The Role of Oral Organs in Local Immunity with Elements of Morphology of Lingual Glands.

In postnatal ontogeny, the topographic relationships of the tongue glands and lymphoid structures in the thickness of the tongue have clear age-related features. In this article, we discuss the features of the glandular-lymphoid relationship in the thickness of the tongue, which is of particular scientific and practical importance for more precise understanding of the mechanisms providing local immunity in the oral cavity.

[The results of an open observational study on multimodal effects of the efficacy and safety of supplement neurouridine in patients with nonspecific low back pain (MULTINEURO-1)]. / Rezul'taty otkrytogo nablyudatel'nogo issledovaniya po otsenke mul'timodal'nykh effektov i bezopasnosti biologicheski aktivnoi dobavki Neirouridin u patsientov s nespetsificheskoi bol'yu v spine (MUL''TINEIRO-1).

OBJECTIVE: The article presents the results of the first observational study in the Russian Federation on the efficacy and safety of high doses of uridine monophosphate (150 mg) in combination with choline (the supplement neurouridine) in the treatment of patients with nonspecific low back pain. MATERIAL AND METHODS: The Visual Analogue scale (VAS), the painDETECT questionnaire (PD-Q), the Roland-Morris Low Back Pain and Disability Questionnaire, the Hospital Anxiety and Depression Scale (HADS) and the Pittsburgh Sleep Quality Index were used to assess the efficacy of neurouridin in 50 patients with lower back pain. RESULTS AND CONCLUSION: A conclusion was also made about a greater decrease in the intensity of pain in the main group than in the comparison group, a positive effect of treatment on a decrease in the severity of the neuropathic component of pain was not- ed according to the results of PD-Q, revealing signs of improved functional status according to the analysis of the Roland-Morris low back pain and disability questionnaire.

Age-Associated Role of Lingual and Pharyngeal Glands in Local Immunity in Oral Cavity.

The macroscopic and histological methods were employed to examine the autopsy specimens of salivary lingual glands obtained from 299 patients of both sexes and various age ranging from newborn to longevity. The age-associated alterations of minor lingual and pharyngeal glands were revealed, and the topographical relations between the glands and lymphoid cells were described. The characteristic sparsity of the glands in infancy is caused by nutritional uniformity at this period, when diminished production of secretory IgA results in frequent inflammatory processes in oral and pharyngeal cavities. With age, the glandular orifices widen, and their number increases thereby augmenting local immunity in the oral cavity and in oral aspect of the pharynx. Starting from elderly and senile age, the involutive alterations were observed, which were accompanied by diminished production of secretory immunoglobulin A and related degradation of local and humoral immunity.
