Ob.ective: Ultrasonography is a diagnostic imaging technique used to visualize sub.utaneous b.dy structures f.r identif.cation of.possib.e pathologies. In this study, we aimed to explore the clinical signif.cance of.high-f.equency ultrasound in dif.erentiating the location of.b.isters b.tween pemphigus and b.llous pemphigoid. Methods: Eighteen patients were recruited in Department of.Dermatology, Zhongda Hospital f.om 2020 to 2021 and divided into a pemphigus group (n = 8) and a b.llous pemphigoid group (n = 10) according to the diagnostic criteria f.r each. Ultrasonographic images were collected using a 50-MHz high-f.equency ultrasound system. The indexes of.ultrasonic evaluation were the layer (epidermis or dermis), size, shape, internal echo, and b.undary of.the b.ister. Categorical variab.es are expressed as n (%), and dif.erences were compared using f.sher's exact test. Results: The ultrasonographic images in the pemphigus group showed an intraepidermal semi-arc or irregular anechoic or hypoechoic areas. The inf.rior b.rders were situated ab.ve the characteristic thin linear hyperechoic b.nds of.the epidermis. A linear hypoechoic b.nd was present at the dermoepidermal junction in some cases. In the ultrasonographic images of.the b.llous pemphigoid group, the linear hyperechoic b.nds of.the epidermis were continuous and intact. An oval f.uid anechoic area (sub.pidermal b.ister) was present immediately b.low the b.nds. The location of.the b.isters in the ultrasonographic images was signif.cantly dif.erent b.tween the 2 groups (P lusion: High-f.equency ultrasound can b. used as an auxiliary means to dif.erentiate the location of.b.isters b.tween pemphigus and b.llous pemphigoid. © 2022 Hospital f.r Skin Diseases (Institute of.Dermatology), Chinese Academy of.Medical Sciences, and Chinese Medical Association, pub.ished b.

The study aimed to assess the clinical, lab.ratory, and b.ood gas analysis of.horses undergoing marcha training and the ef.ects of.voluntary ingestion of.hydroelectrolytic and energy replenishers af.er exercise. Eight horses of.b.th genders aged b.tween 5 and 10 years, were included in the study. The exercise consisted of.a 10-min warm-up f.llowed b. 45 min uninterrupted marcha on a f.at dirt track in the morning. Af.er exercise, the horses received one of.the f.llowing treatments: Drinking water (control group);Hydroelectrolytic and energy replenisher containing sodium chloride, potassium chloride, calcium acetate, magnesium chloride, sodium citrate, dextrose, maltodextrin, and sucrose in three dif.erent concentrations (Replenishers A, b. and C). The horses were distrib.ted across the f.ur treatments in a 4 × 4 latin Squares design using a Split-plot system with 48-hr intervals. Clinical and lab.ratory evaluations were conducted at f.ur time points: T0 - 5 min b.f.re exercise;T1 - up to 5 min af.er exercise;T2 - 2 hr af.er starting treatment;and T4 - 4 hr af.er b.ginning treatment. Concentrations of.urea, creatinine, lactate, phosphorus, and ionized calcium signif.cantly changed af.er exercise. An increase in b.ood pH and a decrease in chloride concentrations were ob.erved when replenishers b.and C were of.ered af.er exercise. The replacements were ingested spontaneously b. the animals in a volume greater than that of.the control group (water). Replacement b.was the most ingested b. the animals, demonstrating its greatest potential.
