gen. nov., sp. nov., isolated from the junction between the ocean and a freshwater lake.

A Gram-stain-negative, non-flagellated, non-gliding, aerobic and rod-shaped bacterium, designated HJM-3, was isolated from the place where the ocean and a freshwater lake meet at Hwajinpo on the East Sea, South Korea, and subjected to a polyphasic taxonomic study. The novel strain grew optimally at 30-35 °C, at pH 7.0-7.

Melanosis ilei induced by prolonged charcoal ingestion.

Gastrointestinal melanosis is observed most frequently in the colon it also can develop in the ileum, duodenum and esophagus very rarely. Melanosis ilei was thought that causative materials such as aluminum, magnesium, silicate, titanium and other compounds entered the body through the ingestion of agents. We experienced a case of melanosis in the terminal ileum that a 65-year-old female patient ingested 10 g edible charcoal everyday for 3 years to address symptoms of chronic abdominal pain.

Four cases of non-Hodgkin's lymphoma in AIDS patients.

The incidence of opportunistic infection has decreased since the introduction of highly active antiretroviral therapy, so lymphoma is now far and away the most lethal complication of acquired immunodeficiency syndrome. We have experienced four cases of NHL in AIDS patients. The first patient was a 37 year old male who presented with left sided hemiplegia due to CNS lymphoma.
