About

The effect of Crocina on the production of IL-4, IL-1 bet, IL-17, IL-10 and TGF-beta: The effect of crocina on gene expression of transcription factors T-bet, GATA-3. FOXP3, ROR-γt,; The effect of helper T cells type one and two, regulatory T cells and T helper type 17 cells; the effect of crocina on the reduction of pain and joint inflammation. Design: Randomized, Double-blind and Placebo controlled; Study population: Patients with Osteoarthritis; Volume: 40 persons; Method: Osteoarthritis patients will be divided into two groups according to age and sex; Crocina tablets will be prescribed to the first group a tablet 15 mg daily along with conventional Medicines; Placebo tablets will be prescribed to the second group along with the conventional medicines; Blood sampling of patients will be done before drug administering and four months after treatment.

Time: 4 months; Main outcome Measures: Osteoarthritis, Pain, Inflammation, Crocina, IL-4, IL-1 beta, IL-17, IL-10, TGF- beta, Cell surface protein CD127, The expression of T-bet, GATA-3, FOXP3, ROR-γt and the number of Th1, Th2, T-regulatory and Th17.

Full description

The effect of crocina on the production of IL-4, IL-1β, IL-17, IL-10 and TGF-β by ELISA assay;The effect of crocina on gene expression of transcription factors T-bet, GATA3, FOXP3, ROR-γt by Real-Time PCR; The effect of crocina on number of helper T cells type one and two, regulatory T cells and T helper type 17 cells by Flow Cytometry analysis; The effect of crocina on the reduction of pain and joint inflammation by WOMAC osteoarthritis index, vas score pain and CRP, ESR diagnostic tests . Design: Randomized, Double-blind and Placebo controlled; Study population: Patients with Osteoarthritis; Volume: 40 persons; Method: Osteoarthritis patients will be divided into two groups according to age and sex; Crocina tablets will be prescribed to the first group a tablet 15 mg daily along with the conventional medicines. 30 pills of crocina or placebo in cans quite similar and be encoded with Excel Software will be given to the patients completely random; The distributor and the patient will have no knowledge of the contents of the cans; After the end of each month, the patients will receive similar to their previous code. Blood sampling of patients will be done before drug administering and four months after the treatment. Major Inclusion Criteria: Osteoarthritis patients with age 40 to 75 years; The severity of joint damage between grade 2 and 3; Patients without history of injury; Patients with the Body Mass Index (BMI) less than 30. Major Exclusion Criteria: Osteoarthritis patients with age less than 40 and more than 75; The severity of joint damage in the grade one and four; Patients with history of injury and body mass index 30 or more. Intervention: Treatment with prescription of drug at dose of 15 mg daily crocin in the study group and placebo in the control group; Time: 4 months. Main Outcome Measures: Osteoarthritis, Pain, Inflammation, Crocin, IL-4, IL-1 beta, IL-17, IL-10, TGF-beta, Cell surface CD127, The expression of T-bet; GATA3; FOXP3; RORgt and the number of Th1, Th2, T-regulatory and Th17
