1. The effects of intraperitoneal injections of actinomycin D on the temporal characteristics of the accumulation of the inflammatory exudate and cells into the peritoneal and pleural cavities were studied in male Sprague Dawley rats. 2. A measurable quantity of the exudate appeared in both cavities
Bovine embryos in the early blastocyst/blastocyst stage were analysed by [5-3H]uridine labelling followed by electron microscopic autoradiography. In normal control embryos an intact zona pellucida, evenly developed blastomeres and a transparent perivitelline space were seen. In this group, the
BACKGROUND
Tumors involving the inferior vena cava and cardiac cavities are rare in nephroblastoma. When they do occur, the standard treatment is primary surgery; but this is often technically difficult.
METHODS
A 3 year-7-month-old girl was admitted because of an abdominal mass and signs of heart
Six strains of gram-negative anaerobic fusiform rods (Fusobacterium and Bacteroides spp.), isolated from deep subgingival locations in humans, were examined for (i) gliding motility in slide cultures, (iii) cell densities on nutrient agar surfaces, and (iii) sensitivity to actinomycin D. Known
Complexes of actinomycin D (AMD) and 7-amino-actinomycin D (7AAMD) with model hairpin oligonucleotide HP1 and various types of DNA in aqueous solutions were investigated by steady-state, polarized, time-resolved and stopped-flow fluorimetry, and photometry. Prompt non-stacking binding of the
The present study was designed to investigate the effect of actinomycin D, a transcription inhibitor, and cycloheximide, a translation inhibitor, on the delayed cardioprotective effect of ischemic preconditioning. Left thoracotomy was performed in anaesthetized rats at 4th/5th intercostal space and
1. To assess in vivo chemotactic activity of tumour necrosis factor (TNF), interleukin-1 (IL-1), IL-8, and cytokine-induced neutrophil chemoattractant (CINC), we injected these cytokines into the pleural cavity of rats. 2. CINC (0.1-1 microgram) and recombinant human IL-8 (rhIL-8, 0.2-5 micrograms)
The potent anticancer drug actinomycin D (ActD) acts by binding to DNA, thereby interfering with replication and transcription. ActD inhibits RNA polymerase far more specifically than DNA polymerase. Such discrimination is not easily understood by the conventional DNA binding mode of ActD. We have
The injection of platelet-activating factor (PAF) into the rat pleural cavity resulted in a marked increase in the number of eosinophils, neutrophils and mononuclear cells recovered from pleural washings after 6 hr. Within 24 hr, neutrophils and mononuclear cell counts returned to control values,
Following intraperitoneal injection of actinomycin D rats show a decrease in number of cells present in the peritoneal cavity, reaching the lowest point after 24 hr. At the same time a highly significant increase of free beta-glucoronidase and of the intracellular concentrations of both cyclic AMP
Pleuropulmonary blastoma is an uncommon paediatric neoplasm. Approximately 300 cases have been reported. In seven tumours, extension involved the left heart. Type III occurs typically at ages 3 or 4 years. We report this very unusual case of extensive disease in a 16-month old male patient. Chest
OBJECTIVE
To show a surgical video in which an incidentally found Meckel diverticulum was resected with a natural orifice-assisted laparoscopic approach during para-aortic resection of a retroperitoneal schwannoma.
METHODS
Case report (Canadian Task Force classification III).

OBJECTIVE
Term pregnancy with choriocarcinoma is a rare condition that can be a serious health threat to both the mother and the fetus. We present a rare case of term pregnancy with choriocarcinoma presenting as severe fetal anemia and postpartum hemorrhage.
METHODS
A 34-year-old woman, gravida 3
An exceedingly rare case of extragonadal immature teratoma, which occurred primarily in the uterus, is described. The tumor developed into the pelvic cavity from the uterine fundus and consisted of ectodermal, mesodermal and endodermal derivatives. There were also significant amounts of immature
BACKGROUND
To evaluate the clinical characteristics, treatment regimens, survival, and late complications in patients with nasopharyngeal carcinoma.
METHODS
Eighty-four patients diagnosed with nasopharyngeal carcinoma between 1972 and 2002 were retrospectively evaluated. Tumor status, lymph node
