（中央社記者唐佩君新加坡14日專電）把血漿注入臉部皺紋部位，可讓肌膚回春？在新加坡，這項臨床試驗療法被官方下令中止，但不服氣的醫生表示，要帶到柬埔寨繼續進行臨床試驗。

Daily supplementation with 1 to 5 mg of folate has reduced nausea, vomiting, stomatitis and oral ulceration, elevated transaminases, and mild myelosuppression without compromising the efficacy of methotrexate.8-11 Liver fibrosis, pneumonitis, and moderate to severe myelosuppression are not mitigated by folate supplementation. Elevated homocysteine levels, common with methotrexate use and an independent risk factor for coronary artery disease, are decreased with folate supplementation.32
Folinic acid should not be given on the same days as methotrexate dosing. Unlike folinic acid, folate does not compete with methotrexate for cellular uptake. Folate is also considerably cheaper than folinic acid. For these reasons, folate supplementation is preferred by many authorities. One drawback to folate supplementation is the potential masking of vitamin B12 deficiency. Use of folate supplementation with methotrexate therapy is increasing rapidly. Methotrexate overdose is more likely in patients with declining renal function, in those who misunderstand dosing directions, or in those concomitantly exposed to a second folate antagonist, such as trimethoprim-sulfamethoxazole. Overdose should be treated promptly with folinic acid (leucovorin). Folinic acid is metabolized in vivo to tetrahydrofolate in the absence of dihydrofolate reductase, providing an alternative supply of DNA and RNA precursors. Folinic acid should be given early, preferably within the first 24 to 36 hours after overdose. Folinic acid itself has very little toxicity. Therefore, an oral dose of 10 mg/m2 should be given on first suspicion of methotrexate overdose without delay for a serum assay. Peroral or parenteral doses may be continued every 6 hours until the serum concentration of methotrexate falls to less than 10-8 M.7 Practically speaking, or when a serum assay is unavailable, this recommendation is often equivalent to 15 to 25 mg of folinic acid by mouth every 6 hours for 6 to 10 doses.

回收再利用的環保觀念，愈來愈為世人所接受，近年在醫學美容領域也開始掀起所謂自體利用風潮，討論較為熱門的莫過於自體脂肪利用、自體血液分離出PRP生長因子，以及自體幹細胞運用等。其中有助於雄性禿與圓禿者生髮，就屬以PRP生長因子刺激毛囊，提高毛髮的存活率，受到特別重視，甚至國外也有許多研究報告証實其臨床效果。
