[The effectiveness of photodynamic effects on the clinical and functional state of periodontal tissues in periodontitis].

Unlabelled: The aim the study. Increasing the effectiveness of treatment of chronic generalized periodontitis of moderate severity according to microhemodynamics and oxygenation in periodontal tissues.

Materials And Methods: A clinical and functional study and treatment of chronic generalized periodontitis of moderate degree were conducted in 56 people (22 men and 34 women) aged 37 to 55 years.

[Peripheral blood cells luminol-dependent chemiluminescence at the different stages of atopic dermatitis].

Unlabelled: Aim of this work was to record the luminol-dependent spontaneous and induced chemiluminescence at the different stages of atopic dermatitis.

Methods: Peripheral blood cells were obtained from adult patient with atopic dermatitis followed by the registration of luminol-dependent chemiluminescence on luminograph. Opsonized zymosan as well as yeasts Candida tropicalis have been used to induce the chemiluminescence.

[The evaluation of parameters of erythropoiesis and ferrokinetics in children born with extreme low body mass].

The article deals with the results of examination of 51 neonatal infants born with extreme low body mass in terms of gestation 22-31 week at first day of life and in 38-40 weeks of post conception age. The study established lowering of both values of indicators of erythrocyte sprout and level of iron-binding proteins in premature infants with extreme low body mass at birth and at achievement of age of mature infant.

[Oncolytic adenoviruses in anti-cancer therapy: current status and perspectives].

Lytic viral infection results in production of viral progeny, and lysis of the infected cells. Tumor cells are usually more sensitive to virus infection. Studies of viral oncolysis indicate that it could represent a promising alternative approach to cancer therapy.

Recombinant DNA-methyltransferase M1.BspACI from Bacillus psychrodurans AC: purification and properties.

A restriction-modification system from Bacillus psychrodurans AC (recognition sequence 5'-CCGC-3') comprises two DNA methyltransferases: M1.BspACI and M2.BspACI.

[Epitheliod hemangioendothelioma of the lung].

The authors give a morphological and immunohistochemical description of epitheliod hemangioendothelioma of the lung in two women aged 62 and 74 years. Evident neovascularization capacity, a significant tumor cell intracytoplasmic lumen frequently packed with red blood cells, and positive immunohistochemical reactions to endothelial antigens are of prime importance in making its diagnosis.

[The proliferative properties and regulators of the mitotic cell cycle of prostate adenocarcinoma].

The authors have made an immunohistochemical determination of Ki-67, topoisomerase IIalpha, cyclins D1, A, and B1, and calculated their indices in 145 acinar adenocarcinomas of the prostate. This tumor is characterized by a wide range of Ki-67 index (from 3 to 90% or more) although 90% of cases are in the range of 5-35%. Other study proliferative markers are distributed in the following descending order: cyclin D1 (1.

Use of a levonorgestrel-releasing intrauterine system to treat bleeding related to uterine leiomyomas.

Objective: This study was designed to evaluate the potential usefulness of the levonorgestrel-releasing intrauterine system (LNG IUS) in treating women with uterine leiomyomas.

Design: Prospective before-and-after study.

Setting: Family planning unit in an academic research institute.

[The structure of the chromatin at the syncytial stage in Drosophila melanogaster embryos].

Chromatin structure of D. melanogaster embryonic nuclei was studied at the stage of preblastoderm using the Miller method. Several levels of chromatin packing were detected after soft nuclei dispersion: individual or clustered compact spherical bodies 0.
