Study Notes
PUPD and Diabetes Mellitus
- PUPD: Polyuria (increased urination) and Polydipsia (increased drinking)
- Diabetes Mellitus: body can't produce enough insulin or insulin isn't effective

Hormones involved in Glucose Homeostasis
- Insulin:
- Stimulus: increased glucose concentrations, parasympathetic nerve activity
- Type of cell: islets of Langerhans, beta cells
- Effect: binds to cell surface receptors, activates downstream signaling, causes glycogen synthesis, decrease in glycogenolysis and gluconeogenesis
- Glucagon:
- Stimulus: decreased glucose concentrations, sympathetic nerve activity
- Type of cell: islets of Langerhans, alpha cells
- Effect: binds to cell surface receptors, activates downstream signaling, causes mobilization of glucose from liver, increase in glycogenolysis and gluconeogenesis
- Adrenaline (Epinephrine):
- Stimulus: Acetylcholine release from preganglionic nerve fibers
- Type of cell: adrenal medulla, chromaffin cells
- Effect: binds to cell surface receptors or nuclear receptors, activates downstream signaling, increases blood glucose concentrations

Metabolic Disturbances in Diabetes Mellitus
- Reduced insulin production (Type 2) or complete insulin deficiency (Type 1)
- Body cells cannot use glucose, resulting in hyperglycemia and glucose in urine

- Storage vessel: sterile container, glass non-anticoagulant tubes
- Sample storage: immediate refrigeration, maximizes cell preservation and minimizes bacterial growth
Venepuncture in the Dog
- Jugular venepuncture: hold off jugular vein, apply alcohol, part hair to visualize vein
- Cephalic venepuncture: stroke the vein, apply alcohol, part hair to visualize vein
Complications of Diabetes Mellitus
- Polyuria, polydipsia, polyphagia, weight loss
- Cataracts, weakness, decreased appetite, hepatomegaly, lethargy
- Diabetic neuropathy, diabetic ketoacidosis, hyperosmolar hyperglycemic state### Insulin and Glucagon
- Insulin secretion:
- Stimulated by increased glucose concentrations and parasympathetic nerve activity
- Produced by Beta cells in the islets of Langerhans
- Binds to cell surface receptors, activating downstream signalling in the cell
- Causes glycogen synthesis, decrease in glycogenolysis, and decrease in gluconeogenesis
- Glucagon secretion:
- Stimulated by decreased glucose concentrations and sympathetic nerve activity
- Produced by Alpha cells in the islets of Langerhans
- Binds to cell surface receptors, activating downstream signalling in the cell
- Causes mobilisation of glucose from liver, increasing glycogenolysis and gluconeogenesis
Adrenaline (Epinephrine)
- Secretion:
- Stimulated by acetylcholine release from preganglionic nerve fibres
- Produced by chromaffin cells in the adrenal medulla
- Binds to cell surface receptors or nuclear receptors
- Effects similar to glucagon, increasing blood glucose concentrations
Growth Hormone (GH)
- Stimuli:
- Hypoglycemia (low blood sugar)
- Main regulator: Growth Hormone-Releasing Hormone (GHRH)
- Secretion:
- From the hypothalamus, stimulating somatotrophs in the pituitary to release GH
- Produced by somatotrophs in the anterior pituitary
- Effects:
- Stimulates liver, releasing Insulin-like Growth Factor-1 (IGF-1)
- IGF-1 binds to receptors on cell membranes, triggering downstream signalling
- Increases glucose production through gluconeogenesis and glycogenolysis
Progesterone
- Secretion:
- From the hypothalamus, stimulating LH and FSH
- Produced by gonadotrophs in the anterior pituitary gland
- Effects:
- Binds to cytosolic or nuclear receptors
- Activates protein synthesis of specific proteins
- Diverts glucose utilization away from muscle and fat, promoting glycogen storage in the liver
Glucocorticoids (mainly Cortisol)
- Secretion:
- Stimulated by stress, higher brain centers, and hypothalamus
- Produced by the adrenal cortex, zona fasciculata
- Lipid-soluble, diffusing through plasma membranes, binding to cytosol receptors
- Influences transcription of specific genes
- Stimulation of hepatic gluconeogenesis
Diabetes Mellitus
- Definition: Chronic disorder of carbohydrate metabolism due to relative or absolute insulin deficiency
- Effects:
- Hyperglycemia (high blood sugar)
- Glucosuria (excess glucose in urine)
- Polyuria (increased urination) and polydipsia (increased drinking)
- Weight loss
- Lethargy
Glucosuria
- Definition: Excess glucose in the urine
- Causes:
- Diabetes mellitus
- Increased glucose in the blood exceeding the kidney's capacity to reabsorb
- Effects:
- Osmotic diuresis (increased urine production)
- Polyuria and polydipsia
Polyuria and Polydipsia (PUPD)
- Definition: Increased urination and drinking
- Causes:
- Diabetes mellitus
- Diabetes insipidus
- Cushing's disease
- Other conditions
- Effects:
- Increased urine production
- Increased thirst
- Accidents around the house
Diabetes Insipidus
- Definition: Disease where the kidneys are unable to store water
- Effects:
- Extreme thirst
- Polyuria and polydipsia
- No effect on blood sugar levels
Serum Fructosamine
- Definition: Measure of average blood glucose concentration over the previous 2-3 weeks
- Clinical utility:
- Assesses glycaemic control in dogs with diabetes mellitus
- Not affected by short-term increases in serum glucose
- Sample collection and analysis:
- Blood sample (plasma or serum)
- Nitroblue tetrazolium assay
- Interpretation: High levels indicate diabetes mellitus### Endocrine System
- Adrenal Medulla: receptors are acetylcholine and postganglionic is noradrenaline on alpha and beta adrenergic receptors
- Effects of Epinephrine: increases blood glucose concentrations, promotes hepatic glycogenolysis and gluconeogenesis
Growth Hormone (GH)
- Stimuli: hypoglycemia can trigger secretion, but the main regulator is Growth Hormone-Releasing Hormone (GHRH)
- Secretion: from the hypothalamus, GHRH stimulates somatotrophs in the pituitary to release GH
- Effects: GH stimulates the liver, releasing Insulin-Like Growth Factor-1 (IGF-1), which binds to receptors on the cell membrane, triggering downstream signalling
Progesterone
- Secretion: from the hypothalamus, Gonadotropin-Releasing Hormone (GnRH) stimulates LH and FSH
- Type of cell that produces: gonadotroph in the anterior pituitary gland
- Effects: binds to cytosolic or nuclear receptors, activating protein synthesis of specific proteins
- Effects on carbohydrate metabolism: diverts glucose utilization away from muscle and fat to other tissues, promotes glycogen storage in the liver
Glucocorticoids (mainly cortisol)
- Secretion: stress stimulates the hypothalamus, which releases ACTH, stimulating the adrenal cortex
- Type of cell that produces: adrenal cortex, zona fasciculata
- Effects: lipid-soluble, diffuses through the plasma membrane, binds to cytosolic receptors, influencing transcription of specific genes
- Effects on carbohydrate metabolism: stimulates hepatic gluconeogenesis, increases glucose production
Pancreas

- Three parts: right lobe, left lobe, and body
Diabetes Mellitus
- Definition: a chronic disorder of carbohydrate metabolism due to relative or absolute insulin deficiency

Description
This quiz addresses the connection between hyperglycaemia and polyuria in diabetes mellitus. It explains how the increase in blood glucose concentration leads to glucosuria and subsequent polyuria. The relationship between insulin deficiency, glucose reabsorption, and urinary excretion is also explored.
