Musculoskeletal disorders (MSDs) are medical condition mostly caused by work related occupations and working environment, affecting patients’ muscles, joints, tendons, ligaments and nerves and developing over time. A community sample of 73 females and 32 males aged 85 and over underwent a standardised examination at home. Musculoskeletal pain was reported by 57% of those interviewed. A major restriction of joint movement range was frequent in the shoulder but uncommon in other joints(1).
Osteoarthritis
Osteoarthritis (OA), a form of arthritis, is defined as a condition of as a result of aging causes of wear and tear on a joint, affecting over 25 million people in the United States in alone. University of Porto Medical School indicated that one must understand the differences in prevalence and incidence estimates of osteoarthritis (OA), according to case definition, in knee, hip and hand joints(3).
The characteristics of osteoarthritis are aching pain(5), stiffness(6), or difficulty of moving the joint or joints(7). The pain usually gets worse in change of weather, at night and in the advanced diseases, the pain can occur even at rest(8). Today management of osteoarthritis (OA) focuses on pain relief and improved physical function through pharmacological, non pharmacological, and surgical treatments(4).
The preventive Phytochemicals
1. Epigallocatechin including catechins, found abundantly in green tea, St John wort, black Tea, carob flour, Fuji apples, etc. is a phytochemical of Flavan-3-ols, in the group of Flavonoids (polyphenols)
EGCG has shown to slow the progression of OA and relieve OA-associated pain in a mouse model study of research team lead by Dr. Daniel J Leong(201).
a. Inflammatory effects
Catechins might be useful therapeutically as an anti-inflammatory modulator of dental pulpal inflammation(203), through up-regulated expressions of IL-8 in fighting against infection or PGE(2) in response to infection or inflammation(202).
b. Antiviral activities
(-)-epigallocatechin (EGC) and green tea extract (GTE) inhibited the cytopathic effect of coxsackie B3 virus, but did not inhibit the cytopathic effects of HSV-1, HSV-2, influenza A or influenza B viruses(203(204).
c. Antioxidants
Polyphenolic components extracted from green tea leaves, exhibit antioxidative effects against free radical initiated and peroxidation of human low density lipoprotein(205)(206).
2. Catechin is phytochemical of Flavan-3-ols, in the group of Flavonoids (polyphenols), found abundantly in white tea, green tea, black tea, grapes, wine, apple juice, cocoa, lentils, etc.
a. Body-weight regulation
Green tea-caffeine showed to exert its hypolipidemic and antiobesogenic effects through regulate peroxisome proliferator-activated receptors (PPARs) in the effect on lipid metabolism and obesity(207). The Ewha Womans University study also support the above result in weight reduction but through genes expression(208). It mixture improves weight maintenance, through thermogenesis, fat oxidation, and sparing fat free mass(209).
b. Antioxidant activity(210)(211)
Polyphenolic compounds (included catechins) in the berries of edible honeysuckle, including proanthocyanidins, catechins, exhibit the beneficial anti-adherence and chemo-protective activities in against a number of chronic conditions, e.g., cancer, diabetes mellitus, tumour growth or cardiovascular and neurodegenerative diseases, according to the study by Constantine the Philosopher University in Nitra(212).
c. Anti-inflammatory effect
Polymeric tannins and monomeric flavonoids, such as catechin and epicatechin found in green tea showed to exhibit anti inflammatory effects(213) through interfere with immunobiochemical pathways that are highly relevant for immunosurveillance and competing virus infections(213).
3. Theaflavin is phytochemicals of Flavan-3-ols, in the group of Flavonoids (polyphenols) found abundantly in black tea.
a. Antioxidant capacities
Theaflavin-3′-gallate (TF(2)B), a derivative of theaflavin exhibits positive antioxidant capacities on singlet oxygen(214), hydrogen peroxide(215), hydroxyl radical(216), and the hydroxyl radical induced DNA damage in vitro(214).
b. Antimicrobial activities
Plant polyphenols, including Theaflavins have exhibited anti microbial activity against several food-borne pathogenic bacteria(217) and growed in Mueller-Hinton medium(218).In the evaluation of the antimicrobial activities of seven green tea catechins and four black tea theaflavins, including (-)-gallocatechin-3-gallate, (-)-epigallocatechin-3-gallate, (-)-catechin-3-gallate, (-)-epicatechin-3-gallate, theaflavin-3, 3′-digallate, theaflavin-3′-gallate, and theaflavin-3-gallate exhibit antimicrobial activities, better than medicinal antibiotics, such as tetracycline or vancomycin, at comparable concentrations(218).
c. Anti inflammation
The major polyphenolic compounds in black tea leaves are theaflavins strongly inhibited TPA-induced edema of mouse ears, through its anti inflammatory activity(219).
4. Myricetin is a flavonol, belong to the flavonoid in Flavonoids (polyphenols), found in many grapes, berries, fruits, vegetables, herbs, as well as other plants. It has been used as antioxidant to lower cholesterol, treat certain types of cancer, etc.
a. Antioxidant and cytotoxic activity
Extracted from plants containing phenolic compound, including flavonoid-galloyl glycoside [myricetin 3-O-(2',3'4'-tri-O-galloyl)-α-l-rhamnopyranoside] exhibited high antioxidant activity(220)(221) and cytotoxic activity(222) against Hep G2 and hepatocellular carcinoma(220).
b. Antitumour and anti-inflammatory activities
On mammary tumour cells LM2, myricetin may be a promising agent in the treatment of murine breast cancer by immunomodulatory and antiproliferative activities due to its inhibitory activity to the release of NO(223). According to the study by East China Normal University, the phytochemical Myricetin also consist anti obesity and anti anti inflammatory activity(224)
5. Cyanidin is an anthocyanins (flavonals), in the group of Flavonoids (polyphenols), found abundantly in red apple and pear, bilberry, blackberry, blueberry, cherry, cranberry, peach, plum, hawthorn, etc.
a. Antioxidants
In menopausal women, intake antioxidants has shown to reduce the level of OS. Blackberries (BBs) containing mainly cyanidin 3-O-β-d-glucoside (C3G) exhibit its antioxidant effect in preventing bone loss in rat model(225). According to the joint study by Wonkwang University, Cyanidin-3-glucoside (C3G) is one of the major components of anthocyanin, a water-soluble phytochemical, may be a potential antioxidant for prevention of bone-related diseases, such as osteoporosis, rheumatoid arthritis, and periodontitis(226)
b. Anti-inflammatory Effects
According to Kyung Hee University, cyanidin-3-O-beta-D-glycoside express potent anti-inflammatory effects by regulating NF-kappaB pathway(228). Its polyphenolic-enriched red raspberry extract, containing Cyanidin-3-glucoside (C3G) one of the major component of anthocyanin decreases in the rate of degradation of both proteoglycan and type II collagen as well as inhibition of inflammation, pannus formation, cartilage damage, and bone resorption(227).
c. Obesity
Cyanidin-3-O-β-glucoside (Cy-3-g)-rich foods inhibited the onset of obesity, partly related to the activation of skeletal muscle lipoprotein lipase(LPL), and inhibition of LPL in adipose tissue(229)(230).
