Histidine is an amino acid precursor of neuronal histamine. It is evident that peripheral injection of histidine produces effects that resemble to centrally administered histamine. The aim of the present study was to compare the effects of intracerebroventricular (ICV) injection of histamine and inraperitoneal (IP) injection of histidine on food intake in rabbits. ICV injections of histamine (1...

In this study, the effects of separate and combined intraperitoneal (IP) injections of histidine and dexamethasone were investigated on local inflammation in rats. Local inflammation was induced by subcutaneous (SC) injection of histamine (100 μl, 0.1%) in ventral surface of right hind paw. The thickness of paw was measured at 30 min before and 30, 60, 90, 120, 150 and 180 min after injection o...

objective(s) phosphatidate phosphohydrolase (pap) catalyzes the dephosphorylation of phosphatidic acid to yield pi and  diacylglycerol. two different forms of pap in rat hepatocyte have been reported. pap1 is located in cytosolic and microsomal fractions and participates in the synthesis of triacylglycerols, phosphatidylcholine, and phosphatidylethanolamine, whereas the other form of phosphatid...

The formation constants of the species formed in the systems H+ + Mo(VI) + histidine and H+ +histidine have been determined at different aqueous solutions of methanol (0 - 45 % v/v) at 25 °C andconstant ionic strength (0.1 mol dm-3 sodium perchlorate), using a combination of spectrophotometricand potentiometric techniques. The composition of the complex species was determined by thecontinuous v...

the complexation reactions between diacetyl monooxime (damo), imidazole (him), histamine (hist) and histidine (his) with co2+, ni2+ and cu2+ were studied potentiometrically in aqueous solution at 25 °c and m= 0.5 m kno3. the overall stability constants log b's of species were obtained by computer refinement of ph-volume data using best computer program. several models were tested and, based on ...

histidine at the doses 30 and 60ml /kg had no effect when injected at 7 :ooh, or at 19:00h. histidine at the doses of 120, 240 and 480 mg / kg decreased defecation at the first 8 and 24 hours post injection, respectively, when injected at 07:00h. the amino acid at the doses of 120, 240 and 480 mg / kg decreased the number of fecal pellets at 2, 8 and 24 h post injection, respectively, when inje...
