RESUMEN

Objective: To investigate factors directly related to cardiometabolic and cardiorespiratory fitness in transgender people. METHODS: The cross-sectional, experimental study was conducted at the Government Girls Comprehensive Higher Secondary School, Multan, Pakistan, from January to February 2023, after approval from the ethics review committee of the Muhammad Institute of Medical and Allied Sciences, Multan, and comprised transgender people aged 17-28 years. Data was collected using the physical activity readiness questionnaire. All the participants were subjected to Tabata sessions for 4 weeks. Standard cardiometabolic and cardiorespiratory fitness values were noted at baseline and post-intervention. Data was analysed using SPSS 23. RESULTS: Of the 44 participants, 26(59%) were trans-men, 18(40.9%) were trans-women, 16(36.3%) were aged 17-19 years, and 10(22.7%) had other transgender individuals in their families. Cardiorespiratory and cardiometabolic parameters showed significant improvement post-intervention compared to baseline values (p<0.05). Conclusion: Tabata exercises were found to be useful in maintaining cardiorespiratory and cardiometabolic parameters as well in increasing the participants' motor performance.

RESUMEN

The current research was undertaken to scrutinize the effect of leaf meal mixture as concentrate mixture in the ration of goats. Leaf meal mixture (LMM) was prepared using equal quantities of ten top-foliages namely Acacia nilotica, Celtis australis, Ficus palmata, Ficus religiosa, Grewia optiva, Melia azadarach, Morus alba, Quercus incana, Salix alba and Zizyphus jujube obtained from district Poonch of Jammu region in western Himalayas. The LMM prepared was substituted for 15% in the concentrate mixture being fed to the goats. The study constituted of two trials. Concentrate mixture offered to the animals was in mash and multi-nutrient block in first and second trial respectively. A total of twelve non-descript, adult male goats were selected for each trial. Goats of 0-14 months age (27.71 ± 2.96 kg live body weight) of for first trial while goats of 12-16 months age (27.02 ± 2.93 kg live weight) for second trial were divided into control and treatment groups as per randomized block design and fed ad-lib wheat straw and concentrate mixture @ (20 g/kgW0.75). No significant variation was observed (p > 0.05) in body weight, feed and DM intake among all groups in both trials. Comparable intake as well as digestibility of various nutrients like DM, OM, CP, EE, CF, NFE, NDF, ADF and TDN were found between the two groups during individual trials. There was a positive nitrogen, calcium and phosphorus balance among all experimental animals in both the trials. Serum enzymes ALT, AST and haemato-biochemical parameters like total protein, albumin, globulin, albumin: globulin and blood urea nitrogen (BUN) showed no significant differences during both trials in all groups, being within normal physiological levels. However, haemoglobin concentration was significantly higher (P < 0.05) in treatment group with respect to the control group in first trial. On the basis of current results, it can be established that leaf meal mixture can successfully be used to replace concentrate mixture up to 15% in the ration of goats without expecting any adverse impacts on their growth and overall health.

RESUMEN

Rumex vesicarius (L.) is a folklore medicinal herb that has been used for centuries to cure cardiovascular diseases. The present work was carefully designed to ascertain the pharmacological basis for R. vesicarius's therapeutic efficacy in cardiovascular diseases, as well as the underlying mechanism. In the ex vivo investigation, the aqueous-methanolic leaf extract of R. vesicarius was shown to have endothelium-dependent vasorelaxant effects in rabbit aorta tissue preparations, and its hypotensive responses were quantified by pressure and force transducers coupled to the Power Lab Data Acquisition System. Furthermore, when rabbits were subjected to adrenaline-induced myocardial infarction, R. vesicarius demonstrated cardioprotective characteristics. In contrast to the intoxicated group, the myocardial infarction model showed lower ALP, CK-MB, CRP, LDH, ALT, troponin, and AST levels (p > 0.005−0.000), as well as edema, necrosis, apoptosis, inflammatory cell enrolment, and necrosis. R. vesicarius exhibited significant antioxidant activity and delayed noradrenaline-induced platelet aggregation. Its cardioprotective, anticoagulant, and vasorelaxant properties in both investigations (in vivo and ex vivo) are mediated through partial endothelium-dependent, NO and calcium channel blockade mediated vasorelaxation. The minimizing of adrenaline, oxidative stress, and tissue damage demonstrate its therapeutic efficacy in cardiovascular diseases.

RESUMEN

The α-glucosidase enzyme, located in the brush border of the small intestine, is responsible for overall glycemic control in the body. It hydrolyses the 1,4-linkage in the carbohydrates to form blood-absorbable monosaccharides that ultimately increase the blood glucose level. α-Glucosidase inhibitors (AGIs) can reduce hydrolytic activity and help to control type 2 diabetes. Aiming to achieve this, a novel series of 1-benzyl-3-((2-substitutedphenyl)amino)-2-oxoethyl)-2-(morpholinomethyl)-1H-benzimidazol-3-ium chloride was synthesized and screened for its α-glucosidase inhibitory potential. Compounds 5d, 5f, 5g, 5h and 5k exhibited better α-glucosidase inhibitions compared to the standard drug (acarbose IC50 = 58.8 ± 0.012 µM) with IC50 values of 15 ± 0.030, 19 ± 0.060, 25 ± 0.106, 21 ± 0.07 and 26 ± 0.035 µM, respectively. Furthermore, the molecular docking studies explored the mechanism of enzyme inhibitions by different 1,2,3-trisubstituted benzimidazolium salts via significant ligand-receptor interactions.

RESUMEN

Alhagi camelorum (AC) is an old plant with a significant therapeutic value throughout Africa, Asia, and Latin America. The overuse of cisplatin (Cis > 50 mg/m2) is associated with observed nephrotoxicity, ototoxicity, gastrotoxicity, myelosuppression, and allergic reactions. Remedial measures are needed for the protection of nephrotoxicity against cisplatin. Thus, we investigated the nephroprotective effects of AC plant extract to prevent cisplatin-induced nephrotoxicity in albino Wistar rats. The presence of polyphenols, phenolic compounds, tannins, and saponins was revealed during phytochemical investigation, and a significantly intense antioxidant activity was recorded. There were no toxicological symptoms in the treated rats, and no anatomical, physiological, or histological abnormalities were found compared to the control rats. The results of correcting cisplatin-induced nephrotoxicity revealed that the extract has a significant ability to treat kidney damage, with most parameters returning to normal after only three weeks of therapy. It is concluded that co-administration of cisplatin with AC extract showed exceptional nephroprotective effects at a dose of 600 mg/kg for Cis-induced nephrotoxicity.

RESUMEN

This study was done to investigate the anti-clotting and thrombolytic potential of ariel part of Jasminum sambac (L.). Healthy male rabbits were divided into five (5) groups with each group containing six (6) animals. Aqueous-methanolic extract of the plant was prepared and given at different doses of 200, 300 and 600mg/kg to three groups in comparison to negative and positive control groups. The aqueous-methanolic extract showed a dose-dependent increase in the activated partial thromboplastin (APTT) and prothrombin time (PT), bleeding time (BT) and clotting time (CT) (p<0.05). Warfarin 2mg/kg was used as the standard. The plant extract also showed significant (p<0.05) clot lysis in comparison with standard urokinase. Moreover, it also prolonged the ADP induced platelet adhesion at doses of 200, 300 and 600µg/mL dependently. HPLC analysis showed rutin, quercetin, salicylic acid and ascorbic acid as vital phytoconstituents in aqueous-methanolic extract. Anticoagulant and thrombolytic effect of Jasminum sambac justified its therapeutic utility in cardiovascular disorders and this may be due to the presence of salicylic acid, rutin and quercetin in the extract.

RESUMEN

α-Glucosidase inhibitors (AGIs) are used as medicines for the treatment of diabetes mellitus. The α-Glucosidase enzyme is present in the small intestine and is responsible for the breakdown of carbohydrates into sugars. The process results in an increase in blood sugar levels. AGIs slow down the digestion of carbohydrates that is helpful in controlling the sugar levels in the blood after meals. Among heterocyclic compounds, benzimidazole moiety is recognized as a potent bioactive scaffold for its wide range of biologically active derivatives. The aim of this study is to explore the α-glucosidase inhibition ability of benzimidazolium salts. In this study, two novel series of benzimidazolium salts, i.e., 1-benzyl-3-{2-(substituted) amino-2-oxoethyl}-1H-benzo[d]imidazol-3-ium bromide 9a-m and 1-benzyl-3-{2-substituted) amino-2-oxoethyl}-2-methyl-1H-benzo[d] imidazol-3-ium bromide 10a-m were screened for their in vitro α-glucosidase inhibitory potential. These compounds were synthesized through a multistep procedure and were characterized by 1H-NMR, 13C-NMR, and EI-MS techniques. Compound 10d was identified as the potent α-glucosidase inhibitor among the series with an IC50 value of 14 ± 0.013 µM, which is 4-fold higher than the standard drug, acarbose. In addition, compounds 10a, 10e, 10h, 10g, 10k, 10l, and 10m also exhibited pronounced potential for α-glucosidase inhibition with IC50 value ranging from 15 ± 0.037 to 32.27 ± 0.050 µM when compared with the reference drug acarbose (IC50 = 58.8 ± 0.12 µM). A molecular docking study was performed to rationalize the binding interactions of potent inhibitors with the active site of the α-glucosidase enzyme.

RESUMEN

Jasminum sambac (L.) is a South Asian folkloric medicinal plant that has traditionally been used to treat cardiovascular problems. The current investigation was meticulously organized to explore the pharmacological foundation for the medicinal uses of J. sambac pertaining to cardiovascular ailments and to investigate the core mechanisms. Mechanistic investigation revealed that crude leaf extract of J. sambac produced ex-vivo vasorelaxant effects in endotheliumintact aorta ring preparation and hypotensive effect was recorded via pressure and force transducers coupled to the Power Lab Data Acquisition System. Moreover; J. sambac showed cardioprotective effects against adrenaline -induced left ventricular hypertrophy in rabbits observed hemodynamic. CK-MB, LDH, troponin, CRP, ALT, AST, ALP levels were shown to be lower in the myocardial infarction model, as were necrosis, oedema, and inflammatory cell recruitment in comparison to control. J. sambac has shown good antioxidant potential as well as prolonged the noradrenaline induced platelet adhesion. The vasorelaxant and cardioprotective effects in both in vivo and ex vivo experiments, which are enabled by activation of muscarinic receptor and/or releasing the nitric oxide and by reducing the adrenaline, induced oxidative stress, justifying its usage in cardiovascular disorders.

RESUMEN

Plumeria rubra (L.) is a traditional folkloric medicinal herb used to treat cardiovascular disorders. The present investigation was methodically planned to investigate the pharmacological foundations for the therapeutic effectiveness of P. rubra in cardiovascular illnesses and its underlying mechanisms. Ex vivo vaso-relaxant effects of crude leaf extract of P. rubra were observed in rabbit aorta ring preparations. Hypotensive effects were measured using pressure and force transducers connected to the Power Lab data acquisition system. Furthermore, P. rubra displayed cardioprotective properties in rabbits when they were exposed to adrenaline-induced myocardial infarction. In comparison to the intoxicated group, the myocardial infarction model showed decreased troponin levels, CK-MB, LDH, ALT, ALP, AST, and CRP, as well as necrosis, apoptosis, oedema, and inflammatory cell enrollment. P. rubra has revealed good antioxidant properties and prolonged the noradrenaline intoxicated platelet adhesion. Its anticoagulant, vasorelaxant, and cardioprotective effects in both in vivo and ex vivo investigations are enabled by blocking L-type calcium channels, lowering adrenaline, induced oxidative stress, and tissue tear, justifying its therapeutic utility in cardiovascular disorders.

RESUMEN

Sudden infant death syndrome (SIDS) remains the leading cause of infant mortality beyond the neonatal period. An increase in body temperature as a result of high environmental temperature, overwrapping of infants, and (or) infection are associated with SIDS. Endotoxins such as lipopolysaccharide (LPS) and heat stress may perturb cardiorespiratory function and thermoregulation. Although LPS-mediated body temperature and cytokine responses are well documented in older animals, the capacity of LPS to induce fever and cytokine response in young rats remains unclear. Therefore, we sought to investigate the acute effects of LPS on body temperature and cytokine concentrations in rat pups. Postnatal day 7 rat pups were divided into 3 groups: Group 1, rats were administered LPS intraperitoneally (200 µg/kg); Group 2, rats received saline at volume equal to that administered in the LPS group; Group 3, rats received no treatment. Pups were placed in custom-made chambers maintained at ambient temperature of 33 °C. Body surface temperature was continuously monitored for 4 h. Thereafter, the rats were euthanized and serum was collected for cytokine analysis. We demonstrate that LPS treatment increased MIP-1α, IL-10, MCP-1, IP-10, fractalkine, and TNF-α with no concurrent rise in body surface temperature. Although neonatal rats produced an array of cytokines in response to LPS, there was no evidence of fever.

RESUMEN

OBJECTIVE: To assess the counter-irritant and anti-inflammatory activity of Rumexvesicarius in dermatological use. METHODS: The animal-based experimental study was conducted at the Royal Institute of Medical Sciences, Multan, Pakistan, in November 2014. Sodium lauryl sulfate, phenol, histamine and sandpaper irritation models were used. Irritation was induced by the clockwise frictional movement of fine sandpaper to the ear of rabbits and then applying sodium lauryl sulfate, histamine and phenol single topical application onto the ear of the rabbit. The counter-irritant effect was determined by calculating the mean decrease in redness and erythema with those of control and standard dexamethasone. RESULTS: There were 20 rabbits in the study with a mean weight of 1.50±0.033 kg. R. vesicarius (100 and 150mg/mL) showed excellent counter-irritant effect when compared with control and standard groups. Both the doses depicted counter-irritant effect with the highest inhibition (94.42%) in sandpaper group, followed by sodium lauryl sulphate (90%), phenol (94.23%) and histamine (88.46%) irritation models respectively. CONCLUSIONS: Methanol leaf extract of R. vesicarius countered the effect of irritation in experimental animals. It showed significant effect in terms of dose and counter-irritancy time.

RESUMEN

OBJECTIVE: To confirm the effect of human urine in the treatment of wounds, burns and irritation. METHODS: The study was conducted at Bahauddin Zakariya University, Multan, in November 2013 and comprised 15 rabbits of either gender. Irritation was induced by clockwise frictional movement of fine sandpaper to the ear of the rabbits. The counter-irritant activity was determined by calculating the mean decrease in redness and erythema. A group of 3 rabbits each was used while experimenting with the main assay every time the concentration of irritants was increased. The ear treated with distilled water was used as a control. Sodium lauryl sulfate irritation model was also applied and the counter-irritant activity was evaluated. One-way analysis of variance followed by Bonferroni test were used for statistical analysis. RESULTS: The mean weight of the 15 rabbits was 1.5+/-SD kg. Urine (50 and 100µl) showed excellent counter-irritant activity when compared with control and standard dexamethasone. Both the doses showed counter-irritant activity, ranging between 76.84% and 95.68% in the sandpaper model, and 68.90% and 93.68% in the sodium lauryl sulfate model. CONCLUSION: Human urine countered the effect of irritation in experimental animals and can be an alternative way of countering irritation.

RESUMEN

OBJECTIVE: To determine the levels of oxidant, antioxidant and serum enzymes in thalassaemic children receiving multiple blood transfusions. METHODS: The case-control study was done from February to August 2012, and comprised thalassaemic children receiving multiple blood transfusions at Allied Hospital, Ali Zeb Foundation, and the Thalassaemia Centre in Hilal-e-Ahmar Hospital, Faisalabad, Pakistan. Healthy subjects were also screened for any related disease condition that could prejudice the results. Blood samples were analysed for the values of total oxidant status, total antioxidant capacity, serum malondialdehyde, catalase, paraoxonase, arylesterase, glutathione peroxidase and ceruloplasmin. RESULTS: There were 180 children in the study; 90(50%) cases and 90(50%) controls. Of the cases, 48(53.3%) were under-weight while the weight of 42(46.7%) was in the normal range. The values of total oxidant status and total antioxidant capacity were significantly (p<0.01) higher in thalassaemic children compared to normal values. Serum malondialdehyde and catalase levels were also considerably elevated (p<0.05), suggesting the increased activity of these enzymes. However, the concentrations of serum paraoxonase, arylesterase, glutathione peroxidase were significantly (p<0.01) lower in cases than the controls, displaying diminished activities during multiple blood transfusions in these patients. CONCLUSIONS: Multiple blood transfusions disconcert the levels of oxidants, antioxidants and serum enzymes of thalassaemic children. Oxidative damage is seen because of the increased iron overload in these patients. Hence, regular evaluation of oxidant and antioxidant status should be monitored in thalassaemic patients during initial few years of life.

RESUMEN

In the present cross sectional study, we aimed to ascertain the relative associations of GST genotypes with GST activity variations and also with the risk to DMT2 predisposition among men and women separately. Clinical samples obtained from 244 DMT2 cases (120 Males and 124 Females) and 228 controls (117 Males and 111 Females) belonging to Asian Indian ethnicity were used to test for glycemic index, lipid profile, GST activity and GST genotypes. The frequencies of single and combinations of GST genotypes were statistically examined for their association with DMT2 risk among both study groups. The GST activity is significantly lowered in DMT2 group compared to controls (p = < 0.001). This reduction is found to be subjective to single and combinations of GST genotypes among diabetic patients. The frequency distribution for single, double and triple combinations of genotypes of GSTT1, GSTM1 and GSTP1 showed the varying degrees of association with DMT2 risk from 0.5 to 5.6-fold among male and female patients (for all associations, p value was <0.05). Interestingly, GST activity was lowered in both male and female patients with single or combinational genotypes of GSTM1 (Null), GSTT1 (Null), and P1 (V/V) (for all associations, p value was = <0.0001). The reduced anti-oxidant capacity among diabetic patients with certain GST genotypes may have some important implications for disease diagnosis and therapy.

RESUMEN

SARS-CoV-2 infections, commonly referred to as COVID-19, remain a critical risk to both human life and global economies. Particularly, COVID-19 patients with weak immunity may suffer from different complications due to the bacterial co-infections/super-infections/secondary infections. Therefore, different variants of alternative antibacterial therapeutic agents are required to inhibit those infection-causing drug-resistant pathogenic bacteria. This study attempted to explore these bacterial pathogens and their inhibitors by using integrated statistical and bioinformatics approaches. By analyzing bacterial 16S rRNA sequence profiles, at first, we detected five bacterial genera and taxa (Bacteroides, Parabacteroides, Prevotella Clostridium, Atopobium, and Peptostreptococcus) based on differentially abundant bacteria between SARS-CoV-2 infection and control samples that are significantly enriched in 23 metabolic pathways. A total of 183 bacterial genes were found in the enriched pathways. Then, the top-ranked 10 bacterial genes (accB, ftsB, glyQ, hldD, lpxC, lptD, mlaA, ppsA, ppc, and tamB) were selected as the pathogenic bacterial key genes (bKGs) by their protein-protein interaction (PPI) network analysis. Then, we detected bKG-guided top-ranked eight drug molecules (Bemcentinib, Ledipasvir, Velpatasvir, Tirilazad, Acetyldigitoxin, Entreatinib, Digitoxin, and Elbasvir) by molecular docking. Finally, the binding stability of the top-ranked three drug molecules (Bemcentinib, Ledipasvir, and Velpatasvir) against three receptors (hldD, mlaA, and lptD) was investigated by computing their binding free energies with molecular dynamic (MD) simulation-based MM-PBSA techniques, respectively, and was found to be stable. Therefore, the findings of this study could be useful resources for developing a proper treatment plan against bacterial co-/super-/secondary-infection in SARS-CoV-2 infections.

RESUMEN

Histone deacetylases (HDACs) are enzymes that remove acetyl groups from ɛ-amino of histone, and their involvement in the development and progression of cancer disorders makes them an interesting therapeutic target. This study seeks to discover new inhibitors that selectively inhibit HDAC enzymes which are linked to deadly disorders like T-cell lymphoma, childhood neuroblastoma, and colon cancer. MOE was used to dock libraries of ZINC database molecules within the catalytic active pocket of target HDACs. The top three hits were submitted to MD simulations ranked on binding affinities and well-occupied interaction mechanisms determined from molecular docking studies. Inside the catalytic active site of HDACs, the two stable inhibitors LIG1 and LIG2 affect the protein flexibility, as evidenced by RMSD, RMSF, Rg, and PCA. MD simulations of HDACs complexes revealed an alteration from extended to bent motional changes within loop regions. The structural deviation following superimposition shows flexibility via a visual inspection of movable loops at different timeframes. According to PCA, the activity of HDACs inhibitors induces structural dynamics that might potentially be utilized to define the nature of protein inhibition. The findings suggest that this study offers solid proof to investigate LIG1 and LIG2 as potential HDAC inhibitors.

RESUMEN

Potentilla nepalensis belongs to the Rosaceae family and has numerous therapeutic applications as potent plant-based medicine. Forty phytoconstituents (PCs) from the root and stem through n-hexane (NR and NS) and methanolic (MR and MS) extracts were identified in earlier studies. However, the PCs affecting human genes and their roles in the body have not previously been disclosed. In this study, we employed network pharmacology, molecular docking, molecular dynamics simulations (MDSs), and MMGBSA methodologies. The SMILES format of PCs from the PubChem was used as input to DIGEP-Pred, with 764 identified as the inducing genes. Their enrichment studies have shown inducing genes' gene ontology descriptions, involved pathways, associated diseases, and drugs. PPI networks constructed in String DB and network topological analyzing parameters performed in Cytoscape v3.10 revealed three therapeutic targets: TP53 from MS-, NR-, and NS-induced genes; HSPCB and Nf-kB1 from MR-induced genes. From 40 PCs, two PCs, 1b (MR) and 2a (MS), showed better binding scores (kcal/mol) with p53 protein of -8.6 and -8.0, and three PCs, 3a, (NR) 4a, and 4c (NS), with HSP protein of -9.6, -8.7, and -8.2. MDS and MMGBSA revealed these complexes are stable without higher deviations with better free energy values. Therapeutic targets identified in this study have a prominent role in numerous cancers. Thus, further investigations such as in vivo and in vitro studies should be carried out to find the molecular functions and interlaying mechanism of the identified therapeutic targets on numerous cancer cell lines in considering the PCs of P. nepalensis.

RESUMEN

The demand for self-powered, flexible, and wearable electronic devices has been increasing in recent years for physiological and biomedical applications in real-time detection due to their higher flexibility and stretchability. This work fabricated a highly sensitive, self-powered wearable microdevice with Poly-Vinylidene Fluoride-Tetra Fluoroethylene (PVDF-TrFE) nano-fibers using an electrospinning technique. The dielectric response of the polymer was improved by incorporating the reduced-graphene-oxide (rGO) multi-walled carbon nano-tubes (MWCNTs) through doping. The dielectric behavior and piezoelectric effect were improved through the stretching and orientation of polymeric chains. The outermost layer was attained by chemical vapor deposition (CVD) of conductive polymer poly (3,4-ethylenedioxythiophene) to enhance the electrical conductivity and sensitivity. The hetero-structured nano-composite comprises PVDF-TrFE doped with rGO-MWCNTs over poly (3,4-ethylenedioxythiophene) (PEDOT), forming continuous self-assembly. The piezoelectric pressure sensor is capable of detecting human physiological vital signs. The pressure sensor exhibits a high-pressure sensitivity of 19.09 kPa-1, over a sensing range of 1.0 Pa to 25 kPa, and excellent cycling stability of 10,000 cycles. The study reveals that the piezoelectric pressure sensor has superior sensing performance and is capable of monitoring human vital signs, including heartbeat and wrist pulse, masticatory movement, voice recognition, and eye blinking signals. The research work demonstrates that the device could potentially eliminate metallic sensors and be used for early disease diagnosis in biomedical and personal healthcare applications.

RESUMEN

BACKGROUND: Industrial workers often have musculoskeletal disorders due to the nature of their work. OBJECTIVE: The goal was to investigate the scientific use of polyherbal gel in relieving pain and stiffness due to musculoskeletal injuries and improving activities of daily living (ADLs) in industrial workers. METHODS: A pragmatic, single-blinded, randomized control study divided 200 musculoskeletal injury patients into four parallel groups (n = 50). Groups 1 and 2 were applied polyherbal gel via phonophoresis with therapeutic ultrasound and superficial massage. Groups 3 and 4 received diclofenac diethyl-ammonium 1% gel by phonophoresis and superficial massage. The Global Pain Relief Scale, Numeric Pain Rating Scale (NPRS), and Western Ontario and McMaster Universities Arthritis Index (WOMAC) were used to measure pain, stiffness, and ADLs. Data was analyzed using one-way analysis of variance (ANOVA) and paired t-test to compare mean±SD of four independent groups before and after gel application. The confidence interval was 95%, with p < 0.05 considered significant. RESULTS: The results revealed that polyherbal gel reduced pain (NPRS, WOMAC and Global pain relief scales) more efficiently (p≤0.000) when applied with phonophoresis as compared to applied with massage and standard diclofenac (p≤0.005), furthermore, polyherbal gel when applied with phonophoresis showed more efficient results. CONCLUSION: Industrial workers with musculoskeletal injuries benefited from the use of polyherbal gel for pain and inflammation relief. The polyherbal gel is natural, cost-effective, and easy to formulate.
