Major Clinical Problem

Pain represents a major clinical problem and one which has exercised generations of healthcare professionals. Earthworms are used as a traditional Chinese medicine, and have been applied pharmacologically and clinically since a long time in China. However, the analgesic effects of earthworm extract (EE) are seldom studied. Hence, we evaluated the analgesic effects of EE in mice. The obtained data showed that EE increased pain threshold and exhibited peripheral but not central analgesic effects in mice; evidenced by increased inhibition ratio in acetic acid writhing test and formalin test, whereas only slight increase in inhibition ratio in hot plate test and tail immersion test. In addition, EE decreased serum norepinephrine (NE), 5-hydroxytryptamine (5-HT), and nitric oxide (NO) synthase (NOS) concentration, similar to other analgesic drugs like morphine and aspirin. In a nutshell, the obtained data have demonstrated that EE has peripheral analgesic properties and could be used as a promising analgesic drug.

Chinese Propolis

Propolis is an important bee product which has been applied to the treatment of several diseases. The aim of this study was to understand the material basis of Chinese propolis on pain relief; different Chinese propolis fractions (40W, 40E, 70E, and 95E raw propolis extracted followed by 40%, 70%, or 95% ethanol) were prepared, and their antinociceptive effects were evaluated. By analyzing using UPLC-Q-TOF-MS, we showed that 40W was rich in phenolic acids, like caffeic acid, while 40E, 70E, and 95E have relatively high levels in flavonoids, like galangin, pinocembrin, and chrysin. Notably, chrysin amounts in 70E and 95E are much higher than those in 40E fraction. Antinociceptive effects by these propolis fractions were evaluated in mice using acetic acid-induced writhing test, hot plate test, and tail immersion test, respectively. We noticed that only 40E fraction showed a significant reduction on acetic acid-induced writhing test. Importantly, in the hot plate test, all groups showed their effectiveness, except for the 70E group. We also noticed that 40W, 40E, and 95E administration caused an increase in the tail withdrawal latency of the mice. These data suggested that the different antinociceptive effects of different fractions from Chinese propolis extracts are directly link to their flavonoid composition.

Background: The concept of analgesic effects of thiamine along with other B vitamins has been supported since long by various clinical and experimental evidences, though effects of individual thiamine on pain are yet to be clearly demonstrated.Objective: To assess the effects of increasing doses of thiamine supplementation on pain.Methods: Forty-eight (48) male Long Evans rats (200±20 gm) were given thiamine (100, 200, 250, mg/kg/day; experimental) or normal saline (5 ml/kg/day; control) intraperitonealy (i.p) for 7 consecutive days. The analgesic activity was evaluated by three experimental pain models, hot (52±0.50C) water tail immersion test, the interphase (6th-15th minutes) of formalin (50?l, 2.5%, subcutaneous) test and acetic acid (2%, i.p) induced writhing test. Statistical analysis was done by ANOVA followed by Bonferroni post hoc test and p?0.05 was considered as significant.Results: In tail immersion test, %MPE significantly increased after 200 (p?0.05) and 250 (p?0.001) mg/kg of thiamine. In the formalin test, thiamine significantly lowered the jerking frequency (p?0.05, p?0.001, p?0.001, respectively) and duration of flexing and licking (p?0.001, in all doses), compared to control. In addition, in writhing test, significant increment in latency of appearance of 1st writhe (p?0.001, in higher 2 doses) and significant decrement in frequency of writhes (p?0.01, p?0.001, p?0.001, respectively, in all doses) were observed.Conclusion: The results of this study conclude that, repetitive administration of thiamine may cause alleviation of pain through central as well as peripheral inhibitory mechanisms, which is dose dependent as well.Bangladesh Soc Physiol. 2017, June; 12(1): 1-9

The present study was carried out to investigate the possible analgesic, neuropharmacological and cytotoxic activities of the methanolic extract of Trigonella foenum-graecum Linn. leaves. The analgesic and neuropharmacological activities of Trigonella foenum-graecum Linn. were investigated at the doses of 100mg/kg, 200mg/kg and 400mg/kg of body weight in mice. Analgesic potential of the extract was evaluated for centrally acting analgesic property using tail immersion method and peripheral analgesic actions using acetic acid-induced writhing test. In acetic acid-induced writhing test, extract produced a significant (p < 0.001) inhibition of writhing response in a dose dependent manner but maximum inhibition (93.46%) of writhing was found at 400mg/kg dose. In tail immersion method, extract caused a significant (p < 0.001) increase in latency time and the results were comparable to the standard drug Diclofenac- Sodium. In addition, neuropharmacological property of crude extract was carried out by Hole cross and Open field test. The extract significantly (p < 0.05-0.001) displayed a dose dependent suppression of motor activity, exploratory behaviour. Furthermore, the extract was subjected to Brine Shrimp lethality bioassay for primary evaluation of cytotoxicity, where the extract was found to be highly toxic to Brine Shrimp nauplii, having LC50 values of 10μg/ml while the LC50 of the reference anticancer drug vincristine sulphate was 0.66μg/ml. The results of this present study suggest that the extract possesses analgesic, cytotoxic and CNS depressant activities.

In folk medicine, Polyalthia suberosa is used as abortifacient, laxative, febrifuge analgesic, filler of tooth cavities, and anti-HIV drug and for rheumatism and various skin infections. The present study was directed to evaluate the analgesic and anti-inflammatory activities of diethyl ether and n-hexane extracts of Polyalthia suberosa leaves (PSDE and PSNH). A variety of tests including formalin-induced paw licking test, acetic acid induced writhing test, and tail immersion test were used to assess the analgesic activity. In addition, xylene-induced ear edema test was used to evaluate anti-inflammatory activity of PSDE and PSNH. PSDE and PSNH at 200 and 400 mg/kg doses expressed analgesic as well as anti-inflammatory activities in mice. In formalin-induced paw licking test, acetic acid induced writhing test, and xylene-induced ear edema test, the extracts exhibited significant inhibition (P⁎<0.05 versus control) of pain and inflammation. Alternatively, in tail immersion test, PSDE 400 mg/kg showed significant (P⁎<0.05 versus control) latency at 30 min but another tested sample had no significant latency. From this study, it could be shown that Polyalthia suberosa leaves may contain analgesic and anti-inflammatory agents which support its use in traditional medicine.

Pupalia lappacea Juss (Family: Amaranthaceae) is claimed to be useful in treatment of bone fracture, wounds, boils, cough, toothache, fever and malaria. The study was aimed to evaluate the 80% aqueous ethanolic extract of aerial parts of P. lappacea for antinociceptive and antipyretic activities to verify the traditional claim. The extract was orally administered at doses of 200, 400 and 600 mg/kg. The extract has significantly (P<0.01) reduced the nociception induced by acetic acid. The effect produced was in dose dependent manner. The antinociceptive effect was not reversed by pretreatment with naloxone in acetic acid induced writhing test. In hot plate method, the extract has significantly increased the latency time of jump. The naloxone has partially antagonised the antinociception of extract in hot plate test indicating P. lappacea has morphinomimetic properties. In the study of the CNS-depressant effects, the extract was found to produce significant reduction in head pokes and locomotion in mice by using hole board and locomotor activity test respectively. The extract has significantly reduced the rectal temperature in yeast induced pyrexia in rats at 600 mg/kg. The activity produced by extract was in dose dependent manner. Phytochemical investigation of ethanolic extract of P. lappacea revealed the presence of steroids and/or triterpenoids, flavonoids and phenolic compounds which may be responsible for antinociceptive and antipyretic activity of P. lappacea.DOI: http://dx.doi.org/10.3329/icpj.v2i2.13193 International Current Pharmaceutical Journal 2013, 2(2): 23-28

Background: Dacryodes edulis leaf extract is used in traditional settings in management of many disease conditions including pain and inflammation. However, these empirical claims have not been evaluated scientifically. Objective: The objective of this study was to determine the effect of ethanol leaf extract of Dacryodes edulis on pain and inflammation using rodents. Materials and Methods: Writhing test using acetic acid for induction of pain and tail-immersion in temperature controlled water were used to study the effect on pain sensation while xylene-induced ear oedema and carrageenan-induced paw oedema were used for the effect of Dacryodes edulis on inflammation. Male mice divided into seven groups and three different doses of extract viz,100mg/kg, 200mg/kg and 400mg/kg based on the results of the acute toxicity study and the mean effective dose study, ED50 were used for the study. Ethical approval was obtained from the Faculty of Basic Medical Sciences, University of Calabar Animal Research Ethics Committee with number: 012PA31116. Results: 400mg/kg extract showed significant analgesic activity having 75% inhibition of pain in the writhing test while aspirin showed 80% inhibition of pain. The extract also significantly (p<0.05) prolonged flick latency period comparable to morphine in tail immersion test. The extract caused 72% inhibition of xylene induced ear oedema compared to 91% of dexamethasone. Similarly it showed comparable activity (p<0.05) with aspirin in the carrageenan-induced paw oedema. Conclusion: Dacryodes edulis leaf extract has activity against pain and inflammation. This validates its application in management of inflammation and pain in local settings.

Preliminary phytochemical screening of the methanolic extract of the whole plant of Saccharum spontaneum Linn. (Family- Gramineae) revealed the presence of alkaloids, flavonoids, reducing sugar, tannins and saponins. The antidiarrhoeal activity of the extract (200 and 400 mg/kg) was assessed on experimental animal and a dose dependent decrease in the total number of faecal dropping was obsereved in castor oil induced diarrhoea in mice. The plant extract was also assessed for effect on the central nervous system (CNS) using a number of neuropharmacological experimental models in mice. The extract produced a dosedependent reduction of the onset and duration of pentobarbitone-induced hypnosis, reduction of locomotor and exploratory activities in the open field and hole cross tests. These results suggest that the extract possesses antidiarrhoeal and CNS depressant activity. Key Words: Saccharum spontaneum, Castor oil, Loperamide, Pentobarbitone.     doi:10.3329/sjps.v1i1.1810 S.
