[Developmental mechanism of the "lung ball"--with reference to the pathological findings of the lung in two resected cases].

The lung ball is a special type of pulmonary aspergillosis (PA) occurring often after chemotherapy for leukemia. Histologically the ball, with air crescent sign on roentgenogram, is compatible with necrotizing lung tissue admixed with Aspergilli. The lung ball differs entirely from the common "fungus ball" in its quality, though they are similar in roentgenological appearances.

The genome sequence of the plant pathogen Xylella fastidiosa. The Xylella fastidiosa Consortium of the Organization for Nucleotide Sequencing and Analysis.

Xylella fastidiosa is a fastidious, xylem-limited bacterium that causes a range of economically important plant diseases. Here we report the complete genome sequence of X. fastidiosa clone 9a5c, which causes citrus variegated chlorosis--a serious disease of orange trees.

The administration of medical records in Japanese hospitals: a status report.

We performed the nation-level investigation, the aim of which is to grasp the present status of the administration of medical records in Japanese hospitals. There have been conducted such few investigations as this one yet in Japan. We made a report of the administration of medical records, the use of medical records, and the use of advanced tools like microfilms, computers, broken down by some attributes like establishments and bed sizes.
