Definitions
- the present invention relates to a therapeutic agent for corneal disorders containing interleukin-16 as an active ingredient. Background technology
- interleukin-16 is an important bioactive factor involved in the immune system, hematopoietic system and the like.
- interleukin-16 is useful as a therapeutic agent for corneal disorders. Disclosure of the invention
- the present invention relates to a therapeutic agent for corneal disorders containing interleukin-16 as an active ingredient.
- a corneal disorder is one in which the cornea is damaged by various factors such as corneal ulcer, corneal epithelial detachment, keratitis, and dry eye, and various drugs have been studied as therapeutic agents therefor.
- the present inventor focused on interleukin-16, which is a physiologically active substance, Its effect on corneal disorders was studied.
- interleukin-16 clearly expands the corneal epidermal cell layer compared to the control group, and the corneal wound heals faster. This demonstrated that interleukin-16 is useful as a therapeutic agent for corneal disorders.
- the therapeutic agent for corneal disorders of the present invention is preferably administered topically, particularly as an eye drop.
- the concentration of interleukin-16 in the ophthalmic solution may be set according to symptoms, age, etc., and is not particularly limited, but is preferably 0.000001 to 1%.
- the dosage may be 1 to several drops at a time, and once to several times a day.
- dissolvable eye drops and eye ointments may be used.
- isotonic agents such as sodium chloride and potassium chloride, and buffers such as sodium hydrogen phosphate and sodium dihydrogen phosphate Agents, stabilizing agents such as sodium edetate, preservatives such as ethylparaben, butylparaben, and benzalkonium chloride; pH adjusting agents such as sodium hydroxide, diluted hydrochloric acid, white petrolatum, and liquid paraffin Additives such as a base for ophthalmic ointment may be added as necessary, and the preparation may be made by a conventional method.
- isotonic agents such as sodium chloride and potassium chloride, and buffers such as sodium hydrogen phosphate and sodium dihydrogen phosphate Agents, stabilizing agents such as sodium edetate, preservatives such as ethylparaben, butylparaben, and benzalkonium chloride; pH adjusting agents such as sodium hydroxide, diluted hydrochloric acid, white petrolatum, and liquid paraffin Additives such
- Interleukin-16 is contained in 100 ml of 0. OOOOlg, 0.00003 g, 0. OOOlg, 0.0005 g, 0. OOlg, 0.005 g, 0.05 g, O.lg in 100 ml each as in Formulation 1.
- Ophthalmic solution can be obtained.
- Formula 2 1 0 0 m 1
- interleukin-16 is useful in treating corneal disorders.
- the method was performed according to the method of Nishida et al. (The Journal of Cell Biology, 97, 1653 (1983)) using the cornea of a male Japanese white egret weighing 2.Q to 3.0 kg.
- corneal epithelial cells were clearly expanded in the cultures containing interleukin-16 as compared with the control, and the effect was not significant.
- Table 1 corneal epithelial cells were clearly expanded in the cultures containing interleukin-16 as compared with the control, and the effect was not significant.
- Corneal epithelial detachment was induced with n-heptanol using male Japanese white egrets weighing 2.0 to 3. Okg (7 birds per group: 14 eyes), and fluorescein staining was performed immediately after detachment, and corneal photographs were taken. .
- Intraleukin-16 was dissolved in a base [PBS (-)], and the base was instilled four times a day (501Z times) for two days at 2-hour intervals as a control. Twenty-four hours after detachment, fluorescein staining was performed, and a photograph of the cornea was taken. The corneal wound area was calculated by measuring the fluorescein-stained area of the cornea photographed using an image analysis processing system [trade name: Cosmo Zone 1S, Nikon Corporation].
- Table 2 shows the wound area (%) 24 hours after the corneal epithelium detachment was defined as 100.
- the present invention provides a therapeutic agent for corneal disorder containing interleukin-16 as an active ingredient.
