[Candidates for virulence factors of Aspergillus fumigatus].

The number of patients with invasive fungal infection (IFI) has dramatically increased since the beginning of the 1980s. Aspergillus fumigatus, the most common species recovered from aspergillosis, is an important pathogen of IFI. Recently, new antifungal agents have become available in Japan, but mortality from aspergillosis is still high.

Gene expression profiling of polymorphonuclear leukocytes treated with the culture filtrate of Aspergillus fumigatus and gliotoxin.

Pathogens of the Aspergillus species are frequently seen in deep-seated mycoses. We previously demonstrated that the culture filtrate of Aspergillus fumigatus (CF) has immunosuppressive effects on polymorphonuclear leukocytes (PMNs), which act as the main phagocytes to hyphae of Aspergillus fumigatus (A. fumigatus).

Cytotoxic substances from Aspergillus fumigatus in oxygenated or poorly oxygenated environment.

Aspergillus fumigatus often causes serious health problems. The airway of the human body, the most common initial site of damage, is always exposed to an oxygenated condition, and the oxygen concentration may play a critical role in the virulence of A. fumigatus.

[A study on low performance status cases of pulmonary tuberculosis in the elderly].

The subjects consisted of 42 patients aged over 60 years, whose performance status (PS) was grade 3 or 4, and who had been admitted for pulmonary tuberculosis at National Chiba-Higashi Hospital between 1997 and 1998. The average age (+/- SD) of the 34 men and 8 women was 77.6 (+/- 8.

[A case of perforative peritonitis complicated with lung and intestinal severe tuberculosis].

A 27-year-old man was admitted to our hospital in September 18, 2000, complaining of fever, cough, appetite loss and body weight loss. He was diagnosed as advanced lung tuberculosis, because of chest X-ray findings and positive acid-fast bacilli in his sputum. He was administrated rifampicin (RFP), isoniazid (INH) and ethambutol (EB).
