Blood and Immunolgy Module has been designed to define the scope of Knowledge/ Skills/ Attitudes of a first year medical student of the Basic Medical Sciences i.e. Anatomy, Physiology and Biochemistry with the introduction to the Clinical Sciences and an emphasis on body defense mechanisms and immunological disorders. This is the second module of 1st year of MBBS and will be followed by a block assessment. Blood and Immunology module is a 4 weeks theme based module, the contents of which will be thought in lectures, SGDs, DSLs and practical work. Blood and Immunology module consists of the following themes: 1) Pallor and Fatigue (Duration: 1 week) 2) Fever (Infection and Immunity) (Duration: 2 weeks) 3) Excessive Bleeding (Duration: 1 week) General Learning Outcomes 6 At the end of this module, the students will be able to; 1) Identify & describe the various cellular and non-cellular components of blood in relation to its Anatomy, Physiology & Biochemistry 2) Describe structure, synthesis and degradation of Hemoglobin 3) Describe the regulatory mechanisms of normal hemostasis and coagulation 4) Describe the conditions associated with dysfunction of cellular and non-cellular components of blood 5) Describe the basic characteristics of immune system. 6) Discuss the structure, functions and biochemical aspects of the Lympho-reticular system. 7) Explain the principles and clinical significance of ABO/RH blood grouping system 8) Explain the pathophysiology of various bleeding disorders 9) Identify the role of pharmacology in anemia and bleeding disorders 10) Describe the basics of communication skills 11) Describe different types of stress, and its behavioral aspects 12) Carry out practical work as instructed in an organized and safe manner 13) Make and record observations accurately. 14) Identify slide of Lymph node, thymus, tonsils and spleen under microscope 15) Identify slide of Gut associated lymphoid tissue 16) Determine percentage of formed blood elements. 17) Identify RBC and should be able to do its counting on counting chamber and to know normal values. And also classify Anemia morphologically. 18) Determine the Hemoglobin with the apparatus and have knowledge of normal and abnormal value. 19) Identify WBC morphology and its different types, should be able to count them on counting chamber and to know the normal values. Diagnostic importance of each WBC. 20) Identify Platelets and should be able to do its counting on counting chamber and to know normal values. Its diagnostic importance in relation to bleeding disorders 21) Perform bleeding time and clotting time and to know normal values and its diagnostic importance in relation to bleeding disorders. 22) Perform Blood groups typing and Rh factor. 7 23) Perform ESR and to know its normal value and prognostic importance. Theme-1 (Pallor and Fatigue) Introduction 8 This theme focuses on composition of blood and functions of its various components. The chemistry of hemoglobin, the stages, factors and regulation of erythropoiesis will be discussed in detail. Biochemical aspects of B-complex vitamins and folic acid will be explained. This will be followed by morphological and etiological classification of anemias and their prevention and drug treatments. In the end various hemoglobinopathies and thalassemia will be discussed.
