RESUMO
The encapsulation of fatty acids, including walnut oil, within complexes is a promising strategy to address challenges, for instance, low water solubility and susceptibility to oxidation while incorporating these oils into food products. Additionally, encapsulation can effectively mask undesirable odor and flavor. The current study focuses on the optimization of walnut oil nanoparticles (WON) using complexes fabricated from gum arabic and whey protein by applying a response surface methodology. The impact of three different independent variables were determined, such as surfactant mixture (33-66%), walnut oil (5-25%), and sonication time (60-300 s), under three distinct desired conditions (low, medium, and high) on four different responses, i.e., particle size, polydispersity index (PDI), moisture level, and encapsulation efficiency (EE). The findings of the present study indicate that the point prediction-based WON resulted in significantly low particle size (82.94 nm), PDI (0.19), moisture content (3.49%), and high EE (77.26%). Fourier transform infrared spectroscopy (FTIR) study demonstrated the successful encapsulation of walnut oil and wall material into nanocapsules. Differential scanning calorimetry (DSC) verified the improved thermal stability property of WON after incorporation, and scanning electron microscopy (SEM) indicated that the WON had relatively fragile and smooth surfaces, along with the presence of few porous structures. The recorded experimental data from the existing study showed that the developed formulation of WON was potentially useful as a value-added ingredient for food industries.
RESUMO
The apricot kernel oil press cake (AKOPC) is a high protein natural by-product of oil mechanical expression with potential uses in cosmetics, medicines, and food. The purpose of this research was to improve the protein extraction process from apricot kernel oil press cake by using enzymatic extraction (EEP), aqueous extraction (AEP), and ultrasound extraction (UEP) process. Protein extraction by AEP was facilitated by a low solid-liquid ratio (SLR) (1:15.97) and prolonged reaction durations (3.30 h), resulting in extraction yields of 68%. When compared to the AEP by similar reaction time, increased enzyme utilization (0.90%) in the EEP resulted in greater protein extraction yields (70%) in a shorter reaction time. In addition to AEP and EEP, ultrasound extraction was also used to improve protein extractability. Temperature (50°C), power density (225 W/L), and extraction duration (20 min) were shown to be the best extraction points. Protein yield was found to be 56.47% at ideal UEP conditions. The experimental values for these reactions were found to be equivalent to the predicted values formed by the mathematical models. When supplementary skimmed milk powder (SMP) was substituted with apricot kernel protein (AKP) in the yogurt manufacturing process, the total solids, average titratable acidity, total protein, and fat contents of the yogurt were increased. In contrast, pH and syneresis values decreased as AKP increased in the resulting yogurt, whether fresh or after 7 days of cold storage. Substitution of additional SMP with AKP in yogurt production might be recommended up to 35%.
RESUMO
This study aimed to evaluate anti-diabetic potential of functional camel milk yogurt enriched with Cinnamomum verum and Stevia rebaudiana that not only mask its peculiar flavour rather have an antidiabetic effect as well. Sixty-three pathogen free STZ-induced albino Wistar rats were categorized into 7 groups on the basis of treatments. From each treatment group three animals were dissected periodically at 0, 7 and 21 days of study to determine the effect of all treatments on physicochemical parameters, serum glucose, serum chemistry and haematology. The study revealed that the mean blood glucose level in the untreated control group was within normal range (100-108 mg/dl) while there was noticeable decrease in mean blood glucose level of all the treated groups during three weeks' trial. Decline in blood glucose level (46%) was higher in animal group containing functional camel milk yogurt (T4) at 3rd week of trial as compared to other treatments.
RESUMO
The objective of this study was to investigate the effects of sun-dried white mulberry fruit powder (WMFP) at addition levels of 2%, 4%, and 6% for enhancing nutritional value and improving the quality of yogurt during refrigerated storage. Results showed that the highest (p < .05) antioxidant activity of 54.53 ± 0.15% was observed in 6% WMFP-added yogurt samples. Highest pH of 4.53 ± 0.08 was observed in control. Significantly highest (p < .05) acidity (1.12 ± 0.02%) was recorded in the yogurt with 6% WMFP-added yogurt samples on 28th day. Moreover, the addition of WMFP elevated the total soluble solids up to 20.05 ± 0.02 °Brix and water-holding capacity up to 55.06 ± 0.34% and lessened the syneresis value (22.92 ± 0.25) in 6% yogurt samples. 2% WMFP-added yogurt sample was given the highest sensory score in terms of overall acceptability by the panelists (8.00 ± 0.00). Thus, it was concluded that fruit powder of white mulberry can be used to improve physicochemical and sensory properties of fortified yogurt. WMFP addition to yogurt enhanced its antioxidant potential and physicochemical quality. The study introduces white mulberry-enriched yogurt and suggests the food industries to launch this product in the market.
RESUMO
Researchers have been enthusiastic about developing high-performance electrode materials based on metal chalcogenides for energy storage applications. Herein, we developed cupric ion-containing zinc sulfide (ZnS:Cu) nanoplates by using a solvothermal approach. The as-synthesized ZnS:Cu nanoplates electrode was characterized and analyzed by using XRD, SEM, TEM, EDS, and XPS. The binder-free flexible ZnS:Cu nanoplates exhibited excellent specific capacitance of 545 F g-1 at a current density of 1 A g-1. The CV and GCD measurements revealed that the specific capacitance was mainly attributed to the Faradaic redox mechanism. Further, the binder-free flexible ZnS:Cu nanoplates electrode retained 87.4% along with excellent Coulombic efficiency (99%) after 5000 cycles. The binder-free flexible ZnS:Cu nanoplates exhibited excellent conductivity, specific capacitance, and stability which are beneficial in energy storage systems. These findings will also open new horizons amongst material scientists toward the new direction of electrode development.
RESUMO
In this work, zinc oxide coupled cadmium tungstate (ZnO-CT) was prepared as a nano-photocatalyst through a green synthesis route using lemon leaf extract and characterized based on diverse microscopic and spectroscopic techniques. To explore the applicabilties of the prepared nanocomposite (NC), its photocatalytic activity has been investigated against Congo red (CR) dye under natural solar light irradiation conditions. ZnO- CT nano-photocatalyst showcases 97% photocatalytic degradation of the CR after 90 min of natural solar light irradiation with quantum yield of 1.16 × 10-8 molecules photon-1. The ZnO-CT NC has shown the enhanced photocatalytic degradation performance against CR when compared to its pristine forms (e.g., ZnO (70%) or CT (44%)). According to the free radical trapping and quenching experiments, the photocatalytic activity of ZnO-CT NC appears to be driven efficiently by superoxide and hydroxyl radicals. The photocatalytic degradation kinetics for CR dye was also studied using the pseudo-first-order, diffusional, and Singh models. The high photocatalytic activity of ZnO-CT NC can be accounted for by the presence of electron-withdrawing functional groups like acids (-COOH) and aldehydes (-CHO) on its surface which helped maintain the prolonged recombination of charge carriers and enhanced stability of ZnO-CT (with moderately low leaching rate of cadmium ions (â¼2-5%)).

Chicory can be used as herbal medicine against different ailments and also added to daily diet as vegetable or animal feed. An efficacy trial was conducted to assess the potential of this plant against liver disorders using rodent modeling. The trials comprised two modules i.e., normal diet and chicory-based supplemented diet. Moreover, experimental animals (rats) were divided into six groups with both modules including C0 (control diet), C1 (Chicory root containing diet), C2 (chicory seed containing diet), C3 (chicory stem containing diet) and C4 (chicory leaf containing diet). During 56 days of the trial period, serum lipid profile, liver and renal functioning tests were performed. The highest feed and water intake, as well as weight gain, was noted in control (C0) trailed by C1, C2, C3, C4 and C5group in an experimental trial, respectively. The resultant diet C2 lowered the liver alkaline phosphatase level (ALP) from C0 (240.72±3.35) to 203.52±2.08 (C2), respectively. Similarly, C2 significantly lowered the ALT from 60.28±2.23 (C0) &57.58±0.91 (C2) in rats. Moreover, C2 treatment showed a maximum reduction of AST from 145.13±2.10 (C0) to 134.52±1.24 (C2), respectively. Convincingly, chicory-based diet may be employed as an alternative to medication in the prevention and treatment of hypercholesterolemia and hepatic malfunctioning.

The present work was conceptualized to determine the potential protective effects of curcumin on arsenic-induced kidney damage in male albino rat model. Thirty six male albino rats were selected, weighed about 175±10g and classified into four groups (9 rats in each group) such as C group (control with basal diet), Cur group (curcumin 200mg/kg body weight), AI group (arsenic-induced 5mg/kg body weight) and AI + Cur group (arsenic 5mg/kg+curcumin 200mg/kg body weight), respectively. Arsenic and curcumin were offered through the gavage method once daily with basal diet. The different analyzed parameters showed that arsenic-induced elevation of aspartate amino transferase, alkaline phosphatase, bilirubin urea, alanine aminotransferase and creatinine significantly decreased with curcumin application in AI + Cur group. Similarly, the statistically significant decline of low-density lipoprotein (LDL), cholesterol, triglyceride and increased in high-density lipoprotein (HDL) was observed in rats of AI + Cur group with curcumin treatment as compared to the rats of AI group. The level of different enzymes of the liver as well as kidney was noted depleted on arsenic exposure whereas increased in level was observed with curcumin application in AI + Cur group. Moreover, pathological histology changes were also recorded. The outcomes suggest that curcumin has a potential effect against arsenic-induced toxicity in biological model.

Currently, there is a major problem of water contaminations, especially of dyes, all over the world. A new technique is being developed daily for the treatment of contaminated water. In many ways, a photocatalytic degradation of a dye by a mixed metal oxide photocatalyst is counted as the best technique for water treatment. This paper also addresses the preparation and photocatalytic application of newly developed mixed metal oxide nanocomposite, CuO-ZnO-CdWO4. A novel mixed metal oxide CuO-ZnO-CdWO4 nanocomposite has been synthesized by a green route using Brassica Rapa leaves extract. The application of CuO-ZnO-CdWO4 as a photocatalyst in wastewater treatment has been thoroughly discussed. Several spectroscopic and microscopic techniques were used to characterize the prepared nanocomposite. The photocatalytic activity of CuO-ZnO-CdWO4 nanocomposite with a band gap of 3.13 eV was observed under the artificial visible light and sunlight for the degradation of Congo red dye. The results under sunlight show the 1.45 times greater removal efficiency than under the artificial visible light. Pseudo-first-order, diffusion, and Singh kinetics models were used to describe the kinetics of dye degradation. Pseudo-first-order model was found to be best fitted model for present study. The performance of CuO-ZnO-CdWO4 was estimated by significant parameters such as quantum yield, figure of merit, turnover number, and mean turnover frequency. The value these parameters were calculated as 1.70 × 10-8 molecules photon-1, 1.77 × 10-4, 2.98 × 108 s-1, and 3.31 × 10-4 s-1, respectively. These parameters revealed high potential of CuO-ZnO-CdWO4 for Congo red dye degradation.

Silver nanoparticles (Ag NPs) were synthesized using Cassia siamea flower petal extract (CSFE) as a reducing agent for the first time. In its presence and absence, the correlative effects of the anionic surface-active agent sodium dodecyl sulfate (SDS) were studied with respect to the development and texture of Ag NPs. Under different reagent compositions, the Ag NPs were inferred by localized surface plasmon resonance peaks between 419 and 455 nm. In the absence of SDS, there was a small eminence at 290 and around 350 nm, pointing toward the possibility of irregular polytope Ag NPs, which was confirmed in the transmission electron microscopy images. This elevation vanished beyond the cmc of [SDS], resulting in spherical and oval shaped Ag NPs. The effects of reagent concentrations were studied at 25 °C and around 7 and 9 pH in the absence and presence of SDS, respectively. Also, kinetic studies were performed by UV-visible spectrophotometry. Prodigious effects on shape and size were found under different synthesis conditions in terms of hexagonal, rod-, irregular-, and spherical shaped Ag NPs. Furthermore, the antimycotic activity of the synthesized Ag NPs was established on different Candida strains, and best results were found pertaining Candida tropicalis. The ensuing study impels the control of texture and dispersity for Ag NPs by CSFE and SDS, and the resultant polytope Ag NPs could be a future solution for drug-resistant pathogenic fungi.
RESUMO
In this work, ZnO-CdWO4 nanoparticles have been synthesized by the ecofriendly green method with lemon leaf extract to favorably anchor functional groups on their surface. The prepared ZnO-CdWO4 nanoparticles are used as adsorbent to treat Congo red (CR) dye after characterization through FT-IR, UV-Vis, TEM, SEM-EDX, and HRTEM techniques. The equilibrium partition coefficient and adsorption capacity values for CR by ZnO-CdWO4 are estimated as 21.4 mg g-1 µM-1 and 5 mg g-1, respectively (at an initial dye concentration of 10 mg L-1). The adsorption process is found as exothermic and spontaneous, as determined by the ΔG°, ΔS°, and ΔH° values. The Boyd plot has been used as a confirmatory tool to fit the adsorption kinetics data along with intraparticle diffusion and pseudo-second-order models. Based on this research, ZnO-CdWO4 nanoparticles are validated as an effective adsorbent for CR dye in aqueous solutions.

BACKGROUND: India is all set to begin vaccination against COVID-19. A good number of people are falling prey to anti-vaccination campaigns, and therefore, some amount of vaccine hesitancy must have developed. The primary objective of the study was to find the level of potential COVID-19 vaccine hesitancy in Kashmiri population. MATERIALS AND METHODS: This was a cross-sectional study conducted in the valley of Kashmir. A predesigned questionnaire was shared online. The participation of respondents was voluntary. Exclusions were made on account of residence outside Kashmir valley, duplicate forms, and wrong information. The data were entered into Microsoft Excel 2010 and analyzed using SPSS version 23. RESULTS: A total of 487 respondents were included. About 67% of the participants were in the age group of ≤30 years, 55% female, 54% rural, and 16% had ever been COVID-19 positive. About 14% of the participants were completely hesitant about receiving the COVID-19 vaccine, whereas 40% were unsure if they will accept the vaccination. The main reason for the total nonacceptance of the vaccine was the doubts about the safety of COVID-19 vaccines (67%). Urban people were more likely to be hesitant to the vaccine than rural people (odds ratio [OR] 1.845, confidence interval CI 1.022 to 3.333). Those who were ever COVID-19 positive were 3.3 times more likely to say "no" to COVID-19 vaccination than those who were never positive. CONCLUSION: Strategic steps must be taken to minimize the vaccine hesitancy associated with COVID-19 vaccination. Authorities should direct efforts toward vaccine education, creating awareness among people about the importance of COVID-19 vaccination.
RESUMO
Monoamine oxidase B (MAO-B) is an important enzyme regulating the levels of monoaminergic neurotransmitters. Selective MAO-B inhibitors have been labeled with carbon-11 or fluorine-18 to visualize the localization of MAO-B in vivo by positron emission tomography (PET) and thereby have been useful for studying neurodegenerative diseases. The aim of this study was to develop promising fluorine-18 labeled reversible MAO-B PET radioligands and their biological evaluation in vitro by autoradiography. Radiolabeling was achieved by classical one-step fluorine-18 nucleophilic substitution reaction. The stability and radiochemical yield was analyzed with HPLC. All five fluorine-18 labeled compounds were tested in human whole hemisphere autoradiography experiments. Five compounds (GEH200439, GEH200448, GEH200449, GEH200431A, and GEH200431B) were successfully radiolabeled with fluorine-18, and the incorporation yield of the fluorination reactions varied from 10 to 45% depending on the compound. The radiochemical purity was higher than 99% for all at the end of synthesis. Radioligands were found to be stable, with a radiochemical purity of >99% in a sterile phosphate buffered saline (pH = 7.4) over the duration of the study. The ARG binding density of only 18F-GEH200449 was consistent with known MAO-B expression in the human brain. Radiolabeling of five new fluorine-18 MAO-B reversible inhibitors was successfully accomplished. Compound 18F-GEH200449 binds specifically to MAO-B in vitro postmortem brain and could be a potential candidate for in vivo PET investigation.

BACKGROUND: Omega-3 fatty acids (Ω-3 PUFAs) may help to improve health status in polycystic ovarian syndrome (PCOS) by reducing numerous metabolic disorders (insulin sensitivity, hyperinsulinemia, lipid profile, obesity and inflammation). To evaluate the current objective, 16 weeks (6 weeks of adjustment period followed by 10 weeks of collection period) research trial was planned to check the impact of different sources of Ω-3 PUFAs (synthetic Ω-3, flaxseed and fish oil) on nutrient digestibility, weight gain, productive (lipid profile, glucose and insulin), reproductive profile (progesterone, follicle stimulating hormone (FSH), estrogen, luteinizing hormone (LH) and prolactin) and histological study of ovarian tissues in Wistar female rats. METHODS: Forty-five rats of 130 ± 10 g weight were divided into 5 groups, each having 9 rats: NC (negative control without PCOS), PC (positive control with PCOS), SO (synthetic omega-3 containing ALA, EPA and DHA), FO (flaxseed oil) and F (fish oil) fed at 300 mg/kg/orally/daily of these sources were added in the basal diets while PC and NC received only the basal diet. Food and water were offered ad libitum. PCOS was induced in the rats fed of PC, SO, FO and F diets group by single intramuscular injection of estradiol-valerate (4 mg/rat/IM). Body weight and blood glucose was recorded weekly. At 16th week of trial, blood samples were collected for lipid and hormonal analysis. Ovarian tissues were removed for pathological evaluation. Digestibility was measured by total collection method. RESULTS: Cholesterol, triglycerides and low-density lipoproteins were reduced in SO, FO and F groups when compared with rats of PC group. However, increasing trend of high-density lipoprotein (HDL) was found in same groups. The highest HDL (36.83 ± 0.72 mg/dL) was observed in rats fed F diet. In case of a hormonal profile, testosterone, LH and insulin levels showed a significant reduction after treatments. Blood glucose results showed significantly reducing trend in all the rats fed with Ω-3 PUFAs sources than PC from 5 to 10th week of trial. However, similar trend was noticed in rat's body weight at the end of 6th week. In ovarian morphology, different stages of follicles were observed in groups fed SO, FO and F diets. Nutrient digestibility in PCOS induced rats was remained non-significant. CONCLUSIONS: The three sources of Ω-3 PUFAs had effective role in improving lipid and hormonal profile, reducing blood glucose, weight gain and histopathological damages in PCOS rats. However, fish oil source might be an innovative approach to cure PCOS via reducing the weight and metabolic anomalies due to EPA and DHA.

The study designed to evaluate the role of sesame, fenugreek flax, and nuts seeds as best alternatives for therapeutic agents to improve bone mineral status. Effect of these plant seeds on proximate composition, antioxidant potential, mineral, fatty acid, and amino acid profile of supplements was studied. The sesame, fenugreek, and flaxseeds were incorporated with nuts at level of 35% to develop supplement. Improved contents of protein, fat, and NFE were recorded in range of 25.72-32.23, 18.92-23.15, and 34.25%-39.59%, correspondingly. The antioxidant potential of supplements is high (450.56 mg GAE/ 100g) prepared with fenugreek followed by flaxseeds and sesame seeds. Calcium as fundamental bone mineral found greater (525.15%-790.21%) in seed-based supplement. Enhanced contents of Oleic, linoleic, and linolenic acids ranged 17.32-41.78, 21.72-44.23, and 1.00%-47.12%, respectively. Nutritional enriched supplements may be best alternatives for improving bone health by lowering osteoclast and increasing osteoblast mechanism in bone development.

RESUMO
BACKGROUND: The spices based dietary interventions are in lime light among the scientific community owing to their promising therapeutic perspective. The bioactive components in spices can be used to exert various health promoting functions in human body such as prompting weight loss, inhibit diet-induced obesity, hypercholesterolemia, hyperglycemia, allergies and various other maladies. In current study extraction and in vitro characterization of coriander seed (CS), black cumin seed (BCS) and fenugreek seed (FS) polyphenols was conducted for further development of dietary intervention against lipid and glycemia related abnormalities in experimental Sprague Dowley rats fed with control and different spice powder supplemented diets. METHODS: Purposely, extraction of Coriander (CS), Black cumin (BCS) and Fenugreek seeds (FS) were carried out by using water and aqueous methanol (70:30 v/v). Afterwards, the resultant extracts were thoroughly investigated for their antioxidant potential through different indices like TPC, TFC, FRAP and ß Carotene Bleaching Assay and ABTS. Furthermore, HPLC quantification were also conducted with special reference to thymoquinone, disogenin, chlorogenic acid, caffeic acid and kaempferol alongside in vitro pancreatic lipase inhibitory activity estimation. Bio-evaluation trial was consisting of three modules i.e. study-I (normal diet), study-II (high cholesterol diet) and study-III (high sucrose diet). Furthermore, rats were sub-divided in five groups in each module on the basis of diet provision including T0 (control), T1 (Diet containing CS), T2 (Diet containing BCS), T3 (Diet containing FS) and T4 (Diet containing CSP + BCSP + FSP). At the beginning of trial, some rats were dissected to evaluate the baseline values whilst rest of the rats was killed at the termination (56th day). Feed and drink intakes were quantified on daily bases whereas, body weight was calculated weekly. Cholesterol level, serum low density lipoproteins (LDL), high density lipoproteins (HDL), triglycerides, glucose concentration and insulin level of collected sera was measured by standard procedures. RESULTS: The in vitro characterization showed better extraction of spices antioxidant through aqueous methanol as compared to water. Among the spices, Black cumin seed alone or in combination revealed highest antioxidant activity in T2 (BCS) followed by T4 (CS + BCS), T7 (CS + BCS + FS), T1 (CS), T6 (BCS + FS), T5 (CS + FS) and lowest in T3 (FS). Likewise, the HPLC characterization showed the presence of thymoquinone in BCS, Dosignienin FGS and chlorogenic acid, caffeic acid and kaempferol in the other treatments. Furthermore, all the treatments showed dose dependent inhibition in Pancreatic lipase activity and order of inhibition was BCS > CS + BCS > CS + BCS + FS > CS > BCS + FC > CS + FS > FS. The maximum feed intake, drink intake and weight gain was observed in T0 (control) trailed by T1, T2, T3 and T4 group in experimental study I, II and III, respectively. The resultant diet T4 enhanced the high density lipoprotein from T0 (58.58 ± 2.51) to 61.71 ± 1.62 (T4) in hypercholesterolemia rats whereas in hyperglycaemia rats the HDL was varied from 38.77 ± 1.2 to 40.02 ± 0.99 in T0 and T4, respectively. Similarly, T2 significantly lowered the low density lipoprotein from 62.53 ± 1.22 (T1) & 46.53 ± 0.99 to 54.88 ± 0.52 & 40.94 ± 1.99 (T2) in hypercholesteraemic and diabetic rats. Moreover, T4 treatment showed maximum reduction as 10.01 & 11.53% in respective studies. CONCLUSIONS: The diet prepared from the different combination of spices has been proven effective against Oxidative stress related physiological malfunctioning.

This study investigated the effect of different doses (0, 3, and 7 kGy) of e-beam on the microbiological and physicochemical qualities and the profile of fatty acids of the frozen duck meat (FDM). Electron beam at the dose of 3 kGy showed more than 2 log and 1 log cycles of reduction in the total bacterial (TAB) and coliform counts (TCC), respectively. The results indicated an increase in the TBARS values (1.50 ± 0.02 mg MDA/kg), peroxide value (0.83 ± 0.04 meq peroxide/kg), and total volatile base nitrogen (1.31 ± 0.16 mg/100 ml), but no effect on the sensory parameters. Irradiation lowered the lightness (L*) (31.87 ± 0.98) and redness (a*) (11.04 ± 0.20) values but elevated the metmyoglobin content in FDM. In addition, irradiation had no effect on the benzopyrene content; however, a reduction was observed in the vitamin A (0.239 ± 0.015 µg/g) and vitamin E (1.847 ± 0.075 µg/g) contents of the FDM samples. There were no trans-fatty acids present in the treated (irradiated) as well as the untreated (nonirradiated) meat samples (FDM), whereas the fatty acid content decreased in irradiated samples, in contrast with the nonirradiated control. Electronic nose clearly discriminated between the nonirradiated and irradiated FDM based on principal component analysis. It is concluded that the e-beam successfully improved the microbial quality of FDM with slight changes in physicochemical properties, but without altering its sensory properties.
RESUMO
Stevia rebaudiana Bertoni a non-caloric, safe and natural sweetener has been shown pharmaceutically important in the management of blood disorders. This study was designed to investigate hematology and safety of stevia aqueous extract through animal modeling. For this purpose, fifty albino rats were categorized into 5 groups and all the groups were received aqueous stevia extract at different dosage levels (200, 300, 400 and 500 ppm/kg b. wt) for 8 weeks except control group. Hematological and toxicological analyses were conducted using standard recommended procedures. The results indicated that biochemical parameters (RBC, HB, HCT, MCV, MCH, MCHC, WBC, eosinophils, lymphocytes and neutrophils) of albino rats significantly (P<0.05) increased and PLT, MPV and monocytes levels non-significantly decreased by using aqueous extract of stevia at different levels after eight weeks of study. Furthermore, Stevia aqueous extracts had non-toxic effect on liver functioning tests. However, stevia aqueous extracts were insignificant in their impression regarding organ to body weight ratios. The stevia aqueous extract has positive effect on hematological parameters of albino rats and is toxicologically safe. Therefore it could be used as a natural remedy for the management of hematological disorders without any health hazards.
