“…Measuring TEWL in different body regions (skin mapping) has been performed in dogs, cats and horses and it was found that, similarly to examinations in humans, TEWL values differ according to body region under investigation (Oh and Oh 2009b, Szczepanik et al 2011, 2012, Momota et al 2013.

Non-invasive methods of skin condition assessment include, among others, the evaluation of transepidermal water loss (TEWL). The aim of the study was to examine whether TEWL values depend on horse breed. The study was conducted on four breeds: "Felin" ponies (FP) (n=16), Polish koniks (PK) (n=15), Polish cold-blooded horses (PcbH) (n=11) and Wielkopolska horses (WH) (n=12). It was found that horse breed influences TEWL values. In the neck region, statistically significant differences were found between PK and FP (p=0.006), and PK and WH (p=0.0005). In the lumbar region, there were statistically significant differences between FP and PK (p=0.0009), FP and PcbH (p=0.0016) as well as between PK and WH (p=0.000037), and PcbH and WH (p=0.0006). In the inguinal region statistically significant differences were found between FP and PK (p=0.0003), FP and PcbH (p=0.0005), PK and WH (p=0.009) and PcbH and WH (p=0.006). In the lip region statistically significant differences were observed between FP and PK (p=0.013) as well as between PK and PcbH (p=0.029) and PK and WH (p=0.009). In the examination of TEWL animal breed should be taken into consideration. The non-significant differences found in three of the examined body regions may suggest that these regions are the most adequate for TEWL assessment.

“…Recently, much research involving the assessment of skin biophysical parameters has been published (Dirschka et al 2005, Fluhr et al 2006, Hightower et al 2008, Oh and Oh 2009, Cornegliani et al 2011. Much attention has been given to the assessment of these parameters in dogs (Beco et al 2000, Matousek et al 2002, Watson et al 2002, Young et al 2002, Hester et al 2004, Yoshihara et al 2004, Oh and Oh 2009, Shimada et al 2009, Hightower et al 2010, Lau-Gillard et al 2010, Ohmori et al 2010, Cornegliani et al 2011, Marshala 2012. Some papers tackled the issue of measuring the parameters in cats (Bourdeau et al 2004, Vidal et al 2009, Szczepanik et al 2011) and horses (Meyer andNeurand 1991, Szczepanik et al 2012).…”

“…Variations in the value of the parameters also depend on the body region, therefore the place of measurement should be taken into consideration in the interpretation of results. Changes in the values of parameters caused by these factors were examined in dogs (Meyer and Neurand 1991, Matousek et al 2002, Watson et al 2002, Young et al 2002, Hester et al 2004, Yoshihara et al 2007, Gillard et al 2009, Oh and Oh 2009, Shimada et al 2009), in cats (Bourdeau et al 2004, Szczepanik et al 2011, and horses (Szczepanik et al 2012).…”

The purpose of this study was to evaluate transepidermal water loss, skin hydration and skin pH in normal polish ponies. Twelve ponies of both sexes were examined in the study. Measurements were taken from seven different sites: the neck region, the shoulder, thorax, lumbar, inguinal, lip region and the pinna. In each of the regions transepidermal water loss (TEWL), skin hydration and skin pH were measured. For transepidermal water loss, the lowest values were observed in the pinna (10.54 g/hm 2 ), while the highest values were observed in the lip region (30.98 g/hm 2 ). In the case of skin hydration the lowest values were observed for the thorax region (1.96 CU), and the highest for the lip region (48.28 CU). For skin pH, the lowest results were obtained in the pinna (7.03), and the highest in the lumbar region (8.05).

“…The purpose of this study is to evaluate the relationship between TEWL and impaired skin in dogs. There are some studies of TEWL in canine skin, but most of them used open-chamber-type instruments [6,13]. We measured TEWL with a closed-chamber-type instrument, which is considered to be better than the open chamber type because it minimizes the effects of a relative humidity and movement of dogs [15].…”

ABSTRACT. The correlation between skin barrier function and transepidermal water loss (TEWL) was evaluated in dogs. Stratum corneum (SC) of 10 healthy dogs was removed by tape stripping (TS), which decreased the corneal layer to allow for permeation of fluorescent dye into skin. TEWL of damaged skin was measured with the closed-chamber-type TEWL analyzer, CC-01. The frequency of TS was directly related to the decrease of SC and the increased permeation of fluorescent dye, and TEWL increased with increasing impairment of skin barrier function. The results suggest that increased TEWL reflects impaired canine skin barrier function. KEY WORDS: canine skin, skin barrier function, transepidermal water loss.J. Vet. Med. Sci. 70(8): 841-843, 2008 The skin functions as an interactive wall of mammalian body, controlling egress of water and suppressing ingress of environmental and microbial agents, thereby preventing skin diseases [3]. Therefore, the maintenance of skin barrier function is critical for the treatment of skin diseases in mammals.Transepidermal water loss (TEWL) is defined as the volume of water that passes from inside to outside of the body through the epidermal layer. TEWL measurement has been used to evaluate skin barrier function in human [1,5,8], and an increase in TEWL has been reported to reflect impairment of skin barrier function [2], i.e., high TEWL suggests low skin barrier function. In addition, in human, a number of studies have suggested that high TEWL is associated in various skin diseases, including atopic dermatitis, psoriasis, contact dermatitis, and ichthyosis [4,10,11,14]. Thus, TEWL is thought to be a useful parameter that characterizes skin barrier function in human.Many skin disorders are suggested to be associated with skin barrier function in dogs [7]. However, the relationship between skin disease and the barrier function is not well analyzed because of paucity of studies on the TEWL value in normal and damaged canine skin. In this study, we evaluated whether TEWL could reflect impaired canine skin barrier function or not.Ten healthy dogs (8 crossbred dogs and 2 beagles, age range 7-13 years, 1 female, 3 sterilized females, and 4 neutered males) were enrolled in this study. All animals were fed on the same food and kept in an air-conditioned room. Two different anatomical areas, lumbar skin and inguinal skin, were used for TEWL measurement. Hair on both areas of each dog was clipped before measurement. Measurements were performed at 23-25°C and 45-65% relative humidity. All dogs were acclimated at least 30 min to the measurement conditions. All experiments were performed in accordance with the guidelines of animal research committee in Tokyo University of Agriculture and Technology.Tape stripping (TS) is a well-known method to artificially damage the stratum corneum (SC) [9,12]. TS was performed on the left and right sides of lumbar skin and inguinal skin of five of ten dogs, using adhesive cellophane tape (Nichiban, Tokyo, Japan). The tape-stripped areas were divided into five pa...
