Although Nerium indicum poisoning is a globally rare occurrence, Nerium oleander poisoning is known to occur frequently in the Mediterranean regions. To our knowledge, this is the first reported case of accidental Nerium indicum poisoning in Korea. Its poisoning symptoms and signs are similar to that of digitalis poisoning, because of the presence of cardiac glycosides in Nerium indicum. A 16-year-old boy was admitted to the emergency department four hours prior to the accidental ingestion of Nerium indicum petals. The patient complained of nausea, vomiting, and dizziness. His initial vital signs were stable; laboratory blood test results were within normal levels, except for the blood digoxin level (1.5 ng/dL). An electrocardiogram (ECG) analysis showed normal sinus rhythm, progressive PR prolongation and second-degree Morbiz type I AV block. Conservative treatments including activated charcoal administration were conducted, because toxic symptoms and signs were not severe. The patient was admitted to the intensive care unit for close observation. His ECG was converted to normal rhythm after 1 day and the toxic symptoms and signs were completely resolved after 4 days.

OBJECTIVE:
To compare the clinical efficacy between Wei's triple nine needling combined with esculin and digitalis glycosides eye drops and esculin and digitalis glycosides eye drops alone for presbyopia complicated with visual fatigue of liver depression and spleen deficiency.
METHODS:
Forty-six cases (92 eyes) with presbyopia complicated with visual fatigue of liver depression and spleen deficiency were randomly divided into an observation group (23 cases) and a control group (23 cases, 2 cases dropped off). The cases in the observation group were treated with Wei's triple nine needling and esculin and digitalis glycosides eye drops. The acupoints included Shangming (Extra), Chengqi (ST 1), Cuanzhu (BL 2) to Jingming (BL 1), Sizhukong (TE 23) to Taiyang (EX-HN 5), etc; the needling was given once every other day, three times a week, and the eye drops were given one drop each time, three times a day. The cases in the control group were only treated with the eye drops. Both groups were treated for 7 days as one course of treatment, and 2 courses of treatment were given. The visual fatigue core symptoms score, adjustment amplitude, adjustment lag and best average corrected visual acuity were observed in the two groups before treatment, 1 week and 2 weeks into treatment, respectively.
RESULTS:
Compared before treatment, the visual fatigue core symptoms scores in the two groups were decreased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment amplitude was increased after 2-week treatment (P<0.05), while in the control group, the adjustment amplitude was increased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment lag was decreased after 1-week and 2-week treatment (P<0.05). After 2-week treatment, the visual fatigue core symptoms score in the observation group was lower than that in the control group, and the adjustment amplitude was higher than that in the control group (P<0.05). There were no significant differences in adjustment lag and best average corrected visual acuity between the two groups after 1-week and 2-week treatment (P>0.05).
CONCLUSION
Wei's triple nine needling combined with esculin and digitalis glycosides eye drops could improve the visual fatigue and eye regulation ability in patients with presbyopia complicated with visual fatigue of liver depression and spleen deficiency, and the effect is better than esculin and digitalis glycosides eye drops alone.

3.Purification of Opioid Receptor in the Presence of Sodium Ion.
Korean Journal of Anesthesiology 1996;30(6):635-641
BACKGROUND: Purification of opioid receptor is mandatory to improve opiate analgesic medication. Recently, it was reported that sodium ion increased the number of opioid binding sites for opioid antagonist. The importance of sodium ions lead us to design appropriate affinity chromatography and binding assay for the successful purification of mu-opioid receptor to homogeneity. METHODS: Opioid receptor was solubilized from rat brain membranes with a mixture of the detergents, CHAPS and digitonin, in the presence of protease inhibitors and 1M NaCl. The solubilized material was passed through an opioid antagonist(10cd) affinity column and a wheat germ agglutinin(WGA) column, set up in series, to obtain a partially purified receptor preparation. The partially purified receptor was further purified by repeating the affinity and lectin chromatography with smaller size column. RESULTS: Binding of opioid antagonist [H]diprenorphine to the partially purified or purified receptors was dependent upon the presence of sodium ions. The purified receptor showed diffuse band with a medium molecular mass of 62KD upon electrophoresis. The average specific binding activity of the purified receptor was 18.8+/-2.3 pmol/mcg protein. CONCLUSIONS: Opioid agonists and antagonists either do not bind or bind with low affinity to G protein-dissociated free opioid receptors in the absence of sodium ions. However, the free opioid receptors have a high affinity for antagonists but not agonists in the presence of sodium ions.

Mammalian acetyl-CoA carboxylase (ACC) is present in two isoforms, alpha and beta, both of which catalyze formation of malonyl-CoA by fixing CO2 into acetyl-CoA. ACC-alpha is highly expressed in lipogenic tissues whereas ACC-beta is a predominant form in heart and skeletal muscle tissues. Even though the tissue-specific expression pattern of two ACC isoforms suggests that each form may have a distinct function, existence of two isoforms catalyzing the identical reaction in a same cell has been a puzzling question. As a first step to answer this question and to identify the possible role of ACC isoforms in myogenic differentiation, we have investigated in the present study whether the expression and the subcellular distribution of ACC isoforms in H9c2 cardiac myocyte change so that malonyl-CoA produced by each form may modulate fatty acid oxidation. We have observed that the expression levels of both ACC forms were correlated to the extent of myogenic differentiation and that they were present not only in cytoplasm but also in other subcellular compartment. Among the various tested compounds, short-term treatment of H9c2 myotubes with insulin or okadaic acid rapidly increased the cytosolic content of both ACC isoforms up to 2 folds without affecting the total cellular ACC content. Taken together, these observations suggest that both ACC isoforms may play a pivotal role in muscle differentiation and that they may translocate between cytoplasm and other subcellular compartment to achieve its specific goal under the various physiological conditions.

OBJECTIVETo investigate the effects of single or combined administration of cedilanid and small-dose of enalaprilat on heart, liver, kidney and intestine damages at early stage of severe scald in rats.
METHODSForty healthy male Wistar rats were enrolled in the study and randomly divided into: sham, burn control, cedilanid, enalaprilat, cedilanid + enalaprilat groups, with 8 rats in each group. Rats, except that of sham group (simulated scald with 37 degrees C water) were inflicted with 30% TBSA full-thickness scald, and were injected with Ringer's lactate solution (4 mLxkg(-1)x1% TBSA(-1)) intraperitoneally 30 minutes after burn. Then rats in cedilanid group were given cedilanid injection (0.2 mg/kg) intravenously, and those in enalaprilat group were given enalaprilat (1 mg/kg), and cedilanid + enalaprilat group with cedilanid and enalapril in the same dosage. At 6 post burn hour (PBH) or sham injury, parameters of myocardiac mechanics were recorded with the Multiple Channel Physiological Signal Collecting and Processing System. The blood flow of the liver, kidney and intestine was respectively detected with the Laser Doppler Flowmetry at 6 PBH. Serum contents of cTnI, TBA, beta2-MG and DAO were determined at 6 PBH to reflect visceral damages.
RESULTSCompared with those in sham group, the parameters of myocardiac mechanics and blood flow of liver, kidney, intestine (158 +/- 32, 156 +/- 46, 119 +/- 30 PU, respectively) in burn control group were obviously decreased (P < 0.05), and the serum contents of cTnI, TBA, beta2-MG, DAO (5.0 +/- 0.3 microg/L, 82 +/- 23 micromol/L, 2.55 +/- 0.15 mg/L, 1.52 +/- 0.08 kU/L, respectively) in burn control group were obviously increased (P < 0.05). Compared with those in burn control group, the parameters of myocardiac mechanics and blood flow of liver, kidney, intestine in the cedilanid or enalaprilat groups increased markedly, and their serum contents of cTnI, TBA, beta2-MG, DAO decreased significantly (P < 0.05). Compared with those in burn control group, the parameters of myocardiac mechanics and blood flow of liver, kidney, intestine (240 +/- 49, 239 +/- 75, 194 +/- 55 PU, respectively) in cedilanid + enalaprilat group increased significantly (P < 0.05), and the serum contents of cTnI, TBA, beta2-MG, DAO (3.43 +/- 0.21 microg/L, 47 +/- 8 micromol/L, 2.01 +/- 0.16 mg/L, 1.17 +/- 0.15 kU/L, respectively) were decreased (P < 0.05).
CONCLUSIONSingle administration of cedilanid or small-dose enalaprilat can ameliorate impairment of cardiac functions, prevent damages to liver, kidney and intestine in early stage of severe scald in rats. Combined administration of cedilanid and small-dose enalaprilat seems to be more effective.

OBJECTIVETo investigate the effectiveness and safety of various agents on paroxysmal atrial fibrillation in the elderly over 75 years old.
METHODSTotally 264 in-patients (75-91 years old, 185 males and 79 females) with atrial fibrillation history of less than 7 days were enrolled in this study. A total of 611 atrial fibrillation episodes were recorded, but 130 episodes (22.3%) of atrial fibrillation were auto-converted to sinus rhythm. The rest 481 episodes of atrial fibrillation were divided into six groups based on the drug used.
RESULTSThe cardioversion ratio of atrial fibrillation were 9.5%, 46.9%, 71.7%, 55.9%, 32.7%, and 73.6% in control, cedilanid, amiodarone, propafenone, verapamil, and quinidine groups, respectively. Ventricular rate control were 5.4%, 83.6%, 84.9%, 77.9%, 78.8%, and 11.3% in those groups, respectively. The total effective rates of amiodarone and cedilanid groups were the highest. When the ventricular rate was controlled to below 90 bpm, the patients would almost complain of no discomfort. No severe side-effect was observed in each group.
CONCLUSIONAmiodarone and cedilanid may be the proper drugs for the treatment of paroxysmal atrial fibrillation in the elderly. The above antiarrhythmics in each therapeutic group were relatively safe and effective.

BACKGROUND: We evaluated the Vitros 950 (Johnson & Johnson Clinical Diagnostics, Inc., NY, USA) in the measurement of digoxin and theophylline levels and compared its results to those of the TDxFLx II (Abbott Laboratories, IL, USA) used for therapeutic drug monitoring (TDM) world-widely in order to assess the utility of the Vitros 950 as a TDM instrument. METHODS: From June 1997 to August 1997, 125 and 135 candidates for TDM were randomly chosen to measure digoxin and theophylline, respectively, using the Vitros 950 and TDxFLx II. The relationship between its results and those of TDxFLx II were determined. The within-run and between-run precisions of the Vitros 950 were determined using two controls (Vitros Performance Verifier I and II; J & J Clinical Diagnostics, Inc., NY, USA). The high-concentration control (Vitros Performance Verifier II) was diluted in Vitros 7% BSA to 5 dilutions. And linearity for quantitative analysis of digoxin and theophylline were determined. RESULTS: The coefficients of variation (CV) for the within-run of the Vitro 950 were 0.8% - 4.4%. And the CV for between-run precision of the Vitro 950 were 1.7% - 12.3%. The linearity of digoxin and theophylline were relatively good. The correlations (r) of digoxin and theophylline levels with those determined by the Abbott TDxFLx II were 0.95 and 0.93, respectively (P <0.001). CONCLUSIONS: The recently developed dry slide method of the Vitros 950 proves to good precision and linearity for quantitative analysis of digoxin and theophylline. Its results correlate well with those of the TDxFLx II. The Vitros 950 does not require an elaborate preparatory protocol for the sample, and is easy to use and maintain.So it is considered a highly feasible instrument for stat test.

We experienced a rare clinical manifestation of a digoxin induced catatonic stupor without other features of digoxin toxicity. This case suggests that the neurological manifestation of digoxin toxicity can occur without the usual side effects. Also, a serum digoxin level should be checked in any elderly patient presenting with abnormal cerebral func-tions, irrespective of whether or not the dose of digoxin has been changed.
