Definitions
- the invention relates to the production of a colorant for staining cells in the human or animal body.
- trypan blue As the dye.
- This compound which is known from the class of diazo dyes, is used in an aqueous solution for coloring the front capsule for cataract surgery on the eye. By visualizing the anterior capsule, the surgeon recognizes the outline of the capsulorxis, which makes phacoemulsification easier.
- Trypan blue is a cytotoxic substance, such as from Solomon K.D. et al .: Protective effect of the anterior lens capsule during extra-capsular cataract extraction, OPHTHALMOLOGY, vol. 96, no. 5, May 1989 (1989-05), 591-597 and Veckener M. et al .: Ocular toxicity study of trypan blue injected into the vitreous cavity of rabit eyes, Graefe's Arch Clin Ex Ophthalmol (2002) 239: 698- 704 is known.
- trypan blue it is therefore necessary to rinse out the eye area in particular, in which the trypan blue has been used as a colorant, immediately after the cataract surgery, in order to avoid a longer stay in the body or in the eye.
- the object of the invention is to provide a dye with a lack of cytotoxicity which is suitable for the visualization of membranes with a limiting or separating function or of membranes formed by disease in the human or animal body.
- the use of a non-vital dye and biocompatible dye in a physiologically compatible aqueous solution of in particular sodium chloride, which is adjusted to a pH of 6.8 to 7.8, in particular about 7.4, with a buffer can, a colorant for staining cells, in particular separating or delimiting membranes in the human and animal body created.
- the coloring agent is a non-polymeric, low molecular weight, water-soluble dye. That with the invention Single colorants used can be used for vitality testing, but in contrast to conventional vital dyes, the biocompatible dye used in the invention can be used to color the living cells in addition to the dead cells to distinguish them from the living material.
- a triphenylmethane dye is preferably used as a water-soluble, low molecular weight dye.
- the dye is used without a carrier.
- suitable dyes are patent blue and brilliant blue R, the latter being known from protein staining in gel electrophoresis.
- a phosphate, hydrogen carbonate or citrate buffer the pH of which can be adjusted using sodium hydroxide, can be used as the buffer.
- concentration of the bioco-patible dye, e.g. of patent blue V in water solution is preferably 0.6 to 2.5 g / 1, in particular approximately 1.2 g / 1.
- a spontaneous coloring of the desired areas in the human or animal body is achieved.
- the colorant can be used to stain the lens capsule, in particular the lens capsule during cataract surgery.
- the staining takes place before the capsulorxis and phacoemulsification.
- the aqueous humor is sucked out through a corneal or scleral tunnel incision and the anterior chamber is then filled with a gas, especially air.
- a gas especially air.
- colorant solution eg from Patent Blue V
- the lens capsule is colored, which is limited by the pupil edge of the iris.
- the front chamber is rinsed out with a sodium chloride solution to wash out the dye that is not required.
- a viscoelastic solution is then introduced into the anterior chamber of the eye in a conventional manner in order to carry out the cataract operation. Due to the blue discoloration of the anterior capsule, the outline of the capsulor exis is clearly visible and can be clearly distinguished from the gray tissue of the lens nucleus.
- the coloring agent can be used to stain the internal membrane or, for example, as a result of PVR (proliferative vitreoretinopathy) membranes, in particular epiretinal membranes on the retina or on the back surface of the vitreous border membrane, in particular in retinal and vitreous surgery ,
- PVR proliferative vitreoretinopathy
- the dye for example patent blue V
- the membrane When removing, for example, an epiretinal membrane from the retina, the dye, for example patent blue V, is brought selectively to the membrane to be removed in about 0.3 ml of the specified buffer solution with the aid of a cannula entering via the pars plana.
- the vitreous can be completely or partially replaced beforehand by a gas filling, as is conventionally used in vitreous or retinal, in particular macular, surgery.
- a gas filling as is conventionally used in vitreous or retinal, in particular macular, surgery.
- the adjacent retinal tissue can be stained with a weaker degree of staining.
- the membrane is removed from the underlying, non-stained retinal tissue, a good contrast is then obtained. After staining excess colorant solution is rinsed out and the empty space is filled with the gaseous vitreous substitute mentioned.
- the coloring makes it possible to work with a non-illuminated or only weakly illuminated instrument when removing the membrane. As a result, the light toxicity is considerably reduced with sufficient contrast perception.
- ⁇ menhang with epiretinal membranes epiretinal gliosis, "ma cular pucker", “surface wrinkling" is a valuable aid in searching and removal of the membranes.
- a viscoelastic material for example hyaluronic acid
- a viscoelastic aid in relation to the intraocular tissue, in particular the iris of the eye and the fundus reflex, during the cataract operation.
- the biocompatible solution according to the invention for example of patent blue V or brilliant blue R, has no cytotoxicity.
- mouse cells L 929 and ARPE-19 cells were treated in the incubator with the dye blue V according to the invention at different concentrations over 68 to 72 hours.
- the vitality of the cells and a derived cytotoxicity are quantified by determining the protein content of the treated cell cultures compared to untreated control cultures. The protein content is determined colorimetrically using a standard method.
- the invention proves to be particularly advantageous when performing cataract operations with dense cataracts and / or heavily pigmented fundi, in which the fundus reflex is only weakly developed or absent. With the help of the coloring agent, a good contrast can be achieved between the colored front capsule and the underlying tissue.
- Patent blue V with a concentration of 1.2 g / 1 in one
- Phosphate buffer solution 200 ml solution contain: 0.240 g patent blue V
- Example 2 Patent blue V with a concentration of 1.2 g / 1 in a hydrogen carbonate buffer solution.
- 200 ml solution contain: 0.240 g patent blue V 0.420 g sodium bicarbonate (NaHC0 3 ) 1.640 g sodium chloride (NaCl) sodium hydroxide for pH adjustment
- Patent blue V with a concentration of 1.2 g / 1 in a citrate buffer solution.
- 200 ml solution contain: 0.240 g Patent Blue V
- Identical embodiments according to Examples 1, 2 and 3 can also be produced with brilliant blue R at a concentration of 1.2 g / 1.
- the pH of the buffer solutions is preferably adjusted using sodium hydroxide. However, it is also possible to adjust the solution itself to the desired pH (neutral, slightly acidic, slightly alkaline) within the preferred range from 6.8 to 7.8.
- the concentration of patent blue is preferably set to 0.6 to 2.5 g / 1, in particular approximately 1.2 g / 1, by means of a corresponding amount of patent blue V.
