Learning outcomes

1. Define medical and allied sciences2. Clarify the relationship between medical

competency and the contribution of medical and allied sciences, professional skills and attitude.

Page 3: Biomedical Science

Enabling outcomes

1. Be able to knows what is BS2. Be able to describe that BS is concerned to

integration of a wide range of subject to understand the biology of disease.

3. Be able to describe the role of BS as science of causes, diagnoses and treatment of disease.

Page 4: Biomedical Science

Lecture

• Introduction: including enabling outcomes 1 and 2

• The role of BS in supporting to know the causes, diagnose and treatment of diseases scientifically (Anatomi/Histology, Biochemistry, Physiology and Farmacy/Pharmacology) (Enabling outcomes 3)

Page 5: Biomedical Science

Learning activities

1. Lecture (presented by one of the team members) All lecturers in the team are order to make an abstract of their lecture (no more than 2 pages), completed by essential reference (learning resources), and learning task, in order to support the role of each department as the part of BS team.

Learning taskCase for discussed.

1. 55 years woman visited her family physician , complain chest pain in left part oh her chest, specially when she exercised. She is also complain lost her weight more than 8 kg in a month. She eat and drink more than usual. On laboratory examination found FBS 150 mg%, lipid profile increase (total cholesterol 240 mg%, LDL chol 200 mg%, HDL chol 175 mg% and tri glyceride 300 mg% blood pressure 150/90 mmHg. Her family doctor diagnose as DM with hypertension and hyperlipidemiea with TIA. Her doctor treat her with glycasid, for DM, captopril and statin for hypertention and dislipidemia.

Learning task

1. Where is the normal location of the heart in our body; heart border; What is heart rate and heart function.

2. Why does she lost her body weight, while she eat and drink more than usual.

3. Are the Laboratory finding is normal?. If not where are the disorder.

4. Are sign and symptom lead you to diagnose the disease. What it is ?

Introduction Medical curriculum in Udayana Fac of Medicine. 1. Traditional C, Depart. Based approach C (preclinical

and clinical years) Criticized – lacking in the skill and attitude required to practice their profession.

2. In the response of these challenges Out come-based C for biomedical sciences

BMS

• BMS is concerned with the integration of a wide range of subjects to understand the biology of disease.

• Biology in this sense means predominantly anatomy/histology, physiology, biochemistry, genetic, immunology, microbiology, pharmacology and molecular biology related to human disease

Page 10: Biomedical Science

• More specific knowledge of disease process comes from the study of specialized biology : cellular pathology, clinical biochemistry, clinical immunology, medical microbiology, hematology, transfusion science .

• This enables a BM scientist to understand the science of causes, diagnosis and treatment of disease.

Page 11: Biomedical Science

• Clinical sciences is the science you need in your private practice to diagnose and treated and preventions of patients problem through history of disease/anamnesis, and physical examination.

• Its have to be support by BMS and allied sciences.

Page 12: Biomedical Science

Allied sciences

• Sciences which is important in supporting the management of preventing, diagnosis and treatment of disease.

• Together with BMS and clinical sciences, physician will manage the disease holistically and scientifically

• Example : communication, psychological science and other behavioral sciences.

Page 13: Biomedical Science

Characteristic of BMSThe important characteristic of BMS:1. Always change life long education2. Tights inter relationship one another3. Are always in the forefront of modern science

rapidly evolving subject and highly relevant to investigating and understanding current controversies.

4. Tight relationship to clinical and allied sciences on solving medical cases

5. Graduate will have a wide range of employment.

Page 14: Biomedical Science

Advantages of learning BMS

• BMS involve a multidisciplinary approach to the study of human disease.

• Graduates must have knowledge of how disease develop and how they affect the normal function of the human body.

• They will have awareness of the development of new methods for diagnosis, treatment and prevention of disease.

Page 15: Biomedical Science

Attributes of Graduates

Think creatively and critically.Able to problem-solve.Communicate effectively.Have professional conduct.Able to work in teams.Understand how scientific research is conducted, applied, and funded.

Case study• A forty years old patient attend his family doctor with

complain of reduce body weight in six month later. She has drinking a lot of water, but also pass a lot of water. His appetite increase. He is also complaining about head ache. On the laboratory examination found, fasting blood sugar 180 mg%, and 300 mg% 2 hours after meal. Keton bodies of urine increase and HbA-1c = 7.5 His blood pressure 170/100 mmHg.He is also complain palpitation especially when exercise His doctor diagnosed him as Diabetic and hypertension. The doctor cured him with gliclazide for his diabetic and Captopril for his hypertension and medicine for her heart.

Page 17: Biomedical Science

• Please learned the case by yourself (independent learning) using interdisciplinary approach of BMS

• Secondly discussed on your SGD. Use the learning tasks as guide lines on your discussion. Debate if there are any difference opinion in solving the problem.

• Finally report the result of your SGD in plenary session.

BIOCHEMICAL VIEWOF BMS

Page 23: Biomedical Science

Biochemical view of BMS

1. Metabolism of CH, Lipid, protein and xenobiotic

2. Energy production

3. Normal value of body chemistry

Page 24: Biomedical Science

Metabolism.

• Metabolism is all enzymatic reaction that occur in the cells

• Divided into 2 catagories anabolism and catabolism

• Anabolism is energy required reaction• Catabolism is energy yielding reaction

Page 25: Biomedical Science

• Metabolism of Carbohydrate including:glycolysisconversion of pyruvate to acetyl CO-AKreb-cycle/TCA cycleOxidation phosphorylationEnergy production

Page 26: Biomedical Science

• Lipid metabolism• Lipid break to glycerol and fatty acid• Fatty acid beta, alpha and omega oxidation

to produce acetyl-CoA Kreb cycle Oxidation phosphoryration energy.

• Protein amino acid. (glucogenic, ketogenic, gluco-ketogenic) Kreb cycle Oxid phosp energy

Energy yielding in catabolism

• Catabolism of C-H, lipids, aa to a simpler end-product such as CO2, H2O and amonia is accompanied by the synthesis of ATP.

• ATP is utilized for various cellular functions such as :

• synthesis of protein,RNA,DNA for growth, adaptation and repair,• synthesis of fat and glycogen,• performance of mechanical work,• active ion transport, • absorptions of nutrients against the gradient.
