Background and Purpose: Prophylactic dressings play a significant role in the prevention of pressure injury. However, no herbal products have been used in this regard, so far. Therefore, the present study was designed with the aim of comparing the effect of Aloe vera gel, Calendula officinalis ointment and simple sacral prophylactic dressings on pressure injury development in patients admitted to intensive care unit. Materials and Methods: The sample of this clinical trial study consisted of 90 critically ill patients. Randomization was performed by head nurse in intensive care unit. Patients in group "A" received Aloe vera gel prophylactic dressing twice a day; patients in group "B" received Calendula officinalis ointment prophylactic dressing twice a day; and patients in group "C" received simple prophylactic dressing twice a day. The development of pressure injury was compared between these three groups after the intervention. Results: Demographic variables were similar in all three groups (p> 0.05). The results showed that 3 patients (10%) who received the simple dressing, 2 patients (6.6%) who received the Calendula officinalis ointment dressing were wounded, while the development of pressure injury in patients who received the Aloe vera gel dressing was zero. The results of chi-square test showed that the frequency distribution of the pressure injury development in the two groups receiving Aloe vera gel and simple dressing was different. This difference was statistically significant (p < 0.05). However, there was no significant difference between the Aloe vera gel and Calendula officinalis ointment groups as well as the Calendula officinalis ointment group and the simple dressing. Conclusion: The results of the present study demonstrated that using Aloe vera gel and Calendula officinalis ointment prophylactic dressing twice a day can be effective in prevention of pressure injury in patients admitted to intensive care unit.

The pomegranate trees Laffan and France cultivars were sprayed with chelated Boron and Potassium with ( 0,2.5,5 g/L K2O and 200,400 mg/L B) concentration. The spraying with Boron in 400 mg/L and Potassium with 5 g/L were significantly increased the fruits set percentage, yield, physical and chemical characteristics of two cultivars under study (The fruit set was 68.94% and 75.58 % respectively) while reduced in control to 54.95 % .The average of tree yield was (45.74 kg and 72.81 kg) and in the control was 18.59 kg. The fruit fresh weight was duplicate in this treatments, fruits content of total soluble solids was (16.82% ), total sugars was 8.68% total acidity reduced to 0.88% when in the control was (9.55%,4.9% and 1.2% ) respectively.
