B-fluoroethylacetate에 의한 hyperkalemia 발생 예
박재홍,박성광,강성귀 대한신장학회 1985 Kidney Research and Clinical Practice Vol.4 No.2
In acidosis associated with mineral acids, acide- mia per se, results in predictable increases in serum K^+ concentration. In acidosis associated with nonmineral organic acids, serum K^+ concen- tration usually remains within the normal range in uncomplicated cases. The mechanism of this di- ffering effect of mineral and organic acidemias on transmembrane movement of K^+ remains undefined. We observed that serum K^+ was increased after ingestion of p-fluoroethylacetate 6.0gm for sucide.

These studies were conducted to investigate the effect of dietary supplemental lincomycin at different food waste supplements on performance and blood components of broiler chicks. Diets were based corn, soybean meal and contained 3,100㎉/kg ME, 21% CP for the rest two weeks. Three levels of dietary lincomycin(LM ; 0, 2.2, 4.4 mg/kg) and food waste(FW : 0, 7.5, 15%) were added for both experiments. Weight gain, feed intake and feed conversion ratio(FCR) were measured for five weeks. Blood components, liver weight and abdominal fat ratio to body weight were examined at the end of experiment. Metabolizable energy of food waste used in formulating diet prior to feeding trials were measured 2,504(Expt 1) and 2,734㎉/kg(Expt 2), respectively. In Expt 1, weight gain of birds fed 4.4mg/kg LM was significantly higher than that of no LM treatment(P〈0.05). It also tended to increase in 7.5% food waste treatment compared to that of control but was not significantly different. FCR of chicks fed 2.2mg/kg LM supplement was significantly improved compared to that of other treatments. However, chicks fed food waste supplements had higher FCR than control as a dietary FW level increased(P〈0.05). There were no significance in blood components of all treatments. Liver to body weight ratio of birds fed 7.5% FW supplements decreased significantly(P〈0.05), but was no consistency in LM treatments. In Expt 2, weight gain of chicks fed 15% FW was not significantly different from the control and 7.5% FW. It tended to increase as dietary supplemental LM increased. It also increased in no LM treatment with 15% FW compared to that of control. However, the birds fed 2.2mg/kg LM with 15% FW exhibited higher weight gain than dther treatments. As FW supplement increased, the feed intake increased significantly(P〈0.05). There were no significance in blood components except serum calcium. Weights of liver were not affected by dietary FW or LM. The results of these experiments indicated that chicks fed 4.4mg/kg LM supplements maximized growth rate of all treatments and improved FCR in 2.2mg/kg LM.

Two experiments were conducted to investigate the effect of dietary supplemental lincomycin at different food waste supplements on performance of broiler chicks. Diets were based corn, soybean meal and contained 3,078, 3,089 ㎉/kg ME, 21% CP for the first three weeks and 3,116 ㎉/kg and 19% CP for the rest two weeks. Three levels of lincomycin(LM; 0, 2.2, 4.4mg/kg) and food waste (FW;0, 5, 10%) were differently used for both experiments. Weight gain, feed intake, feed conversion ratio were weekly measured for five weeks. Blood components, liver and abdominal fat were sampled at the end of experiments. In experiment, 1 weight gain of birds fed 4.4mg/kg LM was significantly higher than that of no LM treatments (p<0.05). It was tended to decrease in 10% food waste treatment compared to that of control but was not significantly different. FCR of chocks fed LM supplement tended to improve as dietary LM level increased. It was not superior in 10% food waste treatment to that of control, but tended to improve compared to that of other treatments. Weight gain and FCR of birds fed 2.2mg/kg LM without food waste tended to improve compared to those of other treatments, but were not significantly different. Liver to body weight ratio birds fed LM supplements regardless of FW decreased significantly compared to that of control (p<0.05), but was not consistency in FW treatments. There was no significance in blood components except blood protein. In experiment 2, weight gain of chicks fed no FW showed quadratic, but increased as dietary supplemental LM increased. Birds fed 5% FW was not superior weight gain to that of other FW treatments. It also decreased in no LM treatment with 10% FW compared to that of control. However, the birds fed 4.4 mg/kg LM with 10% FW exhibited significantly higher weight gain the trend of weight gain. It tended to increase up to 10% FW combined with 4.4 mg/kg LM, but was not significantly different. Liver to body weight ratio of chicks fed LM was significantly decreased more than the control(p<0.05).The results of these experiments indicated that chicks fed 10% FW with 4.4 mg/kg LM supplements maximized growth rate of all treatments, but was not improve FCR in both experiments.

Purpose: To evaluate the long-term clinical outcomes of retinal pigment epithelium (RPE) tears after intravitreal injection of anti- vascular endothelial growth factor (VEGF) agent for the treatment of neovascular age-related macular degeneration (AMD). Methods: The authors performed a retrospective chart review of 13 eyes of 13 patients who developed RPE tears after intravitreal anti-VEGF injection between February 2009 and June 2013. We investigated continuation of the treatment after tear, visual acuity, presence of cystoid macular edema, and central macular thickness (CMT) using optical coherence tomography (OCT) before and after treatment and visual outcomes depending on foveal sparing. Results: After RPE tear, 12 of 13 patients continued injection of an anti-VEGF agent. The average number of injections was 6.08 ± 5.18. Mean visual acuity immediately after tear was 1.65 ± 0.8 log MAR, and that at the last visit was 1.82 ± 0.88 log MAR. Nine eyes with macular edema in OCT continued receiving injection, and improvement of macular edema was observed in four eyes at the final visit. The final visual acuity of patients with foveal involvement was 2.17 ± 0.49 log MAR, which was worse than the 1.51 ± 1.06 log MAR in patients without foveal involvement, although the difference was not significant (<em>p</em> = 0.295). Conclusions: When anti-VEGF injections were continued after RPE tear, no improvement in visual acuity was observed, although better anatomical outcomes did result. Patients with foveal involvement had worse visual acuity than patients without foveal involvement, but the difference was not significant. J Korean Ophthalmol Soc 2014;55(9):1340-1346
