Ayurvedic Emphasis in Duchenne Muscular Dystrophy: A Case Study

Duchenne muscular dystrophy is one of the most common dystrophinopathies known. It is the most common hereditary neuromuscular disorder and is inherited in an X-linked recessive manner. Incidence is 1:3500 live male infants, characterised by progressive weakness of a selective group of muscles without involvement of nervous system. Age of onset being 3-10 years, many children unable to walk before 18 months of age. The patient usually dies by 18-20 years of age. 80% carries have high CPK values with female being the one. Dystrophin gene is the largest human gene with 79 exons, codes for protein dystrophin required for stabilisation of protein complex at sarcolemma, the abnormal DMD gene is on X chromosome at Xp21 locus. Dystrophin deficiency thus, leads to destruction of muscle fibres and progressive muscular weakness. Corticosteroids are the only medications that have shown to alter the course of DMD but have side effects like weight gain, decreased appetite, increase changes of cataract and osteoporosis. The present study is about management 8 years old male child with B/L lower limb weakness and calf muscle hypertrophy.etc, so according to Ayurvedic management with Panchkarma procedures and internal medicines given the case was managed. Successful improvement in CPK values along with the signs and symptoms was observed. As per Ayurvedic Siddhant and Samprapti application considering Adibalapravrittavyadhi and the Beejabhaga avayava dushti the management done. There is no treatment in any system of medicine and prognosis being unpreventable, Ayurveda instills a regenerative mechanism in neuromuscular disorders with special concern of Panchkarma, Rasayanas, Rasa aushadhi, etc. By this the deterioration can effectively be prolonged and quality of life improved.

A study to correlate serum pseudocholinesterase and serum creatine phosphokinase levels in acute organophosphorus poisoning with respect to Peradeniyaorganophosphorus poisoning scale

Background: Organophosphorus insecticides are one of the most common causes of poisoning in India. It has a high mortality rate and accounts for a third of suicidal deaths in south-east Asia.Methods: The objectives were to estimate serum pseudocholinesterase and creatine phosphokinase (CPK) levels in organophosphorus poisoning and correlate them with theseverity and prognosis described by the Peradeniya organophosphorus poisoning (POP) scale at initial presentation.This was a cross-sectional study conducted over 18 months. A total of 180 organophosphorus-poisoning subjects were divided into mild, moderate and severe grades based on POP scale at admission. Serum pseudocholinesterase and CPK levels were estimated at admission. The outcome was noted, and the results were statistically analysed.Results:It was found that 112 (62.2%), 51 (28.3%) and 17 (9.4%) patients had mild, moderate and severe poisoning, respectively, according to POP scale. Mean pseudocholinesterase level (units/litre) was 2393.29, 1104.37 and 638.18 and mean serum CPK level (units/litre) was 153.41,344.94 and 280.53 in mild, moderate and severe poisoning, respectively. ICU and ventilator were required for 84 (46.75%) and 72 (40%) patients, respectively. Mortality was 17.8%. Negative, weak and significant correlation was seen between POP score and pseudocholinesterase (r=-0.265, p=0.00). Positive, moderate and significant correlation was seen between POP score and CPK levels (r=0.449, p=0.00).Conclusions: POP scale applied at admission along with serum pseudocholinesterase and CPK levels serve as a simple and effective system to determine early need for ventilation and mortality in rural, peripheral centres in developing nations.

Assessment of serum cardiac troponin-I over serum CPK-MB in early diagnosis of acute myocardial infarction (AMI)

Background: The early mortality rate from AMI is 30% with about half of them occurring within 1hour of disability. Although the mortality rate after admission for AMI has declined by 30% over the past decades, approximately 1 of every 25 patients who survive the initial hospitalization die in the first year after AMI. The gold standard for diagnosis of MI has been an elevated serum level of creatinine kinase – myocardial band (CK- MB), the cardiac-specific isoenzyme of CK. However, elevated CK-MB may not detect all myocardial necrosis. In patients who die suddenly after severe or silent episodes of ischemia, autopsies frequently reveal micronecrosis that was not reflected in routine CK-MB measurements. The present study was undertaken to know that serum Cardiac Troponin-I is more sensitive marker than serum CPK-MB in early diagnosis of acute myocardial infarction (AMI).Methods: The study was carried out in tertiary care hospital in Gulbarga. The study was undertaken with an aim to study that serum cardiac troponin-I (cTnl) is more sensitive than serum CK-MB in early diagnosis of acute myocardial infarction (AMI). The study was conducted on patients admitted with history of chest pain suggestive of AMI as diagnosed by WHO criteria to medicine ward of Basaveshwar Teaching and General Hospital, Gulbarga. The period of study was from June 2012 to June 2014. The sample size included 100 patients with history of chest pain suggestive of AMI, selected by simple random method.Results: Our results revealed that cardiac troponin I was more sensitive (62%) than CK-MB in overall cases admitted in between 6-24 hrs from the onset of chest pain. Maximum number (41%) of AMI patients were affected on the anterior wall followed by Inferior wall of AMI. 11 percent were affected with Antero lateral wall wereas 5 to 6 percent were affected with anteroseptal and global acute and right ventricular AMI was seen among 2 percent of patients. Anterior wall AMI was the significantly affected site with AMI (ʎ2:12.5, P:0.0004). The maximum number of acute myocardial infarctions were ST elevation myocardial infarctions. 28% of cases where CKMB is normal, the cTnI detects the AMI cases indicating its sensitivity.Conclusions: Cardiac troponin-I (cTnI) was more sensitive serum marker than CKMB in the early diagnosis of acute myocardial infarction (AMI). Anterior wall was the most significantly affected site of AMI. In the future, further improvements in analytical performance may open additional diagnostic windows

A prospective pharmacovigilance study to evaluate adverse effect profile of first line anti-tubercular drugs in newly diagnosed sputum positive patients

Background: Tuberculosis (TB) continues to remain one of the most pressing health problems in India with highest TB burden country in the world. Anti-tubercular therapy (ATT) induced organ toxicities are potentially serious ADRs of first line ATT regimen. The underlying mechanism of ATT-induced ADRs especially hepatotoxicity and the factors predisposing to its incidence which is significantly high in Indians are not clearly understood. It's vital to emphasize on ATT induced ADRs as it has direct influence on therapeutic outcome; result in high dropout rate and potential to develop MDR/XDR cases. ADR monitoring help us to revise the treatment protocol thereby improve treatment adherence and therapeutic outcome. Objective of this study is therefore designed to explore and monitor ADRs of first line anti-TB drugs.Methods: In this prospective observational study 60 TB patients (18-70 yrs) of either sex, newly sputum positive with normal parameters were included. Patients were followed up for six months aiming primarily to assess rate of ADRs and to identify preventable and potentially serious ADRs of anti-TB drugs. The ADRs of ATT on various organ systems (heart, kidney and liver), biochemical and haematological parameters were assessed and compared after 2 and 6 months; gender and age specific adverse events were also studied. Data obtained was analysed using student’s t-test of OpenEpi statistical software.Results: Study clearly revealed that ATT exhibit significant increase in toxicity markers viz. liver enzymes (p<0.01), urea and creatinine (p<0.01), ESR (p<0.05) and PTINR (p<0.01), wherein decrease in Hb% (p<0.01) when compared to baseline.Conclusions: ATT related ADRs is the major cause of dropouts and development of MDR/XDR cases. It's crucial to develop strategies to ameliorate ADRs both to improve the quality of patient care and to control TB safely. The data obtained from present study may be helpful in developing these effective strategies.

A Single Intraperitoneal Injection of Endotoxin Changes Glial Cells in Rats as Revealed by Positron Emission Tomography Using ¹¹CPK11195 / 대한핵의학회잡지

PURPOSE: Intracranial administration of lipopolysaccharide (LPS) is known to elicit a rapid innate immune response, activate glial cells in the brain, and induce depression-like behavior. However, no study has focused on the changes in glial cells induced by intraperitoneal injection of LPS in vivo.METHODS: Ten adult male Fischer F344 rats underwent [¹¹C]PK11195 PET before and 2 days after intraperitoneal injection of LPS to evaluate the changes in glial cells. The difference in standardized uptake values (SUV) of [¹¹C]PK11195 between before and after injection was determined.RESULTS: There was a cluster of brain regions that showed significant reductions in SUV. This cluster included the bilateral striata and bilateral frontal regions, especially the somatosensory areas.CONCLUSIONS: Changes in activity of glial cells induced by the intraperitoneal injection of LPS were detected in vivo by [¹¹C]PK11195 PET. Intraperitoneal injection of LPS is known to induce depression, and further studies with [¹¹C]PK11195 PET would clarify the relationships between neuroinflammation and depression.

Cold Medications Aggravated Rhabdomyolysis Symptoms Induced by Building Construction Work and Strenuous Exercise: a Case Report

SUMMARY: A 21-year-old healthy Korean man worked on a building construction site every day for almost 2 months and exercised every day for 1 or 2 hours after working hard. He felt dizziness, nausea, and experienced vomiting and body aches immediately after exercise and immediately took cold medicines including acetaminophen, cimetidine, bepotastine, and Codenal? complex for the common cold symptoms for 2 days because he was scheduled to participate in navy training at that time. He complained of severe trapezius pain and aches in his left calf 3 days after joining the Navy training. Testing revealed creatine phosphokinase (CPK) 6260 U/L, myogloblin 176 mcg/L in the urine, liver enzymes increased, and oliguria, suggesting rhabdomyolysis. He recovered with intravenous fluids without any complications.

Serum dosage of CPK-MB in dogs with ST deviation by chemiluminescence / A dosagem sérica de CPK-MB em cães com desvio ST por quimiluminescência

Although frequently in humans, hypoxic and ischemic heart diseases are poorly documented in dogs, with only few reports of acute myocardial infarction (AMI) in this species. Some electrocardiographic findings might suggest myocardium hypoxia/ischemia, like ST segment elevation or depression, but there are no studies showing whether deviations in ST segment are associated to myocardial injury and serum increase of creatine phosphokinase (CPK-MB). In order to investigate possible myocardial cells injury in poor perfusion conditions, 38 dogs were studied, 20 with normal electrocardiogram and 18 with ST segment elevation or depression, recorded in lead II, at a paper speed of 50 mm/sec and N sensibility (1mV=1cm). Serum measurement of creatine phosphokinase isoenzyme MB (CPK-MB) in normal dogs (group 1) determined control values (in ng/mL), which were compared to those obtained from dogs with deviation (group 2), which allowed confirmation or not of myocardial injury. CPK-MB mean values obtained from dogs in groups 1 and 2 were 0.540ng/ml (SD±0.890)ng/mL and 0.440ng/mL (SD±1.106), respectively. At a significance level of 5%, the relation of CPK-MB with age, mass and total creatine phosphokinase (CPK-T) was not significant in groups 1 and 2. CPK-MB showed no difference, at 5% level, between groups 1 and 2. In conclusion, it is possible to use the human chemiluminescent immunometric assay kit in canine species and that hypoxia/ischemia revealed by ST segment deviation does not mean significant myocardium injury.(AU)

Embora frequente em humanos, as doenças hipóxicas e isquêmicas do coração são pouco relatadas em cães, com poucos relatos de infarto agudo do miocárdio (IAM) nesta espécie. Alguns achados no eletrocardiograma podem sugerir hipóxia/isquemia miocárdica, como a elevação ou depressão do segmento ST, mas não há estudos que mostram se os desvios do segmento ST estão associados a lesões miocárdicas e aumento sérico da creatinafosfoquinase (CPK-MB). A fim de investigar possíveis lesões nas células miocárdicas em condições de má perfusão, 38 cães foram estudados, 20 com eletrocardiograma normal e 18 com elevação ou depressão do segmento ST, registrados em papel, na derivação II, velocidade de 50 mm/s e sensibilidade N (1mV = 1cm). A mensuração da creatinafosfoquinase isoenzima MB (CPK-MB) em cães normais (grupo 1) determinou os valores controle (em ng/ml), que foram comparados com os obtidos a partir de cães com desvio (grupo 2), permitindo a confirmação ou não da lesão miocárdica. Os valores médios de CPK-MB obtidos de cães nos grupos 1 e 2 foram 0,540ng/ml (DP±0,890) e 0,440ng / ml (DP ± 1.106), respectivamente. A um nível de significância de 5%, a relação de CPK-MB com a idade, massa e creatinofosfoquinase total (CPK-T) não foi significativa nos grupos 1 e 2. Não houve diferenças na CPK-MB, ao nível de 5%, entre os grupos 1 e 2. Conclui-se que é possível utilizar o kit de ensaio imunométrico por quimioluminescência humano na espécie canina e que a hipoxia/isquemia revelada pelos desvios do segmento ST, não significa lesão miocárdica.(AU)

Impacto económico del precondicionamiento isquémico remoto en la revascularización miocárdica / Economic impact of remote ischemic preconditioning on myocardial revascularization

Introducción: condicionar el corazón para mejorar sus capacidades cardioprotectoras endógenas con el uso de isquemias breves a distancia proporciona un novedoso abordaje potencial a la protección miocárdica durante la cirugía cardiaca. Objetivo: identificar el impacto económico del precondicionamiento isquémico a distancia en los pacientes revascularizados quirúrgicamente. Métodos: se realizó un estudio longitudinal prospectivo experimental en dos grupos de 100 personas, a los que se les realizó revascularización por injerto de la arteria coronaria. Se procedió a colocar un torniquete en el brazo no dominante en quienes se incluyeron en el grupo de estudio prueba, alternando tres insuflaciones con tres desinsuflaciones con una presión de 200 mmHg, manteniéndola por espacio de cinco minutos cada una, este proceder se realizó previo, durante y después del evento isquémico mayor que se corresponde con el pinzamiento de la arteria coronaria. Resultados: se logró una importante disminución del consumo de drogas inotrópicas, vasoactivas y de otros medicamentos ahorrándose una importante suma disminuyendo los costos hospitalarios. Comprobándose además, la disminución en la incidencia de arritmias ventriculares letales, bajo gasto cardiaco fatal y de muerte postoperatoria, en todos los casos muy por debajo de la predicción previamente realizada para estas complicaciones. Conclusiones: el precondicionamiento isquémico a distancia puede ser una importante herramienta a tener en cuenta en la protección antisquémica de la revascularización miocárdica que puede disminuir la morbimortalidad y los costos hospitalarios.

Background: to condition the heart to improve its endogenous cardioprotective capacity using brief remote ischemia provides a novel potential approach to myocardial protection during cardiac surgery. Objective: to identify the economic impact of remote ischemic preconditioning in surgically revascularized patients. Methods: an experimental prospective longitudinal study was conducted in two groups of 100 people who underwent revascularization by coronary artery graft. A tourniquet was placed on the non-dominant arm in those who were included in the test study group, alternating three insufflations with three desinsufflations with a pressure of 200 mmHg, each one being maintained for five minutes. This procedure was performed prior to, during and after the greater ischemic event that corresponds to the pinching of the coronary artery. Results: an important decrease of the consumption of inotropic, vasoactive and other drugs was achieved, saving an important sum, decreasing hospital costs, and also proving a reduction in the incidence of lethal ventricular arrhythmias, low cardiac output and postoperative death which were, in all cases, below the prediction previously made for these complications. Conclusions: remote ischemic preconditioning can be an important tool to be considered in the antischemic protection of myocardial revascularization that can diminish morbimortality and hospital costs.

Prevalencia de alteraciones de la creatina-fosfoquinasa (CPK) sérica en pacientes que toman estatinas / Prevalence of abnormalities of creatine phosphokinase (CPK) levels in patients taking statins

El uso de estatinas para combatir la dislipidemia se asocia con un espectro de síntomas musculares que van desde mialgias con o sin aumento de la creatina-fosfoquinasa (CPK), hasta rabdomiólisis fatal. Objetivo: determinar la prevalencia de la elevación de la CPK en pacientes que toman estatinas y determinar los posibles factores de riesgo asociados al aumento de la CPK en estos pacientes. Métodos: estudio observacional de corte transversal en el que se evaluaron las alteraciones de la CPK en una población de 503 pacientes con tratamiento con estatinas para el control de la dislipidemia, y que asisten al Laboratorio Clínico Hematológico en Medellín, Colombia por razones diferentes a la medición de la CPK. Mediante un cuestionario aplicado a los pacientes se obtuvieron los datos demográficos, los antecedentes personales y el tipo de estatina utilizada. Resultados: 56 (11,1 por ciento) pacientes presentaron aumento de la CPK por encima del rango de referencia normal; 7 pacientes (1,4 por ciento) tenían un aumento dos veces por encima del valor superior normal, y de ellos 3 (0,6 por ciento) tenían un aumento tres veces por encima del valor superior normal. Se encontró asociación significativa entre niveles altos de la CPK con el sexo masculino y con el uso de inhibidores selectivos de la recaptación de serotonina (ISRS). No se encontró asociación con otros factores de riesgo previamente descritos en otros estudios como son el ejercicio, el consumo de alcohol, el hipotiroidismo y la dosis de estatinas, entre otros. En cuanto a síntomas musculares, el 28,4 por ciento relató dolor muscular con el uso de estatinas, 26 por ciento cansancio y 15,9 por ciento debilidad muscular. Conclusión: los hallazgos de este estudio demuestran que el aumento asintomático de la CPK en pacientes que toman estatinas para la reducción por ciento del colesterol, es mayor al previamente reportado y confirma que el sexo masculino y el uso de fármacos tipo ISRS se relacionan con un aumento de la CPK. También se encontró que el porcentaje de pacientes con síntomas musculares, especialmente dolor y cansancio, es mucho mayor a lo reportado en la literatura mundial. Desde el punto de vista clínico se desconocen las repercusiones que pueda tener el aumento asintomático de la CPK, lo que requeriría estudios de seguimiento a largo plazo.

Teicoplanin-induced Elevation of Plasma Creatine Phosphokinase in the Patient with Wound Infection: A case report

The use of teicoplanin is increasing with increase in the incidence of wound infections caused by methicillin-resistant Staphylococcus aureus. Teicoplanin has longer half-life than vancomycin, so it can be administerd once daily, whereas vancomycin has to be administered 3~4 times daily. Teicoplanin is known to have lesser side effect profiles than vancomycin, such as skin eruptions, ototoxicity and nephrotoxicity. A 27-year old women in vegetative state had a grade 3 pressure sore at coccyx area. We prescribe teicoplanin to manage wound infected by methicillin-resistant Staphylococcus aureus. Plasma creatine phosphokinase (CPK) was elevated abruptly at 9th day of teicoplanin therapy. Five days after discontinuation of teicoplanin, CPK was normalized. We experienced a case of elevation of plasma creatine phosphokinase associated with teicoplanin.

Infección aguda por VIH-1: manifestaciones inusuales de laboratorio / Acute infection by HIV-1: unusual laboratory events

El síndrome retroviral agudo presenta características clínicas inespecíficas y variables. Su ocurrencia ha sido estimada en el 40 a 90% de los sujetos que se exponen ao VIH. Comunicamos el caso de un paciente que presentó alteraciones poco comunes en el laboratorio. Incremento de LDH, CPK, pocos sintomáticas, y de enzimas hepáticas en más de diez veces su valor normal. De éstas últimas, la GPT sérica, persistió alterada por 6 meses. El hemocitológico se presentó con leucopenia y linfomonocitosis persistentes. Estas enzimas y sobretodo las isoenzimas de la CPK y LDH, podríam solicitarse como manera de monitorizar el progreso y/o resolución de este síndrome. Debido a que se incrementan quando comieza la destrucción celular, llegan a un máximo ao cabo de un tiempo y luego vuelven a la normalidad.

HiperCKemia asintomática benigna. A propósito de dos casos / Benign asymptomatic hyperCKemia. With regard to two cases

La hiperCKemia asintomática es definida como una elevación persistente de niveles séricos de Creatin Fosfoquinasa (CPK), sin manifestaciones clínicas, electromiográficas o histológicas. Su curso es benigno a largo plazo y en muchos casos no es necesario un seguimiento continuo. Si la hiperCKemia es un hallazgo incidental en unos exámenes de laboratorio de rutina, no se justifican estudios extensivos más aun si los pacientes no presentan alteraciones al exámen físico y si los estudios electromiográficos son normales. En este artículo, presentamos dos casos con hiperCKemia asintomática, que son los primeros informados en Hispanoamérica.

Asymptomatic hyperCKemia is defined as a persistent elevation of serum CPK levels, without clinical manifestation abnormal electrodiagnostic, or histologic findings. It has a long-term benign course and in many cases it is not necessary a continuous follow-up. If hyperCKemia is an incidental finding during a routine laboratory check-up, extensive studies are not justified still more if the patients do not present alterations in the physical exam and if the electrodiagnostic studies are normal. In this paper we present two cases of asymptomatic hyperCKemia, that are the first reported in Hispano-America.

Dissimilar Deletion In DMD Gene Of Two Brothers : A Case Study.

Two brothers who are affected by DMD were studied with respect to CPK assay, muscle biopsy and deletion analysis of their DNA. The severity of phenotype in these two brothers is comparable. Onset of the disease in both the cases was at 4 years of age. CPK values obtained at the age of 10 years for the elder brother and 6years for the younger one were 2550 IU and 1650 IU respectively. Muscle biopsy of the patients indicated dystrophy. PCR analysis of the patient's DNA was carried out for deletion detection in DMD gene. The deletion pattern observed for these two cases was found to be quite different from each other. In case of the elder brother, deletion was found to be expanding exons 8-13 whereas, for the younger brother exons 8-13 as well as exons 43-45 were found to be deleted.

Relationship between the Serum CPK and the Shoulder Muscle Disorder in VDT Workers / 대한산업의학회지

VDT workers are often exposed to static load in the shoulder stabilizing muscle due to repetitive work over long periods. Many investigations were reported the relationships between static load due to repetitive work and regional muscle disorder. However, diagnostic approach to work-related muscle disorder is difficult due to the absence of objective diagnostic tools. This study was performed to investigate the relationship between the serum CPK (creatine phosphokinase) concentrations and the shoulder muscle disorders. Results are as follow. 1. Mean serum CPK in total VDT workers was 67.6+/-28.4 IU/l and workers with abnormal serum CPK were 35 (21.5%). 2. Comparison between cases and controls did not show significant difference in the serum CPK level and the distribution of abnormal findings. 3. Sensitivity and specificity of the CPK test was 23.0% and 82.0%, respectively. Above results, in accordance with literatures, show that while serum CPK measure menu can be useful for the diagnosis of acute muscle injury, it does not adequately reflect the muscle disorders developed by the repetitive work of low tension over long time, such as VDT works.

Detrimental Effect of the Peritoneal Injection of Papaverine for the Occlusive Mesenteric Ischemia in Rats

This study assessed the effect of vasodilator papaverine for the occlusive mesenteric ischemia in rats. Papaverine has been used for the treatment of nonocclusive mesenteric ischemia(NOMI), but its peripheral administration for the occlusive mesentric ischemia is known hazardous. This experiment was performed to confirm the detrimental effect of the peripheral administration of papaverine for the occlusive mesenteric ischemia in rats. The experimental animals were assigned to one of three groups. In the control group, laparotomy and thoracotomy were performed and blood samples were obtained from right atria of the rats. In one experimental group, after laparotomy and SMA ligation, papaverine was injected into the parietal peritoneum and the abdomens were closed. In the other experimental group, after laparotomy and SMA ligation, abdominal closures were performed. It is known that mesenteric infarction causes elevation of total serum creatine phosphokinase(CPK) and each of its three isoenzymes and it is also known that CPK BB isoenzyme is the earliest isoenzyme of the three. In this experiment, although there were no statistical significances, total CPK and all its three isoenzymes showed higher levels after 1hour in SMA ligation with papaverine treated group than those in SMA ligation alone group. And especially CPK BB isoenzyme revealed higher levels after 30 minutes in SMA ligation with papaverine treated group than that in SMA ligation alone. Therefore it is supposed that peritoneal injection of vasodilator papaverine might be hazardous for the occlusive mesenteric ischemia in rats.

Evaluation of Myocardial Injury after Radiofrequency Catheter Ablation for Supraventricular Tachycardia by Means of Measurement of Myocardial Enzyme

OBJECTIVES: Radiofrequency(RF) ablation is an effective and low risk curative treatment for supraventricular arrhythmias. Catheter ablation produced cardiac lesions primarily through formation of coagulation necrosis. We evaluated the degree of myocardial injury after RF catheter ablation by means of serial measurement of myocardial enzyme. METHODS: Fifty-one patients with symptomatic supraventricular tachycardia were included. There were 32 men and 19 women(mean age. 39.5+/-15.4 years)All patients underwent electrophysiologic study to detect accessary pathway and ablation with radiofreguency current. A mean of 18.3+/-14.2 radiofrequency pulses were delivered. The pulses were at a power of 50 to 60 Volts for a duration of 20 to 30 seconds. Unipolar method and a 6F or 7F catheter with a 4 mm tip electrode was used. LDH, CPK and Ck-MB as a kind of cardiac enzyme were measured before and after ablation. RESULTS: 1) The concentration of LDH and CPK were elecated at 8 hours and 16 hours after ablation (p<0.05). 2) The concentration of CK-MB was elevated at 8 hours, 16 hours, 24 hours and 72 hours after ablation(p<0.05). 3) There was no correlation between the number of applications and amounts of radiofrequency current and rise in LDH, CPK, CK-MB concentration. CONCLUSION: The concentration of LDH, CPK and CK-MB were elevated after ablation but they were within normal limits. RF catheter ablation produced myocardial damage inevitably but were within normal limits. RF catheter ablation produced myocardial damage inevitably but minimally, then RF ablation is an effective and safe therapeutic modality for patients with symptomatic tachyarrhythmias.

Prognostic Indicators in Tibial Shaft Fractures ; Serum Creatine Kinase Acticity / 대한정형외과학회잡지

Serum creatine phosphokinase(CPK) levels were measured serially in 20 adults with closed tibial shaft fractures, CPK activity increased significantly after fracture(p < 0.01). High energy and delayed healing fractures had significantly higher levels of CPK than low energy and normally healing fractures, respectively. Thus, CPK determinations could be used to assess the severity of trauma and possible prognosis of the healing in tibial shaft fractures.

Protective effect of Yunnan folk medicine Rhodobryum roseum on experimental myocardial ischemia of rat / 中草药

Object To study the protective effect of Rodobryum roseum (Hedw) Limpr. on acute myocardial ischemia. Methods Rat acute myocardial ischemia models were prepared by ligating their left coronary arteries. Changes of their S-T segment was observed on lead Ⅱ dynamic ECG. Degree of ischemia was assessed by the extent of S-T segment elevation. Lactic dehydrogenase (LDH), creative phosphokinase (CPK), superoxide dismutase (SOD) and malondialdehyde (MDA) were determined at the same time. Results R. roseum can significantly alleviate S-T segment elevation, being most evident at the dose of 2 g/kg (P
