5Preface
Looking into the changed curriculum policy of DCI for BDS 1st year where physiology and biochemistry are considered as a single subject, I had felt a great need for a good workbook of practical hematology for BDS 1st year. This workbook of practical hematology is in line with the curriculum policy of DCI.
Great emphasis has been laid on the applied aspects of hematology because our aim is not to train technicians; but its aim is to make would-be dentists to learn the principles of hematology and to use them in their future clinical practice. Though students should be concerned about acquiring the necessary skill, more so in recording the results and interpreting them.
Earlier BDS 1st year students had to depend on practical physiology books or manuals which were meant for MBBS. After reading these manuals, they used to perform practical and record their results in separate practical files or note books. But the workbook Practical Hematology for BDS serves the purpose of textbook, manual as well as workbook. It has covered all the practical aspects of hematology.
The workbook is divided into two sections:
- Practical section
- Demonstrations.
The Practical section includes those practicals which are required to be included in the University practical examination. They are to be performed by the students during practical classes to acquire skills.
Demonstrations are to be shown to the students during practical classes. However, these demonstrations are not required to be included in the University examinations but questions based on this would be given in the form of charts, graphs and calculations for interpretation by the students. All the practicals are covered under the following sections.
Objectives: A set of objectives has been given at the beginning of each practical. They are intended to inform the student what they must learn from a particular exercise. The student should go through them before starting the practical and should again look at them after completing the practical, to assess whether he has acquired the necessary skill and the knowledge. The objectives covered in this book are based on what a student must know but they do not limit what he may know. Medical field being so vast, there is no end to knowledge so teachers can add on these minimum objectives.
Introduction: It covers the basic knowledge of the topic on which the practical is based.
Method: Keeping in view the fast-growing world of medical science, we want our students to remain abridged with the latest methodology used in hematology, so this section covers different methods employed for performing a particular practical. Thereafter, the detail of one particular method (required by BDS student to know) is discussed in detail. The principle of the method, all the factual knowledge and the technical data of the apparatus to be used is discussed, the whole procedure is dealt with in detail in a stepwise manner; and immediately after the procedure, sound and updated precautions to be observed are given to avoid fruitless work. After that the, way to record observation, perform calculations (if any) and express result is described.6
Besides the technical details, a clear concept regarding the theoretical background of the experiment performed, its importance and uses, and clinical correlation is covered under discussion. Well-labeled diagrams and photographs of the apparatus are provided along with the text for proper understanding.
To overcome the need of using additional practical file, work space has been provided at the end of each chapter where students will record observations, perform calculations and give the results. Important viva questions are also given to help students prepare for their examination.
As far as possible, each statement included in the workbook is drawn from some well recognized source and care has been taken to cover every aspect of practical hematology BDS 1st year curriculum.
I must express my gratitude to my husband, Mr Ajay Kumar, for his endless support and understanding. I express my thanks to Jaypee Brothers Medical Publishers (P) Ltd for bringing out this workbook in excellent form. I request all the students and the teachers using this workbook to evaluate it with open mind and give their valuable suggestions.
