  • In the present study, the alcoholic extract of Terminalia arjuna (TA) and Arjunolic acid (AA) were studied fur its anti-asthmatic and anaphylactic activity. Treatment with TA (250 & 500 mg/kg) and AA (50 & 100 mg/kg) has shown significant protection against mast cell disruption in rats induced by compound 48/80. TA and AA also protected the guinea pig against histamine as well as acetylcholine induced bronchospasm. Both TA & AA exhibited better protection against histamine release than against acetylcholine release. Anti-asthmatic and anaphylactic activity may be possibly due to membrane stabilizing potential and inhibition of antigen induced histamine and acetylcholine release.

  • Objectives: To investigate the anti-inflammatory, analgesic, anti-pyretic and anti-histamine activities of 20 herbal medicines to test their efficacy in common cold treatment. Methods: For all experiments, the herbal medicines were extracted with 80% ethanol and freeze-dried. To determine the anti-oxidative properties, we tested DPPH-free radical-scavenging activity and xanthine oxidase inhibitory activity. To determine anti-inflammatory and analgesic potential, we investigated acetic acid-induced vascular permeability and writhing test in ICR mice. For anti-pyretic activities, an LPS-induced pyrexia study was conducted in rabbits. To evaluate the anti-histamine activity, we examined compound 48/80-induced systemic anaphylaxis in ICR mice and the release of β-hexosaminidase on rat basophilic leukemia (RBL-2H3) cells. Results: Ephedrae herba, Forsythiae fructus, Cinnamomi ramulus, and Cimicifugae rhizome showed potent free-radical scavenging activities. Gentianae macrophyllae radix inhibited acetic acid-induced vascular permeability. Schizonepetae spica and Cimicifugae rhizome inhibited acetic acid. Cinnamomi ramulus and Angelicae decursivae radix inhibited LPS-induced pyrexia. Angeliace dahuricae radix and Asari radix inhibited compound 48/80. Scutellariae radix, Cinnamomi ramulus, Ephedrae herba, and Zingiberis rhizoma crudus potently inhibited the release of β-hexosaminidase. Conclusions: We examined the anti-inflammatory, analgesic, anti-pyretic and anti-histamine activities of 20 herbal medicines;We examined the anti-inflammatory, analgesic, anti-pyretic and anti-histamine activities of 20 herbal medicines Codonopsis pilosulae radix, Zingiberis rhizoma crudus, and Cinnamomi ramulus showed novel efficacy. These results suggest that some of herbal medicines may be very effective in treating common cold.

  • The ethanolic extract of some medicinal plants having anti-asthmatic activity such as Solanum xanthocarpum, Curcuma longa, Glycyrrhiza glabra, Piper longum, A. vasica, A. lebbeck, and Tinospora cordifolia was evaluated for antihistaminic and anti-cataleptic activity. The aqueous solution of ethanolic extract of S. xanthocarpum and G. glabra potentiated histamine-induced tracheal chain contractions. Whereas, C. longa, P. longum, and T. cordifolia, and A. lebbeck were without any significant effect on histamine. Only A. vasica inhibited histamine-induced tracheal chain contraction. G. glabra per se produced contraction of the tracheal chain, which was blocked by pretreatment with atropine. Single dose of S. xanthocarpum potentiated clonidine-induced catalepsy but on repeated doses (once in a day for 3 days) inhibited catalepsy. Pretreatment with ethanolic extract of C. longa, P. longum, T. cordifolia inhibited catalepsy whereas G. glabra and A. lebbeck significantly potentiated clonidine-induced catalepsy. None of the extracts inhibited haloperidol-induced catalepsy. Thus the extracts having antihistaminic activity or mast cell stabilizing activity inhibited clonidineinduced catalepsy.

  • Objectives : In this study, we investigated the effect of KOB, a polyherbal medicine for allergic rhinitis and its main herb, Astragali Radix on allergic responses in ovalbumin (OVA)-induced Allergic rhinitis(AR) mice. Methods : Sprague Dawley (SD)-rats were orally administrated with KOB (500 mg/kg), Astragali Radix water extract (ARW, 100 mg/kg) or anti-histamine drug, dosodium cromoglycate (50 mg/kg) as a reference drug, and then intraperitoneally injected with compound 48/80 (8 mg/kg). Rats were measured the mortality and serum levels of histamine. BALB/c mice were orally administrated with KOB (500 mg/kg), ARW (100 mg/kg) or anti-histamine drug, Ketotifen (10 mg/kg) as a reference drug, followed by sensitization and challenge of OVA. Mice were measured the serum levels of histamine and IgE, and observed histopathological changes of nasa mucosa H&E staining. Results : KOB and ARW significantly decreased the mortality and the serum levels of histamine in compound 48/80-induced anaphylatic rats. KOB and ARW also decreased the serum levels of histamine and IgE in OVA-induced AR mice, and inhibited histopathological changes of nasal mucosa with inflammation and the eosinophils infilteration. Conclusions : These data suggest that KOB has a strong anti-allergic effect through the inhibitory property of Astragali Radix, the main component of KOB against allergic responses in allergic rhinitis.

  • Flavonoids are the large class of plant-derived polyphenolic compounds with a broad spectrum of biological actions including anti-inflammatory, anti-allergic and anti-asthmatic activities. It has been reported that quercetin and some other flavonoids inhibit the histamine release from mast cells. Disodium cromoglycate, a kind of biflavonoid, have been used as a anti-asthmatic agent. Therefore, the following study was undertaken to characterize tile structure-activity relationships of flavonoids in the inhibition of histamine release, from IgE-sensitized mast cells. Flavonoid acetate were synthesized by addition of acetic anhydride to the flavonoids dissolved in pyridine. According In the Mota method, IgE-rich serum was made in rats sensitized with Pertussis vaccine and ovalbumin. Rat abdominal mast cells were harvested and purified over tile discontineous Percoll gradients, Mast cells were preincubated in RPMI with IgE-rich serum and further incubated with flavonoids. Histamine contents released from mast cells were determined fluorospectrophotometrically after stimulation with ovalbumin. (omitted)

  • Achyranthes japonica Nakai (AJN) water extract has a variety of physiological properties, including anti-diabetic, anti-cancer, anti-inflammatory, anti-microbial, and anti-oxidative activities. In the present study, the inhibitory effects of AJN extract were investigated in high affinity immunoglobulin E receptor ($Fc{\varepsilon}RI$)-mediated KU812F cells activation. AJN extract showed suppressive effects on histamine release and intracellular calcium [$Ca^{2+}$]i elevation from anti$Fc{\varepsilon}RI$ antibody (CRA-1)-stimulated cells in a dose-dependent manner. Flow cytometric analysis showed that AJN extract treatment caused a dose-dependent decrease in the cell surface $Fc{\varepsilon}RI$ expression and the binding between the cell surface $Fc{\varepsilon}RI$ and the IgE antibody. Moreover, reverse transcription-polymerase chain reaction analysis showed that levels of the mRNA for the $Fc{\varepsilon}RI$ ${\alpha}$ chain was decreased by treatment with AJN extract. These results indicate that AJN extract may exert anti-allergic effects via the inhibition of calcium influx and histamine release, which occurs as a result from the downregulation of the binding of IgE antibody to cell surface $Fc{\varepsilon}RI$. This mechanism may occur through $Fc{\varepsilon}RI$ expression inhibition.

  • The role of $G{\alpha}12\;and\;G{\alpha}13$ in modulating the IgE receptor-mediated histamine secretion in the streptolysin-o-permeabilized human cultured mast cell was investigated. The expression of $G{\alpha}12\;and\;G{\alpha}13$ proteins were regulated during human cultured mast cell differentiation, and a significant correlation was observed between the levels of expression of $G{\alpha}12\;and\;G{\alpha}13$ proteins and IgE receptor-mediated histamine secretion capability in human cultured mast cells. Antibodies against $G{\alpha}12\;and\;G{\alpha}13$ effectively inhibited the IgE receptor-induced histamine release, and the concentration of anti-$G{\alpha}12$ antibody used to inhibit histamine secretion was shown to also inhibit the IgE receptor-mediated elevation of intracellular $Ca^2+$. Therefore, the results suggest that $G{\alpha}12\;and\;G{\alpha}13$ play roles in modulating IgE receptor-activated $Ca^2+$ influx, thereby regulating histamine release in cultured human mast cells. This is the first report to show that $G{\alpha}12\;and\;G{\alpha}13$ are involved in the regulation of $Ca^2+$ mediated exocytosis in human cultured mast cells.

  • Experimental studies were conducted to investigate for the effect of Tongkyu-tang on analgesic, antipyretic, sedative, anti-inflammatory, isolated ileum and anti-histamine actions. Tongkyu-Tang was composed of sixteen crude drugs including Astragali Radix, which has been used for the treatment of common cold, headache, rhinitis, nasal obstruction, rhincospasm, etc. The following results have been obtained; analgesic and antipyretic actions were obtained. Prolonged action against the hypnotic duration of pentobarbital were significantly noted in mice. Anti-inflammatory effects in the paw edema induced by 1% carrageenin and 1% dextran were significantly shown in rats. Spontaneous motilities of isolated ileum of mice were strongly suppressed, and contractions of isolated ileum of mice and guinea-pigs induced by acetylcholine chloride, barium chloride and histamine were remarkably inhibited. Antihistamine actions were noted. Considering the above experimental results, it is suggested that effects of Tongkyu-tang based on the Oriental Medical References were similarly consistent with the actual experimental results.

  • Anti-allergic action of each water extracts of some crude drugs was investigated in mice and rats. The activity of hyaluronidase which was used in the screening test of anti-allergic action was inhibited significantly by Amomi Semen, Asiasari Radix, Cimicifugae Rhizoma, Cinnamomi Ramulus, Glycyrrhizae Radix and Scutellariae Radix. The 48-hour homologous passive cutaneous anaphylaxis(48-hr PCA) in mouse ear was inhibited significantly by intraperitoneal(i.p.) injection of Amomi Semen, Cimicifugae Rhizoma, and ketotifen, a comparative drug of an anti-allergic action. The increase of vascular permeability induced by histamine or serotonin was inhibited significantly by i.p. injection of Amomi Semen, Cimicifugae Rhizoma, Cinnamomi Ramulus and ketotifen. In rat dorsal skin, the increase of vascular permeability which was induced by histamine, serotonin or compound 48/80 was inhibited significantly by i.p. injection of Amomi Semen, Asiasari Radix, Cimicifugae Rhizoma, Scutellariae Radix and ketotifen. Armeniacae Semen and Liriopis Tuber which had not inhibited hyaluronidase activity did not inhibit 48-hr PCA and the increase of histamine, serotonin or compound 48/80-induced vascular permeability in mice and rats. These results suggest that each water extract of Amomi Semen and Cimicifugae Rhizoma has anti-allergic action.

  • The effect of aqueous extract of Stachys riederi var. japonica Miq. (Labiatae) (SRAE) on the immediate-type allergic reactions was investigated. SRAE was found to exhibit a inhibitory activity on the compound 48/80-induced systemic anaphylaxis in mice. SRAE inhibited the plasma histamine release induced by compound 48/80 in mice. In addition, SRAE also inhibited the passive cutaneous anaphylaxis reaction induced by IgE/anti-IgE in mice. The effect of SRAE on the histamine release from rat peritoneal mast cells (RPMC) was studied. SRAE inhibited the histamine release induced by compound 48/80 in RPMC. To clarify the mechanism of these inhibiting reactions, we investigated the effects of SRAE on cyclic AMP (cAMP). The level of cAMP in human leukemia cell line, HMC-1, when SRAE (1 mg/ml) was added, significantly increased compared with that of basal cells. These results indicate that SRAE may be beneficial in the treatment of immediate-type allergic reaction.
