DNA damage in children exposed to secondhand cigarette smoke and its association with oxidative stress.

Objective: To compare oxidative status, total antioxidant capacity and values of DNA damage in peripheral blood lymphocytes in children exposed to secondhand cigarette smoke with healthy controls.

Design: Analytical, Observational.

Participants: 54 children without any chronic diseases, attending the healthy child monitoring polyclinic.

Treatment of congenital ichthyosis with acitretin: a case report.

The authors assessed the clinical efficacy, tolerability and safety of acitretin in a patient with ichthyosis. A newborn infant with ichthyosis who presented at birth with collodion baby appearance, was treated with acitretin. A moderate response to acitretin therapy (1 mg/kg/day) administered for 6 months was observed, with improvement in cutaneous lesions.

[Clinico-pathogenetic aspects of infectious toxicosis in infants caused by acute pneumonia].

Altogether 101 children under one year of age with infectious toxicosis due to acute pneumonia were examined for the clinical, roentgenomorphological and biochemical aspects of the given condition. The clinical aspects were delineated on the basis of the universal status covered by the formalized case report. The biochemical processes were analyzed according to the content of peroxidation products of membrane lipids, the concentration of hydrogen peroxide, phospholipase activity, antioxidant and antiperoxide defence of the blood as well as according to the physical constants of red blood cell membranes.

[Clinical value of studying phospholipids in young children with acute pneumonia].

A study was made of phospholipid metabolism in 268 children aged 1 month to 3 years, who were in a critical condition consequent on acute complicated pneumonia. Unbalance of that type metabolism was revealed. It consisted in intensive accumulation of lysophosphatidylcholine, sphingomyelin in the stroma of red blood cells and in a decrease of their pool in the blood plasma as well as in a reduction of the content of phosphatidylserine and phosphatidylethanolamine towards the plasma pool.

[Changes in the activity of antioxidant enzymes in ischemia and subsequent reperfusion of the myocardium].

Transitory coronary failure of the myocardium was accompanied by a considerable reduction in the activity of superoxide dismutase, glutathione peroxidase and glutathione transferase, with the activity of the enzymes under study being not different in the ischemized and distant from ischemia zones of the myocardium. Reperfusion did influence the activity of superoxide dismutase and glutathione peroxidase after 10 and 40 minutes of ischemia, whereas following 120 minutes of ischemia the activity of superoxide dismutase ascended after 10 and 40 minutes of reperfusion while the activity of glutathione peroxidase remained unchanged.
