This document discusses different types of pheromones used by social insects including releaser pheromones, sex attractants, alarm substances, trail pheromones, primer pheromones, queen substance, and imprinting pheromones. Releaser pheromones trigger specific behaviors while primer pheromones induce physiological or behavioral changes. Queen substance regulates reproduction and social organization in insect colonies.

This document discusses different types of pheromones in insects, including sex pheromones released by female insects to attract males for reproduction, alarm pheromones that alert others of danger, and aggregation pheromones that promote group behaviors. It also mentions how hormones in humans like insulin, thyroxin, gastrin, and prolactin are released by exocrine glands to regulate metabolic processes, whereas pheromones in insects are released by similar exocrine glands but function for communication between individuals.

Drug use in Peptic Ulcer_A complete review.pptxBaasir Umair Khattak

Open PPT for detail description: Peptic Ulcer Disease (PUD) Peptic ulcer disease refers to mucosal erosions equal to or greater than 5 mm in the stomach or proximal duodenum, caused primarily by an imbalance between gastric acid/pepsin secretion and mucosal defense mechanisms. The most common etiologies include Helicobacter pylori infection, chronic use of NSAIDs, and physiological stress. Classification of Peptic Ulcers 🔹 Based on Location Gastric Ulcers – Occur in the stomach lining. Duodenal Ulcers – Occur in the first part of the small intestine (duodenum). 🔹 Based on Etiology H. pylori–Associated Ulcers NSAID-Induced Ulcers Stress-Related Mucosal Disease (SRMD) Zollinger–Ellison Syndrome (gastrinoma-related) Cushing’s Ulcer (due to intracranial injury) Curling’s Ulcer (seen in burn patients) Pharmacological Management 🔹 1. Acid Suppression Therapy Class Examples Mechanism Proton Pump Inhibitors (PPIs) Omeprazole, Pantoprazole Irreversibly inhibit H+/K+ ATPase pump H2-Receptor Antagonists Ranitidine, Famotidine Block histamine-mediated gastric acid secretion 🔹 2. Mucosal Protective Agents Class Examples Mechanism Prostaglandin Analogues Misoprostol Increases mucus & bicarbonate; decreases acid; protects mucosa Mucosal Coating Agents Sucralfate Forms protective barrier over ulcer site Bismuth Compounds Bismuth subsalicylate Antimicrobial, mucosal protective, and anti-inflammatory 🔹 3. Eradication Therapy (for H. pylori) Combination of: PPI + Two Antibiotics (e.g., amoxicillin + clarithromycin OR metronidazole + tetracycline) Duration: 7–14 days depending on local guidelines See BNF regimens above for detailed protocols 🔹 4. Cytoprotective/Adjunctive Agents Class Examples Role in PUD Somatostatin Analogues Octreotide Used in bleeding ulcers; reduces splanchnic blood flow and gastric secretions Antacids Magnesium hydroxide, Aluminium hydroxide Neutralize gastric acid; provide symptomatic relief Non-Pharmacologic Measures Avoid NSAIDs, smoking, alcohol, and spicy foods Small, frequent meals in symptomatic patients Stress reduction Endoscopic therapy in case of bleeding or perforation Surgical Indications (rarely needed) Perforated ulcer Gastric outlet obstruction Refractory ulcers not responding to medical therapy Severe bleeding unresponsive to endoscopic management ✅ Summary Peptic ulcer disease is primarily driven by H. pylori infection and NSAID use, with duodenal ulcers more common than gastric. Treatment is tailored based on etiology and includes acid suppression, H. pylori eradication, and mucosal protection. Advanced cases may require somatostatin analogues for hemorrhage control or surgery for complications. Prostaglandin analogues like misoprostol are especially valuable in preventing NSAID-induced ulcers.
