Mucus secretion from individual submucosal glands of the ferret trachea.
Mucus secretion from individual tracheal glands in adult ferrets was studied with time-lapse optical imaging of mucus droplets under an oil layer. Density of functional glands (determined by responses to 1 muM carbachol) was 1.5 +/- 0.3 per mm(2) (n = 6). Secretion rates (in pl.min(-1).gland(-1)) were as follows: 4.1 +/- 0.7 basal (unstimulated; n = 27, 669 glands), 338 +/- 70 to 10 microM fors...
متن کاملVasoactive intestinal peptide stimulates mucus secretion, but nitric oxide has no effect on mucus secretion in the ferret trachea.
Vasoactive intestinal peptide (VIP) and nitric oxide (NO) are neurotransmitters involved in the regulation of bronchial and pulmonary vascular tone. Published studies of the effects of VIP on airway mucus secretion have yielded conflicting results. The purpose of this study was to determine the effect of VIP on mucus secretion in the ferret trachea and if this effect was influenced by NO. We us...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولMucus transportability: the bovine trachea and frog palate models compared.
For nearly 30 yrs, the mucus-depleted frog palate has been used to measure the ciliary transportability of respiratory and other mucus gels, but the data obtained from this amphibian digestive system may not be applicable to human airway mucociliary clearance. This study compared this model with the mucus-depleted bovine trachea, a mammalian respiratory system. Assessments were made of the repr...
متن کاملTemperature, humidity and mucus flow in the intubated trachea.
Mucus flow rates were measured in the intact trachea of anaesthetized dogs, using a radioactive tracer technique. Measurements were made before intubation, and after intubation at inspired air temperatures of 32, 37 and 42°C, with a constant inspired water vapour content of 33 mg/1.; and again at each temperature with a relative humidity of 75%. No significant difference in mucus flow rate was ...
