In our previous study, we observed that there was a close relation between the therapeutic effect and the warm receptors (WRs) or polymodal receptors (PRs). In accordance with the most sensitivity of WRs and the thermal threshold value, we used computer controlled projector light at a constant temperature 40°C and 47°C to irradiate (moxibustion) Dazhui (GV 14) and Baihui (GV 20) (it is located between the spines of the 7th lumbar vertebra and the its sacral vertebra in the rabbit) and observed its antipyretic action on fever induced by intravenous injection of endotoxin in the rabbit. Results showed that this kind of moxibustion at 40°C had no significant effect while that at 47°C had a very striking antipyretic effect, indicating that the antipyretic effect of moxibustion is mediated primarily by PRs. This fact also provides an important experimental evidence for moxibustion treatment of heat syndrome of traditional Chinese medicine (TCM). 展开更多

Objective: To evaluate the scientific basis for the use of Kang 601 heji(K-601) as an anti-in flammatory and antipyretic agent using appropriate animal models.Methods: Carrageenan-induced rat paw and xylene-induced ear oedemas were models used to investigate anti-in flammatory actions of K-601. Lipopolysaccharide-induced pyrexia model was used to evaluate antipyretic activity in Wistar rats. The antiin flammatory and antipyretic mechanisms were evaluated by detecting prostaglandins E2, nitric oxide, interleukin-1b and tumour necrosis factora levels using appropriate reagents and ELISA kits.Results: The results revealed that K-601 reduced the level of in flammations in both antiin flammatory models in a dose-dependent manner. The same was true for the antipyretic model. The possible mechanisms of actions were through the inhibition of prostaglandins E2, interleukin-1b, tumour necrosis factora and nitric oxide.Conclusions: K-601 has proven anti-in flammatory and antipyretic actions. The findings provide a scientific basis for the use of K-601 as anti-in flammatory and antipyretic agent in traditional Chinese medicinal practice. 展开更多

Objective: To evaluate the other pharmacological actions of silymarin in Albino rats and mice such as antipyretic, anti-inflammatory, antinociceptive and antihyperlipidemic effects. Methods: Rats were injected intramuscularly with pyrogenic dose of brewer's yeast for the antipyretic test of silymarin. Another group of rats injected with 0.1 mL of 1% carrageenan solution in saline at the subplanter area of the right hind paw for the anti-inflammatory test of silymarin. Another group of mice tested by hot plate method for determination of antinociceptive effect of silymarin. Hyperlipidemia was induced using high fat diet for 2 months to estimate the antihyperlipidemic activity of silymarin. Results: Silymarin showed a significant antipyretic effect of both doses(50 and 100 mg/kg) compared with control untreated group. Moreover, silymarin elucidated a significant anti-inflammatory effect of both doses reflected on the decrease of the rat paw edema every hour interval for 4 h after administration in comparison with control positive group. By the same taken, both doses of silymarine revealed a significant antinociceptive action in hot plate method at 30 and 60 min post administration. Besides, it lowered significantly the serum levels of prostaglandin E2, tumor necrosis factor alpha and interleukin 1 beta after 2 h of silymarin administration in carrageenan induced rat paw edema besides the significant decrease of total cholesterol, triglycerides, low density lipoprotein and significantly elevated high density lipoprotein after 2 weeks of silymarin administration. Conclusions: These outcomes delivered a new vision into the possible pharmacological mechanisms by which silymarin advances antipyretic, anti-inflammatory, antinociceptive and antihyperlipidemic effects. 展开更多

C. ambrosioides is a Congolese medicinal plant used in the treatment of several pathologies. This work was initiated to evaluate the analgesic and antipyretic effect of the aqueous extract of leaves of C. ambrosioides. Analgesic effect was evaluated by using the acetic acid-induced writhing, the Tilk Flick test as well as the pain induced by formaldehyde. The results obtained showed that the aqueous extract significantly reduces the number of abdominal writhes (p C. ambrosioides (400 and 600 mg/kg) compared to control group (saline water). This result suggests an antipyretic effect. Chemical screening revealed the presence of alkaloids, flavones and mucilage. The presence of alkaloids and flavones could explain the analgesic and antipyretic effects attributed to this aqueous extract. 展开更多

[Objectives]To investigate the antipyretic effect and action mechanism of Jinzhen Oral Liquid.[Methods]The yeast-induced fever model was used to determine the rectal temperature of rats at 6,8,and 10 h after yeast injection.The contents of IL-6 and TNF-αin the rat serum and the contents of 5-HT and NE in the hypothalamus were detected by radioimmunoassay;the model of yeast-induced fever in rat was established by intraperitoneal injection of lipopolysaccharide(LPS),rectal temperature of the rats was determined,the contents of TNF-αand IL-1βin serum,cyclic adenosine monophosphate(cAMP)and prostaglandin E2(PGE2)in hypothalamus were detected by radioimmunoassay.[Results]After the intervention of Jinzhen Oral Liquid,the body temperature of rats in the yeast-induced fever model was significantly reduced,the IL-6 and TNF-αcontents in serum were significantly reduced,the 5-HT content in the hypothalamus was significantly reduced,while the NE content was significantly increased;after 2 h of intraperitoneal injection of LPS,the body temperature of the model rats increased significantly;after the intervention of Jinzhen Oral Liquid,the increase in rectal temperature of LPS-induced fever model rats decreased,and the TNF-αand IL-1βcontents in serum and cAMP and PGE2 contents in hypothalamus of model rats were significantly decreased.[Conclusions]Jinzhen Oral Liquid has a significant antipyretic effect,and its action mechanism may be related to reducing the inflammatory factors in the serum,thereby inhibiting the generation of pyrogenic media in the hypothalamus. 展开更多

The effects of isatin (2,3-dioxo-indole) and isatin analogues (5-methylisatin, 6-hydroxyisatin, 7-ethylisatin, N-acety- lisatin) were tested on prostaglandin E2 (PGE2)-induced fever in mice and rats. Two modes of administration were tested. Isatin or an analogue was injected simultaneously with PGE2 and the development of fever was tested, or the test compound was given 30 min following PGE2 administration and the effects on the already existing fever were measured, in mice and in rats. Isatin in a dose of 3.12 mg/kg ip was found to block the development of PGE2-induced fever in mice, while in a dose of 12.5 mg/kg ip it attenuated the existing fever. In rats isatin in a dose of 12.5 mg/kg ip blocked fever initiation, and at 25.0 mg/kg ip attenuated existing PGE2-induced fever. In mice, 5-methylisatin in a dose of 0.21 mg/kg ip blocked the initiation of fever, and at 6.72 mg/kg ip attenuated the existing fever. In rats in a dose of 3.36 mg/kg ip it blocked the development of fever, and at 13.44 mg/kg ip attenuated existing PGE2-induced fever. In mice 5,6-dimetylisatin in a dose of 0.02 mg/kg ip both blocked fever initiation and attenuated the existing fever in mice, in rats in a dose of 0.42 mg/kg ip it blocked the initiation of fever, and at 0.21 mg/kg ip attenuated the existing PGE2-induced fever. In mice 6-hydroxyisatin in a dose of 5.2 mg/kg blocked the development of fever, and at 10.4 mg/kg attenuated the existing fever. In rats in a dose of 10.40 mg/kg ip it blocked fever development and also attenuated the existing fever. In mice, 7-ethylisatin in a dose of 0.02 mg/kg ip both blocked fever initiation and also attenuated the existing fever. In rats, a dose of 0.11 mg/kg both blocked fever initiation and also attenuated the existing fever. In mice, N-acethylisatin in the dose of 0.005 mg/kg blocked fever initiation, while at 1.024 mg/kg it attenuated existing fever, in rats, in a dose of 0.096 mg/kg it blocked fever initiation, and at 0.384 mg/kg attenuated the existing fever. The results demonstrate that 7-ethyl- and N-acetylisatin are the most effective of these compounds both in blocking the development of PGE2-induced fever and also in attenuating existing the PGE 2-induced fever. 展开更多

Thais luteostoma has been utilized as a crude drug whose shell and soft tissue have been widely used for the treatment of heat syndrome in China for thousands of years. The present study was designed to investigate the antipyretic and anti-inflammatory activities of T. luteostoma. T. luteostoma was divided into shell (TLSH) and soft tissue (TLST) samples in the present study. The rat model of yeast-induced fever was used to investigate their antipyretic effects; and the rat model of hind paw edema induced by carrageenan was utilized to study their anti-inflammatory activities, and at the same time, the concentration variations of the central neurotransmitter [prostaglandin E2 (PGE2) and cyclic adenosine monophosphate (cAMP)], inflammatory mediators [tumor necrosis factor (TNFα), interleukin-1β (IL-1), interleukin-2 (IL-2) and interleukin-6 (IL-6)] and ion (Na^+ and Ca^2+) were also tested. The results showed that TLSH and TLST extracts significantly inhibited yeast-induced pyrexia in rats (P 〈 0.05), and exhibited more lasting effects as compared to aspirin, and TLSH had the better antipyretic activity than TLST, and that TLSH and TLST could significantly prevent against carrageenan induced paw edema in rats (P 〈 0.05); and markedly reduced levels of PGE2, cAMP, TNFα, IL-1β, IL-2, IL-6, and Na^+/Ca^2+. In fever model, TLST could significantly reduce the levels of PGE2 (P 〈 0.01) in rats' homogenate and TNF a (P 〈 0.05), IL-113 (P 〈 0.01) in the plasma than TLSH, whereas TLSH could reduce the content of IL-2 (P 〈 0.01) and IL-6 (P 〈 0.01) in plasma and increase the content of Ca2+ (P 〈 0.01) in plasma and homogenate more significantly than TLST. In conclusion, T. luteostoma extract has antipyretie and anti-inflammatory activities, which may be mediated through the suppression of production of PGE2, cAMP, Na^+/Ca^2+ , TNF a, IL-1β, IL-2, and IL-6. 展开更多

Objective: Mahuang-Shigao herb-pair is a famous formula composed of Ephedra and Gypsum. The herb-pair is frequently used for treating cold symptoms and bronchial asthma in the clinical practice of Chinese medicine (CM). In the present study, we evaluated evidence for the benefit of combined use of Ephedra and Gypsum by analyzing the antipyretic and anti-asthmatic activities of Ephedra-Gypsum. Methods: The antipyretic effects of Ephedra-Gypsum were evaluated in yeast-induced hyperthermia test. Thirty male Wistar rats were randomly divided into 5 groups, including control group, standard aspirin group, and 3 Ephedra- Gypsum groups of different doses (6, 12, 24 g/kg). Ephedra-Gypsum extract and asprin were administered orally 6 h after the injection of yeast solution and body temperature was measured every 1 h for 8 h. The anti- asthmatic effects of Ephedra-Gypsum were evaluated using an ovalbumin (OVA)-induced asthmatic rat model. Thirty-six male SD rats were randomly divided into 6 groups. Rats were alternately sensitized and OVA+Al(OH)3 challenged by exposure to mists of ovalbumin. Ephedra-Gypsum extracts (6, 12, 24 g/kg) or dexamethasone were administered 45 min prior to the allergen challenge for 8 days. Latent period and the weight of wet to dry ratio of lung were determined. In addition, the eosinophils in blood and white blood cell (WBC) were counted by an YZ-Hemavet Analyzer. Results: The Ephedra-Gypsum extracts at test dose (6, 12, 24 g/kg) significantly and dose-dependently attenuated yeast-induced fever in rats. The Ephedra-Gypsum extracts also prolonged the latent period, reduced OVA-induced increases in eosinophils and WBC, and decreased the wet and dry weight ratio of the lungs in the anti-asthmatic test. Conclusions: These findings indicate that the Ephedra-Gypsum extract has antipyretic and anti-asthmatic properties. Hence, the results support additional scientific evidence in prescriptions. 展开更多
