Experiments with induced collagen arthritis

According to the method Strawich and Nimni Biochemistry, 10, 3905 (1971)/from bovine articular cartilage secrete collagen type II. Collagen is dissolved in acetic acid and stored at -20aboutC. Collagen type II was diluted to a concentration of 2 mg/ml and carefully emuleret in an equal volume of incomplete auxiliary substance Freund' a (NFW). The emulsion containing about 0.5 mg of collagen is injected into the injection Gia injected intradermally on day 0. Three times a week during the test, measure and record the volumes of the rear legs to identify the inflammatory response. Since day 1, the test group of animals receives the test compounds in the form of a suspension in carboxymethyl cellulose (medium) orally via a stomach tube, 5 days per week (Monday - Friday). Control animals receive the medium without the test compound. At the end of the test (day 28 or 30) in animals with cardiac puncture away the blood, in which the use of techniques with passive agglutination of red blood cells determine the level of antibodies to collagen anti-type II in serum, using treated with glutaraldehyde red blood cells sheep, to which collagen type II paired [Avrameas et al., Immunochemistry 6, 67 (1969); Andrio-poulos and other Arth. Rheum., 19, 613 613 (1976)]. Cellular signal or the delayed hypersensitivity type response to collagen type II is measured by radiometric ear indicator [Kostiala, Immunoloqy, 33, 561 (1967)]. In some cases, radiographs of the hind paws of two or three animals from each group determine bone damage caused by immunization with collagen type II and action of drugs. Injection NPV without collagen II is used to nematolosa (media).

The test results of the compounds of formula I in the system caused by collagen arthritis summarized in table. 4. % inhibition calculated by the following formula:

Vvis the volume of the hind legs of the animal treated with the carrier (carbomethoxyamino) and NFW without collagen II (negative control group).

The development of tests called auxiliary substance arthritis in rats.

The compounds were tested for the ability to change the swelling of the hind paws and bone damage that occurs in the result caused by the auxiliary substance edema in rats. With the aim to quantify the inhibition of swelling of hind paws in the result caused by the auxiliary substance arthritis made it defines two phases of inflammation: (1) primary and secondary in inyecciones the back foot and (2) secondary reinjections the back foot, which begins to develop after about 11 days after inducyruetsa activity. Cm. Chang, Arth. Rheum.,20, 1135-1141 (1977).

Called auxiliary substance induce arthritis in male rats race Lewis-Wistar (200-210 g) only peressini injection in the right hind paw with 0.1 ml of 0.5% suspension of killed heating liofilizovannyh Mycobacterium tuberculosis (Calbiochem-Perrigen-C) in mineral oil (modification of methods described in the paper by Winter et al., Arth. Rheum., 9, 394-397 (1966). One group of 10 rats ("TB-control) were subjected only to such processing. Another group of 5 rats was not processed (normal control). Each test compound suspended in carboxymethylcellulose (1% ) and administered orally to rats (groups of 5 rats) daily doses of 50 mg/kg, starting from the first day and 28 day after the injection of auxiliary substances (29 doses). Measure the feet by using a Statham pressure transducer' and a digital voltmeter with displacement of mercury. Volumes as injectionand and reinjection hind legs is measured in day 16, 18, 21, 23, 25, 28 and 30. On the 30th day off radiograph after sacrifice of the animals. Volume measurements injectionand feet, held from 16 days and 30, postpone using the computer for TV control, normal control and for animals, taking drugs is social control)/measure. The results obtained are summarized in table. 5.

It was also shown that the compounds of formula I prevent caused by ischemia cell damage, in particular damage to neuronal cells by the impact, as shown by the following test system.

Modeling of shock in rats

Kick in rats cause a blockage of the four arteries, which in the brain is blood, according to the following method. Male rats of Wistar race anaesthetize with metofane and placed in stereotoxic tool. On the dorsal surface of the neck make a longitudinal incision. Neck muscles are away, providing access to the dorsal surface of the spine. The two vertebral arteries reveal where they pass through the first cervical vertebra. Both arteries tightly sealed by the application of Elektroprivreda. After coagulation of the vertebral arteries of the rat is removed from stereotaxic instrument and the surgical wound is sutured. Then on the ventral surface of the neck make two longitudinal cuts. Reveal two common carotid artery and remove the surrounding nerves and connective tissue. Each carotid artery impose aromaticheski clip, made mainly from silicon trubecki clamp is designed that may be compressed with blocked carotid artery, if you pull a small thread of Celestica that comes out of the wound. Circulation to the brain via the carotid artery can be restored when the tension on the thread from elastica. After the surgery waiting 24 hours until the rats will Wake up.

On the day of the test compounds suspended in 2% Arabian gum and administered orally at different times before the induction stroke. The strokes (cerebral ischemia) causes compression around the carotid artery clamping for 30 minutes. During this time the rats, whose shot was successfully invoked lose reflex straightening and become insensitive to the stimulants. After 30 minutes of ischemia burden on the clamps removed with restoration of blood flow to the brain. Rats again allow connections on the morning after impact. On the third day after hitting animals given high dose barbiturate anesthetic and their brains poured in situ 10% neutral buffer formalin. After washing with aqueous formaldehyde in a quantity sufficient for fixation of the brain, the brain removed and stored in 10% formalin until the preparation of histological sections.

One of the areas of the brain most sensitive to induced ischemia on the, which remain insensitive within 30 min of ischemia, CA1pyramidal cell layer completely destroyed. This layer is examined under a microscope in histological sections prepared from hippocam. Brain damage graduate according to the following scale: - no damage, fully intact cell layer; 1 - slight damage to one-third of CA1layer destroyed; 2 - moderate damage, destroyed two-thirds of CA1layer; 3 - severe damage to the complete destruction of CA1layer.

With the aim of obtaining an accurate picture of the damage investigated corruption in 10-12 slices from each brain. Average damage count for each group. Indicators for animals treated with compounds compared statistically with the figures for the control group who received only the vehicle (2% Arabian gum), which was used for the suspension of the compounds. The level of significance determined using t-criterion of student. The results obtained are summarized in table. 6.
