Histopathological findings of intrafascicular-edema found in n. ulnaris running at forearm, palmside of hand and fingers of rhesus monkey 8664 and african green monkey 8175 were studied by semithin section method. These two monkeys were inoculated with leprosy bacilli from lepromata of mangabey monkey A022. The mangabey monkey A022 had been experimental leprosy after inoculum of the leprosy bacilli from lepromata of the mangabey monkey A015-natural infection. Period between date of inoculum and sacrifice of the rhesus monkey 8664 was about 2 years, and the african green monkey 8175 was about 5 years. Results found were: 1. Intrafascicular-edema found in n. ulnaris running at forearm, palmside of hand and fingers was remarkable at some of peculiar anatomical areas where were put on mechanical pressure. 2. The intrafascicular-edema inside many fascicles was remarkable around the small blood vessels. 3. Obsruction of the small blood vessels and congestion of blood stream at surrounded of the intrafascicular-edema with fibrous elements and cellular elements were observed inside some of fascicles. 4. Bundles of peripheral nerve fibers inside some of fascicles were pressed by the intrafascicular-edema, and the fibrous elements, especially collagen fibers, were increased around the pressed bundles of nerve fibers and each nerve fiber inside the fascicles. 5. Vacuolar degeneration and swelling of axon were observed at some of myelinated nerve fibers. 6. Not only the intrafascicular-edema but also a large amount of intracytoplasmic foamy structures with solid leprosy bacilli were observed inside many fascicles.(ABSTRACT TRUNCATED AT 250 WORDS)
