BACKGROUND Serial plasma carcinoembryonic antigen (CEA) levels are routinely used to detect postoperative recurrence of colon cancers. However, levels of intrinsic CEA production by individual tumors, which might be helpful for interpreting serum CEA levels, are not routinely available. MATERIALS AND METHODS CEA levels were determined in twenty tissue(More)
BACKGROUND There is a paucity of data on end-of-life decisions (EOLD) for patients in Indian intensive care units (ICUs). OBJECTIVE To document the end-of-life and full-support (FS) decisions among patients dying in an ICU, to compare the respective patient characteristics and to describe the process of decision-making. DESIGN Retrospective,(More)
1. Enzyme modulation by cadmium in selected organs of the fish, Barbus conchonius (rosy barb), was investigated in vivo (48 hr exposure to 12.6 mg/l cadmium chloride) and in vitro (10(-6) M cadmium chloride). 2. The acetylcholinesterase (AchE) activity was depressed in the gills but stimulated in the skeletal muscles and brain in vivo. The hepatic,(More)
Prolonged exposure (4 weeks) to 6.72 ppb of the organochlorine insecticide endosulfan induced disturbances in the blood and organ chemistry values of a common fish, Barbus conchonius. In blood the total lipids, cholesterol, and proteins were decreased in comparison to unexposed controls, while the free fatty acids (FFA), glucose, total phosphorus, and(More)
The rosy barb (Puntius conchonius) was exposed to copper (Cu) for short (48 hr) and long (8 weeks) terms and effects on enzyme activities and biochemical variables in the blood and tissues were examined. In vivo exposure to 571 micrograms CuSO4/liter (96-hr median tolerance limit (TLm)) for 48 hr stimulated to varying degrees acid phosphatase (AcP),(More)
Individual and combined toxicity of three pesticides, endosulfan, phosphamidon, and aldicarb was evaluated in P. conchonius. The 48 hr LC50 was 21.36 and 446.5 ppm respectively for endosulfan and phosphamidon. When tested jointly, 48 hr LC50 for different ratios of these pesticides were 0.332 (IE:3P), 0.224 (IE:1P), and 0.178 ppm (3E:1P). The cotoxicity(More)
The paper deals with a detailed histochemical mapping of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) in the diencephalon and mesencephalon of Uromastix hardwickii. In AChE in contrast to BChE preparations, most of the nuclei reveal intense activity Interestingly, the hypothalamic nuclei demonstrate positive reactions to AChE but totally(More)
