Description

【0001】
【発明の属する技術分野】
【0002】
本発明は抗腎機能不全薬及びそれを用いた方法、特に天然物由来の抗腎機能不全薬に関する。
【0003】
【従来の技術】
腎機能不全を生じる原因は多々あり、またその結果発現する症状も各種考えられるが、一般的に腎機能不全の初期症状は判別しにくくさらに慢性化しやすいため、有効な腎機能不全の予防、治療手段の要望は大きい。
そして、長期にわたる予防、治療薬の投与は、患者に負担を与える可能性が大きく、投与薬の長期連用による副作用はきわめて大きな問題である。
【0004】
【発明が解決しようとする課題】
しかしながら、従来において、長期にわたり連用しても、副作用を生じる可能性の低い抗腎機能不全薬は少なく、その開発が望まれていた。
本発明は前記従来技術の課題に鑑みなされたものであり、その目的は急性毒性のみならず、長期連用による副作用も実質的に発現しない、安全性の高い抗腎機能不全薬及び方法を提供することにある。
【0005】
【課題を解決するための手段】
前記目的を達成するために本発明者らが鋭意検討を行った結果、食用にも用い得るアガリクス・ブラゼーに優れた抗腎機能不全作用が存在することを見いだし、本発明を完成するに至った。
すなわち、本発明にかかる抗腎機能不全薬は、アガリクス・ブラゼー抽出物を主成分とすることを特徴とする。
また、前記抗腎機能不全薬において、アガリクス・ブラゼー抽出物は、アガリクス・ブラゼー乾燥粉末を熱水抽出したものを主成分とすることが好適である。また、本発明にかかる抗腎機能不全方法は、アガリクス・ブラゼー抽出物を有効量投与することを特徴とする。
【0006】
なお、抗腎機能不全薬として用いる際の投与量は、症状などにより大きく異なるが、おおよそ1〜10gアガリクス・ブラゼー乾燥粉末/dayとなる程度に熱水抽出物を摂取することで充分な効果を期待できる。
なお、ここでアガリクス・ブラゼーとは、学名をAgarucus blazei Murillといい、日本ではハラタケ科ハラタケ属のキノコでヒメマツタケ、或いはカワリハラタケと呼ばれる。
【0007】
天然には草地に発生する。収穫期の傘はまんじゅう型(直径5〜10cm)で表面は褐色の鱗片で覆われる。ひだの形成は密で、傘の開きに伴って白色から黒褐色になる。柄は白色で基部が若干膨らみを持ち長さ5〜10cm、太さ2〜3cmで内部は多くの場合、中空である。膜質で早落性の内皮膜を持ち下面は綿くず状である。胞子は6×3μm程度の楕円形で、胞子紋は茶褐色〜黒褐色。菌糸体は樹枝状に伸長成長する。
【0008】
栽培は、サトウキビの葉、頂頭部、バカス、稲藁及び馬糞などを原材料としてpH6.5、含水率70%、C/N比45の状態で熟成した堆肥に菌糸体を接種して埴壌土によって覆土処理した後、温度25℃、湿度80%以上で500lxの光照射下で培養し、菌糸体接種後30〜120日の間に連続的に子実体を収穫できる。
【0009】
従来、アガリクス・ブラゼーは子実体乾燥物を熱水抽出して得た抽出液を飲用する利用法が一般的であり、前臨床、及び臨床試験からガン、肝臓病、糖尿病、高血圧症、アトピー性皮膚炎、膠原病、全身性エリテマトーデス、慢性間接リウマチなどに有効であり、免疫調整作用及び抗炎症作用を有することが知られているが、抗腎機能不全機能については全く知られていなかった。
【0010】
【発明の実施の形態】
以下、本発明の好適な実施形態について説明する。
まず、本発明にかかる抗腎機能不全薬の効果確認方法を図1の試験スケジュールに従って説明する。
【0011】
被検試料の調製
乾燥アガリクス・ブラゼー5gを600mlの80℃熱水で1時間抽出し、被検試料を得た。
供試ラット
Wistar系雄性ラット(6週齢 体重約180g)を日本チャールズリバー株式会社から購入後、室温22±1℃、湿度60%に調整された部屋で明時間(12時間)、暗時間(12時間)となるように光調整し、1週間予備飼育した。
【0012】
DOCA食塩高血圧症の誘発及び飼育方法
腎性高血圧症の誘発は、ネンプタール麻酔下で左腎を摘出し、1週間後から酢酸デオキシコルチコステロン(DOCA)を、0.5%カルボキシメチルセルロース(CMC)を含む0.9%食塩水中に、4mg/mlとなるように懸濁し、5ml/kgB.W.の投与量に調整して週1回背部に皮下注射した。一方、疑似手術処置を行った群(Sham)は、CMC溶液を皮下注射した。片腎摘出群はさらに手術翌日よりヒメマツタケ熱水抽出物を経口的に自由摂取した群(DOCA−1st、n=7)、血圧上昇後にヒメマツタケ熱水抽出物を経口的に自由摂取した群(DOCA−2nd、n=8)及び滅菌水投与群(DOCA−con、n=6)の3群に分けた。また、疑似手術処置群は手術翌日よりヒメマツタケ熱水抽出物を投与した群(Sham−AB、n=4)と滅菌水投与群(Sham−con、n=4)の2群に分け、合計5群とした。飲料水としてヒメマツタケ熱水抽出物投与群には1%食塩を含むヒメマツタケ熱水抽出物を、滅菌水投与群には1%食塩水を自由摂取させた。ヒメマツタケ熱水抽出物は週平均飲用量から換算して5g(子実体乾燥粉末重量)/60kg B.W./dayとなるように滅菌水で希釈して調製した。なお、抽出物からの沈殿物の発生を防ぐため、12時間毎に抽出物を交換した。飼料は固形飼料(NMF、オリエンタル酵母工業(株))を自由摂取させた。ラットは湿度22±1℃、湿度60%の環境下、12時間明暗サイクルの日付変動を考慮した飼育室で飼育した。
【0013】
各ラットの摂食量、飲用量及び尿量を毎日9:30〜12:00に測定した。
飼育期間終了後、ラットは12時間絶食の後、ネンブタール深睡眠下、心臓穿刺により採血し、高血圧症について血液生化学検査を行った。
結果を以下に示す。
【0014】
[試験結果]
尿量及び飲水量の変動
図2に飲水量変化を示す。
同図より明らかなように、Sham群と片腎摘出群(DOCA群)の飲水量を比較すると、DOCA投与開始後から片腎摘出群の飲水量はSham群よりも増量しており、DOCA投与41日以降ではSham群と比較して明らかな差異が確認できた。さらに、片腎摘出群ではアガリクス・ブラゼー飲用両群(DOCA−1st,DOCA−2nd)の方が未適用群(DOCA−Con)と比較して飲用水量の減少傾向が認められた。
【0015】
また、図3に尿量変化を示す。
尿量の変動は、Sham群と比較してDOCA群の方が腎摘出当初から尿量の増量が認められ、DOCA投与41日以降では両群の差は顕著であった。なお、アガリクス・ブラゼー飲用群では、血圧上昇がピーク値となったDOCA投与41日以降に連用させた群(DOCA−2nd)は未投与群(DOCA−Con)と比較して尿量が抑制傾向にあった。そして、DOCA投与41日以降から血圧は最高値に達し、その後ほぼ一定の高血圧症状となった。
【0016】
以上の成績は片腎摘出及びDOCA/NaCl負荷によって明らかな腎排泄機能障害の生じることを示唆し、且つアガリクス・ブラゼー飲用群は尿崩症を改善することを示唆している。
【0017】
腎重量の変動
図4に腎重量の変動を示す。
DOCA投与(腎摘出)90日目のSham群及びDOCA群、無処置群(WKY)の腎重量を比較した。Sham群ではアガリクス・ブラゼーを飲用させた群(Sham−AB)、未適用群(Sham−Con)もほぼ同じで約1.9gであった。しかも、この重量は無処置のラットと同様な重量であった。しかし、DOCA群は倍以上の約4g以上と著明な腎の重量増加とともに著しい肥大が観察された。一方、DOCA群ではアガリクス・ブラゼーを連続飲用させた群(DOCA−1st)と腎摘出41日以降から連続服用させた群(DOCA−2nd)の腎肥大ならびに異常な腎重量の増加は未適用群と比較して明らかに減少していた。さらに、DOCA−1st群はSham群と比較して肥大は認められるものの腎重量は近似値を示した。
【0018】
以上の成績は、片腎摘出及びDOCA/NaCl負荷によって明らかな腎肥大に伴う腎障害を誘発させることを示唆し、且つ、アガリクス・ブラゼー飲用は改善作用を有することを示唆している。
【0019】
血液検査値の変動
表1にはDOCA投与(腎摘出)90日目のSham群及びDOCA群の血液検査値を比較した。
【表1】

Figure 0004348443
【0020】
前記表1より明らかなように、Sham群はアガリクス・ブラゼーの飲用有無の両群において著明な差が見られる検査項目はなかった。これらの値に対してDOCA群のアガリクス・ブラゼー未適用群(DOCA−Con)は肝機能を反映する検査項目には著明な差異は有していなかったが、A/G比、BUN(血液尿素態窒素)、クレアチニンのような腎機能を反映する検査項目に著明な差が認められた。さらに、総コレステロール値(T−Cho)、CRP、総タンパク量(TP)、アルブミン値に有意な差が認められることから、腎排泄機能調節に著しい障害が生じていることが推測された。
【0021】
一方、アガリクス・ブラゼー飲用の両群(DOCA−1st,DOCA−2nd)は未適用群と比較して著明な改善効果が腎機能系の検査項目に認められた。ことに、DOCA群でアガリクス・ブラゼーを連続飲用させた群(DOCA−1st)では改善項目によってはSham群と近似になった検査値が認められた。これらの成績は、前述した尿量、腎重量の異常な増加や肥大との成績を加味すると、片腎摘出ラットにDOCAならびにNaCl負荷を処置することによって明らかな腎機能障害、ことに組織崩壊を誘発させることが考えられた。さらに、アガリクス・ブラゼー飲用は改善作用を有することを示唆している。
【0022】
尿検査値の変動
表2にはDOCA投与(腎摘出)90日目のSham群及びDOCA群の尿検査値を比較した。
【表2】
Figure 0004348443
【0023】
前記表2より明らかなように、Sham群はアガリクス・ブラゼーの飲用有無の両群において著明な差が認められる検査項目はなかったものの、クレアチンやリン(P)の排泄がアガリクス・ブラゼーの飲用によって増加されることが考えられる。DOCA群(DOCA−Con)はSham群と比較すると尿比重を除くいずれの検査項目でも著明な差が認められ、腎機能障害の発現が推測された。一方、DOCA群のアガリクス・ブラゼー服用群には、タンパク質排泄に著明な改善効果が認められた。
【0024】
これらの成績は、腎機能が片腎摘出ラットにDOCAならびにNaCl負荷を処置することによって重篤な障害を受けていることを示しており、しかも尿細管系の重篤な機能不全を示唆する。これらの機能不全に対して、アガリクス・ブラゼー服用は尿タンパク質の異常排泄を抑制したことから、腎炎やネフローゼ症候群への治療効果が期待できるものと思われる。
【0025】
腎の病理学的所見
腎の組織写真を図5(Sham群)、図6(DOCA−con群)、図7(DOCA−1st群)に示した。
Sham群にはいずれの群においても顕著な腎組織障害は認められていなかった。しかし、DOCA−con群はいずれも顕著な腎組織障害が認められており、ことに、硬化性、硝子円様が観察され、尿細管上皮脱落や尿細管壊死脱落の生じていることが明確となった。これらの病理所見は前述した剖検ならびに生化学的検査結果における考察を指示すると考えられる。一方、アガリクス・ブラゼー服用群は病理組織所見でも統計学的に有意な差を持って組織障害の発現を抑制することが明らかとなった。
【0026】
本病理所見による成績から、片腎摘出ラットにDOCAならびにNaCl負荷を処置することによって重篤な尿細管系の機能不全、さらには腎硬化症を誘発させることが明確となった。しかも、アガリクス・ブラゼー服用によって著明にこれらの疾患誘発が抑制されており、併用時期に差異のないことから、予防のみならず治療にも効果を有する可能性のあること、及び腎透析における併用効果が期待される。
【0027】
内分泌物質の変動
腎機能に関与する内分泌物質のうち、レニン、アルドステロン、コルチゾール、アンギオテンシンIIの変動について検討を行った。表3にその結果を示す。
【表3】
Figure 0004348443
【0028】
前記試験結果より、片腎摘出ラットにDOCAならびにNaCl負荷を処置することによって重篤な腎機能不全の誘発が観察される。そのため、表3に示す如く高血圧性障害と深く関連性を有するレニン、アンギオテンシンIIは、DOCA群で著明な減少が認められた。さらに、腎機能と付随する副腎皮質ホルモンのアルドステロンやコルチゾールの値も著明な低下が観察された。一方、アガリクス・ブラゼー服用群は腎機能関連の内分泌物質の低下に対する抑制効果はSham群にまでは回復を示さないものの有意な差をもって改善効果を有することが判明した。さらに、興味のあることは、副腎皮質の内分泌物質の低下を著明に改善することから、免疫系或いは内分泌機能の保護作用を有することが推測される。
【0029】
以上の結果、薬物誘発腎機能障害に対するアガリクス・ブラゼーの効果について、以下のことが確認乃至示唆された。
片腎摘出ラットにDOCAならびにNaCl負荷を処置することによって重篤な腎機能不全が誘発された。しかもこの腎障害は尿細管壊死脱落を伴い、腎硬化症を惹起するものであった。
【0030】
アガリクス・ブラゼー連続服用は著明にDOCA誘発の腎障害を改善し、投与時期(血圧の上昇前と後)に差のないことから予防のみならず治療効果をも有する可能性が考えられた。
アガリクス・ブラゼー服用による腎障害改善効果は副腎機能を改善させ、しかも尿細管排泄機能を回復させることから生じるものと思われる。
【0031】
アガリクス・ブラゼー服用は、腎不全、尿細管転送障害、ネフローゼ症候群、腎硬化症、尿毒症、間質性腎炎、糸球体腎炎、腎移植予後治療、腎透析併用治療、水腎症の予防ならびに治療に効果的であることが示唆される。
なお、本発明にかかる抗腎機能不全薬は、内服剤、注射剤のいずれの剤型を用いることも可能である。
【0032】
内服剤として用いる場合には通常、他の増量剤、賦型剤とともに用いて、散剤、錠剤、カプセル剤、顆粒剤、茶剤、懸濁化剤、流エキス剤、液剤等の形態をとる。
また、注射剤の場合には、懸濁液、溶液、油性又は水性ビヒクル中の乳液のような形態をとることができ、懸濁化剤、安定化剤及び分散剤のような処方剤を含むことも可能である。
【0033】
【発明の効果】
以上説明したように、本発明にかかる抗腎機能不全薬及び方法は、食用可能なアガリクス・ブラゼーを主成分とするので、長期連用による安全性もきわめて高く、腎機能不全の予防、治療にきわめて有効である。

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described.
First, the method for confirming the effect of the anti-renal dysfunction drug according to the present invention will be described according to the test schedule of FIG.
[0011]
Preparation of test sample 5 g of dry Agaricus blaze was extracted with 600 ml of hot water at 80C for 1 hour to obtain a test sample.
Test rat
After purchasing Wistar male rats (6 weeks old, approximately 180 g body weight) from Nippon Charles River Co., Ltd. in a room adjusted to room temperature 22 ± 1 ° C and humidity 60%, light time (12 hours), dark time (12 hours) The light was adjusted so that
[0012]
Induction and breeding method of DOCA salt hypertension In order to induce renal hypertension, the left kidney was removed under Neptal anesthesia, and after 1 week, deoxycorticosterone acetate (DOCA) was added with 0.5% carboxy. Suspended in 0.9% saline containing methylcellulose (CMC) to a concentration of 4 mg / ml, 5 ml / kg B.V. W. Was administered subcutaneously at the back of the dog once a week. On the other hand, the group (Sham) that performed the sham operation was injected with the CMC solution subcutaneously. The single nephrectomy group was a group (DOCA-1st, n = 7) that was orally freely ingested Himematsutake hot water extract from the day after the operation, and a group (DOCA) that was orally freely ingested Himematsutake hot water extract after increasing blood pressure. -2nd, n = 8) and sterilized water administration group (DOCA-con, n = 6). In addition, the sham operation treatment group was divided into two groups, a group (Sham-AB, n = 4) to which the extract of himematsutake hot water was administered from the day after the operation, and a sterilized water administration group (Sham-con, n = 4), for a total of 5 Grouped. As a drinking water, a himematsutake hot water extract containing 1% sodium chloride was freely administered to a himematsutake hot water extract administration group, and a 1% saline was freely consumed to a sterilized water administration group. The Japanese red pine mushroom hot water extract is 5 g (weight of dried fruit body) / 60 kg in terms of the average weekly dose. W. / Day was prepared by diluting with sterilized water. In addition, in order to prevent generation | occurrence | production of the precipitate from an extract, the extract was replaced every 12 hours. As the feed, solid feed (NMF, Oriental Yeast Co., Ltd.) was freely ingested. Rats were bred in a breeding room in consideration of date variation of a 12-hour light-dark cycle in an environment of humidity 22 ± 1 ° C. and humidity 60%.
[0013]
The intake, drinking and urine volume of each rat was measured daily from 9:30 to 12:00.
At the end of the breeding period, the rats were fasted for 12 hours, then blood was collected by deep-sleeping Nembutal by cardiac puncture, and blood biochemical tests were performed for hypertension.
The results are shown below.
[0014]
[Test results]
Changes in urine volume and drinking water Figure 2 shows changes in drinking water.
As is clear from the figure, when comparing the amount of water consumed between the Sham group and the one-sided nephrectomy group (DOCA group), the amount of water consumed in the one-sided nephrectomy group has increased from the Sham group since the start of DOCA administration. After 41 days, a clear difference was confirmed compared with the Sham group. Further, in the nephrectomy group, both Agaricus Blaze drinking groups (DOCA-1st, DOCA-2nd) showed a tendency to decrease the amount of drinking water compared to the unapplied group (DOCA-Con).
[0015]
FIG. 3 shows changes in urine volume.
As for fluctuations in urine volume, an increase in urine volume was observed in the DOCA group compared to the Sham group from the beginning of nephrectomy, and the difference between the two groups was remarkable after 41 days of DOCA administration. In addition, in the Agaricus blaze drinking group, the group (DOCA-2nd) continuously used after the 41st day of DOCA administration in which the rise in blood pressure reached the peak value tends to suppress urine volume compared to the non-administered group (DOCA-Con). It was in. The blood pressure reached the highest value after 41 days after DOCA administration, and thereafter became almost constant hypertension.
[0016]
The above results suggest that unilateral nephrectomy and DOCA / NaCl loading cause obvious renal excretion dysfunction, and that the Agaricus blaze drinking group improves diabetes insipidus.
[0017]
Changes in kidney weight Figure 4 shows changes in kidney weight.
The kidney weights of the Sham group, the DOCA group, and the untreated group (WKY) on the 90th day after DOCA administration (nephrectomy) were compared. In the Sham group, the group in which Agaricus Blaze was drunk (Sham-AB) and the unapplied group (Sham-Con) were almost the same, and the weight was about 1.9 g. Moreover, this weight was the same as that of the untreated rat. However, in the DOCA group, significant enlargement was observed with a significant increase in the weight of the kidney, approximately 4 g or more, which is more than double. On the other hand, in the DOCA group, renal hypertrophy and abnormal increase in renal weight were not applied in the group in which Agaricus blaze was continuously taken (DOCA-1st) and the group in which it was continuously taken after 41 days after nephrectomy (DOCA-2nd). It was clearly reduced compared to Furthermore, although the DOCA-1st group showed enlargement compared with the Sham group, the kidney weight showed an approximate value.
[0018]
The above results suggest that nephrotomy and DOCA / NaCl loading induce renal damage associated with apparent renal enlargement, and that Agaricus blaze drinking has an improving effect.
[0019]
Changes in blood test values Table 1 compares the blood test values of the Sham group and the DOCA group on day 90 of DOCA administration (nephrectomy).
[Table 1]
Figure 0004348443
[0020]
As apparent from Table 1, there was no test item in which the Sham group showed a significant difference between the two groups regarding whether or not to take Agaricus blaze. For these values, the Agaricus Blaze unapplied group (DOCA-Con) in the DOCA group did not have a significant difference in test items reflecting liver function, but the A / G ratio, BUN (blood A significant difference was observed in the examination items reflecting the renal function such as urea nitrogen) and creatinine. Furthermore, since significant differences were observed in the total cholesterol level (T-Cho), CRP, total protein level (TP), and albumin level, it was speculated that a significant disorder occurred in the regulation of renal excretion function.
[0021]
On the other hand, both groups (DOCA-1st, DOCA-2nd) for drinking Agaricus blaze showed a marked improvement effect in the examination items of the renal function system as compared with the unapplied group. In particular, in the DOCA group, a test value that was similar to the Sham group was observed in the group (DOCA-1st) in which Agaricus blaze was continuously taken depending on the improvement item. These results are based on the above-mentioned results of abnormal increase in urine volume, kidney weight, and hypertrophy, and apparent renal dysfunction, especially tissue disintegration, by treating DOCT and NaCl load on unilaterally isolated rats. It was thought to induce. Furthermore, Agaricus blaze drinking suggests that it has an improving effect.
[0022]
Changes in urinalysis values Table 2 compares the urinalysis values of the Sham group and DOCA group on day 90 of DOCA administration (nephrectomy).
[Table 2]
Figure 0004348443
[0023]
As is clear from Table 2 above, there was no examination item in which the Sham group had a significant difference between the two groups with or without Agaricus Blaze, but the excretion of creatine and phosphorus (P) was drunk with Agaricus Blaze. It can be increased by. In the DOCA group (DOCA-Con), as compared with the Sham group, a significant difference was observed in any of the test items except the urine specific gravity, and the expression of renal dysfunction was estimated. On the other hand, a marked improvement effect on protein excretion was observed in the DOCA group taking Agaricus blaze.
[0024]
These results indicate that renal function is severely impaired by treating DOCA as well as NaCl load in single nephrectomized rats and suggests severe dysfunction of the tubular system. For these dysfunctions, Agaricus Blaze can suppress the abnormal excretion of urine protein, and it can be expected to have a therapeutic effect on nephritis and nephrotic syndrome.
[0025]
Renal pathological findings The histological photographs of the kidney are shown in Fig. 5 (Sham group), Fig. 6 (DOCA-con group), and Fig. 7 (DOCA-1st group).
In the Sham group, no remarkable renal tissue damage was observed in any group. However, in all of the DOCA-con groups, remarkable renal tissue damage was observed, and in particular, sclerosis and vitreous circle were observed, and it was clear that tubular epithelial loss and tubular necrosis loss occurred. became. These pathological findings are thought to indicate consideration in the autopsy and biochemical results described above. On the other hand, it was revealed that the Agaricus blaze group had a statistically significant difference in histopathological findings and suppressed the occurrence of tissue damage.
[0026]
From the results of this pathological finding, it was clarified that treatment of DOCA and NaCl load on single nephrectomized rats induces severe tubule dysfunction and nephrosclerosis. Moreover, the induction of these diseases is markedly suppressed by taking Agaricus Blaze, and there is no difference in the timing of combination, so it may be effective not only for prevention but also for treatment, and combined use in renal dialysis Expected to be effective.
[0027]
Changes in endocrine substances Among endocrine substances involved in renal function, changes in renin, aldosterone, cortisol, and angiotensin II were examined. Table 3 shows the results.
[Table 3]
Figure 0004348443
[0028]
From the above test results, induction of severe renal dysfunction is observed by treating DOCA as well as NaCl loading in single nephrectomized rats. Therefore, as shown in Table 3, renin and angiotensin II, which are deeply related to hypertensive disorders, were significantly decreased in the DOCA group. In addition, the levels of aldosterone and cortisol, adrenal cortical hormones associated with renal function, were also markedly reduced. On the other hand, the Agaricus blaze group was found to have an improvement effect with a significant difference, although the inhibitory effect on the decrease in endocrine substances related to renal function did not recover to the Sham group. Furthermore, it is presumed that the substance has a protective effect on the immune system or endocrine function because it significantly improves the decrease in endocrine substances in the adrenal cortex.
[0029]
As a result, the following was confirmed or suggested for the effect of Agaricus blaze on drug-induced renal dysfunction.
Severe renal dysfunction was induced by treatment of DOCA as well as NaCl loading in single nephrectomized rats. Moreover, this renal disorder is accompanied by tubule necrosis and causes nephrosclerosis.
[0030]
The continuous use of Agaricus blaze markedly improved DOCA-induced renal damage, and there was no difference in the timing of administration (before and after blood pressure increase), suggesting the possibility of having therapeutic effects as well as prevention.
It is considered that the renal disorder improving effect by taking Agaricus blaze results from improving the adrenal function and restoring the tubular excretion function.
[0031]
Agaricus Blaze can be used for renal failure, renal tubular transfer disorder, nephrotic syndrome, nephrosclerosis, uremic disease, interstitial nephritis, glomerulonephritis, renal transplantation prognosis treatment, renal dialysis combined treatment, hydronephrosis prevention and treatment It is suggested that this is effective.
In addition, as the anti-renal dysfunction drug according to the present invention, any dosage form of internal use and injection can be used.
[0032]
When used as an internal preparation, it is usually used with other fillers and excipients in the form of powders, tablets, capsules, granules, teas, suspending agents, fluid extracts, liquids and the like.
In the case of injections, it can take the form of suspensions, solutions, emulsions in oily or aqueous vehicles, including formulations such as suspending, stabilizing and dispersing agents. It is also possible.
[0033]
【The invention's effect】
As described above, since the anti-renal dysfunction drug and method according to the present invention is mainly composed of edible Agaricus blaze, it is extremely safe for long-term continuous use, and is extremely useful for the prevention and treatment of renal dysfunction. It is valid.
