Abstract
The present invention relates to new medicinal use of Chinese medicine nutmeg and its extract. Specifically, nutmeg and its extract is used in preparing 5alpha-reductase inhibitor and prostatic hyperplasia treating medicine with obvious curative effect, low cost and convenient use.
Description
Technical field
The present invention relates to the myristic new purposes of Chinese medicine, specifically, is the application in preparation 5 inhibitor and preparation treatment prostatic hyperplasia medicine, belongs to the field of Chinese medicines.
Background technology
Benign prostate hyperplasia (BPH) is a prostate hyperplasia, it is the elderly men common disease, blocking with the firm static due to the prostatic hyperplasia that dynamic property due to increasing with prostate smooth muscle tension force blocks is feature, clinical manifestation is residual for the bladder urine flows out obstruction, urgent micturition, frequent micturition, urine, often cause urinary tract infection even bring out nephritis, its sickness rate increased progressively with the age, the number of falling ill in recent years also obviously increases, seriously influence patient's physical exertion and social competence, thereby influence its quality of life.BPH adopts surgical result good mostly, but operation is not to have no danger for elderly patients, the BPH operation is a kind of traumatic and destructive procedure, death risk is arranged, therefore to seek the risk of Drug therapy to avoid performing the operation, and constantly perfect along with what the hyperplasia of prostate pathogeny was familiar with, medicine has become the important means of BPH treatment.
Though at present BPH the cutter reason takes place does not really also illustrate fully, the 5-alpha-reductase is widely accepted with the relation of BHP generation.The effect of 5-alpha-reductase is to make testosterone (T) metabolism be dihydrotestosterone (DHT), and is relevant with the generation of BPH.Studies show that simultaneously: 5 is the key enzyme of skin male hormone metabolism, the discovered in recent years various skin is sick relevant unusually with male hormone metabolism, some 5 inhibitor have been used for androgenetic alopecia and other androgen dependency dermatosiss, as (Yin Xingping such as acne, hirsutisms, Xia Long celebrating .5a-reductase in male hormone metabolism effect and inhibitor in the application of department of dermatologry. foreign medical science skin cypridology fascicle, 2004,30 (6): 375～377).DHT is the activity form of prostate androgen, by prostate breaks up, growth promoter is essential.But in the geratic period, prostata tissue keeps very high 5-alpha-reductase activity, and DHT content is raise, and therefore thinks to cause the key factor of prostatic hyperplasia.This theory is confirmed by a kind of research of 5-alpha reductase inhibitor finasteride.Finasteride reduces testosterone with competitive combination of 5 and combines with 5, and the blocking-up testosterone transforms to DHT, and the interior DHT of plasma D HT and prostate is descended rapidly, prostate is dwindled, and increase the urine flow rate, and improve and block symptom, reduce the complication of BPH.In recent years, the medicine of plant origin shows the good prospect of treatment BPH, as saw palmetto berry extract and pollen extract (Prostat), all has the effect that suppresses 5.
