Bioaccumulation Capacity of Heavy metals in aquatic bodies can do a serious threat to food security and public health. Therefore, in this study, the amount of lead, cadmium and copper in edible tissues of hydrothermal fish in Alborz province was determined in 2017.

Twenty-one carp fish of three species were randomly selected from the Mahmoudi fishery, which supplies the Alborz hydrothermal fish market, and after acidic digestion of the specimens, the concentration of lead, cadmium and copper was determined by Atomic absorption device.

The mean concentration of lead, cadmium and copper in wild carp, amur and phytophagus in ppb and for cadmium was measured. Highest amount of lead in  Hypophthalmichthys molitrix, Cadmium in Ctenopharyngodon idella &Copper in Hypophthalmichthys molitrix was observed.Statistical comparison of the mean concentrations of the Heavy metals with the guidelines of the United Nations Food and Agriculture Organization showed that the mean concentration of all Heavy metals was lower than the permissible limit.  

Although currently the mean concentrations of the evaluated Heavy metals in the carp edible tissue of Alborz province are not exceeded, but lack of proper management of the water supply resources of fish ponds can lead to the entry of pollutants, including heavy metals, into the fish farm.In resident aquaculture tissues, endangering the health of consumers.

We report phakomatosis pigmentovascularis (PPV) detected in a 40- year-old male characterized by the presence of a port-wine stain in the background of aberrant Mongolian spots covering the back, nevus of Ota, ocular melanosis, epidermal nevus and a scaly patch with the diagnosis of discoid lupus erytematosus. These associations have not been reported yet

Narrow band Ultraviolet B (NBUVB) has been used successfully for the treatment of vitiligo. Recently, topical calcipotriol has also been used as immunotherapy or as a part of combination therapies. The aim of this study was to compare the clinical efficacy and safety of NBUVB and NBUVB plus topical calcipotriol in the treatment of generalized vitiligo. NBUVB phototherapy was given to 26 patients with generalized, symmetrical vitiligo three times weekly. Topical calcipotriol cream was only applied on the lesions located on one side of the body. Treatment was continued until cosmetically acceptable repigmentation occurred, but total cumulative dose of NBUVB did not increase from the mean of 113.4 ± 47.0 j/cm. The efficacy of treatment was evaluated by visually scoring the percentage of regimentation of the lesions at 12-session intervals by an investigator unaware of the side of calcipotriol application. The mean daily dose of NBUVB was 1.4 ± 0.6 j/cm. The median number of exposure for initial regimentation was 26.5 (range 14-38) on the side of combination therapy with calcipotriol and 25.3 (range 20-40) on the other side. After 24 sessions of treatment, 14 patients (53.9%) showed minimal to moderate improvement on the calcipotriol treated side as compared to 21 patients (80.8 %) on the other side. After 60 sessions of treatment, 16 patients (16.5 %) showed moderate to marked regimentation on the side of combination therapy with calcipotriol as compared to 19 patients (73 %) on the other side. These findings indicate that concurrent use of topical calcipotriol does not enhance the efficacy of NBUVB in the treatment of vitiligo.
