The present study aims to prepare a polyherbal formulation (PHF) of Azadirachta indica (Neem), Aloe barbadensis (Aloe vera), Allium sativum (garlic), Acacia arabica (Babul), and Aegle marmelos (Bel) and evaluation of antidiabetic and antioxidant activity utilizing the in vitro model. Air-dried powder of 5 medicinal plants, which are divided into equal portions, and PHF, is prepared by the soxhlet technique using polar and nonpolar solvents. The PHF is screened for the phytochemical screening, and then the antidiabetic activity is determined by alpha-amylase inhibition. The extracts thus obtained are also subjected to the inhibition assay by the use of (DNS) dinitro salicylic acid. The antioxidant activity was determined by the DPPH radical scavenging assay, H2O2 scavenging assay, and TBARS assay. In in vitro study, the result revealed polyherbal formulation in which hot water extract has the topmost inhibitory effect on alpha-amylase activity, ranging from 20.4% to 79.5% with an IC50 value of 48.98 ± 0.31 μg/ml. This extract clearly showed the effective lowering of postprandial hypertriglyceridemia (PPHG). In the antioxidant activity carried out by using the (DPPH) radical scavenging assay, the highest result was obtained by the concentration of 250 μg/ml, which was around 77.2 ± 0.05 with statistical significance compared with control (a: p < 0.01 ; b: p < 0.001 ), while in the GTA method, the highest result was obtained by the concentration of 250 μg/ml, which was around 78.2 ± 0.05, and in the case of the TBARS assay, the concentration of 250 μg/ml gave around 76.2 ± 0.03 anti-oxidant value. In conclusion, the study shows that polyherbal formulation has superior antidiabetic activity and antioxidant properties.

For the treatment and maintenance of postprandial blood glucose increases (i.e., diabetes mellitus), alpha (α)-amylase is a well-known therapeutic target. In this paper, we report an initial exploration of the work, i.e., in vitro alpha-amylase activity of the hydroalcoholic polyherbal extract of the selected plants. After drying, the plant material is ground individually, and at least 100 gm of the crude powder is prepared from each plant. 100 gm of each plant was combined, and a total of 500 gm of the crude powder (Ichnocarpus frutescens (100 gm) + Ficus dalhousie (100 gm) + Crateva magna (100 gm) + Alpinia galangal (100 gm) + Swertia chirata (100 gm)) was prepared to carry out the extraction. This obtained extract was subjected to preliminary phytochemical screening and in vitro alpha-amylase activity. At 16 mg/mL, acarbose displayed 78.40 ± 0.36% inhibition, whereas the extract exhibited 72.96 ± 0.70% inhibition, which is significantly comparable. The IC50 value of acarbose was 12.9 ± 1.12, whereas the extract exhibited 13.31 ± 1.12 mg/mL. The extract possesses numerous classes of chemicals such as alkaloids, glycosides, tannins, polyphenols, and terpenoids, which can contribute to the antidiabetic activity through alpha-amylase inhibition. This was an initial exploration of the work as a proof of concept for the development of polyherbal tea bag formulation for the treatment of diabetes. In the future, we are aiming to investigate the effectiveness of polyherbal tea bags in the treatment of diabetes using more in vitro and in vivo models. From the present investigation, we have concluded that this extract can be used for the treatment of diabetes.

In the present investigation, Ichnocarpus frutescens, Ficus dalhousiae, Crateva magna, Alpinia galanga, and Swertia chirata plants were selected to formulate polyherbal tea bag. The infusion obtained from these polyherbal tea bags was used to formulate 5% and 10% ointment formulation to perform its wound healing activity. The excision wound model was used to assess the wound healing activity in diabetic as well nondiabetic rats. The mean percentage closure of wound area was calculated on the 3rd, 6th, 9th, 12th, 15th, 18th, and finally 21st day. The wound healing activity of formulation was found to be significantly compared with that of the reference standard and untreated groups. The percentages of closure of excision wound area on the 21st day in diabetic animals treated with ointment formulations (F1 and F2) were found to be 93.91 ± 1.65% and 99.12 ± 5.21% respectively, whereas the chloramphenicol sodium drug solution was found to be 99.81 ± 3.16%. The percentages of closure of excision wound area in nondiabetic animals treated with ointment formulations (F1 and F2) were found to be 96.81 ± 2.04% and 98.13 ± 1.14%, respectively, whereas the chloramphenicol sodium drug solution was found to be 99.15 ± 1.41% at 21st day. Therefore, from the above results, we have concluded that this polyherbal ointment can be used clinically for the treatment of diabetic and nondiabetic wounds.

Alzheimer’s disease is an eventually destroying disease of the overaged people featured by the dynamic and gradual brain erosion because of construction of extracellular plaques in the hippocampus. It is an undertreated and underrecognized disease that is becoming a major public health concern. From the study, it is known that production of plaques takes place twenty years back, before the commencement of clinical syndromes. As per report, in 2019, above 50 million people got into Alzheimer’s disease. Recent developments include improved clinical diagnostic guidelines and improved treatment of both cognitive disturbance and behavioral problems. Treatment majorly focus on cholinergic therapy has been clinically evaluated by different studies including randomized, double-blind, placebo-controlled, parallel-group studies measuring performance-based tests of cognitive function, activities of daily living, and behavior. The presence of extracellular plaques of insoluble β-amyloid peptide (Aβ) and neurofibrillary tangles (NFT) containing hyperphosphorylated tau protein (P-tau) in the neuronal cytoplasm is a remarkable pathophysiological cause in patients’ brains. The graph of increasing patients, suffering from Alzheimer’s disease, is being ascended. The outcome of this turn into fatal, deadly situation. So, there is a possibility of breaking down world economics and human strength. There is a different kind of organic as well as inorganic nanocomponent group, those have been pursued with satisfaction. By studying and researching over pathogenesis specifically, diagnosis of this AD as per its symptoms is possibly done. Treatment of this neurodisease is under processing. The experts are playing an extremely appreciable role for displacing this disease completely. The present review summarizes the pathophysiology and role of the nanoparticle in the diagnosis and treatment of AD.

The present study aimed to evaluate the effect of hydroalcoholic extract of Sechium edule (S.E.) fruits on lipid profile and electrocardiogram (ECG) parameters in high fat-diet (HFD) induced hyperlipidemic mice. In this study, grouping of animals was done as described below (n = 6), where group 1 is normal control, group 2 is HFD control, group 3 is HFD + atorvastatin (10 mg/kg), group 4 is HFD + S.E. extract (200 mg/kg), and group 5 is HFD + S.E. extract (400 mg/kg). The first 3 weeks animals were supplemented with HFD, and the last 3 weeks animals were supplemented with HFD along with atorvastatin (10 mg/kg) or S.E. extract (200 and 400 mg/kg). It was observed that mice of the HFD control group showed a significant rise in the total cholesterol, triglycerides, LDL-C, and VLDL-C levels and a notable decrease in HDL-C levels. In addition, a consequential increment in ECG parameters such as QT or QTc and RR interval and a noteworthy decline in the heart rate were observed in HFD control mice. Treatment with S.E. extract (200 and 400 mg/kg) showed a significant improvement in the lipid profile. Moreover, the extract also significantly normalized the prolonged QT or QTc and RR interval and the heart rate in HFD-challenged mice. Hence, we can conclude that S.E. extract encumbers the prolongation of QT or QTc and RR interval and increased the heart rate in HFD-challenged mice.

The current study was devised to develop alternative, nonantibiotic, and economically viable treatments for bovine mastitis. The concentration of 6.25 μg/mL (25 nm) CuNPs was selected as intramammary (IM) treatment in S. aureus-induced mastitis in rats as this concentration showed a significant zone of inhibition through the in vitro sensitivity test and minimal cell toxicity on fibroblast cell lines. After, this in vivo study was conducted, and rats were divided into four groups of 6 rats each: group I (healthy control/deionized water), group II (disease control), group III (CuNPs), and group IV (gentamicin). Injection of gentamicin IM for 5 days was selected on the basis of an antibiotic sensitivity test. The therapeutic efficacy of CuNPs was assessed on the basis of clinical signs, mammary gland architecture, bacterial load, oxidative stress parameters, and histopathology of mammary glands. The clinical signs of mastitis in group III ameliorated within 3 days of treatment while in group IV clinical signs ameliorated within 4 days of initiation of treatment. On the 5th day after randomization, bacterial load, mammary gland weights, TOS (Total Oxidant Status), and OSI (oxidative stress index) were significantly lower in the CuNPs group compared to the disease control group and commercial antibiotic group. Similarly, TAS of group III was significantly higher compared to that of groups II and IV indicating that CuNPs have better ameliorative efficacy in mastitis. Treatment with IM, CuNPs @ 6.25 μg/mL showed early recovery, reduced bacterial loads, and amelioration of oxidative stress indices henceforth resulting in marked amelioration in histopathological changes compared to rats in group IV. From this study, it may be concluded that CuNPs may provide a potential alternative therapeutic regimen for the treatment of bovine mastitis.

Lactobacillus (LAB) genera are considered important functional food but are found to have a short shelf life. In this study, two LAB, Lactobacillus plantarum (Lp) and Lactobacillus rhamnosus (Lr), were isolated from sheep’s milk, and whole-genome sequencing was carried out by using 16s rRNA Illumina Nextseq, the Netherlands. The LAB were encapsulated by the lyophilisation technique using different lyoprotective pharmaceutical excipients. This process was carried out using a freeze dryer (U-TECH, Star Scientific Instruments, India). Shelf-life determination was carried out by a 12-month study using the viability survival factor (Vsf). The in vitro cell adhesion technique was carried out by using the red snapper fish along with autoaggregation and cell surface hydrophobicity as vital probiotic properties. It was observed that Lp has a significantly higher (P < 0.001) Vsf of 7.2, while Lr has a Vsf of 7 (P < 0.05) when both are encapsulated with 10% maltodextrin + 5% sucrose kept at 4°C for 12 months. The result demonstrated that Lp had significantly high (P < 0.05) cell adhesion, 96% ± 1.2 autoaggregation, and 6% cell surface hydrophobicity as compared to Lr. Moreover, this study demonstrated that lyophilised LAB with lyoprotective excipients enhances shelf life without any changes in probiotic properties when kept at 4°C exhibiting all its probiotic properties.
