It is used as a fiber for making clothes, and it has the effect of moistening, diuresis, and blood circulation. It is used for the treatment of rheumatism, pain, bruises, swelling (cold edema), dermatitis, and circumferential lymphadenitis.

Mulberry root bark is the root bark of mulberry or other cognate plants, tubular, semi-tubular, or banded bark, 0.1-0.6 cm thick, white-orange, and sometimes white silk-like. Many of the fibers are exposed. Usually, hypotensive flavonoids are the mainstream, and it is known to have a blood glucose enhancing function (Taro Nomura et al, Planta Med, 1, 127 (1984)).

In male expression, male impulse, skeletal muscle increase, male external genital development, scrotum growth, and spermatogenesis are involved in testosterone, and acne, sebum increase, hair loss and prostatic hyperplasia are related to dehydrotestosterone in the tissues. Known ( J. Invest. Dermatol . 1995; 105 (2): 209-14). Among male hormone-dependent diseases, male-type hair loss causes serious mental pain for men in the modern society, which focuses on beauty.

5alpha-reductase is present in testosterone, a testosterone biosynthesis in testes, present in testosterone-reactive tissues such as sebaceous glands, hair follicles, prostate, or epididymis, and dihydrotestosterone (DHT), an active testosterone. It is known to be a reductase involved in the conversion of NADPH as a coenzyme. Excessive secretion of dihydrotestosterone after puberty acts as a major causative agent in the production of sebum in sebocytes, causing acne and male hair loss. In particular, many hair follicle cells provide a cause for hair loss because dihydrotestosterone binds to hormone receptors better than testosterone. For this reason, studies are being actively conducted to develop a substance that inhibits the activity and production of 5-alpha-reductase, which promotes the production of dihydrotestosterone, and to use it as a hair regrowth or hair loss prevention agent.

Conventionally, female hormones such as estrogen have been used for the treatment of androgenetic alopecia, but female hormones have been reported to cause skin inflammation and side effects due to hormone administration. I'm using it. Recently, Merck in the United States has synthesized finasteride (finasteride, proscar), a drug that inhibits the action of 5 alpha-reductase and inhibits the production of dihydrotestosterone, and is commercially available as an oral administration hair regrowth, but is expensive and applied to the scalp If manufactured for direct application and the effect is ineffective and other side effects of oral administration occurs, there is a limit to use.

Normally, the dermal papilla cells that form hair follicles play a role as mediators of several signaling systems in the central position that regulates the hair cycle and have special functions to control epidermal cell proliferation. In addition, the thickness of the hair is determined in proportion to the size of the dermal papilla in the hair follicle, that is, the number of dermal papilla cells, and is an important criterion for distinguishing the cilia and the straight hair. Therefore, hair growth agents for promoting proliferation of outer root sheath cells and dermal papillae cells among hair follicle cells have been developed (J Dermatol Sci 1994 Jul; 7 Suppl: S55-72).

There are three pathways through the skin: absorption through the stratum corneum, absorption through the hair follicle and sebaceous glands, and absorption through the eccrine gland. As far as is known, absorption through the stratum corneum is the most important absorption pathway. Since the stratum corneum is composed of nonpolar lipids in the stratum corneum, the polar substance is hardly absorbed and the lipophilic substance can be absorbed. have. In the case of a polar substance, it is combined with a protein part in the cytoplasm or interstices by a hydrogen bonding method and is not absorbed through the skin. Nonpolar substances, on the other hand, are primarily dissolved in the cell gap and sometimes cross the skin barrier. However, even through the stratum corneum, the solubility in the lower stratum corneum is less, it is prevented from being absorbed systemically by mechanisms such as enzymes that cause various metabolism and the exfoliation of keratinocytes. On this principle, the stratum corneum protects the body from numerous external polar substances, but nonpolar poisons can be absorbed into the stratum corneum. The greatest barrier to transdermal absorption is keratinocytes in the stratum corneum as described above and keratinocyte lipids therebetween. Since most of the active ingredients have a low percutaneous permeability due to the resistance of the stratum corneum, various methods are needed to overcome them and promote permeation of the active ingredients. The mixing of lipophilic substances with ethanol, propylene glycol, surfactants, fatty acids, etc. is a very effective method of transdermal delivery of components at the required speed and effective concentration. In addition, the use of liposomes made of lecithin or intercellular lipid components of the active ingredient is a much more effective method of transdermal absorption (Patent No. 2001-0083712).

Liposome preparations that began to emerge from the 70s as a means of penetration of drugs in the skin were observed, and corticosteroids and betamethasone were observed to be effective in skin permeation compared to general emulsion formulations (Crit Rev Ther). Drug Carrier Syst 1994; 11 (2-3): 97-118). From these results, an effective drug delivery system to hair follicles has been conducted by various research groups, and in fact, studies have been carried out to collect and deliver fluorescent dyes that can be distinguished by genes, proteins and the naked eye into hair follicles as liposomes. J Drug Target. 1998; 5 (2): 67-74). For example, when infiltrating hair follicles with melanin in the form of liposomes, the concentrations in the hair follicles increased with time but were not detected in the blood at all (J Dermatol Sci 1997; 14: 101-8). In another experiment, the lacZ gene was wrapped in liposomes and applied to rats, which showed selective expression only in the bulge area where hair matrix cells and stem cells are known. No other site was observed (Nature Medicine 1995; 1: 705-6). The particle size of liposomes was 60 nm to 600 nm, the smallest of which was accumulated in the stratum corneum, the largest size of 300 nm in the follicle depth (Int J Pharm 1994; 103: 277). Considering the fact that anti-androgen receptors are widely distributed in sebaceous glands and anti-androgen agents have limited effects and systemic side effects during oral administration, the infiltration of anti-androgen agents into liposomes in the form of liposomes is under study (Int J Pharm 1995; 126: 235.

Therefore, the present inventors tested 9 natural plant extracts for promoting hair follicle cell proliferation and 5 alpha-reductase inhibitory effects by in vitro test methods, and the natural extract of the present invention converts testosterone to dihydrotestosterone to reduce hair loss. It effectively inhibits the 5 alpha-reducing enzymes that induce and contains a large amount of active substances that promote hair follicle cell proliferation, so that it has an excellent hair growth promoting effect. The liposome base is prepared to contain such extracts and used for external skin preparations for hair growth promotion. The present invention has been completed.
