This multicentre, randomised, double-blind study was designed to compare the anti-emetic efficacy and safety of single oral doses of dolasetron mesilate with that of the approved oral, multiple-dose regimen of ondansetron in 399 cancer patients receiving moderately emetogenic chemotherapy. Single oral doses of 25, 50, 100 or 200 mg of dolasetron mesilate(More)
The influence of pancreatic biopsy during laparoscopy with carbon dioxide (CO2) and helium on the incidence of port site and liver metastasis in pancreatic carcinoma is still unknown. Ductal adenocarcinoma of the pancreas was induced in Syrian hamsters (n=30) by injection of N-nitrosobis-2-oxopropylamin (BOP, 10 mg/kg body weight/week) for 12 weeks. In week(More)
We report on the construction of a plasmid, pGSTag, that directs the expression in E. coli of a glutathione S-transferase fusion protein that contains a high affinity phosphorylation site by protein kinase-A (PK-A). The fusion protein, following purification from crude bacterial lysates by substrate affinity chromatography, can be labeled in vitro to high(More)
Thy-1 is a cell surface glycoprotein of unknown function that is found on nerve cells and mature T-lymphocytes. To study the regulation of Thy-1 gene expression, mouse Thy-1.2 genomic sequences were joined to various marker sequences and the resulting chimeric constructs were used to produce nearly three dozen independent lines of transgenic mice. The(More)
Exposure of mononuclear cells from the mouse peritoneal cavity to interferon (IF)-containing mouse sera enhanced phagocytosis of colloidal carbon particles by the cells. The same effect was observed when the cells were exposed to IF-containing cell culture harvest free of serum. The magnitude of this effect of IF-containing preparations paralleled the titer(More)
Es wird über eine Patientin mit subkutaner Dirofilariasis berichtet. Der Erreger konnte während der operativen Entfernung eines Oberlidtumors isoliert und bei der parasitologischen Untersuchung als Dirofilaria (Nochtiella) repens identifiziert werden. Die Kasuistik wird an Hand von Untersuchungsergebnissen erläutert, die Symptomatik der subkutanen(More)
The effect of graded doses of irradiation (cobalt-60) on the morphology of McCoy cells was analyzed, and 4,000 to 5,000 r was selected as a satisfactory dose for production of giant cells. The susceptibility of radiation-induced giant cells to chlamydial infection was compared with that of nonirradiated cells by using three strains of Chlamydia trachomatis(More)
