(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Aflatoxins are one of the most potent toxic, mutagenic, teratogenic, cancerogenic, and immunosuppresive substances that naturally Occurring contaminants of food. There are some studies in various animal species that have ...
Nifedipine Enhances the Relaxant Effects of Cyclo-Oxygenase Inhibitors on the Bovine Ciliary Muscle
(MARY ANN LIEBERT, INC, 2008)
Background/Aims: The inhibition of cyclo-oxygenase (COX) enzymes and the blockade of Ca2+ channels play an important role in the regulation of smooth muscle relaxation. This study was designed to investigate the relaxant ...
Changes in spontaneous contractions of rat ileum by aflatoxin in vitro
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Aflatoxins are a group of mycotoxins produced by toxigenic strains of Aspergillus flavus, Aspergillus parasiticus and Aspergillus nomius as secondary metabolites. Most of the studies on the aflatoxins have focused mainly ...
The effect of sildenafil on the altered thoracic aorta smooth muscle responses in rat pre-eclampsia model
(ELSEVIER SCIENCE BV, 2008)
The pathophysiology of pre-eclampsia is still unknown thus effective primary prevention is not possible at the stage. The present study was conducted to research the smooth muscle responses in the pre-eclampsia model with ...
Lack of nitrate tolerance in isosorbid dinitrate- and sodium nitroprusside-induced relaxation of rabbit internal anal sphincter
(BAISHIDENG PUBL GRP CO LTD, 2008)
AIM: To investigate the tolerance development against the relaxant effect of nitric oxide donating drug isosorbide dinitrate (ISDN) and sodium nitropruside (SNP) in internal anal sphincter (IAS) smooth muscle. METHODS: ...
