Presentation transcript:

Diabetes

Spec (e) the differences between Type 1 and Type 2 diabetes mellitus To include the causes of Type 1 and Type 2 diabetes and the treatments used for each. HSW12 (f) the potential treatments for diabetes mellitus. To include the use of insulin produced by genetically modified bacteria and the potential use of stem cells to treat diabetes mellitus.

Learning Objective Success Criteria Know about diabetes mellitus Compare and contrast the causes & treatments of Type 1 & Type 2 Discuss the potential treatments of diabetes with reference to GM bacteria and stem cells

Starter: Key Terms Match key terms and definitions Number this, for students to jot down answers!

Diabetes Mellitus Disease in which blood glucose concentrations cannot be controlled effectively Using the fact sheet answer the questions on the worksheet

Type II Type I Non-insulin dependent Insulin dependent Description Type I Type II Insulin dependent Starts in childhood Beta cells damaged Virus Autoimmune Can’t make enough insulin Can’t store excess glucose Non-insulin dependent Generally adults Obesity High sugar diet Asian/Afro-Caribbean Family history Still make insulin Receptors decline

Type II Type I Insulin Injections Control of diet Treatment Type I Type II Insulin Injections Control of diet Later can be controlled by drugs that slow down absorption of glucose

Task: In groups interpret the data

Genetically Modified Bacteria Copy of human insulin gene put into bacteria Bacteria make human insulin Less chance of developing tolerance Less chance of rejection Less chance of infection Cheaper Less ethical issues

Potential Treatment: Stem Cells Precursor cells found in pancreas of adult mice If same in human these cells could be used to replace damaged beta cells in type I diabetes
