RESUMEN

Chronic kidney disease (CKD), characterized by progressive kidney failure, significantly increases mortality and comorbidity risks such as anemia. This study contrasts the impacts of omega-3 and medium-chain triglycerides (MCT) oil on levels of iron, ferritin, total iron-binding capacity (TIBC), hemoglobin (Hb), and transferrin saturation in patients with CKD undergoing dialysis. This interventional trial was conducted on 120 patients with CKD undergoing dialysis in Rasht, Iran. For 8 weeks, the omega-3 group was orally administered three 1000-mg capsules of omega-3 fatty acid supplement, and the MCT group was administered three 1000-mg capsules containing MCT oil daily. Serum concentrations of ferritin, iron, TIBC, Hb, and transferrin saturation were assessed pre-intervention and after the intervention. There was a significant increase in serum iron levels in the MCT group compared to the omega-3 group (103.72 ± 57.8 vs. 77.48±40.13; P = 0.031). No effect was found regarding other iron-related factors such as TIBC, Hb, transferrin saturation, and ferritin levels. The results of our study indicated that taking MCT oil increased serum iron levels compared to omega-3 supplementation in patients with CKD undergoing dialysis. Further research is needed to better understand the potential benefits of MCT oils in patients with CKD.

RESUMEN

INTRODUCTION: Melanoma is still one of the deadliest cancers whose prevalence has increased in recent decades. Today, many polysaccharides and their bioactive compounds have been of special importance in modern biotechnology. They have various biological and therapeutic properties. they can regulate and strengthen the immune system, lower blood pressure and cholesterol, and reduce bacterial and viral infections. According to studies, these compounds also have antitumor properties. we investigated the cytotoxic effects of ß-Glucan obtained from solid-state fermentation (SSF) of edible medicinal mushroom Lentinus edodes on cancerous skin cells. MATERIALS AND METHODS: The mitochondria were isolated from melanoma cells via differential centrifugation and treated with various concentrations (30, 45, 60, 90, 120, and 240 µg/ml) of ß-Glucan extract. Then, they were subjected to MTT, ROS, MMP decline, mitochondrial swelling, cytochrome c release, and flow cytometry assays. RESULTS: The results of the MTT assay showed that IC50 of ß-Glucan extract was 60 µg/ml, and it induced a selectively significant (P < 0.05) concentration-dependent decrease in the SDH activity in cancerous skin mitochondria. At higher concentrations, no such effect was observed. The ROS results also showed that 30, 45, and 60 µg/ml concentrations of ß-Glucan extract significantly increased ROS. However, no such effect was observed at higher concentrations. MMP decline and the release of cytochrome c in cancer groups mitochondria and swelling were significantly increased at 30, 45, and 60 µg/ml compared to the control group. At higher concentrations, no such effect was observed. ß-Glucan extract at 60 µg/ml concentration increased apoptosis on melanoma cells, while it had no effect on control non-tumour cells. DISCUSSION AND CONCLUSION: Based on these results, ß-Glucan extract at 30, 45, and 60 µg/ml showed a cytotoxic effect, while no such effect was observed at higher concentrations. Overall, it seems that ß-Glucan has antioxidant and free radical scavenging effects on cancer cells at higher concentrations.

RESUMEN

Background and Aim: Colorectal cancer (CRC) is one of the most prevalent cancers around the world. The link between nutrients and the likelihood of developing CRC remains uncertain. The primary objective of the present study was to investigate the potential connection between dietary intake/dietary supplements and the occurrence of CRC through a literature review. Methods: A comprehensive online search was conducted in PubMed, Scopus, Web of Science, and the Cochrane Library from January 1990 to March 2023 using appropriate keywords. A systematic search was conducted for clinical trials and cohort studies in order to determine the relationship between dietary components/supplements and CRC. Results: The intake of long-chain n-3 polyunsaturated fatty acids (n-3 LCPUFAs), consisting of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), has the potential to decrease the likelihood of developing CRC (eight studies found positive effects and four studies found no association). Some other dietary components such as probiotics, prebiotics, and synbiotics may contribute to suppressing CRC development (three studies found positive effects, whereas three studies did not find any association). There is inconclusive evidence that supplementation with certain micronutrients including vitamin D (one trial found positive effects and another trial reported no association), folate, zinc, and selenium may reduce the risk of CRC. Conclusion: Some dietary supplements such as n-3 LCPUFAs and probiotics have the potential to reduce the risk of developing CRC. Further studies are necessary to validate these results and understand the underlying mechanisms.

RESUMEN

Several preclinical and clinical studies indicate that exposure to acute stress may decrease pain perception and increases pain tolerance. This phenomenon is called stress-induced analgesia (SIA). A variety of neurotransmitters, including dopamine, is involved in the SIA. Dopaminergic neurons in the mesolimbic circuits, originating from the ventral tegmental area (VTA), play a crucial role in various motivational, rewarding, and pain events. The present study aimed to investigate the modulatory role of VTA dopaminergic receptors in the antinociceptive responses evoked by forced swim stress (FSS) in a model of acute pain. One hundred-five adult male albino Wistar rats were subjected to stereotaxic surgery for implanting a unilateral cannula into the VTA. After one week of recovery, separate groups of animals were given different doses of SCH23390 and Sulpiride (0.25, 1, and 4 µg/0.3 µl) as D1- and D2-like receptor antagonists into the VTA, respectively. Then, the animals were exposed to FSS for a 6-min period, and the pain threshold was measured using the tail-flick test over a 60-min time set intervals. Results indicated that exposure to FSS produces a prominent antinociceptive response, diminishing by blocking both dopamine receptors in the VTA. Nonetheless, the effect of a D1-like dopamine receptor antagonist on FSS-induced analgesia was more prominent than that of a D2-like dopamine receptor antagonist. The results demonstrated that VTA dopaminergic receptors contribute to the pain process in stressful situations, and it might be provided a practical approach to designing new therapeutic agents for pain management.

RESUMEN

Objectives: Several lines of research have shown that hepatic fibrosis is one of the leading causes of death worldwide. Trans-chalcone is a flavonoid precursor with anti-oxidant and anti-inflammatory effects. The present study was conducted to examine the antifibrotic properties of trans-chalcone on bile duct ligation (BDL)-induced liver cholestasis in rats. Materials and Methods: Following the BDL operation, trans-chalcone at doses of 12, 24, and 50 mg/kg was administered orally once a day for 45 consecutive days. Serum levels of liver indices, including alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total and direct bilirubin, and lipid profile in addition to blood urea nitrogen (BUN) and creatinine, were measured. Additionally, catalase (CAT) and superoxide dismutase (SOD) activities were assessed in liver homogenates. Histopathological evaluations were performed using Masson trichrome (MT) and hematoxylin and eosin (H&E) staining. Results: The elevated levels of liver enzymes, total and direct bilirubin, BUN, creatinine, cholesterol, triglyceride, and low-density lipoprotein (LDL) induced by BDL were significantly reduced following trans-chalcone administration; while serum level of high-density lipoprotein (HDL) increased. Besides, treatment with trans-chalcone elevated the activities of CAT and SOD in the liver tissues of the animals with BDL surgery. According to MT and H&E staining, BDL-induced histopathological changes, including infiltration of inflammatory cells, hepatocyte necrosis, ductal hyperplasia, and collagen deposition were ameliorated using trans-chalcone administration. Conclusion: It can be concluded from the present study that trans-chalcone, possibly by its anti-oxidant and anti-inflammatory properties, may exert hepatoprotective and antifibrotic effects in BDL-induced liver fibrosis.

RESUMEN

Studies establish that the brain's Orexin system is involved in pain modulation. Orexin-1 and orexin-2 receptors (OX1 and OX2r, respectively) are essential in responsiveness to stressful stimuli. Some evidence indicates that the hippocampus's dentate gyrus (DG) potentially modulates pain and stress. The present study examined the involvement of OX1 and OX2 receptors within the DG in response to acute pain after exposure to forced swim stress (FSS). Five to seven days post-stereotaxic surgery, the baseline tail-flick latency (TFL) was taken from the animal, then rats unilaterally received through an implanted cannula either different doses of OX1r antagonist (SB334867; 1, 3, 10, and 30 nmol), OX2r antagonist (TCS OX2 29; 1, 3, 10 and 30 nmol), or vehicle (0.5 µl solution of 12% DMSO). After 5 min, rats were exposed to the FSS for six minutes. Subsequently, the tail-flick test was conducted, and the TFLs were measured at the 60-min time set intervals. Results indicated that FSS produces antinociceptive responses in the tail-flick test. Two-way ANOVA analysis showed that Microinjection of OX1r and OX2r antagonists into the DG region of the brain reduced FSS-induced analgesia in the tail-flick test. The decrement effects of these two antagonists were almost the same. Additionally, results showed that the role of both receptors was the same in modulating stress-induced analgesia (SIA). These findings show that the orexin system in the hippocampal DG region might be partially involved in the SIA in acute pain.

RESUMEN

Objective: Having cosmetic breast implants increases a woman's chance of suicide, which is now a global challenge. This systematic review evaluated the possible risk of suicide among women who undergo cosmetic breast implants. Method : This meta-analysis was done based on Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). In the current systematic review and meta-analysis, we systematically searched for all articles written in both English or Persian that estimated the prevalence of suicidal ideation in women who had cosmetic breast implants. We systematically searched different databases, including MEDLINE (PubMed), Web of Science, Embase, Cochrane, Library ProQuest, Scopus, and Google Scholar, from inception to March 2021. There was also a search for references. Suicidal ideation, a suicide plan, or suicide attempts were the outcomes. In order to determine the total pooled prevalence of suicidal ideation, we utilized a random-effects model. To examine the risks of bias in each study, we applied the Joanna Briggs Institute Critical Appraisal method. Results: We identified 218 citations in our initial search. After omitting duplicated citations and excluding irrelevant studies according to the title and abstract selection, 42 studies were chosen for the full text analysis. Finally, 11 research, examining a total of 324,332 women were incorporated into the systematic review and critical appraisal assessment. Eight of these studies were found to be eligible for meta-analysis. The frequency of suicide in women with cosmetic breast implant was 0.2% (95% CI: 0.1% to 0.4%; P < 0.001) (Q-value: 168.143, I2:95.83). Most of the included studies had moderate quality. Conclusion: There might be a correlation between cosmetic breast implants and suicide risk, which could be stronger in the presence of a history of mental illnesses. The evidence about the possible effects of breast implants on the risk of suicide is still inconclusive, and there is a need for future well-designed studies on this topic.

RESUMEN

Abstract: Rubiadin is identified as a bioactive anthraquinone that exists in some quinone rich plants. The current research was carried out to evaluate the potential anti-inflammatory impact of Rubiadin in acute and chronic inflammation test models in rodents. The anti-inflammatory activity of Rubiadin was examined in cotton pellet-induced granuloma and carrageenan-induced edema as chronic and acute inflammation models in rats. TNF- level and histopathological changes were assessed using sampled foot tissue of rat in the acute model. Also, the IL-1 level was assessed in the chronic model. One-way ANOVA (post hoc Tukeys) analysis was used for comparing the groups. Rubiadin (0.5 mg/kg, i.p.) induced a significant reduction in TNF level and the paw edema compared to the control group in carrageenan test. Also, it was observed that the anti-inflammatory activity of Rubiadin (0.5 mg/kg, i.p.) is comparable to mefenamic acid (30 mg/kg, i.p.) as the standard drug. Rubiadin was effective in granuloma induced by cotton pellet concerning the granuloma and transudate formation amount. Rubiadins anti-inflammatory effects were associated with a significant IL-1 decrease in this model. The results suggest that Rubiadin as a natural compound can possess significant peripheral anti-inflammatory impacts.


Resumo A rubiadina é identificada como uma antraquinona bioativa que existe em algumas plantas ricas em quinonas. A presente pesquisa foi realizada para avaliar o potencial impacto anti-inflamatório da rubiadina em modelos de teste de inflamação aguda e crônica em roedores. A atividade anti-inflamatória da rubiadina foi examinada em granuloma induzido por pellet de algodão e edema induzido por carragenina como modelos de inflamação crônica e aguda em ratos. O nível de TNF- e as alterações histopatológicas foram avaliados usando amostra de tecido do pé de rato no modelo agudo. Além disso, o nível de IL-1 foi avaliado no modelo crônico. A análise ANOVA de uma via (post hoc de Tukey) foi usada para comparar os grupos. A rubiadina (0,5 mg / kg, i.p.) induziu uma redução significativa no nível de TNF e no edema da pata em comparação com o grupo de controle no teste de carragenina. Além disso, foi observado que a atividade anti-inflamatória da rubiadina (0,5 mg / kg, i.p.) é comparável ao ácido mefenâmico (30 mg/kg, i.p.) como o fármaco padrão. A rubiadina foi eficaz no granuloma induzido por pellet de algodão no que diz respeito à quantidade de granuloma e formação de transudato. Os efeitos anti-inflamatórios da rubiadina foram associados a uma redução significativa de IL-1 nesse modelo. Os resultados sugerem que a rubiadina como um composto natural pode ter impactos anti-inflamatórios periféricos significativos.

RESUMEN

BACKGROUND: Compounds possessing urea/thiourea moiety have a wide range of biological properties including anticancer activity. On the other hand, taking advantage of the low toxicity and structural diversity of hydrazone derivatives, they are presently being considered for designing chemical compounds with hydrazone moiety in the field of cancer treatment. With this in mind, a series of novel ureido/thioureido derivatives possessing a hydrazone moiety bearing nitro and chloro substituents (4a-4i) have been designed, synthesized, characterized and evaluated for their in vitro cytotoxic effect on HT-29 human colon carcinoma and HepG2 hepatocarcinoma cell lines. RESULTS: Two compounds (4c and 4e) having the chloro phenylurea group hybridized with phenyl hydrazone bearing nitro or chloro moieties demonstrated potent anticancer effect with the IC50 values between 2.2 and 4.8 µM at 72 h. The mechanism of action of compound 4c was revealed in hepatocellular carcinoma cells as an inducer of apoptosis in a caspase-independent pathway. CONCLUSION: Taken together, the current work presented compound 4c as a potential lead compound in developing future hepatocellular carcinoma chemotherapy drugs. METHODS: The compounds were synthesized and then characterized by physical and spectral data (FT-IR, 1H-NMR, 13C-NMR, Mass). The anticancer activity was assessed using MTT assay, flowcytometry, annexin-V, DAPI staining and Western blot analysis.

RESUMEN

The intrinsic pain inhibitory mechanisms can be activated by fear, anxiety, and stress. Stressful experiences produce analgesia, referred to as stress-induced analgesia (SIA). Major components of the limbic system, including the ventral tegmental area, nucleus accumbens, amygdala, and hippocampus, are involved in the SIA. In this study, we tried to understand the role of dopamine receptors in the cornu ammonis area 1 (CA1) of the hippocampus in the forced swim stress (FSS)-induced analgesia. Stereotaxic surgery was unilaterally performed on 129 adult male Wistar rats weighing 220-280 g. SCH23390 (0.25, 1, and 4 µg/0.5 µl saline) or sulpiride (0.25, 1, and 4 µg/0.5 µl DMSO), as D1- and D2-like dopamine receptor antagonists, respectively, were microinjected into the CA1 area, 5 min before exposure to FSS for a 6-min period. The vehicle groups received saline or DMSO instead of SCH23390 or sulpiride, respectively. The formalin test was done using formalin injection (50 µl; 2.5%) into the plantar surface of the rat's hind paw immediately after exposure to FSS. The results demonstrated that FSS produces analgesia during the early and late phases of the formalin test. However, intra-CA1 microinjection of SCH23390 or sulpiride attenuated the FSS-induced analgesia in both phases of the formalin test. This study provides new insight into the role of D1- and D2-like dopamine receptors in the CA1 area in the FSS-induced analgesia during persistent inflammatory pain.

RESUMEN

Granulomatosis with polyangiitis disease is a rare vasculitis characterized by granulomatous inflammation of respiratory tracts and glomerulonephritis along with vasculitis of other organs. In this study, a 14- year-old boy was referred from ophthalmology clinic to the pediatric rheumatology ward due to drug-resistant conjunctivitis. He had a history of chronic rhinorrhea and nighttime coughing, and he was diagnosed with allergic rhinitis. Complete blood count showed leukocytosis and thrombocytosis, and the estimated sedimentation rate was elevated. Laboratory tests showed hematuria, proteinuria, and highly positive antineutrophil cytoplasmic antibody. Moreover, sinus computed tomography demonstrated pansinusitis, and spiral chest computed tomography showed multiple pulmonary nodules in both his lungs. Finally, based on renal biopsy, the patient was confirmed as a case of granulomatosis with polyangiitis. It is notable that acute or chronic conjunctivitis may be a manifestation of rheumatic diseases.

RESUMEN

Stress activates multiple neural pathways and neurotransmitters that often suppress pain perception, the phenomenon called stress-induced analgesia (SIA). Orexin neurons from the lateral hypothalamus project to entire brain structures such as the hippocampus. The present study examined this hypothesis that orexinergic receptors in the CA1 region of the hippocampus may play a modulatory role in the development of SIA in formalin test as an animal model of persistent inflammatory pain. One hundred-two adult male Wistar rats were administered with intra-CA1 orexin-1 receptor (OX1r) antagonist, SB334867, at the doses of 3, 10, 30, and 100 nmol or TCS OX2 29 as orexin-2 receptor (OX2r) antagonist at the doses of 1, 3, 10, and 30 nmol. Five min later, rats were exposed to forced swim stress (FSS) for a 6-min period. Then, pain-related behaviors induced by formalin injection were measured at the 5-min blocks during a 60-min period of formalin test. The current study indicated that solely stress exposure elicits antinociception in the early and late phases of the formalin test. The FSS-induced analgesia was prevented by intra-CA1 administration of SB334867 or TCS OX2 29 during either phase of the formalin test. Moreover, the contribution of the OX2r in the mediation of analgesic effect of stress was more prominent than that of the OX1r during both phases of the formalin test. It is suggested that OX1r and OX2r in the CA1 region of the hippocampus are involved in stress-induced analgesia in the animal model of persistent inflammatory pain.

RESUMEN

Abstract Insulin receptors have distributed in all brain regions, including the nucleus Accumbens (NAc), and where is implicated in the reward properties of drugs. It is well known that insulin signaling can regulate dopamine release. Therefore, in the present study, we tried to examine the effect of insulin replacement on the acquisition and expression of morphine-induced conditioned place preference (CPP) in diabetic rats. Forty-eight male Wistar rats were divided into two non-diabetic (Naïve) and diabetic groups rendered by a single injection of streptozotocin (STZ). These groups separately received insulin (10U/kg) or saline (1 ml/kg) one hour prior to morphine administration (5mg/kg;s.c.) during conditioning days (acquisition phase) or post-conditioning day (expression phase) in the CPP paradigm. In this paradigm, conditioning score (CS) and locomotion activity were recorded by Ethovision. The STZ-induced diabetic rats displayed higher CS compared to naïve rats (P<0.05). This effect was abolished in all diabetic rats that received insulin during conditioning days but not the expression phase. This study has provided evidence that insulin plays a modulatory role in morphine-induced CPP, and insulin replacement during the acquisition phase could reduce the rewarding properties of morphine in diabetes conditions through a possible modulating effect on dopamine release in the NAc region

Also, it was observed that the anti-inflammatory activity of Rubiadin (0.5 mg/kg, i.p.) is comparable to mefenamic acid (30 mg/kg, i.p.) as the standard drug. Rubiadin was effective in granuloma induced by cotton pellet concerning the granuloma and transudate formation amount. Rubiadin's anti-inflammatory effects were associated with a significant IL-1ß decrease in this model. The results suggest that Rubiadin as a natural compound can possess significant peripheral anti-inflammatory impacts.

RESUMEN

AIM: The chemokine-receptor axes play parts in development of leukemia, CXCL1, CXCL10 and CXCL12 are involved in immune responses. Thus, we have examined the serum levels of these chemokines in parallel with their related cognate receptors (CXCR1, CXCR3 and CXCR4) in AML (acute myeloid leukemia) patients prior and post BMT (bone marrow transplantation) therapy. MAIN METHODS: Clinical specimens were collected from 46 AML patients (23 M1 and 23 M3 subtypes) before/after BMT. CXCL1, CXCL10 and CXCL12 concentrations were determined by ELISA. The mRNA levels of the related receptors were detected by QRT_PCR. Data were analyzed by T-test, χ2 and ANOVA statistical methods in SPSS software version 18. A difference was regarded significant if P value < 0.05. KEY FINDINGS: Our results indicated that the elevated levels of CXCL12 in AML patients were remained unchanged after transplantation.  The CXCL10 concentration was decreased in patients. All studied chemokines were elevated in BMT patients with history of 9 times PLT transfusion. In patients who received BMT from siblings CXCL1 and CXCL10 have been elevated, whereby they were compared to patients who received BMT from parents while CXCL12 sustained unchanged in groups. Serum measures of CXCL1 and CXCL10 were induced in acute and chronic GVHD patients in compare to these without GVHD. SIGNIFICANCE: According to the results, it can be concluded that these chemokines play fundamental parts in pathogenesis of both AML and BMT. It is worthy to note that chemokines could be used as diagnostic markers alongside with possible promising therapeutic targets.

RESUMEN

Pain is a complex experience consisting of sensory, affective-motivational, and cognitive dimensions. Hence, identifying the multiple neural pathways subserving these functional aspects is a valuable task. The role of dentate gyrus (DG) as a relay station of neocortical afferents in the hippocampal formation (HF) in persistent pain is still controversial. The lateral hypothalamus (LH)-HF neural circuits are involved in numerous situations such as anxiety-like behavior, reward processing, feeding, orofacial as well as acute pain. Nonetheless, to our knowledge, the involvement of the LH-DG neural circuit in persistent pain has already remained unexplored. Adult male Wistar rats weighing 220-250 g were undergone stereotaxic surgery for unilateral implantation of two separate cannulae into the LH and DG. Intra-DG administration of the orexin-1 (OX1) and orexin-2 (OX2) receptor antagonists, SB334867 and TCS OX2 29, respectively, was performed 5 min before intra-LH microinjection of carbachol. Animals were then undergone the formalin test using 50 µl formalin injection (2.5%) into the plantar surface of the hind paw. Microinjection of SB334867 or TCS OX2 29 into the DG region attenuated the antinociceptive effect produced by carbachol microinjection into the LH. The preventive effect of SB334867 and TCS OX2 29 on intra-LH carbachol-induced antinociception was approximately equal in both early and late phases of formalin nociception. The results suggest a neural pathway from the LH to the DG, which contributes to the modulation of formalin-induced inflammatory pain through the recruitment of OX1 and OX2 receptors within the DG.

RESUMEN

Acute myeloid leukemia (AML) is defined as an aggressive disorder which is described by accumulation of immature malignant cells into the bone marrow. Chemokine-receptor axes are defined as factors involved in AML pathogenesis and prognosis. The chemokine receptor CXCR4 along with its ligand, CXCL12 fit in important players that are actively involved in the cross-talk between leukemia cells and bone marrow microenvironment. Therefore, according to the above introductory comments, in this review article, we have focused on delineating some parts played by CXCL12/CXCR4 axis in various aspects of AML malignancy. Targeting both leukemic and stromal cell interaction is nowadays accepted as a wide and attractive strategy for improving the outcome of treatment in AML in a non-cell autonomous manner. This strategy might be employed in a wide variety of AML patients regardless of their causative mutations. In addition to several potential targets involved in the disruption of malignant leukemic cells from their specific protective niches, compounds which interfere with CXCL12/CXCR4 axis have also been explored in multiple early-phase established clinical trials. Moreover, extensive research programs are exploring novel leading mechanisms for leukemia-stromal interactions that appear to find out novel therapeutic targets within the near future.

RESUMEN

AIMS: AML (Acute myeloid leukemia) is characterized as a heterogeneous cancer. Chemokines play fundamental roles in the onset, progression cellular, migration, survival and improvement of AML therapy outcomes. The CCR5 receptors together with their ligands have indirect effects on the progression of cancer. In the present study, we have decided to investigate the impact of chemotherapy on the expression of CCR5 and its related ligands (CCL5, CCL4 and CCL3). MAIN METHODS: In this study, peripheral blood and bone marrow specimens were collected prior and post the first stage of (7 + 3) chemotherapy from 25 AML-M4/M5 patients. The expression of CCR by Lymphocytes in peripheral blood was examined by flow cytometry and QRT-PCR. The serum levels of chemokines were measured by ELISA. KEY FINDINGS: There was not observed leukemic blast cells in peripheral blood smear at post first stage of chemotherapy. We found that the expression of CCR5 was attenuated in patients post the first stage of chemotherapy and the healthy control subjects. We have also observed that the serum levels of chemokines were elevated in AML patients prior to chemotherapy. Although in post-chemotherapy stage, only CCL3 was found to reach to the baseline level, CCL5 and CCL4 have not returned to the basal level and were significantly higher than healthy control subjects. SIGNIFICANCE: The current chemotherapy protocol was not able to completely inhibit CCL5 and CCL4. In conclusion, our findings in harmony with previous studies suggest that inhibition of chemokines along with chemotherapy in AML patients may aid therapy.

RESUMEN

Tanacetum balsamita locally called Shahesparam is an aromatic plant that grows widely in Azerbaijan Province, Iran. Due to the widespread use of T. balsamita as a pain killer and relief of inflammatory based disorders in Iranian folk medicine and considering the high content of essential oil in T. balsamita aerial parts, we were prompted to investigate the anti-nociceptive and anti-inflammatory properties of T. balsamita essential oil (TBEO) for the first time. The carrageenan-induced Paw Edema was used for inflammation evaluation in rat, and hot-plate method was used for pain assessment in mice. Different doses of TBEO were administered. Morphine and Mefenamic acid were used as the standard drugs in anti-nociceptive and anti-inflammatory evaluation tests, respectively. TBEO (100 mg/kg) showed significantly anti-nociceptive activity in hot-plate test. The anti-inflammatory activity of TBEO was found to be more than mefenamic acid. The studied oil was analyzed by GC and GC-MS. The major component of the oil was characterized as carvone (39.8%) which might be responsible for the observed activities. The results suggested that TBEO possessed biologically active constituents that had significant analgesic and anti-inflammatory effects which support the ethno-medicinal claims of the plant application in the management of pain and inflammation.
