The anti-inflammatory activity of hydroxytriazenes as well as their vanadium complexes has been studied using carrageenan induced hind paw oedema method in albino rats (Wister strain). Hydroxytriazenesviz., 3-hydroxy-1,3-diphenyltriazene(HT-1), 3-hydroxy-3-phenyl-1-(4-sulfonamido)phenyl triazene(HT-2), 3-hydroxy-3-p-chlorophenyl-1-(4-sulfonamido) phenyltriazene(HT-3), 3-hydroxy-3-m-chlorophenyl-1-(4-sulfonamido)phenyltriazene(HT-4)(HT-4) and their respective vanadium complexes C-1, C-2, C-3 and C-4 have been synthesized using standard methods, purified, characterized and used for studying their anti-inflammatory activities. The hind paw oedema was produced by subplanter injection of carrageenan and the paw volume was measured plethysmographically after 0.5, 1, 2, 3 and 5 h. The animals were givenHT-1, HT-2, HT-3andHT-4and also vanadium complexes C-1, C-2, C-3 and C-4 dissolved inDMSO(at dose 5 mg/Kg body weight). Diclofenac sodium (5 mg/kg) was used as a standard drug. The standard drug shows maximum inibition up to 1h as 81.73% which goes on increasing up to 3h (88.94%) but further reduces to 74.93% at the end of 5 h. The test compounds i.e. both ligands as well as their metal complexes show maximum percent inhibition only up to 1h. after which the efficacy reduces. Thus it can be said that both ligands as well as their vanadium complexes show very significant anti-inflammatory activity up to 1h which is comparable to standard drug.

Aim: In this study, the methanol stem bark extract of Detarium microcarpum was evaluated for sub-chronic, biochemical and histopathological studies. Methodology: Sub-chronic toxicity studies was investigated in rats administered with 35, 70 and 140 mg/kg doses of the extract orally for 28 days using standard laboratory procedures after the acute toxicity was carried out. Results: The median lethal dose (LD50) of the extract was calculated to be equal to (≥) 5000 mg/kg body weight in rats orally. Serological studies revealed significant (p<0.05) decrease in Alanine aminotransferase (ALT) at all doses tested, while at 140 mg/kg it caused a significant (p<0.05) increase in Alkaline Phosphatase (ALP). At doses of 70 and 140 mg/kg there was a significant (p<0.05) reduction in creatinine level. Histopathological studies on the liver showed moderate hepatocellular necrosis at doses of 35 and 70 mg/kg, while at 140 mg/kg there was intense hepatocellular necrosis,  Kupffer cells and lymphocytes hyperplasia. The Kidney showed intense necrosis of tubules and glomerular necrosis with lymphocytes hyperplasia at all doses tested.  The spleen also showed intense lymphocyte hyperplasia at all doses with sinusoidal congestion at the lowest dose of 35 mg/kg. The heart showed slight necrosis of cardiac muscle cells at all doses with blood congestion at 35 and 70mg/kg body weight. Conclusion: The study indicates that prolong use of the extract in the management of disease conditions may be associated with some adverse effect of some vital organs.

Oral Acute Toxicity

Aim: Frankincense tree (Boswellia dalzielii) and Kenaf (H. cannabinus) are plants abundantly found in north-western Nigeria. These plants are very popular among the locals as potent sources of ethno medicine. The present study investigates the oral acute toxicity potentials of methanolic stem bark extract of frankincense tree and Kenaf leaves, as well as sub-chronic toxicity potentials of the plants extracts on the kidney and liver of Albino rats. Study Design: Laboratory-experimental design was used for this study. Place and Duration of Study: This study was carried out between September 2019 and November 2019 at Biochemistry laboratory, Sokoto State University, Sokoto, Nigeria. Methodology: For the oral acute toxicity study, the revised “Up and Down” test (Limit Dose Test) was used to determine the LD50 of the extracts. For sub-chronic toxicity study, twenty albino rats were used for each plant, and were divided into four groups of five animals each. Group I (control), Group II (received 200 mg extract/kg body weight), Group III (received 400 mg extract/kg body weight) and Group IV (received 800 mg extract/kg body weight). All administrations were given orally for 28 days. Liver and kidney markers were determined using standard methods. Result: The oral acute toxicity test of the plant extracts at 3000 mg/kg body weight showed no mortality for 24 hours and subsequent 14days of administration. LD50 for both plants is therefore greater than 3000 mg/kg. The result shows no significant differences (p > 0.05) on liver and kidney function biomarkers investigated when Group II, III and IV are compared with control. Conclusion: This suggests that Frankincense stem bark and kenaf leaves extracts may be safe in rats at doses less than or equal 3000 mg/kg.

The antinociceptive activity of the methanolic extract of the leaves of Feronia limonia Linn. (Family Rutaceae) was investigated using acetic acid-induced writhing model and tail flick test in swiss albino mice. The extract produced about 26.01% ( p< 0.01), 39.88% ( p< 0.01) and 57.07% (p< 0.01) writhing inhibition at the dose of 100, 200 and 400 mg/kg of body weight respectively, which was comparable to the standard drug diclofenac sodium where the inhibition was about 63.58% (p< 0.01) at the dose of 25 mg/kg of body weight. All doses of extracts significantly (p<0.05) increased latency of flick tail in tail immersion method. The methanolic extract showed dose dependent antinociceptive activity in both type of test in swiss albino mice. Phytochemical investigations of the leaves extract indicate the presence of tannins, saponins, steroids, alkaloids and flavonoids. The preliminary study of the methanolic extract showed antinociceptive activity in both writhing and tail flick test in mice. http://dx.doi.org/10.3329/bjpp.v26i1-2.19962 Bangladesh J Physiol Pharmacol 2010; 26(1&2) : 21-24

Objective: This study investigated the anti-nociceptive and anti-inflammatory activities of the aqueous extract of Ficus capensis (AEFC) by bio-guided fractionation. Methods: The anti-nociceptive and anti-inflammatory effects of AEFC (250, 500, 1000 mg/kg, i.p) were assessed using acetic acid-induced writhing, hot plate, tail-flick, formalin tests, and carrageenan-induced paw oedema respectively. The AEFC was fractionated base on polarity different into butanol, ethyl acetate, and n-hexane fractions. The fractions (500 mg/kg) obtained were subjected to the same experimental procedures mentioned above. The EAF, which exerted the most productive activities, was further subjected to fractionation procedures that yielded six fractions (labeled CF1-CF6). These fractions (200 mg/kg) were tested for potential anti-nociceptive and anti-inflammatory activities. Notable antagonists (Naloxone and atropine) of nociceptive pathway were used to evaluate the mechanism of the anti-nociceptive action of F. capensis. Results and Discussion: The AEFC, BF, EAF, and CF4 caused a significant (p<0.05) reduction in the number of abdominal writhes, an increase in reaction time against the hot plate, tail-flick tests, and a significant (p<0.05) inhibition in both phases of formalin test. The AEFC, BF, EAF, CF4, and CF6 caused a significant (p<0.05) inhibition of paw oedema development due to carrageenan. Atropine significantly reversed the anti-nociceptive effect of CF4 in both phases of the formalin test. The result obtained revealed that CF4 produced central and peripheral anti-nociceptive effects, while CF6 is peripherally mediated. Conclusion: The results support the traditional uses of F. capensis in the treatment of various diseases associated with pain and inflammation. The column fraction CF4 exhibited muscarinic receptor-mediated anti-nociceptive activity.

Background: Pain is the most common reason patients seek medical care. Increased level of monoamines (serotonin and norepinephrine) in synaptic clefts lead to changes in pain threshold and induce antinociception. The study was carried out to evaluate antinociceptive effect of paroxetine in albino rats and to probe into its possible mechanism of action. The study was carried out to evaluate anti-nociceptive effect of paroxetine in albino rats.Methods: Male Albino rats of average weight 150-240gms were used. The drugs used were paroxetine 5mg/Kg, pethidine 5mg/kg (standard drug). Anti-nociceptive effect tested by using thermal method i.e. Tail flick response and Tail warm water immersion method.Results: In this study, Anti-nociceptive effect of respective drugs were measured by using two methods i.e. tail flick test and tail warm water immersion method at 0 min., 30 min., 60 min. and 90min.after administration of drugs. Reaction time started to increase from baseline at 0 min. and peak effect was seen at 60 min. then it started to decrease at 90 min. in almost all the groups except in control group.Conclusions: Paroxetine have significant analgesic effect in acute pain, which may be mediated via central and peripheral mechanisms. Efficacy of Paroxetine is almost equal to that of standard drug pethidine in acute pain management.

Objective: The objective of this work was to validate the traditional claim of the use of the stem bark of Berlinia grandiflora in treating liver problems by investigating the effect of its ethanol stem bark extract on maker liver enzymes in vivo.Methods: Groups of Wistar albino rats (6 in each group) were daily treated with CCl4 (2 ml/kg b.w., diluted with olive oil 1:1 v/v, intravenously), followed by oral administration of ethanol stem bark extract of Berlinia grandiflora (ESBG) at doses 100, 300 and 900 mg/kg b.w. respectively, 3 h after the administration of the CCl4. Serum biochemical parameters were measured 24 h at the end of the 7-day treatment period and compared to a group intoxicated with CCl4 (2 ml/kg b.w., diluted with olive oil 1:1 v/v, intravenously) alone.Results: Treatment of rats with ESBG (at doses 100, 300 and 900 mg/kg b.w. orally) reduced the impact of CCl4-induced hepatotoxicity on liver maker enzymes Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP) and total bilirubin (TB), with the 900 mg/kg b.w. showing a significant reduction (p<0.05) compared to the group intoxicated with CCl4. The extract reversed the impact of the CCl4-induced hepatotoxicity by increasing the concentration of the serum Total protein (TP) and albumin (ALB), with the 900 mg/kg b.w. dose showing a significant increment (p<0.05) compared to the group intoxicated with the CCl4.Conclusion: The investigation of the effect of Berlinia grandiflora on CCl4 induced liver damage revealed that the ethanol extract of the stem bark of the plant was able to reverse the hepatotoxicity, with the 900 mg/kg b.w. dose showing a significant activity.
