Background and Eyes are among the most sensitive organs to chemical agents especially Sulfur mustard or Hun Distilled. Therapeutic effects of anti-inflammatory drugs have been shown on the decrease of epithelium of corneal injuries after being exposed to sulfur mustard. The aim of the present study was to evaluate the protective effects of topically applied Bethametazone - Diclofenac Na in rabbits. In this experimental research, thirty six rabbits were used. Animals were randomly divided into six equal groups (6 rabbits in each group) including control, solution and mustard groups and prophylaxis groups included Betamethasone, Diclofenac Na; Betamethasone-Diclofenac Na were applied before being exposed to the sulfur mustard solution. Animals were kept for 2 weeks and the drugs were used 3 times a day for 2 weeks. Slit-lamp examinations were performed under anesthesia before exposure and subsequently at days 1, 2, 5, 7, and 14 after sulfur mustard exposure by ophthalmologists. At the end of the 14th day, specimens of cornea were obtained for ultrastructural evaluation of corneal epithelium. Statistical analysis was performed by one way analysis of variance (ANOVA) with Tukey’s test using SPSS 13 software. No significant differences were found between the control and solvent groups as far as the variables were concerned. Corneal epithelial defect and severe changes in ultrastructure of corneal epithelial surface was found in the sulfur mustard group. Clinically, corneal epithelial defect in prophylactic Diclofenac Na group (4.2±1.32) decreased significantly when compared to the mustard group (68.7±8.42) (P=0.034). Betamethasone-Diclofenac Na group (4.2±1.17) also decreased significantly when compared to the mustard group (68.7±8.42) (P=0.031). The corneal epithelial defect was not seen in prophylactic Betamethasone group. Ultrastructural damage of corneal epithelial surface and their microvillus in Betamethasone group was similar to the control group. Betamethazone is capable of protecting corneal epithelial defect in the eyes of rabbits exposed to sulfur mustard.

Background and Variation and increase in the levels of inflammatory factors and glycemia are among the major problems of type 2 diabetics. Therefore, the present study was designed to investigate the effect of beta carotene-enriched carrot juice on CRP inflammatory indexes, IL-6 and FBS glucose in diabetics. Methods and Materials: This randomized double blind clinical trial was conducted on 44 type 2 diabetics. Participants based on gender and BMI were assigned into two groups (Group A receiving 200 ml carrot juice enriched with 10 mg beta carotene and Group B receiving normal carrot juice) by randomized stratified sampling. Both groups received 200 ml carrot juice for 8 weeks for lunch (instead of cereals). A 24-hour recall was obtained for 3 consecutive and 6 concomitant days at the beginning and end of the study duration. Also, CRP, IL-6, FBS glucose and serum beta carotene levels were measured in FBS blood sample at the beginning and end of the study duration. The consumption data were fed into Nutritionist IV, and analyzed in SPSS 11.5. Each group consisted of 22 (11 male and 11 female diabetics) participants. There was a significant increase in the levels of beta carotene in group A (111.9±64.9 at the beginning and 72±43.9 at the end) (p=0.02). However, the reduction of CRP in Group A (-996.9±2172.6 at the beginning and -537.3±1412.4 at the end) was not significant (p=0.098). Also, IL-6 reduction in Group A (-0.8±2.1 at the beginning and -0.6±2.4 at the end) was not significant (p=0.085). FBS glucose was also not examined in the present study. Daily consumption of carrot juice enriched with 10 mg beta carotene for eight weeks caused an improvement in the levels of serum antioxidants including beta carotene in type 2 diabetics, with no significant effects on serum glucose and inflammatory indexes.
