Rosae Multiflorae Fructus Hot Water Extract Inhibits a Murine Allergic Asthma Via the Suppression of Th2 Cytokine Production and Histamine Release from Mast Cells.

Mast cell-mediated anaphylactic reactions are involved in many allergic diseases, including asthma and allergic rhinitis. In Korea, where it has been used as a traditional medicine, Rosae Multiflorae fructus (RMF) is known to have potent antioxidative, analgesic, and anti-inflammatory activities and to have no obvious acute toxicity. However, its specific effect on asthma is still unknown.

The effect of continuous epidural electrical stimulation on neuronal proliferation in cerebral ischemic rats.

Objective: To investigate the effect of electrical stimulation (ES) on the recovery of motor skill and neuronal cell proliferation.

Methods: The male Sprague-Dawley rats were implanted with an epidural electrode over the peri-ischemic area after photothrombotic stroke in the dominant sensorimotor cortex. All rats were randomly assigned into the ES group and control group.

Right-sided aortic arch with the retroesophageal left subclavian artery as the fourth branch.

We present a rare variation of the right-sided aortic arch with the retroesophageal left subclavian artery as the forth branch found in a cadaver of an 89-year-old Korean woman during a routine dissection. In this case, the first branch that arose from the ascending aorta was the left common carotid artery, which crossed ventral to the trachea in a left cephalic direction, followed by the right common carotid artery and then the right subclavian artery. Distal to these branches the aortic arch ran dorsally, passing between the esophagus and the vertebra.

Morphology of the human xiphoid process: dissection and radiography of cadavers and MDCT of patients.

Purpose: The purpose of this study was to evaluate the morphology of xiphoid process by dissection and using radiography of cadavers and multidetector computed tomography (MDCT) in patients.

Methods: The xiphoid processes of 41 cadavers were dissected and taken by radiography. Other 902 patients examined by MDCT were revealed by image post-processing used with multiple planar reconstruction, maximum intensity projection and volume rendering.

Choline acetyltransferase expression in rat prefrontal cortex and hippocampus after acute and chronic exposure to amisulpride, haloperidol, and risperidone.

Recently, there has been an increasing concern that atypical antipsychotics as well as typical ones may cause detrimental effects on cognitive function. Supporting evidence comes from many preclinical studies demonstrating that long-term administration of haloperidol, risperidone, and ziprasidone reduced choline acetyltransferase (ChAT) expression in rat hippocampus (HIP). However, to the best of our knowledge, no studies have examined the effects of amisulpride on ChAT expression in rats.

Effects of Anemarrhena asphodeloides on IgE-mediated passive cutaneous anaphylaxis, compound 48/80-induced systemic anaphylaxis and mast cell activation.

Background: We investigated the effect of Anemarrhena asphodeloides Bunge (Liliaceae) water extract (AAWE) on mast cell-mediated anaphylactic reactions. Mast cell-mediated anaphylactic reaction is involved in many allergic diseases, including asthma and allergic rhinitis. In Korea, where it has been used as a traditional medicine, AAWE is known to have antioxidant and anticancer activity.

Fetal topographical anatomy of the upper abdominal lymphatics: its specific features in comparison with other abdominopelvic regions.

Using semiserial sections from 19 human fetuses of 8-30 weeks gestation, we examined the topohistology of the upper abdominal lymphatics and compared it with that of the lower abdominal and pelvic lymphatics. The upper abdominal lymphatics were characterized by an intimate relationship with the peritoneal lining, a common mesentery for the celiac trunk and superior mesenteric artery (SMA). Lymphatic connections from the upper abdominal viscera to the paraaortic and paracaval areas followed two routes: (1) from the intestinal mesentery, along the peritoneum on the left aspect of the proximal SMA, via the chain of lymph follicles (LFs) lying along the retropancreatic fusion fascia, to drain into the LFs around the left renal vein; (2) from sites along the peritoneum on the posterior wall of the omental bursa, via the root of the hepatoduodenal ligament, to drain into LFs around the vena cava.

Lipoic acid suppresses compound 48/80-induced anaphylaxis-like reaction.

Alpha-lipoic acid (LA), a naturally occurring dithiol compound, is an essential cofactor in metabolic reactions involved in energy utilization. LA improves glycemic control, reduces diabetic polyneuropathies, atherosclerosis, and allergic inflammation. The effects of LA on mast cell-mediated anaphylactic reactions, however, are unknown.

Mast cells play a key role in Th2 cytokine-dependent asthma model through production of adhesion molecules by liberation of TNF-α.

Mast cells are well recognized as key cells in allergic reactions, such as asthma and allergic airway diseases. However, the effects of mast cells and TNF-α on T-helper type 2 (Th2) cytokine-dependent asthma are not clearly understood. Therefore, an aim of this study was to investigate the role of mast cells on Th2 cytokine-dependent airway hyperresponsiveness and inflammation.

The role of mast cells in atrial natriuretic peptide-induced cutaneous inflammation.

Atrial natriuretic peptide (ANP) is widely distributed throughout the heart, skin, gastrointestinal and genital tracts, and nervous and immune systems. ANP acts to mediate vasodilation and induces mast cell activation in both human and rats in vitro. However, the mechanisms of ANP-induced mast cell activation, the extent to which ANP can induce tissue swelling, mast cell degranulation, and granulocyte infiltration in mouse skin are not fully understood.

Human primitive meninges in and around the mesencephalic flexure and particularly their topographical relation to cranial nerves.

Development of the meninges in and around the plica ventralis encephali has not been well documented. A distinct mesenchymal structure, the so-called plica ventralis encephali, is sandwiched by the fetal mesencephalic flexure. We histologically examined paraffin-embedded sections from 18 human embryos and fetuses at 6-12 weeks of gestation.

Effects of 6-hydroxydopamine lesioning of the medial prefrontal cortex on social interactions in adolescent and adult rats.

Bilateral depletion of dopamine (DA) in the medial prefrontal cortex (mPFC) following local infusions of 6-hydroxydopamine (6-OHDA) was reported to affect mesolimbic DA neurotransmission and augment spontaneous and amphetamine-induced locomotion. However, the effects of 6-OHDA lesioning of the mPFC of adolescent rats have never been investigated. Given that dopaminergic neurons reach the peak of maturation during adolescence, we hypothesized that 6-OHDA lesioning of the mPFC during adolescence would have greater impact on subsequent behavioral parameters than would such lesioning during adulthood.

HCWE has been used as a traditional medicine in Korea and is known to have an antioxidant and anti-cancer activities.

Inhibitory effects of Morus alba on compound 48/80-induced anaphylactic reactions and anti-chicken gamma globulin IgE- mediated mast cell activation.

We investigated the effects of hot-water extract from the root bark of Morus alba (HEMA) on anaphylactic reactions. Using in vitro and in vivo experiments, we examined whether HEMA could inhibit compound 48/80-induced systemic anaphylactic shock and anti-chicken gamma globulin (CGG) IgE-mediated rat peritoneal mast cell activation. HEMA significantly inhibited systemic anaphylaxis induced by the compound 48/80 in mice.

Hypoplasia of the left portal vein territory of the human liver: a case study.

Although reports of hypoplasia or absence of the liver of left lobe are not few, descriptions of the intrahepatic vessels are rare but valuable for discussion of the pathogenesis. The present report demonstrates a case of the left surgical lobe hypoplasia that is characterized by 1) the scar-like lobe with few parenchymal tissue and dilated bile ducts, 2) no Spiegel's lobe with the portal vein stuck to the inferior vena cava, 3) unusual configurations of the right hepatic vein and the 8th segmental portal vein branch, 4) the hepatic groove on S8, and 5) the trifurcation pattern of the portal vein primary division. According to the macroscopic and histological observations, we hypothesized that the secondary abnormal peritoneal fusion occurred in utero and/or during the postnatal growth, and that it involved the left portal vein and other adjacent structures, resulting in severe atrophy of the left surgical lobe.
