  • Parietal cell: Targeted by Gastrin, responsible for secreting HCL into the lumen (top).
  • Microbes: Stylized bacteria are shown above the gland, indicating the protective role of acid.
• Three bullet points explain the flow of the mechanism:
  1. Gastrin can travel through the blood to parietal cells (hormonal action).
  2. Binding of gastrin stimulates the parietal cells to secrete HCL into the lumen of the stomach (the effect).
  3. The high volume of HCL in the stomach keeps the stomach at a pH of 1 or 2 for protection from ingested microbes (the purpose of the acid).

‍

Slide 26 - Gastrin Mechanism of Action (Motility)

• Three steps explain the infection process:
  1. Microbes: "Enter your body through contaminated food or water."
  2. Colonization: "They lodge in the mucous layer of your stomach or duodenum."
  3. Damage: "As the bacteria grow they damage the mucus layer allowing stomach acid to reach the stomach or duodenum lining causing ulcers."

‍

Slide 32 - NSAIDs Mechanism (Inhibition of Mucus Production)

This is a detailed biochemical slide illustrating the mechanism by which Nonsteroidal Anti-inflammatory Drugs (NSAIDs) inhibit the production of the protective mucous layer, leading to ulceration.

• The slide uses a two-row process diagram comparing the normal pathway to the NSAID-inhibited pathway:
  • Top Row (Normal Pathway): Arachidonic acid → Cyclooxygenase (brown dots) → Prostaglandins (teal circles) → Mucous layer production (cell with mucus lining). This shows Prostaglandins are necessary for mucus production.
  • Bottom Row (NSAID Effect): Arachidonic acid → Cyclooxygenase (brown dots) is inhibited by NSAIDs (green dots) → Prostaglandins (teal circles are present, but their action is implied to be blocked or production is reduced) → Mucous layer NOT produced (cell lacks mucus lining). This illustrates that NSAIDs interfere with Prostaglandin's protective role, which is key to maintaining the mucous barrier.

‍

Slide 33 - Zollinger-Ellison Syndrome

This slide provides an illustration and explanation of Zollinger-Ellison Syndrome (ZES), focusing on how a Gastrinoma tumor leads to excessive acid production and ulceration.

• An illustration of the pancreas and duodenal wall. Two Gastrinoma tumors (teal circles with red borders) are shown on the pancreas and duodenum, releasing Gastrin (teal arrow).
  • Text (Bottom Left): Defines the condition: "A gastrinoma is a neuroendocrine tumor that is typically located in the duodenal wall or pancreas, and secretes abnormal amounts of gastrin."
• A magnified, stylized image of a Parietal cell cluster (dark red) with an illustration of its effect.
  • Text (Bottom Right): Explains the effect: "Excess gastrin stimulates parietal cells to release excess hydrochloric acid, which allows ulcers to develop." The labels indicate the Parietal cell and the resulting HCL.

  • It shows the exchange of HCO3−​ for Chloride (Cl−), and the subsequent secretion of Cl− and H+ into the Lumen of the Stomach.
• Key Text:
  • Parietal cells are activated by gastrin, acetylcholine, and histamine.

  • HCO3−​ is exchanged for chloride at the apex and the chloride passes through ion channels into the lumen.

‍

Slide 50 - Normal Parietal Cell Action (Secretion Phase)

This slide continues the detailed, magnified diagram of the Parietal Cell, focusing on the final step of Hydrochloric Acid (HCL) secretion into the stomach lumen, highlighting the role of the proton pump (the target of PPIs).

• A large, stylized illustration of a Parietal Cell continuing the process from the previous slide.
  • The diagram shows the key enzyme ATPase (the H+/K+ pump) moving Hydrogen (H+) into the Lumen of Stomach in exchange for Potassium (K+).
  • Chloride (Cl−) is also shown moving into the lumen.
• Key Text:
  • ATPase then powers the exchange of hydrogen and potassium.

  • Activation signals Gastrin (G), Acetylcholine (A), and Histamine (H) are shown in the Interstitial Fluid.

‍

Slide 52 - Histamine Action On Parietal Cell

This slide provides the molecular mechanism for Histamine's role in stimulating acid secretion, which is key to understanding the action of H2​-receptor antagonists (a class of treatment mentioned in the treatment section).

• A diagram of the Parietal Cell showing the internal signaling cascade initiated by Histamine.
• Mechanism Details:
  • When Histamine binds with the H2 receptor on the parietal cell, it activates adenylyl cyclase.
  • This action induces an increase in cyclic AMP (cAMP) in the parietal cell.
  • The secreted cAMP activates protein kinase, which then activates the proton pump (H+/K+ ATPase) or hydrogen potassium ATPase.
  • The diagram shows H+ being secreted out of the cell and K+ coming in, powered by the ATPase.

‍

Slide 53 - Ranitidine Mechanism of Action (H2​-receptor Antagonist)

This slide concludes the molecular explanation by showing how H2​-receptor antagonists, like Ranitidine, prevent acid secretion, acting as an alternative treatment to PPIs (Proton Pump Inhibitors).

• A diagram of the Parietal Cell showing the H2 receptor.
• Mechanism Details:
  • When Ranitidine (represented by 'R' icons) is taken, it inhibits the binding of Histamine (H) to the H2 receptors.
  • As a result of Histamine blockage, the proton pump (ATPase) doesn't get activated, which prevents the final formation of HCL.
  • The illustration shows H+ being ready for secretion via the ATPase pump, but the Ranitidine molecules block the Histamine signaling pathway.

‍

Slide 54 - Antacids for Peptic Ulcers

This slide provides examples of common Antacids, the fourth class of pharmacological treatment for peptic ulcers, completing the treatment section overview.

This slide explains how Antacids work to treat peptic ulcers and manage symptoms, completing the sequence of treatment mechanisms.

• Mechanism Details:
  • Antacids mainly work by causing neutralization of HCL or the stomach acids.
  • They form harmless Salts and water.
  • As a result, they keep stomach acidity above 4 (pH>4), which inhibits the activity of pepsin.
• Visual Elements:
  • A diagram of the stomach shows an Antacid entering the stomach and neutralizing HCL to form H2​O and Salts.
  • A vertical pH scale on the right graphically illustrates raising the pH from the highly acidic range (1-3) up toward 7.

This slide explains the mechanism of the surgical procedure Pyloroplasty, which is used to address blockages associated with ulcers in the pylorus.

• Mechanism Details:
  • If an ulcer is blocking the pyloric opening of the stomach, a pyloroplasty may be performed.
  • It is done by widening the pylorus, which is the opening between the stomach and duodenum.
  • The surgery allows food to pass through more easily.
• A diagram of the stomach shows the Pylorus with ulcer causing a blockage where Food (represented by green circles) is accumulating. A dashed circle indicates the area of widening.
