The effect of spirobromin and prospidin on acute and chronic inflammation in rats

The effects of new antitumor drugs spirobromin and prospidin on acute (carraghenin-induced rat paw edema) and chronic ("pellet granuloma") inflammation in rats were studied. The drugs were found to exert the anti-inflammatory effect on the model of chronic proliferative inflammation but to produce no significant changes in the degree of the acute inflammatory reaction. Spirobromin is superior to prospidin by the power of the anti-inflammatory effect. The electron microscopic studies showed that spirobromin and prospidin decrease the activity of fibroblasts in the focus of chronic inflammation.

Anti-inflammatory properties of plant flavonoids. Effects of rutin, quercetin and hesperidin on adjuvant arthritis in rat.

The anti-inflammatory activities of three flavonoids were investigated in rats using the Mizushima et al. model of acute and chronic inflammation. Intraperitoneal administration of rutin, quercetin (flavonols) and hesperidin (flavanone), given at daily doses equivalent to 80 mg/kg, inhibited both acute and chronic phases of this experimental model of inflammation. Rutin was the most active in the chronic phase.     

The antiinflammatory potential of phenolic compounds from <Emphasis Type="Italic">Emblica officinalis</Emphasis> L. in rat

Antiinflammatory effects of phenolic compounds from Emblica officinalis were evaluated in carrageenan and cotton pellet induced acute and chronic inflammatory animal model. Fractions of E. officinalis containing free (FPEO) and bounded (BPEO) phenolic compounds were assessed by HPLC technique. The free and bound phenolic compounds were studied for their acute and chronic antiinflammatory activity at dose level of 20 and 40 mg/kg. The carrageenan induced acute inflammation was assessed by measuring rat paw volume at different time of intervals. Further, cotton pellet induced chronic inflammation was assessed by granulomatous tissue mass estimation along with the estimation of tissue biomarker changes (i.e. lipid peroxidation, reduced glutathione, myeloperoxidase and plasma extravasation). The results indicated that in both acute and chronic inflammation, FPEO and BPEO show reduction in the inflammation, but significant effects was observed only at high doses of both fractions which was comparable to diclofenac treated group. In conclusion, phenolic compounds of E. officinalis may serve as potential herbal candidate for amelioration of acute and chronic inflammation due to their modulatory action of free radicals.

Experimental models of acute and chronic sialoadenitis in the guinea pig.

Acute and chronic sialoadenitis were induced in ovalbumin-immunized guinea pigs by a single or repeated (once a day for 5 days) instillation of antigen into the parotid gland via the parotid duct. The acute sialoadenitis was characterized by infiltration of inflammatory polymorphonuclear leukocytes and the chronic one, by extensive tissue destruction together with infiltration of mononuclear leukocytes. In acute sialoadenitis, myeloperoxidase activity in the parotid gland, which was a marker of accumulation of neutrophils, was elevated, but in the chronic stage, it returned nearly to the control level. This observation is in accord with the histological findings that infiltrating cells in acute and chronic sialoadenitis were mainly polymorphonuclear and mononuclear leukocytes, respectively. Although cyclophosphamide suppressed the inflammation, both in acute and chronic sialoadenitis, indomethacin exerted its anti-inflammatory effect only in the acute stage. Our experimental models of acute and chronic sialoadenitis were easy to prepare, and had a high incidence. As the typical features of inflammatory development from acute to chronic phases were observed in these models, these models may be useful for studying the mechanism of the chronic course in immunologically induced inflammation and the effects of drugs on each phase and the chronic course of inflammation.     

Adrenalectomy potentiates the anti-inflammatory activity of a calcium channel blocker

Calcium movement is important in the activation of inflammatory cells. Prior studies have shown that calcium channel blockers (CCBs) inhibit carrageenan-induced paw edema in rats by acting at pituitary and hypothalamic levels. Here we evaluated the role of calcium channel blockers and their regulation via the hypothalamus-pituitary-adrenal (HPA) axis in acute and chronic models of rat paw inflammation, using both carrageenan (acute) and formalin (chronic) as inflammation inducers. Adrenalectomized (ADX) and intact Sprague Dawley rats (n = 4 per group) weighing 150-250 each were treated with an intraperitoneal injection of nifedipine (400 microg/kg) or vehicle. Edema was assessed plethysmometrically by evaluating paw volume changes. The results show a significant contradiction between acute and chronic inflammation data. In intact animals, nifedipine demonstrated a significant anti-inflammatory effect in the acute inflammatory model but not in the chronic model. In adrenal-ectomized animals, the anti-inflammatory effect of nifedipine was significantly enhanced both in acute and chronic models. We conclude that adrenalectomy plays a significant role in modulating the inflammatory pathway in the presence of calcium channel blockers.
