Published on: October 1, 2007
Summary
Topical capsaicin significantly improved random pattern skin flap survival in rats. Topical phenytoin did not show a significant positive effect on flap survival. Further research on phenytoin is warranted.
Area of Science:
- Plastic surgery
- Wound healing research
- Experimental surgery
Background:
- Random pattern skin flaps are crucial in reconstructive surgery.
- Assessing agents that promote skin flap survival is vital.
- Capsaicin and phenytoin are topical agents with potential wound healing properties.
Purpose of the Study:
- To evaluate the efficacy of topical capsaicin and phenytoin in enhancing random pattern dorsal skin flap survival in a rat model.
- To compare the effects of capsaicin and phenytoin against a placebo control.
Main Methods:
- Wistar rats underwent random pattern dorsal skin flap creation.
- Flaps were treated with topical capsaicin (0.1%), phenytoin (1%), or placebo gel.
- Flap necrosis was quantified and compared between groups.
Main Results:
- Capsaicin treatment significantly reduced flap necrosis by 37.27% compared to the control group (p<0.01).
- Phenytoin treatment showed a slight, but not statistically significant, reduction in flap necrosis compared to the control (p>0.05).
- The capsaicin group demonstrated superior skin flap survival.
Conclusions:
- Topical capsaicin effectively increases random pattern skin flap survival in rats.
- Topical phenytoin did not demonstrate a significant benefit for skin flap survival in this study.
- Further investigation into topical phenytoin's efficacy is recommended.

01:44Termination of Translation
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

01:15Variance
The deviations show how spread out the data are about the mean. A positive deviation occurs when the data value exceeds the mean, whereas a negative deviation occurs when the data value is less than the mean. If the deviations are added, the sum is always zero. So one cannot simply add the deviations to get the data spread. By squaring the deviations, the numbers are made positive; thus, their sum will also be positive.The standard deviation measures the spread in the same units as the data.
01:18Finishing Concrete
Concrete finishing starts immediately after the concrete has been placed and consolidated. The initial step, screeding, involves leveling the concrete surface by removing excess material to flush it with the formwork's top. Following this, bull float or darby are employed to smooth the surface further, effectively lower high spots, fill low areas, and ensure larger aggregate particles are embedded within the concrete. This preparation is critical before the appearance of bleed water, as its...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:10Torque
Torque is an important quantity for describing the dynamics of a rotating rigid body. We see the application of torque in many ways in the world, such as when pressing the accelerator in a car, which causes the engine to apply additional torque on the drivetrain. Here, we define torque and provide a framework to create an equation to calculate torque for a rigid body with fixed-axis rotation.
Torque can be considered as the rotational counterpart to force. Since forces change the translational...
