Monoester-diterpenoid alkaloids are the main bioactive components of Sini decoction, which is a well-known traditional Chinese medicine formula for the treatment of myocardial infarction (MI) and heart failure in China. In this work, an ultra-high-performance liquid chromatography-mass spectrometry

A 45-year-old woman was hospitalized to rule out acute myocardial infarction after coming to the emergency department with a complaint of substernal chest pressure. Her initial electrocardiogram indicated normal sinus rhythm with T-wave inversion and nonspecific ST changes suggestive of possible

Cases of acute myocardial infarction (AMI) that occur during pregnancy or postpartum are rarely reported. Ergot derivatives are known to induce the spasmodic contraction of coronary arteries. Administration of ergot derivatives can cause AMI, even in normal healthy people. In several reported cases,

BACKGROUND The overwhelming majority of myocardial infarctions result from atherosclerosis, generally with superimposed coronary thrombosis. The prevalence of patients who develop myocardial infarction and in whom subsequent angiography shows normal coronary arteries is approximately 5%. Many of

This is a report of a case of acute myocardial infarction which was probably induced by the oral administration of bromocriptine. A 55-year-old man was admitted because of suspected hypothyroidism and dwarfism. The endocrinological examination revealed primary hypothyroidism, and levothyroxine

Cocaine, the active alkaloid in coca leaf, is widely used as local anesthetic for otolaryngologic procedures. Our patient suffered an acute nontransmural myocardial infarction following clinical use of cocaine as topical anesthesia for nasal surgery, the first such case to be documented, to our

Dietary supplements containing ephedrine and other alkaloids related to ephedrine are largely consumed in various countries, with the purpose of energetic stimulation and weight loss. Despite the fact that it is not approved for marketing in Brazil, these products may be freely purchased over the

A patient with coronary artery disease suffered an acute myocardial infarction temporally related to chewing a betel nut. Alkaloids in betel nut, such as arecoline, may play a contributing role in coronary artery spasm due to parasympathomimetic effects on vessels with abnormal endothelium. Chewing

Although described in the literature as a powerful vasodilator, bromocriptine has been noted to cause vasospasm and hypertension. Two cases are presented where administration of bromocriptine in the puerperium was associated with massive myocardial infarction. These incidents suggest the possibility

Although cocaine abuse has declined in popularity in the United States, certain groups continue to use the drug at high rates. The teratogenicity of cocaine has been widely investigated in the newborn. We report a case of crossed renal ectopia in a term neonate whose mother practiced alkaloid

Menispermum dauricum rhizome has been widely used in China to treat various cardiovascular and thrombosis disorders. Some studies have reported that the phenolic alkaloids of Menispermum dauricum rhizome (PAM) have protective effects against brain ischemia injury, but the mechanism of this action

OBJECTIVE Because myocardial infarction is a major cause of morbidity and mortality worldwide, protecting the heart from the ischemia is the focus of intense research. Coptisine is an isoquinoline alkaloid extracted form Coptidis Rhizoma. This study aims to elucidate if coptisine is responsible for

BACKGROUND Berberine, an isoquinoline alkaloid isolated from the Berberis aristata, has been shown to display a wide array of pharmacological activities (hypoglycaemic and hypolipidemic). OBJECTIVE The present study was designed to investigate whether these pharmacological properties translate into
