background: previous studies have reported the antifertility activities of sulfonamides. this study was designed to evaluate the effects of co-trimoxazole and its co-administration with folic acid on ovarian tissue in female rats. methods: a total of 54 rats were randomly divided into 9 groups (n=6) . group i served as the control and group ii (vehicle) received saline. other groups, iii to ix,...

objectives: the purpose of this experimental study was to evaluate the efficacy of low level laser therapy (lllt) for pain reduction after midpalatal expansion in rats.   materials and methods: sixty male sprague six-week old rats weighing 180±10g were divided into seven groups (two experimental groups of 24 rats and one control group of 12 rats). the experimental groups were subjected to expan...

accelerating wound healing is now considered as a principle clinical treatment and increasing the quality and speed of healing which has always been emphasized by the scientists. propolis and honey are natural bee products with wide range of biological and medicinal properties. this study was aimed to determine the synergistic effect of honey and propolis in wound healing of rat skin. a total o...

objective(s): crocin influences many biological functions including memory and learning. the present study was aimed to investigate the effects of crocin on learning and memory impairments in streptozotocine-induced diabetic rats. materials and methods: diabetes was induced by intraperitoneal (ip) injection of streptozotocin (stz, 45 mg/kg). transfer latency (tl) paradigm in elevated plus-maze ...

depressive disorders are more common among persons with chronic diseases such as inflammatory bowel disease and anti-inflammatory effect of some antidepressants such as amitriptyline has been reported. acetic acid colitis was induced in both reserpinised (depressed) and non-reserpinised (normal) rats. reserpinised groups received reserpine (6 mg/kg, i.p.) one hour prior to colitis induction. th...

previous studies have shown that ascorbic acid (aa) plays a crucial role in mammalian brain as avitamin and neuronal modulator. there is increasing evidence indicating that dopaminergic system and aacould affect learning and memory processes. in addition, vitamin c acts as a dopamine antagonist in thebrain. the aim of the present study was to evaluate the intra-hippocampal co-administration of ...

conclusions our findings suggest that the analgesic effect of hrcle may be mediated via both peripheral and central mechanisms. the presence of flavonoids might be responsible for the anti-nociceptive activity of this plant. results hrcle significantly inhibited the number of contractions induced by acetic acid in the writhing test at all doses, while anti-nociceptive activity was only shown at ...

excessive scarring; paralleling the process in tendon reconstruction of the hand. inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. methods:  thirty female rats (~200 g) were randomly distributed into two groups (n=15...

the present study investigated the effects of intra-dentate gyrus microinjection of naloxone (an opioid antagonist) and thioperamide (an antagonist of histamine h3 receptors) in the formalin test in rats. subcutaneous injection of formalin (50 μl, 2.5 %) in the ventral surface of right hind paw produced a biphasic pattern (first phase: 0-5 min and second phase: 15 - 60 min) of licking/biting an...

Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder with disrupted uterus structure and function. A positive effect of vitamin D3 (VD3) in female reproduction was observed. Chemerin (RARRES2) adiponectin (ADIPOQ) are the main adipokines whose levels altered PCOS patients. Therefore, aim this study to investigate impact VD3 supplementation on RARRES2 ADIPOQ rats. Methods: We an...
