Abstract
Background: Vitamin D deficiency seems to be associated with pulmonary function deterioration. The present study was designed to investigate the relationship between serum vitamin D and forced expiratory volume in patients with chronic obstructive pulmonary disease (COPD).
Methods: From September 2011 to April 2012 eighty consecutive patients with COPD presented to an outpatient clinic of Babol University- Teaching Hospital entered to the study. Diagnosis of COPD was confirmed according to clinical findings and pulmonary function test. Serum 25-hydroxyvitamin D (25-OHD) was assessed by chemiluminuscence method and postbronchodilator forced expiratory volume in 1s (FEV1) was measured in all patients. The objective of this study was to determine the relationship between serum 25-OHD concentrations and FEV1 value. The patients were classified according to serum 25- OHD concentrations as less 10ng/ml, 10-19.9 20-29.9 30-39.9 and 40ng/ml or higher. The mean values of FEV1 for each class of serum 25-OHD were determined and compared.
Results: The mean age of patients was 67.4±11.5 years. The mean FEV1 volume in serum 25-OHD deficient COPD was lower than sufficient COPD (1.550±0.55 vs 1.650±-0.58, p=0.45). Mean FEV1 values increased from 1.55±0.55 L in patients with mean serum 25-OHD <20 ng/ml to 1.94±0.74 L in COPD patients with mean serum 25-OHD ±>40 ng/ml. There was a dose-response pattern of relationship between FEV1 and serum 25-OHD. However, the relationship did not reach to a statistically significant level.
Conclusion: These findings indicated a relationship between serum 25-OHD concentration and FEV1 volume in patients with COPD and suggest optimization of serum vitamin D levels in COPD.

Abstract
Background: Propolis as a natural product has shown beneficial effects on human health. This study was aimed to investigate the chemical compositions and biological activity of three different extracts of propolis from two distinct geographic areas in Iran.
Methods: The chemical composition of Iranian propolis extracts that were collected in the Spring of 2016 from two provinces in northern Iran: Ardabil and Polur in Mazandaran Province were measured through gas chromatography-mass spectrometry (GC-MS) methods. In addition, antimicrobial activity and cytotoxicity effect on HN5 and LNCaP cell lines were evaluated. The data were analyzed using one-way ANOVA and p<0.05 was considered as significant.
Results: The GC-MS analysis identified the presence of compounds that belonged to the different groups such as aromatics acids and their related esters, flavonoid and flavonoid derivatives and terpenes. Flavanone was the most dominant compound of flavonoids. The maximum growth inhibition was observed against S. aureus of ethanolic extract of propolis (p<0.05). Moreover, cytotoxicity showed that ethanolic and dichloromethane extracts had more inhibitory effects on cell lines than the water extract.
Conclusion: The results determined that extracts had the highest percentage of flavonoids. Therefore, it is expected that the synergistic effect of the main components of propolis is related to the increase of biological activity of propolis.

Abstract
Background: Nowadays, radiotherapy is used effectively for treatment of head and neck cancers. Mucositis is one of the most important side effects of radiotherapy. Radio-protective agents protect tissues and cells against the adverse effects due to ionizing radiation and cleave radiation-induced free radicals. Lycopene as a potent antioxidant protects cells against oxidative damage by free radical–scavenging. The present study investigated the antioxidant effect of lycopene on oral mucosa of irradiated rats.
Methods: In this experimental animal study, 28 rats were placed in four groups as follows: treated with 50 mg /kg of lycopene (L50), solvent+irradiation (SR), 25 mg / kg of lycopene+irradiation (LR25), and 50 mg / kg of lycopene+irradiation (LR50). The rats received lycopene intraperitoneally. On the irradiation day (day 0) and tenth day of radiation, blood samples were taken from the animals for FRAP and TBARS tests.
Results: The results showed that the LR50 group didn’t show mucositis higher than Grade 2. There was a significant difference (p <0.05) between SR and the L50 regarding the severity of mucositis. In addition, L50 showed higher antioxidant activity and lower peroxidation than SR.
Conclusion: The lycopene reduced the severity of mucositis. Therefore, it can be used as a potential and promising nutritional substance to prevent radiotherapy complications, especially in the treatment of head and neck cancers. However, further research is necessary to confirm these results.

Abstract
Background: This study aimed to assess the effect of graphene oxide (GO) nanoparticles mouthwash on oral mucosa, Streptococcus mutans (S. mutans) count in the saliva of rats, and human enamel surface microhardness, in comparison with fluoride mouthwash.
Methods: This study was conducted in two phases namely an animal study, and an in vitro experimental study. GO mouthwash (0.005%), sodium fluoride (NaF) mouthwash (0.05%), and a combination of both (0.05% NaF-0.005% GO) were prepared. The oral cavity of 36 rats was inoculated with S. mutans, and they were randomly divided into 4 groups according to the type of mouthwash. The control group received saline mouthwash. Fourteen days after using the mouthwashes, all rats were sacrificed, and the salivary S. mutans count was measured. The buccal and tongue mucosa were also histologically examined for the type and severity of inflammation, number of blood vessels, epithelial thickness, and epithelial keratinization. For microhardness testing, 40 sound extracted human premolars were randomly assigned to four groups (n=10) of culture medium with S. mutans and different mouthwashes. The enamel microhardness was measured at 7 and 14 days, and compared with the baseline value.
Results: The mean S. mutans count in the saliva of rats in GO and NaF-GO groups was significantly lower than that in other groups (p<0.001). Enamel microhardness in NaF and NaF-GO groups significantly increased at 7 and 14 days, compared with baseline.
Conclusion: Addition of GO nanoparticles improved the antibacterial properties without causing adverse mucosal effects such as ulceration, acute inflammation or atrophy of the epithelium of the oral mucosa, but had no effect on surface hardness of the enamel.

Abstract
Background: Dialysis cuffed catheter dysfunction results in inadequate dialysis, increased sepsis risk, and a shortened catheter life. It may be possible to prolong catheter function by identifying the causes of cuffed catheter dysfunction.
Methods: This study was a cross-sectional descriptive study conducted in 2021-2022 on hemodialysis patients with jugular cuff catheters. The catheterizations were performed using the Seldinger technique and were confirmed by fluoroscopy. A 12-month follow-up was conducted with respect to the performance of the cuffed catheter.
Results: A total of 123 patients underwent hemodialysis over 2 years via a cuffed catheter. Catheters were most commonly inserted into the right internal jugular vein, with lengths of 19 cm (tip to cuff). The rate of dysfunction of cuffed catheters was 27.6%. Catheter-related thrombosis was the most common cause in 10 cases (29.4%), followed by catheter tip fibrin sheath in 8 cases (23.5%) and catheter tip malposition in 8 cases (23.5%). Furthermore, 18 patients (52.94%) of cuffed catheter dysfunction occurred within 3 months of catheter placement, based on our study. The dysfunction of cuffed catheters on the left side 23 (67.64%) is more prevalent than the right side 11 (32.35%) (P=0.043); the malposition of catheter tips is more prevalent on the left side (P=0.023).
Conclusion: Most commonly, cuffed catheter dysfunction is caused by thrombosis, fibrin sheath formation, and catheter tip malposition. Cuffed catheter failure can be reduced by carefully monitoring the catheter's path and tip position, searching for fibrin sheaths when investigating cuffed catheter failure, and preventing thrombotic events.

Abstract
Background: The COVID-19 pandemic significantly threatens immunocompromised patients. We aimed to investigate the clinical and paraclinical findings and consequences of COVID-19 in kidney transplantation recipients.
Methods: In this retrospective study, kidney transplant recipients admitted to Ayatollah Rouhani, Shahid Beheshti, and Shahid Yahyanejad referral hospitals of Babol, North of Iran, with a diagnosis of COVID-19, were examined. Information such as demographic and laboratory findings, clinical symptoms, and treatments received was entered into pre-prepared questionnaires.
Results: Out of the 35 patients included in the study, 19 (54.3%) were males, and 16 (45.7%) were females. The mean age of patients was 47.46±11.28. Among the clinical symptoms, cough and decreased level of consciousness were associated with a higher mortality rate (P= 0.02). Furthermore, the mortality rate was found to be 17.1%. C-reactive protein (CRP) level, oxygen saturation percentage, and diffuse lung involvement were significantly associated with COVID-19 mortality (p <0.05). In this study, no correlation was found between the amount of Cr and the outcome of COVID-19 disease (P = 0.66), and also, no significant relationship was found between the amount of BUN and the outcome of COVID-19 (P = 0.46). Even the patient who was admitted with a Cr of 6.4 did not die and was discharged with a Cr of 3.4.
Conclusion: Due to the higher mortality rate in transplant patients with COVID-19, the need for more clinically severe treatment and intensification of care in this group of patients is essential.
