زمینه و هدف: اگر چه بررسی ها نشان داده اند که اندوکانابینوییدها اثراتی مرکزی بر نعوظ دارند، ولی اثر محیطی آنها بر نعوظ نامشخص می باشد. هدف از این مطالعه، بررسی اثر آنانداماید(یک کانابینویید اندوژن) بر پاسخ های شل شدگی القاء شده با تحریک اعصاب غیرآدرنرژیک غیر کولینرژیک(nanc=non adrenergic non cholinergic) در بافت کورپوس کاورنوزوم(بافت حیاتی در ایجاد نعوظ) موشهای صحرایی نر بوده است. روش بررسی: کو...
زمینه و هدف کانابینوئیدها که اجزای فعال ماری‌جوانا می‌باشند و اثراتی شبیه به اوپیوئیدها دارند. به‌علاوه میان این دو سیستم تداخلات عملکردی نیز وجود دارد. هدف این مطالعه بررسی اثر سیستم کانابینوئیدی بر اضطراب در آمیگدال مرکزی، و تداخل آن با سیستم اوپیوئیدی است. روش بررسی در مطالعه حاضر، اثر تزریق داخل صفاقی داروهای اوپیوئیدی بر پاسخ حاصل از تزریق داخل آمیگدال عوامل کانابینوئیدی در موشهای صحرایی،...
A molecular docking approach was employed to evaluate the binding affinity of six triterpenes, namely epifriedelanol, friedelin, ?-amyrin, ?-amyrin acetate, ?-amyrin and bauerenyl towards cannabinoid type 1 receptor (CB1). Molecular studies showed that epifriedelanol had strongest CB1. dynamics simulation revealed friedelin engaged in stable non-bonding interactions by a pocket close active sit...
This study aimed to explore the effect of aged pork fat on quality and volatile compounds Chi-aroma Baijiu during ageing stage. Result showed that glycerol total ester contents CBN, CB1, CB3 CB5 were significantly higher than in BL (P < 0.05), but acid did not change > 0.05). Moreover, there was a difference concentration OAVs among samples. With year increased, concentrations esters aldehydes ...
OBJECTIVE Cannabinoids are derivates of the marijuana component Δ(9) -tetrahydrocannabinol that exert their effects on mesenchymal cells and immune cells via CB1 and CB2 receptors. The aim of the present study was to evaluate the role of CB1 in systemic sclerosis. METHODS CB1-deficient (CB1(-/-) ) mice and wild-type littermates (CB1(+/+) mice) were injected with bleomycin. CB1 signaling was a...
The release of GABA from cholecystokinin-containing interneurons is modulated by type-1 cannabinoid receptors (CB1). Here we tested the hypothesis that the strength of CB1-mediated modulation of GABA release is related to the CB1 content of axon terminals. Basket cell boutons have on average 78% higher CB1 content than those of dendritic-layer-innervating (DLI) cells, a consequence of larger bo...
The CB1 cannabinoid receptor has been implicated in the regulation of bone remodeling and bone mass. A high bone mass (HBM) phenotype was reported in CB1-null mice generated on a CD1 background (CD1(CB1-/-) mice). By contrast, our preliminary studies in cb1-/- mice, backcrossed to C57BL/6J mice (C57(CB1-/-) mice), revealed low bone mass (LBM). We therefore analyzed CB1 expression in bone and co...
The effects of cannabinoid receptor agonists and antagonists on smooth muscle resting membrane potentials and on membrane potentials following electrical neuronal stimulation in a myenteric neuron/smooth muscle preparation of wild-type and cannabinoid receptor type 1 (CB1)-deficient mice were investigated in vitro. Double staining for CB1 and nitric oxide synthase (neuronal) was performed to id...
AIMS We investigated the mechanism by which cannabinoid receptors-1 (CB1) and -2 (CB2) modulate inflammatory activities of macrophages. METHODS AND RESULTS Real-time polymerase chain reaction showed the predominant CB2 expression in freshly isolated human monocytes. PMA, a potent inducer of differentiation, upregulated CB1 and increased CB1:CB2 transcript ratio from 1:17.5 to 1:3 in 5 days of...
