Beneficial effects of Teucrium polium hydroalcoholic extract on letrozole-induced polycystic ovary syndrome in rat model.

Objective: Polycystic ovary syndrome (PCOS) is an endocrine disorder that disrupts the menstrual cycle and causes infertility. Considering the increasing use of medicinal plants, the present study aimed to evaluate the effects of Teucrium polium L. on letrozole-induced PCOS in female rats.

Skin biophysical assessments of four types of soaps by forearm in-use test.

Background: While soaps are the most commonly used cleansing agents for human skin, they also damage the epidermal barrier and potentially increase the risk of disorders such as contact dermatitis.

Aims: This study set out to compare the potential skin irritancy of four types of soaps and their effects on the skin barrier function and biophysical parameters.

Methods: In a nonblinded comparative study, three types of soaps (alkaline, creamy, and glycerin soaps), and a syndet were applied to four different groups of 15 healthy subjects.

Effects of four soaps on skin trans-epidermal water loss and erythema index.

Background: Various tests have been carried out to determine the irritant potential of soaps/cleansers.

Objectives: This study was carried out to compare the effects of four different soap formulations on biophysical parameters of the skin, including trans-epidermal water loss (TEWL) and erythema index.

Methods: Four different soap formulations (creamy, glycerin containing, syndet, and traditional alkaline soaps) were studied.
