Flavonoids Reduce Morphine Withdrawal In-vitro

open access: yesJournal of Pharmacy and Pharmacology, 1998
AbstractThe effects of quercetin, flavone, catechin and chrysin on the naloxone-precipitated withdrawal contracture of the acute morphine-dependent guinea-pig ileum have been investigated in-vitro.After 4 min in-vitro exposure to morphine a strong contracture of guinea-pig isolated ileum was observed after the addition of naloxone.

Blood-central nervous system barriers in morphine dependence and withdrawal. : Blood-brain barrier in morphine withdrawal stress

open access: yes, 2004
The status of the blood-CNS barriers during morphine dependence or withdrawal is still unknown. Morphine-withdrawal is associated with profound stress response, immediate early gene expression in the CNS and alterations in neurochemical metabolism. Thus,

The effect of 5-HT2A receptor stimulation on morphine withdrawal symptoms in mice [PDF]

open access: yesمجله علمی دانشگاه علوم پزشکی کردستان, 2023
Background and Aim: Serotonergic system has a role in morphine dependence and withdrawal symptoms via its receptors. On the other hand, the effect of 5-HT2A receptor on withdrawal symptoms has not been evaluated completely.

Hypothalamic orexin--a neurons are involved in the response of the brain stress system to morphine withdrawal. [PDF]

open access: yesPLoS ONE, 2012
Both the hypothalamus-pituitary-adrenal (HPA) axis and the extrahypothalamic brain stress system are key elements of the neural circuitry that regulates the negative states during abstinence from chronic drug exposure.

Activity in projection neurons from prelimbic cortex to the PVT is necessary for retrieval of morphine withdrawal memory

open access: yesCell Reports, 2021
Summary: Previous work has shown that the paraventricular nucleus of the thalamus (PVT) is an important region that is involved in the conditioned context-induced retrieval of morphine withdrawal memory.

Involvement of noradrenergic transmission in the PVN on CREB activation, TORC1 levels, and pituitary-adrenal axis activity during morphine withdrawal. [PDF]

open access: yesPLoS ONE, 2012
Experimental and clinical findings have shown that administration of adrenoceptor antagonists alleviated different aspects of drug withdrawal and dependence. The present study tested the hypothesis that changes in CREB activation and phosphorylated TORC1

Pathological regional blood flow in opiate-dependent patients during withdrawal: A HMPAO-SPECT study [PDF]

open access: yes, 1998
The aims of the present study were to investigate regional cerebral blood flow (rCBF) in heroin-dependent patients during withdrawal and to assess the relation between these changes and duration of heroin consumption and withdrawal data.

Role of corticotropin-releasing factor (CRF) receptor-1 on the catecholaminergic response to morphine withdrawal in the nucleus accumbens (NAc). [PDF]

open access: yesPLoS ONE, 2012
Stress induces the release of the peptide corticotropin-releasing factor (CRF) into the ventral tegmental area (VTA), and also increases dopamine (DA) levels in brain regions receiving dense VTA input.
