Cinnamon ( Cinnamomum verum J. Presl) is a well - known medicinal plant considered as an effective treatment for neurological disorders based on Persian medicine . The aim of the present study was assessing the effect of cinnamon oil, cinnamic acid, and cinnamaldehyde, on the in vitro model of Parkinson's disease (PD). Cinnamon oil, prepared in sesame oil, was phytochemically analyzed using high performance liquid chromatography (HPLC). Pheochromocytoma - 12 (PC - 12) cells were treated with 1 - methyl - 4 - phenyl - 1,2,3,6 - tetrahydropyridine (MPTP) as an in vitro model of neurodegeneration in PD. Cell viability, activity of caspase enzymes, and formation of reactive oxygen sp ecies (ROS) were evaluated. MPTP significantly decreased cell viability and increased Casp activity, as well as ROS formation. Cinnamon oil and cinnamic acid at 200 µg/m L could significantly reverse MPTP - induced abnormalities in PC - 12 cells including Casp activity and ROS formation. Our study supports the beneficial effect of cinnamon oil in neurodegeneration. Furt her investigations are needed to clarify the mechanisms and main active components.

Similarities and differences between kaiy in Persian medicine and moxibustion in Chinese medicine / 中西医结合学报

Kaiy (medieval cautery) is an ancient method of heat therapy in traditional Persian medicine (TPM). Some of its important applications have been neglected during the medical revolution. Meanwhile, different treatment modalities that incorporate heat, including moxibustion, have progressed in traditional Chinese medicine. In this study, we reviewed the main TPM textbooks that were written specifically in the field of kaiy. We considered the traditional teachings in the context of contemporary information, gathered from the scientific literature about moxibustion and modern cauterization. Some surgical therapeutic indications of kaiy (e.g., debridement and coagulative procedures) have been advanced by the innovation of electro-cauterization. However, those therapeutic applications that were based on the TPM humoral theory for relieving body coldness or myofascial pains-which are similar to moxibustion usages-have not received the same attention. Apart from the broad similarities of kaiy and moxibustion as thermal therapies with similar indications, there is a striking correspondence between kaiy point mapping and acupoints. Therefore, further research on different kaiy aspects is recommended. Please cite this article as: Jaladat AM, Alizadeh Vaghasloo M, Atarzadeh F, Ayati MH, Kazemi AH, Akin E, Hashempur MH.

Among the C. colocynthis-treated groups, the one receiving 100 mg/kg power per day orally had the best treatment outcomes.@*CONCLUSION@#The present study showed that C. colocynthis fruit, through its antioxidant and hypoglycemic activities, has a positive effect in the treatment of diabetic neuropathy.

Lifestyle Recommendations for Management of Pediculosis from the Viewpoint of Persian Medicine

Introduction: Pediculosis Capitis (head lice infestation) is the most common disease of the bloodsucking insect which affects approximately six to twenty million cases and results considerable economic burden annually. In this study we aim to investigate some medieval Persian views on the role of non-pharmacological treatment strategies for prevention and control of pediculosis and compare their prescriptions with current findings. Materials and methods: In this qualitative study, we reviewed some well-known Persian medicine (PM) textbooks based on the selected keywords (Shepesh, Reshk, Ghamal and Seyban) to collect the viewpoint of PM scholars for pediculosis and its treatments. Also, we searched in the databases such as PubMed, Science direct and Scopus about the topic. Results: Persian medicine scientists believed that there are six essential health principles (SetteZaroorieh), which can affect human health and prevent diseases including air, nutrition, exercise, sleep and wakefulness, exertion of unnecessary materials from the body and finally psychological concepts. Proper management of these essential factors can improve lifestyle of people affected with pediculosis and also play a key role in prevention of head lice infestation. Conclusion: There are several suitable recommendations for prevention and control of pediculosis according to essential health principles in PM which can consider beside current drug treatments and the individual health recommendations for complete control of the disease

The Anti-melanogenesis Activities of Some Selected Brown Macroalgae from Northern Coasts of the Persian Gulf

Abstract Melanogenesis is a biological process which led to the synthesis of melanin pigment. Abnormal melanin production results in melasma, solar lentigo, post inflammatory melanoderma, etc. In this study, we examined the potential inhibitory effects of 17 brown macroalgae from Persian Gulf on melanogenesis. The effects of various concentrations (100, 250 and 500 µg/mL) of methanolic extracts of macroalgae belonging to four genera (including: Padina, Colpomonia, Cystoseira and Sargassum) were studied on oxidation of L-Dopa by mushroom tyrosinase. Subsequently, the activity of macroalgae with high inhibitory effect on monophenolase activity of mushroom tyrosinase and zebrafish was investigated using L-tyrosine as a substrate. Anti-melanogenesis effects of algae extracts were studied on zebrafish as an alternative in vivo model. Kojic acid was used as a positive control. All the tested macroalgae showed inhibitory effect on activities of diphenolase and monophenolase (of mushroom tyrosinase). P. boergesinii exhibited the most in vivo anti-tyrosinase activity compared with other samples. P. boergesenii inhibited zebrafish tyrosinase more potent than kojic acid (83% vs 50% inhibition for kojic acid). Moreover, it reduced melanin synthesis in zebrafish 42% (kojic acid: 50%).

Cytotoxic effects of Pseudocerastes persicus venom and its HPLC fractions on lung cancer cells

Several studies have pointed out that certain snake venoms contain compounds presenting cytotoxic activities that selectively interfere with cancer cell metabolism. In this study, Pseudocerastes persicus venom and its fractions were investigated for their anticancer potential on lung cancer cells. Methods: Lung cancer cells (A549) and normal fibroblast cells (Hu02) were treated with the P. persicus venom and its HPLC fractions and the cell cytotoxic effects were analyzed using MTT and lactate dehydrogenase release assays. Apoptosis was determined in venom-treated cell cultures using caspase-3 and caspase-9 assay kits. Results: The treatment of cells with HPLC fraction 21 (25-35 kDa) of P. persicus venom resulted in high LDH release in normal fibroblast cells and high caspase-3 and caspase-9 activities in lung cancer cells. These results indicate that fraction 21 induces apoptosis in cancer cells, whereas necrosis is predominantly caused by cell death in the normal cells. Fraction 21 at the final concentration of 10 μg/mL killed approximately 60% of lung cancer cells, while in normal fibroblast cells very low cell cytotoxic effect was observed. Conclusion: HPLC fraction 21 at low concentrations displayed promising anticancer properties with apoptosis induction in the lung cancer cells. This fraction may, therefore, be considered a promising candidate for further studies.(AU)

Periconceptional care and offspring health at birth and long term, from the perspective of Avicenna / 中西医结合学报

Periconceptional care such as lifestyle plays an important impact role in offspring health. The aim of the present study was to clarify the perspective of Avicenna on periconceptional care. Avicenna (980-1037 A.D.) was one of the outstanding Persian physicians, who made great contributions to the field of medical sciences, in particular, obstetrics. In advance, Avicenna's book, Canon of Medicine, was considered to find his perspectives on periconceptional care. Then, his ideas and theories were compared to the current findings by searching the keywords in main indexing systems including PubMed/MEDLINE, Scopus and Institute for Scientific Information Web of Science as well as the search engine of Google Scholar. Current investigations show that gamete quality, pregnancy outcome, and offspring health at birth and long term depend on both parents' lifestyle in pre- and periconceptional period, as well as the intrauterine environment. Avicenna believed that seminal fluid, sperm, ovum, and developing conditions in utero were influenced by the stages of food digestion and the function of some organs. On the other hand, food digestion and function of the organs also depend on each parent's lifestyle and environmental factors. He mentioned 6 principles of healthy lifestyle: exercise, nutrition, sleep and awareness, excretion of body wastes and retention of necessary materials, psychic features, as well as air and climate. Thus, a multicomponent healthy lifestyle should be considered by parents of child-bearing age in an appropriate period before and in early pregnancy as well as elimination of any disorders in parents, to give birth to more healthy offspring.

Patients were divided into 3 parallel groups that received 500 mg of placebo, dimethicone or KAASER, three times a day for 2 weeks.@*MAIN OUTCOME MEASURES@#The frequency and severity of bloating were primary outcomes, while the frequencies of eructation, defecation, borborygmus and early satiation were secondary outcomes. All parameters were evaluated at the beginning (week 0), and also weeks 2, 4 and 10 of the study, through self-report checklists with a scoring system.@*RESULTS@#Among the 84 patients who completed the study, the frequency and severity of bloating (P < 0.001), the frequencies of eructation, defecation and borborygmus (P = 0.03) were significantly improved in the group receiving KAASER (36 patients) compared with the dimethicone (35 patients) and placebo (35 patients) groups, during the 3 phases of follow-up. These significant differences persisted through the 2 and 8 weeks of follow-ups after cessation of medication (week 4 and 10). In early satiation, no significant differences were observed among the 3 groups.@*CONCLUSION@#The results showed that KAASER can be effectively used to treat patients suffering from bloating. Bloating, eructation, defecation and borborygmus in the KAASER group remained significantly improved after 2 and 8 weeks of cessation of medication, making this mechanism an interesting area for further investigation.@*TRIAL REGISTRATION@#Registration trial IRCT2015100324327N on Iranian Registry of Clinical Trials.

Holistic Approach to Functional Constipation: Perspective of Traditional Persian Medicine / 中国结合医学杂志

Traditional Persian medicine (TPM) proposes a different viewpoint to the chronic diseases. Diagnosis and implemented treatment are based on individual differences among patients. Constipation or Ea'teghal-e-batn is a condition in which the patient develops difficult or painful defecation. Based on TPM concepts, the fifirst digestion step starts from halq (oral cavity), and ends via defecation from the maq'ad (anus). Avicenna believed that four faculties, ha'zemeh (digestive), ja'zebeh (absorptive), ma'sekeh (retentive) and da'fe'eh (propulsive), are involved in the process of digestion and absorption of the ingested food and expelling the waste materials. The bowel movement and appearance of the stool is a measure for evaluating the gastrointestinal healthy function. Defecation should be with no pain and fecal material should have no burning and acuity. Low food intake or foods with dry temperament, dryness of gastrointestinal tract, diaphoresis and heavy exercise as well as intestine sensory loss were discussed as main causes of constipation. Management of constipation in TPM includes dietary schemes, oil massages and subsequently simple herbal medicines. According to TPM theories, the fifirst step in treating a disease is the elimination of disease causes (asbabe- maraz) and also providing the causes of health (asbab-e-sehhat). Health care providers should know the proper condition which the herbal medicines should be administered in and be able to guide the patients about the benefifits and hazards of herbal remedies, commonly used in their living origin.

The medieval Persian manuscript of Afyunieh: the first individual treatise on the opium and addiction in history / 中西医结合学报

According to historical evidence, the abuse of opium has been reported all over the globe-specifically throughout Eastern nations-since the sixteenth century. Before that, opium had mostly been applied as medication. Reference has been made in traditional Persian medical literature to the method of cultivation, properties, side effects and toxicity. In sixteenth century Iran, during the reign of the Safavids, opium abuse began. It was from then that prominent Persian scholars started to think of solutions to this societal problem. One of the most famous scholars was Imad al-Din Mahmud ibn Mas'ud Shirazi, who composed a book concerning addiction-Afyunieh, a comprehensive book on the topic of opium and all issues of opium. Furthermore, he recommended methods for reducing opium dose as well as substitution with other medications that had a narrower range of side effects, in order to eradicate dependency upon opium and opium-derived materials. This is most likely the first book that comprehensively addressed opium and discussed drug rehabilitation methodology, in traditional Persian medical literature. In this historical review, the authors have introduced the book Afyunieh, which presents methods for treating addiction to and giving up opium; the text comprises a synthesis of the author's opinions, professional experience and references to the work of other famous physicians.

Cross-Cultural Adaptation, Validity, and Reliability of the Persian Version of the Orebro Musculoskeletal Pain Screening Questionnaire

STUDY DESIGN: Observational study. PURPOSE: To cross-culturally translate the Orebro Musculoskeletal Pain Screening Questionnaire (OMPQ) into Persian and then evaluate its psychometric properties (reliability, validity, ceiling, and flooring effects). OVERVIEW OF LITERATURE: To the authors' knowledge, prior to this study there has been no validated instrument to screen the risk of chronicity in Persian-speaking patients with low back pain (LBP) in Iran. The OMPQ was specifically developed as a self-administered screening tool for assessing the risk of LBP chronicity. METHODS: The forward–backward translation method was used for the translation and cross-cultural adaptation of the original questionnaire. In total, 202 patients with subacute LBP completed the OMPQ and the pain disability questionnaire (PDQ), which was used to assess convergent validity. 62 patients completed the OMPQ a week later as a retest. RESULTS: Slight changes were made to the OMPQ during the translation/cultural adaptation process; face validity of the Persian version was obtained. The Persian OMPQ showed excellent test–retest reliability (intraclass correlation coefficient=0.89). Its internal consistency was 0.71, and its convergent validity was confirmed by good correlation coefficient between the OMPQ and PDQ total scores (r=0.72, p<0.05). No ceiling or floor effects were observed. CONCLUSIONS: The Persian version of the OMPQ is acceptable for the target society in terms of face validity, construct validity, reliability, and consistency. It is therefore considered a useful instrument for screening Iranian patients with LBP.
