Radiosurgery using a stereotactic headframe system for irradiation of brain tumors in dogs.     

N V Lester  A L Hopkins  F J Bova  W A Friedman  J M Buatti  S L Meeks  C L Chrisman 《Journal of the American Veterinary Medical Association》2001,219(11):1562-7, 1550

Radiation therapy of brain tumors in dogs typically involves administration of multiple fractions over several weeks. Fractionation is used to minimize damage to normal tissue. Radiosurgery uses multiple non-coplanar stereotactically focused beams of radiation in a series of arcs to deliver a single dose to the target with extreme accuracy. The large number of beams facilitates a high degree of conformation between the treatment area and the target tumor and allows for a steep dose gradient; the use of nonintersecting arcs minimizes exposure of normal tissue. Computed tomography with a stereotactic localizer secured to the skull allows generation of a 3-dimensional image of the target and provides accurate spatial coordinates for computerized treatment planning and delivery. Three dogs were treated with radiosurgery, using 1,000 to 1,500 cGy. A linear accelerator mounted on a rotating gantry was used to generate and deliver the radiation. Two dogs with meningiomas survived 227 and 56 weeks after radiosurgery. A dog with an oligodendroglioma survived 66 weeks. No complications were observed following the use of this technique.  相似文献   

Tomato glycoalkaloids: role in the plant and in the diet     

Friedman M 《Journal of agricultural and food chemistry》2002,50(21):5751-5780

Tomatoes, a major food source for humans, accumulate a variety of secondary metabolites including phenolic compounds, phytoalexins, protease inhibitors, and glycoalkaloids. These metabolites protect against adverse effects of hosts of predators including fungi, bacteria, viruses, and insects. Because glycoalkaloids are reported to be involved in host-plant resistance, on the one hand, and to have a variety of pharmacological and nutritional properties in animals and humans, on the other, a need exists to develop a better understanding of the role of these compounds both in the plant and in the diet. To contribute to this effort, this integrated review presents data on the history, composition, and nutrition of tomatoes, with special focus on the assessment of the chemistry, analysis, composition, nutrition, microbiology, and pharmacology of the tomato glycoalkaloids comprising alpha-tomatine and dehydrotomatine; their content in different parts of the tomato plant, in processed tomato products, and in wild and transgenic tomatoes; their biosynthesis, inheritance, metabolism, and catabolism; plant-microbe relationships with fungi, bacteria, viruses, insects, and worms; interactions with ergosterol and cholesterol; disruption of cell membranes; tomatine-induced tomatinases, pantothenate synthetase, steroid hydroxylases, and cytokines; and inhibition of acetylcholinesterase. Also covered are tomato-human pathogen relationships and tomatine-induced lowering of plasma cholesterol and triglycerides and enhancement of the immune system. Further research needs in each of these areas are suggested. The overlapping aspects are discussed in terms of general concepts for a better understanding of the impact of tomato glycoalkaloids in the plant in general and in food in particular. Such an understanding can lead to the creation of improved tomatoes and to improved practices on the farm and in the consumption of tomatoes.  相似文献   

X-ray diffraction studies on the crystallinity and molecular weight of humic acids     

S.A. VisserH. Mendel 《Soil biology & biochemistry》1971

Humic acids of different origins were investigated for crystallinity by means of X-ray diffraction techniques. Only the humic acid formed in a culture of Aspergillus flavus on a modified Czapek-Dox medium which contained 0·1 % phthalate was crystalline as found by electron microscopy and confirmed by X-ray diffraction techniques.  相似文献

Vibriolytic antibody-forming cells: a new application of the Pfeiffer phenomenon   总被引：2，自引：0，他引：2

Complement-mediated immune lysis was first described by Pfeiffer after observing an immune reaction against Vibrio cholerae. Application of this reaction in agar gel, with viable vibro organisms, gave results which were unique compared to the red blood cell or enterobacterial systems. Among these was the lack of a detectable "background," a lengthened latent period and differentiable results among the three major cell wall antigens characteristic of this bacterial groups.  相似文献
