Extramedullary hematopoiesis (EH) is defined as hematopoiesis occurring in organs outside of the bone marrow; it occurs in diverse conditions, including fetal development, normal immune responses, and pathological circumstances. During fetal development, before formation of mature marrow, EH occurs in the yolk sac, fetal liver, and spleen. EH also occurs during active immune responses to pathog...

Eclosion hormone (EH) is a 62-amino acid neuropeptide that initiates the ecdysis behavior of insects. The EH-encoding gene of the tobacco hornworm, Manduca sexta, was isolated by using a designed 72-mer oligonucleotide probe. Sequence analysis of this gene and its corresponding cDNA showed that the EH gene is 7.8 kilobases and consists of three exons. Exon I is totally nontranslated; exon II co...

Objective/Hypothesis Meniere's disease (MD) is a common inner ear disease characterized by repeated episodic vertigo, fluctuating sensorineural hearing loss, and tinnitus. Its pathology is defined as endolymphatic hydrops (EH) in the inner ear and EH has been hypothesized to correlate with the clinical symptoms of MD. We presented the dynamics of in vivo EH in MD patients during medical treatme...

OBJECTIVE The aim of our study is to determine clinical factors and sonographic findings associated with endometrial hyperplasia or cancer (EH+) in premenopausal and perimenopausal women. METHODS A total of 14,340 transvaginal ultrasonography examinations of 9,888 healthy premenopausal and perimenopausal women were included in this retrospective study. One hundred sixty-two subjects underwent...

Aminopeptidase A (APA) cleaves the N-terminal aspartyl acid residue of angiotensin II (Ang II) to produce angiotensin III (Ang III). It has been reported that the APA knockout mouse exhibits elevated blood pressure. Therefore, the APA gene is thought to be a susceptibility gene for essential hypertension (EH). However, extensive studies have yet to define the relationship between the APA gene a...

Korean native honey (KNH) is much more expensive than European honey (EH) in Korea, because KNH is a favored honey which is produced less than EH. Food fraud of KNH has drawn attention of the government office concerned, which is in need of a method to differentiate between KNH and EH which are produced by the Asiatic honeybee, Apis cerana and the European honeybee, Apis mellifera, respectively...

Entamoeba histolytica (Eh) is an extracellular protozoan parasite of humans that invades the colon to cause life-threatening intestinal and extra-intestinal amebiasis. Colonized Eh is asymptomatic, however, when trophozoites adhere to host cells there is a considerable inflammatory response that is critical in the pathogenesis of amebiasis. The host and/or parasite factors that trigger the infl...

OBJECTIVE/HYPOTHESIS This study aimed at investigating the correlation between a battery of diagnostic symptoms of definite Meniere's disease (MD) and the degree of endolymphatic hydrops (EH) in the inner ear. STUDY DESIGN Prospective study. METHODS Fifty-four patients diagnosed with unilateral definite MD were enrolled in the study. The hearing levels of all patients at the low, middle, an...

Duchenne muscular dystrophy (DMD) is a fatal disease where over 90% of patients succumb to respiratory or cardiac failure. Sleep apnea and sleep disordered breathing (SDB) are noted in a plurality of DMD patients, and the resulting nocturnal episodic hypoxia (EH) cannot be ruled out as a contributing factor to cardiac and respiratory dysfunction. In this study, we investigated the impact of lon...

Epithelioid hemangioma (EH), also known as angiolymphoid hyperplasia with eosinophilia, may affect the eyelids and orbit, mimic idiopathic orbital inflammation, and respond poorly to corticosteroids. We describe a patient with chronic, bilateral orbital EH unresponsive to corticosteroids. Histopathologic analysis showed lobular vascular proliferations containing plump endothelial cells with sur...
