Problems solved by technology

[0015] 4. Corticosteroids: These drugs are very effective in treating rheumatoid arthritis, but they can have many side effects
Although the drug has the effect of reducing pain, stiffness and inflammation, long-term use may cause insomnia, tinnitus, edema, gastric ulcer, gastric bleeding, gastric perforation (gastrobrosia), skin sensitivity, proteinuria, diabetes, high blood pressure, bone Side effects such as osteoporosis, cataract, and decreased resistance to infection. At the same time, regular blood biochemical and serum examinations are required during the treatment to ensure the effectiveness of the treatment and avoid the occurrence of the above-mentioned side effects
[0018] To date, there is no drug that can effectively treat or relieve rheumatoid arthritis without producing unwanted side effects

Embodiment 1

[0072] Example 1. Preliminary screening of Lactobacillus isolates with anti-inflammatory activity

[0073] Experimental materials and methods:

[0074] A. Source and preparation of test strains:

[0075] The applicant obtained the gastrointestinal tract specimens of many healthy adults through the Affiliated Hospital of China Medical University (Taichung City) in February 1991, and isolated more than 400 strains of Lactobacillus isolates from these specimens. In order to find probiotics with the potential to be used in the treatment of rheumatoid arthritis, applicants analyzed the anti-inflammatory activity of these Lactobacillus isolates and used IL-10 as a screening marker.

[0076] Each test strain was inoculated into Lactobacillus Bacto MRS broth medium (DIFCO, Cat. No. 0881), and then anaerobically cultured at 37° C. for 12 to 18 hours. The resulting bacterial culture was centrifuged at 4,000 rpm for 15 minutes, the supernatant was discarded, and the precipitate was was...

Embodiment 2

[0093] Example 2. Evaluation of Lactobacillus isolates stimulating the ability of human PBMC to secrete IL-10 and IFN-γ

[0094] Experimental materials and methods:

[0095] A. Preparation of human peripheral blood mononuclear cells:

[0096] Take human white blood cell concentrate (Tainan Blood Donation Center) and Ficoll-Paque that have passed the inspection and are used for experiments TM PLUS (17-1441-03, Amersham Biosciences) was used for density gradient centrifugation (720 g x 20 min at 4° C.) at a volume ratio of 1:1. Afterwards, the erythrocytes were removed, and the resulting human PBMCs were adjusted to a cell concentration of 4×10 in RPMI 1640 medium containing 10% FBS. 6 cells / mL for later use.

[0097] B. Evaluation of Lactobacillus isolates stimulating human PBMC to secrete IL-10:

[0098] The ability of Lactobacillus isolates GMNL-19, GMNL-76, GMNL-78, GMNL-89, GMNL-94, GMNL-101 and GMNL-161 to stimulate human PBMC to secrete IL-10 is basically the "experi...

Embodiment 3

[0122] Example 3. Evaluation of the therapeutic effect of Lactobacillus isolates GMNL-76 and GMNL-89 on rats with collagen-induced arthritis

[0123] Experimental materials and methods:

[0124] A. Experimental animals:

[0125] Male LEW / SsNNarl rats (6 weeks old, body weight approximately 200 to 250 g) obtained from the National Applied Research Laboratories National Laboratory Animal Center were used in the following experiments. All experimental animals were kept in an individually air-conditioned animal room with 12 hours of light and 12 hours of darkness, room temperature maintained at 25±1°C and humidity maintained at 60±5%, and water and feed were adequately supplied. Give the animals a week to acclimate to the environment, and start the experiment after the animals are stable. The handling of experimental animals and all experimental procedures are carried out in accordance with the standard regulations of the Experimental Animal Committee.

Abstract

The invention discloses two Lactobacillus isolated strains with anti-inflammatory activity and beneficial probiotic characteristics, namely lactobacillus sakei GMNL-76 and Lactobacillus reuteri GMNL-89, which are respectively preserved at the Bioresource Collection and Research Center (BCRC) of the Food Industry Research and Development Institute (FIRDI) with the preservation numbers of BCRC 910355 and BCRC 910340, and preserved at the China Center for Type Culture Collection (CCTCC) with the preservation numbers of CCTCC M 207153 and CCTCC M 207154. The two Lactobacillus isolated strains andsubculture progeny thereof can be used for preparing various food products, and drug composites used for curing and / or relieving diseases related to inflammation, such as rheumatoid arthritis.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of May 8, 2008, an application number of 200810091395.5, and an invention title of "Lactobacillus isolate with anti-inflammatory activity and its use". technical field [0002] The present invention relates to two Lactobacillus isolates having anti-inflammatory activity and beneficial probiotic properties, namely Lactobacillus sakei GMNL-76 and Lactobacillus reuteri GMNL-89, which were deposited with the Biological Resource Conservation and Research Center (BCRC) of the Food Industry Development Institute (FIRDI) under the deposit numbers BCRC 910355 and BCRC 910340, respectively, and with the deposit numbers CCTCC M 207153 and CCTCC M 207154 in China Center for Type Culture Collection (CCTCC).
