The amount of polyphosphate in the intraradical and extraradical hyphae of Gigaspora margarita was estimated from successive extractions with trichloroacetic acid (TCA), EDTA, and phenol-chloroform (PC). In the intraradical hyphae, most of the polyphosphate was present in TCA- and EDTA-soluble (short-chain and long-chain) fractions, whereas most of the polyphosphate in the extraradical hyphae w...

A potent inhibitory effect of aqueous extract from N. sativa on calcium channel of guinea pig heart was found comparable and even greater than that of diltazem. The results may also indicate an opening effect for the plant on potassium channel of isolated heart.

Electrophoretic and immunoelectrophoretic studies of sera from normal, tuberculous, and noninfected tuberculin-sensitive guinea pigs. J. Bacteriol. 92:76-81. 1966.-Normal guinea pig serum was separated into seven fractions by electrophoresis on cellulose acetate membranes. Thirty antigens were found by immunoelectropho...

Metabolic syndrome is a serious health problem that is increasing worldwide particularly in aged people due to increased fructose intake in processed foods as well as physical inactivity. The present study was conducted to investigate the effect of dietary supplementation with ground seeds of Nigella sativa on the criteria of metabolic syndrome in aged rats. The present study was carried out on...

Heterologous radioimmunoassays for a semiquantitative analysis of al-microglobulin were developed, exploiting the binding between polyclonal rabbit or goat antisera against human, guinea pig, or rat almicroglobulin and ‘Z61-labeled human, guinea pig, or rat a,-microglobulin. Homologues of this protein were detected in human, guinea pig, Rhesus monkey, rat, mouse, rabbit, goat, horse, and cow se...
