Abstract: VIEW PDF: EFFECTS OF ARTHROSPIRA (SPIRULINA) ON HEMATOPOIESIS IN RATS The objective of our study was to test the hematopoietic effects of an autohtonous strain of Arthrospira (Spirulina) added to the food of white rats. To investigate these effects we compared the reponse of anemiated and healthy rats to Spirulina feeding.The animals were divided into 3 groups which were fed bread and milk for the first week. The control group (C) received Spirulina powder (3% of the food) for two additional weeks. In the other two groups, during the first week, 25% of the blood was extracted 3 times, in days 1, 2 and 4, in order to induce anemia, while in days 3 and 5, small blood samplings were taken to establish the degree of the induced anemia. One of these two groups, denoted An (anemiated) received only bread and milk for the next two weeks, while the other one, denoted An-Sp, was also anemiated but received Spirulina powder. A blood sampling was also performed at the end of the 3rd week. The state of the animals was evaluated by measuring the blood content of 3 parameters: percent reticulocytes, red blood cell (RBC) count and hematocrit value. The percent reticulocytes and RBC count kept relatively constatnt for the C group, while hematocrit slightly increased. In the An group, the number of reticulocytes was highest at the second sampling (after anemia induction) and slightly decreased afterwards, while in the An-Sp group the number of reticulocytes at the second sampling was moderately lower than in the An group (but significantly higher than in the control) and decreased even more at the final sampling. As expected, the RBC count had a different evolution, increasing in a highly significant way in the An-Sp group, while in the An group it only approached the level of the control, a fact which can be explained by the hematostimulating effect of Spirulina in the An-Sp group. Due to the compensating changes between reticulocytes and RBCs, the hematocrit had only slight variations during the experiment. It is concluded that Spirulina had a hematostimulating effect not only in group An-Sp but also in group C. Keywords: antianemic effect, hematocrit, red blood cells, reticulocytes, Spirulina. |
