Recent studies have indicated that changes in intrarenal nitric oxide (NO) production participate in mediating arterial pressure-induced changes in urinary sodium excretion. Until recently, however, the means to measure changes in intrarenal NO activity in vivo have not been available. For the present study, changes in renal tissue NO activities were assessed directly using an NO-selective micr...

A role of nitric oxide (NO) in the regulation of sodium transporters and water channels in the salivary gland was investigated. Male Sprague-Dawley rats were treated with N(G) -nitro-L-arginine methyl ester (L-NAME, 100 mg/L drinking water) for 1 week. The control group was supplied with normal tap water. The expression of Na(+),K(+)-ATPase, type 2 Na(+)/K(+)/2Cl(-) cotransporter (NKCC2), type ...

The methods used for the quantitative determination of sugar in urine, including the polariscope, ‘give good results when the amount of sugar present is considerable, but there is always a point where the urine contains so little sugar that the results are dubious. Special met)hods have been published for the determination of sugar in normal urine. Many of these give results that are too high, ...

Copper (II) phthalocyanine and 2, 9, 16, 23 tetrakis nitro copper (II) phthalocyanine has been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalysts over nanodimensional zeolites. 4-Nitro phthalonitrile synthesized from phthaimide in three steps. The newly prepared compounds have been characterized by IR, UV-Vis,1H N...

The effects of nitric oxide (NO) and its synthase (NOS) inhibitor on the generation of spontaneous spreading depression (SD) waves in the frog retina were studied by recording spreading depression potentials (SDPs) as an index. NO-releasing reagents such as sodium nitroprusside and hydroxylamine as well as the substrate of NOS, L-arginine, increased the frequency of the occurrence of spontaneou...

We developed a direct, simple, and sensitive procedure for the simultaneous colorimetric assay of iron and copper in serum, using sodium dodecyl sulfate-ascorbic acid to dissociate iron and copper from transferrin and ceruloplasmin, respectively. We also use a new water-soluble reagent, 2-(5-nitro-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino)phenol disodium salt (nitro-PAPS) and thioglycolic ac...

The effects of nitric oxide (NO) on respiratory-related neural activity were investigated using the isolated brainstem preparation from bullfrogs (Rana catesbeiana). Addition of the NO donor, sodium nitroprusside (SNP), or the amino acid precursor for NO synthesis, L-arginine (L-Arg), produced significant increases in respiratory-related burst frequency. Inhibition of nitric oxide synthase (NOS...

We present improved correlations between theoretical and experimental determination of heat of formation of some aliphatic nitro compounds. The method is based on a previously given theoretical procedure, which is ameliorate through the introduction of suitable bond parameters. The comparison with available experimental data and previous theoretical estimation show a quite satisfactory improvem...

This study aimed to develop an environmentally friendly silver nanoparticles (AgNPs) using banana peel extract as reducing and capping agent. AgNPs obtained were characterized via Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). Preservation of blocks coated with sodium carboxymethyl cellulose (Na-CMC) Na-CMC incorporated (Na-CMC + AgNPs) for 5 days also condu...
