Oxidative Cyclisation

A novel intermolecular dearomative [4 + 2] annulation of 3-nitroindoles and enals under oxidative N-heterocyclic carbene catalysis has been developed. This protocol was also suitable for the oxidative cyclisation of 2-nitrobenzothiophenes with enals.

The objective: the study of immunomodulatory effects of a probiotic, which contains lyophilized Lactobacillus (Lactobacillus rhamnosus) – 13 mg (2,0ґ109 CFU) and lyophilized bifidobacteria (Bifidobacterium lactis) – 4 mg (2,0ґ109 CFU) the level of serum immunoglobulin IgA as a marker of local immunity in the plasma of women of reproductive age with the violation of the biocenosis of the vagina. Patients and methods. The study involved 86 patients of reproductive age with the violation of the vaginal biocenosis, which were divided into two groups according to received treatment. A survey was conducted for all patients in both groups: determine the level of serum IgA, measuring pH of vaginal environment and the quantification of lactobacilli and pathogenic flora with the help of test-system «Florotsenoz» before treatment and in 6 weeks after treatment. The state of vaginal microbiocenosis in both groups before treatment was homogeneous. Patients in both groups as therapy at the first stage of treatment received, if necessary antimicrobial therapy depending on the selected flora. In the second stage (restoration of microflora) patient of the main group received systemic probiotic combined with a complex prebiotic local action, patients in the control group, the probiotic localy in the form of the vaginal candles or tablets. Results. The research stated the increasing level of serum IgA in blood plasma of patients of the main group compared to control group at 20%, normalizing the pH of the vaginal environment in the main group in 94% of cases, which indicates an increase of immunity in mucosal. Conclusion. The inclusion of the systemic probiotic in the scheme of treatment of disorders of biocenosis of the vagina system enhances the increasing of immunity of the mucous membranes, and the vaginal tablets prebiotic of local action restores the own normal microflora of the vagina. Key words: serum immunoglobulin A, local immunity, vaginal dysbiosis, probiotics, prebiotics, vaginal microbiocenosis, the pH of the vaginal environment.

The Moment

Irritable bowel syndrome is a frequent digestive condition, with an unclear etiopathogeny. Very probably intestinal dysbiosis plays an important role. For the moment there are no guidelines for treatment. There is scientific evidence for several therapies: modification of diet, non-resorbable antibiotics (rifaximin-α) and probiotics. Giving probiotics after each antibiotic course (an association of Bifidobacterium longum BB536 and Lactobacillus rhamnosus HN001) supplemented with vitamin B6 may be an optimal strategy.
