Effectiveness of gua sha with Masanggoubang oil in rats with chronic soft tissue injury.
Adv Clin Exp Med
January 2025
Acupuncture and Tuina College, Guizhou University of Traditional Chinese Medicine, Guiyang, China.
Background: Chronic soft tissue injury is characterized by sterile inflammation and pain. Gua sha with Masanggoubang oil (GSMO) treatment has been found to possess anti-inflammatory and analgesic effects.
Objectives: To explore the mechanism of GSMO in chronic soft tissue injuries.

There is clinical concern about the combined use of alcohol and opiates. Several lines of evidence support an interaction between alcohol and the endogenous opioid system. Thus, we hypothesized that ethanol, by causing the release of opioid peptides, may sensitize the system to the action of exogenous opioids such as morphine.

We introduce two Korean-named yet transcultural feelings, and , to fill gaps in neuroscientific understanding of mammalian bondedness, loss, and aggression. is a visceral sense of connectedness to a person, place, or thing that may arise after proximity, yet does not require intimacy. The brain opioid theory of social attachment (BOTSA) supports the idea that involves increased activity of enkephalins and beta-endorphins.

Background: The opioid epidemic is leading to increased opioid use in adolescent populations. A growing body of evidence suggests that taking opioids during adolescence can disrupt normal development and impact future offspring. This study investigates the impact of paternal morphine exposure during adolescence on the hypothalamic-pituitary-adrenal (HPA) axis and release of endorphins in the offspring.

Background: Microglia, a type of resident immune cells within the central nervous system, have been implicated in ethanol-activated neuronal death of the stress regulatory proopiomelanocortin (POMC) neuron-producing β-endorphin peptides in the hypothalamus in a postnatal rat model of fetal alcohol spectrum disorders. We determined if microglial extracellular vesicles (exosomes) are involved in the ethanol-induced neuronal death of the β-endorphin neuron via secreting elevated levels of the chemokine monocyte chemoattractant protein 1 (MCP1), a key regulator of neuroinflammation.
Methods: We employed an in vitro model, consisting of primary culture of hypothalamic microglia prepared from postnatal day 2 (PND2) rat hypothalami and treated with or without 50 mM ethanol for 24 h, and an in vivo animal model in which microglia were obtained from hypothalami of PND6 rats fed daily with 2.
