Emergency Medicine Lab
Machine-translated · View original
A lab that combines clinical care to save critically ill patients with basic research on topics such as inflammation.

AboutAbout the lab
Aiming higher in lifesaving care
The Emergency Medicine lab serves as the Advanced Emergency and Critical Care Center of Osaka University Hospital, engaging in clinical care, research, and education.
While treating critically ill patients, the lab uses basic research to study how the body responds to various insults and to investigate treatments that control inflammation.
A distinguishing feature is that problems are identified from clinical information and specimens collected during patient care and then linked to basic research aimed at solving them.
On the lab's website, it is introduced under the name "Handai Kyumei."
Key terms
- Insult
- Various stimuli applied to the body, such as illness and injury. The body responds to them with a range of reactions.
- Inflammation
- The body's reaction to an insult. In moderation it is essential for repairing organs, but when excessive it damages them.
- Immune response
- The body's defensive reaction. In critically ill patients it may not occur appropriately, making them prone to infectious complications.

ResearchResearch themes
While treating critically ill patients at the Emergency and Critical Care Center, the lab studies how the body responds to various insults. It aims to clarify the mechanisms by which insults and treatment effects arise, and to create treatments that can control inflammation.
*Illustrative imageVisualizing the Pathophysiology of Insult
The lab studies how the body responds to and overcomes insults. By visualizing which cells express which RNAs and how proteins act, it aims to clarify pathophysiology and lead to the development of new treatments.
*Illustrative imageControlling Inflammation
In many critically ill patients, disordered and excessive inflammation persists and damages organs. At the same time, appropriate immune responses may fail to occur, making patients prone to infectious complications. The lab aims to elucidate the mechanisms that regulate inflammation and to create treatments that can control it.
