N'ime akwụkwọ nke Arthritis Research & Therapy , Alves na ọdịnala ha [ 1]汇报了一项有趣的临床前研究,表明将红外光应用于大鼠膝关节在骨关节炎动物模型中对关节炎症有显著益处。在美国,每两个人中就有一个在其一生中的某个时候会经历某种形式的骨关节炎,而在75岁以上的人群中,其发病率为80% [ 2]. Aka nwere ike ịgbachi ndụ (acetaminophen), mmiri nchekwa na-eme mmiri nnukwu (NSAIDs) (ibuprofen na diclofenac), na COX2 inhibitors (Celebrex, Pfizer Inc., New York, NY, USA), ma obere ha nwere ọgwụ iche n'ezie, site gastrointestinal bleeding na-eme heart attack n'aka COX2 inhibitors [ 3]. Low-level laser (light) therapy (LLLT) bụ nweta nwere ike na-eme na-agba n'ime ọzọr ọnwa ndụ nke akwụkwọ gara aga, nke ịkpamgoshi nke ndụ na-eme healing, na ịchọma nke mara ọnwa ndụ nke agha ọkara ma na infarction [ 4]. Akuku red ma near-infrared nwere ike na-eme n'akpa cytochrome c na-eme mmiri nnukwu (unit IV nke mitochondrial respiratory chain), na-akwụcha ndụ mitochondria na ATP production na na-eme signaling pathways maka reactive oxygen species, nitric oxide, na cyclic AMP, na-akwụcha nke nwere ike na-eme na-eme several transcription factors [ 5]. Nkārịrị ọdịnaya nke mmiri na-akwado ihe iche-iche anti-inflammatory effects of LLLT na-eme ka ọnwa ndụ ikike (neutrophils, macrophages, lymphocytes, na mast cells) akpụra n'ime ọdịnaya na-enye na-eme ka ọnwa ndụ ikike nke iche-iche inflammatory cytokines, mara ILs na TNF-α. Ntụntụ ntụ na-eme ka ọ bụrụ na-aka biphasic dose response a na-eji LLLT, na ọ bụrụ na ime mkpa ọnụrụ ma ọ bụ na-eme mkpa ọnụrụ (power density) bụgwara eziokwu, na-enye aka ndị mmiri ndụ na-eme ka ndị ite mkpa ọnụrụ LLLT [ 6]. LLLT na-eji ihe clinical n'osteooarthritis nke otu ọzọ maka ọ bụrụ na-anaghị eweta na-agha. Mma Cochrane review [ 7] nwere ihe ezu na-akwado, anaobi akwukwo dịka biara na-eche Bjordal na ọdịnala gara a ka 'akwukwo Cochrane bụ nnọkọ na-anachịta. Anaobi na-abụghị mmiri na-inye ndị na-eme egwuregwu, na-anachịta na-enweghị ndị na-eme follow-up, na anali subgroup na-ekwu ihe nke akwukwo atụgharịa na ejikere na-eme LLLT maka osteoarthritis' [ 8]. Ihe nwere ihe ezu na-akwado ahụ suggest na otu ndị na-adịghị mmasị kpataku nke mmalite na-anabere animal studies, clinical trials, na systematic reviews kwa LLLT maara ga-emechaa nke mmalite.
Alves na ọdịnala gara a [ 1] nwere ike ọdịnala ndị na-ekwu modelụ ka osteoarthritis maara na-enye proteolytic enzyme papain na-akwụkwa maka nkpu ikuku rat, ndị na akwụkwa cartilage gbasara, maara na-enye inflammation. Nkpu ikuku ga-eme oge abụọ mmepụta 4 J energy n'aka laser 808-nm na-agbakwuru na-abịa na na-akpata na nkpu ikuku, na-eme na-abịa maka 50 ma 100 mW, na ndị rat ga-eje maka 24 ozi. Ntụntụ nwere ike ọdịnala ndị na-eme reduction n'ime inflammatory cells n'ume fluid n'asusu synovial washing na-abịa maka mmepụta power, maara na-enye reduction nke macrophages na-power level 50-mW. Reductions n'ime IL-1β na IL-6 mRNA were found, na 50 mW bụrụ na-eme better than 100 mW, maara na-enye bigger reduction nke TNF-α n'ime 100 mW. Ntụntụ na-eme hypothesis na oge illumination twice longer needed to deliver same energy at half the power bụrụ na-eme responsible for better effect of 50-mW laser application, na ihe bụrụ na-agbaa with study nke otu ha na-egosi zymosan-induced arthritis n'ikuku rat [ 9] na-achọ bụụ kwụsịrị ndị iche ihe nwere ike ọgwụ abụghị. Nkērịtịta ndị ya [ 10] ga-ezi okwu na LLLT n'aka njemaa na-abụghị modelu, zụtara angiogenesis na akwụkwọ ha maka squamous epithelium ma ọ bụrụ na ọnwa fibrosis n'aka n'okpuru. Ihe ha na-eme mkpisi ọzọ maka nsọ nkwerẹe LLLT (nweta laser near-infrared e nyere ihe nwere ike ọgwụ n'okpuru maka aka) kama ọgwụ mmadụ maka osteoarthritis. Ma ọ bụrụ, ka anya nwere ike na nkọwa na-ekwu ọzọ na modelu ụlọ mmeghị, ma ọ bụrụ na ọ bụ clinical study n'ụlọ ọha mmadụ, na nkwerẹe ọzọ na-akwado site si ihe mere LLLT n'aka osteoarthritis. N'afọ na ihe mere anti-inflammatory, LLLT ma na-eme mkpisi ọzọ maka ike ya nwere ike ịnanya ụmụ nke ọchịchị ụkpụrụ na-agba endogenous opioid receptors [ 11].
