Abstract:
Ease of transfusion and high long-term survival rate were obtained when whole blood was administered via the corpus cavernosum of the penis and removed from the orbital sinus of male C57Bl mice. When 2 volumes of blood are replaced approximately 14% of pre-transfusion red cells remain after hematocrit corrections are made. The post-transfusion hematocrit levels dropped 19%, probably the result of leakage, which is difficult to avoid.
Insights
This study shows that transfusing whole blood into the penile corpus cavernosum and removing it from the orbital sinus in mice allows for easy transfusion and high long-term survival rates.
Area of Science:
- * Physiology
- * Transfusion Medicine
- * Animal Models
Background:
- * Efficient blood transfusion methods are crucial for research and clinical applications.
- * Current methods may have limitations in ease of use and long-term efficacy.
Purpose of the Study:
- * To evaluate a novel whole blood transfusion technique in male C57Bl mice.
- * To assess the ease of administration and long-term survival rates associated with this method.
Main Methods:
- * Whole blood was administered via the corpus cavernosum of the penis.
- * Blood was removed from the orbital sinus of male C57Bl mice.
- * Hematocrit levels were monitored post-transfusion.
Main Results:
- * The described method facilitated easy transfusion and resulted in high long-term survival.
- * Approximately 14% of pre-transfusion red blood cells remained after transfusing two volumes, adjusted for hematocrit.
- * A 19% drop in post-transfusion hematocrit was observed, likely due to unavoidable leakage.
Conclusions:
- * Transfusion via the penile corpus cavernosum and orbital sinus removal is an effective method in mice.
- * This technique offers a viable option for whole blood transfusion with good survival outcomes.
- * Minimizing leakage remains a challenge for optimizing hematocrit levels.
