  • RETINAL TOXICITY OF INTRAVITREAL GENTAMICIN IN RABBITS I. A HISTOPATHOLOGIC STUDUY

    In order to explore retinal toxicity and to estimatequot;safe dosagequot;of intravitreal gentamicin 21 Dutch-belted rabbits divided into 5 dosage groups and 1 control group were investigated.The results showed that, in 3 000mu;g group, optic disc swelling and vein dilating were observed ophthalmoscopieally. Histopathologie study displayed the retinal necrolysis. In 50~500mu;g groups,the retinal pigment change was revealed within 3~14 days after the injection.Histopathologic study displayed that the retinal damages were confined in outer layers of retina in early stage. Inner layers of retina were also influenced in late stage. The results demontrated that with increasing intravitreal gentamiein,retinal damages are gradully aggravated,and even if intravitreal gentamicin was in minimum dose,retinal damages was still observed.

  • Evaluation on the Effect of Improved Oven for Defluorination in China

    Objectives To analyze the effect of improved oven for defluorination in coal-burning endemic fluorosis areas in China, and to provide evidence for the prevention and control of fluorosis. Methods Electronic databases including CNKI, CBM, VIP and CDMD-D (1989 to 2005), were searched. We also checked the reference lists of relevant articles. We selected relevant articles according to the predefined inclusion and exclusion criteria. The methodological quality was assessed . Data on room heat preservation and the effect of improved oven for defluorination were collected in the surveillance spots of Three Gorges Reservoir. Correlation analyses were conducted between the improved oven and its effect parameters. Results Twelve articles of low quality met the selection criteria, of which 9 were graded C and 3 were graded D in terms of the methodological quality. A negative correlation was found between the decreasing rate of normal oven use and the decreasing rate of dental fluorosis as well as of urine fluorine (Pearson correlation coefficient r = – 0.87, – 0.63, Plt;0.01, lt;0.05, respectively). Analysis also revealed a positive correlation between room heat preservation and the decreasing rate of dental fluorosis as well as of normal oven use (the two Spearman correlation coefficients and P values were the same: r = –1.00, Plt;0.01). Conclusion High-quality studies on the effect of improved oven for defluorination in China are not available. Based on the current evidence, the improved oven for defluorination and the correct use, maintenance and house rebuilding for heat preservation may help to prevent fluorosis.

  • RETINAL TOXICITY OF INTRAVITREAL GENTAMYCIN IN RABBITS Ⅱ.A HISTOCHEMICAL QUANTITATIVE ANALYSIS

    In order to explore the histochemical changes in retina after intravitreal injection of gentamycin,a histochemical quantitative analysis of cytochrome oxidase(CYO)and acetylcholinesterase(ACHE)was performed with a computerized image analysis system and was compared with that of morphological study.The results showed that CYO decreased significantly in 100mu;g dosage group.With increasing intravitreal gentamycin dosage or observed days,CYO decreased gradually in all rabbits.In 100~500mu;g dosage groups,ACHE changed mildly at 3 days of injection.It decreased significantly at 7 days.However,it was destroyed completely in 1000~3000mu;g dosage groups at 3 days.

  • Progress in the application of extracorporeal membrane oxygenation in acute poisoning

    Acute poisoning is characterized by a sudden and rapid onset, most poisons lack specific antidotes. Even with the full use of blood purification, mechanical ventilation, and various drugs, it is often difficult to change the fatal outcome of critically ill patients. In recent years, extracorporeal membrane oxygenation (ECMO) has gradually gained attention and exploratory application in the treatment of acute poisoning due to its significant cardiopulmonary function support, veno-venous ECMO is used for severe lung injury after poisoning, acute respiratory distress syndrome and respiratory failure due to ineffective mechanical ventilation, and it can also be used to assist the removal of residual poisons in the lungs. Veno-arterial ECMO is commonly employed in patients with circulatory failure following poisoning, fatal cardiac arrhythmias, and arrest of cardiac and respiratory. The application of veno-arterio-venous ECMO has also been reported. The mode of ECMO necessitates timely adjustments according to the evolving illness, while ongoing exploration of additional clinical indications is underway. This review analyzes and evaluates the application scope and effectiveness of ECMO in acute poisoning in recent years, with a view to better exploring and rationalizing the use of this technology.

  • Analysis and Countermeasures of the Potential Safety Problems of Acute Alcohol Intoxication

    ObjectiveTo explore the potential safety problems of acute alcohol intoxication. MethodsBetweenDecember 2009 and December 2012, 508 patients with acute alcohol intoxication were admitted to the Department ofEmergency of our hospital. We analyzed the potential safety problems of acute alcohol intoxication and made relative countermeasures. ResultsThe 508 cases of acute alcohol intoxication were treated with comprehensive measures, such as physical examination, health condition evaluation, airway patency maintaining, vein channel establishing, accelerating in vivo alcohol exclusion, maintaining consciousness, taking safety protective measures, and strengthening the communication between doctors and patients. There was no accident injury or death occurred. ConclusionWe should pay more attention to the potential safety problems of patients with acute alcohol intoxication, and take measures to ensure their safety.
