Twenty-five patients presenting with severe hemorrhage from benign peptic ulcers were randomized to either endoscopic injection sclerosis using a combination of hypertonic saline- epinephrine solution and 5% ethanolamine or to hypertonic-saline epinephrine solution only. Only high risk patients with active bleeding or endoscopic stigmata of recent hemorrhage of ulcers were considered. A median duration of hospital admission and median transfusion requirements between the two types of treated groups were not significant difference. The initial hemestatic effects of HS-E solution injection group(n=l5) or combination of HS- E solution and 5% ethanolamine injection group(n=l0) were 93%, 90% respectively. The rebleeding rate of HS-E solution injection group(n =15) or combination of HS-E solution and 5% ethanolamine injection group(n=10) were 33%, 30%, respectively. So, both HS-E solution therapy group and comination of HS-E solution & 5% ethanolamine injection group were effective in initial hemostasis for bleeding peptic ulcer patients. However, for the further evaluation of therapeutic effect and comparison of rebleeding rate between the two types of therapy, we think that it will be indispensable to collect more cases and to compare with control group.

Torsade de Points is unique polymorphic ventricular tachycardia associated with QT interval prolongation. The mechanism of Torsade de Points was not defined exactly but triggered activity associated with afterdepolarization and/or dispersion of repolarization were known possible explanation. Torsade de points is most often induced by various drugs such as antiarrythmic agents, antipsychotic agents, antibiotis, and antihistamines. Astemizole(Hismanal(R)) and Terfenadine among antihistamines are reported that cause leading to a Torsade de Points. We experienced the case of Torsade de Points which was induced with Piprinhydrinate(Diphenylpyraline, Plokon(R)), antihistamine of ethanolamine derivatives, expressed recurrent syncope and dizziness in a young lady.

PURPOSE: To evaluate ethanolamine oleate (EAO)-microfibrillar collagen (MFC) mixture as a new scleroembolic material for the interventions requiring both permanent obliteration of vascular lumen and atrophy of mass, such as for the facial AVM and other hypervascular soft tissue masses. MATERIALS AND METHODS: Twenty-nine transcatheter transarterial embolizations of renal arteries were performed in six groups of rabbits classified by the EAO concentration and the addition of MFC. Postembolization angiography, gross morphological and microscopic examinations of embolized kidneys were performed immediately, 3 days, 2 weeks and 4 weeks after embotization. Analysing points were the usefulness as a scleroembolic material (endovascular retention, thrombogenic-sclerosing effect, perivascular fibrosis and inflammatory reaction), effects of the EAO concentration and the addition of MFC. RESULTS: EAO-MFC mixture satisfied all ideal conditions of scleroembolic agent;persistent endovascular retention, good thrombogenic-sclerosing effect with a mild inflammatory reaction and significant atrophy of kidney. The effect of increasing concentration of EAO was proximal embolization. The effects of MFC were promotion of proximal embolization, endovascular retention and sclerosing effect. CONCLUSION: EAO-MFC mixture can be used as a new effective scleroembolic material for the various hemodynamic situations in which embolic level can be controlled by EAO concentration and the addition of MFC.

Peripheral nerve damage in leprosy would be related to the local cell-mediated immune response to mycobacterial antigens and, presumedly, metabolic and biochemical changes of Schwann cell or circulating demyelinating factors and otherwise, autoimmune process would be involved. The neuralipid composing of cholesterol, ethanolamine glycerophosphatide, sphingomyelin, galactocerebroside(GalC), ethanolamine plasmalogen, serine and choline glycerophophatide, sulfatide are abundant in the myelin and have immunogenicity. Especially, GalC and sulfatide are known to play an important role in myelin function and its stability. The study was undertaken to detect the titers of anti-GalC and anti-sulfatide antibodies for the neural destruction mechanism of leprosy. Subjects tested were 53 leprosy patients with polar type consisting of 25 in tuberculoid leprosy(TT) and 28 in lepromatous leprosy(LL). The titeration of the antibody was done in the sera of patients and controls by enzyme-linked immunosorbent assay(ELISA). The results obtained were as follows ; 1. The detection rate of anti-GalC antibody was in 13(24.5%) of the 53 leprosy patients compared with 3(13.0%) of the 23 normal controls. Among the leprosy patients, there was 8(32.0%) in TT and 5(17.9%) in LL. 2. The detection rate of anti-sulfatide antibody was in 24(45.3%) of leprosy patients compared with 7(26.1%) of normal controls. Both types showed almost same rate of 46.4% and 44.0%, respectively. 3. Mean titer of anti-GalC antibody was 18.9+/-17.0EU/ml in leprosy patients and 12.8+/-8.8EU/ml in normal controls, with statistically insignificant level(p>0.05, one-way ANOVA). Among the leprosy patients, mean titer was 24.7+/-20.9EU/ml in TT and 13.8+/-10.5EU/ml in LL, with significance in TT(p<0.05). 4. Mean titer of anti-sulfatide antibody was 25.3+/-14.5EU/ml in leprosy patients and 18.9+/-13.8EU/ml in normal controls(p>0.05). Among the leprosy patients, mean titer was 26.0+/-15.4EU/ml in TT and 24.7+/-14.0EU/ml in LL, which was nearly same quantities in both types. 5. Examinations using Pearson correlation analysis revealed that the association between anti-GalC and anti-sulfatide antibodies was non-specific in LL(r=0.09) and TT(r=0.04). The analysis between duration of illness and anti-GalC antibody was decreasing correlation(r=-0.89, p<0.05) in LL, but slightly increasing correlation in TT(r=0.44, p>0.05). In comparison with anti-sulfatide antibody and duration, LL was higher in 41-50 years, while being higher in 31-40 years in TT, but correlation in both types could not be found(r=0.08, -0.06) In conclusion, the anti-GalC and anti-sulfatide antibodies seemed to be related with nerve damage. Hereafter we think that more study for other neural lipid should be investigated

Treatment modalities of gastric variceal bleeding are endoscopic injection sclerotherapy, endoscopic variceal ligation, combined above two method, operation, TIPS, and percutaneous transhepatic embolization. Recently, Histoacryl was introduced as a new sclerosant of acute variceal bleeding failed by others. So, we studied 18 cases of acute gastric variceal bleeding uncontrolled by EIS using Ethanolamine oleate. Intravariceal injection of Histoacryl is considered as a safe and effective method for hemostasis of intractable acute gastric variceal bleeding uncontrolled by other sclerosants. But, it is important that endoscopist should be in harmony with assistant at injection of Histoacryl. And its shooting speed should be fast because of clogging within the catheter. It is necessary to do long term study for evaluation of eradication effect in acute gastric variceal bleeding.

BACKGROUND/AIMS: Combined esophageal variceal ligation and sclerotherapy has been hypothesized to be more effective for the control of bleeding esophageal varices than ligation alone. The present study was to compare the combined therapy with ligation alone in terms of variceal eradication, rebleeding, complication and survival rates in patients with bleeding esophageal varices. METHODS: Thirty-eight patients with bleeding esophageal varices were randomly assigned to receive ligation alone in 20 patients or the combined therapy in 18 patients. The clinical and endoscopic characteristics of patients in the ligation group were similar to those of patients in the combination group. In the combination group, 1-3 mL of ethanolamine was injected proximal to each ligated site. Treatments were repeated every 2- to 3-month until varices were eradicated. RESULTS: No significant differences were found between the ligation and combination groups in variceal eradication rates (70% vs. 72%), numbers of endoscopic sessions required to achieve eradication (3.5+/-0.33 vs. 3.3+/-0.31), rebleeding rates (30% vs. 28%) or 2-yr cumulative survival rates (95% vs. 75%). There were significantly more complications in the combination group (25% vs. 89%, p=0.001). CONCLUSION: Ligation alone is recommended rather than the combined ligation and sclerotherapy because of its lower complication rates.

Ethanolamine oleate is an unsaturated fatty acid salt that has been used as a sclerosing agent because of its excellent thrombosing properties. This paper presents 1 case of intraoral multiple venous malformations treatment with 1.25% ethanolamine oleate (3.6~9.6 mg dose) intralesionally injected for 6 to 14 weeks over 2 week intervals. After the sclerotherapy, lesions almost completely disappeared without side effects. In conclusion, sclerotherapy using ethanolamine oleate is very effective against venous malformations, and sufficiently provides alternative support for surgical and other methods.]]>

OBJECTIVE: To establish a snail control approach for spraying chemicals with drones against Oncomelania hupensis in complex snail habitats in hilly regions, and to evaluate its molluscicidal effect. METHODS: The protocol for evaluating the activity of spraying chemical molluscicides with drones against O. hupensis snails was formulated based on expert consultation and literature review. In August 2022, a pretest was conducted in a hillside field environment (12 000 m²) north of Dafengji Village, Dacang Township, Weishan County, Yunnan Province, which was assigned into four groups, of no less than 3 000 m² in each group. In Group A, environmental cleaning was not conducted and 5% niclosamide ethanolamine salt granules were sprayed with drones at a dose of 40 g/m², and in Group B, environmental cleaning was performed, followed by 5% niclosamide ethanolamine salt granules sprayed with drones at a dose of 40 g/m², while in Group C, environmental cleaning was not conducted and 5% niclosamide ethanolamine salt granules were sprayed with knapsack sprayers at a dose of 40 g/m², and in Group D, environmental cleaning was performed, followed by 5% niclosamide ethanolamine salt granules sprayed with knapsack sprayers at a dose of 40 g/m². Then, each group was equally divided into six sections according to land area, with Section 1 for baseline surveys and sections 2 to 6 for snail surveys after chemical treatment. Snail surveys were conducted prior to chemical treatment and 1, 3, 5, 7 days post-treatment, and the mortality and corrected mortality of snails, density of living snails and costs of molluscicidal treatment were calculated in each group. RESULTS: The mortality and corrected mortality of snails were 69.49%, 69.09%, 53.57% and 83.48%, and 68.58%, 68.17%, 52.19% and 82.99% in groups A, B, C and D 14 days post-treatment, and the density of living snails reduced by 58.40%, 63.94%, 68.91% and 83.25% 14 days post-treatment relative to pre-treatment in four groups, respectively. The median concentrations of chemical molluscicides were 37.08, 35.42, 42.50 g/m² and 56.25 g/m² in groups A, B, C and D, and the gross costs of chemical treatment were 0.93, 1.50, 0.46 Yuan per m² and 1.03 Yuan per m² in groups A, B, C and D, respectively. CONCLUSIONS The molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones against O. hupensis snails is superior to manual chemical treatment without environmental cleaning, and chemical treatment with drones and manual chemical treatment show comparable molluscicidal effects following environmental cleaning in hilly regions. The cost of chemical treatment with drones is slightly higher than manual chemical treatment regardless of environmental cleaning. Spraying 5% niclosamide ethanolamine salt granules with drones is recommended in complex settings with difficulty in environmental cleaning to improve the molluscicidal activity and efficiency against O. hupensis snails.
