Granuloma maturation in the rat is advanced by the oral administration of Eucommia ulmoides OLIVER leaf

We have reported that collagen metabolism was improved by the administration of Eucommia ulmoides OLIVER leaf. In this paper, we examine the granuloma maturation and deposition of collagen in the granuloma of rats due to the oral administration of this leaf. After 3 weeks of the oral administration, granuloma formation was induced by the formalin soaked filter paper-pellet method. A week later, the developing granuloma was dissected. Granuloma formation was significantly increased due to ingestion of the dried leaf at a dose of 1.8 g/kg of body weight/d. The collagen content in the granuloma was also significantly increased. In the case of the collagen profile, the pepsin-solubilized collagen content and its relative percentage to the total collagen were significantly higher than in the control. Histochemical examination showed that the granuloma tissues were well developed, and displayed many newly synthesized capillary vessels and a greater quantity of fibroblasts and monocytes in the 1.8 g leaf group. High density lipoprotein (HDL)-cholesterol and triglyceride content in the blood plasma were significantly higher than in the control. These results show that granuloma maturation was accelerated and the energy was supplied from fatty acid metabolism. The administration of Eucommia ulmoides OLIVER leaf may be effective at speeding up the wound healing process.

Analgesic and anti-inflammatory effects of Ranunculus japonicus extract.

The analgesic and anti-inflammatory effects of Ranunculus japonicus extract after parenteral administration were determined in several animal models. The extract inhibited the mice writhing responses caused by acetic acid and raised the pain thresholds of mice in the hot-plate test. The extract also inhibited the paw edema of rats induced by carrageenin, ear swelling of mice caused by xylene, mice vascular permeability increase induced by acetic acid, and granuloma formation in rats.     

Study of anti-inflammatory and antinociceptive activity of hydroalcoholic extract of Schima wallichii bark

Hydroalcoholic extract of Schima wallichii Choisy. (Ternstroemiaceae) bark (HESW) was investigated for its anti-inflammatory, antinociceptive, and antipyretic activities. The anti-inflammatory effects of the HESW were assayed by using carrageenan and dextran (acute model) induced paw edema and cotton pellet granuloma assay (chronic model) in experimental rats. Oral administration of HESW at the doses of 150 and 300?mg/kg caused dose-dependent inhibition of carrageenan and dextran induced inflammation. HESW at the doses of 150 and 300?mg/kg caused significant dose-dependent reduction of the granuloma tissue formation in experimental rats. The extract at the oral doses of 50 and 100?mg/kg body weight exhibited significant central and peripheral analgesic activity in acetic acid induced writhing test and hot-plate test respectively in experimental mice. Treatment with HESW at the oral doses of 150 and 300?mg/kg body weight significantly reduced the yeast-provoked elevated body temperature in experimental rats in a dose-dependent manner.

Evaluation of the anti-inflammatory property of the extract of <Emphasis Type="Italic">Combretum micranthum</Emphasis> G. Don (Combretaceae)

A methanol extract of Combretum micranthum leaves was studied for anti-inflammatory activity in rats and mice using the carrageenan-induced rat paw oedema and the acetic acid-induced vascular permeability in mice. The effect of the extract on cellular-type inflammation was also investigated in the cotton pellet granuloma in rats. The extract (50, 100 mg/kg) significantly (P < 0.05) inhibited oedema production induced by carrageenan in rats. Increased vascular permeability caused by acetic acid injection was also inhibited by the extract, within the same dose range. C. micranthum extract (100 mg/kg) inhibited granuloma formation in rats to a similar degree as indomethacin (5 mg/kg). These results provide evidence for the anti-inflammatory property of C. micranthum leaves.     

Acute Ethanol Intoxication Decreases Subsequent Food Intake and Changes Hepatic Microsomal Enzyme Activities Similarly to Fasting

Abstract: The effect of intragastric ethanol, 7.8 g/kg, on the microsomal enzyme activities NADPH cytochrome c reductase, aminopyrine N-demethylase and aniline hydroxylase, were investigated in two sizes (150 g and 260 g) of mature male rats having free access to food and water for the 23 hours following ethanol administration. Controls received intragastric water and were given free access to food and water (fed controls) or only water (fasted controls). The ethanol group had a significantly lower food intake than the fed control group, and food intake in the large rats was more decreased by ethanol than that of the small rats, corresponding to slower recovery from intoxication. Ethanol and fasting increased aniline hydroxylation and decreased acetone enhancement of aniline hydroxylation to the same degree, whereas only fasting caused a significant decrease in aminopyrine N-demethylation. Some of the effects of acute ethanol intoxication on hepatic microsomal enzyme activities appear to be mediated via decreased food intake.

Evaluation of anti-inflammatory activity of chloroform extract of Bryonia laciniosa in experimental animal models

The anti-inflammatory effect of the leaves of Bryonia laciniosa was evaluated using carrageenan, dextran, histamine, serotonin induced rat paw oedema and cotton pellet induced granuloma (chronic) models in rats. In mice, carrageenan peritonitis test was performed for the extract by oral administration. The chloroform extract of Bryonia laciniosa (CEBL) exhibited significant anti-inflammatory effect at the dose 50, 100 and 200 mg/kg. Maximum inhibition (52.4%) was noted at the dose of 200 mg/kg after 3 h of drug treatment in carrageenan induced paw oedema, whereas the indomethacin (standard drug) produced 62.1% of inhibition. The extract exhibited significant anti-inflammatory activity in dextran induced paw oedema in a dose dependent manner. The extract also exhibited significant inhibition on the hind paw oedema in rats caused by histamine and serotonin respectively. In the chronic model (cotton pellet induced granuloma) the CEBL (200 mg/kg) and standard drug showed decreased formation of granuloma tissue by 50.1 and 57.3% (p<0.001) respectively. The extract also inhibited peritoneal leukocyte migration in mice. Thus, the present study revealed that the chloroform extract of Bryonia laciniosa exhibited significant anti-inflammatory activity in the tested models.
