CG 10213-Go, a 5-nitroimidazole derivative synthesized at the CIBA-Geigy Research Centre, Bombay, proved superior to such currently used 5-nitroimidazole derivatives as metronidazole, ornidazole, secnidazole, tinidazole and nimorazole, against experimental amoebic infections of the liver and caecum in a golden hamster model. CG 10213-Go is now undergoing(More)
Tissue inhibitor of metalloproteinase-1 (TIMP-1) was evaluated in the pre-treatment serum of 55 newly diagnosed patients with symptomatic myeloma. TIMP-1 was elevated in 47% of patients and correlated with lytic bone disease and increased bone resorption. Importantly, TIMP-1 correlated with ISS stage (p=0.005) and was an independent prognostic covariate for(More)
Chitosan is a deacetylated product of chitin produced by chitin deacetylase, an enzyme that hydrolyses acetamido groups of N-acetylglucosamine in chitin. Chitosan is a natural polymer that has great potential in biotechnology and in the biomedical and pharmaceutical industries. Commercially, it is produced from chitin via a harsh thermochemical process that(More)
Complete development of Ancylostoma ceylanicum (Hamster strain) is reported for the first time in mice. A patent infection (viz. ova in faeces) could be established only under the influence of hydrocortisone acetate. Cultures made from the faeces containing eggs produced viable larvae which were infective to mice.
In the present study the comparative in-vitro and in-vivo efficacy of Go 10213 was compared with those of metronidazole, secnidazole, tinidazole, ornidazole and nimorazole against a metronidazole-resistant strain of T. vaginalis. Go 10213 was found to be superior in activity. It appears more promising than the drugs mentioned above on the basis of the(More)
A 58-year-old white man with prostate-specific antigen (PSA) level of 6 ng/mL, a Gleason score of 6 (3+3), and T2a adenocarcinoma of the prostate underwent prostatectomy. On review of the pathology, the specimen contained a Gleason score of 8 (3+5) with other high-risk features. The patient had a persistently elevated postoperative PSA level and was placed(More)
Fourth-stage larvae and adults of Ancylostoma ceylanicum (dog strain) produced patent infections, with fertile ova, in hamsters to which they had been given in a drench. Similarly, 36-day-old (immature adult) Necator americanus given in a drench to hamsters also produced patent infections with fertile ova. The epidemiological significance of these(More)
In an experimental patent infection of Ancylostoma ceylanicum in golden hamsters the efficacy of seven anthelmintics was tested; bephenium hydroxynaphthoate, tetramisole, tetrachlorethylene, phenylene 1,4-diisothiocyanate, thiabendazole, parbendazole and mebendazole were studied. Mebendazole was the most effective, with parbendazole, phenylene(More)
