RESUMEN

Foreign body ingestion is one of the most frequently encountered cases in otorhinolaryngology and most of the cases can be managed non-operatively. If left untreated, migration of foreign bodies can occur and presents a significant challenge in patient management. We hereby describe the case of an elderly gentleman who had a preceding history of fish bone ingestion and complained of dysphagia for two days. Clinical examination revealed swelling of the right vallecula with minimal pus discharge. Computed tomography (CT) of the neck confirmed the diagnosis of a migratory foreign body in the neck. He underwent open neck exploration and foreign body removal under intraoperative fluoroscopy guidance. A high index of suspicion of a migratory foreign body is warranted in cases of persistent, unresolved symptoms with the failure of endoscopic evaluation to detect the foreign body. Migratory foreign body of the neck may cause life-threatening complications and requires early surgical intervention.

RESUMEN

Poly-herbal therapies for chronic diseases like diabetes mellitus (DM) have been practiced in south Asia for centuries. One of such therapies comprises of Hordeum vulgare, Elettaria cardamomum and Cicer arietinum that have shown encouraging therapeutic potential in the treatment of diabetes and obesity. Therefore, poly-herbal granules (PHGs) of this formula were developed and investigated for their anti-diabetic and anti-obesity potential in obese-diabetic rats. The developed PHGs were chemical characterized and the virtual molecular docking was performed by Discovery studio visualizer (DSV) software. For in-vivo experiment, obesity in rats was induced with high-fat high-sugar diet. After that, diabetes was induced by alloxan monohydrate 150 mg/kg i.p. injection. The diseased rats were treated with PHGs at 250, 500 and 750 mg/kg/day for four weeks. GC-MS analysis of PHGs demonstrated the presence of 1,3-Benzenedicarboxylic acid bis(2-ethylhexyl) ester and 1,2-Benzenedicarboxylic acid di-isooctyl ester and phenol, 2,4-bis(1,1-dimethylethyl). Molecular docking of these compounds demonstrated higher binding energies with receptor than metformin against α-amylase and α-glucosidase. PHGs exhibited a decline in body weight, HbA1c, hyperlipidemia, hyperglycemia, and insulin resistance in diseased rats. The histopathological examination revealed that PHGs improved the alloxan-induced damage to the pancreas. Furthermore, PHGs increased the SOD, CAT and GSH while and the decreased the level of MDA in the liver, kidney and pancreas of diseased rats. Additionally, the PHGs had significantly downregulated the TNF-α and NF-κB while upregulated the expression of NrF-2. The current study demonstrated that the PHGs exhibited anti-diabetic and anti-obesity potential through amelioration of oxidative stress, NF-κB, TNF-α, and NrF-2 due to the presence of different phytochemicals.

RESUMEN

Diabetes mellitus (DM) is the most prevalent endocrine disorder. Numerous individual herbs possess anti-diabetic activity. The seeds of Hordeum vulgare, Elettaria cardamomum and Cicer arietinum are traditionally used to manage DM. The ambition of this work was to formulate the poly-herbal granules (PHGs) comprising of these three functional foods and evaluate their in-vitro antioxidant and antidiabetic potential. The dried seed extracts of Hordeum vulgare, Elettaria cardamomum and Cicer arietinum were used in a ratio of 2.5:1:1 to formulate PHGs by wet granulation method. The ratio of extracts was selected on the basis of traditional phytotherapies popularly used by local Hakeems of Pakistan to achieve glycemic control in diabetic patients resistant to traditional allopathic regime of medicine. The flow properties of developed PHGs were evaluated. The UV-Visible spectroscopic, Fourier Transform Infrared (FTIR) and HPLC-DAD of all seed extracts and PHGs were performed. The in-vitro antioxidant DPPH, FRAP, total antioxidant capacity (TAC) and Nitric Oxide (NO) scavenging assays were carried out on PHGs. The in-vitro antidiabetic activity of PHGs was investigated by alpha-amylase and alpha-glucosidase enzyme inhibition activity. The developed PHGs exhibited excellent flow properties. The UV-Vis spectra of all seed extracts and PHGs demonstrated peak at 278 nm showing the presence of flavonoids and phenols. The FTIR spectra confirmed the existence of flavonoids, and phenols along with amines in seed extracts as well as PHGs. The HPLC-DAD test revealed the existence of gallic acid, ascorbic acid, Quercetin-3-(caffeoyldiglucoside)-7-glucoside, Rosmarinic acid, delphinidin-3,5-diglucosides, Kaempferol-3-feruloylsophoroside-7-glucoside and Phloroglucinol in PHGs. The PHGs exhibited IC50 of 51.23, 58.57, 55.41 and 53.13 µg/mL in DPPH assay, FRAP assay, TAC, Nitric oxide scavenging assays respectively. The PHGs also demonstrated IC50 of 49.97 and 36.16 µg/mL in alpha-amylase and in alpha-glucosidase inhibition assays respectively in dose dependent manner. The developed PHGs exhibited an excellent flow property. These exhibit significant in-vitro antioxidant and antidiabetic profile by virtue of flavonoid and phenolic acid derivatives.

RESUMEN

Hydroxyapatite (HA) scaffold was made using the powder metallurgy with an use of a space holder method with a pore-forming agent from green phenolic (GP) granules. The novelty of this study was the use of GP granules as an agent that does not melt at high temperatures to avoid damaging the tangential contact between the HA powder during the sintering process. HA from snapper scales was added and mixed with polyvinyl alcohol (PVA) and ethanol to form a slurry. The ethanol content was then removed by drying at room temperature. The HA, which contained PVA, was added with GP granules as a pore-forming agent in various amounts to get the desired porosity. The green body was made using a stainless steel mold with the uniaxial pressing process under a pressure of 100 MPa. To make a scaffold sintered body, a sintering process ran at 1200 °C with a holding time of 2 h while maintaining the heating and cooling rates at 5 °C/min. The physical properties of the scaffold sintered body were characterized through linear shrinkage test, pore measurement, porosity test, phase observation by X-ray diffraction (XRD), and microstructure observation by scanning electron microscopy (SEM) and digital microscopy (DM). So were the mechanical ones through a compressive strength test. The results showed that the sintered body had a compressive strength value of 1.6 MPa at a porosity of 60.7% with a pore size of 129-394 µm. The scaffold contained interconnections between pores at a HA:GP ratio of 55:45 wt%, which matched the condition required for cell tissue growth. The conclusion is that GP granules are good enough to be used as a pore-making agent on scaffolds using the space holder method because they do not damage the tangential contact between the HA powder during the sintering process. However, efforts are needed to remove the remaining GP ash on the scaffold.

RESUMEN

Fenbfen is used for pain, pyrexia and in the management of osteoarthritis, rheumatoid arthritis and other musculoskeletal disorders. The present research was planned to examine the immunomodulatory activity of fenbufen in different models of cell-mediated immunity (CMI) and humoral immunity (HI). The CMI was evaluated by delayed-type hypersensitivity (DTH) and cyclophosphamide-induced neutropenia assays while HI was appraised by hemagglutination (HA) assay by administering fenbufen at 2, 6 and 10 mg.kg-1 and azathioprine 40 mg.kg-1 (as standard therapy) to albino mice by intraperitoneal route. The ex vivo immunomodulatory action was determined by red blood cell (RBC) membrane stabilization and protein denaturation assays. The results showed that fenbufen treatment had significantly (p<0.05-p<0.001) reduced white blood cells, hemoglobin content, and red blood cells in the healthy and neutropenic mice. A significant (p<0.001) reduction in activities of superoxide dismutase and catalase and glutathione contents, and enhancement of malondialdehyde level were observed in neutropenic mice that were restored by fenbufen treatment. It suppressed DTH reaction after 24, 48 and 72 h post topical application of 2, 4-dinitrofluorobenzene (DNFB). Fenbufen or azathioprine treated groups also showed a significant reduction in the antibody titer against human RBCs induced immune activation in mice as compared to the disease control mice. Fenbufen showed IC50 of 14.0, 50.5 and 66.2 µg.ml-1 whereas, diclofenac sodium showed IC50 of 61.0, 126 and 50.5 µg/ml in RBCs membrane stabilization, egg albumin and bovine serum albumin denaturation assays respectively. The current study shows that fenbufen might have potential immunomodulatory activity against CMI and HI. It can be utilized to treat immune system disorders.

RESUMEN

The current work was performed to explore the pharmacological mechanisms involved in the management of asthma and hypertension along with the safety profile of the Ceratonia siliqua (C. siliqua/Carob) pods. The bronchorelaxant, vasorelaxant, and cardioselective activities of C. siliqua pods were investigated using isolated rabbit tracheal, aortic, and paired atrial fragments on the Power lab data acquisition system. Normotensive rats were used to study antihypertensive activity. The plant extract and its fractions relaxed the carbachol-induced contraction in the tracheal fragments and shifted the concentration-response curve of carbachol towards the right confirming the muscarinic receptor antagonist activity. The relaxation of phenylephrine-induced contraction in an aortic fragment by the extract showed α- adrenergic blocking activity. Furthermore, the extract produced a cardio-selective response in the paired atria and decreased the blood pressure in anesthetized normotensive rats. The plant extract proved to be non-toxic in oral acute and chronic toxicity studies and did not demonstrate any sign of histopathological lesions. These results suggested that the plant extract was non-toxic and could be used in the management of lifetime therapies of respiratory and cardiovascular disorders without any unwanted effects.

RESUMEN

INTRODUCTION: Cultural backgrounds can influence the smell test because of the unfamiliarity of different populations with a number of odorants. The study aims to determine the cutoff points for hyposmia using the cultural adaptation of the Malaysian version of the Sniffin' Sticks identification smell test among different age groups. METHODS: In this cross-sectional study, healthy participants were recruited from a hospital, senior citizen homes, and schools from 2019 until 2021. Participants were divided into 5 different age groups (A: children, B: adolescents, C: young adults, D: middle-aged adults, and E: older adults) and underwent the identification smell test. Scores below the 10th percentile in these age groups were used to determine the cutoff points for hyposmia. RESULTS: The cutoff points for the smell identification scores for hyposmia at the 10th percentile in children, adolescents, and adults (young, middle-aged, and older) were less than 6, 9, and 11, respectively. Pairwise comparisons were made using the Bonferroni post hoc test, with p < 0.001. Scores showed a significant difference between males (mean [SD]: 11.43 [2.42]) and females (12.01 [1.98]); p = 0.005. CONCLUSION: Our study found that the cutoff points of the identification smell test for hyposmia were lower than those of other studies. It is important to use these cutoff points in our population to establish the correct integrity of olfaction function in the clinic setting and in future research.

RESUMEN

BACKGROUND & OBJECTIVE: Peganum harmala has been traditionally used to manage rheumatoid arthritis (RA) and other inflammatory conditions. However, its use against RA has not been scientifically evaluated. The current study was designed to assess the anti-arthritic and anti-inflammatory activities of the methanolic extract of P. harmala leaves by in vitro and in vivo methods. METHODS: The in vitro assays were carried out to determine the effect of plant extract on inhibition of egg albumin denaturation and human red blood cell membrane (HRBC) stabilization. Moreover, 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity was performed to determine the antioxidant potential. In vivo anti-arthritic activity was performed by determining the curative effect against Complete Freund's adjuvant (0.1 ml). The plant extract was administered to rats orally at 200, 400 and 600 mg/kg/day for 21 days. RESULTS: The values of IC50 of plant extract in protein denaturation, stabilization of HRBC and DPPH assays were 77.54 mg/ml, 23.90 mg/ml and 58.09 µg/ml, respectively. Moreover, the plant extract significantly attenuated the poly-arthritis and weight loss, anemia and paw edema. The plant extract restored the level of C-reactive protein, rheumatoid factor, alanine transaminase, aspartate transaminase and alkaline phosphatase in poly-arthritic rats. Moreover, the plant extract restored the immune organs' weight in treated rats. Treatment with P. harmala also significantly subdued the oxidative stress by reinstating superoxide dismutase, reduced glutathione, catalase and malondialdehyde in poly-arthritic rats. The plant extract notably restored the prostaglandin-E2 and tumor necrosis factor (TNF)-α in the serum of poly-arthritic rats. CONCLUSION: It was concluded that P. harmala extract had potential antioxidant, anti-inflammatory and antiarthritic activities, which primarily might be attributed to alkaloids, flavonoids and phenols.

RESUMEN

OBJECTIVES: To assess olfactory abilities using a culturally adapted Sniffin' Sticks smell test in different age groups. METHODS: This was a cross-sectional study, conducted at Otorhinolaryngology outpatient clinic of Universiti Kebangsaan Malaysia Medical Centre, Secondary Science School, and Children Learning Centre in Kuala Lumpur, Malaysia, from August 2019 until December 2021. RESULTS: In 450 healthy participants, the cut-off points of the threshold discrimination identification (TDI) scores at the 10th percentile for olfactory abilities were 19 in children, 30.1 in adolescents, 32.1 in young adults, 31.1 in middle-aged adults, and 28.6 in older adults. The children had significantly lower olfactory abilities, with the Bonferroni post-hoc tests of p<0.001. The young adults had higher olfactory abilities than older adults (p<0.05). The results showed that the identification score was highest in middle-aged adults (p<0.001). The discrimination score was the highest in young adults (p<0.001). The best odor threshold performance was observed in adolescents (p<0.001). The TDI score showed a significant difference in olfactory abilities between men and women (p=0.001). CONCLUSION: Using a culturally adapted smell test, our population was able to identify, discriminate, and perceive odorants better than the European population. This data will help clinicians and researchers with a tool to reliably establish the correct results of olfactory function in our population. Women had better olfactory abilities than men.

RESUMEN

The study was carried out to evaluate the hepatoprotective potential of aqueous methanolic extract of Heliotropium strigosum (HSME) against paracetamol induced hepatotoxicity in Swiss albino mice. The plant powder (1.5Kg) was macerated in aqueous methanol (30:70) for 7 days. The extract was evaluated for the presence of different phytochemicals and High-performance liquid chromatography (HPLC) analysis. HSME was orally administered to mice at 125, 250 and 500mg/kg for 8 days followed by paracetamol intoxication (500mg/kg orally) on the 8th day using silymarin as standard control. All the therapy was administered by oral gavage. The liver biochemical parameters and histopathological evaluation were carried out to assess changes in liver function and histology. HPLC analysis confirmed the presence of quercetin, kaempferol, and other phenolic compounds. Treatment with the extract resulted in notable (p<0.05) reduction in liver parameters in dose dependent manner. The action of HSME 500mg/kg dose was comparable to silymarin. The effect of HSME against paracetamol induced hepatotoxicity was demonstrated by protective changes in the liver histopathological which proved the traditional uses of the plant.

RESUMEN

To evaluate the anti-diabetic potential of aqueous methanolic extract of Conyza bonariensis amongst the Wistar rats. Phytochemical and High Performance Liquid Chromatography (HPLC) analyses of phenols and flavonoids were examined. The plant extract (250 and 500mg/kg/day) was explored for its anti-hyperglycemic effect for 14 days in normoglycemic and alloxan-induced diabetic rats using the oral glucose tolerance test (OGTT). HPLC analyses demonstrated the composition of the plant extract as gallic acid, cinnamic acid, quercetin, p-coumaric acid and syringic acid. The blood glucose concentrations in experimental diabetic as well as non-diabetic rats significantly decreased with doses 250 and 500 mg/kg in OGTT. Moreover, the significant drop in fasting glucose level was observed following 14 days of therapy. It also ameliorated the serum cholesterol, total protein, low and high density lipoproteins, glycosylated hemoglobin A1C and serum amylase with respect to untreated rats suffering from diabetes. There appeared to be no significant alteration with regard to body weight amongst the treated rats. The plant extract revamped the pancreatic islets of Langerhans and abridged alloxan-induced degenerative changes in the liver. It can be concluded that Conyza bonariensis extract has a pronounced hypoglycemic effect on diabetes due to the presence of phytochemicals.

RESUMEN

BACKGROUND: Fruit peels are considered as waste and contribute to a major proportion of the biomass. They can be a good source of various therapeutic benefits. Peels biomass of citrus fruits is usually considered as garbage. Such peels may have many important and valuable medicinal components with pharmacological activities. Citrus reticulata, (Rutaceae family, local name tangerine) is a local seasonal fruit in Pakistan, a very good example of wastage of its peels. OBJECTIVE: The study is based on the exploration of a citrus fruit peel derived essential oil, its chemical characterization, identification of various bioactive components and the exploration of pharmacological potentials (antibacterial and wound healing activity). METHODS: Essential oil was recovered by hydro-distillation of freshly collected peels. Chemical constituents of oil were determined by Gas Chromatography-Mass Spectroscopy (GC-MS) analysis. Antioxidant activities were evaluated by total phenolic contents, total flavonoid content, DPPH scavenging activity and reducing power assay. Antibacterial activity was determined using disc diffusion assay. In vivo wound healing potential was determined in rabbits after topical administration of oil. Wound scoring was calculated followed by histological study. RESULTS: GC-MS analysis showed the presence of various components with the greatest proportion of D-Limonene (89.31%). Total flavonoid and phenolic contents were found to be 14.63 ± 0.95 mg CE/g and 17.03 ± 3.24 mg GAE/g respectively, while DPPH activity was found to be 73.32%. A better antibacterial activity was shown against E. coli. In vivo studies showed significant reduction in wound diameter in essential oil treatment groups. Further, the essential oil was found non-irritant in draize scoring. CONCLUSION: The study concluded that essential oil of this fruit peel might be used for antibacterial and wound healing purposes.

RESUMEN

BACKGROUND: Tylophora hirsuta (Wall) has long been used as traditional medicine for the treatment of diabetes. The current study is designed to evaluate the anti-diabetic and anti-inflammatory activity of different extracts of aerial parts of Tylophora hirsuta. METHODS: Sequential maceration was conducted to obtain extracts. Total phenolic contents were determined by the Folin-Ciocalteau method. The anti-oxidant activity was assessed by DPPH free radical scavenging assay. The extracts were tested for its inhibitory activity against α-amylase in-vitro. In-vivo anti-diabetic assay was conducted using alloxan-induced diabetic model and OGTT was conducted on normal rats. ELISA was used to determine the pro-inflammatory cytokines (TNF-α and IL-6). The polyphenolic composition of the extract was analyzed using an HPLC system. RESULTS: Aqueous extract exhibited highest total phenolic contents (985.24± 3.82 mg GAE/100 g DW), antioxidant activity (IC50 = 786.70 ± 5.23 µg/mL), and alpha-amylase inhibition (IC50 =352.8 µg/mL). The aqueous extract of Tylophora hirsuta showed remarkable in-vivo anti-diabetic activity. Results were compared with standard drug glibenclamide. Alloxan induced diabetic mediated alterations in liver function enzymes, renal function determinants, and lipid parameters were significantly restored in aqueous extract treated diabetic rats. A significant reduction in pro-inflammatory cytokines (p<0.001) was observed when compared to the control group. HPLC analysis confirms the presence of quercetin, gallic acid, cinnamic acid, and p-coumaric acid. CONCLUSION: These results showed that Tylophora hirsuta possesses strong anti-diabetic and anti-inflammatory potentials and justify its folklore use for the management of diabetes.

RESUMEN

Objective: To investigate the pharmacological potential of Argemone mexicana in treating constipation and emesis by using in vitro and in vivo models.Methods: The spasmogenic and spasmolytic effects were evaluated on isolated rabbit jejunum fragments loaded in a tissue organ bath. The response was recorded with an isotonic transducer attached with Power Lab Data Acquisition System. The laxative and antiemetic activities were assessed in BALB-c mice and poultry chicks challenged with carbamylcholine and copper sulphate stimulated emesis, respectively. Results: The total phenolic and total flavonoids contents of the extract were (267.75 ± 5.77) mg GAE/g and (73.86 ± 6.01) mg QE/g, respectively. Argemone mexicana extract exerted spasmogenic effect on isolated rabbit jejunum segments with an EC50 value of 0.016 mg/mL, which was blocked by atropine (0.3 μM). Argemone mexicana extract exerted spasmolytic effect in atropine treated jejunum fragments with an EC50 value of 2.185 mg/mL. Furthermore, Argemone mexicana extract relaxed potassium (80 mM)-induced contractions (EC50: 9.07 mg/mL), similar to a standard drug verapamil. The calcium channel blocker activity was confirmed by a rightward shift of concentration-response curve of calcium in the presence of Argemone mexicana extract (1-5 mg/mL) and verapamil (0.1-1 μM). In addition, the extract increased the distance travelled by a charcoal in the gastrointestinal tract and exhibited antiemetic effect on copper sulphate induced emesis in chicks. Conclusions: Argemone mexicana shows cholinergic agonist and calcium channel blocker activities, as well as antiemetic effect. It may be used as a potential agent for treating gastrointestinal disorders.

RESUMEN

A halophytic plant, Haloxylon stocksii, is used to treat various inflammatory disorders traditionally. The present study was carried out to investigate the phytochemical parameters, anti-inflammatory, analgesic and cytotoxic potential of the whole plant extracts of H. stocksii. The plant powder was standardized for pharmacognostic parameters. It was extracted with methanol followed by chloroform, ethyl acetate and water to prepare respective fractions. Total phenolic and flavonoid contents in the extract and fractions were estimated. The anti-inflammatory potential was determined through carrageenan-induced rat paw edema model. Centrally acting analgesic activity was assessed through the hot plate method. MTT assay was used to assess the viability of Human umbilical and human hepatocyte carcinoma cell lines upon exposure to plant extract/fractions. Chloroform fraction showed the highest phenolic while ethyl acetate exhibited a maximum flavonoids content. The plant ethyl acetate fraction exhibited highest percentage inhibition of paw edema and maximum analgesic activity at 500 mg/kg dose. The plant methanolic extract and fractions showed dose dependent cytotoxic activity. The present study concludes that the extracts of H. stocksii may be effective and safe against acute inflammatory response and pain at therapeutic concentrations.

RESUMEN

BACKGROUND AND OBJECTIVE: Studies conducted across the world have reported that the rates of major adverse cardiac events (MACE) following the use of bioresorbable vascular scaffolds (BVS) are comparable to that noted with traditional drug eluting stents (DES). However, there is limited data on the immediate and medium-term clinical outcomes following the use of the Absorb BVS (Abbott Vascular, Santa Clara, SA) in the Indian context. This study was conducted to determine real-world evidence on the immediate and medium-term clinical outcomes in all patients undergoing percutaneous coronary intervention (PCI) with the Absorb BVS. METHODS: Data of all patients who were treated with Absorb BVS at our center were evaluated. Between December 2012 and October 2016, 142 patients underwent PCI with BVS. The MACE rates during hospitalization, at 30days, 3 months, 6 months after PCI, and every 6 months thereafter were the primary endpoints evaluated with median follow up of 13 months. RESULTS: Mean age of the study participants was 53.7±11.8years. Intravascular ultrasound imaging was performed in 15.34% of patients. Predilatation and postdilatation were performed in 81.8% and 84.6% of scaffolds, respectively. There were no episodes of MACE during hospitalization. However, 1 BVS-related MACE was observed at the 1-month (0.7%) as well as at the ≥12 month (0.8%) follow up visits. At the 6- and 12-month follow up visits, 2 (1.5%) and 3 (2.5%) non-BVS-related MACEs, respectively, were recorded. CONCLUSION: The use of Absorb BVS in this real-world experience was associated with very good immediate and medium-term clinical outcomes.

RESUMEN

The present study was aimed at preparation of transdermal patches of tizanidine HCl, evaluation of the effect of polymers on in vitro release pattern of the drug, and the effect of permeation enhancers on the penetration of the drug through the rabbit skin. Various proportions of hydrophilic (HPMC) and hydrophobic (Eudragit L-100) polymers were used with PEG 400 as film-forming agent, and Span 20 or DMSO as permeation enhancer. The formulations were assessed for physicochemical characteristics and in vitro drug release studies using USP paddle over disc method in phosphate buffered saline (pH 7.4) at 32.0±1°C. On the basis of in vitro studies and physicochemical evaluations, S03-A and S04-A were selected at Eudragit : HPMC ratios of 8 : 2 and 7 : 3, respectively, for further ex vivo analysis. The effects of different concentrations of Span 20 and DMSO were evaluated on excised rabbit skin using Franz diffusion cell. Cumulative drug permeation, flux, permeability coefficient, target flux, and enhancement ratio were calculated and compared with the control formulations. Kinetic models and Tukey's multiple comparison test were applied to evaluate the drug release patterns. Formulation SB03-PE containing Eudragit L-100:HPMC (7:3) with Span 20 (15% w/w) produced the highest enhancement in drug permeation, and followed zero order kinetic model with super case-II drug release mechanism.

RESUMEN

The present study was designed to evaluate the anti-inflammatory, analgesic and antipyretic activities of the aqueous and ethanolic extracts of seeds of Buchanania lanzan Spreng. Albino mice were used as experimental animals to evaluate these activities. The study was performed in three phases; Phase-I for evaluation of anti-inflammatory activity, Phase-II for antipyretic and Phase-HI for analgesic activities were evaluated. Carrageenan induced paw edema, brewer yeast induced pyrexia and acetic acid induced writhing methods were used to evaluate anti-inflammatory, antipyretic and analgesic activities, respectively. Tests were performed by dividing the animals in five groups. First group was negative control, second group was positive control, third, fourth and fifth groups were treated with 125, 250 and 500 mg/kg of extracts. respectively. The data were statistically analyzed using ANOVA where p < 0.05 were considered significant. The results suggested that seeds of Buchanania lanzan Spreng. possess anti-inflammatory, analgesic and antipyretic activity.

RESUMEN

The present study was aimed to assess biological (analgesic, antipyretic and anti-inflammatory) activities of methanolic and aqueous fruit extracts of Grewia asiatica. The study was performed on albino mice. Analgesic effect of the extracts was determined by acetic acid induced writhing. Antipyretic potential of the tested fruit extracts was assessed by brewer's yeast induced pyrexia. Carrageenan induced paw edema method was used to evaluate the anti-inflammatory activity. Both the extracts showed biological effects in a dose dependent fashion at doses 125 mg/kg, 250 mg/kg and 500 mg/kg orally. Analysis of variance (ANOVA) was used for data analysis and the values having p-value smaller than 0.05 were considered significant. Both the extracts had significant analgesic, antipyretic and anti-inflammatory activities.
