Neuronal Recovery

Restoration of impaired function follows structural recovery, as well as other mechanisms that have been described in recovering neural tissue. Among them are adaptive responses, also called neuronal plasticity, that incorporate the following processes:

Rapid responses, where uninjured neurons assume the function of damaged neurons. This process of unmasking has been demonstrated in PET scans, showing increased cerebral blood flow and metabolism in uninjured areas of brain [8]. Re-learning or long-term potentiation (LTP), which takes place by activity-dependent changes in synaptic efficacy. This influences information storage mediated by neurotransmitters such as NMDA, which facilitates LTP, and GABA, which inhibits LTP. Such phenomena have been seen in the hippocampus and visual cortex [9]. Slow adaptive responses, which consist of rearrangements where several hypothetical models have been proposed [10]:

- Regeneration after axonal damage, with possible regrowth of axons that innervate the target organs [11].

- Pruning, seen in neurons with many axons. When one axon is damaged, other collateral axons innervate the target organs. The evidence for this is more definite in human brains than in hamster brain [12].

- Collateral sprouting, which is the most evident change, consists of outgrowth of axons from undamaged adjacent cells to innervate target organs, forming functioning units [10].

- In-growth, where uninjured neurons from remote areas innervate a target organ. This is commonly observed with injury to sympathetic nerves with the possible consequence of abnormal function [13].

The term vaginitis is one that is applied to any inflammation or infection of the vagina, and there are many different conditions that are categorized together under this ‘broad’ heading, including bacterial vaginosis, trichomoniasis and non-infectious vaginitis.
