effects were suggested in imipramine administration, this toxicity has never been investigated in enuretic patients.

Selenium and zinc levels in volatile substance abusers.

Plasma and erythrocyte levels of selenium (Se) and zinc (Zn) have not been investigated in volatile (inhalant) substance abusers previously, although changes in the activities of antioxidant enzymes resulting from oxidative damage caused by various constituents of volatile substances have been shown in a few animal and human studies. Concentrations of these two elements in erythrocytes and plasma of 37 adolescents with inhalant abuse were measured by atomic absorption spectrophotometry and compared with those of 37 age-matched healthy controls. Erythrocyte and plasma levels of Se and plasma level of Zn were significantly lower in the study group when compared to the control group.

The use of the corpus cavernosum for the administration of phenobarbital: an experimental study in dogs.

Status epilepticus (SE) is classically defined as a generalized tonic-clonic seizure lasting longer than 30 min. Prolonged seizure activity can be resulted in irreversible cerebral injury. In addition, the existence evidence suggests that the longer the duration of the seizure activity is less likely to be controlled.

Intracavernous application of diazepam: an alternative route of the seizure treatment--an experimental study in rabbits.

Background: There is a general need to terminate seizures as soon as possible using anticonvulsant drugs via an intravenous (i.v.) route, but it is often difficult to achieve a secure i.

Preliminary study on DNA damage in non breast-fed infants.

Background: There are many advantages of human milk for infants, including protection against cancer development and the advantages have been emphasized in several studies. In this study, infants fed by human milk has been compared with those fed by cow's milk concerning DNA damage.

Methods: The level of genetic damage in the peripheral blood lymphocytes of infants who were fed mainly by cow's milk and breast milk has been studied by sister chromatid exchange (SCE) analysis, which is a sensitive measurement of chromosomal damage.
