This study investigates the effectiveness of the antinociceptive effects of diclofenac, an NSAID, on the nociceptive behavior of morphine-treated rats on formalin test.Rats were treated with morphine-containing drinking water for twenty one days, which induced morphine dependence. The antinociceptive effects of 8, 16, and 32 mg/kg doses of diclofenac were then evaluated and compared with distil...

background : a wide range of preventive medications for migraine attacks, with varying efficacy is currently in use. studies comparing the efficacies of these drugs would be of value in the proper treatment of the disease. the present study compared the frequency, duration and intensity of migraine attacks during and following treatment with cyproheptadine (4 mg, twice daily) or blellergal (bel...

Forming limit diagrams (FLDs) are calculated based on both the Marciniak and Kuczynski (M-K)  model and the analysis proposed by Jones and Gillis (J-G). J-G analysis consisted of plastic deformation approximation by three deformation phases. These phases consisted of homogeneous deformation up to the maximum load (Phase I), deformation localization under constant load (phase II) and local necki...

The extraction behavior of Cu(II) ions from a real sulfate liquor obtained from the heap leaching stage of a copper oxide ore was investigated using a chelating reagent, Chemorex CP-150 in kerosene. A comparative study was also carried out on the extraction capability of Cu(II) ions using other solvents including D2EHPA and Cyanex 272.Chemorex CP-150 demonstrated an effective and selective extr...

BACKGROUND Phase II biotransformation reactions (also 'conjugation reactions') generally serve as a detoxifying step in drug metabolism. Phase II drug metabolising enzymes are mainly transferases. This review covers the major phase II enzymes: UDP-glucuronosyltransferases, sulfotransferases, N-acetyltransferases, glutathione S-transferases and methyltransferases (mainly thiopurine S-methyl tran...

FOREWORD The Federal Motor Carrier Safety Administration (FMCSA) Wireless Roadside Inspection (WRI) Program is demonstrating the feasibility and value of electronically assessing truck and motorcoach driver and vehicle safety at least 25 times more often than is possible using only physical roadside inspections. WRI Pilot Tests were conducted to prototype, test, and demonstrate the feasibility ...

PURPOSE Testing agents in cancers with multiple disease subtypes, in which the activity of a new treatment may vary between subtypes, presents statistical and logistical challenges. We propose a flexible phase II strategy which includes both analyses for each histology or stratum and a combined analysis which borrows information from all the patients in the study. Sequential futility analyses a...

The hepatic metabolism of benzene is thought to be a prerequisite for its bony marrow toxicity. However, the complete pattern of benzene metabolites formed in the liver and their role in bone marrow toxicity are not fully understood. Therefore, benzene metabolism was studied in isolated rodent hepatocytes. Rat hepatocytes released benzene-1,2-dihydrodiol, hydroquinone (HQ), catechol (CT), pheno...

A sensitive and selective solid phase extraction procedure for the determination of traces of Cd(II),Zn(II) and Ag(I) ions has been developed. An alumina-sodium dodecyl sulfate (SDS) coated on with2,3 Di Hydro 2,3 para tolyl Qinazoline (1 H)- 4 one (DPTQO). The influences of the analyticalparameters including pH and sample volume were investigated. Common coexisting ions did notinterfere on the...
