Abstract
The effects of Pediiococcus acidilactici and Lactococcus lactis was evaluated on survival rate and some immunological parameters of L. vannamei during three months of cultivations. Treatments included control group, Pediococcus and Lactococcus treatments and probotic treatmentsfed at 1×109 cfu g-1. The results indicated that probiotics increased the survival rate (P<0.05). The best immune performance was shown in the probiotics treatments; phenoloxidase activity, proteins, and globulin hemolymph showed significant difference compared to the control treatment (P<0.05), whereas there were no significant influence on lysozyme activity (P≥0.05). In general, pediococcus treatment showed the best performance in enhancing the immune responses and survival rate.

Abstract
In the present investigation, infection of Lernaeacruciata parasite is reported in Farsi toothcarp (Aphaniusfarsicus) collected from Maharlu Lake basin in 2014. The prevalence of infection appeared 88.9% (45 specimens). Lernaeacruciataparasites were isolated from origin of fins, gill opercels and body surface. Frequency of parasite on each fish appeared 1 or 2 which mostly attached to branch and under operculum (45%) and base of pectoral and anal fins (43%). The L. cruciata may have been translocated into the Maharloulake Basin by an exotic Poecilid; Gambusiaholbrooki. Sever infection of this endangered endemic fish species warns that urgent reactions should be taken for conservation of Farsi tooth carps in area.

Abstract
Aims: The prevalence of Diabetes type 2 has been increased significantly during recent years. So, prevention is necessary from adolescence. This study aimed to investigate the effect of Health Belief Model-based education on preventive behaviors of Diabetes type 2 in male adolescences.
Materials & Methods: This semi-experimental study was conducted on 208 secondary school students of Hamadan city (104 students in an experimental group and 104 students in a control group) in 2018, who were selected using the stratified-proportional sampling method. Data were collected using a researcher-developed questionnaire including demographic, awareness, model constructions, and preventive behavior. Afterward, an educational intervention was implemented in the experimental group based on Health Belief Model in four 45-60 minute sessions. After one month, the data were recollected from the two groups and analyzed using Chi-square, t-test, and linear regression by SPSS 16 software.
Findings: Comparing the scores of awareness, Health Belief Model constructs, and student’s preventive practices revealed no statistically significant differences between the two groups at the beginning of the study (p>0.05). However, after the intervention, significant differences were observed between the two groups regarding awareness, the Health Belief Model constructs, and student’s preventive practices (p<0.05). Linear regression analysis indicated that self-efficacy was the most important independent predictor of type-2 diabetes-preventative behavior (p<0.05).
Conclusion: Health Belief Model-based education is effective in promoting type-2 diabetes prevention behaviors in students.
