Adenosine deaminase inhibitor was extracted from culture broth of Streptomyces sp. strain V-8 with ethylacetate. The ethylacetate extract showed the characteristic UV absorption spectrum of actinomycins at 440-450 nm. The ethylacetate extract was compared with respect to inhibitory behavior against adenosine deaminase from calf intestinal mucosa with actinomycin D, -C complex and actinomycin V. The Ki values for actnomycin D, -C complex, and actinomycin V against adenosine deaminase were determined to be 9.9 $\times$ 10$^{-6}$ M, 9.6 $\times$ 10$^{-6}$ M and 9.3 $\times$ 10$^{-6}$ M, respectively. The Ki value for the ethylacetate extract of culture broth against adenosine deaminase was determined to be 5.7 $\times$ 10$^{-6}$ M. The kinetic parameters of actinomycin D, -C complex, -V and ethylacetate extract of culture broth for adenosine deaminase were as follows:I$_{50}$ = 1.5 $\times$ 10$^{-5}$ M (actinomycin D), 2.7 $\times$ 10$^{-5}$ M (actinomycin C complex), 3.5 $\times$ 10$^{-5}$ M (actinomycin V), 8.9 $\times$ 10$^{-6}$ M (ethylacetate extract of culture broth). The adenosine deaminase was inhibited noncompetitively by ethylacetate extract of culture broth as well as by actinomycin D, -C complex and actinomycin V.

Platycodon grandiflorum and Glycyrrhiza uralensis contain several bioactive compounds, such as saponin, oleanolic acid, and flavone. P. grandiflorum and G. uralensis have traditionally been used to treat disorders related to blood pressure, diabetes, and counteracting poison, and they have antinociceptive and antiinflammatory properties. However, the validity of complex saponin's vasodilatory effect has not been scientifically investigated. Therefore, this study explores the vasodilatory effect of complex saponin extracted from P. grandiflorum and G. uralensis mixture extract on rabbit carotid arteries. To this end, arterial rings with intact or damaged endothelium were used in an organ bath experiment and contracted by endothelin. Complex saponins, the major active constituents of P. grandiflorum and G. uralensis mixture extract, exhibited a moderate vasodilatory effect on the rabbit's basilar arteries. Therefore, treatment with complex saponin extracted from P. grandiflorum and G. uralensis mixture extract may selectively accelerate cerebral blood flow through basilar arterial dilation. Overall, the findings suggest that the extracted complex saponins can serve as vasodilator sources.

Objectives : This study was performed to investigate the efficacy and safety of the Mulberry Extract Complex in a placebo-controlled randomized clinical trial and animal study on degenerative arthritis. Methods : Animal study: Mulberry Extract Complex is composed of extracts of mulberry (Morus alba L.) fruit, mulberry leaves and black beans (Glycine max (L.) Merr.). To evaluate the serum level of interleukin-2, interferon-$\gamma$, and prostaglandin E2, an animal model of degenerative arthritis induced by monosodium iodoacetate was employed. Clinical study: The efficacy index (VAS, K-WOMAC) was compared among patients with symptoms of degenerative arthritis before and after Mulberry Extract Complex ingestion as well as the one in groups. Evaluations of the improvement by the subjects and by doctor assessment were also performed. Results : Animal study: Mulberry Extract Complex reduced the serum level of interferon-$\gamma$ and prostaglandin E2 in an animal model with degenerative arthritis. Clinical study: The VAS change showed statistical significance in the experimental groups after 4 weeks (PP set) and 8 weeks (ITT set) of ingestion. When the K-WOMAC was analyzed using a modified ITT set to determine the effectiveness, statistically significant results were obtained in the fields of pain & symptom within the Mulberry Extract Complex group as well as between the Mulberry Extract Complex and placebo groups after 8 weeks of ingestion. Results from the improvement evaluation by subjects and the assessment of improvement by doctors showed statistical significance in the experimental groups (PP set) after 8 weeks. Conclusions : Mulberry Extract Complex could be useful for the improvement of various symptoms of degenerative arthritis based on its anti-inflammatory activity and its reduction of VAS and K-WOMAC pain scores.

The incidence of canine cognitive dysfunction syndrome (CCDS), a prominent geriatric disease, is increasing because of the extended lifespan of companion animals. Various complementary therapies have been proposed for the management of CCDS. This study evaluated the clinical efficacy of the Brain Six Complex Extract^ⓒ in dogs with cognitive dysfunction syndrome (CDS). Fifteen dogs with CDS were included, and four to five drops of Brain Six Complex Extract^ⓒ, composed of herbal extracts, were applied around the dorsal neck of all dogs twice daily for 1-3 months. Clinical efficacy was evaluated using the CCDS scale, and serum β-amyloid oligomer concentrations were measured before and after administration of the extract. The CCDS scale score significantly decreased after administration in dogs with CDS (p = 0.0313), compared to pre-administration levels. Although the serum β-amyloid oligomer concentration decreased after administration, the change was not statistically significant (p > 0.05). A notable decrease was observed between pre- and post-administration in dogs with β-amyloid levels >300 pg/mL (p = 0.0313). The laboratory results showed no remarkable adverse effects of the extract. This study suggests that Brain Six Complex Extract^ⓒ extract could be an adjunctive treatment for dogs with CDS.

The purpose of this study is to observe the effect of Cordyceps Militaris(CM) complex extract treatment on patients diagnosed with rheumatoid arthritis(RA). We reviewed medical records of 9 rheumatoid arthritis patients who visited the pain & rehabilitation center, Daejeon Korean Medicine Hospital of Daejeon University and were treated with CM complex extract from October 14, 2019 to October 14, 2020. We analyzed the records of DAS 28(Disease Activity Score 28), CDAI(Clinical Disease Activity Index), SDAI(Simplified Disease Activity Index), VAS(Visual analogue Scale), and KHAQ-D(Korean Health Assesment Questionnaire-Disability Index) before and after treatment to evaluate the effects of CM complex extract on RA. As a result, the scores of DAS 28(p<0.05), CDAI(p<0.01), SDAI(p<0.01) and VAS(p<0.01) were statistically significantly decreased, after 8 weeks of taking CM complex extract in RA patients. In conclusion, CM complex extract treatment may have potential effects of reducing disease activity and pain and improving quality of life in patients diagnosed with RA.

The present study aimed to evaluate the effects of radiation mutant Perilla frutescens var. crispa and Atractylodes macrocephala Koidzumi complex extract(Perilla frutescens var. crispa complex extract) on the mediators related to degenerative arthritis in a monosodium iodoacetate-induced rat model of degenerative arthritis. Perilla frutescens var. crispa complex extract was administered orally at doses of 25, 50 or 100 mg/kg/day for 2 weeks before direct injection of monosodium iodoacetate (3 mg/50 µl of 0.9% saline) into the intra-articular space of the rats' right knees. The rats subsequently received the same doses of oral Perilla frutescens var. crispa complex extract for another 4 weeks. It was evaluated that the treatment effects based on serum bio-markers, and morphological and histopathological analysis of the knee joints. Compared with those in negative control rats, the Perilla frutescens var. crispa complex extract treatments significantly reduced the serum levels of inflammation, bone metabolism markers (i.e., TNF-α, MMP-3, COX-2, PGE₂, COMP, and Aggrecan). Otherwise, it was significantly increased the production of CTX-2 in cartilage absorption mediators. In addition, the Perilla frutescens var. crispa complex extract treatments effectively preserved the knee cartilage and synovial membrane. As a result, it indicates that the Perilla frutescens var. crispa complex extract improved degenerative arthritis symptoms. Thus, the Perilla frutescens var. crispa complex can be used in food material for the management of degenerative arthritis.

Complex regional pain syndrome type 1(CRPS 1) is a neuropathic pain disorder that accompanies severe pain and motor deficit as well as changes in the skin in the extremities. The pathophysiology of CRPS 1 is still not exactly elucidated. However, the general consensus of involvement of inflammatory mediators in the development of CRPS 1 is amply made. On the basis that placental extract successfully inhibited the production of inflammatory cytokines and mediators in several experimental models, we have tried a long-term weekly injection of placental extract into acupuncture points to a CRPS 1 patient suffering pain and immobilization of shoulder joint. The results say that placental extract effectively resolved pain, restored skin color and improved immobilization of shoulder joint in the CRPS 1 patient.
