Each group was subdivided into two subgroups: A and B, based on the death of the animals after 30 or 120 days of monitoring. The procedures in groups 2, 3 and 4 were made simultaneously, and splenectomized animals, groups 2 and 3 were donors, respectively, for the animals of groups 3 and 4. In group 4 the spleen was preserved and the animals received implants from the spleens of rats from group 3. The regeneration of splenic tissue was evaluated by macroscopic and microscopic analyzes of the grafts and own spleens, as well as with measurements of VLDL, HDL, LDL, total cholesterol and triglycerides. Results Results ResultsResults Results: after 120 days, Group 4 showed levels of total cholesterol and LDL lower than the other groups. Group 1 had higher levels of lipids. Conclusion Conclusion Conclusion Conclusion Conclusion: The technique of double spleen was effective in the control of lipid metabolism, corroborating the function of the spleen as a reserve of lipids.

Transaminase enzymes and lipid profiles and histological changes in Wistar rats after administration of bintangur (Calophyllum soulattri) leaves ethanolic extract

“…There were also a few theories to explain the role of spleen in the regulation of plasma lipids. Spleen can influence lipid metabolism through the B lymphocytes which were capable of producing antioxidized-LDL antibodies and remove it from the circulation by tissue macrophages (Goncalves et al 2014). There was no effect on the level of total cholesterol, but there was decrease effect on triglycerides profile.…”

“…The level of total cholesterol and triglycerides are indicators used to diagnose damage regulation of lipid metabolism in the liver (Mandal et al 2013). But in some theories, lipid metabolism also can be influenced by spleen condition of hypersplenism and splenomegaly (Goncalves et al 2014).…”

Macro and microscopic comparison of the upper pole of the spleen with the lower pole in partial splenectomy

“…For this reason, partial splenectomy has been performed for an increasing number of indications 1 . In addition to these primordial functions, it was demonstrated in an experimental study that the spleen has a role in the lipid metabolism of rats 2 . This result has not been demonstrated in mice 3 .…”

The role of splenectomy in lipid metabolism and atherosclerosis (AS)

“…This theory seemingly covers both the macrophage activity and the available splenic volume. In states of splenomegaly, overloaded splenic tissue exaggerates the impact of the splenic factor by phagocytosis, with dramatically rising storage volume for lipid, thus lowering serum lipid values [ 43 ], whereas in an asplenic or hyposplenic condition, this very mentioned factor is missed, the splenic parenchyma as well as the macrophage activity undergoes destruction, and the metabolic reactions meet with repercussion, thus improving lipid parameters [ 27 ]. However, this theory is unable to fully interpret the currently existent evidences of lipidic metabolic changes in splenic cells, thus necessitating an in-depth investigation into its innate cellular function.…”

“…By this token, the spleen is not only dedicated to the production of anti-oxLDL antibodies, but also to the clearance of antigen-antibody complexes [ 43 ]. However, unexpectedly, there are also few documentations affirming exacerbation of atherosclerotic lesions with no differences in serum titers of anti-oxLDL antibodies after splenectomy [ 10 , 39 ].…”
