Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by progressive joint inflammation, resulting in cartilage destruction and bone erosion. It was reported that low-dose radiation modulates immune disease. Here, we investigated whether low-dose whole-body irradiation has preventive and therapeutic effects in collagen-induced RA (CIA) mouse models. Fractionated low-dose irradiation (0.05 Gy/fraction, total doses of 0.1, 0.5 or 0.8 Gy) was administered either concurrently with CIA induction by Type II collagen immunization (preventive) or after CIA development (therapeutic). The severity of CIA was monitored using two clinical parameters, paw swelling and redness. We also measured total Immunoglobulin G (IgG) and inflammatory cytokines (interleukine (IL)-6, IL-1β and tumor necrosis factor-alpha (TNF-α)) in the serum by enzyme-linked immunosorbent assay, and we evaluated histological changes in the ankle joints by immunohistochemistry and hematoxylin and eosin staining. Low-dose irradiation reduced CIA clinical scores by up to 41% in the preventive model and by 28% in the therapeutic model, while irradiation in the preventive model reduced the typical CIA incidence rate from 82 to 56%. In addition, low-dose irradiation in the preventive model decreased total IgG by up to 23% and decreased IL-1β and TNF-α by 69 and 67%, and in the therapeutic model, decreased total IgG by up to 35% and decreased IL-1β and IL-6 by 59 and 42% with statistical significance (P < 0.01, 0.05 and 0.001). Our findings demonstrate that low-dose radiation has preventive and therapeutic anti-inflammatory effects against CIA by controlling the immune response, suggesting that low-dose radiation may represent an alternative therapy for RA, a chronic degenerative immune disease.

Abstract
Rheumatoid arthritis (RA) is an inflammatory disease mainly affecting synovial joints. Photobiomodulation through low-level laser therapy (LLLT) and resistance exercise may improve the inflammatory process. Therefore, we analyzed the effects of resistance exercise, LLLT, and the combination of both treatments on hind paw grip strength and ankle joint histomorphometric aspects of Wistar rats subjected to experimental RA. A total of 64 male Wistar rats were divided into eight groups: control, control LLLT, control exercise, control LLLT and exercise, arthritis, arthritis LLLT, arthritis exercise, and arthritis LLLT and exercise groups. The experimental RA was induced by a complete Freund's adjuvant injection into the knee joint cavity. Climbing exercises and LLLT (660 nm; 5 J/cm2 per point) were performed as the treatment. In addition, muscle strength was evaluated using the grip strength test, and morphometric evaluations were performed on the ankle joint. Generalized mixed models and multivariate analysis of variance tests were used for statistical analysis. Statistical significance was set at a p-value of .05. Arthritis LLLT, exercise, and LLLT and exercise had positive effects on grip strength between the groups (F[7.56] = 5.8, p < .004) and within the groups (F[4.3] = 9.9, p < .002) throughout the evaluations. Morphometry revealed degenerative lesions in the ankle joint as subintima with angiogenesis, inflammatory cells, flocculated articular cartilage, chondrocyte disorganization, and pannus in the arthritis group (p < .001). The treated groups exhibited morphological characteristics similar to those of the control group. LLLT and resistance exercise restored muscle strength and morphological aspects of the ankle joint in rats with experimentally induced RA.

Abstract
The development of collagen type II (CII)-induced arthritis (CIA), a model of rheumatoid arthritis, in rats housed in cages with bedding composed of Celliant fibres containing ceramic particles, which absorb body heat and re-emit the energy back to the body in the form of infrared radiation (+IRF rats), and those housed in cages with standard wooden shaving bedding (-IRF control rats) was examined. The appearance of the first signs of CIA was postponed, while the disease was milder (judging by the arthritic score, paw volume, and burrowing behaviour) in +IRF compared with -IRF rats. This correlated with a lower magnitude of serum anti-CII IgG antibody levels in +IRF rats, and lower production level of IL-17, the Th17 signature cytokine, in cultures of their paws. This could be partly ascribed to impaired migration of antigen-loaded CD11b + dendritic cells and their positioning within lymph nodes in +IRF rats reflecting diminished lymph node expression of CCL19 /CCL21. Additionally, as confirmed in rats with carrageenan-induced paw inflammation (CIPI), the infrared radiation from Celliant fibres, independently from immunomodulatory effects, exerted anti-inflammatory effects (judging by a shift in pro-inflammatory mediator to anti-inflammatory/immunoregulatory mediator ratio towards the latter in paw cultures) and ameliorated burrowing behaviour in CIA rats.

Abstract
The aim of this study was to evaluate the effects of low-level laser therapy using the gallium arsenide laser (λ = 830 nm) on the articular cartilage (AC) organization from knee joint in an experimental model of microcrystalline arthritis in adult male Wistar rats. Seventy-two animals were divided into three groups: A (control), B (induced arthritis), and C (induced arthritis + laser therapy). The arthritis was induced in the right knee using 2 mg of Na4P2O7 in 0.5 mL of saline solution. The treatments were daily applied in the patellar region of the right knee after 48 h of induction. On the 7th, 14th, and 21st days of treatment, the animals were euthanized and their right knees were removed and processed for structural and biochemical analysis of the AC. The chondrocytes positively labeled for the TUNEL reaction were lower in C than in B on the 14th and 21st days. The content of glycosaminoglycans and hydroxyproline in A and C was higher than B on the 21st day. The amount of tibial TNF-α in B and C was lower than in A. The amount of tibial BMP-7 in B and C was higher than in A. The femoral MMP-13 was lower in B and C than for A. The tibial TGF-β for C was higher than the others. The femoral ADAMT-S4 content of A and C presented similar and inferior data to B on the 21st day. The AsGa-830 nm therapy preserved the content of glycosaminoglycans, reduced the cellular changes and the inflammatory process compared to the untreated group.

Abstract
AIMS To investigate the effect of low-level laser therapy (LLLT) on experimentally induced inflammation in retrodiscal tissues of the rabbit temporo?mandibular joint (TMJ) using scintigraphic imaging. METHODS Eleven male New Zealand rabbits were included in this study. Six randomly selected rabbits were imaged to provide normal joint images (normal group) before the initiation of the experiment. A 5% formalin solution was locally injected into both right and left TMJs of all rabbits. Subsequently, Ga-Al-As laser (wavelength: 815 nm; energy density: 12 J/cm2; output power: 250 mW) was applied for 48 seconds. The treatment was performed six times for 2 weeks to the left TMJ of all rabbits. The right TMJs of the rabbits were used as the control (nontreated) TMJ group, while left TMJs were used as the treated TMJ group. Static images of TMJ were taken at 24 hours, 7 days, and 14 days after the beginning of the treatment. The images of all TMJs were taken in the posteroanterior direction with the rabbit under sedation and its mouth open. The Mann-Whitney U test was used to compare group differences, and intragroup differences were determined by the Friedman test and Wilcoxon sign test. RESULTS Significant differences were found between normal and both the control and treated TMJ groups. A reduction of inflammation in both treated and control TMJ groups was obtained, but there was no statistically significant difference between the groups. CONCLUSION Under the conditions used in this study, quantitative scintigraphic measurements of TMJ inflammation of the treated TMJ group decreased but did not differ significantly from those of the control TMJ group.

Abstract
PURPOSE Low-dose radiotherapy (LD-RT) of arthritic joints applied during the peak of the acute inflammatory response improves the clinical and histomorphological development of adjuvant arthritis. The study was undertaken to investigate the cellular composition of the inflammatory infiltrate and the expression of the pro-inflammatory and anti-inflammatory enzymes, inducible nitric oxide synthase (iNOS), cyclo-oxygenase 2 (COX-2) and haem-oxygenase 1 (HO-1), in response to LD-RT. MATERIALS AND METHODS Adjuvant arthritis in female Lewis rats was induced by intradermal injection of heat-inactivated mycobacterium tuberculosis on day 0. Both arthritic hind paws were sham irradiated (group 1) or X-irradiated with either 5 x 1.0 Gy (group 2) or 5 x 0.5 Gy (group 3) from days 15 to 19 after induction (15 animals/group). On days 21 (n=12 joints/group) and 30 (n=18 joints/group), cryostat sections were analysed histologically and immunohistologically after specific staining for macrophages, iNOS, COX-2 and HO-1. RESULTS A total of 5 x 1.0 Gy or 5 x 0.5 Gy led to a significant reduction of clinical symptoms from days 21 to 29, and a highly significant reduction of cartilage and bone destruction on day 30. Macrophage-positive areas could be detected continuously throughout the periarticular infiltrate, and were slightly reduced after LD-RT on days 21 and 30. This reduction was more pronounced after 5 x 1.0 Gy. Following LD-RT, the iNOS score was reduced by about 45-50% on days 21 (p<0.05) and 30 (p<0.001). In contrast, the HO-1 score was increased by about 50% on days 21 (p=0.08) and 30 (p=0.03). CONCLUSIONS The clinically and histologically observed prevention of the progression of adjuvant arthritis after LD-RT given during the peak of the acute inflammatory response and the reduction of cartilage and bone destruction in the chronic phase appears to be related to the modulation of iNOS activity by low X-ray doses.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disorder affecting 1% of the population worldwide. Pulsed electromagnetic field (PEMF) has a number of well-documented physiological effects on cells and tissues including antiinflammatory effect. This study aims to explore the antiinflammatory effect of PEMF and its possible mechanism of action in amelioration of adjuvant induced arthritis (AIA). Arthritis was induced by a single intradermal injection of heat killed Mycobacterium tuberculosis at a concentration of 500 microg in 0.1 ml of paraffin oil into the right hind paw of rats. The arthritic animals showed a biphasic response regarding changes in the paw edema volume. During the chronic phase of the disease, arthritic animals showed an elevated level of lipid peroxides and depletion of antioxidant enzymes with significant radiological and histological changes. Besides, plasma membrane Ca(2+) ATPase (PMCA) activity was inhibited while intracellular Ca(2+) level as well as prostaglandin E(2) levels was noticed to be elevated in blood lymphocytes of arthritic rats. Exposure of arthritic rats to PEMF at 5 Hzx4 microT x 90 min, produced significant antiexudative effect resulting in the restoration of the altered parameters. The antiinflammatory effect could be partially mediated through the stabilizing action of PEMF on membranes as reflected by the restoration of PMCA and intracellular Ca(2+) levels in blood lymphocytes subsequently inhibiting PGE(2) biosynthesis. The results of this study indicated that PEMF could be developed as a potential therapy for RA in human beings.

Abstract
Studies were undertaken to find out the effects of low frequency pulsed electromagnetic field (PEMF) in adjuvant induced arthritis (AIA) in rats, a widely used model for screening potential therapies for rheumatoid arthritis (RA). AIA was induced by an intradermal injection of a suspension of heat killed Mycobacterium tuberculosis (500 mug/0.1 ml) into the right hind paw of male Wistar rats. This resulted in swelling, loss of body weight, increase in paw volume as well as the activity of lysosomal enzymes viz., acid phosphatase, cathepsin D, and beta-glucuronidase and significant radiological and histological changes. PEMF therapy for arthritis involved optimization of three significant factors, viz., frequency, intensity, and duration; and the waveform used is sinusoidal. The use of factorial design in lieu of conventional method resulted in the development of an ideal combination of these factors. PEMF was applied using a Fransleau-Braunbeck coil system. A magnetic field of 5 Hz x 4 muT x 90 min was found to be optimal in lowering the paw edema volume and decreasing the activity of lysosomal enzymes. Soft tissue swelling was shown to be reduced as evidenced by radiology. Histological studies confirmed reduction in inflammatory cells infiltration, hyperplasia, and hypertrophy of cells lining synovial membrane. PEMF was also shown to have a membrane stabilizing action by significantly inhibiting the rate of release of beta-glucuronidase from lysosomal rich and sub-cellular fractions. The results indicated that PEMF could be developed as a potential therapy in the treatment of arthritis in humans.

Abstract
BACKGROUND AND PURPOSE Low-dose radiotherapy is widely accepted as a very effective treatment option for inflammatory symptoms associated with painful degenerative joint disorders. Radiation doses and fractionation schedules in practical use are empirical and mainly based on clinical observations. Experimental data are rare. The efficacy of low-dose X-irradiation on adjuvant induced arthritis in rats using different fractionation schemes was investigated in vivo, in order to explore whether there is a dose and fractionation dependence. MATERIAL AND METHODS Adjuvant arthritis in female Lewis rats (n = 128) was induced by intradermal injection of heat-inactivated Mycobacterium tuberculosis on day 0. Both arthritic hind paws were sham-irradiated (group 1: days 10-14; group 2: days 15-19; group 3: days 22-26) or X-irradiated with either 5 x 1.0 Gy (group 4: days 10-14; group 6: days 15-19; group 8: days 22-26; group 10: days 10, 12, 14, 16, and 18) or 5 x 0.5 Gy (group 5: days 10-14; group 7: days 15-19; group 9: days 22-26; group 11: days 10, 12, 14, 16, and 18; group 12: days 10-14 and 22-26). The clinical parameters arthritis score (AS), hind paw volume (HPV), and body weight were determined. RESULTS A significant decrease of the clinical arthritis parameters was observed following 5 x 0.5 Gy or 5 x 1.0 Gy during the acute maximum of the inflammatory response (days 15-19). The most pronounced treatment effect was reached after two daily fractionated series of 5 x 0.5 Gy with an early treatment onset (days 10-14) and repetition in interval (days 22-26). After the application of 5 x 1.0 Gy on days 10-14 or in a protracted scheme (days 10, 12, 14, 16, and 18), only a nonsignificant positive trend could be detected. Daily fractionated X-irradiation in the chronic phase of adjuvant arthritis (days 22-26) did not show any positive clinical effect. CONCLUSION Low-dose radiotherapy is able to prevent a full-blown arthritic reaction if given during the florid phase of adjuvant arthritis. Two series of 5 x 0.5 Gy with an early treatment onset (days 10-14) and repetition in interval (days 22-26) were the most effective treatment schedule in this experimental study.

Abstract
Radiation synovectomy is one of the most useful methods for treating patients with refractory synovitis because of its convenience, long-term effects, repeatability and the avoidance of surgery. In this study, we investigated the toxicity, stability and biodistribution of a rhenium-188 (188Re)-tin colloid to evaluate its suitability as a synovectomy agent. Twenty four hours after injecting the 188Re-tin colloids (74 KBq/0.1 mL) into the tail vein of ICR mice, most of the 188Retin colloidal particles was found in the lungs. In addition, there were no particle size changes at either room temperature or at 37 degrees C after injecting the 188Re-tin colloids in human plasma and synovial fluid. In vitro stability tests showed that the 188Re-tin colloid remained in a colloidal form without a critical size variation over a 2-day period. We investigated the leakage of 188Retin colloids from the intraarticular injection site with gamma counting in New Zealand white rabbits. The 188Re-tin colloids (55.5 MBq/0.15 mL) were injected at the cavum articular and the mean retention percentage of the 188Re-tin colloid was 98.7% for 1 day at the injection site, which suggests that there was neither change in the particle size nor leakage at the injection sites. In the biodistribution study with the SD rats, the liver showed the highest radioactivity (0.0427% ID/organ) except for the injected knees (99.49%). In the SD rats, mild toxicities including the skin or a synovium inflammation were observed as a result of a radioactivity of 15 mCi/kg at the intraarticular injection site. However, there was no systemic toxicity. In the Ovalbumin (OVA)-induced arthritic rabbits, the 188Re-tin colloid improved the macroscopic, the histological score and reduced the knee joint diameter when compared to the arthritic control. In conclusion, a 188Re-tin-colloid is considered as a strong candidate for radiation synovectomy with a superior efficacy and safety.

PURPOSE Low-dose radiotherapy (LD-RT) with single fractions between 0.1 and 1.0 Gy is known to exert an antiinflammatory effect. Although different mechanisms for the clinical efficiency were proposed, only few experimental data are still available. This paper focuses on functional and molecular aspects of LD-RT. METHODS AND RESULTS The antiinflammatory efficiency of LD-RT in clinical studies could be confirmed in experimental models of osteoarthritis and rheumatoid arthritis. In a model of adjuvants arthritis, 5 x 1.0 Gy as well as 5 x 0.5 Gy, given at the maximum of the acute inflammation, could prevent clinically and histologically progression of the disease without affecting existing signs of inflammation. The effect of LD-RT on the adhesion of peripheral blood mononuclear cells (PBMC) and endothelial cells (EC) was analyzed in in-vitro assays. In the dose range between 0.3 and 0.7 Gy almost 4 hours after irradiation adherent cells reached a relative minimum of adhesion compared to unirradiated controls. In PBMC an discontinuous increase of apoptosis with a maximum between 0.3 and 0.5 Gy, the proteolytic shedding of L-selectin and an increased expression of the antiinflammatory cytokine interleukin 10 as well as downregulation of TNF alpha could be identified as potential mechanisms for the observed reduced adhesion. Conversely, reduced expression of E-selectin and an increased induction of transforming growth factor beta (TGF beta 1) with a maximum at 0.5 Gy could be observed in endothelial cells. Macrophages immigrating the site of inflammation are known to express inducible nitrix-oxide synthase (iNOS), which in turn mediates cytotoxic and immunmodulatory effects by producing nitric oxide (NO). LD-RT of stimulated macrophages within the dose range between 0.6 and 1.25 Gy reduced NO production and iNOS-protein expression without affecting iNOS-mRNA expression. CONCLUSION Our experimental data have confirmed the antiinflammatory efficiency of LD-RT in vitro and in vivo, indicating effects on different cellular components and mechanisms of inflammation. The regulation of the adhesion between PBMC and endothelial cells and the effects on activated macrophages may mediate the antiinflammatory properties of LD-RT. Ongoing experiments will help to clarify the molecular mechanism.

Abstract
PURPOSE Substantial clinical evidence shows the efficacy of low dose radiotherapy (RT) in the treatment of painful osteoarthritis. Experimental investigations into these empirically clinical observations remain scarce. This study investigated in vivo the effects of daily 5 x 1.0 Gy versus 5 x 0.5 Gy on adjuvant induced arthritis in rats in order to explore whether there is a dose dependence of anti-inflammatory efficacy. MATERIALS AND METHODS Adjuvant arthritis in female Lewis rats was induced by intradermal injection of heat inactivated Mycobacterium tuberculosis on day 0. Both hind paws were X-irradiated daily from days 15 to 19 after induction according to four protocols (15 animals/group): group 1, 5 x 1.0 Gy (non-arthritic animals); group 2, sham-irradiated control; group 3, 5 x 1.0 Gy; group 4, 5 x 0.5 Gy. The clinical parameters arthritis score (AS), hind paw volume (HPV), body weight, and erythrocyte sedimentation rate (ESR) were determined. On days 21 and 30 histological sections of at least 12 ankle joints per group were analysed semi-quantitatively. RESULTS Local irradiation of non-arthritic rats (group 1) with 5 x 1 Gy did not induce any arthritic signs. Sham-irradiated arthritic rats (group 2) showed a full-blown arthritic syndrome. Treatment of arthritic rats with 5 x 1 Gy (group 3) or 5 x 0.5 Gy (group 4) led to a reduction of mean AS from day 21 to 29 compared with group 2 (days 27-29--group 3: p=0.037; group 4: p=0.034), with no differences in efficacy between groups 3 and 4. Concurrently, following radiation treatment there was no further increase in HPV. At the end of the observation period, this effect demonstrated a dose-dependent level of significance (days 27-29--group 3: p=0.0036; group 4: p=0.039). A significant decrease in the ESR was noted in both irradiated arthritic groups on day 21 (group 3: p=0.015; group 4: p=0.006). The histopathological analysis revealed a highly significant reduction of cartilage and bone destruction on day 30 in both irradiated groups. CONCLUSIONS This study confirms by objective criteria the anti-inflammatory efficacy of low dose RT and gives some indication for a dose dependence of its efficacy.

Abstract
Radiation synovectomy is efficacious in controlling the symptoms of rheumatoid arthritis. However, the procedure is not widely used because of concerns about leakage of radiopharmaceuticals from the treated joints. Leakage can be minimized by selecting particles of an appropriate size. In this study, we labelled microspheres with 188Re and analysed its biodistribution after intra-articular injection in rabbits with antigen-induced arthritis. Gamma camera imaging was performed to quantify the mean retention of 188Re in the knees. The mean retention of 188Re was 98.7, 94.6 and 93.6% at 1, 24 and 48 h, respectively. The biodistribution data revealed very low radioactivity in all organs at different times, which suggests the leakage of radiotracer from the knee was negligible. Our preliminary results indicate that 188Re microspheres are a potentially effective radiopharmaceutical for radiation synovectomy.

Abstract
The application of boron neutron capture therapy to rheumatoid arthritis requires the selective delivery of the boron-10 isotope to the synovitic tissue. The use of liposomes as a boron delivery method has been explored through the measurement of the time course biodistribution of boron in rats with collagen-induced arthritis (CIA). Small unilamellar vesicles were composed of a 1:1 mixture of distearoylphosphatidylcholine and cholesterol, incorporated K[nido-7-CH3(CH2)15-7,8-C2B9H11] as an addend in the lipid bilayer and encapsulated Na3[a2-B20H17NH2CH2CH2NH2] in the aqueous core. The tissue concentration of boron delivered by liposomes was determined by inductively coupled plasma-atomic emission spectroscopy after intravenous injection of liposome suspensions into Louvain rats with CIA. With the low injected doses of boron used [13-18 mg of boron per kg (body weight)], the peak boron concentration observed in arthritic synovium was 29 microg of boron per g of tissue. The highest synovium/blood boron ratio observed was 3.0, when the synovial boron concentration was 22 microg of boron per g of tissue. In an attempt to increase the synovium/blood boron ratio by lowering the blood boron concentration, a liposomal formulation characterized by a shorter blood clearance time was examined. Thus, the biodistribution of liposomes with additional K[nido-7-CH3(CH2)15-7, 8-C2B9H11] incorporated in the vesicle membrane not only demonstrated more rapid blood clearance and slightly higher synovium/blood boron ratios but also exhibited reduced boron uptake in synovial tissue. These studies with boron neutron capture therapy for CIA suggest that this form of therapy may be feasible in the treatment of rheumatoid arthritis.

Abstract
Thymus area was exposed to laser radiation in 180 Wistar male rats. Intact animals experienced a stress response to a single laser procedure (a rise in the levels of hydrocortisone, a fall in those of insulin, triiodothyronine and thyroxine). Longer exposure to laser radiation caused a break of the hydrocortisone mechanism. Similar effects were seen in the course exposure. The immune system was unchanged. In adjuvant arthritis laser radiation induced similar hormonal shifts and additional suppression of immunity. In 82 children with active juvenile rheumatoid arthritis laser therapy produced an insignificant effect, while in adults with moderate rheumatoid arthritis the response was good.

Abstract
OBJECTIVE This controlled experimental study was designed to compare the effects of a well-known NSAID, tenoxicam, with mid-laser irradiation on the inflammatory component of adjuvant-induced arthritis (AIA). Four groups of animals, each consisting of 10 Wistar rats, were included in the study. The primary concern was not to investigate the antiinflammatory effects of tenoxicam, but to compare the previously proven effects of this drug with a physical therapy agent which might be considered to have fewer side effects and/or contraindications. METHOD The first group received only 0.1 ml of complete Freund's adjuvant (CFA) and served as the control for the other groups. The 2nd, 3rd and 4th groups, after having CFA injected into the plantar surfaces of their right paws, were treated with tenoxicam alone, mid-laser alone, or with a combination of the two, respectively. RESULTS AND CONCLUSION All 3 groups showed significantly reduced paw edema compared with the control group. Although the reduction in paw edema in the animals treated with tenoxicam or with tenoxicam+ mid-laser was more significant, mid-laser is proposed as an alternative therapy for symptomatic relief in certain conditions well known to limit the use of NSAIDs.

Abstract
Radiation synovectomy has been shown to be an effective treatment for the rheumatoid arthritic knee. In this study, we evaluated the suitability of rhenium-188 as a radiation synovectomy agent. In addition, we were successful in labelling sulphur colloid with 188Re. In vitro stability tests revealed that more than 95% of the 188Re remained in colloid form over a 3-day period. Intra-articular injection of 188Re sulphur colloid into arthritic rabbit joints was followed by gamma camera imaging to quantify the leakage. The mean retention percentages of 188Re colloid in arthritic knees were 93.7% (+/- 1.4%), 90.8% (+/- 1.7%) and 87.2% (+/- 0.6%) at 1 h, 1 day and 2 days, respectively. A biodistribution study of the arthritic rabbits revealed that the highest activity outside the knees was in the liver and the kidneys. Our preliminary results indicate that 188Re sulphur colloid may be an effective radiopharmaceutical for radiation synovectomy.

Abstract
Although numerous experimental immunomodulatory regimens have been reported to be effective in the treatment of rheumatoid arthritis, they also produce undesirable side effects. An alternative specific modality of localized treatment is photodynamic therapy (PDT). In this study we treated 13-week-old MRL-lpr mice whose spontaneous arthritis was enhanced by intradermal injection of Freund's complete adjuvant (FCA). One group received transcutaneous photodynamic therapy at days 0, 10, and 20, following the FCA injection. The other groups were injected with 1 mg/kg per day indomethacin, 40 mg/kg per day cyclosporin A (CsA), or treated with 3 Gy sublethal whole body irradiation (WBI). The development of swelling was monitored for 1 month, at which time proteinuria, lymphadenopathy and the histopathology of the joints and kidneys were assessed. The results demonstrated that PDT and the conventional treatments significantly ameliorated swelling of the hindlimbs from 70% in the untreated FCA-injected animals to below the 19% level characteristic of the unmanipulated control. Histological examination showed a reduction in pannus formation, and cartilage and bone destruction, the characteristics of adjuvant-enhanced arthritis. PDT did not affect the survival rate, lymphoproliferation, or proteinuria of the treated animals. However, indomethacin increased proteinuria, and was less effective in preventing cartilage and bone destruction. Furthermore, lower doses of CsA and WBI exacerbated arthritis activity. These results indicate that photodynamic therapy can inhibit the development of adjuvant-enhanced arthritis in MRL-lpr mice with similar effectiveness to the conventional treatments, but without their negative side effects.

Abstract
Hydroxyapatite (HA), a natural constituent of bone, was studied as a particulate carrier for beta-emitting radionuclides in radiation synovectomy. Particles were radiolabeled with 153Sm or 186Re and their in vivo safety was investigated following intra-articular injection into knees of normal rabbits and rabbits with antigen-induced arthritis (AIA). Radiolabeling efficiency was greater than 95%; in vitro studies showed minimal (< or = 1%) loss of activity from particles over a 6-day period with 153Sm-labeled HA and about 5% loss of activity over a 5-day period with 186Re-labeled HA. The total cumulative extra-articular leakage of 153Sm over 6 days was 0.28% in normal rabbits and 0.09% in AIA rabbits. Leakage of 186Re from the joint was 3.05% over a 4-day period with 80% of extra-articular activity found in the urine. Histopathological evaluation of treated knees showed that HA particles are distributed throughout the synovium, embedded in the synovial fat pad. The ease and efficiency with which this HA carrier is labeled, coupled with observed extremely low leakage rates from the joint, make radiolabeled HA particles an attractive candidate as a radiation synovectomy agent for evaluation in rheumatoid arthritis patients.

Abstract
Rabbits with a bilateral antigen-induced arthritis were injected intra-articularly (i.a.) in one joint with methylprednisolone (1 mg), 90Y (18.5 MBq) or chlorambucil (1 mg) as a single dose. The severity of arthritis was determined by measuring joint swelling and skin surface temperature, macroscopic and histological changes in the joint being assessed 8 weeks after induction of arthritis when the rabbits were killed. Methylprednisolone injected at the time of antigen challenge or 3 weeks later caused a reduction in joint swelling and temperature (P < 0.05) for 1 to 6 weeks after injection. 90Y had an initial proinflammatory effect lasting several days, but later caused a modest reduction in joint swelling for up to 4 weeks (P < 0.05). Eight weeks after induction of arthritis, neither methylprednisolone nor 90Y-treated joints showed any significant reduction in erosion or histopathology compared with control arthritic joints. Chlorambucil injected 1 week after antigen challenge caused a rapid reduction in joint swelling which was maintained for the duration of the study. Joint surface temperature was reduced to a lesser extent. Eight weeks after induction of arthritis, chlorambucil-treated joints showed a decrease (P < 0.05) in all of the parameters of disease pathology assessed. Treatment with chlorambucil intra-articularly was clearly more effective than with methylprednisolone or 90Y at the doses employed and deserves further study as a potential treatment for chronic synovitis.

Abstract
We examined the effects of irradiation followed by bone marrow transplantation (BMT) on type II collagen induced arthritis (CIA) in mice. Either before or after the onset of arthritis, the mice were irradiated at levels lethal to cells, then given bone marrow cells from normal syngeneic or allogeneic mice. The BMT, especially allogeneic BMT, blocked the induction of CIA when administered before the onset of arthritis. When administered after CIA had begun, progression of the arthritis was significantly suppressed by allogeneic BMT.

Abstract
Following the demonstration that adjuvant arthritis in rats can be cured with total body irradiation (TBI) and allogeneic or syngeneic bone marrow, the efficacy of autologous bone marrow was investigated in the experiments reported here. Bone marrow from arthritic rats, harvested at the same time that the recipients were irradiated, and real autologous bone marrow were found to be similarly effective as bone marrow grafts from naive syngeneic donors. Sublethal TBI with lower doses was less effective, but the highest tolerated doses of 8 Gy approached the effect of 9 Gy and bone marrow rescue. In contrast, partial body irradiation of either the affected limbs, or of the whole body except the limbs, resulted in only partial and temporary regression of the arthritis.

Abstract
Total body irradiation followed by bone marrow transplantation was found to be an effective treatment for adjuvant arthritis induced in rats. This treatment is most effective when applied shortly after the clinical manifestation of arthritis--i.e., 4-7 weeks after administration of Mycobacterium tuberculosis. Transplantation of bone marrow at a later stage results in a limited recovery, in that the inflammatory reaction regresses but the newly formed excessive bone is not eliminated. Local irradiation of the affected joints had no effect on the disease. It could also be excluded that the recovery of arthritis following marrow transplantation is due to lack of available antigen. Transplantation of syngeneic bone marrow is as effective as that of allogeneic bone marrow from a rat strain that is not susceptible to induction of adjuvant arthritis. The beneficial effect of this treatment cannot be ascribed to the immunosuppressive effect of total body irradiation, since treatment with the highly immunosuppressive drug Cyclosporin A resulted in a regression of the joint swelling but relapse occurred shortly after discontinuation of the treatment.

Abstract
Dysprosium-165-ferric hydroxide macroaggregates (165Dy-FHMA) was used as an agent of radiation synovectomy in an antigen-induced arthritis model in New Zealand white rabbits. Animals were killed up to 6 months after treatment. 165Dy-FHMA was found to have a potent but temporary antiinflammatory effect on synovium for up to 3 months after treatment. Treated knees also showed significant preservation of articular cartilage architecture and proteoglycan content compared with untreated controls, but only during the first 3 months after treatment. In animals killed 3 and 6 months after treatment there were only minimal differences between the treated and untreated knees, indicating that the antiinflammatory effects on synovial tissue and articular cartilage preservation were not sustained.

Abstract
Six groups of 3 rabbits each were immunised with ovalbumin and received one intra-articular injection of antigen. The animals of 3 groups received local x-ray irradiation of 600 rads for 8 minutes to the right knee joint 12 days after the intra-articular challenge. Animals of the other 3 groups were not irradiated. The antigen-induced arthritis was investigated by determining the exudation is synovial fluid and by histological study of the synovium examined 48 hours, 7 days, and 4 weeks after the irradiation date. All animals in the nonirradiated groups showed a distinct chronic synovitis. Irradiated animals showed almost no synovitis 48 hours and 7 days following irradiation. In 2 rabbits synovitis had reappeared 4 weeks after irradiation with findings similar to those in the control groups. Only one animal still showed an inhibition of synovitis. X-ray irradiation of non-challenged knees did not induce any pathological changes. This time-limited effect of one local irradiation on antigen-induced arthritis seems to be mainly an anti-inflammatory action. Local immunological inhibition might possibly operate too. X-ray induced inhibition of synovitis is compared with the effect of locally injected radiocolloids.

Abstract
The short half-life beta emitter 165Dy coprecipitated as a macroaggregate with ferric hydroxide (FHMA) has been shown to destroy knee synovium in the antigen-induced arthritic rabbit. Using 153Gd as a gamma tracer for leakage studies revealed that the leakage of this system from rabbit knee joints never exceeded 1.2% over 24 hours. This is such less than the leakage rates reported from any human studies or our rabbit studies using 198Au.
