Circulating immune complexes (IC) in the sera of patients with oral cancer have been measured by using polyethylene glycol (PEG) precipitation assay. At least 60% of patients with carcinomatous buccal mucosa were found to have markedly higher amounts of IC. Results have been discussed in view of other types of cancer and the various methods used for the(More)
BACKGROUND The management of complicated parapneumonic effusions (CPE) and empyema by chest tube drainage usually fails because of thick viscous fluid and multiple pleural space loculations. The use of intrapleural fibrinolytic agents facilitates pleural drainage and can obviate the need for more invasive surgical interventions in these types of effusions.(More)
The sensitivities of normal and preneoplastic rat hepatocytes have been tested against four organotin hydroxamates in vitro. These organotin hydroxamates are soluble in lipids but not in aqueous medium. The solubility in lipid had initially been utilized in the pilot experiments with Ehrlich ascites tumor cells containing lipids in the ascites fluid.(More)
A mammary tumor-associated antigen (MTAA) of the murine mammary tumor virus (MuMTV)-induced spontaneous mammary tumors of C3H/J mice was purified and partially characterized. The crude extract of the mammary tumor, when subjected to DEAE-cellulose chromatography and eluted with a discontinuous NaCl gradient, provided three major protein peaks, of which only(More)
Alteration of surface receptor of Ehrlich tumour cells by concanavalin A (Con A), shortwave UV and UV plus Con A have been studied. DNA of nuclear chromatins is highly sensitive to UV but receptor glycoprotein sites are UV resistant as evidenced by their retention of agglutination properties after radiation. Con A and UV plus Con A treatments of tumour(More)
Main objective of this study is to compare and assimilate the digital elevation models (DEMs) generated using C-band Envisat, L-band ALOS PALSAR Interferometric SAR (InSAR) datasets and Cartosat-1 optical stereo data. The study area is Dehradun city and surroundings including lower Shivalik hills i.e. the younger Himalayas in the south and higher Himalayas(More)
Out of 56 thioacetamide (TAA)-fed rats hepatocellular carcinoma were found in four instances after 300, 360, 450 and 495 days in the present experiment. Of the four tumours, two showed lung metastasis. The size of TAA-treated hepatocyte nucleoli increased greatly after several weeks of feeding. Two enzymes, succinate dehydrogenase and glucose-6-phosphatase(More)
An identical component of tumor associated antigen (TAA) was detected in all clinical stages of the carcinoma of cervix (CaCx), in both premenopausal and postmenopausal patients, using heterologous antisera against the cancer tissues by immunodiffusion and immunoelectrophoretic tests. The TAA appeared to be cross-reacting specifically with carcinoma of(More)
