Colonoscopy was performed on acute stage within 72 hours from onset in 48 patients with antibiotic-associated hemorrhagic colitis (AAHC). From our observations we have developed a new endoscopic classification of AAHC and investigated the incidence of each finding in further detail. We have classified in principle the endoscopic findings of the 48 subjects into two groups: major and minor ones respectively. Category of major findings were: 1) diffuse mucosal hemorrhage (100%); 2) spotty mucosal hemorrhage (100%), and 3) linear mucosal hemorrhage (22.9%) w, hile minor findings were: 1) irregular ulcers in 10.4%; 2) aphthoid ulcers in 6.3%, a nd 3) linear erosions or ulcers in 4%. Minor findings were ulcers or erosions present over the hemorrhagic mucosa associated with the moderate degree of inflammation. A histopathologic study of colon biopsy specimens from 24 patients with AAHC showed hemorrhage and inflammatory cell infiltration in the lamina propria mucosae varing from mild to moderate in extent. It was concluded that AAHC was a colonic mucosal hemorrhagic disease caused by the destruction of mucosal vessels from unknown causes and in this disease mild to moderate inflammation was partially followed by ulceration over the edematous and hemorrhagic mucosa of the colon.

The effects of partial obstruction of blood flow and mixed type acidosis on the conduction spinal evoked potentials (C-SEP) were studied in cats anaesthetized with sodium pentobarbitone and immobilized with d-tubocurarine. Following the ligation of some intercostal arteries, changes in the C-SEP occurred: the amplitudes showed either an increase or a decrease, while the latencies were uniformly prolonged. Mixed-type acidosis resulting from a decrease in the respiratory minute volume led to a decrease in the amplitudes and an increase in the latencies.
The above findings indicate that not only mechanical (obstruction of the blood blow) but also metabolic (mixed-type) factors lead to changes in the C-SEP. It is therefore important to take these factors into account and the waveform of the C-SEP should be interpreted in terms of amplitude and latency.

Enterovesical fistula caused by inflammatory bowel diseases is a rare disorder. Two male patients with recurrent cystitis had sigmoid colon diverticulitis causing enterovesical fistula. One female patient with Crohn's disease developed enterovesical fistula with abdominal and urinary symptoms. In each patient, a barium enema revealed causative bowel diseases. The precise diagnosis of enterovesical fistula was made either by cystography or cystoscopy. One-stage resection of the inflamed bowel with fistula and affected the bladder wall was proved to be an effective treatment for these three patients, while a long term follow up is specifically necessary in the patient with Crohn's disease.
