The induction of cytotoxicity, growth inhibition, specific locus mutations, and cytological alterations such as micronuclei, chromosome/chromatid aberrations, and sister chromatid exchanged by 5-bromodeoxyuridine (BudR) in Chinese hamster ovary cells was determined. BudR shows concentration-dependent increases in cytological alterations over the range of(More)
The fluorescent properties of drumsticks, drumstick-like appendages, and other nuclear bodies in the polymorphonuclear leukocytes from six human males and females were studied with the aid of the quinacrine-mustard staining technique. Both brightly and weakly fluorescent drumsticks (in females) and drumstick-like bodies (in males) were observed, and they(More)
The induction of mutation by a variety of mutagens has been measured utilizing the hypoxanthine-guanine phosphoribosyl transferase (HGPRT) locus in Chinese hamster ovary (CHO) cells (CHO/HGPRT) system). These mutagens include physical agents such as UV light and X-rays, and chemicals such as alkylating agents, ICR-191, and metallic compounds. This system(More)
Previous studies have shown that iodinated glycerol azeo is positive in a number of in vitro mutagenicity assays including the Ames assay (TA100; TA1535), mouse lymphoma assay, Chinese hamster ovary (cytogenetic) assay and in one in vivo study, the sex-linked-recessive-lethal assay in Drosophila. Prior studies have also shown that the drug is negative in(More)
INTRODUCTION Attention-deficit/hyperactivity disorder (ADHD) appears to be associated to problems with regulation of cortical dopaminergic/noradrenergic function. The purpose of this work is to present efficacy and safety data from 10-week open label treatment with atomoxetine, a highly selective norepinephrine reuptake inhibitor, in a Spanish sample of(More)
The cytotoxicity and mutagenicity of dimethylnitrosamine (DMN) was determined in the CHO/HGPRT system. Metabolic activation of the promutagen was achieved by use of liver homogenate supernatant (S9) prepared from Aroclor 1254-induced Sprague-Dawley rats. The cytotoxic and mutagenic effects of DMN were enhanced by the inclusion of calcium chloride in the(More)
3-Chloro-p-toluidine hydrochloride (CPT-HCl) is an aniline derivative used in the manufacture of the dye palatine fast yellow; it is also registered as a selective, low-volume-use (< 45 kg/yr) avicide. Three in vitro mutagenicity tests of CPT-HCl were performed according to methods recommended by the U.S. Environmental Protection Agency (EPA): the(More)
Triamterene (2,4,7-triamino-6-phenylpteridine), a widely used diuretic/antihypertensive agent with weak antifolate activity, has been found to be positive in several in vitro assays for mutagenicity. The present studies were undertaken to characterize the potential mutagenic and antifolate activity of triamterene in the bone marrow and testes of mice with(More)
There is some discussion concerning the phenomenology of pediatric bipolar disorder. This condition is marked by irritability and sudden mood swings, and has no specific diagnostic criteria. Disagreement is even greater for bipolar disorder in preschool age. We report the case of a child of four years and nine months with diagnosis of bipolar disorder not(More)
