OBJECTIVE: This study aimed to investigate the incidence of cystoid macular edema and anterior uveitis associated with the use of latanoprost. DESIGN: A retrospective review of patients treated with latanoprost in the authors' practice between September 1, 1996, and August 1, 1997, was performed. PARTICIPANTS: Ninety-four patients and 163 eyes were studied. INTERVENTION: Patients presenting with signs and symptoms of ocular inflammation while receiving latanoprost were noted, and their response to the discontinuation of the drug was recorded. MAIN OUTCOME MEASURES: The presence and degree of anterior uveitis and cystoid macular edema were measured. RESULTS: Six (6.4%) of 94 patients (8 [4.9%] of 163 eyes) had anterior uveitis develop, and 2 (2.1%) of 94 patients (2 [1.2%] of 163 eyes) had cystoid macular edema develop while being treated with latanoprost. CONCLUSION: Although latanoprost is an effective ocular-hypotensive agent, the authors' experience with the drug has shown a significant incidence of anterior uveitis and cystoid macular edema. To the authors' knowledge, this is the first study to report the incidence of both cystoid macular edema and anterior uveitis associated with latanoprost therapy. Treating physicians should be aware of these potential complicating side effects of latanoprost. 相似文献

Morphological examinations were carried out on hepatocyte nuclei of streptozotocin (SZ)-induced diabetic mice. The area of hepatocyte nuclei in diabetic mice was about two times larger than that in control mice, and the incidence of hepatocytes with intranuclear inclusions was 3.4 +/- 0.2% in diabetic mice and 0% in control mice, respectively. Although the incidence of binuclear hepatocytes was not significantly different between diabetic (14.5 +/- 4.6%) and control mice (16.4 +/- 4.4%), the morphology of the nuclei of binuclear hepatocytes was apparently different between diabetic and control mice. Namely, the nuclei of binuclear hepatocytes of control mice were round and identical in ultrastructural appearance, and they did not differ from those of mononuclear diploid hepatocytes. On the other hand, the nuclei of binuclear hepatocytes of diabetic mice were not identical in distribution pattern of chromatin granules, and they frequently varied in size and showed irregular contours. 相似文献

To lower the fabrication cost of silicon solar cells, a surface treatment using a dielectric barrier discharge (DBD) instead of a wet cleaning technique was examined on electrode surfaces on silicon solar cells. The fill factor obtained through measuring current–voltage characteristics was evaluated, and the treated surface state was characterized by energy-dispersive X-ray. It was found that the DBD effectively activated the electrode surface and the surface treatment on finger electrodes contributed greatly to improve the fill factor. 相似文献

For the liquid-phase partial hydrogenation of benzene at 483 K, the selectivity toward cyclohexene was greatly improved upon treating rare earth nitride with ammonia. For YbN obtained by thermal decomposition of Yb(NH2)2 at 1173 K, the selectivity of the NH3-treated YbN was 75%, in contrast to nil for the untreated YbN. 相似文献

In real control systems, certain constraints are placed on the input, state, and output values. If such constraints are violated, the system may become unstable, in a worst‐case scenario. One of the promising approaches to solving this problem is to switch the controller according to the state of the closed‐loop system. No useful design strategy for each controller, however, has yet been developed. In addition, the determination of the controller state at the instant of controller switching has not been investigated. First, this paper presents a new design methodology which merges the switching control and H∞ controller design into one design algorithm. Second, this paper presents a way of determining the controller state at the instant of controller switching. Finally, the proposed method is applied to force control of a one‐DOF manipulator in order to demonstrate the usefulness of the proposed method. © 2002 Wiley Periodicals, Inc.

Investigations have been made on the low-temperature sinterability of calcium-doped lanthanum chromites which are to be used as interconnectors in solid oxide fuel cells (SOFCs). Nominally chromium deficient lanthanum calcium chromites (La0.7 Ca0.3 Cr1 -y O3 , y = 0.02) were found to be sinterable to 94% theoretical density at 1573 K in air, whereas no densification was observed for samples with y = 0. The two-step shrinkage process suggests a liquid phase sintering mechanism with calcium oxychromates playing an important role as the liquid phase. After sintering at 1573 K, calcium-rich substances remained at grain boundaries. 相似文献

In this study, the oxidation of ferrous iron by the acidophilic iron-oxidizing bacteria was investigated by field survey and laboratory-scale batch and continuous experiments. The activity of the acidophilic iron-oxidizing bacteria was affected by pH, water temperature and concentration of glucose. The rate of oxidation of pyrite was accelerated by the acidophilic iron-oxidizing bacteria. The number of bacteria attached to the surface of a rotating biological disk changed with the ferrous iron loading. 相似文献

An oxygen-deficient Mn(II) ferrite (Mn0.97Fe2.02O3.92) was synthesized and its reactivity to reduce CO2 gas into carbon was studied at 300°C. The oxygen-deficient Mn(II) ferrite was obtained by flowing H2 gas through Mn(II) ferrite with a nearly stoichiometric composition of Mn0.97Fe2.02O4.00 at 300° C. The lattice constant of the oxygen-deficient Mn(II) ferrite (0.8505nm) is larger than that of the Mn(II) ferrite with a nearly stoichiometric composition (0.8498nm). The chemical composition of the Mn(II) ferrite changed from Mn0.97Fe2.02O4.00 to Mn0.97Fe2.02O3.92 during the H2 reduction process, indicating that the oxygen is deficient in the spinel structure of the Mn(II) ferrite. This was confirmed by Mössbauer spectroscopy and X-ray diffractometry. The efficiency of CO2 decomposition into carbon at 300°C with the oxygen-deficient Mn(II) ferrite was much lower by about 105 than that of oxygen-deficient magnetite. This is considered to be due to the difference in electron conductivity between Mn(II) ferrite and magnetite, which determines the reductivity for CO2 into carbon by donation of an electron at the adsorption site. 相似文献
