Hyperlipidemia is a major risk factor for coronary heart disease. Hyperlipidemia increases the incidence of myocardial ischemia and cardiac events. This study evaluated the potential hypolipidemic and antioxidant action of the aqueous extract from the uneaten pulp of the fruit from Cordia dichotoma ("CDNP extract"). In vivo studies were performed for 10 weeks on dietary hyperlipidemic and healthy Wistar albino rat models that received two dose levels of the CDNP extract (0.50 and 1.00 g/kg body weight). Serum lipid profiles were determined for the experimental animals. Dietary hyperlipidemic rats were characterized by an elevated lipid profile compared to the healthy control, i.e., increased levels of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C), and triglycerides (TG), although the level of high-density lipoprotein (HDL-C) was reduced. Levels of antioxidant enzymes, i.e., glutathione reductase (GR), glutathione peroxidase (GPx), glutathione-S-transferase (GST), superoxide dismutase (SOD), and catalase (CAT), were significantly higher in the dietary hyperlipidemic rats than in the normal healthy ones, while the level of malondialdehyde (MDA) was significantly lower. Force-feeding hyperlipidemic Wistar albino rats with the CDNP extract at two doses decreased TC, LDL-C, VLDL-C, and TG to normal levels. The risk ratio, which was as high as 870 % for the hyperlipidemic rats was decreased by the treatment to levels close to that calculated for the healthy control rats. Levels of high-density lipoprotein cholesterol (HDL-C) were very low in the hyperlipidemic Wistar albino rats but increased significantly when CDNP extract was adminstered, attaining similar HDL-C levels to those of healthy control rats. Treatment with the CDNP extract also improved the levels of antioxidant enzymes (GR, GST, GPx, SOD, and CAT) in hyperlipidemic Wistar albino rats. Thus, the CDNP extract improves the lipid metabolism of healthy and hyperlipidemic Wistar albino rats and can be employed in the management of dietary hyperlipidemia.

Delta-Like Non-Canonical Notch Ligand 1 (DLK1) is one of the key genes involved in the development of muscle, liver, pancreas, and lung cells; adipocytes production; and the improvement of digestion, growth performance, and meat quality. It has been documented that fennel is effective on increasing the DLK1 gene ( DLK1 ) expression in the testis, liver, and muscle tissues, which may consequently have important implications for sheep production. Hence, the aim of the current investigation was to evaluate the fennel seed powder's effect on DLK1 expression in testis, liver, and humeral muscle tissues in growing lambs. For the purpose of this study, 30 male Kermani sheep were fed with three different group of diets (number of animals in each group was 10), including control (without any fennel seed powder), treatment 1 (with 10 g/kg of dry matter (DM) fennel seed powder), and treatment 2 (with 20 g/kg of DM fennel seed powder) during a 3-month period. Thereafter, total RNA was extracted, cDNA was synthesized, and Real-Time PCR was performed. The addition of fennel seed powder (in the treatment 1 and treatment 2 groups) in the growing lambs diets consequently resulted in greater expression of DLK1 in both the liver and humeral muscle tissues compared to the testis tissue (P < 0.05). Furthermore, the increased DLK1 expression was higher in the tissue of humeral muscle (P < 0.05) in comparison to the other two tissues. As well, the concentration of blood testosterone was greater (P < 0.05) for the animals fed with fennel powder compared to growing lambs fed with the control diet. However, the concentrations of blood liver enzymes, including serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT), decreased by the addition of 10 g/kg DM fennel to diets of lambs compared to the control diet (no fennel). Therefore, it can be concluded that using fennel seed powder in the diet of growing lamb by affecting the expression of DLK1, can improve the concentrations of blood testosterone, SGOT, SGPT, and muscle structure (increased mass of muscle and size of muscle fiber).
Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. Its cause is unknown and it remains the most enigmatic of reproductive disorders. The extant written documents of Traditional Persian Medicine (TPM) – with holistic approaches towards human health – contain remedies used for centuries. Before further experimental research on any of these treatments, it is appropriate to study current related scientific evidence on their possible pharmacological actions. This work aims to study PCOS and its treatments in TPM. To collect data from medieval medicinal texts, six of the most famous manuscripts of Persian medicine were studied. Medicinal treatments for a problem similar to PCOS were searched for in these books. The plants were listed and their authentications were confirmed in accordance with botanical books. PubMed and ScienceDirect databases were searched for related mechanisms of action or pharmacological activities of the medicinal plants reported. From numerous articles, the current work tried to cite the latest publications with regard to each reported plant and PCOS-related mechanisms of action. We studied herbal treatments recommended by ancient Persians to treat a condition called Habs-e-tams, which had the same symptoms of PCOS. It could be concluded that ancient physicians not only wanted to treat the irregular menstrual cycle—which is the most obvious symptom of PCOS—but also their treatment options were aimed at ameliorating the related underlying metabolic dysfunctions. The recommended herbs, which have the most scientific proof for their related actions, can be studied further in experimental analyses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
