In this study, we have investigated the effects of repeated inhalation SS welding dust (WD) and its soluble form (SWD) on club (Clara) cells in the bronchiolar epithelium and Clara cell protein (CC16) in rats and inquired whether the nuclear factor-kappa B (NF-[kappa]B) and or c-Jun/AP-1 related pathways were involved.
To validate the relevance between TAZ expression and treatment response in NSIP, we also compared TAZ expression in fibroblasts, bronchiolar cells, and alveolar cells between the good response and nonresponse groups.
The entrapped bronchiolar epithelium was highlighted by AE1/AE3 (i) (arrow) (immunoperoxidase; original magnification: (c, d, g, and i) x100; (a, b, e, f, and h) x200).
total) terminal bronchiolar epithelial cells ([V.sub.v]) was measured for all treatment groups (Table 2).
Caption: Figure 2: The lymphocytes infiltrated bronchiolar epithelium forming well-defined lymphoepithelial lesions.
The location of the lesion is also in the periphery of the lung, while this type of lung cancer usually arises centrally with hilar vessel and bronchiolar invasion.
Proliferation of smooth muscle cells along the peribronchiolar lymphatics leads to bronchiolar obstruction and formation of lung cysts [11] (see Figure 1).
With regard to lower airways, the prevalence of bronchiolar involvement ranges from less than 10% to over 60% [17] and it can present as follicular bronchiolitis or constrictive bronchiolitis obliterans.
Histological changes in the lung revealed degenerative changes in the bronchiolar epithelium while damaged endothelial cells were observed.
The third is about the high levels of prostaglandins during the menstrual period, these high levels cause vascular and bronchiolar vasoconstriction.
CPAP maintains positive pressure in the airways in spontaneously breathing patients during both phases of respiration, improves alveolar ventilation and oxygenation by increasing functional residual capacity, decreases pulmonary edema, minimizes expiratory bronchiolar collapse, decreases intrapulmonary shunting, lowers upper airway resistance, stimulates lung growth, conserves surfactant, increases lung compliance and reduces obstructive apnea14.
Granulocyte macrophagecolony-stimulating factor is found in early PLCH granulomas and in bronchiolar epithelial remnants in stellate lesions, suggesting its role in airway Langerhans cells expansion.
There are certain pathological changes such as lungs show diffuse alveolar damage, bronchiolar congestion, and interstitial oedema.
Moreover, varying degrees of mononuclear cells inflammation of the bronchiolar walls involvement have been noticed (Figures 5-6).
