In vitro properties of concentrated canine platelets stored in two additive solutions: a comparative study

چکیده
BACKGROUND Platelet transfusion therapy poses many challenges in veterinary clinical practice. Lack of readily available blood donors, short shelf-life, and inability to administer a sufficient number of platelets to meet a dog's transfusion need are the major difficulties encountered. Platelet additive solutions are already in use at American and European human blood banks, showing to be a realistic alternative. This study compares the in vitro platelet function in plasma, Composol, or SSP+ during storage for 13 days. Platelet rich plasma-platelet concentrate with 35% plasma and 65% platelet additive solutions (Composol or SSP+) and a control group (100% plasma) were prepared. Swirling, platelet count, blood gases, metabolic variables, platelet activation markers, and apoptosis markers were analyzed on days 1, 5, 9 and 13. RESULTS Swirling was well preserved and pH was acceptable (> 6.2) during storage for all platelet additive solutions units until day 9. SSP + units showed more stable pH and metabolic variables until day 13. Platelets in plasma showed higher glucose consumption than in Composol or in SSP+. The platelet additive solutions units showed better platelet metabolism maintenance, reduced glucose consumption and lactate production. The apoptotic markers were still low for 9 days in platelet concentrates with platelet additive solutions, suggesting the possibility to extend the shelf life with the use of SSP+ or Composol. CONCLUSIONS Our findings suggest that the uses of Composol and SSP+ in canine platelet concentrates are potential alternatives in veterinary blood banks.

Evaluation of Biochemical Parameters of Platelet Concentrates Stored in Plasma or in A Platelet Additive Solution (Composol)
Abstract Objective Removing plasma from the platelet concentrate (PC) medium could be an effective way to increase the safety of this product. The goal of this study was to compare PC stored in plasma or in an additive solution (Composol) with in vitro testing. Materials and Methods Fifty-four single donor PCs were prepared from Iranian Blood Transfusion Organization (IBTO). Each PC unit wa...
متن کاملPotatoes: Source of Laboratory Reagent for Human Platelets Research
Irish potatoes is rich in carbohydrate, with varied glucose levels. It is also a very good source of apyrase, an enzyme used for platelet storage. The aim of this study was to explore Irish potatoes as an easily available source for apyrase extraction and purification. Apyrase was extracted from 5 Kg of Irish potatoes. Platelets were derived from 5-10 ml of human whole blood and G6PD activity w...
متن کاملCapability of Platelet Factor 4 to Induce Apoptosis in the Cancerous Cell Lines in Vitro
Background and Aims: Platelet factor 4 (PF4) or CXCL4 is a member of CXC chemokine family which is stored in alpha granules of platelets. The main function known for PF4 is angiostasis which may contribute to prevent tumor metastasis. This feature is mediated by CXCR3 on the endothelial cells. Our principal aim was to study the apoptosis induction in three cell lines treated with PF4 and obtain...
متن کاملComparative in vitro evaluation of apheresis platelets stored with 100% plasma versus bicarbonated Ringer's solution with less than 5% plasma.
BACKGROUND The major strategy for reducing the frequency of adverse reactions to platelet (PLT) transfusions is PLT washing with PLT additive solutions (PASs). In Japan, a mixture of medical infusion solutions such as acetate Ringer's solution, sodium bicarbonate, magnesium sulfate, and ACD-A is currently used as a PAS because none of the common types of PASs are officially permitted for clinic...
