Babul (Acacia nilotica)

UV-spectrophotometric and spectroscopic observed Vachellia nilotica and Nigella sativa formulations regularized the histopathological and biochemical parameters during wound contraction

Diabetes mellitus causes impaired diabetic wounds which is linked to a number of pathological alterations that impede the healing of wounds. In the current research, Swiss albino mice were given alloxan monohydrate to induce diabetes and excision wounds of approximately 6 mm using biopsy punch. The diabetic wounds were treated with various biomaterials including Vachellia nilotica extract (VN), Nigella sativa extract (NS), V. nilotica nanoparticles (VNNPs) and N. sativa nanoparticles (NSNPs). Their effects were determined by evaluating the percent wound contraction, healing time, and histopathological analysis. The serum level of various biochemical parameters that is, pro-inflammatory cytokines,  Matrix metalloproteinases (MMPs) and tissue inhibitor matrix metalloproteinases (TIMPs) were also determined. VNNPs group provided the best outcomes, with wound contraction 100% on 12th day. According to histopathological examination, VNNPs group reduced inflammation and encouraged the formation of blood vessels, fibroblasts, and keratinocytes. VNNPs group significantly alleviated the serum level of pro-inflammatory cytokines that are, TNF-α (19.4 ± 1.5 pg/mL), IL-6 (13.8 ± 0.6 pg/mL), and IL-8 (24.8 ± 1.2 pg/mL) as compared with the diabetic mice. The serum level of MMP2 (248.2 ± 7.9 pg/mL), MMP7 (316 ± 5.2 pg/mL), and MMP9 (167.8 ± 12.1 pg/mL) in the same group VNNPs were also observed much less than the diabetic mice. The serum level of TIMPs (176.8 ± 2.9 pg/mL) in the VNNPs group was increased maximally with respect to diabetic mice. It is concluded that nanoparticles and biomaterials possess healing properties and have the ability to repair the chronic/diabetic wound. RESEARCH HIGHLIGHTS: UV-spectrophotometric and Fourier transform infrared spectroscopy observation for functional group analysis and possible linkage between conjugates Optimization of the histopathological and biochemical markers after application of the formulations Microscopic analysis of epithelial tissues for evaluation of healing mechanisms Speedy contraction of wounds as the alleviation of the inflammatory and necrotic factors.

Therapeutic Applications of Plant and Nutraceutical-Based Compounds for the Management of Type 2 Diabetes Mellitus: A Narrative Review

Diabetes mellitus is a condition caused by a deficiency in insulin production or sensitivity that is defined by persistent hyperglycemia as well as disturbances in glucose, lipid, and protein metabolism. Uncurbed diabetes or incessant hyperglycemic condition can lead to severe complications, including renal damage, visual impairment, cardiovascular disease, neuropathy, etc., which promotes diabetes-associated morbidity and mortality rates. The therapeutic management of diabetes includes conventional medications and nutraceuticals as complementary therapies. Nutraceuticals are bioactive compounds derived from food sources that have health-promoting properties and are instrumental in the management and treatment of various maladies. Nutraceuticals are clinically exploited to tackle DM pathogenesis, and the clinical evidence suggests that nutraceuticals can modulate biochemical parameters related to diabetes pathogenesis and comorbidities. Hypoglycemic medicines are designed to mitigate DM in traditional medicinal practice. This review intends to emphasize and comment on the various therapeutic strategies available to manage this chronic condition, conventional drugs, and the potential role of nutraceuticals in managing the complexity of the disease and reducing the risk of complications. In contrast to conventional antihyperglycemic drugs, nutraceutical supplements offer a higher efficacy and lesser adverse effects. To substantiate the efficacy and safety of various functional foods in conjunction with conventional hypoglycemic medicines, additional data from clinical studies are required.

Anticoccidial effects of Khaya senegalensis aqueous stem bark extract on broiler chickens experimentally infected with Eimeria species

Graded concentrations (200, 400 and 800 mg/kg) of the aqueous stem bark extract of Khaya senegalensis was evaluated for its therapeutic efficacy against experimentally induced coccidiosis in broiler chicken. The phytochemical analysis shows the presence of tannins, saponins, cardiac glycosides and steroids. There was significant reduction in oocyst count across the groups in a graded dose manner with 800 mg/kg being the most efficacious dose. There was also weight gain across the treatment groups with immuno-modulatory and erythropoetic activities observed. Also, a significant (p < 0.05) graded dose-dependent reduction in the oocyst count in the treatment groups. A significant (p < 0.05) increase in mean weight gain was also recorded across the experimental groups except the negative control. The haematology also showed a dose-dependent increase in red blood cells, haemoglobin and packed cell volume of the treatment groups. The extract had no significant difference (p > 0.05) on the white blood cells, but a slight decrease in the white blood cells and heterophil counts was observed at 400 mg/kg. Furthermore, the aspartate amino transaminase level showed a significant difference (p < 0.05). Fluctuating levels of other serum biochemical parameters such as total protein, albumin and potassium were observed. No significant difference (p > 0.05) in the sodium concentration was observed. In addition, oxidative stress biomarkers such as catalase significantly increased (p < 0.05) in all the experimental groups in addition to the concomitant increase in reduced gluthathione (GSH) and superoxide dismutase (SOD) levels. Conclusively, the aqueous extract of K. senegalensis was effective in the management of coccidiosis thus supporting its folkloric use.
