Description

Fremgangsmåte til fremstilling av ledeskinner av menneskelig Method for the production of human guide rails

eller dyrisk vev til gjenopprettelse av beskadigede eller ødelagte spesifikke vevdeler i den menneskelige og dyriske kropp. or animal tissue for the restoration of damaged or destroyed specific tissue parts of the human and animal body.

Ved Ødeleggelser av enhver type på den menneskelige In case of damage of any kind to the human body

kropp, spesielt ved kompliserte frakturer, skudd-, snitt- eller stikkødeleggelser av muskulatur, kan ofte de regionale nerver be-skadiges eller delvis ødelegges. Herved får de distale kroppsdeler ved beskadigelsen, spesielt ekstremitetene, ikke nerveimpulser, således at det kan oppstå lammelser. Når små defekter oppstår på nerve-ledningene, så er det riktignok mulig å sy nerveendene mot hverandre og således reparere defektene; ved stofftap og dermed forbundne lange brudd av nervevevet er imidlertid nerveskadene ikke reparer-bare og medfører lammelser. body, especially in the case of complicated fractures, gunshot, cut or stab destruction of musculature, the regional nerves can often be damaged or partially destroyed. As a result, the distal body parts of the damage, especially the extremities, do not receive nerve impulses, so that paralysis can occur. When small defects occur on the nerve cords, it is certainly possible to sew the nerve ends together and thus repair the defects; however, in the case of substance loss and associated long breaks in the nerve tissue, the nerve damage is not repairable and leads to paralysis.

Overraskende og med forbausende resultater har man nå funnet at det er mulig med en vidtgående restituering ved stofftap av nerveledninger, når man binder sammen de defekte steder ved hjelp av en såkalt ledeskinne. De som ledeskinner tjenende vev-preparater fremstilles etter følgende fremgangsmåte: Surprisingly and with amazing results, it has now been found that it is possible to make extensive restitution in case of material loss of nerve cords, when the defective places are tied together with the help of a so-called guide rail. The tissue preparations serving as guide rails are produced according to the following procedure:

På menneske- eller dyrelik utprepareres kort etter døden Human or animal corpses are prepared shortly after death

de ønskede spesifikke vevsdeler, f.eks. nerver, spesielt for ytre ekstremiteter, og innlegges umiddelbart i høykonsentrert kok-saltoppløsning for konservering og desenzymatisering. Deretter spyles de med rennende vann omtrent 1 time, og behandles to ganger, hver gang ca. 24 timer, med en ca. 2-6%-ig, fortrinnsvis 5%-ig hydro-genperoksydoppløsning. Denne behandling har det formål å utløse korpuskulære bloddeler og plasma fra blod- og lymfkapillarene. Ved denne prosess finner det på grunn av det frigjorte oksygen sted en sterk skumdannelse. Ved gassdannelsen økes vevets mellomvev og vevet løsnes derved. the desired specific tissue parts, e.g. nerves, especially for the outer extremities, and immediately placed in highly concentrated saline solution for preservation and de-enzymatisation. They are then rinsed with running water for approximately 1 hour, and treated twice, each time approx. 24 hours, with an approx. 2-6%, preferably 5% hydrogen peroxide solution. This treatment aims to release corpuscular blood parts and plasma from the blood and lymph capillaries. During this process, due to the liberated oxygen, a strong foam formation takes place. During the formation of gas, the interstitium of the tissue is increased and the tissue is thereby loosened.

Etter hydrogenperoksydbehandlingen etterspyles først ved lav temperatur med strømmende vann og deretter spyles det med av-kjølt destillert vann inntil spylevannet er klart. I tilknytning hertil dypkjøles de sterkt vannede nervepreparater langsomt, fordel-aktig inntil -2 5°C. I løpet av denne dypkjøling kommer det til krystallisasjon av den vandige vevsvæske og derved til dannelse og økning av ytterligere vevsspalter. Umiddelbart etter dypkjølingen lyofiliseres preparatene, dvs. ved høyt vakuum fordampes vannet langsomt og vevet tørkes i denne tilstand. Denne lyofilisering har til formål å bevare vevet i den ved ovennevnte behandling tilveiebragte struktur og utelukke en forhorning, således at man etter tørkingen får et med mange mellomvev utstyrt, løst nervevev. After the hydrogen peroxide treatment, first rinse at a low temperature with running water and then rinse with cooled distilled water until the rinse water is clear. In connection with this, the highly watered nerve preparations are deep-cooled slowly, beneficially, down to -25°C. During this deep cooling, crystallization of the watery tissue fluid occurs and thereby the formation and increase of further tissue clefts. Immediately after deep cooling, the preparations are lyophilized, i.e. under high vacuum, the water slowly evaporates and the tissue is dried in this state. The purpose of this lyophilization is to preserve the tissue in the structure provided by the above-mentioned treatment and to exclude keratinization, so that after drying you get a loose nerve tissue equipped with many interstitial tissues.

For klinisk bruk steriliseres deretter preparatene under vakuum enten i glasskår med etylenoksyd og oppbevares deretter i vakuum, eller man innsveiser preparatene i en med aluminium kasjert polyetylenpose og steriliserer ved hjelp av gammastråler ved anvendelse av en dosis på 2,5 Mrad. Preparatet er således ved kjølings-lagring omtrent ubegrenset holdbart og kan stadig bruksferdig og sterilt stilles til disposisjon for nevrologer eller kirurger. Preparatets applikasjon foregår på følgende måte: Er det ved en gammel eller frisk nerveskade fastslått en defekt ved nervesubstansen som ikke er reparerbar ved hjelp av en nervesøm, så friskgjøres de to adskilte nerveender proximalt og distalt og eventuelt tilstedeværende fibromer fjernes. Etter at preparatet er tatt sterilt ut av den sterile pakning og rehydrati-sert ved 30 til 60 minutters innlegning i sterilt aqua bidestillat, påsys de dannede åpninger topp til topp med et tilsvarende stort stykke av nervepreparatet fremstilt etter ovennevnte beskrivelse. For clinical use, the preparations are then sterilized under vacuum either in shards of glass with ethylene oxide and then stored in a vacuum, or the preparations are sealed in a polyethylene bag lined with aluminum and sterilized using gamma rays using a dose of 2.5 Mrad. The preparation thus has an almost unlimited shelf life when refrigerated and can always be made available to neurologists or surgeons sterile and ready for use. The application of the preparation takes place in the following way: If, in the case of old or fresh nerve damage, a defect has been established in the nerve substance that cannot be repaired with the help of a nerve suture, then the two separated nerve ends proximally and distally are healed and any fibroids present are removed. After the preparation has been removed sterilely from the sterile package and rehydrated by placing it in sterile aqua bidistillate for 30 to 60 minutes, the openings formed are covered top to top with a correspondingly large piece of the nerve preparation prepared according to the above description.

Ved hjelp av det osmotiske og onkotiske fall som består mellom nervepreparatets vanninnhold og kroppens vevsvæske, finner det sted en utveksling av vevsvann fra nervepreparatet med kroppens egen vevsvæske, hvorved kroppens egen vevsvæske trenger inn i de ved ovennevnte fremgangsmåte tilveiebragte hulrom i preparatet. Ut fra kroppens egne nerveender danner det seg nå nye nervesprosser som ved værelsestemperatur og under de tilveiebragte optimale vekst-betingelser kan vokse inn i det løse, med egen kroppsvæske gjennom-trengte nervevev. De benytter derved vevstrukturen av nervepreparatet på samme måte som ledeskinner. With the help of the osmotic and oncotic drop that exists between the nerve preparation's water content and the body's tissue fluid, an exchange of tissue water from the nerve preparation with the body's own tissue fluid takes place, whereby the body's own tissue fluid penetrates into the cavities in the preparation provided by the above-mentioned method. From the body's own nerve endings, new nerve sprouts now form which, at room temperature and under the optimal growth conditions provided, can grow into the loose nerve tissue permeated with the body's own fluid. They thereby use the tissue structure of the nerve preparation in the same way as guide rails.

Denne innvoksing av nye nerveceller foregår såvel fra den proximale som fra den distale ende og fører, slik kliniske forsøk har vist, f.eks. ved en ca. 5 cm lang bro etter 5 til 6 måneder, til sammenvoksing av nervecellene og dermed til gjenopprettelse av lede-og funksjonsevnen av den distale nerve. This ingrowth of new nerve cells takes place both from the proximal and from the distal end and leads, as clinical trials have shown, e.g. at an approx. 5 cm long bridge after 5 to 6 months, to fuse together the nerve cells and thus to restore the conduction and functional ability of the distal nerve.

Tilsvarende restitusjonseffekter ble også fastslått ved tilsvarende anvendelse av således preparerte homologe og delvis også heterologe vev for utøvelse av en ledeskinnefunksjon for ny-dannelse av vev ved fascier-, dura-, sene- og bruskvev. Corresponding restitution effects were also determined by the corresponding use of thus prepared homologous and partly also heterologous tissues for the exercise of a guide rail function for new tissue formation in fascia, dura, tendon and cartilage tissue.
