Oromucosal as an Alternative Method for Administration of Cannabis Products in Rodents

Oral administration via gavage in rodents can induce distress associated with restraint. We explored oromucosal/buccal administration of CBD-enriched Cannabis extract, where rats were treated for 15 days with the extract at 3 mg/kg/day. Treatments were administered orally with a micropipette, using an affectionate touch technique to handle the...

Establishment and Validation of a Rat Model of Pulmonary Arterial Hypertension Associated with Pulmonary Fibrosis

Here, the method of inducing pulmonary arterial hypertension associated with pulmonary fibrosis (PF-PH) rat model by injecting bleomycin into the airway is introduced. We also provide a step-by-step approach to validate this animal...

Synthesis of a Deuterated Standard for the Quantification of 2-Arachidonoylglycerol in Caenorhabditis elegans14:25

Synthesis of a Deuterated Standard for the Quantification of 2-Arachidonoylglycerol in Caenorhabditis elegans

This work describes a robust and straightforward method to detect and quantify the endocannabinoid 2-arachidonoylglycerol (2-AG) in C. elegans. An analytical deuterated standard us prepared and used for the quantification of 2-AG by isotopic dilution and liquid chromatography-electrospray ionization-tandem mass spectrometry...

Invasive Hemodynamic Characterization of the Portal-hypertensive Syndrome in Cirrhotic Rats09:37

Invasive Hemodynamic Characterization of the Portal-hypertensive Syndrome in Cirrhotic Rats

Here we describe a detailed protocol for invasive measurements of hemodynamic parameters including portal pressure, splanchnic blood flow, and systemic hemodynamics in order to characterize the portal hypertensive syndrome in...

The Mesenteric Lymph Duct Cannulated Rat Model: Application to the Assessment of Intestinal Lymphatic Drug Transport

Here we describe a technique to cannulate the mesenteric lymph duct in rats which enables quantification of lipid and drug transport via the lymphatic system following intestinal delivery. The technique can be adapted to assess mesenteric lymph concentrations and/or transport of fluid, immune cells, peptides, proteins and lipophilic...

Bile Duct Ligation in Mice: Induction of Inflammatory Liver Injury and Fibrosis by Obstructive Cholestasis08:56

Bile Duct Ligation in Mice: Induction of Inflammatory Liver Injury and Fibrosis by Obstructive Cholestasis

Disruption of bile flow results in severe inflammatory cholestatic liver injury with a characteristic time-dependent sequence of morphological alterations. Here we present a protocol for the surgical ligation of the common bile duct in mice that allows to induce a strong fibrotic response after 21 to 28...
