Studied in the course of a multiple-modality treatment of patients with stage III to IV ovarian cancer were effects of retinol and tocopheroli acetas and enterosorption with a silicone sorbent polysorb on the processes of lipid peroxidation and indices for the antioxidant system, for which purpose 75 female subjects were examined. The results obtained showed that retinol and tocopheroli acetas and enterosorption combined in treatment of patients with stage III-IV ovarian cancer made for stabilization of the processes of lipid peroxidation as well as for normalization of blood plasma content of factors of the antioxidant defence. 相似文献

Highly comminuted supracondylar humeral fractures were stabilised in six large-breed dogs with a modified type I external fixator using a craniomedial acrylic connecting column and an intramedullary pin which was incorporated into the connecting frame. This construct provided sufficient stability to allow satisfactory bone healing in five of the six dogs, while premature removal of the intramedullary pin and external fixator resulted in subsequent refracture of the humerus in the remaining dog. Limb function at the time of final assessment was considered excellent in two dogs, good in three dogs and poor in one dog. The craniomedial acrylic connecting column simplified application of this modified type I(a) configuration to the humerus by reducing the number of clamps required; the acrylic column also facilitated contouring of the craniomedial connecting column to the brachium and was readily extended proximally to engage the intramedullary pin. In addition, the acrylic connecting column allowed placement of intramedullary pins of varying diameter. 相似文献

Actual nutrition and its association with risk factors of coronary heart disease (CHD) were studied in a population of males aged 50-54 years living in Tallinn, as a whole and with regard to their nationality. Imbalance, as well as difference in the nutrition of the Estonians and Russians have been revealed. The incidence rate of CHD is directly associated with the total fat consumption; arterial hypertension is associated with alcohol intake; excessive body weight--with low consumption of polyunsaturated fatty acids (PUSFA), low ratios of PUSFA and saturated fatty acids (SFA), and with high protein consumption. Inverse relationship of cholesterol and high-density lipoprotein (HDLP) content with fat consumption, and direct relationship with other complex carbohydrates have been recorded. Triglyceride content is directly related with the consumption of fats, proteins and complex carbohydrates, and inversely related with PUSFA consumption, cholesterol content is in inverse relationship with starch consumption. 相似文献

Errors in pointing to actual and remembered targets presented in three-dimensional (3D) space in a dark room were studied under various conditions of visual feedback. During their movements, subjects either had no vision of their arms or of the target, vision of the target but not of their arms, vision of a light-emitting diode (LED) on their moving index fingertip but not of the target, or vision of an LED on their moving index fingertip and of the target. Errors depended critically upon feedback condition. 3D errors were largest for movements to remembered targets without visual feedback, diminished with vision of the moving fingertip, and diminished further with vision of the target and vision of the finger and the target. Moreover, the different conditions differentially influenced the radial distance, azimuth, and elevation errors, indicating that subjects control motion along all three axes relatively independently. The pattern of errors suggest that the neural systems that mediate processing of actual versus remembered targets may have different capacities for integrating visual and proprioceptive information in order to program spatially directed arm movements. 相似文献
