Cytogenetical and histochemical studies on curcumin in male rats

Curcumin is a major component of the curcuma species, commonly used as a yellow coloring and flavoring agent in foods. Curcumin has been demonstrated to have potent antioxidant, anti-inflammatory activity and has shown anticancer properties in many rodent models. There is the perception that since compounds are natural, they are devoid of toxicity and safe to use. Some of the active compounds i...

Cytogenetical studies in five Atlantic Anguilliformes fishes

The order Anguilliformes comprises 15 families, 141 genera and 791 fish species. Eight families had at least one karyotyped species, with a prevalence of 2n = 38 chromosomes and high fundamental numbers (FN). The only exception to this pattern is the family Muraenidae, in which the eight species analyzed presented 2n = 42 chromosomes. Despite of the large number of Anguilliformes species, karyo...

Comparative studies of 'bile salts'; preliminary survey.

5. The reaction kinetics of the hydrolytic decomposition of G2S2 and cystine in the presence of an excess of silver nitrate were studied under various conditions. The reactions were classified into three main types. 6. Acetate was shown to catalyse the reaction of cystine and, to a much lesser extent, that of. G2S2. Similarly, barbitone inhibited the cystine reaction completely, but that of G2S...

Comparative cytogenetical and morphological studies in ovarian dysgenesis.

In 14 cases of the Turner syndrome and pure gonadal dysgenesis streak gonads were studied histologically. In cases where the 46,XX line was unimpaired the blood vessels of the gonad showed severe degeneration in at least 30 to 50%. These streak gonads usually contained some of the characteristic ovarian elements as well as the vascular lesions. In gonosomal monosomy, on the other hand, a simila...
