In order to investigate the immunomodulational effects of Lonicerae Caulis et Folium, the author measured cytokines production(IL-10, IL-12(P35), IL12(P40), $IFN-{\gamma}$) in mice splenocytes. The results were obtained as follows : 1. The water extract of Lonicerae Caulis et Folium significantly enhanced the gene expression of IL-12(P35), IL-12(P40), but reduced the gene expression of IL-10, $IFN-{\gamma}$. 2. In water fraction and ethyl acetate fraction, the gene expression of IL-12(P35), $IFN-{\gamma}$ was significantly increased and that of IL-12(P40), IL-10 was decreased. The above results demonstrate that Lonicerae Caulis et Folium has enhancing immune activity by upregulation of these cytokines. Therefore, if we make the relationship between these cytokines(IL-10, IL-12, $IFN-{\gamma}$) besides IL-1, IL-4, IL-6, $TNF-{\alpha}$, IL-8, $TGF-{\beta}$ and so on which concerned the immunopotentiation, the immunopotentiational mechanism of Lonicerae Caulis et Folium will be shown clearly.

Lonicerae Folium et Caulis, the folium and stem of Lonicera japonica Thunb., has been used as diuretic, stomachic, antipyretic, analgesic and anti-inflammatory agent in Korea. We isolated a main iridoid, loganin which has some important biological effects from the folium and stem of this plant. Generally, it is known that iridoid compounds have variable contents by the collecting time and a part of plant. The content of main compound is important to evaluate its quality. In order to evaluate the quality of Lonicerae Folium et Caulis, the method of quantitative determination of loganin as a reference standard compound has been developed. (omitted)

HAE-06 extract is a mixture of four medicinal plants, namely Lonicerae Folium et Caulis (Lonicera japonica), Scutellariae Radix (Scutellaria baicalensis), Adenophorae Radix (Adenophora triphylla var. japonica), and Polygonati Oddorati Rhizoma (Polygonatum odoratum var. pluriflorum). The HAE-06 extract demonstrated a concentration-dependent relaxing effect and enhanced cAMP production in bronchial smooth muscle that had been stimulated to contract with acetylcholine. Using a blocker, it was confirmed that the effect was through the β2-adrenergic receptor/cAMP/PKA pathway. In addition, it is thought that the HAE-06 extract has a bronchial smooth muscle relaxation effect by reducing the inflow of Ca²⁺ through the K⁺ and Ca²⁺ channels present in the sarcoplasmic membrane. If research continues in the future, it is believed that it will be possible to use it as a material for pharmaceuticals and functional foods.

HAE series (HAE 01 - 06), are the mixtures of medicinal plants; Lonicerae Folium et Caulis (Lonicera japonica), Scutellariae Radix (Scutellaria baicalensis), Adenophorae Radix (Adenophora triphylla var. japonica), Polygonati Oddorati Rhizoma (Polygonatum odoratum var. pluriflorum), Platycodi Radix (Platycodon grandiflorum), Liriopis seu Ophiopogonis Tuber (Liriope platyphylla). HAE 06 showed the significant antitussive effect in HAE series. HAE 04, 05, and 06 increased the effect of expectorant measured by secretion of phenol red in rats. All tested HAE series were observed to have the anti-oxidant activity determined by the scavenging activity. HAE 01, 03 and 06 were significantly reduced the production of nitric oxide (NO) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) increased by LPS. HAE 06 was selected based on the results and done further experiments. HAE 06 inhibited the number of coughing induced by citric acid in dose dependent manner. HAE 06 effectively increased the effect of expectorant. HAE 06 exhibited anti-inflammatory effects by inhibiting the production of NO and TNF-${\alpha}$. In addition, HAE 06 significantly suppressed inducible Cyclooxygenase-2 (COX-2). Especially HAE 06 has the highest effect in alleviating the respiratory symptoms. Moreover, the enhancement antioxidant activity and reduction inflammation partly were attributed to it. HAE 06 may become the promising candidate for the treatment of respiratory symptom in the future.

This study was carried out to investigate the residual sulfur dioxide residues ($SO_2$) in commercial medicinal herbs in Korea in 2013. Among a total of 116 samples of 11 different kinds of herbs, 71 samples (11 Kinds) were domestic, and 45 samples (10 Kinds) were imported. The residual contents of $SO_2$ in the samples were determinated by a modified Monier-Williams method. Of the 116 samples, 6 samples (5.2%, 4 Kinds) failed to meet the regulations for sulfur dioxide residues of KFDA in medicinal herbs. Among 6 unsuitable samples, 1 samples (1.4%) were domestic, and 5 samples (11.1%, 3 Kinds) were imported. The highest amount of sulfur dioxide residues was 1546.3 mg/kg (Lycii Fructus) in the domestic samples. Regardless of region, $SO_2$ contents were not found at Anemarrhenae Rhizoma, Citri Unshius Pericarpium, Eucommiae Cortex, Forsythiae Fructus, Gardeniae Fructus, Leonuri Herba and Lonicerae Folium et caulis. These data will be used as a basic data for the future legislation on the regulation and control of sulfur dioxide of herbal medicines.
