An enzyme L-lysine-A-oxidase has been obtained from Trichoderma harzianum Rifai F-180. The analysis of serum from CBA mice immunized five times with native L-lysine-A-oxidase intravenously, at a dose of 35 U/kg, showed that the preparation had virtually no effect on the immune response to Tdependent antigen. L-lysine-A-oxidase at a dose of 35 U/kg administered twice intradermally has no effect ...

BACKGROUND Accidental intravenous introduction of commercial bovine thrombin (BT) during use of fibrin glue may result in profound hypotension. Commercial human thrombin (HT) is now available. This study compared the effects of intravenous BT versus HT in swine. METHODS Swine received 30 U/kg BT, 60 U/kg BT, 30 U/kg HT, or 60 U/kg HT intravenously. Mean arterial pressure (MAP) and survival we...

in order to investigate the effects of mycorrhiza symbiosis and different nitrogen levels on yield, yield components and essential oil content and yield of fennel (foeniculum vulgare mill.) and ajowan (carum copticum l.), a field experiment was arranged in a factoriel based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of...

We investigated the growth and nutrient uptake of the Lycopersicon esculentum symbiosis mycorrhiza-defective plant mutant rmc, challenged with arbuscular mycorrhiza (AM) fungal propagules, in the presence or absence of roots of the commercial wild-type tomato cv. Golden Queen (GQ). Two plants shared the middle (combi) compartment of a horizontal three-compartment split-root pot with one part of...

We examined whether the reduced mycorrhization of abscisic acid (ABA)-deficient tomato mutants correlates with their incapacity in ABA biosynthesis and whether this effect is dependent on ethylene production. The mycorrhization of notabilis and sitiens mutants, which have different ABA deficiencies and an excess of ethylene production, was analyzed. Comparative analysis of the ABA-deficient tom...

Mycorrhizal spores were found to be closely associated with bacteria on their spore wall surface known as mycorrhiza associated bacteria (MAB) and its play a major role in the plant growth promotion by production of many known and unknown metabolites, nutrient solubilization and suppression of many soil borne pathogens in rhizosphere of crop plants. The present study was carried out to understa...

The release of histaminase activity in plasma after small intravenous of heparin was studied in 85 normal subjects and patients. In normal subjects, plasma histaminase activity (basal level, 1.7+/-0.1 U/ml, mean +/-SEM) increased 1.6+/-0.2 U/ml after 10 U of heparin/kg, 8.5+/-2.4 U/ml after 20 U/kg, and 33+/-4.9 U/ml after 75 U/kg. The extent of the increase varied widely among individuals but ...

to evaluate the effects of biological phosphorous, chemical fertilizers and limited irrigation regime on quantitative and qualitative characteristics of two different grain sorghum cultivars (kimiya and speedeh), this experiment was conducted in research farm of college of agriculture, university of tehran during 2009 growing season. the experimental treatments were arranged as split split plot...

Although hypoglycemic doses of insulin (0.24-7.5 U/kg s.c.) did not significantly change acetic acid-induced writhing in mice, they dose-dependently attenuated formalin-induced nociceptive responses, and their effects were more potent on the second phase (ID50 = .62 U/kg) than on the first (ID50 > 7.5 U/kg). Intracerebroventricular doses of insulin (250-1000 microU/animal) mimicked the effects ...
