The rat, due to its size, availability, and rather docile behavior, has been utilized as a research model for many years. The goal of this protocol is to utilize the rat as an ischemic skin wound healing model to provide valuable insight into the pathophysiology of chronic wounds.

Abdominal Exam IV: Acute Abdominal Pain Assessment
0 Views •
2023
Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...

Abdominal Exam II: Percussion

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Medical percussion is based on the difference in pitch between the sounds elicited by tapping on the body wall. The auditory response to tapping depends on the ease with which the body wall vibrates, and is influenced by underlying organs, strength of the stroke, and the state of the body wall. There are three main medical percussion sounds: resonance (heard over lungs), tympany (heard over...

This article provides a detailed and visual description of a methodology for collecting and measuring biochemical inflammatory and nociceptive mediators at the surgical wound site following cesarean delivery. This human bioassay has been used to determine correlations between wound and serum cytokine concentrations and drug-mediated changes in wound cytokines, chemokines and neuropetides.

Repair proceeds through linked responses rather than isolated events. Hemostasis first helps limit damage, while inflammatory signaling organizes the injury environment. Epithelial cells then migrate across the wound, proliferate to replace missing cells, and participate in later remodeling. Studying the sequence helps distinguish early stabilization from processes that restore tissue structure and function.
Developmental stage affects how repair programs interact with tissue growth, differentiation, and regeneration. A wound may therefore activate similar broad responses while producing different recovery outcomes as tissues mature. Comparing stages allows researchers to identify which mechanisms remain conserved and which change with developmental state, providing clues to age-dependent differences in successful tissue restoration.
Hemostasis and inflammatory signaling establish the conditions for subsequent healing. Hemostasis responds to disrupted tissue integrity, whereas inflammatory signals help organize the local response to injury. Their timing and coordination influence when epithelial migration, proliferation, and remodeling can proceed. Examining these relationships can reveal factors that support orderly closure instead of incomplete restoration.
Investigators can examine either controlled injuries or naturally occurring damage, depending on the research question. They follow changes in wound closure, tissue restoration, and the associated repair responses, then relate those findings to developmental growth or differentiation. Comparing conditions or developmental stages helps separate general injury responses from mechanisms specifically linked to regeneration.
These studies can reveal how efficiently tissues close, whether tissue function is restored, and how repair progresses through migration, proliferation, and remodeling. They can also identify factors associated with successful healing or incomplete recovery. Such outcomes provide a framework for connecting visible tissue changes with the cellular and molecular programs activated after injury.
The model links injury responses with processes that normally shape developing tissues. Researchers can ask how repair programs coexist with tissue growth, cell differentiation, and regenerative capacity, rather than examining wound healing in isolation. Cross-stage comparisons may expose conserved cellular and molecular mechanisms and clarify why developing tissues recover differently as their biological state changes.
