健康人体对真菌具有较强的抵抗力,在某些条件真菌可进入肺部并引起肺部真菌感染,真菌多在土壤生长,孢子飞扬,从空气中可吸入肺部造成外源性感染。正常人的口腔上呼吸道内寄生着大量霉菌,当机体抵抗力下降时,这些霉菌则乘虚而入,造成内源性感染。随着广谱抗生素和激素的广泛应用,其发病率也日益增多。1997年1月至1999年1月我院收治慢性肺心病274人,符合支气管—肺部真菌感染者28例,现分析如下:
Healthy humans have strong resistance to fungi. In some conditions, fungi can enter the lungs and cause fungal infections of the lungs. Fungi grow more in the soil and the spores fly high and can inhale the lungs from the air and cause exogenous infections. Normal oral cavity parasites with a large number of mold, when the body resistance decreased, these molds take advantage of, resulting in endogenous infections. With the widespread use of broad-spectrum antibiotics and hormones, the incidence is also increasing. January 1997 to January 1999 admitted to our hospital in 274 cases of chronic pulmonary heart disease, bronchial-pulmonary fungal infection in line with 28 cases, are analyzed as follows:
