Achyranthes aspera L. (Family: Amaranthaceae) is widely used as a medicinal plant. The hydroalcholic extract of Achyranthes aspera L. leaves was screened for its analgesic activity. The dose (200 mg/kg) was tested for analgesic activity using hot plate and Tail flick test in albino mice. The hydroalcholic extract of Achyranthes aspera L. leaves showed maximum analgesic activity in hot plate at reaction time 120 min (7.40±0.08) and tail flick method at reaction time 120 min (6.9±0.06). These study suggest that the hydroalcholic extract of Achyranthes aspera L. could be considered as potential analgesic agent.

Background: Vitamin D plays vital role in physiological functions in humans through its active form Calcitriol (Vitamin D3). Vitamin D receptors are found in most tissues, attributing to its classic and non-classic actions. Calcitriol exerts important regulatory effects on the molecular pathways involved in inflammation and pain. The present study is done for experimental evaluation of analgesic action of Calcitriol using pain models in albino mice.Methods: In this prospective, experimental study, healthy Swiss albino mice were taken after permission from IAEC. Mice were divided into five groups as Control- treated with normal saline, Standard- treated with morphine and Test groups- treated with Calcitriol in dose of 15 µg /kg/mice, 30 µg /kg/mice and 60 µg/kg/mice respectively. Evaluation of analgesic activity was done using Hot plate and Tail flick analgesiometer.Results: All the 3 test doses of Calcitriol although showed prolongation of reaction time in Hot plate method up to 60 mins but the analgesic activity was not significant in comparison with the standard Morphine. With Tail flick method Calcitriol failed to show any analgesic efficacy at 15-30 μg/Kg but showed some analgesia at 60 μg/Kg which was more than control but not at all comparable with the standard Morphine for thermal pain.Conclusions: The analgesic activity of Calcitriol was exhibited at higher doses. This property needs to be further evaluated by planning extensive animal experimentation using different animal models.

Background: The objective of the study was to evaluate analgesic activity of ethanolic extract, methanol and benzene fraction of Myristica fragrans on wistar albino rats.Methods: The present study was carried out in the department of pharmacology JNMC AMU and F.H. Medical College, Agra. The analgesic activity was evaluated by employing the Eddy’s hot plate method and tail flick response method. In both the tests, Rats of either sex weighing 150-200 g were used. The total number of animals n=36 were allocated to six groups. Each group consist of six animals each. The response noted in animals that were tested by hot plate method was reaction time for licking/biting of both the paws before and after administration of control & test drugs. However in Tail flick test, the pain threshold response was recorded before and after administration of control & test drugs. The statistical analysis was done by using one-way ANOVA. The data is expressed as Mean±SEM. P<0.05 was considered to be statistically significant.Results: Ethanolic extracts and methanol fraction of M. fragrans showed statistically significant (p<0.001) increase in reaction time for licking/biting in hot plate method. On the contrary a significant increase in pain threshold was also recorded in tail flick response test. It is interesting to note that no significant degree of analgesia related to any dose of benzene fraction was observed.Conclusions: The present study reveals the dose dependent significant analgesic activity of the extracts of M. fragrans i.e. ethanolic extracts and methanol fraction in both the test. However, the degree of analgesia was recorded significantly higher in groups received higher doses of extracts of M. fragrans.

This study was conducted to determine the analgesic activity of aqueous extract of Terminalia paniculata (Tp) bark. Analgesic activity was determined using hot plate and tail flick method. Thirty adult Wistar rats were divided into 5 groups of 6 rats each. Group I (control) received 2 mL water, Group II -codeine 5 mg kg-1, Group III, IV and V 100, 200 and 400 mg kg-1 of Tp, respectively. Latency time to pain sensation was noted. In hot plate model, group 5 showed significant increase in reaction time compared to groups 3 and 4 at all-time points and was comparable to standard codeine at 120th and 180th min. In tail flick method, standard codeine showed significant increased latency time compared to all three doses of Tp at 90th, 120th and 180th min. Group 5 showed significant increased reaction time compared to groups 3 and 4 from 60th min to 180th min. Group 4 showed increased analgesic activity compared to group 3 at 90th, 120th and 180th min but group 3 was significantly better at 30th min. Thus T. paniculata possesses analgesic potential.

Background: Pain and pyrexia are the warning signals, primarily protective in nature, that cause discomfort and suffering and may even be unbearable and incapacitating. The modern drugs (like opioids, NSAIDs, corticosteroids) currently used for the management of pain, fever and inflammatory conditions, present with many known adverse effects. Tinospora cordifolia known as Giloe, widely used in folk medicine due to its property to cure a number of diseases. Hence the present study was undertaken to explore the analgesic activity of water-soluble extract of stem of T. cordifolia in albino rats in experimentally induced pain.Methods: Present study was done in the department of pharmacology, albino rats were used to study the analgesic activity of T. cordifolia aqueous extract at the dose of 1.25g/kg,2.5g/kg and 5g/kg p.o. Various methods like Eddy’s hot plate, tail flick test and acetic acid induced writhing were used for the anti- nociceptive study.Results: In Eddy’s hot plate and tail flick test an increase in reaction time was observed with peak effect at 90min. Results were similar to the standard drug Tramadol in acetic acid induced writhing increase in time of onset, decrease in number and duration of writhing was observed.Conclusions: Aqueous extract of T. cordifolia was effective in all the three models of pain suggesting its possible action by central and peripheral mechanisms. Activity of T. cordifolia can be attributed to various phytoconstituents viz. protoberberine alkaloids, terpenoids, glycosides and polysaccharides. It can be developed as potent analgesic agent in future.

The present study aims to investigate the analgesic activity of the methanol extract of the galls ofQuercus infectoriain rats using hot plate and tail-flick methods. The extract was administered intraperitoneally at a dose of 20 mg/kg while morphine sulfate and sodium salicylate (10 mg/kg) served as standards. The methanol extract exhibited significant analgesic activity in the tail-flick model (P<0.05) by increasing the reaction time of the rats to 8.0 sec at 30 min after treatment in comparison to control (4.4 sec). Morphine sulfate produced a reaction time of 11.9 sec in the same test. At the peak of activity (30 min), the extract produced maximum possible analgesia (MPA) of 34.2%, whilst morphine sulfate achieved a peak MPA of 70.9%. No analgesic effects have been observed using sodium salicylate in the tail-flick model. In the same model, the extract and sodium salicylate demonstrated comparable reaction times. Tail-flick is a better method to evaluate analgesic activity as no significant results were observed for all treatments using hot plate with the exception of morphine sulfate, which showed significant results only at 45 and 60 min after treatment. In conclusion, the methanol extract of the galls ofQuercus infectoriadisplayed analgesic activity.

Plant Parts

Opuntia ficus-indica(the cactus or prickly pear) is a cactus belonging to the Opuntiae family. Several Opuntiae plant parts have been used in traditional Moroccan medicine. In this study, we investigated its most common use as an analgesic. An ethnobotanical study ofOpuntia ficus-indicawas first conducted in 10 areas in Morocco. Extracts fromOpuntia ficus-indicacladodes were obtained using a decoction method and its analgesic activity in mice was investigated by the hot plate and tail flick methods. Cladode extracts had significant (p<0.05) analgesic activity at intraperitoneal doses of 300, 500, and 1000 mg/kg body weight. Both methods revealed significantly increased latency at all three doses (p<0.05) compared to controls. These data suggest that the traditional use of this plant as an analgesic is valid; in fact, perhaps it may be a centrally-acting analgesic.

 Objective: The objective of the study was to investigate the analgesic activity of hydroalcoholic extract of Murraya koenigii and Coriandrum sativum leaves and compared it with standard drug in an animal model.Methods: Hydroalcoholic extracts of M. koenigii and C. sativum leaves were obtained using Soxhlet apparatus. The central analgesic property was screened by hot plate method in mice and tail flick method in rats. The pain reaction time (PRT) was measured at 30, 60, and 120 min. The peripheral analgesic activity was evaluated by acetic acid induced writhing in mice.Results: In hot plate method M. koenigii leaves extract at both doses and tramadol showed significant increase in PRT at 30, 60, and 120 min compared with control group. C. sativum leaves extract showed significant increase in PRT only at 60 and 120 min compared to control group. In tail flick method M. koenigii leaves extract at both doses, higher dose of C. sativum leaves extract and tramadol showed significant increase in PRT at 30, 60, and 120 min compared with control group. Higher dose of M. koenigii leaves extract (200 mg/kg) was comparable with standard drug tramadol in both the methods. M. koenigii leaves extract at both dose showed significant reduction in the number of writhing but C. sativum leaves extract failed to show any significant reduction in the number of writhing compared with control. Higher dose of M. koenigii leaves extract was comparable with standard drug tramadol.Conclusion: M. koenigii leaves extract showed both peripheral and central analgesic effect while C. sativum leaves extract showed only peripheral analgesic effect.

Previously, we synthesized a dimeric dipeptide mimetic of the brain-derived neurotrophic factor (BDNF) loop 4, GSB-106, which, similarly to BDNF, activated TrkB, PI3K/AKT, and MAPK/ERK. When administered systemically, it exhibited neuroprotective, antidepressant, and antidiabetic activities and stimulated neurogenesis and synaptogenesis. In this study, we established that GSB-106 also exhibits the analgesic activity, typical for BDNF, which was revealed in rats in hot plate and tail flick tests 0.5–48 h after intraperitoneal injection at doses of 0.1 and 1 mg/kg.
