The number of viral infection cases in the Department of Gynecology and Obstetrics has tended to increase over last few years. Viruses form herpesvirus and cytomegalovirus families are associated with an increased risk for recurrent pregnancy loss. Photodynamic therapy (PDT) is a promising new approach to treat viral infections in which viral particles are inactivated. It exhibits great therapeutic potential, particularly among this group of patients. This study examined the use of PDT to treat herpesvirus infection (HVI) using an in vitro model. In this study, we used the Vero сell lineage as a suitable model of HVI, strains of HSV-1 (strain VR-3) and HSV-2 (strain MS) obtained from The National Virus Collection (London, UK), the photosensitizer Fotoditazine (Veta-Grand, Russia), an AFS physiotherapeutic device (Polironic Corporation, Russia). Laser light irradiation and the photosensitizer had different cytotoxic effects on the Vero cell cultures depending on the doses used. The optimal laser light and photosensitizer doses were determined. PDT had an antiviral effect on an in vitro model of HVI in cell culture. PDT has been shown to be effective treatment for HVI in vitro, leading to a reliable decrease of viral titer.
Insufficient nutrition is an urgent problem of modern healthcare. According to WHO, more than 2 billion people suffer from essential vitamin and mineral deficiencies, in particular vitamin A, iodine, iron and zinc [1]. The hypovitaminosis, as well as hypoelementosis pose the greatest threat to pregnancy and lactation, contributing to the development of miscarriages, intrauterine growth restriction, maternal mortality, labor complications, infectious pathology and adverse course of the neonatal period.Objective of the study: evaluation of the efficacy of the vitamin and mineral complex in correcting the nutritional status of patients during gestation.Materials and methods of the study: 33 pregnant women with threatened miscarriage of various genesis, who were admitted to the department of gynaecology, underwent a clinical and laboratory examination and treatment. In addition to the general clinical examination, all patients were assessed for plasma vitamin E and folic acid concentrations, which play a key role in embryogenesis. In addition to therapy aimed at prolonging pregnancy, all pregnant women received nutritional support in the form of a multivitamin drug.Results of the study: During the observation period, the condition of pregnant women improved significantly: signs of threatened miscarriage were eliminated, complaints of weakness, fatigue and sleep disturbance disappeared. All patients showed significantly higher plasma vitamin E and folic acid concentrations after the treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
