PURPOSE: To determine whether high-density lipoprotein and total cholesterol levels were risk factors for increased intraocular pressure in patients with chronic open-angle glaucoma or ocular hypertension. METHODS: We measured total cholesterol, high-density lipoprotein, and total cholesterol/high-density lipoprotein ratio in 25 patients with open-angle glaucoma or ocular hypertension who had taken no glaucoma medications for four weeks. We individually matched these patients to 25 control subjects who had no history of open-angle glaucoma or ocular hypertension, on the basis of age, race, gender, and history of vascular disease or diabetes mellitus. RESULTS: We found no statistical difference in the high-density lipoprotein (P = .702) or total cholesterol (P = .177) levels or total cholesterol/high-density lipoprotein ratio between groups (P = .178, paired t test). CONCLUSION: This study indicates that increased high-density lipoprotein and total cholesterol levels are not risk factors for increased intraocular pressure. 相似文献

Safe techniques for regional chemotherapy of the limbs by perfusion are now available. The method is effective in obtaining regionally confined high levels of toxic drugs or chemotherapeutic agents in the isolated areas. The best responses have been observed in limb melanoma with recurrent or intransit disease. Chemotherapy by perfusion as an adjunct to surgical excision reduces the local recurrence and the regional and lymph node metastases. Our survivals for adjunctive perfusion for Stage I melanomas with Level V and lesions 5 mm thick and thicker are better than usually reported. Regional chemotherapy has had an important role in reduction of major amputations for the control of limb melanoma. Multiple chemotherapeutic limb perfusions can further extent survival in patients with recurring melanoma. 相似文献

In recent times, airway clearance has become an increasingly important part of the treatment of patients with excessive bronchial secretions, especially those with cystic fibrosis. The number of airway clearance techniques available has also grown considerably, becoming increasingly more specific. This has allowed patients a greater choice of treatment techniques and has led to a subsequent rise in independence. This paper gives a brief overview of the methods of airway clearance currently being used by physiotherapists in New Zealand. To date, no one method has been shown to be more effective than another. It is imperative therefore, that those involved in respiratory care have a clear understanding of the airway clearance techniques available. This will allow us to provide out patients with the best possible treatment option. 相似文献

The application of a state language to the real-time control of a hybrid electric vehicle is explained. The state language has been developed both as a specification aid to the system designer and as a means for the programmer to produce microcomputer software. A translator program, which was developed on a VAX minicomputer, preprocesses the state language into a software module to be compiled by the standard Intel PL/M 86 compiler. 相似文献

A major feeding deterrent forCostelytra zealandica larvae was isolated from the root of the resistant pasture legumeLotus pedunculatus and was identified as 3R-(—)-vestitol. This compound was also identified in feeding deterrent-activeL. pedunculatus leaf extracts. (—)-Vestitol and a secondLotus isoflavan, sativan, have been reported to have phytoalexin activity, and the implications of this for the study and understanding of insect resistance are briefly discussed. 相似文献

Twenty-three apparently normal untrained men aged 20--55 participated in a 4-month self-regulated training programme ending in a marathon run. Fasting plasma and lipoprotein lipid concentrations, adipose tissue lipoprotein lipase activity, anthropometric data, alcohol consumption, smoking habits, weekly mileage run and performance on a bicycle ergometer were recorded before and after the training period. Training induced an increase in high density lipoprotein cholesterol (HDL-C) concentration which was not directly related to concomitant decreases in mean very low density lipoprotein cholesterol (VLDL-C) concentration or mean total skinfold thickness. The degree of the changes in VLDL lipids and HDL-C levels were related to pretraining values, and changes in HDL-C and VLDL triglycerides (VLDL-TG) were also associated. Initial total skinfold thickness correlated inversely with the change in VLDL-TG levels during training. The pretaining concentration of VLDL-C was related to the corresponding value for HDL-C after training. The magnitude of exercise-induced changes in VLDL-C and HDL-C levels are more related to pre-training levels than to changes in measured exercise parameters, indices of obesity or adipose tissue lipoprotein lipase activity. However, the level of adiposity of subjects at the beginning of the study influenced the response of VLDL-TG levels to increased physical activity. The data suggest that VLDL contributes to the increase in HDL-C levels with exercise but is not the major source of the increment. 相似文献

Pathological personality item responses have been shown to relate to the social desirability scale values of test items. It was hypothesized that both social desirability and pathological item-response frequency might vary as a function of the time permitted to answer test items. Two groups of Ss were administered the items of the Maslow, Birch, Honigman, McGrath, Plason, and Stein Security-Insecurity Inventory. Social desirability scale values for the items were established. Maximal reading time required for each item was also determined, and both groups were permitted to view each item for the same established length of time. 1 group was allowed 2 sec., the other group 10 sec. for each response. It was observed that time pressure reduced the number of pathological item responses, and that items scaled either high or low in social desirability tended to be answered in the socially desirable direction under time pressure. Females generally provided more critical or pathological item responses than did males. (24 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
