Oral Supplementation of L-Carnosine Attenuates Acute-Stress-Induced Corticosterone Release and Mitigates Anxiety in CD157 Knockout Mice.

Corticosterone, an end product of the hypothalamic-pituitary-adrenal (HPA) axis, is a crucial stress hormone. A dysregulated HPA axis and corticosterone release play pivotal roles in the onset and persistence of symptoms of stress-related psychiatric disorders, such as anxiety. The intake of nutrients, probiotics, and prebiotic supplements decreases blood corticosterone levels.

[Preliminary establishment of integration of Alzheimer's disease and blood stasis syndrome tree shrew model and evaluation of intervention of Panax notoginseng saponins].

To establish the integration of Alzheimer's disease(AD) and blood stasis syndrome tree shrew model. Panax notoginseng saponins (PNS) was used to intervene the model to testify the stability of the model. The level of blood stasis of each group in the tree shrew model was evaluated by analyzing five traditional Chinese medicine(TCM) characterizations, four blood coagulation indexes, plasma nitric oxide (NO) level, plasma superoxide dismutase (SOD) level in each group.
