introduction: the history of studies on blood groups dates back to early 20th century. studies have demonstrated that certain blood groups dictate tendencies toward physical or psychiatric illnesses. the present study aimed to find out the frequency of abo and rh blood groups in obsessive-compulsive disorder. methods: in this survey, descriptive study with convenient samples, male/female patien...

The purpose of this article is to report that some anti-A1 react at 37°C are IgG antibodies and clinically significant, as they can cause the destruction a proportion A1 cells in vivo following transfusion red blood cells. Therefore, when serum an individual contains anti-A1, further testing plasma against group A1, A2, O by referencing lectin (Dolichos biflorus lectin) must be performed. Confi...

Recently, total chemical synthesis of thromboxane was achieved. The in vitro activity of synthetic thromboxane A2 is indistinguishable from biologically generated material. The present study describes the in vivo characterization of synthetic thromboxane A2 on the regional blood flow distribution of the canine heart. Local injections of synthetic thromboxane A2 into the coronary vasculature cau...

Background. Experimental studies on the effects of a2-adrenoceptors on regional coronary blood flow in normal and ischemic myocardium are highly controversial. A beneficial effect on regional ischemic myocardium has been demonstrated in different animal preparations with either a2-adrenoceptor blockade or stimulation. Animal studies also demonstrated that postsynaptic a2-adrenoceptors mediate v...

although abo incompatibility between mother and fetus has long been suspected as cause of spontaneous abortion in man, its precise contribution has not been completely resolved. in spite of reports in which the incompatible mating was recognized to be a cause of habitual abortion, and which eventually results in infertility or a reduction in the number of living children compared with the numbe...

INTRODUCTION Glycoprotein IIb/IIIa (GP IIb/IIIa) is a platelet receptor composed of two subunits coded by individual genes. GP IIIa gene has two alleles: A1 and A2. The A2 allele determines higher platelet activity and was investigated many times as a potential risk factor of ACS. The influence of A1/A2 polymorphism on the prognosis in patients with ST-segment elevation myocardial infarction (S...
