[Chronic persistent infections of anterior segment of eye: clinico-laboratory aspects].

Aim: Improvement of therapy of chronic ophthalmic infectious diseases during assessment of functioning of different arms of immune system.

Materials And Methods: Three hundred and fifty patients with chronic red-eye syndrome were tested by immunofluorescence assay on the presence of antigens of herpesviruses, adenoviruses and Chlamydia in samples from conjunctiva. Expression of 11 cytokines' genes was measured in peripheral blood mononuclear cells by reverse transcription polymerase chain reaction.

[A broad subfrontal access to the tumors in the base of the skull].

A total of 30 patients, aged 16 to 67, with neoplasms in the brain base and in paranasal sinuses were operated on, during 1997-2002, at Burdenko's Research Institute for Neurosurgery of the Russian Academy of Medical Sciences (RAMS). A majority of patients (21) had meningiomas. Other observations included: fibrous dysplasia of the anterior cranial fossa in 3 patients, chondroma in 2 patients, angiofibroma in 2 patients, pituitary adenoma in 1 patient and adamantinoma in 1 patient.

[Influence of the antioxidant status on the characteristics of lipids in tissues of animals after acute irradiation with sublethal doses].

The effect of the acute exposure to sublethal doses of X-rays on the interrelation between parameters of the lipid peroxidation regulatory system (lipid antioxidative activity, AOA; peroxide amount, lipid composition) was studied in liver, spleen and blood erythrocytes of CBA and SHK mice and rats within 1 month after irradiation. The reverse correlation between the lipid AOA values and the initial peroxide amount in lipids of the CBA mice spleen was found. The coefficient of the linear regression of this correlation for the exposed mice was 1.

[Surgery for hyperostotic cranial orbital meningiomas].

The paper analyzes surgical techniques for removal of hyperostotic cranial orbital meningiomas in 36 patients operated on in 1998 to 2000. In 19 cases hyperostosis extends to the upper and lower lid slits without involving the optic canal. It also spreads to the ethmoidal sinus in 6 cases to the frontal sinus in 3, and to the maxillary one in 2 patients.
