The present study deal with determination of Se:Hg ratio in six fish species collected from Shatt Al-Arab river during the period June 2010 to Augest 2010. Muscles most important commercial C. Carpio, B. luteus, L. abu, T. zilli, sharpeyi and ilisha have been analyzed after wet digestion a mixture concentrated acids (HClO4 / HNO3).The obtained results show that abu having highest ratio, while l...

introduction: effect of tripolar tens of vertebral column on slow and fast motoneurons (mns) activity of soleus muscle was previously investigated. in this study for better differentiation of the behavior of slow and fast mns, we exploited h-reflex recovery curve recording in two muscles of soleus and lateral gastrocnemius, respectively as the representatives of slow and fast muscles. methods: ...

purpose: oculocardiac reflex (ocr) is a frequent event during strabismus surgery. the aim of this study is to compare the preventive effect of intravenous lidocaine and hyoscine on ocr.methods: this prospective, randomized clinical trial was performed on 75 patients (5-63 years old) underwent strabismus surgery. patients divided randomly into three groups. intravenous hyoscine (0.2 mg/kg), lido...

objectives: toxoplasma gondii is a coccidian protozoon which forms tissue cyst in different organs of infected intermediate host. the present study was conducted to demonstrate the active form of parasite in different tissues of rat, which was experimentally infected with rh strain of toxoplasma gondii using bioassay method inmice. materials & methods: in the experimental assay, 75 rats an...

Results. In general, CNP and SNP exerted differential inhibitoiy effects on muscarinic-receptorinduced responses in CM and Sph isolated from the various species. Thus in bovine CM, SNP stimulated cGMP formation in a timeand concenu^ation-dependent manner and dose dependently inhibited CCh-induced IP3 production and contraction. These effects were inhibited by LY 83583, a soluble guanylyl cyclas...

Purpose: An appropriate activity of the knee agonist -antagonist muscles is important to resist against abnormal abduction-adduction moments loads around knee joint and reduce the risk of knee injuries. Exercise training has been commonly used as an intervention to improve neuromuscular activity within the synergic and/or agonist-antagonist muscles. However, maximizing the effectiveness of exer...

Purpose: In approaching full trunk flexion (75%-80% of full flexion), myoelectric activity of lumbar erector spinae muscles is reduced or silenced; this response is known as flexion-relaxation phenomenon (FRP). FRP is a shift in load sharing and spinal stabilization from active structures (erector spinae muscles) to passive ligamentous and articular structures. Static lumbar flexi...
