The examination of biophysical skin parameters (transepidermal water loss, skin hydration and pH value) in different body regions in Polish ponies.

This study examined the transepidermal water loss (how much water the skin loses), skin hydration levels, and skin pH values in different body regions of Polish ponies. The aim was to establish normal values for these skin properties to aid in future health assessments of these animals.

About the study

• The study employed twelve Polish ponies of both sexes.
• Seven different body regions (including the neck, shoulder, thorax, lumbar, inguinal, lip region and the pinna) were focused on for the measurements.
• The biophysical skin parameters measured included transepidermal water loss (TEWL), skin hydration, and skin pH levels.

Results and Findings

• For transepidermal water loss (TEWL), the findings indicated the lowest values in the pinna (the outer part of the ear) with 10.54 g/hm(2)), and the highest values in the lip region with 30.98 g/hm(2)). This suggests that more water is lost through the skin in the lip area compared to the pinna.
• When it came to skin hydration, the thorax region (the area including the chest and the cavities containing the organs such as the heart and lungs) exhibited the lowest values (1.96 CU), while the lip region showed the highest (48.28 CU). This hints that the skin of the lip area retains more water than the thorax region.
• In terms of skin pH (which indicates the level of acidity or alkalinity), the lowest results were obtained in the pinna (7.03), indicating a more neutral pH, and the highest in the lumbar region (the lower back) with a slightly alkaline pH of 8.05.

Importance of the study

• This study contributes to a better understanding of the normal skin physiology of Polish ponies.
• The established values for the skin parameters can be used as references for future health assessments and studies related to skin issues in these animals.
• Furthermore, the recorded differences in skin parameters between different body regions may aid in pinpointing potential problem areas and in developing treatment strategies in instances of dermatological issues.
