RESUMEN
Objective: To investigate the effect of methanolic extract of Dioclea reflexa Hook F seed on male rats following single (acute) or repeated (chronic) carbon tetrachloride intoxication. Methods: Male albino rats were divided into groups of six each consisting of plant extract only, plant extract + carbon tetrachloride, solvent only, solvent + carbon tetrachloride, vitamin E only, vitamin E + carbon tetrachloride and untreated control. The rats in the acute experiment received the extract (5mg/kg) by intraperitoneal injection for two days, and 1 hour after administration of CCl4 (0.6ml/kg body weight) on the third day, while those in the chronic experimental model received 2.5mg/kg for 10 consecutive days with 72 hourly administration of CCl4 at 0.3ml/kg. Results: In the acute model, the level of total bilirubin and conjugated bilirubin were significantly (P<0.05) reduced in D. reflexa seed extract pre-treated rats compared to the CCl4 control, while in the chronic model, the level of packed cell volume (PCV) and hemoglobin were significantly (P<0.05) boosted in extract treated group compared to the CCl4 control group with concomitant reduction in the levels of bilirubin. Conclusion: These results indicate that the seed of D. reflexa possess capacity to boost haematological parameters and protect the kidney against acute and chronic toxicological challenges.
RESUMEN
OBJECTIVE@#To explore the analgesic, antipyretic, anti-inflammatory, hepatic and nephritic effects of Pulicaria arabica (P. arabica) in several experimental models.@*METHODS@#For analgesic effect hot plate and writhing method were used, while for antipyretic and anti-inflammatory rectal temperature and carrageenan induced hind paw edema were used respectively. CCl4 intoxication method was used for hepatic and nephritic protective activity.@*RESULTS@#The results of the present studies revealed that P. arabica has potent analgesic, antipyretic and anti-inflammatory with the significant hepatic and nephritic protecting actions. The CCl4 intoxication changed the normal malondialdehyde and nonprotein sulfhydryls levels in both liver and kidney. These changes were normalized with P. arabica indicating the antioxidant nature of this plant.@*CONCLUSIONS@#The results of present study indicated that P. arabica can be used in analgesic, antipyretic and anti-inflammatory conditions even in hepatic and nephritic conditions. More supportive studies are required before clinical recommendation.
RESUMEN
The suppression of immune system leads to the development of several chronic illnesses; in replying to this the available allopathic system of medicine is provided with limited tools for treatment and prevention. In this context, the present investigation focuses on immunostimulant properties of an aqueous extract of Tinospora cordifolia in splenic macrophages isolated from carbon tetrachloride induced immunosuppressive mice. Our results suggested that carbon tetra chloride intoxication (0.5ml/Kg body weight) significantly altered the functional status like morphology, cell adhesion, phagocytosis, myeloperoxidase (MPO) release, nitric oxide (NO) release, DNA fragmentation and killing capacity of splenic macrophages. However administration of aqueous fraction of Tinospora cordifolia stem parts at a dose of 40 mg/kg body weight (in vivo) in CCl4 intoxicated male albino mice ameliorated the effect of CCl4, as was evident from the scanning electron micrographs, percentage of morphologically altered macrophages, phagocytosis activity, cell adhesion, MPO release, NO release, DNA fragmentation and intracellular killing capacity. Thus, it has been coclude that bioactive compounds presents in polar fractions of Tinospora cordifolia were accountable for boosting the immune system.
