In vitro shoots of thyme (Thymus vulgaris L.) were established, and the effects of the auxin indole-3-acetic (IAA) acid and the cytokinins benzyladenine (BA), zeatin (ZEA), and kinetin (KIN) at 1.0, 5.0, and 10.0 microM on rooting, biomass production, and volatile compounds production by these plants were investigated. The volatiles were extracted by solid phase microextraction (SPME) and analyzed by gas chromatography. The highest biomass shoot growth was obtained with BA at 5.0 microM, while IAA at all concentrations tested achieved 100% rooting frequency. The three major compounds were gamma-terpinene (22.8-38.8%), p-cymene (13.8-27.9%), and thymol (6.5-29.0%). Quantitative changes of these compounds were observed in response to the effect of varying growth regulators concentrations in the culture medium. Growing Thymus vulgaris L. plants in media supplemented with IAA at 1.0 microM increased volatile compounds such as thymol by 315%. Nevertheless, the same major compounds were produced in all treatments and no qualitative changes were observed in the volatile profile of thyme plants.

Objectives: Reporting the histological effects of chronic stress on certain oral tissues, as well as the capacity of Thymus vulgaris (thyme) to protect tissues from stress and link both serum cortisol and serotonin levels.
Methods: 30 rats were randomly divided into a trio of groups: normal control (no treatment), stress group (chronic stress without treatment), and treatment group (chronic stress treated with thyme at a dose of 200 mg/kg BW orally via needle gavage daily for 21 days). At the end of the experiment, tongues and major sublingual glands (SLGs) were surgically removed and processed for histological and histochemical studies.

Sperm cryopreservation provides patients undergoing oncological, surgical, or infertility treatments the opportunity to conceive their own children, using assisted reproductive technologies. However, the freezing-thawing process can negatively influence both the quantity and the quality of spermatozoa, mainly due to an excessive production of reactive oxygen species and/or an impaired antioxidant defense system in sperm. Aromatic and medicinal plants synthesize essential oils with antioxidant proprieties as a part of their ecological adaptation to environmental stress, thanks to their rich bioactive phytochemical components.

Wurmb is known to contain large amounts of polyphenols and flavonoids with antioxidative and anti-inflammatory effects. However, the biological and physiological functions of have not been scientifically investigated. Thus, we investigated the immunomodulatory effect of hot water extract (YSK-N) in mice using an immune compromised model established by forced swimming (FS).

Introduction: The liver is essential for both the body's removal of waste materials and the metabolism of nutrients, it is critical for sustaining general health. However, a number of factors, including viral infections, immune system malfunctions, cancer, alcohol intake, and drug toxicity, are contributing to the rising prevalence of liver problems. Alternative approaches to liver disease treatment are being investigated due to the potential limitations of conventional medical treatments.
