AY 9944 [trans-1,4-bis(2-chlorobenzylaminomethyl) cyclohexane dihydrochloride] is an amphiphilic cationic molecule. This chemical is an established inhibitor of cholesterol synthesis and is teratogenic in rats. The mechanisms of this teratogenicity remain to be clarified. This study used cultured rat whole embryos to ascertain whether AY 9944 had a direct(More)
The studies reviewed indicate that brain stress system play an important role in the acquisition and maintenance of drugs of abuse that target the brain's reward centers. In doing so, they may destabilize these areas, making the perception of pleasure more elusive and difficult to attain. Withdrawal from drugs of abuse leads to the activation of brain CRF(More)
This is a report from a cooperative study on hairy cell leukemia (HCL) involving 20 Hematology Departments in Italy. Data for the patients was collected between January 1967 and December 1981 and included 235 cases of which 203 could be evaluated; 160 were males (78.8%) and 43 females (21.2%) with an M:F ratio of about 3:1; mean age was 54 years (range(More)
γ-Aminobutyric acid (GABA) inhibits insulin secretion through GABA(B) receptors in pancreatic β-cells. We investigated whether GABA(B) receptors participated in the regulation of glucose homeostasis in vivo. BALB/c mice acutely pre-injected with the GABA(B) receptor agonist baclofen (7.5mg/kg, i.p.) presented glucose intolerance and diminished insulin(More)
Bone marrow (BM) cells from 15 patients with chronic granulocytic leukemia (CGL) and 12 normal donors were placed in liquid culture for 4-7 days in the presence of fetal calf serum (FCS) or human AB serum. BM cells were plated in agar for GM-CFC growth at day 0, day 4, day 7 of culture, in the presence of human placenta conditioned medium (HPCM). The(More)
CFU-c suppressor T cells were generated in vitro by culturing overnight peripheral blood T cells from healthy donors with pokeweed mitogen (PWM), or T cells from patients with severe aplastic anemia (SAA) in remission, with culture medium (RPMI). The supernatants were removed the next morning, the cells harvested and washed, and both tested for CFU-c(More)
