An experimental technique to evaluate the elastic limit for rabbit skin is developed and described. The experimental technique is designed to measure small changes in the normalized reflectivity as a function of applied stretch, with a laser wavelength of 632.8 nm and power of 1 mW. When the samples of rabbit skin are stretched, the reflectivity increases until a critical point (elastic limit) is reached. After this point, the curve drops off very quickly. The elastic limit for the male dorsal samples is less than that for the female samples, with an average strain of 14.4 and 34.6% in males and females, respectively. Moreover, our results show that the average slope of the regression lines is greater for the male dorsal samples than the dorsal female samples. This indicates that the male dorsal skin is rougher than that of the female.

Biological effects of ionizing radiation vary not merely with total dose but also with temporal dose distribution. Sparing dose protraction effects, in which dose protraction reduces effects of radiation have widely been accepted and generally assumed in radiation protection, particularly for stochastic effects (e.g.

Impaired wound healing affects the life quality of patients and causes a substantial financial burden. Hydrogen-rich medium is reported to have antioxidant and anti-inflammatory effects. However, the role of hydrogen-rich saline (HRS) in cutaneous wound healing remains largely unexplored, especially by metabolomics.

A serious challenge of the chronic administration of dexamethasone (DEX) is a delay in wound healing. Thus, this study aimed to investigate the potential of Tadalafil (TAD)-loaded proniosomal gel to accelerate the healing process of skin wounds in DEX-challenged rabbits. Skin wounds were induced in 48 rabbits of 4 groups (n = 12 per group) and skin wounds were treated by sterile saline (control), TAD-loaded proniosomal gel topically on skin wound, DEX-injected rabbits, and DEX+TAD-loaded proniosomal gel for 4 weeks.

: Sodium aescinate (SA) is commonly used topically due to its anti-inflammatory, anti-edematous, and anti-swelling properties. However, the clinical application of SA is limited by strong irritation, and cannot be used on the damaged skin and mucous membrane. This study aimed to investigate whether arginine hydrochloride (Arg·HCl) could reduce the rectal mucosal irritation of SA through the formation of a gel.

Currently, the 'gold standard' for diagnosis of Psoroptes ovis infections is detecting Psoroptes mites or eggs in skin scrapings under microscopy, but it is prone to be mis-diagnosed for detecting early infection of P. ovis. Hence, seeking a reliable diagnostic technique for detecting early-stage mite infections is extremely desirable.
