Altered capillary permeability Vasoactive peptides play a multifaceted and often paradoxical role in the complex aftermath of burns. While some vasoactive substances can exacerbate inflammation and edema, others demonstrate therapeutic potential in modulating the body's response to severe thermal injury.The Role of Vasoactive Intestinal Peptide and Mast Cells in ... Understanding these peptides is crucial for developing effective burn management strategies, particularly in areas like acute burn shock resuscitation.

One of the most extensively studied vasoactive peptides in the context of burns is vasoactive intestinal peptide (VIP)Vasoactive intestinal peptide: cardiovascular effects - PubMed. Research by Lindblom and colleagues in 2000 highlighted that while VIP is a potent vasodilator and increases blood flow in various tissues, its role in burns is nuanced.作者：G Onuoha·2001·被引用次数：31—Trauma and humanburninjuries are associated with increase levels of NO productions. While VIP rose in trauma, it remained unchanged inburns. The relationship between VIP and NO observed under physiological conditions in thermal and trauma injury may be of ... Initially, it was suggested that VIP might not directly affect capillary permeability. However, further investigations indicated that systemic VIP is a potent inhibitor of burn oedema.作者：G Onuoha·2001·被引用次数：31—Trauma and humanburninjuries are associated with increase levels of NO productions. While VIP rose in trauma, it remained unchanged inburns. The relationship between VIP and NO observed under physiological conditions in thermal and trauma injury may be of ... This inhibitory effect could be attributed to a secondary constriction of skin vessels. Studies have also explored the concentration of vasoactive intestinal polypeptide in severely burned patients, with findings suggesting its involvement in the metabolic and hormonal responses that contribute to the hypercatabolic state following severe burns.

The interplay between vasoactive intestinal peptide and nitric oxide (NO) in the acute phase following burns and trauma is another area of significant interest作者：K DeSpain·2021·被引用次数：4—We hypothesize that severeburnsdisturb arterial contractility through acute changes in adrenergic and cholinergic receptor function.. While trauma is associated with increased NO production, VIP levels have been observed to remain unchanged in burns, suggesting a different regulatory mechanism compared to other forms of injury.作者：MD Frame·2017·被引用次数：3—Blood vessel plugging in periburn tissue is secondary to erythrocyte aggregation and mitigated by a fibronectin-derivedpeptidethat limitsburn... This relationship between VIP and NO under physiological conditions in thermal and trauma injury warrants further investigation.

Beyond VIP, the pathophysiology of burns involves the release of various vasoactive peptides from damaged tissues. These substances can contribute to altered capillary permeability, leading to the characteristic edema seen in burn wounds. The release of these peptides is a direct consequence of the coagulation necrosis of skin and tissuesEffect of vasoactive intestinal peptide on the wound healing of .... Furthermore, research into specific peptide compounds, such as EVA- 1, has shown promise.Treatment Strategies in Burn Wounds: An Overview EVA- 1 ameliorates thermal burn injury progression and has been found to bind to and enhance platelet-derived growth factor (PDGF)-BB, promoting cell metabolism, growth, and survival. This suggests targeted peptide-based interventions could be beneficial.

The potential for vasoactive agents in burn patients extends to wound healing. For instance, studies have shown that VIP has positive effects on alkali induced corneal burns. This effect is thought to be mediated by VIP inhibiting polymorphonuclear leukocyte (PMNL) migration to the cornea through an immunomodulatory effect.作者：L Lindblom·2000·被引用次数：11—Vasoactiveintestinal polypeptide is one of the body's most potent vasodilators and has been shown to increase blood flow in a number of tissues. This finding opens avenues for exploring VIP's role in promoting healing in specific types of burn injuries.

It's important to differentiate the roles of various vasoactive substances. While vasoactive intestinal polypeptide is more potent than prostaglandin E2 as a vasodilator and edema potentiator in rabbit skin, its overall impact in burn wounds is complex and context-dependent作者：L Lindblom·2000·被引用次数：12—The present results show thatsystemic VIP is a potent inhibitor of burn oedema. This effect could be secondary to constriction of skin vessels as a result of .... The NCI Dictionary of Cancer Terms defines vasoactive intestinal peptide as a neuropeptide with diverse physiological functions, including its role in regulating blood flow and inflammation1 and related peptides in quiescent and stress model.

The broader implications of vasoactive peptides in burns also touch upon conditions like post-burn pruritus, where neuropeptides secreted from skin nerves play a role in controlling epidermal and vascular proliferationVasoactive intestinal peptide and nitric oxide in the acute .... Understanding these signaling pathways is crucial for managing the long-term sequelae of burns.

In summary, the study of vasoactive peptides in burns reveals a complex biological landscape.Role of vasoactive intestinal polypeptide in burn-induced ... While the initial injury triggers the release of inflammatory mediators, including certain vasoactive peptides, specific peptides like VIP demonstrate a potential to mitigate edema and promote healing. Continued research into these vasoactive agents is vital for advancing the understanding and treatment of burns, from immediate resuscitation to long-term recovery.作者：L Lindblom·2000·被引用次数：11—Vasoactiveintestinal polypeptide is one of the body's most potent vasodilators and has been shown to increase blood flow in a number of tissues. The exploration of Vasoactive intestinal peptide and nitric oxide (NO), alongside novel peptide therapeutics, offers promising avenues for improving patient outcomes.
