An intralenticular foreign body is a rare condition, but the prevalence is about 5% of all intraocular foreign bodies and it can result in serious complications. We managed them according to the size, location, material type and the risk of infection. This article reported a 51year-old patient with an intralenticular metal foreign body in the left eye, who underwent phacoemulsification lens extraction with removal of the intralenticular foreign body and insertion of a posterior chamber intraocular lens. The visual outcome was good.

·We report clinical manifestations,angiographic,and optical coherence tomography (OCT) findings of four cases with bilateral idiopathic cystoid rnacular edema (CME).All were male with age between 30 and 52 years.All of them had compliant of bilateral visual loss during the last week.Fundus examination of their eyes showed macular edema in the posterior pole bilaterally. Fluorescein angiography revealed no specific finding in one of them and "typical petaloid pattern" in others.OCT showed subretinal fluid in all of them.All patients were managed with diagnosis of idiopathic CME,and after 6 weeks they had improved visual acuity.

·Color blindness is a common disorder in human. Congenital color blindness is a trait of X-linked recessive inheritance. In our study, one thousand and six hundred female students were selected by randomized group sampling and tested by "Ishihara pseudoisochromatic plates".Among this(0.63%) showed color vision deficiency; among these cases six girls (0.38%) had deuteranomaly and 4 girls (0.25%) had protanomaly.

Objectives: In this study, natural substances were introduced as primary dental pulp caps for use in pulp therapy, and the antimicrobial and cytotoxic properties of these substances were investigated. Materials and Methods: In this in vitro study, the antimicrobial properties of calciumenriched mixture (CEM) cement, propolis, and propolis individually combined with the extracts of several medicinal plants were investigated against Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. Then, the cytotoxicity of each substance or mixture against pulp stem cells extracted from 30 primary healthy teeth was evaluated at 4 concentrations. Data were gathered via observation, and optical density values were obtained using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) test and recorded. SPSS software version 23 was used to analyze the data. Data were evaluated using 2-way analysis of variance and the Tukey test. Results: Regarding antimicrobial properties, thyme alone and thyme + propolis had the lowest minimum inhibitory concentrations (MICs) against the growth of S. aureus, E. coli, and P. aeruginosa bacteria. For E. faecalis, thyme + propolis had the lowest MIC, followed by thyme alone. At 24 and 72 hours, thyme + propolis, CEM cement, and propolis had the greatest bioviability in the primary dental pulp stem cells, and lavender + propolis had the lowest bioviability. Conclusions Of the studied materials, thyme + propolis showed the best results in the measures of practical performance as a dental pulp cap.

OBJECTIVETo evaluate the insecticidal effect of diatomaceous earth (DE) against adults and nymphs of Blattella germanica.

METHODSThis cross sectional study has been done on the laboratory strain of German cockroaches. Two stages, nymph and adult, were exposed to six dose rates of the DE, 2.5, 5, 10, 15, 20 and 25 g/m(2), at 24, 48 and 72 h exposure period. Mortality (number of dead cockroaches) was assessed after 24 h. Other exposed specimens were transferred to the beakers contained food and water for counting the retard mortality rate after 1 week.

RESULTSIncreasing in dose rates of DE increased mortality rate, so that the lowest and highest mortality rates were observed in 2.5 and 25 g/m(2), respectively. The results of the statistical analysis showed no significant difference in the lethality of 50% of DE plus water on the German cockroach nymphs.

CONCLUSIONSDue to the resistance of German cockroach against organochloride, organophosphorus, carbamate and pyrethriodes insecticides, it is suggested to use DE for insect's control.
