The aim of the research is to determine the adequacy of dialysis in patients undergoing hemodialysis through the evaluation of serum Bun and Cr, before and after dialysis and investigate the biochemical effect of dialysis on kidney in Lar city. This research was descriptive-analytical and cross-sectional on 135 patients undergoing dialysis. Data collection was done through the researcher's demographic questionnaire. Blood creatinine and urea levels were measured by Jaffe and enzymatic methods, respectively. Dialysis adequacy was calculated through KT/V and URR parameters. The data was analyzed using descriptive and inferential statistical tests in SPSS software and by Pair t-test. Most hemodialysis patients of these centers had KT/V less than 1.2. Also, 36.1% of the subjects had URR>65 and 47.5% had KT/V>1.2. A significant decrease in serum urea and creatinine after dialysis was observed. The comparison of the types of membranes in the amount of urea and creatinine clearance showed a difference between these membranes in correcting the amount of urea and creatinine, So, HD type was the most efficient and the R4 type was the least efficient. The S3 membrane has a higher filtration rate than others, which can be the reason for this difference. The average difference of alkaline phosphatase activity before and after dialysis with S3 membrane was more than other membranes, although this difference was not significant. BUN and creatinine showed a significant decrease after hemodialysis compared to before hemodialysis. The result showed that 36.1% had adequate dialysis; But in others, do not have adequate dialysis efficiency.

Abstract
Fish meat has high nutritional value and putrescence. For this reason, it is very important increase the shelf life and fish meat quality. In this study tried to go up the shelf life and quality fish meat by ozon ice. The number of Rainbow trout with weight 300±10 purchased and transferred to the Mashhad laboratory (Iran) immediately. The fish was divided into four groups, control (A), dose of 3g (B) 4g (C) and 5g of ozone per 50 kg ice with the brine 5% (D). Daily to the fourteenth day of corruption were used on the WHO chart. Moreover sampling of skin, meat and gill tissue was done every day to the 12th day for check bacterial by (PCA) cultured. The amount of histamine (ELISA method), peroxide (PV) (Egan method) and TVN (Kldal distiller method), was obtained respectively. The results showed that A sample (control) had corrupted the most number of bacteria in depth and surface have existence ten days significantly (P <0.05). Amounts of peroxide and TVN in B sample lower than to the other fish samples and had no significant increased (P 0.05). Histamine changes was not significant in all samples (P<0.05) and all of the fishes ozone treated have better maintenace and quality. Thus it can be infered that ozone is an effective mater to increase the durability of fish.
