Background: Today, there is growing interest in using traditional medicine for healing cutaneous wounds. Probiotics are defined as different microorganisms that may have positive effects on prevention or treatment of special pathologic conditions. The present study was designed to investigate the effect of Lactobacillus brevis on cutaneous wound healing. Material and Methods: In this experimental study, through phenol-sulfuric acid method, 22 strains of lactobacillus isolated from dairy-traditional products were investigated in terms of exopolysaccharide production. Lactobacillus brevis, which had high exopolysaccharide (EPS) production, was selected. A wound was created on the back of male Wistar rats in control, negative control, and experimental groups. Control and experimental groups underwent regional treatment by eucerin and eucerin contained Lactobacillus brevis, respectively, but the negative-control group did not receive any treatment. On days 1, 7 and 21, the rats were killed and their cutaneous wound samples were studied. Data analysis was done through SPSS version 11.5. Results: The percentage of wound healing (99.53%) and inflammation in the experimental group on day 21 compared to control (90.55%) and negative groups (91.14%) was significantly higher (P<0.001). The number of neutrophils in the experimental group decreased in later phases of wound healing compared to the control and negative control groups. Conclusion: The present study showed that Lactobacillus brevis significantly decreases inflammation and accelerates wound healing in treated rats. The findings of this study can be applied clinically in near future

Background: The main purpose of this study was to measure the level of lipids in ICU patients and its clinical outcome, specially the mortality rate and the relationship between level of lipids and APACHE IV score.

Materials and Methods: This descriptive and cross-sectional study was conducted on 100 ICU patients. Cholesterol level was measured on the first and second days after admission of patients. This was followed by examination of clinical outcome (e.g. mortality rate) and duration of their real and predicted stay through APACHI IV. The results were analyzed by Pearson correlation using SPSS.

Results: Mean serum of HDL, LDL, and cholesterol was lower than normal. These values for the first day were 33.16, 67.97, and 131.38 and for the second day were 23.63, 54.99, and 119.88, respectively. Mean APACH E IV score was 67.72. Result of Pearson correlation coefficient showed significant relationship (p<0.05) between APACHI IV score and cholesterol level of the first and second day, LDL level of the first and second day, HDL level of the second day. Moreover, there were significant relationships were observed between the real mortality rate and the cholesterol level of the first and second days, LDL level of the first and second days, and HDL level of the first day. There was a significant significant correlation between cholesterol level and LDL of the first and second days as well as HDL of the first day and duration of admission in ICU as predicted by APACHI IV.

Conclusion: The significant relationship between lipoprotein level of serum and APACHI IV indicates considering serum lipid beside other physiologic parameters for prediction of clinical consequences including mortality rate of ICU patients
