A 4-year-old Yorkshire terrier was presented with hindlimb paresis and urinary incontinence after accidental ingestion of an herbicide. Based on neurologic examinations, decreased hindlimb proprioception with flaccid paresis were revealed. Other possible causes of the clinical signs were excluded. The clinical signs gradually improved after administration of anti-inflammatory and antioxidant therapy. This case report is the first to describe the long-term outcome of hindlimb paresis and urinary incontinence induced by glyphosate surfactant herbicide (GPSH) poisoning in a dog.

Purpose: Although glyphosate-surfactant herbicide intoxication is relatively mild toxic in humans, we encountered an atypical clinical presentation. We performed this study to understand the atypical clinical course and factors associated with severe intoxication after glyphosate ingestion. Methods: We conducted a retrospective study of 61 patients (male 43, mean age $54{\pm}18.8$ years) who were presented with glyphosate ingestion between March 1997 and March 2011. The severe intoxication group was defined as patients with systolic blood pressure less than 90 mmHg, respiratory distress needing intubation, or altered mental state. Results: Of the 61 patients, 22 patients (36.1%) had a severe clinical course, 1 patient (1.6%) had died and 1 patient (1.6%) had moribund discharge. The most common symptoms were nausea with or without vomiting which occurred in 30 patients (49.2%). Twenty-seven patients had metabolic acidosis that was the second most common medical complication. Advanced age, pH, base excess, $HCO_3$, Sat, creatinine, X-ray abnormalities and ECG abnormalities were significant factors. Hemoglobin, platelet, $pO_2$, $pCO_2$, BUN, sodium, potassium and AST levels were not different comparing the laboratory characteristics between the severe and mild intoxication groups. Conclusion: The results of this study showed that severe intoxication occurred in 22 patients (36.1%) after glyphosate intoxication. Advanced age, pH, base excess, $HCO_3$, Sat, creatinine, X-ray abnormality and ECG abnormalities were significant predictive factors for severe intoxication in patients with glyphosate surfactant herbicide poisoning.

Glyphosate containing herbicides are an alternative to paraquat and have been widely used with increasing frequency in suicide attempts throughout Asia. It is an organophosphorus compound that is not a cholinesterase inhibitor. Daejangun powder consists of glyphosate ammonium, surfactant and another herbicide, oxyfluorfen. A 60-year-old man ingested about 300 g of Daejangun powder with 500 ml of water in a suicide attempt. He was brought to emergency room 6 hours after the ingestion and showed severe metabolic acidosis (pH 6.75), marked leukocytosis (WBC 35,800/$mm^3$), hypoglycemia (glucose 13 mg/dL) and increased liver enzymes (AST/ALT 1,683/418 IU/L). Later he developed aspiration pneumonia, acute renal failure and hyperchloremic acidosis. Upper gastrointestinal endoscopy which performed 5 days after the ingestion revealed corrosive injuries (grade 1) in both esophagus and stomach. However, intensive treatment with supportive measures improved the abnormal findings almost completely 4 weeks after the ingestion.

Organophosphates are used as herbicides. Glyphosate is one of the acidic organophosphate solution of pH4.8-6. We experienced a case of laryngeal injury after glyphosate caustic ingestion. He had a mild respiratory distress, and a laryngeal granuloma was observed in endoscopy. He received treatment with oral steroid and PPI for two weeks, the laryngeal granuloma and respiratory distress were nearly disappeared. Therefore, we expect this case report to be helpful the therapeutic formulations in the damage of larynx due to glyphosate.

경엽처리(莖葉處理) 제초제(除草劑)의 살포방법(撒布方法) 개선(改善)과 첨가제(添加劑)의 혼합처리(混合處理)에 의한 제초제(除草劑)의 살초효과(殺草效果)를 증대(增大)시킬 수 있는 방안(方案)을 모색(摸索)하고자 Glyphosate의 살포(撒布)를 수준(水準), 계면활성제(界面活性劑)의 효과(效果), Glyphosate와 황산암모늄 및 염화칼리의 첨가처리(添加處理)에 의한 Glyphosate의 살초력(殺草力) 상승효과(相乘效果)를 조사하였다. 1. 물량 40 l/10a와 80 l/10a 에 Glyphosate를 희석하여 살포(撒布)할 때는 120 l/10a 기준의 살포량(撒布量)에 비하여 살초효과(殺草效果)는 현저하게 증가(增加)되었다. 2. 계면활성제(界面活性劑)의 첨가(添加)에 따라 Glyphosate의 바랭이에 대한 살초효과(殺草效果)는 현저히 증가(增加)되었고 특히 Glyphosate 30.5g/10a에서 그 경향(傾向)이 더욱 현저하게 나타났다. 3. 황산암모늄 1, 5%를 Glyphosate 30.5g/10a와 61.0g/10a에 첨가처리(添加處理)하면 쑥에 대한 살초효과(殺草效果)는 현저히 증가(增加)되었으나 환산암모늄 10%를 첨가(添加)하면 오히려 길항적(拮抗的)으로 작용하여 살초효과(殺草效果)는 매우 불량(不良)하였으며 Glyphosate 122g/10a에서는 황산암모늄의 살초작용(殺草作用) 증진효과(增進效果)는 적었다. 4. 염화칼리 1, 2, 3%를 Glyphosate 30.5g/10a와 61.0g/10 a에 첨가처리(添加處理)하므로써 쑥에 대한 살초효과(殺草效果)는 크게 증가(增加)되었으나 Glyphosate 122g/10a에서는 염화칼리의 첨가여부(添加如否)에 관계없이 95% 이상 방제되었다. 5. 따라서 분무기(噴霧機)의 개발(開發)을 전제(前提)로 살포량(撒布量)을 80 l/10a 이하로 줄이고 계면활성제(界面活性劑)를 처리하며 황산암모늄 혹은 염화칼리를 Glyphosate에 첨가(添加)하므로써 제초제(除草劑)의 처리약량(處理藥量)을 줄이면서 제초효과(除草效果)를 증대(增大)시킬 수 있는 방법(方法)은 과수원(果樹園)이나 비농경지(非農耕地)에서 Glyphosate를 비롯한 경엽처리(莖葉處理) 제초제(除草劑)를 사용(使用)할 때 응용(應用)될 수 있을 것으로 사료(思料)된다.
