Peanut lectin (PNL) binds to a majority of mouse thymocytes (Thc) in suspension. By using cell affinity chromatography on a column of anti-PNL antibody, Thc populations at least 96 percent pure in PNL + or - cells, as judged by immunofluorescence, were obtained. PNL(+) cells are rich in Thy 1 and poor in H(2) antigens, cortisone sensitive, unresponsive to phytohemagglutinin (PHA), and immunolog...

This paper proposes a modified, genomial, version of function architecture co-design rnethod so that wider cvaluation of architecturcs from both functional arrd structural point of view can bc pcrformed. The topological rnodellirrg technique is used to creatc thc Computatiorr Irrdependent Modcl that is abscnt in thc original method. A case study has been performcd that clarif ics thc kcy idcas ...

Zusammenfassung Hintergrund Cannabis ist weltweit immer noch die am häufigsten konsumierte illegale Droge, aber auch der Einsatz von Medizinalcannabis oder als Lebens‑/Nahrungsergänzungsmittel steigt stetig. Somit sind Kenntnisse über diese verschiedenen Produkte und Komplexität rechtlichen Einordnung für Rechtsmedizin forensische Toxikologie großer Relevanz. Fragestellung Ziel Arbeit es, einen...

Oral fluid (OF) is an important matrix for monitoring drugs. Smoking cannabis is common, but vaporization and edible consumption also are popular. OF pharmacokinetics are available for controlled smoked cannabis, but few data exist for vaporized and oral routes. Frequent and occasional cannabis smokers were recruited as participants for four dosing sessions including one active (6.9% Δ9 -tetrah...

The effects of cannabis extracts on nocturnal sleep, early-morning performance, memory, and sleepiness were studied in 8 healthy volunteers (4 males, 4 females; 21 to 34 years). The study was double-blind and placebo-controlled with a 4-way crossover design. The 4 treatments were placebo, 15 mg Delta-9-tetrahydrocannabinol (THC), 5 mg THC combined with 5 mg cannabidiol (CBD), and 15 mg THC comb...

Morphine and delta9-tetrahydrocannabinol (THC) produce antinociception via mu opioid and cannabinoid CB1 receptors, respectively, located in central nervous system (CNS) regions including periaqueductal gray and spinal cord. Chronic treatment with morphine or THC produces antinociceptive tolerance and cellular adaptations that include receptor desensitization. Previous studies have shown that a...

Delta-9-tetrahydrocannabinol (Δ9-THC), the psychoactive component of marijuana, is known to suppress the immune responses to bacterial, viral and protozoan infections, but its effects on fungal infections have not been studied. Therefore, we investigated the effects of chronic Δ9-THC treatment on mouse resistance to systemic Candida albicans (C. albicans) infection. To determine the outcome of ...

The majority of MDMA (ecstasy) recreational users also consume cannabis. Despite the rewarding effects that both drugs have, they induce several opposite pharmacological responses. MDMA causes hyperthermia, oxidative stress and neuronal damage, especially at warm ambient temperature. However, THC, the main psychoactive compound of cannabis, produces hypothermic, anti-inflammatory and antioxidan...

Previous studies indicate that the CB1 cannabinoid receptor antagonist, N-(piperidin-1-yl)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-met hyl-1H-pyrazole-3-carboxamide HCl (SR141716A), inhibits the anandamide- and delta9-tetrahydrocannabinol- (THC) induced hypotension and bradycardia in anesthetized rats with a potency similar to that observed for SR141716A antagonism of THC-induced neurobehav...

The structural features of the adult rat hepatocyte (ARH) forms of cell-CAM 105, a Mr 105,000 cell adhesion molecule, were compared using a variety of immunochemical and biochemical techniques with altered forms of more basic pI present on two transplantable hepatocellular carcinomas (THC 1682c and THC AS-30D). Immunoprecipitation analysis with polyclonal (anti-gp 105-2) and monoclonal (MAb) an...
