The antibodies remove and inactivate antigens. Antibodies are distributed in internal body and mucosal membrane to protect living animals, but they are excellent proteins that can exert their functions, “antigen-antibody reactions,” even when removed from the body. For that reason, antibodies are being put to practical use in diagnostic kits for conditions such as pregnancy and influenza infection, and as anticancer drugs targeting specific tumor markers. The result has been an increasing use of antibodies for research, diagnosis, and therapeutic purposes. Unfortunately, antibodies from experimental mammals such as mice, rats, and rabbits, are not suited to industrial use because of their high production cost. Moreover, handling of these antibodies is difficult due to their vulnerability to heat, acids and alkalis. Accordingly, there is no adaptability to mass production. Recently, we developed a convenient method for the low-cost, mass-production of antibodies using egg-laying hen ostriches. The ostrich egg is an excellent source of antibodies for industrial purposes. The present report shows that the ostrich antibodies have therapeutic effects in ailments such as atopic dermatitis, acne, pyoderma, and pollen allergies. We have successfully produced and purified ostrich immunoglobulin yolk (IgY) against pollen allergens (Cryj1, Cryj2, Chao1, Chao2) and found that allergic reactions were alleviated in skin patch tests of allergic patients by using the ostrich IgY. In addition, we produced ostrich IgY against the homogenates of Staphylococcus aureus and Propionibacterium acnes, and applied to dermal lesions of atopic dermatitis and acne patients, and then observed the therapeutic effects on the dermatitis of volunteer subjects. Antibody against S. aureus also had the therapeutic effect on canine pyoderma caused by MRSA. A particular advantage in using ostrich antibodies is the fact that they inactivate and neutralize a specific antigen, without damaging the indigenous microflora of the dermal surface. In this review article and case repot, we wish to suggest that ostrich antibodies can contribute to the treatment of cutaneous disorders as an alternative to treatment with steroids or antibiotics.展开更多

Also, dermal bacteria and their toxins have been implicated in hair loss. A preliminary study by the authors with six male volunteer subjects showed that ostrich antibodies against above causative substances were quite effective in promoting hair regrowth. The present study included 13 men and 4 women, with ages ranging from 39 to 78. Pre- and post-treatment hair counts were also incorporated into the study procedure. In all instances but one, the subjects had a hair-growth effect about 3 months after the antibody was applied to the scalp, and the study participants with hair growth were pleased with the results and with the ease of use of the antibody solution.展开更多

Recently, some chemicals against these hormones have been commercialized as therapeutics for AGA. In the present study, we have attempted to find out the potential effects of antibodies on AGA therapeutics as an inhibitor of androgenic hormones. The immune system of the ostrich is believed to be the most versatile and powerful of any animal on the planet, and antibodies derived from the ostrich egg yolk are now being developed for a wide range of diseases and ailments. Ostrich antibodies against DHT and 5α-reductase have been produced and combined with antibodies against harmful skin bacteria to restore normal hair growth in AGA cases. Preliminary testing with six volunteer subjects showed that ostrich antibodies were clearly quite effective in hair regrowth.展开更多
