Balantidum Coli

-
    Balantidum Coli
    - Lives in small intestine of human, pigs, and monkeys.

    Morphology:
    - Parasite exist in 2 phases:
    a. Trophozoite
    b. Cyst


    A. Trophozoite
    - Oval in shape.
    - Anterior end is narrow, with groove leading to mouth.
    - Posterior ends is broad, with excretory opening.
    - Cell is covered with (short - cilia).
    - Cilia that line the mouth part is (large - cilia).
    - Macro nucleus is kidney shaped.
    - Micro nucleus is small, and round shaped.

    B.Cyst:
    - Spherical / oval in shape.
    - Surrounded by thick and transparent double layered wall.
    - Macro nucleus, Micro nucleus, and Vacuoles are present in the cyst.

    Life Cycle:
    - B.Coli passes its life cycle in one host only.
    - Pig is the natural host and man is incidental host.
    - Cyst is the Infective form.


    Pathogenesis:
    - Diarrhoea
    - Nausea, and Vomiting.
    - Anorexia.

    Laboratory Diadnosis:
    1.Specimen:
    - Faeces
    - Biopsy material
    - Scraping from intestinal ulcer

    2.Stool Examination:
    - Wet mount for trophozotie and cyst
    - Iodine mount shows Trophozoite in yellowish brown.
    - Cyst can be recognized by presence of large macro nucleus

    3.Biopsy:
    - Specimen taken from intestinal ulcer can also be examined under diagnosis.

    Treatment:
    - Metronidazole
    - Tetracycline

BONE MARROW EXAMINATION

Image
  BONE MARROW EXAMINATION It is the only method of correctly diagnosing diseases of blood. Sites of bone marrow aspiration: The following sites are selected for bone marrow aspiration: Sternum Iliac crest and upper end of tibia in children. Requirements: A special bone marrow needle (salah or klima needle) along with stilette Local anesthesia (Lignocaine) 2 to 5 ml syringe Glass slides Absolute methanol Formal ethanol Procedure: The site of puncture is usually sternum. Sterilize the selected site with soap water, iodine and finally with alcohol. The Site is anesthetized locally using lignocaine. Skin and subcutaneous tissues are punctured using sterilized bone biopsy and needly. When needle reaches periosteum, guarded needle is pushed further about 5 mm. Now the needle is fixed tightly in position. Now the needle is further pushed with boring motion into the cavity of bone. The stilette is removed and well fitted 2-5 ml syringe is used About 0.3 ml of bone marrow contents are sucke...

Histopathology Technique - Part 2 (Tissue processor)

-
Image
Tissue Processing:       Nowadays all the process of fixation, dehydration, clearing, and impregnation are carried out in a special equipment which is known as automated tissue processor. It can be a open (hydraulic) system or a closed (Vacuum) type. In the open type, the tissue processor has 12 - 16 glass jars for formalin, ascending grades of alcohol, xylene and thermostatically- controlled two paraffin wax baths to keep paraffin wax in molten state. Tissue moves automatically by hydraulic mechanism from one jar to another after fixed time schedule and the whole process takes 16-22 hours. In closed type of tissue processor, tissue cassettes are placed in a single container while different processing fluids are moved in and out sequentially according to electronically programmed cycle. The closed or vacuum  processor has the advantage that there is no hazard of contamination of the laboratory by toxic fumes unlike in open system. In addition, heat and ...

Bleeding Time and Clotting Time

-
Image
Introduction: For the investigation of a case of bleeding disorder,clinical history is very important. An accurate clinical and family history will often give an important time-saving clue to the nature of underlying bleeding disorder. 􀂄 Appearance of purpuric spots or bruises over minimally injured surface suggests an abnormality of the vascular wall. 􀂄 Continuous bleeding from mucous membranes, cuts, wounds, deeper haematomas or bleeding into the joints will suggest a defect in the blood coagulation system. 􀂄 Excessive bleeding following delivery, or retention of dead foetus, or oozing following extensive surgery, suggest the possibility of fibrinogen depletion or presence of circulating anticoagulant agents. 􀂄 History should also be taken about the ingestion of antiplatelet drugs such as aspirin. Two of the commonly used screening tests, bleeding time and whole blood clotting time, are discussed below. BLEEDING TIME  (BT) Bleeding time is duration of bleeding from a standard...
