Histochemical study on thiamine.
The authors have applied the thiochrome method for determining thiamine to histochemical investigations and could observe the localization of thiamine in cells and tissues (1-6). Independently of our study, v. Muralt (7) had already reported a investigation on histological pictures of thiamine in peri pheral nerves by the thiochrome method, which was however unavailable to the authors at that t...
متن کاملHistochemical study on orotic acid.
Recently orotic acid has been noticed as a growth factor and regarded as a pre cursor of nucleic acid (1, 2). But its distribution in organisms has scarcely been studied except for tracing the acid using C14-labeled compound (3). The authors have found that orotic acid shows a whitish blue primary fluorescence, which is re markably intensified by adding H2O2. Applying this property to histochem...
متن کاملLocalization and Study of Histochemical Effects
A high capacity for accumulation of Mn was reported for sunflower plants. Localization of excess Mn is therefore of special interest for understanding metal tolerance mechanisms in this species. In this study, structural and histochemical alterations caused by Mn accumulation in leaves were investigated in sunflower (Helianthus annuus L. cv. Azar-ghol) plants grown in nutrient solution. In the ...
متن کاملStudies on Thiamine Analocues
Several analogues of thiamine’ are known to compete with the vitamin when administered to animals. Thus, Woolley and White (1) have observed that pyrithiamine caused the manifestation of typical thiamine deficiency symptoms, which could be competitively overcome by the vitamin. The antivitamin effect of oxythiamine in mice has been reported by Soodak and Cerecedo (2). Cerecedo et al. (3, 4), co...
متن کاملA Histochemical and Cytochemical Study
Localization of 5’-nucleotidase in the frog retina was investigated using histochemical and cytochemical techniques. Light-microscopic observations revealed the presence of this enzyme in the inner retinal layers (the nerve fiber layer, ganglion cell layer, and inner plexiform layer). Ultrastructural investigations revealed that the enzyme activity is associated with the plasma membranes of the...
