title: Electrophysiological and histopathological changes in peripheral nerves of postnatally undernourished and rehabilitated young rhesus monkeys.
abstract: Nerve condition velocity of ulnar and tibial nerves and qualitative histology of ulnar nerve were studied in young rhesus monkeys. Motor nerve condition velocity of both the nerves and amplitude of sensory response of ulnar nerve were significantly decreased in even moderate protein calorie malnourished (PCM) group of monkeys. Increased paranodal gap, segmental demyelination, thin myelinated fibres and prominent Schmidt Lanterman Clefts were also observed in PCM group. There was complete recovery in motor nerve conduction velocity in the nerves of both limbs while partial in amplitude of sensory response in proximal segment of ulnar nerve on nutritional rehabilitation of 10-12 weeks.
