Introduction: In diabetes mellitus the increase of AgII (Angiotensin II), IGF-1(insulin like growth factor-1) and growth hormone induce kidney lesions especially changes in content and thickness of GBM and widening and fusion of podocyte pedicles. In this research for the first time the combination of Losartan (AT1 receptor blocker) and Octreotide (Somatostatin analogue) were used in order to prevent glomerular epithelial lesions.
Materials & Methods: In this experimental study 15 male rats (2 months age) were uninephrectomised from left flank and divided in 5 groups (3 per group). 7 days later diabetes was induced in 2th, 3th, 4th and 5th group by Alloxan (120mg/kg) subcutaneously. 5 days after diabetes induction, the third group received Losartan (5mg/kg/day) orally, 4th group Octretide (10 ŭg/day) subcutaneously and 5th group both two drugs with the mentioned doses for 8 weeks. The 2th group was served as diabetic non treatment group. Kidneys of all groups were fixed by perfusion technique. After second fixation of 1 mm3 cortex parts in Osmium Tetroxide, they were processed in TAAB812 resin for embedding. Thin sections (600 nm thickness) were prepared and investigated by transmission electron microscope qualitatively.
Results: Losartan inhibited fusion and thickening of podocyte pedicles but in some cases couldn,t maintain the 3 layer form of GBM. Octreotide had little effect on inhibition of fusion and thickening of podocyte pedicles and no effect in 3 layer form maintaining of GBM. Combined therapy inhibited fusion and thickening of podocyte pedicles and maintained 3 layer form of GBM but in some cases the lamina rara near endothelium was not seen.
Conclusion: Octreotide have little effect on prevention of glomerular epithelium lesions. However Losartan could prevent glomerular epithelium lesions well, but combined drug therapy showed better results comparing Losartan.

Background: Pain is an unpleasant feeling which humans experience. It is a warning sign of the damaged tissue. Due to the awful sense of pain, scientists always attempt to relieve it. Retinoic acid (RT), an active metabolite of natural vitamin A has important roles in modulation of the inflammatory responses. The aim of the present study was to analyze the pain threshold of rats which had microinjections of RT, applying acute and chronic models. Methods and Materials: In this study, the tail flick and formalin tests were used to determine pain threshold. In each test, the acute and chronic pain thresholds of 252 Wistar male rats (275 ± 25 gr) were assayed. The druge were injected in the acute model one-dose30 minutes before behavioral testing and in chronic model two-dose for one or two-weeks. The rats of both models divided randomly into six groups (n=7). In four treatment groups retinoic acid (RT) intra cerebro ventricular (i.C.V) were injected as dosagc of 0.5, 3 and 6 (µg/kg) micrograms per kilogram. In control group, was microinjected by ACSF. In vehicle group injected RT solvent (DMSO+ Distil water). Results: The resuits Showed acute injection of RT did not change pain thresholds in the tail-flick methd, but the chronic administration of RT (0.5, 1, 3, 6 µg/kg) reduced tail-flick latencies of the rats (p<0.05) in compare to DMSO group. The threshold of pain in the first phase of formalin test was reduced after injection of 3µg/kg of RT for two weeks. Conclusion: It was concluded that chronic i.c.v. injections of RT can induce significant hyperalgesia in rat.

In the Holy Quran, it is stated that “eating honey has healing for people” “Fihe shefaho lenas”. The word “healing” in Quran has not been used about any other food but honey and one Sura in Quran is dedicated to Nahl (bee). This study investigates the importance of honey from the perspective of Quran and medicine. This review article investigated the therapeutic properties of honey from the perspective of Quran and medicine through text analysis and manual and online search. Medicine has proven that honey due to its low moisture, high osmosis, and high acidity inhibits the growth of infectious agents and creates a sterile coat on the wound. Prophet Mohammad said, “Lam yastashfeo almariz bemasale sharbato olasal”, meaning that nothing cures the sick person the way honey does. Studies have shown that honey is effective in strengthening child development and treatment, prevention, and improvement of skin, respiratory, liver, gallbladder, eyes, ears, and nose diseases and cancer. The application of natural honey to healing diabetic and cutaneous ulcers and the topical application of honey to open wounds can accelerate the healing process. Oral administration of dates honey syrup can enhance the natural progression of delivery and womb contractions which decrease the need for cesarean. It can be concluded from the review of the literature that emphasis of Quran on the use of honey in diet and its reference to the healing property of honey for people has not been without a cause. Modern medicine also verifies the curative properties of honey for many diseases.

Background: In traditional medicine, Olive oil (Olea europaea L.) from Oleaceae family is known as a remedy for alleviating pain. This study investigates the antinociceptive effects of olive oil on male adult NMRI mice. Materials and Methods: In this experimental study, using the acetic acid-induced writhing and formalin tests, the anticipative effects of olive oil were evaluated. Olive oil (1, 5, and 10 ml/kg bodyweight), morphine (10 mg/kg bodyweight), and indomethacin (10 mg/kg bodyweight), as standard drugs, were injected intraperitoneally. The control group did not receive any treatment. Data were analyzed using one-way ANOVA and Tukey test. Results: Olive oil significantly decreased acetic acid-induced abdominal writhes (P<0.001). Olive oil could only decrease the induced pain in the second phase of the formalin test (P<0.001). Conclusion: Olive oil decreases inflammatory pain (the second phase of the formalin test and acetic acid-induced writhing tests), but it has no significant effects on neurogenic pain (the first phase of the formalin test). Further studies are required to elucidate the antinociceptive effects of olive oil.

Background: Pseudomonas aeruginosa is one of the most important causes of nosocomial infection which due to extended spectrum-beta lactamases (ESBLs) and metallo-beta lactamase (MBL) producing strains is resistant to a wide range of antibiotics. The aim of this study was to detect ESBL and MBL producing P.aeruginosa isolated from patients and investigate the effects of methanol extracts of Zataria multiflora, Myrtus communis, and Peganum harmala on them. Materials and Methods: In this experimental study, samples were obtained from 245 patients, referring to Shafa Hospital, Kerman, Iran. ESBLs producing strains were detected by double disk synergy test and phenotypic confirmatory test. In addition, E-test strips were used for MBL detection. P.aeruginosa MIC was determined for cefotaxime, ceftazidime, azteronam, imipenem, and meropenem. Methanol extracts of Zataria multiflora, Peganum harmala, and Myrtus communis plants were prepared by Agar perculation method. Results: Out of 245 patients referring to the burn unit, 120 P.aeruginosa isolates were detected from which 41 contained ESBL but they lacked MBL. 60% of isolates were resistant to cefotaxime, 66% to ceftazidime, 42% to azteronam, 3% to imipenem, and 5% to meropenem. Among the extracts, Zataria multiflora had the highest antibacterial effect on standard strains of P.aeruginosa in comparison with Peganum harmala and Myrtus communis. Conclusion: The prevalence of ESBL producing P.aeruginosa strains is high. In addition, noticing their high antibiotic resistance, utilization of herbs, such as Zataria multiflora may be considered an appropriate alternative for treatment however, more investigations are needed.
