Between June 1973 and February 1979, 409 patients with inoperable advanced non-oat cell carcinoma of the lung were randomized on RTOG protocol 73-02. Three treatment arms were evaluated: 40 Gy split course, 30 Gy continuous course, and 40 Gy continuous course. Patients were also randomized to receive cytoxan or no further therapy following irradiation.(More)
In this paper we describe two simple experimental models of diffuse interstitial renal fibrosis in the rat. One develops 25 days after unilateral renal vein ligation, and the other 15 days after unilateral ureteral double ligation and section. In both models fibrosis is examined morphologically and biochemically, the latter with emphasis on collagen(More)
OBJECTIVE To describe and compare the clinical impacts of neurocysticercosis (NC) caused by Taenia solium in humans and pigs. METHODS Comparative study of the brains of 16 asymptomatic pigs and 35 human NC cases (15 asymptomatic and 20 symptomatic). RESULTS In humans, cysticerci were more frequently located in the ventricles and subarachnoid space at(More)
This report details the patterns of tumor recurrence in two prospective randomized studies involving 551 patients with histologically proven unresectable or medically inoperable non-oat cell carcinoma of the lung treated with definitive radiotherapy. Patients were treated according to two protocols, depending on the stage of the tumor: (1) Patients with T1,(More)
Recently, the RTOG and ECOG concluded a joint randomized study on malignant gliomas that was in progress for the past five years. A total of 626 patients entered this protocol. Sixty-seven percent of the 535 evaluable patients have died and thus this represents a preliminary report of a major joint clinical trial. The objective of this study was to evaluate(More)
Entamoeba histolytica virulence has been attributed to several amoebic molecules such as adhesins, amoebapores and cysteine proteinases, but supporting evidence is either partial or indirect. In this work we compared several in vitro and in vivo features of both virulent E. histolytica (vEh) and non-virulent E. histolytica (nvEh) axenic HM-1 IMSS strains,(More)
A rabbit monospecific anti-rat uterus collagenase antibody has been used to study the distribution of collagenase in normal rat tissues by immunohistochemical methods. Indirect staining was performed with fluorescein-conjugated goat anti-rabbit immunoglobulin G antibody. The organs studied were brain, lung, myocardium, liver, spleen, kidney, adrenal,(More)
