THE EFFECT OF EARLY FIBROBRONCHOSCOPIC SANITATION WITH HUMAN COLLAGEN TYPE 1 ON EPITHELIZATION OF DAMAGED TRACHEAL AND BRONCHIAL MUCOSA IN PATIENTS WITH INHALATION INJURY

Background. Inhalation trauma remains one of the most common and complex condition to be treated. Fibrobronchoscopic sanitation plays a significant role in the complex therapy of patients with inhalation trauma, allowing purulent necrotic discharge, soot and combustion products to be removed from the lumen of the tracheobronchial tree. We proposed a method for local treatment of mucosal lesions in inhalation trauma based on early endoscopic sanitation of the tracheobronchial tree with solutions of antiseptics followed by application of human type 1 collagen solution.Aim of study. To assess the effect of early fibroblochoscopic sanitation with application of human-type collagen 1 on the timing of epithelialization of the damaged tracheal and bronchial mucosa in patients with inhalation trauma.Material and methods. The study included 59 patients with inhalation trauma of 2–3 degree. All patients from the first day after the trauma underwent bronchoscopic sanitation in accordance with the standards of medical care. Immediately after the removal of soot, the solution of human-type collagen 1 was applied in patients of the main group, obtained from ligaments and tendons by the acid extraction method. The dynamics of the reparative process was evaluated on the basis of the endoscopic study and according to a series of morphological studies of the biopsy material obtained in the course of fibrobronchoscopy.Results. Complete epithelization of erosions of the mucous membrane of the trachea and bronchi in patients with inhalation trauma of 2 degree occurred significantly earlier (3 (2; 6) days) than without its application (7 (4; 9) day) (n1 =15; n2 =21; U=49.5; p=0.0004). In patients with inhalation trauma of 3 degree, epithelialization time was reduced from 17 (12; 22) days in the comparison group to 7 (6; 9) days in the main group (n1 =14; n2 =9; U=1; p=0.001). According to the morphological study, a characteristic feature of the fibrobronchoscopic sanitation with the human collagen type 1 was the absence of purulent inflammation of the trachea and bronchial wall.Conclusion. In the study, it was statistically proved that the early fibrobrochoscopic sanitation and application of the human collagen type 1 solution for acute lesions of the mucous membrane of the trachea and bronchi twice accelerates epithelialization of mucosal lesions without the development of purulent inflammation.

Abstract Background The aim of this study was the investigation of the osteogenic potential of human osteoblasts of advanced donor age in 2D and 3D culture. Methods Osteoblasts were induced to osteogenic differentiation and cultivated, using the same polystyrene material in 2D and 3D culture for 2 weeks. Samples were taken to evaluate alkaline phosphatase (ALP) activity, mineralization and gene expression. Results Osteoprotegerin (OPG) levels were significantly increased (8.2-fold) on day 7 in 3D compared to day 0 (p < 0.0001) and 11.6-fold higher in 3D than in 2D (p < 0.0001). Both culture systems showed reduced osteocalcin (OC) levels (2D 85% and 3D 50% of basic value). Collagen type 1 (Col1) expression was elevated in 3D on day 7 (1.4-fold; p = 0.009). Osteopontin (OP) expression showed 6.5-fold higher levels on day 7 (p = 0.002) in 3D than in 2D. Mineralization was significantly higher in 3D on day 14 (p = 0.0002). Conclusion Advanced donor age human primary osteoblasts reveal significantly higher gene expression levels of OPG, Col1 and OP in 3D than in monolayer. Therefore, it seems that a relatively high potential of bone formation in a natural 3D arrangement is presumably still present in osteoblasts of elderly people.

Various studies have been conducted to see the scaffold that supports the regeneration of tendon. This study aims to analyze thein vitrosecretome tenogenic potential produced by ASCs culture with fresh frozen tendon scaffold in hypoxic conditions. ELISA tests for Scx and IGF-1 levels in secretome were obtained from ASC culture with fresh frozen tendon scaffold under normoxic (21%) and hypoxia (2%) conditions. The immunohistochemical examination of COL-1 was also carried out on the 2ndand 6thdays of cell culture. The secretion of Scx and IGF-1 was increased in secretome from ASC cultures using a fresh frozen tendon scaffold compared with those which did not (p <0.05). In the normoxia condition, Scx and IGF-1 in secretome with fresh frozen tendons had better results than hypoxic conditions (p <0.05). The highest Scx levels were obtained in culture on the 6thday (p <0.05), while the highest IGF-1 levels were obtained in the culture on the 2ndday (p <0.05). There was an increase in the secretion of Scx and IGF-1 from ASC cultures with fresh frozen tendon scaffold under the hypoxic condition of 2%.

Abstract Background: Uterine leiomyomas (fibroids) are the most common benign estrogen-dependent tumors of premenopausal women. TGF-β3 up-regulates the synthesis of many of extracellular matrix proteins that are associated with tissue fibrosis. Objective: To examine the effect of 1,25-dihydroxyvitamin D3 (vitamin D3) on TGF-β3-induced fibrosis-related protein expression in immortalized human uterine leiomyoma (HuLM) cells. Methods: HuLM cells were treated with TGF-β3 with or without vitamin D3. Western blot analyses were employed to test the effect of vitamin D3 on TGF-β3-induced protein expression of collagen type 1, fibronectin, and plasminogen activator inhibitor-1 proteins. Western blots as well as immunofluorescence analyses were used to verify the effect of vitamin D3 on TGF-β3-induced Smad activation involved in extracellular matrix protein synthesis and deposition, which ultimately lead to tissue fibrosis. Results: We observed that TGF-β3 induced fibronectin and collagen type 1 protein expression in HuLM cells, and that effect was suppressed by vitamin D3. TGF-β3 also induced protein expression of plasminogen activator inhibitor-1, an important TGF-β target, in HuLM cells, which was also inhibited by vitamin D3. Additionally, TGF-β3 induced phosphorylation of Smad2 as well as nuclear translocation of Smad2 and Smad3 in HuLM cells, whereas vitamin D significantly reduced all these TGF-β3-mediated effects. Therefore, our results suggest that vitamin D3 has consistently reduced TGF-β3 effects that are involved in the process of fibrosis in human leiomyoma cells. Conclusion: Vitamin D3 is an antifibrotic factor that might be potentially useful as a novel therapeutic for nonsurgical treatment of benign uterine fibroids.

Although elevated levels of homocysteine (Hcy) known as hyperhomocysteinemia (HHcy) are associated with increased inflammation and vascular remodeling, the mechanism of Hcy-mediated inflammation and vascular remodeling is unclear. The matrix metalloproteinases (MMPs) and adhesion molecules play an important role in vascular remodeling. We hypothesized that HHcy induces inflammation by increasing adhesion molecules and matrix protein expression. Endothelial cells were supplemented with high methionine, and Hcy accumulation was measured by HPLC. Nitric oxide (NO) bioavailability was detected by a NO probe. The protein expression was measured by Western blot analysis. MMP-9 activity was detected by gelatin-gel zymography. We demonstrated that methionine supplement promoted upregulation of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) through increased Hcy accumulation. In addition, increased synthesis of collagen type-1 was also observed. MMP-9 gene expression and protein activity were increased in methionine supplement groups. 3-Deazaadenosine (DZA), an adenosine analogue, prevented high methionine-induced ICAM-1 and VCAM-1 expression and collagen type-1 synthesis. Transfection of endothelial cells with cystathionine-β-synthase (CBS) gene construct, which converts Hcy to cystathionine, reduced Hcy accumulation in high methionine-fed cells. CBS gene transfection reduced the inflammatory response, as evident by attenuated ICAM-1 and VCAM-1 expression. Furthermore, collagen type-1 expression and MMP-9 activity were dramatically attenuated with CBS gene transfection. These results suggested that methionine supplement increased Hcy accumulation, which was associated with inflammatory response and matrix remodeling such as collagen type-1 synthesis and MMP-9 activity. However, in vitro DZA and CBS gene therapy successfully treated the HHcy-induced inflammatory reaction in the methionine metabolism pathway.
