Abstract
Within the framework of the article, the authors analyzed the available information about the damage to the lacrimal apparatus during radionuclide therapy. In focus of article lesions of the lacrimal production system, the main and accessory lacrimal glands, as well as lacrimal drainage are considered. It was found that damage to the lacrimal apparatus is characteristic of 131I therapy for thyroid cancer, as well as for radioligand therapy using anti-PSMA antibodies labeled with 177Lu and 225Ac. 177Lu-PSMA and 225Ac-PSMA may damage the lacrimal gland with the formation of a clinically pronounced "dry eye syndrome". The pathogenesis of such lesions is associated with the accumulation of a radioisotope in the tissues of the lacrimal apparatus, while during therapy with 131I, accumulation is realized due to the expression of the sodium-iodine symporter in the nasolacrimal duct, and during therapy with 177Lu-PSMA and 225Ac-PSMA, the radiobiological effect is realized in connection with the expression PSMA by lacrimal tissue. An analysis of the available sources showed that to date there are no results of systematic studies on the problem, there is a lack of knowledge regarding the individual risks of developing these complications, methods for their prevention that have proven effectiveness have not been developed, and the treatment methods used, having relatively low efficiency, are not specialized. The authors concluded that the strengthening of interdisciplinary interaction, as well as the organization verification methodology and correct studies, can contribute to solving problems related to the study of the complications under consideration.

Abstract
PURPOSE To evaluate the radioprotective effect of spirulina (SP) on the lacrimal glands after RAI treatment. METHODS A total of 30 rats were separated into control, RAI and SP group. The radioprotective effect of SP on lacrimal glands was evaluated with histopathological and cytopathological analysis. Lacrimal glands were analyzed for tumor necrosis factor alpha (TNF-α), interleukin-2 (IL-2), IL-4, IL-6, IL-10, nuclear factor-kappa B (NF-κB), total oxidant status (TOS) and total antioxidant capacity (TAC) levels. RESULTS RAI increased TNF-α (p = .001), IL-6 (p = .018), and NF-κB levels (p < .0005). Following the administration of SP, TNF-α (p < .0005), IL-4 (p = .026), and IL-6 (p = .006) levels decreased. RAI decreased the TAC levels (p = .001), and co-administration of SP increased the TAC level, but was not statistically significant. SP decreased the TOS level after RAI (p = .022) . CONCLUSIONS SP protects lacrimal glands from RAI-induced damage.

Abstract
Background: Radioiodine ablation is a frequent procedure for the management of thyroid cancer. In several cases, this treatment is followed by secondary acquired nasolacrimal duct obstruction (SALDO). Risk factors for the development of SALDO are not defined yet.Aim - to provide clinical and demographic characteristics of tearing in patients after radioiodine treatment.Materials and methods: Material was obtained by a phone survey of 588 patients who underwent radioiodine treatment. Age and gender of the respondent, strength of administered medication, and time since the end of treatment were taken into account. Patients were asked if they had dry mouth and/or tearing at the time of the survey. Differences in values were found using parametric and nonparametric criteria, Pearson's χ2 test. Differences were considered statistically significant at p ≤ 0.05.Results: Severe tearing was reported by 8.8% of patients after single-dose radioiodine treatment and 23.9% of patients after repeated one. The age of patients with severe tearing and without it showed statistically significant difference in patients after single-dose radioiodine treatment and no statistically significant difference in patients after repeated radioiodine treatment. Administration of 4 GBq or more in patients aged 61-71 years results in 4-fold increase of the risk of severe tearing. Dry mouth causes 3.6-fold increase of the risk of developing severe tearing.Conclusion: Finding risk factors for SALDO development after radioiodine therapy in the future will contribute to an individualized approach to the prevention of this complication. Development of preventive measures is one of the tasks facing researchers.

Abstract
PURPOSE We have evaluated the potential radioprotective, antioxidant and anti-apoptotic effects of resveratrol (RSV) against high-dose radioactive iodine (RAI) therapy associated damage of the lacrimal glands by biochemical, histopathological and immunohistochemical methods. MATERIALS AND METHODS Thirty Wistar-albino rats were randomly divided into three groups; the control group received no treatment or medication, the RAI group received RAI but no medication and the RSV group received oral RAI and intraperitoneal RSV. RSV was started at day one, before RAI administration, and continued for 8 days. Bilateral intraorbital (IG), extraorbital (EG), and Harderian (HG) lacrimal glands were evaluated in all rats for histopathological, immunohistochemical, tissue cytokine and oxidant and antioxidant level assessment. RESULTS RSV group restored inflammation, fibrosis, vacuolization, change in nucleus characteristics, lipofuscin-like accumulation and cellular morphologic patterns were statistically significant in all lacrimal gland types, compared to the RAI group (p < .05 for all variables). Similarly, elevated Caspase-3 and TUNEL levels in the RAI group were significantly alleviated in the RSV group in all lacrimal gland types (p < .05 for all variables). RAI administration significantly elevated TNF-α, IL-6, NF-кb levels, and decreased IL-10 levels (p < .05 for all parameters) whereas TOS levels significantly increased and TAS levels were significantly decreased. However, RSV significantly diminished TNF-α, IL-6, IL-4, and NF-кb levels. Furthermore, RSV significantly decreased TOS and increased TAS levels (p < .05 for all variables). CONCLUSIONS We conclude that with its anti-cancer effect as well as its antioxidant effect RSV has protected the histopathological pattern of the lacrimal glands from the damage, decreased inflammation in histopathologic assessments, and decreased tissue cytokine levels, apoptosis and DNA fragmentation on the lacrimal glands after RAI.

Abstract
PURPOSE To evaluate antioxidant effects of active vitamin D (calcitriol) against high-dose radioiodine (RAI) therapy-associated damage of lacrimal gland. MATERIALS AND METHODS Wistar albino rats were used and divided into three groups randomly (n = 12/group). The first group was appointed as the negative control group and received no RAI or medication. The second group was appointed as the positive control group that only received 3 mCi/kg (111 MBq/kg) RAI via gastric gavage and the last group was the treatment group that received 3 mCi/kg RAI via same method and calcitriol (200 ng/kg/day) via intraperitoneal administration. Seven days after RAI administration, bilateral intraorbital (IG), extraorbital (EG) and Harderian (HG) glands were removed for the evaluations of histopathologic, tissue cytokine, total oxidant status (TOS) and total antioxidant status (TAS). RESULTS RAI led to significant increase in tissue TOS, TNF-α, IL-6 levels and significant decrease in IL-10 and TAS levels (p < 0.05 for each). Addition of adjunctive calcitriol reversed all these parameters significantly (p < 0.05 for each).The following histopathologic parameters were seen more frequently in positive control group than the other groups: Abnormal lobular pattern, perivascular infiltration, periductal infiltration, lipofuscin-like accumulation, acinar atrophy, periductal and periacinar fibrosis in all lacrimal gland types (p < 0.05), acinar fibrosis in EG (p = 0.049), periductal fibrosis in EG and HG (p = 0.049 and 0.038, respectively), abnormal cell outlines in EG and HG (p = 0.020 and 0.011, respectively) and variation in cell size in the IG and the HG (p = 0.003 and 0.049 respectively). CONCLUSIONS RAI caused significant oxidative stress and inflammation in lacrimal glands. Vitamin D demonstrated potent anti-inflammatory, antioxidant and radio-protective effects on lacrimal glands in histopathologic, tissue cytokine and oxidant/antioxidant level evaluations.

Abstract
OBJECTIVE The aim of this study was to investigate the presence of ADAMTS2 and ADAMTS5 in the salivary gland (SG) of rats after high-dose radioiodine therapy. METHODS A total of 36 male Wistar albino rats were used for this study. Thirty-six male rats were divided randomly into six groups: control and five radioactive iodine (RAI) treatment groups of six rats each. All animals were killed. The evaluation of biodistribution and histopathological studies were carried out on the SGs removed. Real-time PCR and immunohistochemical analysis were carried out to determine mRNA and protein expression levels of ADAMTS genes. Differences between the groups were evaluated statistically. RESULTS In RAI-treated groups, ADAMTS2 and ADAMTS5 gene expression was observed to increase, whereas there was no mRNA or protein expression in the control group. There were statistically significant increases in the mRNA expression of ADAMTS2 (all RAI-administered groups in parathyroid gland and at 4, 24, and 48 h in submandibular gland) and ADAMTS5 (all RAI-administered groups, except on the 30th day in the parathyroid gland and all RAI groups in submandibular gland). Through immunohistochemical analysis, the staining pattern in the extracellular source was also observed in the overexpressed ADAMTS2 and ADAMTS5 groups. Nuclear coarsening and partial focal subnuclei vacuolization were determined in all RAI-administered groups with histopathological examinations. CONCLUSION An increase in the mRNA expression levels of ADAMTS2 and ADAMTS5 genes was detected in the RAI-administered groups. These results suggested that ADAMTS2 and ADAMTS5 genes might play a role in radiation exposure and radioiodine-induced SG changes.

Abstract
PURPOSE The aim of this study was to evaluate the effect of lycopene against radioactive iodine (RAI)-related gastrointestinal tract acute damage in a rat model as a novel radioprotective agent. MATERIALS AND METHODS Twenty Wistar albino rats were divided into two equal groups: group 1 was administered only RAI and group 2 was administered RAI and lycopene. All rats were killed 24 h after the last administration of the agents and the gastrointestinal tract organs were removed surgically for histopathological examination. RESULT The presence of lamina propria edema in the duodenum (P=0.003) and ileum (P=0.02), ulcer in the duodenum (P=0.033), mucosal erosion in the stomach (P=0.001), mucosal degeneration in stomach (P=0.02) and colon (P=0.02), necrosis in all tissues (P value for stomach=0.005, duodenum=0.001, ileum=0.001, colon=0.001), inflammation in those tissues (P value for; stomach=0.003, duodenum=0.02, ileum=0.011, colon=0.033), and fibrosis in those tissues (P value for; stomach=0.02, duodenum=0.003, ileum=0.003, colon=0.001) were statistically less frequently observed in the lycopene group compared with the RAI group. CONCLUSION As a first study assessing the protective effect of lycopene on gastrointestinal tract organs in a rat model after RAI, these preliminary basic research findings suggest that lycopene appears to exert radioprotective effects against RAI-induced acute gastrointestinal tract damage.

Abstract
BACKGROUND Some complications of radioiodine therapy have been reported, but the involvement of the eyes and adnexa is rarely discussed. The purpose of this study was to determine the correlation among ocular surface changes, xerostomia, and changes in the nasal mucosa associated with radioiodine therapy. METHODS Patients subjected to radioiodine therapy (group 1) or not subjected (group 2) were prospectively evaluated by examinations of the ocular surface and tear film, saliva production, and nasal endoscopy. Ocular and nasal symptoms and xerostomia were evaluated using questionnaires. RESULTS Evaluation of the ocular surface did not indicate significant differences between the groups. Nasal endoscopy revealed higher mucosal pallor in group 1 and worsening of the endoscopic appearance. Worsening of ocular symptoms and nasal symptoms, xerostomia, and a significant decrease in salivary production was also observed in group 1. CONCLUSION Subjective worsening of xerostomia, xerophthalmia, nasal symptoms, and changes in the nasal mucosa in group 1 was observed.

Abstract
PURPOSE To evaluate protective effect of coenzyme Q10 (CoQ10) in lacrimal glands against high-dose radioactive iodine (RAI)-associated oxidative damage. MATERIALS AND METHODS Thirty Wistar albino rats were randomly divided into three groups. Group 1 was the control group. Group 2 received 3 mCi/kg RAI via gastric gavage but no medication. Group 3 received 3 mCi/kg RAI via gastric gavage and 30 mg/kg/day CoQ10 intraperitoneally. CoQ10 was started at day one just before RAI administration and continued for five days. Seven days after RAI therapy, the animals were anesthetized and decapitated. Intraorbital (IG), extraorbital (EG), and Harderian (HG) lacrimal glands were removed bilaterally for histopathological and tissue cytokine level assessments. RESULTS Abnormal lobular pattern, acinar fibrosis, lipofuscin-like accumulations, perivascular infiltration, cell size variation, abnormal cell outlines, irregular nucleus shapes in all lacrimal gland types (p < 0.05 for each), periductal fibrosis, periductal and periacinar fibrosis in EG (p = 0.01, 0.044, respectively) and in HG (p = 0.036, 0.044, respectively), periductal infiltration in HG (p = 0.039) and IG (p = 0.029), acinar atrophy in EG (p = 0.044), and cell shape variation in IG (p = 0.036) were observed more frequently in group 2 than in other groups. RAI caused significant increase in TNF-α, IL-6, nuclear factor kappa B, and total oxidant status, and decrease in IL-2, IL-10, and total antioxidant status levels (p < 0.05 for each). Addition of CoQ10 decreased all cytokine levels, increased nuclear factor kappa B levels more, and increased total antioxidant status levels significantly (p < 0.05 for each). CONCLUSIONS RAI administration causes prominent inflammatory response in lacrimal glands. Addition of CoQ10 ameliorates the oxidative damage and protects lacrimal glands both in histopathological and tissue cytokine level assessments. Protection of lacrimal glands against oxidative damage may become a new era of CoQ10 use in the future.

Abstract
PURPOSE To determine the role of Molsidomine in preventing radiation-induced retinopathy after head and neck region irradiation of rats with a single radiation dose of 15 Gy. MATERIALS AND METHODS Male Wistar albino rats were randomly grouped into five as follows: (1) control group rats, which were applied through an intraperitoneal (i.p.) vehicle without radiotherapy (RT); (2) RT group rats received a single dose of 15 Gy irradiation and after daily 0.1 ml vehicle i.p. for 5 consecutive days; (3) molsidomine (MOL) group rats were treated for 5 consecutive days by i.p. with 4 mg/kg/day MOL; (4) irradiation plus MOL group (RT+MOL) rats received irradiation and after 10 days single daily i.p. dose of MOL for 5 consecutive days; and (5) MOL+RT group rats were treated for 5 consecutive days by i.p. with MOL before RT. At the end of the work the rats were sacrificed under high-dose anesthesia on the 16th day and then eye tissues were taken for histopathological, immunohistochemical (caspase-3), and biochemical analyses (superoxide dismutase [SOD], glutathione peroxidase [GSH], and malondialdehyde [MDA]). RESULTS RT significantly decreased both the content of GSH and the activity of SOD, and significantly increased the production of MDA level in the rat eyes. MOL treatment significantly increased the SOD and GSH levels and significantly decreased the MDA production (p < 0.0001). In addition, RT significantly increased the number of ganglion cells (GCs; p = 0.001), whereas especially pretreatment with MOL improved (p = 0.013). RT led to significant retinopathy formation, and MOL therapy protected the retina from radiation-induced retinopathy (p < 0.0001). CONCLUSIONS We suggest that MOL is a powerful antioxidant and free radical scavenger that prevents the rat eyes from radiation-induced retinopathy and oxidative stress.
