Description

근시 치료제의 제조방법Method of manufacturing myopia treatment

본 발명은 근시 치료 및 근시 진행을 예방하기 위한 근시 치료제의 제조방법에 관한 것이다.The present invention relates to a method for preparing a myopia therapeutic agent for treating myopia and preventing myopia progression.

근시의 빈도는 미국의 경우 전인구의 25%를 차지하고 있으며, 근시는 축성근시 즉, 안구의 길이(안축장)가 길어서 발생한 한 근시가 대부분인바, 근시의 발생원인은 여러 가지 요인이 있고 이중 유전적 요인과 환경적 요인에 대한 끊임없는 연구의 결과로, 현재로서는 안구가 팽창되어 안축장이 길어지는 것이 아니고 안구의 성장속도에 의해서 안축장이 정상보다 길어지고 따라서 근시가 유발된다는 가설에 많은 학자들의 실험이 이를 뒷받침하고 있다.The frequency of myopia accounts for 25% of the total population in the United States. Myopia is the most common cause of myopia, i.e., myopic length due to long eye length. As a result of the constant research on the environmental and environmental factors, many scholars have experimented with the hypothesis that the eyeball is not expanded due to the expansion of the eye axis at this time, but that the eye axis is longer than normal due to the rate of eye growth and thus myopia is induced. Supported.

본 발명자의 실험적 조사 유발실험에 의하면 부화된지 2일된 병아리에서 한눈의 안검을 봉합하고 6주간 사육하면 안검 봉합으로 시 자극이 차단된 눈의 안축장이 12.57±0.67㎜로서 대조안의 12.03±0.41㎜보다 통계학적으로 유의하게 증가하여 근시가 유발되었다.According to the experimental investigation-induced experiments of the present inventors, when the eyes were closed for 2 weeks after hatching and reared for 6 weeks, the axial length of the eyes blocked with eyelid suture was 12.57 ± 0.67mm, which was more statistically than 12.03 ± 0.41mm in the control eye. There was a significant increase in academics and myopia was induced.

도파민(dopamine)은 척추동물 망막에 존재하는 망막의 주요한 신경 전달 물질로서 망막에 전달되는 광자극과 밀접한 관계가 있는 것으로 알려져 있고 광자극을 주면 도파민 합성의 필요한 효소인 타이로신 하이드록시라제(tyrosin hydroxylase)의 활성도가 증가하고 결국 망막내의 도파민 농도가 증가하고 다시 광자극을 차단하면 상기 효소의 활성고 감소의 도파민 농도의 감소를 다시 관찰할 수 있다.Dopamine is a major neurotransmitter of the retina in the vertebrate retina and is known to have a close relationship with photostimulation delivered to the retina, and when given photostimulation, tyrosin hydroxylase, a necessary enzyme for dopamine synthesis, is given. When the activity of, and eventually the dopamine concentration in the retina increases and again block photostimulation can be observed again the decrease in the dopamine concentration of activity and decrease of the enzyme.

본 발명자의 근시 유발 실험에서 안검 봉합안은 빛의 차단으로 타이로신 하이드록시라제의 활성도가 떨어지고 망막내 도파민 합성이 감소되어 성장이 촉진된 것으로 추정된다.In the myopia-induced experiment of the present inventors, the eyelid sutures are believed to promote the growth by blocking the light, reducing the activity of tyrosine hydroxylase and reducing dopamine synthesis in the retina.

또한 망막에는 도파민 수용기 1과 2(dopamine receptor 1 and 2 agonist)가 모두 존재하여 이 수용기에 의하여 작용이 조절된다.In addition, both dopamine receptors 1 and 2 agonists are present in the retina and their actions are regulated.

도파민 수용기가 2는 망막의 시 세포층에 존재하고 도파민 1은 시세포층에는 존재하지 않고 더 바깥층에 존재하며, 이 두 수용기가 작용시 효과도 다른 것으로 알려져 있다.Dopamine receptor 2 is present in the cell layer of the retina, and dopamine 1 is present in the outer layer rather than in the cell layer.

본 발명자의 도파민 수용기 2가 안구 성장에 필요한 역할을 할 것으로 생각되어 도파민 수용기 2 자극제를 성장기에 있는 안구의 근시 치료제로 사용하고져 한 것이며, 본 발명의 목적은 소아 근시에서 안경을 착용하여도 매년 연령 증가에 따라 근시가 증가하고 있어서 도파민 수용기 자극제(dopamine receptor agonist)를 근시 안구에 점안하여 안축장의 성장을 억제시키므로서 근시를 완전히 치료코져 한 것이다.The dopamine receptor 2 of the present invention is believed to play a necessary role in eye growth, and the dopamine receptor 2 stimulant is intended to be used as a myopic treatment for the ocular growth in the growing phase, and the object of the present invention is to age every year even when wearing glasses in pediatric myopia Myopia increases with increasing dopamine receptor agonist to myopic eye, which inhibits the growth of the axial axis, thereby completely treating myopia.

종래의 근시치료는 소아나 성인 모두 안경을 착용하는 방법이 사용되었으나, 소아에서는 안경을 착용하여도 계속해서 근시가 진행이 되어 별다른 치료효과를 올리지 못하였으며, 성인에서는 최초 수술요법으로 방사상 각막 절개술과 액시머 레이저 각막 절개술이 시행되고 있는 실정으로, 현재까지 소아의 근시치료제는 없는 형편이고 안경 착용을 하더라도 만 14세 까지는 계속 근시의 정도가 심해지고 있는 형편으로 현재까지 치료제는 전무한 상태에 있는 것이다.In the conventional myopia treatment, both children and adults used glasses, but in children, myopia progressed even after wearing glasses, which did not increase the therapeutic effect. Excimer laser keratectomy is currently being performed. Until now, children with myopia have not been treated and myopia continues to grow until the age of 14, even though wearing glasses.

본 발명은 이와 같은 종래 근시 치료에 있어서의 문제점을 해결하기 위하여 수년간의 연구개발 실험 끝에 근시치료제 개발에 성공한 것으로, 이하, 본 발명을 제조공정 및 실시예에 의하여 상세히 설명하면 다음과 같다.The present invention has succeeded in developing a myopia treatment after years of research and development experiments to solve the problems in the conventional myopia treatment, the present invention will be described in detail by the manufacturing process and examples as follows.

본 발명에서 근시를 유발시키는 방법은 본 발명자가 1991년 대한 안과 학회 제67차 학술대회에서 발표한 방법을 이용하였다.As a method of inducing myopia in the present invention, the method presented by the inventor at the 67th Conference of the Korean Ophthalmological Society in 1991 was used.

실시예 1Example 1

부화 2일된 동조의 병아리 36마리를 초음파(Ascan)을 이용하여 안축장 검사를 한후 6-0호 봉합사를 이용하여 우안의 안검을 봉합한후 자연 조명하에서 13일간 성장시킨후 우안의 안검을 풀고 초음파로 안축장을 측정하고 존절검사를 시행하니 안검 봉합한 눈의 안축장은 9.68±0.3㎜이고, 안검 봉합하지 않은 눈은 8.86±0.32㎜로서 안검 봉합한 눈(우안)이 안축장이 증가하였고 굴절검사시에도 근시가 유발되었다.A 36-day-old hatched chicks were examined using an ultrasound (Ascan), and then sutured to the right eye with a 6-0 suture, and then grown for 13 days under natural lighting. After measuring the axial length and performing the zone examination, the axial length of the closed eye was 9.68 ± 0.3mm, and the unopened eye was 8.86 ± 0.32mm. Was induced.

이후 다시 우안을 봉합하고 각각 18마리씩 두 군으로 나눈 후 각각 우안에 한군(실험군)에는 아포모르핀 안약을 매일 1일 2회점안하고, 다른군(대조군)의 우안에는 증류수만을 매일 1일 2회 점안한 다음 4주후에 각군 끼리 비교하였더니, 안축장이 실험군은 12±0.25㎜, 대조군은 12.93±0.67㎜로 아포모르핀 안약을 넣은 군이 현저히 안구 성장이 억제되고 굴절검사상 아모포르핀 만약을 점안한 눈에서는 점안전 5.25±0.75에서 점안 후 +0.25±0.93으로 근시의 치료효과가 탁월한 것으로 나타났다.Afterwards, the right eye was sutured and divided into two groups of 18 animals each. Then, one eye group (experimental group) used apomorphine eye drops twice a day, and the other eye group (control group) received only distilled water twice a day. Four weeks later, the groups were compared to each other, and the axial length was 12 ± 0.25 mm in the experimental group and 12.93 ± 0.67 mm in the control group. The point of safety was 5.25 ± 0.75 and + 0.25 ± 0.93 after instillation.

실시예 2Example 2

부화 2일된 동종의 병아리(Legporm) 36마리를 대상으로 실험군 18마리의 우안을 근시를 만들고 나머지 18마리의 우안은 대조군으로 한 다음, 실험군 우안에는 매일 0.025브로모크립틴 안약을 이 더 원시쪽으로 변하였다.Eighteen day-old chicks of the same day (Legporm) were hatched in 18 experimental eyes and the remaining 18 eyes were used as controls, and then 0.025 bromocriptine drops daily in the experimental eyes. It was.

예측되는 합병증으로 안압의 변화는 브로모크립틴 안약 투여안과 증류수 투연안, 그리고 정상안 사이에 통계학적으로 유의한 차이가 없었다.There were no statistically significant differences in intraocular pressure change between bromocriptine and distilled water and normal eyes.

따라서, 상기한 실시예에서와 같이 브로모크립틴(bromocriptine)을 안구에 점안하면 근시 안구에서 안축장의 증가를 억제시켜 근시치료에 탁월한 효과가 있음이 입증되었으며, 이러한 본 발명자의 연구실험 결과는 1992년 대한 안과 학회 제69차 학술대회 및 세계적으로 가장 권위있는 학회인 1993년도 미국안과 춘계학술대회 및 동 연구지(Investigative Ophthaslmology &Visual Science MARCH 15, 1993. VOL. 34 P 879)에 발표된 바가 있다.Therefore, as shown in the above embodiment, when bromocriptine was applied to the eye, it was proved that the myopic eye suppresses the increase of the axial length, thereby having an excellent effect on the treatment of myopia. The Korean Academy of Ophthalmology presented at the 69th Conference of the Korean Ophthalmological Society and the 1993 American Academy of Ophthalmology Spring Conference and Investigative Ophthaslmology & Visual Science MARCH 15, 1993. VOL. 34 P 879.

상술한 바와 같은 본 발명은 도파민 수용기 자극제인 아포모르핀과 브로모크립틴을 주원료료한 근시치료제를 제조하는 것을 특징으로 하고 있는 것으로서, 본 발명의 치료제를 근시안구에 점안할 경우 안축장의 성자을 억제시켜 근시 치료를 쉽게 할 수가 있으므로 종래 근시치료를 위해 안경을 착용하거나 각막 수술을 할 필요가 없이 간편한 방법으로 근시를 완치할 수 있는 매우 획기적인 발명인 것이다.As described above, the present invention is characterized in that a myopia treatment agent comprising apomorphine and bromocriptine, which are dopamine receptor stimulants, is used as a main ingredient. Since myopia can be easily treated, it is a very innovative invention that can cure myopia in a convenient manner without the need for wearing glasses or corneal surgery for conventional myopia treatment.
