Pyramidalis is a triangular muscle situated anterior to the lower portion of rectus abdominis within the rectus sheath (Standring 2016). It originates from the pubis and in an apex that is attached to the linea alba about halfway between the pubis and umbilicus (Standring 2016).

Attachment – from the pubic crest/symphysis to the xiphoid and fifth to seventh costal cartilages. The pyramidalis muscle arises from the pubic crest and blends with its counterpart at the linea alba 4 cm above its origin.

Agathisflavone (FAB) (8-[5,7-dihydroxy-2-(4-hydroxyphenyl)-4-oxochromen-6-yl]-5,7-dihydroxy-2-(4-hydroxyphenyl)chromen-4-one) is a yellow colored biflavonoid that can be extracted from the Poincianella pyramidalis or Anacardium occidentale plants. Poincianella pyramidalis is an endemic plant of the Caatinga, selected by animals grazing on native pasture. Anacardium occidentale, known as the cashew nut, has its origin in north-eastern Brazil. Recently, it has been found to be present in several other countries where the nuts and apples are used for nutrition. FAB has been reported for its antioxidant, antimicrobial, and neuroprotective effects.89 It has also been observed that FAB acts against aminochrome cytoxicity by preventing lysosomal dysfunction and cell death in PD.90 It appears that these protective effects in PD also involve epigenetic mechanisms. In the SH-SY5Y cell lineage and BV2 microglia, it has been demonstrated that the anti-inflammatory and neuroprotective action of FAB involves the activity of the SIRT-1 enzyme in NF-Kb signaling pathway, making this bioactive substance another natural candidate for nutrigenomics therapy against PD.16

Histological studies were carried out in spleen, liver, and bone marrow to analyze the impact of cyclophosphamide on these tissues. Previous reports have also demonstrated that the effect of oxidative stress of cyclophosphamide induces injury to liver, kidney, brain, lung, and other tissues [68,69]. In the present investigation, cyclophosphamide caused destruction of splenocytes in spleen tissue and necrosis of hepatocytes in liver tissue due to oxidative damage. The pathological changes on these tissues induced by cyclophosphamide toxicity are correlated with enzyme activities and up regulation of protein synthesis [70]. Moreover, the oxidative damage of cyclophosphamide administration on the tissues is significantly reduced by the myricetin, apigenin, and hesperidin treatments. Previous studies also suggested that propolis extract (100 mg/kg) and Caesalpinia pyramidalis extract (400 mg/kg) reduced the cyclophosphamide-induced tissue damages in rodents [71,72]. The count of nucleated cells in the bone marrow is a direct index of the process of hematopoiesis [73]. A reduction in the number of these cells in the cyclophosphamide group demonstrated the acute injuries in bone marrow and apoptosis of these cells, although this damage was not apparent in rats pretreated with high concentration of myricetin, apigenin, and hesperidin. Administration of cyclophosphamide decreased the number of megakaryocytes in the bone marrow in this study. Similarly, significant decrease in erythroblast, megakaryocyte, lymphocyte, monocyte and neutrophil counts agrees with the reports of several other authors who noted a profound decrease in these bone marrow cells after administration of cyclophosphamide in laboratory animals [73,74]. However, as a result of myricetin, apigenin, and hesperidin pretreatments, megakaryocytes were significantly increased in rats. Consistent with our results, Anjum et al. [36] have found that plants rich in myricetin possess immunostimulant and anti-thrombocytopenic properties. It is thought that pretreatment with these phytochemicals may mitigate thrombocytopenia through the alleviation of the loss of bone marrow cells in cyclophosphamide-induced cytotoxicity.
