The Inhibitory Effect of Pomegranate Peel and Mint Ethanolic Extracts and the Synergy Between Their Active Components on Escherichia Coli and Pseudomonas Aeruginosa Bacteria Isolated from Urinary Tract Infection

Many people rely on medicinal plants to treat illnesses, enhance health, and support a variety of sectors like food and pharmaceuticals. As a result, they are an ancient source of therapy and healthcare. This is as a result of their potent chemicals. This study examined the inhibitory impact of various doses of pomegranate and mint plant alcoholic extracts against Pseudomonas aeruginosa and Escherichia coli, two types of bacterial pathogens that cause urinary tract infections. The studied extracts elicited different responses from the bacteria. The bacteria that responded to the pomegranate peel alcoholic extract the most was Pseudomonas aeruginosa, then Escherichia coli. Pseudomonas aeruginosa was significantly impacted by the pomegranate peel extract, but less so by the mint extract. However, Pseudomonas aeruginosa growth was less affected by the alcoholic extract of mint than Escherichia coli. The combined inhibitory impact of both extracts, at varying doses, was shown to be more effective against Escherichia coli than it was against Pseudomonas aeruginosa.

Efficient removal of paracetamol, diclofenac sodium, and tetracycline using green synthesized Fe-zn co-doped sunflower seed shells

ABSTRACT In this study, carbon material obtained from sunflower seed shells and doped with Fe and Zn using mint extract (Fe-Zn-SSSC) was prepared, and the usability of this adsorbent in the removal of paracetamol, diclofenac sodium, and tetracycline was investigated. Fe-Zn-SSSC was characterized by SEM-EDX and FTIR. Additionally, the effects of pH and adsorbent dosage on the removal of paracetamol, diclofenac sodium, and tetracycline were investigated. The removal rates of paracetamol, diclofenac sodium, and tetracycline were obtained as 88.7%, 65.4%, and 76.0% at a pH of 4, after 1 hour of adsorption with 5 g/L Fe-Zn-SSSC, respectively. The best removal of paracetamol, diclofenac sodium, and tetracycline was obtained at pH 4, with qmax values calculated as 14.51 mg/g, 6.33 mg/g, and 8.99 mg/g, respectively. It was determined that the adsorption of paracetamol, diclofenac sodium, and tetracycline with Fe-Zn-SSSC was more compatible with the Langmuir isotherm model and pseudo-second-order kinetic model. As a result, this study demonstrates that carbon materials synthesized from sunflower seed shells can serve as an effective and low-cost adsorbent for drug from water.

Ultrasonic-aided preparation of poly(vanillin-co-thiophene)/green Fe₃O₄ nanocomposites via solution mixing for methyl orange adsorption and antibacterial applications

This work describes the preparation of novel nanocomposite materials comprising a newly synthesized semiconducting copolymer, poly(vanillin-co-thiophene) (PVTH), blended with different weight proportions (3 %, 6 %, and 9 % by weight) of greenly synthesized magnetite nanoparticles (GFe3O4 MNPs) via solution mixing, assisted by ultrasonic irradiation. PVTH copolymer was synthesized through the polycondensation of vanillin, a bioderived aldehyde, and thiophene, catalyzed by sulfuric acid. GFe3O4 MNPs were prepared via the coprecipitation method with mint extract as an environmentally friendly stabilizer. The physicochemical properties of the prepared samples were investigated by 1H NMR, 13C NMR, FTIR, XRD, UV–vis, TGA, FE-SEM/Eds, AFM, VSM, tauc plot method and the four-points probe measurement. The samples were evaluated for two applications: methyl orange (MO) adsorption from aqueous solutions and antibacterial activities against Gram-negative (Escherichia coli and Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus and Bacillus) bacterial strains. The results showed that ultrasound irradiation facilitated the easy preparation of well-dispersed and homogeneous nanocomposites with combined semiconducting and magnetic properties and improved thermal stability compared to the parent PVTH. The most effective nanocomposite for MO removal was the sample containing 9 % GFe3O4 MNPs, whose adsorption behavior followed pseudo-second-order kinetics and Freundlich isotherm. Its maximum adsorption capacity was 103.79 mg g−1. In addition, all samples showed antibacterial action against the tested bacterial strains, with PVTH showing the highest efficacy, followed by PVTH/GFe3O4 nanocomposites.

Study of the qualitative and sensory properties of yogurt manufactured by adding medicinal and aromatic plant ex-tract(mint)

This research aimed to study yogurt, to which an aqueous extract of the medicinal and aromatic plant (mint) was added to manufacture a new dairy product to improve and treat many different digestive system problems. They were using the lactic acid bacteria (Streptococcus thermophilus and Lactobacillus bulgaricus). The yogurt product was manufactured by adding an aqueous extract of mint with three concentrations of (1%), (2.5%), and (4%) (v/v) mint, and they were represented by N1, N2, and N3 treatments, respectively, as well as the control (C) treatment in which the yogurt was prepared without any addition. The treatments were stored for 21 days at (5±1)°C. The physicochemical and rheological properties were studied, which included measurement (pH, total acidity, viscosity, syneresis, and hardness), microbiological tests, as well as sensory evaluation on the first day of manufacture and after 7, 14, and 21 days of cold storage. The results showed no significant differences in the values of pH and total acidity, While significant differences were found in the values of syneresis, viscosity, and hardness. It was also observed that the numbers of starter bacteria varied for all treatments immediately after manufacturing, but during storage, a gradual decrease in their numbers was observed for all treatments, and the N3 treatment recorded the highest numbers of starter bacteria compared to the other treatments. Also, the results showed superiority of N2 and N3 treatments in the sensory evaluation of flavor, taste, texture and general acceptance.

Cellular absorption and cytotoxic mitigation of heavy metals in mining vegetables in southwest China: Mechanistic insights and health implications

The existing health risk assessment models often rely on total concentrations of contaminants, neglecting cellular absorption, leading to an overestimation of risks due to a lack of toxicological verification. In this study, the content, bioaccessibility, and health risk evaluation of Cr, Ni, Cu, and As in vegetables from mining areas in Southwest China were examined. The cytotoxicity and gastric absorption of heavy metals and underlying mechanisms as well as the toxic mitigation approach after consumption of risky vegetables were explored. Our results showed that the heavy metals in cabbage, celery, and garlic seedlings were within the safety limit, even though grown in contaminated soils. The bioaccessibility of As, Cu, Ni, and Cr in vegetables in the gastric phase is from 6.92% to 81.15%, with mint having the highest bioaccessible concentrations of Cr (32.7 μg/kg), Cu (540.1 μg/kg), and As (103.9 μg/kg). The Hazard Quotient and Hazard Index values of the bioaccessible metals suggested an unacceptable cancer risk. Besides, the vegetable extracts increased cell apoptosis and tight junction disruption. Unexpectedly, the high-risk mint extract with the greatest bioaccessibility didn't cause cytotoxicity but inhibited cell apoptosis and enhanced cellular tight junction, evidenced by the upregulation of Zonula Occludens-1, Occludin, and Claudin 3, and a decrease in cellular heavy metal uptake. Furthermore, the mint extract could alleviate garlic seedling extract-induced cytotoxicity, indicating that the special substance in mint has protective effects. Taken together, special components in vegetables, cellular uptake, and toxicity of heavy metals should be considered in the accurate assessment of health risks.

Insecticidal activity of essential oils and plant extracts on cowpea aphid

Aphid population’s reduction occurs through chemical management, but the indiscriminate use of these products can cause environmental impacts and health risks. This study aimed to determine the insecticidal effects of essential oils and plant extracts as an alternative for aphid control management. The experimental design was entirely randomised in a 5x5 factorial scheme with five replications. Essential oils of rosemary, citronella, corn mint, and hydroethanolic extracts of garlic and cinnamon at five concentrations (0, 10, 20, 40, 80 μL.L−1) were used. In the exposure period of 96 h, the cinnamon hydroethanolic extract and the essential oil of corn mint (Mentha arvensis) showed a greater effect on aphid mortality. The other products evaluated showed lower mortalities but with the potential to be effective with dosages above 80 μL.L−1.

Does acute melatonin supplementation affect cerebrovascular reactivity in healthy young adults?

Melatonin receptors have been found in the cerebrovasculature in animal models, and melatonin has been shown to improve systemic vascular control. While there is a correlation between low melatonin production and cardiovascular disease, the effect of acute melatonin supplementation on the cerebrovasculature, and more specifically, cerebrovascular reactivity (CVR), is unknown. PURPOSE: To determine if acute melatonin supplementation alters CVR via CO2 rebreathing in healthy, young adults. Methods: 14 healthy young adults (Age 23.7±4.39, 7 females tested during the first 5 days of their menstrual cycle) participated in a familiarization visit followed by 2 experimental visits separated by ≥48hrs. Participants received a sublingual dose of either a placebo (PLA, mixture of mint extract and filtered water, to mimic taste of melatonin) or 5mg of melatonin (MEL, mint flavor) in a single-blind, randomized, crossover design. After ingestion, participants rested for 30 minutes prior to the experiment to allow for melatonin levels to reach peak concentration in the blood (Bartoli et al., 2013). After which, mean arterial pressure (MAP, mmHg, finger photoplethysmography), middle cerebral artery velocity (MCAv, cm/s, Transcranial Doppler), and end-tidal CO2 concentration (PetCO2, mmHg, Gas Analyzer) were measured continuously for 5 minutes of supine rest while breathing atmospheric air followed by a CO2 rebreathing challenge (CO2=3%, O2=40%, balanced N2) until the participant displayed a PetCO2 increase of ≥10mmHg. Cerebrovascular conductance index was calculated as CVCi = MCAv/MAP (cm/s/mmHg). CVR was calculated in absolute ΔMCAv/ΔPetCO2, ΔCVCi/ΔPetCO2, and percent change from resting values. Results: Data presented as change (Δ) from rest to CO2 rebreathing, as mean ± SD. All values were not different between treatments during rest. No value was significantly different between treatments when comparing Δ from rest to CO2 rebreathing (MCAv PLA Δ13.35±5.1 vs. MEL Δ11.62±6.03, p = 0.31, d = 0.28, MAP PLA Δ1.75±3.91 vs. MEL Δ-0.55±4.49, p = 0.20, d = 0.34, CVCi PLA Δ0.11±0.04 vs. MEL Δ0.11±0.05, p = 0.55, r = 0.16, CVRMCAv PLA Δ2.75±1.30 vs. MEL Δ3.54±2.57, p = 0.92, r = 0.03, %CVRMCAv PLA Δ18.41±7.07 vs. MEL Δ16.12±10.00, p = 0.36, r = 0.24, CVRCVCi PLA Δ0.02±0.03 vs. MEL Δ0.02±0.02, d = 0.28, p = 0.31, %CVRCVCi PLA Δ2.32±2.58 vs. MEL Δ1.52±1.83, d = 0.28, p = 0.31). CONCLUSION: Our results indicate that melatonin does not affect MCAv, CVCi, MAP, or CVR during rest or CO2 rebreathing. Reactivity was variable individually and did not trend in any direction when comparing PLA treatment to MEL treatment. Thus, melatonin supplementation does not improve cerebrovascular function indicating melatonin supplementation may have differential responses between the cerebral and peripheral vasculature in humans.

The Effect of Biotic Stress in Plant Species Induced by ‘Candidatus Phytoplasma solani’—An Artificial Neural Network Approach

Infections with phytoplasma present one of the most significant biotic stresses influencing plant health, growth, and production. The phytoplasma ‘Candidatus Phytoplasma solani’ infects a variety of plant species. This pathogen impacts the physiological and morphological characteristics of plants causing stunting, yellowing, leaf curling, and other symptoms that can lead to significant economic losses. The aim of this study was to determine biochemical changes in peony (Paeonia tenuifolia L.), mint (Mentha × piperita L.), and dill (Anethum graveolens L.) induced by ‘Ca. Phytoplasma solani’ in Serbia as well as to predict the impact of the biotic stress using artificial neural network (ANN) modeling. The phylogenetic position of the Serbian ‘Ca. Phytoplasma solani’ strains originated from the tested hosts using 16S rRNA (peony and carrot strains) and plsC (mint and dill strains) sequences indicated by their genetic homogeneity despite the host of origin. Biochemical parameters significantly differed in asymptomatic and symptomatic plants, except for total anthocyanidins contents in dill and the capacity of peony and mint extracts to neutralize superoxide anions and hydroxyl radicals, respectively. Principal Component Analysis (PCA) showed a correlation between different chemical parameters and revealed a clear separation among the samples. Based on the ANN performance, the optimal number of hidden neurons for the calculation of TS, RG, PAL, LP, NBT, •OH, TP, TT, Tflav, Tpro, Tant, DPPH, and Car was nine (using MLP 8-9-13), as it produced high r2 values (1.000 during the training period) and low SOS values. Developing an effective early warning system for the detection of plant diseases in different plant species is critical for improving crop yield and quality.

Quality of Refrigerated Squid Mantle Cut Treated with Mint Extract Subjected to High-Pressure Processing.

Squid (Loligo vulgaris) is commonly prone to spoilage, leading to a short shelf-life. High-pressure processing (HPP) can play a role in maintaining the quality and freshness of squid. Along with HPP, food preservatives from natural sources such as mint extract (ME), which are effective, safe, available, and cost-effective, are required. The present study aimed to investigate the combined effect of ME and HPP on the quality of refrigerated squid mantle cuts (SMC) over a period of 15 days. The time-kill profiles of ME and planktonic cell inactivation by HPP were assessed. ME (400 mg/L) inhibited bacterial growth, while planktonic cells treated with HPP (400 MPa) exhibited a reduction at 5 min. Physicochemical and microbial qualities of SMC treated with ME (0, 200, 400 mg/L) followed by HPP (0.1, 200, 400 MPa) for 5 min were monitored during refrigerated storage. Samples treated with ME (400 mg/L) and HPP (400 MPa) exhibited lower weight loss, cooking loss, pH changes, volatile base content, microbial counts, and higher textural properties than other samples. Based on next-generation sequencing results, Brochothrix campestris from family Listeriaceae was the predominant spoilage bacteria in treated sample after 12 days of storage. Therefore, ME and HPP combined treatments exhibited effectiveness in extending the shelf-life of refrigerated SMC.

Harnessing the antimicrobial potential of natural starch and mint extract in PVA-based biodegradable films against staphylococcus aureus bacteria

Sustainable packaging solutions are of paramount importance in addressing the environmental challenges posed by conventional non-biodegradable materials. This study addresses this critical need by introducing a novel approach to crafting antimicrobial biodegradable polymer films. Leveraging the benefits of polyvinyl alcohol (PVA) as a base material, combined with corn-starch (CS) and mint extract (ME), these films offer a compelling synergy of eco-friendliness, antimicrobial efficacy, and mechanical strength. The antimicrobial property was imparted by adding mint extract, and boric acid (BA) was added as a cross-linker for better mechanical properties. All process was done by solution casting method followed by mechanical stirring. After 7 days, starch-PVA blend showed 50% weight loss; however, after adding mint extract, the action of microbes was reduced, and a 50% reduction in weight was observed after 12 days. The excellent mechanical properties were achieved by adding 10% aqueous solution of BA as a cross-linker. The confirmation of BA in the blend was done by the Fourier transform infrared spectroscopy (FTIR). Differential scanning calorimetry (DSC) was used to check the thermal properties of the films. Antimicrobial results showed that mint extract was resistant to staphylococcus aureus bacteria. These biodegradable films offer a multifaceted solution, aligning with sustainability objectives, showcasing antimicrobial potential, and demonstrating mechanical robustness. As such, they hold promise for a diverse array of applications, particularly in the realm of environmentally conscious food packaging. In the pursuit of greener alternatives, these films stand as a testament to innovative materials engineering that harmonizes functionality with ecological responsibility.

Evaluation of the Effect of Some Plant Extracts as Antifungal Substances Isolated from Patients with Gingivitis and Endophthalmitis in Hilla City

During this study, 8 isolates of Candida yeast were isolated and diagnosed on CHROMagar, and Candida albicans was the most prevalent species by 75%. The inhibitory activity of plant extracts of adrak, cloves, green tea, and cinnamon was tested by disc diffusion test against C. albicans, C. krusei, and the antibiotics gentian stain, fluconazole, kenazole, nystatin were used for comparison. As well as using oral and dental cleaning products for comparison as well. The study showed that clove extract had a weak inhibitory activity at a high concentration, while extracts of green tea, cinnamon and mint did not show any activity in inhibiting C. albicans and showed that toothpaste had high activity in inhibiting yeast better than the plant extracts that did not show any inhibitory effect despite their use in high concentrations. We conclude from the current study that it is better to use toothpaste instead of herbs to get rid of gingivitis because it plays a major role in inhibiting Candida yeast.

Exploring the potential of chewing gums containing plant extracts (clove, saffron, and clove-mint) as a natural solution for controlling obesity and associated health issues

Background:Obesity is a global health concern resulting from an excessive accumulation of fat in the body, affecting individuals of all ages, including children. Modern lifestyles and the consumption of high-calorie foods have resulted in an increase in obesity prevalence. Cardiovascular disease, diabetes, blood pressure, and certain cancers are all serious health problems that obesity can lead to.Objectives: Medicinal properties in functional foods are gaining popularity in the food industry for controlling or inhibiting diseases. Given the growing concerns about obesity and its associated health risks, the need for natural compounds with controlling or inhibiting properties is paramount. This study aimed to explore natural plant extracts for their functional properties, particularly their ability to control obesity by inhibiting lipase enzyme. To transport these biological compounds, chewing gums containing extracts of cloves (at concentrations of 0.1%, 1%, and 3%), saffron, and mint were developed. Chewing gums containing extracts can become a popular natural remedy for a variety of health problems, including obesity. Using an effective delivery system, this solution is widely available to those looking for natural alternatives to address their health concerns.Methods: The research centered on exploring the properties of natural plant extracts, which included their potential to inhibit enzymes linked to obesity and related diseases, their antioxidant properties to counteract the harmful effects of body fat oxidation, and their antibacterial properties. In addition, the research involved a sensory evaluation of chewing gum that contained these extracts.Results: Clove extract had the highest amounts of total phenolic compounds. Also, clove extract exhibited the highest antioxidant properties and Helicobacter pylori inhibition (88.05% and 25.69% at ratio of 0.7% respectively), which is thought to be associated with its high content of eugenol and other phenolic compounds. Furthermore, the extracts were evaluated for other functional properties, including their ability to inhibit pancreatic lipase, angiotensin converting enzyme (ACE), and microbial activities against Streptococcus faecalis and Candida albicans. Among extracts, saffron extract showed the highest lipase inhibitory properties (40.07, and 36.06% at concentrations of 0.7% and 0.5% respectively). Also, clove and mint showed pancreatic lipase inhibition about 31.50% and 29.24 % at concentration of 0.7 and 0.5% respectively, revealing that all extracts can be a good candidate to be used as effective additives in preventing and controlling obesity. Also, clove, mint, and saffron extracts could inhibit blood pressure enzymes (25.54, 20.70, and 19.61 respectively), which can help maintain healthy blood pressure levels. Furthermore, release kinetics of extracts from chewing gums were obtained, and shown that after 20 min the release of extracts were 73.24, 64.34, and 63.2 for saffron, mint, and clove (1%) respectively.Conclusions: Extracts were found in our research to have a beneficial effect on controlling obesity. These compounds may be effective in preventing obesity, based on their observed inhibition of pancreatic lipase enzyme. However, further research is necessary to fully comprehend the efficacy of these substances for this purpose. The significant antioxidant properties of clove may have a promising impact on reducing free radicals, which can help prevent fat oxidation in the bodies of individuals with obesity. The inhibition of ACE enzyme by extracts could potentially have a positive impact on controlling blood pressure. The extracts showed potent antimicrobial properties that can potentially alleviate mouth and throat issues associated with Streptococcus bacteria. Moreover, extracts demonstrated efficacy in reducing the presence of H. pylori, which is the causative agent of stomach infections. Also, it was shown that chewing gum can be a convenient and easily accessible means of delivering natural compounds and may be a desirable option for individuals seeking natural alternatives for managing their health concerns.Keywords: Chewing gum, Plant extracts, Obesity, Blood pressure, H. pylori infections

Phytochemical Profiling, Antioxidant, and Antifungal Activities of Ethyl Acetate and Chloroformic Extracts from Three Mentha Species

Background Phytopathogenic fungi remain the main infectious agents in plants, causing severe damage to the environment and human health. Thus, to reduce the usage of synthetically derived fungicides and perform agricultural crop production, the search for new control strategies including plant extracts constitutes an eco-friendly and safe alternative. Objectives This study aimed to quantify the phytochemical constituents of the three plant ( Mentha pulegium L., Mentha spicata L., and Mentha longifolia L.) extracts and to screen their phytochemical composition including total phenolic (TPC), flavonoids (TFC) and condensed tannins contents (TCTC), and to evaluate their antioxidant activities. The efficacy of all mint extracts will be investigated against phytopathogenic fungal species. Materials and Methods The three plant extracts were screened to assess their total phenolic, flavonoids, and condensed tannin contents using spectrophotometric assays. The antioxidant activities include 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric ion reducing antioxidant power (FRAP), and β-carotene assays. The antifungal activities were investigated on phytopathogenic species including Botrytis cinerea, Fusarium culmorum, Fusarium oxysporum, Aspergillus niger, Aspergillus flavus, and Trichoderma sp. Results Quantitative analyses of phytochemical constituents of Mentha genus extracts revealed that both ethyl acetate (EtAc) and chloroformic (Chl) extracts are a rich source of phenols, flavonoids, and condensed tannins. Ethyl acetate extract of M. longifolia (EtAc L) displayed the highest content of phenols (69.9 ± 1.35 mg GAE/g DW) and flavonoids (53.26 ± 2.11 mg CE/g DW), while M. pulegium ethyl acetate extract (EtAc P) has the highest condensed tannins content (2.13 ± 0.4 mg CE/g DW). Moreover, the tested extracts exhibited potent antioxidant activities at low concentrations for EtAc L, followed by M. spicata (EtAc S), and EtAc P (IC50 = 35.76 ± 1.32 µg/mL for scavenging DPPH free radicals; EC50 527.96 ± 5.45 µg/mL for FRAP, and IC50 = 106.3 ± 3.75 µg/mL for β-carotene bleaching test). Finally, all tested extracts were able to inhibit the growth of several phytopathogenic micro-organisms on both agar and broth media. Conclusion The Mentha extracts derived from the three mint species (i.e., L, P, and S) could be used for their antifungal activities to provide sustainable crop pest management.

The Effect of Phenolic Extract of Mint (Mentha spicata) in the Fertility of Male Laboratory Mice.

The current study was conducted to investigate the effect of the phenolic extract of the Mentha spicata plant on the fertility of laboratory mice. The phenolic compounds were extracted using the Reflex condenser from the leaves of the Mentha spicata plant, and it was chemically detected. In the current study,)Albino Mice of the musculus Mus type was used at an age ranging between (12-11) months. The group was randomly divided into three groups. The control group was injected with a physiological solution (0.9% NaCl), the second group was injected with the phenolic extract of the Mentha spicata plant at (100 mg/kg) concentration, and the third group was injected by concentration (200 mg/kg) from the phenolic extract of the Mentha spicata. The phenols were dissolved in a physiological solution (0.9% NaCl), and all individuals of these groups were injected through the peritoneal membrane I.P. at a rate of 0.5 ml per animal per day for 30 days. The phenolic extract of Mentha spicata leaves caused a significant decrease (P<0.05) in the level of Testosterone and Luteinizing hormone (ng/ml) in the blood serum of the first and second treatment group when compared with the control group. The study also indicates a significant decrease (P<0.05) in the concentration of Follicle-Stimulating Hormone in the third treatment group compared with its level in the control group. At the same time, there were no significant changes (P<0.05) for the second treatment group compared with the control group. The average concentration of sperms taken from the caudal epididymis did not change significantly (P<0.05) for both treatments compared to the control group. The percentage of motile sperm decreased significantly (P<0.05) as a result of treatment with the phenolic extract of Mentha spicata leaves, and this percentage is directly proportional to the increase in the doses used of the extract. Sperm vitality compared to the control group, as for the percentage leading to abnormal sperms, the results showed a significant increase (P<0.05) in the average percentage of abnormal sperms in the caudal epididymis of the second treatment animals when compared with the rates of the first and control groups, while there was no There were no significant changes (P<0.05) in the rate of the first treatment compared to the control. Histologically, the results indicate that treatment with phenolic extract of Mentha spicata leaves caused simple histological changes, represented by a simple vacuole of the interstitial layer between the tubules, slight congestion and partial detachment of the germ cells from the basement membrane with a thick fibrous capsule surrounding the epididymis tubes and congestion of blood vessels. In contrast, the seminal tubules and seminal lumen remained normal. This compared to the control group, which showed the semi- Bionatura http://dx.doi.org/10.21931/RB/CSS/2023.08.03.48 2 niferous tubules, seminal cavity and germ layers commonly with normal spermatozoa stages.
