Description
本發明涉及羊肚菌活性物質的製備以及其用途。具體來說,係關於以羊肚菌活性物質減緩肌肉萎縮、促進肌肉質量、肌握力及肌耐力,或製備改善肌少症之醫藥組合物的用途。
骨骼肌減少症,簡稱肌少症(Sarcopenia),是指隨著年齡增長,骨骼肌肉質量與力量流失並降低身體活動能力的一個現象。一般而言,肌肉在 30 歲以後,每年會自然流失0.5%-1%,75歲後約減少40%,到了90歲時肌肉則減少50%。在美國及部分歐洲地區的研究顯示,肌少症盛行率在60-70 歲的長者約為5-13%,80 歲以上則約為11-50%。在台灣的研究則顯示,65 歲以上的長者肌少症盛行率約為3.9-7.3%。
肌肉除了運動的功能之外,同時還有免疫和內分泌等功能,因此罹患肌少症可能造成疾病發生率提高、生活品質降低、甚至死亡,然而目前卻沒有有效治療肌少症的方法。
羊肚菌(Morchella),是世界著名的大型食用真菌,其子實體的上半部表面具不規則的皺褶,形如羊肚而得名。羊肚菌味道鮮美,營養豐富,所含的營養成份,和牛乳、魚肉相當。不僅含有豐富的蛋白質,碳水化合物外,還含有多種微量元素和19種胺基酸。該菌具有益腸胃,助消化和化痰理氣之功效,可用於治療脾胃虛弱,消化不良,痰多氣短等症。
目前尚未有羊肚菌可用來改善肌少症,或增加肌肉質量、肌握力及肌耐力之相關研究。

實施例一 羊肚菌菌絲體培養
本實施例使用之羊肚菌係來自財團法人食品工業發展研究所之生物資源研究中心(BCRC),羊肚菌菌種為美味羊肚菌(
Morchella esculenta),寄存編號為BCRC-36352。不過,本發明所用之羊肚菌並不限於美味羊肚菌,還可選自粗柄羊肚菌
(Morchella crassipes)、黑脈羊肚菌
(Morchella angusticeps)、尖頂羊肚菌
(Morchella conica)、高羊肚菌
(Morchella elata)、小羊肚菌
(Morchella deliciosa)或上述菌種之組合。在其他實施例中,亦可選用其他種類之羊肚菌,本發明並不對此限制。
(1)平板培養:將羊肚菌菌絲體接種於平板上,於15-30℃下培養1-2週(本實施例中,係於25℃下培養7天)。平板培養基的成份可包含馬鈴薯糊精培養基(Potato Dextrose Agar, PDA)、碳源及氮源,並無特別限制。
(2)燒瓶培養:刮取平板培養完成後之菌絲體接種於燒瓶中,並以15-30℃、pH 2-6及轉速110-150 rpm的條件震盪培養4-7天(本實施例中,於25℃、pH 5、轉速120 rpm之下震盪培養7天)。此震盪培養係以下表1所示之培養基進行培養。
表1 培養基配方
成分 | 本實施例使用含量 (重量%) | 較佳含量範圍(重量%) |
綜合性碳氮源 | 2 | 1-3 |
醣類 | 2 | 1-4 |
酵母抽出物 | 0.3 | 0.1-1 |
蛋白腖 | 0.3 | 0.1-1 |
無機鹽類 | 0.1 | 0.01-0.5 |
上述培養基配方中,綜合性碳氮源可選自穀類(如:麥粉)或豆類(如:黃豆粉、綠豆粉、大豆粉、肉桂粉等);醣類可為葡萄糖、果糖、麥芽糖、蔗糖等;無機鹽類可為硫酸鎂、磷酸氫二鉀、磷酸二氫鉀、硫酸鐵等。特別說明的是,表1培養基配方僅為其中一種範例,使用時成份可依需求調整,或搭配市售培養基使用,並無特別限制。
(3)發酵槽培養:將(2)中燒瓶培養的菌絲體接種於發酵槽內,以15-30 ℃、槽壓0.5-1.0 kg/cm
2、pH 2-6及攪拌速度50-150 rpm條件下,以0.1-1.5 VVM的通氣速率培養6-10天,形成一羊肚菌菌絲體發酵液(本實施例中,係在25℃、槽壓0.5 kg/cm
2、pH 5,攪拌速度80 rpm及1.0 VVM(空氣)的條件下,培養14天),即得羊肚菌菌絲體發酵液。發酵槽培養使用之培養基可與步驟(2)燒瓶培養使用之培養基相同。此羊肚菌菌絲體發酵液內即含本發明之羊肚菌菌絲體活性物質。羊肚菌菌絲體發酵液可進一步藉由冷凍乾燥步驟製備為羊肚菌菌絲體發酵液凍乾粉。於本實施例中,100 L的羊肚菌菌絲體發酵液可製得約3 kg凍乾粉。
(4)萃取物製備:使用純水或醇類作為溶劑,對(3)的凍乾粉進行萃取。
水萃物:先取羊肚菌菌絲體發酵液凍乾粉200g,加入20倍體積蒸餾水溶解,以溫度100℃加熱30分鐘,待冷卻後經冷凍乾燥法進行乾燥,得羊肚菌菌絲體水萃物。
醇萃物:將羊肚菌菌絲體發酵液凍乾粉200g加入20倍重量之乙醇,以超音波震盪1小時,離心後取上清液,將上清液經減壓濃縮得羊肚菌菌絲體發酵液醇萃物。
經由萃取步驟,可取得含較高濃度之羊肚菌活性物質。羊肚菌活性物質的態樣包含羊肚菌菌絲體發酵液(菌絲體與澄清液/上清液)、發酵液凍乾粉、水萃物、醇萃物、水萃物及醇萃物之混合物、水萃物或醇萃物凍乾粉或其他劑型。以下實施例二中,係以水及醇萃物作為羊肚菌活性物質態樣來進行肌肉萎縮現象的改善實驗;實施例三中,則將水萃取物及乙醇萃取物充分混合以獲得「萃取混合物」,作為餵食試驗之羊肚菌活性物質。一實施例中,水萃取物及乙醇萃取物的混合比例為重量比1:1。
實施例二 羊肚菌活性物質 ( 水萃物及醇萃物 ) 改善肌肉萎縮現象
目前已有實驗利用地塞米松(Dexamethasone)誘導小鼠骨骼肌細胞C2C12肌肉萎縮模式。可參照Chen-Yuan Chiu, Rong-Sen Yang, Meei-Ling Sheu, Ding-Cheng Chan, Ting-Hua Yang, Keh-Sung Tsai, Chih-Kang Chiang, Shing-Hwa Liu (2016), Advanced glycation end-products induce skeletal muscle atrophy and dysfunction in diabetic mice via a RAGE-mediated, AMPK-down-regulated,
J Pathol, 2016 Feb; 238(3):470-82此篇論文,其利用人工合成的糖皮質激素-地塞米松(Dexamethasone)使已分化的C2C12萎縮,建立肌肉萎縮的模式,透過觀察細胞型態及檢測肌肉束直徑大小,作為肌肉萎縮嚴重程度之依據。本實驗依此方法,以已分化的小鼠骨骼肌肉細胞C2C12對地塞米松進行H&E(hematoxylin and eosin)染色,評估羊肚菌菌絲體活性物質對肌肉萎縮現象的改善結果,實驗方法如下:
(1) 收集小鼠骨骼肌肉細胞C2C12細胞,調整細胞懸浮液濃度,以1x10
5- 2x10
5細胞密度植種於6孔盤內,給予細胞生長培養基(DMEM, 10% Fetal Bovine Serum);
(2) 將(1)之6孔盤置於37℃、5% CO
2培養箱培養兩天後,在顯微鏡下觀察,當細胞長至70%滿,即可加入分化培養基(DMEM, 2% Horse Serum)進行誘導,每兩天更換一次新鮮分化培養基,分化過程共七天。
(3) 在細胞分化第七天,約90%的細胞形成肌管後,加入1 µM 地塞米松及實施例一所獲得之單一劑量的羊肚菌菌絲體水萃物(10 µg/ml)或醇萃物(1 µg/ml)。將羊肚菌菌絲體萃取物溶解於二甲基亞石楓(Dimethyl sulfoxide, DMSO)中,檢測時DMSO之濃度不超過0.1%以避免其毒性影響細胞生長;對照組處理0.1% DMSO,單一濃度進行3重複,結果置於37℃、5% CO
2培養箱培養24小時,並進行後續檢測實驗;
(4) 當肌管發生萎縮,其寬度會明顯減少。利用倒立式顯微鏡,以40X 放大的視野下,每一重複取60個細胞,使用Image-Pro Plus software計算其肌管寬度可判斷肌肉萎縮的程度。
(5) 各試驗3重複,數值以平均值mean±SD(standard deviation)表示。統計方式使用成對t檢定(paired
ttest)分析各項百分比,以p值小於0.05判定為顯著差異。
(6) 羊肚菌菌絲體水萃物(WMe)之實驗結果如第1圖及下表1所示。圖片中為深紅色處為肌管,經過地塞米松處理後的C2C12肌管(右上),相較於沒有發生萎縮現象的對照組(Control,左上)組別,其肌管直徑明顯縮小(30.39µm→19.98µm),證明此模式確實會造成肌肉委縮。而加入羊肚菌菌絲體水萃物可顯著恢復肌肉直徑(右下,19.98µm→29.37µm)。不過,單純以羊肚菌菌絲體水萃物處理(左下)對肌肉質量並無顯著影響。

上述實驗證實本發明羊肚菌活性物質具有改善肌肉萎縮之作用。其可與藥學上可接受之載劑、賦形劑、稀釋劑或輔劑結合,製備醫藥組合物,亦可作為食品添加劑之用。
實施例三 羊肚菌活性物質 ( 水 / 醇萃取混合物 ) 增加肌肉質量、肌握力及肌耐力
目前已有實驗以cast immobilization(IM,利用固定式機械機構固定小鼠後肢,使其萎縮)方式誘導小鼠骨骼肌肉萎縮,可參照Peter Bialek, Carl Morris, Jascha Parkington, Michael St. Andre, Jane Owens, Paul Yaworsky, Howard Seeherman, and Scott A. Jelinsky, Distinct protein degradation profiles are induced by different disuse models of skeletal muscle atrophy,
Physiological Genomics, 2011 Oct;43(19):1075-1086此篇論文。本實驗中亦採相同方式,以cast immobilization (IM)方式誘導小鼠骨骼肌肉萎縮,待IM誘導達7天後,卸除IM,先測定肌握力測試,再測定肌耐力測試以定速18-20 m/min直至30 min(根據電擊次數)。試驗結束再進行犧牲,取其後肢骨骼肌肉並稱重記錄,評估羊肚菌菌絲體萃取混合物對增加肌肉質量、肌握力及肌耐力的結果。
(1) 利用C57BL/6J 小鼠進行動物實驗,分為對照組(Sham group)、IM組、羊肚菌菌絲體萃取混合物組,每組小鼠各6隻。對照組及IM組小鼠餵食等體積之二次純水(ddH
2O),試驗物質餵食劑量(即羊肚菌菌絲體之水/醇萃取混合物)濃度為500 mg/kg,試驗物質採用胃管經口餵食,其使用體積10 mL/kg b.w./次,試驗物質於投藥前現配,每日餵食後持續觀察,記錄體重、攝食與飲水重量。
(2) 小鼠經cast immobilization(IM)方式進行誘導肌少症病癥並同時給予羊肚菌菌絲體水/醇萃取混合物達第14天,進行小鼠肌握力及肌耐力測試(根據電擊次數)。試驗結束再進行犧牲,取其後肢骨骼肌肉並稱重記錄。
試驗結果均以Mean±SD表示,並使用GraphPad Prism (version 8.0)進行實驗數據統計分析。統計方法以單因子變異數分析(one-way ANOVA)及 Dunnett's test事後檢定 (post-hoc)分析判定組間差異。若統計結果p值小於0.05 (p<0.05)時,則判定兩組間具有顯著差異。
小鼠肌握力實驗結果如下表3所示。肌握力試驗係測量小鼠的最大抓握力,數值越高越佳。在第14天,IM組較Sham組的肌握力減少,而羊肚菌菌絲體水/醇萃取混合物組較IM組的肌握力顯著提升。

Cast Immobilization (IM) | 106.67±22.79# |
IM+羊肚菌菌絲體水/醇萃取混合物 | 118.43±24.94* |
小鼠肌耐力實驗結果如下表4所示,電擊次數越多耐力越差。在第14天,經IM處理過之負對造組肌耐力顯著下降,電擊次數較高(3.00→500.83)。使用羊肚菌菌絲體水/醇萃取混合物組較IM組的電擊次數顯著下降(500.83→78.50)。

Cast Immobilization (IM) | 500.83±257.37# |

犧牲小鼠取其後肢骨骼肌肉後,測量重量結果如下表5所示,IM的腓腸肌(gastrocnemius muscle)重量較對造組(Sham組)皆降低,而羊肚菌菌絲體水/醇萃取混合物組較IM組的腓腸肌重量具有增加趨勢。由此可證,本發明之羊肚菌菌絲體水/醇萃取混合物能夠增加肌肉重量。

上述實驗證實本發明之羊肚菌活性物質(水/醇萃取混合物)具有增加肌肉質量、肌握力及肌耐力之作用,而開發出羊肚菌於醫藥領域中的另一新穎用途。據此,為使羊肚菌之活性物質得以具體應用,製造一種包含羊肚菌之活性物質的組合物,並以一有效量施予一個體來達到治癒效果。
上述「有效量」係指一使用量,其足以使前述改善肌少症及/或增加肌肉質量、肌握力及/或肌耐力的效果產生。基於活體外細胞培養實驗,前述有效量係定義為「μg/ml」,其係基於每一個培養中所用之細胞培養液的總體積。基於動物模型實驗,前述有效量係定義為「g/60 kg body weight/day」。此外,經由活體外細胞培養實驗所得到的有效量數據可經下列計算公式而轉換為一合理之供動物使用的有效量:
一般來說(Reagan-Shaw et al., 2008),1「μg/ml」單位(基於活體外細胞培養實驗所得之有效量)可等同於1「mg/kg body weight/day」單位(基於老鼠模型實驗所得之有效量),並且,基於已知老鼠的新陳代謝率是人類的六倍,可進一步求得人類的有效劑量。
因此,若基於活體外細胞培養實驗求得有效量為500 μg/ml,則於老鼠中使用的有效量可計為500 mg/kg body weight/day(即,0.5 g/kg body weight/day)。進一步地,參酌前述新陳代謝率的差異,供人類使用的有效量則可計為5 g/60 kg body weight/day。
根據上述段落中所記載的試驗結果,基於小鼠實驗經驗證的有效量為500 mg/kg body weight/day,因此供人類使用之合理的有效劑量應為2.4 g/60 kg body weight/day。
一實施例中,組合物中所含的羊肚菌之活性物質的有效量為500 mg/60 kg-10g/60 kg body weight/day。
該組合物進一步包含添加劑。在一較佳的實施態樣中,該添加劑可為賦型劑、防腐劑、稀釋劑、填充劑、吸收促進劑、甜味劑、或其組合。該賦型劑可選自檸檬酸鈉、碳酸鈣、磷酸鈣或其組合。該防腐劑可延長醫藥組合物的儲藏期限,例如苯甲醇、對羥基苯甲酸(parabens)。稀釋劑可選自水、乙醇、丙二醇、甘油或其組合。填充劑可選自乳糖、牛乳糖、高分子量舉乙二醇或其組合。吸收促進劑可選自二甲基亞碸(DMSO)、月桂氮卓酮、丙二醇、甘油、聚乙二醇或其組合。甜味劑可選自安塞甜(Acesulfame K)、阿斯巴甜(aspartame)、糖精(saccharin)、三氯蔗糖/蔗糖素(sucralose)、紐甜(neotame)或其組合。除上述所列舉的添加劑以外,在不影響羊肚菌之活性物質的醫藥效果前提下,可依需求選用適合的其他添加劑。
該組合物於醫藥領域中可開發為不同商品。在一較佳實施態樣中,該組合物為一藥品、飼料、飲料、營養補充品、乳製品、食品或保健食品。
該組合物可根據受施予者之需要,而採用不同形態。在一較佳實施態樣中,該組合物的形態為粉劑、錠劑、造粒、栓劑、微膠囊、安瓶(ampoule/ampule)、液劑噴劑或塞劑。
本發明的組合物可使用於動物或是人類。在不影響羊肚菌之活性物質發揮效果的前提下,包含羊肚菌之活性物質的組合物可製為任何藥物型態,並根據藥物型態以適用的途徑施予該動物或人類。
組合物1:取水萃取物(20 wt%)作為羊肚菌活性物質,與作為防腐劑之苯甲醇(8wt%)、作為稀釋劑之甘油(7 wt%)充分混合,並溶於純水(65 wt%)中,以製得液體劑型之本發明之醫藥組合物,前述wt%係指各成分佔組合物總重之比例。存放於4℃備用。
組合物2:取乙醇萃取物(15 wt%)作為羊肚菌活性物質,與作為防腐劑之苯甲醇(5 wt%)、作為稀釋劑之甘油(10 wt%)充分混合,並溶於純水(70 wt%)中,以製得液體劑型之本發明之醫藥組合物,前述wt%係指各成分佔組合物總重之比例。存放於4℃備用。
雖然本發明已用實施例揭露如上,然其並非用以限制本發明。本領域之通常知識者,於參酌以上教示後,當能對上述實施例的內容進行適當修改,而仍然能達到本案所主張之功效。因此,本發明的保護範圍應以其後所附之申請專利範圍為準。
