“…In contrast to the protective role of HA in lung physiology, it has also been reported that: serum levels of HA did not differ between patients with asthma or wheeze compared with normal controls [37]; inhaled low molecular mass HA (0.15610 6 kDa) did not significantly protect against exerciseinduced bronchoconstriction in asthmatic patients [38]; and there are increased levels of HA in lung secretions of asthma [39] and COPD [13] patients. However, these apparently contradictory reports may be explained as follows: 1) HA serum levels may not necessarily reflect HA levels in the lung; 2) it is the high molecular mass HA that exerts beneficiary effects; 3) lower molecular mass HA (0.3-0.5610 6 kDa) predominate under inflammatory conditions [14]; 4) the increased levels of HA in lung secretions of asthma and COPD patients may reflect enhanced degradation and subsequent secreation of HA, as a consequence of the increased expression of Hyal2 in COPD patients [13] and Hyal1 in ASMC that we report here.…”

“…Hyaluronic acid (HA) is a polysaccharide present in human tissues; inhaled HA has been tested not only in CF but also in asthma 6. HA blocks acute bronchoconstriction caused by neutrophil elastase7 and, regulating fluid balance in the lung interstitium, facilitates ventilation and gas exchange.…”

“…ГК -компонент внеклеточного матрикса, является высокомолекулярным гликоза миногликаном, который состоит из повторяющихся дисахаридов N ацетилглюкозамина и глюкуроновой кислоты. Интересные исследования по применению ГК проведены не только при МВ, но и при брон хиальной астме, и при эмфиземе легких [47][48][49]. На мышиных моделях МВ получено снижение ле гочного воспаления после 3 дней ингаляционного введения ГРХН [50].…”
