    Original Article Toluidine Blue Stain and Crystal Violet Stain Versus H&E Stain in the Diagnosis of Hirschsprung’s Disease : A Study in Sulaimani City in Kurdistan/Iraq Hadeel A. Yasseen Department of pathology, School of Medicine, University of Sulaimani. Iraq Keywords: Hirschsprung’s Disease, Ganglion Cells, Cresyl Violet, Toluidine Blue, Mast Cells ABSTRACT Background: Hirschsprung’s Disease (HD) is a congenital disorder of the colon in which certain nerve cells, known as ganglion cells are absent. Setting and Design: To demonstrate the efficacy of Cresyl Violet and Toluidine blue (Tb) special stains in the identification of ganglion cells in suspected Hirschsprung’s disease and to find other adjuvant histological criteria for the diagnosis. Method: In Sulaimani Teaching Hospital and Pediatric teaching hospital in Sulaimani Governorate/ Kurdistan-Iraq a total of fifty non selected cases biopsied for suspected HD were stained with hematoxylin and eosin (H&E) stain and divided into two groups: HD and-non-HD. All cases then should be stained with Tb special stain to identify ganglion cells and to count mast cells in the submucosa. Cases were stained with Cresyl Violet special stain to identify ganglion cells. H&E- and Tb-stained sections were examined for the presence or absence of hypertrophic nerve fibers in the submucosa. Results: Both Cresyl violet and Tb stains were superior to H&E in the identification of ganglion cells with no statistically significant difference between the two stains. Mast cell count in the submucosa has no important effect on diagnosis while nerve bundle hypertrophy was found to be associated with absence of ganglion cells in Hirschsprung disease.

Getting to know its normal morphological changes during aging are of great importance for the interpretation of intestinal motility disorders. The aim of our histomorphometric study was to reveal detailed characteristics of myenteric plexus, cell number, orientation, properties of as well as age-related changes in the human jejunum. Materials and methods: We examined the myenteric ganglia in the proximal jejunum specimens obtained from 30 human cadavers aged from 20 to 84 years. Tissue samples were classified into three age groups: 20–44, 45–64 and 65–84 years. After standard histological preparation, specimens were stained with haematoxylin and eosin method, Cresyl-Violet and silver nitrate (AgNO3) by the method of Masson Fontana. In addition to standard staining methods we use and enzyme histochemical method for acetylcholinesterase. Morphometric analysis of all the specimens was performed, using a multipurpose test system M42.

The promise of such recordings has inspired great progress in methods for surgically implanting large numbers of metal electrodes into intact rodent brains. However, methods for localizing the precise location of these electrodes have remained severely lacking. Traditional histological techniques that require slicing and staining of physical brain tissue are cumber- some and become increasingly impractical as the number of implanted electrodes increases. Here we solve these problems by describing a method that registers 3D computed tomography (CT) images of intact rat brains implanted with metal electrode bundles to a magnetic resonance imaging histology (MRH) atlas.

Email: [email protected] Received: 18 Jun 2012, Revised and Accepted: 26 July 2012 ABSTRACT Ketamine abuse is on the increase in Malaysia. Neurodegenerative change following ketamine use results in debilitating behavioural and cognitive dysfunctions. These changes are thought to be the consequences of network and cellular disorganization and degeneration in the brain involving areas such as hippocampus. Ketamine works by blocking NMDA receptor and hence ketamine research has value in study on NMDA-related neurological disorders such as schizophrenia. This work study the histological change in rats brain which was exposed to ketamine and the effect of treating ketamine-exposed rats with haruan traditional extract (HTE) a substance which has been shown to have positive neuroregenerative function in cell culture study. The changes were studied using cresyl violet and parameters such as pathological score, dead cell count and degenerative change were evaluated. It was demonstrated that ketamine influences these parameters in exposure length-dependent manners and degenerative change could be ameliorated by supplementation with haruan therapeutic extract (HTE) pre-damage induction but not post-damage induction.

  • Exercise Mitigates Alcohol Induced Endoplasmic Reticulum Stress
    www.nature.com/scientificreports OPEN Exercise Mitigates Alcohol Induced Endoplasmic Reticulum Stress Mediated Cognitive Impairment Received: 30 January 2018 Accepted: 13 March 2018 through ATF6-Herp Signaling Published: xx xx xxxx Akash K. George, Jyotirmaya Behera, Kimberly E. Kelly, Nandan K. Mondal, Kennedy P. Richardson & Neetu Tyagi Chronic ethanol/alcohol (AL) dosing causes an elevation in homocysteine (Hcy) levels, which leads to the condition known as Hyperhomocysteinemia (HHcy). HHcy enhances oxidative stress and blood- brain-barrier (BBB) disruption through modulation of endoplasmic reticulum (ER) stress; in part by epigenetic alternation, leading to cognitive impairment. Clinicians have recommended exercise as a therapy; however, its protective efect on cognitive functions has not been fully explored. The present study was designed to observe the protective efects of exercise (EX) against alcohol-induced epigenetic and molecular alterations leading to cerebrovascular dysfunction. Wild-type mice were subjected to AL administration (1.5 g/kg-bw) and subsequent treadmill EX for 12 weeks (5 day/week@7–11 m/ min). AL afected mouse brain through increases in oxidative and ER stress markers, SAHH and DNMTs alternation, while decreases in CBS, CSE, MTHFR, tight-junction proteins and cellular H2S levels. Mechanistic study revealed that AL increased epigenetic DNA hypomethylation of Herp promoter. BBB dysfunction and cognitive impairment were observed in the AL treated mice. AL mediated transcriptional changes were abolished by administration of ER stress inhibitor DTT. In conclusion, exercise restored Hcy and H2S to basal levels while ameliorating AL-induced ER stress, diminishing BBB dysfunction and improving cognitive function via ATF6-Herp-signaling. EX showed its protective efcacy against AL-induced neurotoxicity.

This paper reports the standardization of the time schedules used for processing and paraffin embedding of vertebrate brains having different sizes. Some modifications of the Nissl and Klüver-Barrera staining methods are proposed. These modifications include: 1- a Nissl stain solution with a rapid and efficient action and easier differentiation, 2- the use of a cheap microwave oven for the Klüver-Barrera stain. These procedures have the non negligible advantage of permitting the performance of Nissl and Klüver-Barrera staining methods in about five and fifteen minutes respectively. The proposed procedures have been tested in nervous tissues obtained from fishes, amphibians, reptiles and mammals of different body sizes. They are the result of long experience in preparing slides for comparative studies. Serial sections of excellent quality were regularly produced in all the specimens studied. These standardized methods are simple, rapid and may be recommended for routine use in laboratories. INTRODUCTION Practical problems often appear when the classical histological procedures for studying the nervous system are used. Such difficulties mainly arise when large brains must be serially sectioned. Perfect serial sections are mandatory in the case of nervous structures due to their complex organization that varies grossly from region to region.
