Fish immunology
If a piece of life tissue of a person is grafted to another person, after a short period the transplanted tissue will be disintegrated and disappear. Also in most infectious diseases, the victim will be resistant against the malady after recovery. Such body responses are called Immunological reactions and the study of these reactions, mechanisms involved and related consequences is known as Immunology. Of the most important applications of Immunology are disease prophylaxis (through vaccination), diagnosis and treatment
Macroscopic and microscopical investigations of the effects of alcoholic extract of henna (Lawsonia inermis) on skin healing of experimentally induced tissue damage in macro fish (Labidochromis caeruleus)
One of the well-known herbal drugs is henna (Lawsonia inermis). According to the components in henna, several beneficial properties (i.e., antimicrobial, anti-inflammation, wound healing, trypsin inhibitory and antioxidant) have been reported. The present study was designed to investigate the effects of two natural substances (sodium chloride and henna extract) on experimental skin lesion due to pulling out scales and trypsin injection (0/02 ml, beneath dorsal fin). For this purpose, 54 fish in weight 5/5±0/55 of were divided to 3 groups, with eighteen fish in each group. Fishes were placed in laboratory condition in 22-25 ˚C. Two, four and six days after induction of skin injury, fishes were treated with different agents for 10 minutes. First group was treated in salt water 1%, second group in henna extract 0.5% and the control group without any additives. The fish were sampled weekly, 3 times by sampling from the wound. Macroscopic examination showed that color changes of wound place decreased in henna group in comparison with that other groups. In third week of healing, normal appearance of skin were seen in most of fishes in henna and salt groups. Microscopic study revealed a decrease in inflammatory cells infiltration in henna group second week after induction of skin injury. It seems that henna by decreasing inflammatory process, can also prevent skin damage and secondary infections that can help faster and more effective on wound healing than salt bath in fish
Effectiveness of Eye Movement Desensitization and Reprocessing on Anxiety in Children with Thalassemia in a 12-month follow up
Background and Objective: Thalassemia is the most common genetic diseases in the world and especially in our country. For many reasons, including chronic disease, health care costs, the expected mortality Ray disease states such as anxiety, psychological and social problems in thalassemia. The aim of the present study was to assess the efficacy of Eye Movement Desensitization and Reprocessing (EMDR) on anxiety of children with thalassemia in a 12-month follow up..
Methods: It was a clinical trial study, which was performed on 60 patients with Thalassemia in 2013-2014. A total of 60 thalassemic patients based on Beck anxiety inventory, selected using sampling and were randomly divided into experimental and Control groups. in experimental group, eye movement desensitization and reprocessing therapy was perfomed in five sessions and The control group received no intervention. In order to collect information on demographic questionnaire and Beck Anxiety Inventory were used. data were gathered on anxiety symptoms at pretreatment, posttreatment and 12 month follow up and were analyzed using descriptive statistics, repeated measures and chi square.
Results: The average age of the participants was 15.22±1.93 years old. This study shows that the mean or average level of anxiety children with thalassemia in the experimental group before and after intervention and in a 12-month follow up group 34.73 ± 5.62, 19.90 ± 2.48 and 19.23 ± 2.48 respectively; repeated measures ANOVA showed significant statistical difference (p<0.001).
Mean of anxiety symptoms in before , after intervention and 12 month follow up in control group was 34.93± 5.69 , 34.53± 5.61 and 33.86±5.83 respectively, which using with repeated measures ANOVA did not show significant difference (p>.05)
Conclusion: This study shows that Method of eye movement desensitization and reprocessing as an alternative method to treat or reduce anxiety, aggressive children with thalassemia .Trained Nurses can use this new method is effective in the treatment of anxiety
