Mast cell products, such as histamine, may contribute to the initiation and progression of the atherosclerotic plaque. To determine the relationship that may exist between early atherosclerotic plaques and mast cells we studied the aortas and coronary arteries of 115 young subjects aged 15 to 34 years who had traumatic deaths. Lesions were classified as(More)
A group of green sunfish was collected from a selenium-rich lake and compared with a similar group collected from a control lake upstream in the same drainage system in east Texas. Since the level of selenium in kidneys of these fish was relatively high (averaging 11 ppm on a fresh weight basis), histopathological and ultrastructural data were collected.(More)
Redear sunfish (Lepomis microlophus) were collected from Martin Lake in east Texas. For at least 8 months, 1 year earlier, aqueous selenium-laden effluent from man-made sources was released into this 5,000-acre reservoir (unpublished data). Redear sunfish from a reference lake, 8 km upstream, were collected for comparison to Martin Lake fish. The(More)
This report provides morphological and analytical data for a group of green sunfish collected from an area relatively free of metals and a second group of the same species collected from a lake into which selenium had been discharged. Neutron activation data of livers (and kidneys) collected from these fish show an average of about 11 ppm selenium (fresh(More)
Two cases of fatal attacks by large cats are presented. In the first case, a 30-year-old female zoo worker was attacked by a jaguar that had escaped its cage. In the second case, a 2-year-old girl was fatally injured by her father's pet leopard. The pattern of injuries in these cases is nearly identical to those of these cats' prey in the wild.
