Effects of amnion and live yeast cell derivative on second-intention healing in horses.
Abstract: Equine amnion and live yeast cell derivative were evaluated as a biological dressing and as a topical wound medicament respectively, in the treatment of granulating wounds of the distal portion of the limbs of horses. Wounds measuring 2.5 x 2.5 cm were created on the dorsomedial aspect of the metacarpal and metatarsal region of all 4 limbs of 9 horses. Each wound was assigned randomly to 1 of 3 treatment groups: group C, treated with a nonadherent bandage as a control; group A, treated with amnion beneath a nonadherent bandage; and group L, treated with live yeast cell derivative beneath a nonadherent bandage. Rates of contraction and epithelialization were not significantly different among groups. Percentage of epithelialization for group A was significantly greater throughout the study than for the other groups. Number of days to complete healing was significantly less in group A and significantly greater in group L than in group C. Incidence and severity of exuberant granulation tissue were significantly less in group A than in the other 2 groups. Group L had more frequent and severe cases of exuberant granulation tissue than the other 2 groups.

The research article investigates the effects of horse amnion and live yeast cell derivative on the healing process of wounds on horses’ lower limbs. The article reveals that using horse amnion showed sped up healing and a lower incidence of overgrowth of granulation tissue.
Experimental Design
- The researchers created controlled wounds of size 2.5 x 2.5 cm on the dorsomedial aspect of the legs of nine horses, ensuring that each horse had a wound on all four legs.
- These wounds were randomly assigned to three different treatment groups: Control group (C), Amnion group (A), and Live yeast cell derivative group (L).
- The control group got treated with a nonadherent bandage. The Amnion group had the amnion beneath a nonadherant bandage while the live yeast cell derivative group was bandaged with the yeast derivative beneath a nonadherent bandage.
Outcome Measures
- Key metrics: the percentage of closed wound surface (epithelialization), resultant scar and overall healing days, appearance, and severity of extra granulation tissue (growth of new tiny blood vessels).
- The comparisons were made among all treatment groups to figure out the best technique.
Findings
- The results showed no considerable difference in wound contraction and epithelialization rates among all groups; however, the percentage of epithelialization was significantly higher in the amnion group throughout the study.
- Amnion group had a significantly lower healing time as compared to the control group.
- Notably, the amnion treatment also led to lower instances and severities of exuberant granulation tissue (hypergranulation), which can impede the healing process. In contrast, the group treated with live yeast cell derivative experienced a higher rate of such tissue formation, which may have resulted in a comparatively more extended healing period.
- Overall, it indicates that the application of amnion as a biological dressing can potentially enhance the healing of wounds in horses.
