This report reviews the results of prophylactic immunotherapy carried out on 105 ragweed hay fever patients treated for at least two years with an alum-precipitated pyridine ragweed (Allpyral) extracts prepared from equal parts of low and giant ragweed pollen. Good or excellent clinical results were
Selective inhibitors of the replication of the classical swine fever virus (CSFV) may have the potential to control the spread of the infection in an epidemic situation. We here report that 5-[(4-bromophenyl)methyl]-2-phenyl-5H-imidazo[4,5-c]pyridine (BPIP) is a highly potent inhibitor of the in
Hyperthermia has been shown in vitro and in vivo to potentiate the effects of ionizing irradiation. Previous studies found that hyperthermia alters the metabolism of adenosine diphosphate (ADP)-ribose polymers required for recovery from DNA damage and that poly(ADP-ribose) polymerase activity is
Pharmacological effects of the novel antipsychotic, 2-(4-ethyl-1-piperazinyl)-4-(fluorophenyl)-5,6,7,8,9,10-hexahydrocycl oocta [b]pyridine (AD-5423), were compared with those of haloperidol in rats. AD-5423 suppressed hyperactivity induced by microinjecting dopamine into the nucleus accumbens
Recently, selective and systemically active antagonists for the metabotropic glutamate 5 receptor (mGlu(5)) were discovered, and the most potent derivative was found to be MPEP (2-methyl-6-(phenylethynyl)pyridine). Given the high expression of mGlu(5) receptors in limbic forebrain regions, it was
It hs been suggested that metabotropic glutamate receptor subtype 5 (mGluR5) play a role in the expression of anxiety, based on anxiolytic-like effects of the selective mGluR5 antagonist MPEP (2-methyl-6-(phenylethynyl)pyridine) in rodent models of anxiety, including stress-induced hyperthermia
The mGlu5 receptor antagonist 2-methyl-6-(phenylethylnyl)-pyridine (MPEP) is highly anxiolytic in rodent models of anxiety. Recent studies showed that MPEP remains effective in some models of anxiety after repeated treatment, but tolerance may develop in other models. To further evaluate anxiolytic
(31)P NMR spectroscopy with surface coils has been used to monitor, in vivo, the phosphate metabolism of subcutaneously implanted mammary 16/C adenocarcinoma in C3H/He mice. This model tumor was studied during untreated tumor growth and after treatment with adriamycin, hyperthermia, and x-radiation.
Hyposensitization treatment for at least two years using pyridine-extracted alum precipitated (PEAP) extracts was carried out on 332 cases of severe hay fever, some of which were steroid dependent. Subjective self-assessment and weekly average use of additional medication were recorded, nasal
Several arenaviruses cause hemorrhagic fever (HF) disease in humans and represent important public health problems in their endemic regions. In addition, evidence indicates that the worldwide-distributed prototypic arenavirus lymphocytic choriomeningitis virus is a neglected human pathogen of
The one-pot synthesis and properties of some derivatives of 3-phenylimidazo [4,5-b]pyridine (4a-g) were described. The central action of compounds 4a, 4f and 4g has been investigated using behavioral tests in mice and rats. The tested compounds showed a potent sedative effect. Compound 4f has
Nineteen patients with hay fever symptoms received nine weekly injections of pyridine-extracted alum-precipitated grass pollen vaccine (Alavac P). The results were compared with agroup of twenty patients who received a three injection series of a glutaraldehyde-modified pollen-tyrosine vaccine
