Background: Albumin is one of the most important proteins in the body by several important functions, it is essential in the maintenance of normal plasma colloid oncotic pressure and is the primary serum binding protein responsible for the transport of various substances in the circulation including fatty acids, hormones, and drugs. Decrease in the amount of serum Albumin (Hypoalbuminemia) is a common finding in the burn patients, but its relationship with mortality is not accurately clear. Our purpose of this study was to measure the amount of Albumin serum in burn patients and find out its relationship between the burned area and length of hospital stay.
Methods: This cross-sectional study was conducted on patients aged over 16 years who referred to the Motahari Hospital of September 2014 to February 2015 in the first 24 hours of their referral. The amount of Albumin was measured in two groups of discharged patients and patients who died while hospitalized, one week after hospital stay and in the time of discharge and death; and its relationship in terms of each other was determined by statistical analysis. We also assessed the relationship between burn and duration of hospital stay with the amount of Albumin on the day of patient’s admission.

Conclusion: Measuring the level of Albumin is one of the yardsticks that can be used for prognosis of recovery or death of burn patients, and its assessment at regular intervals in burn patients is essential.

Background: Ritalin has properties similar to amphetamines and is therefore used arbitrarily. The purpose of this study was to investigate the effect of ritalin on liver histology and some liver enzymes in streptozotocin-safe and diabetic rats.
Methods: This experimental study was conducted in September 2012 at Islamic Azad University, Damghan Branch, Iran. In this research, 80 male rats were divided into 8 groups of 10 rats, which included: control group consisting of healthy rats and experimental groups 1, 2 and 3 (healthy+ritalin), which ritalin was taken as daily gavage 2.5 mg/kg, as well as control group (diabetic) and experimental group 4, 5 and 6 (diabetic+ritalin) after 2 months of diabetic ritalin at doses of 2.5 and 5 mg/kg as daily gavages up to 30 days. At the end of the prescribed day, the rats were anesthetized and after sampling from the heart, samples were taken from the liver and samples were delivered to the laboratory.
Results: Significant decrease in albumin levels of experimental groups compared to control group (P<0.05) and significant increase in aspartate transaminase and alanine aminotransferase enzymes in all experimental groups compared to control group was observed. The rat liver tissue study showed that rats that had been exposed to different doses of riatalin for 30 days, had fibrosis around the arteries (2+), moderate to weak fibrosis, and infiltration of inflammatory cells around the arteries. In experimental groups (diabetic+ritalin), hepatocyte columns have no regularity compared to control.
Conclusion: Oral consumption of ritalin caused a disturbance in the balance of liver enzymes and elevated serum albumin levels in healthy and diabetic rats. In the experimental groups (healthy ritalin) and (diabetic+ritalin), the higher the dose of the drug, the increased levels of liver enzymes as compared to the diabetic group. Severe degrees of tissue alteration are observed in the group (diabetic+ritalin). The texture of the tissue in the group (diabetic+ritalin) disappeared and appeared in the texture of the disintegration.
