Dear editor In recent years, the number of scientific research papers of Iranian scientists has substantially grown in national and international journals that indicates particular attitude of Iranian scientific community to the development of knowledge in different fields. Moreover, improvement of quality of scientific papers is necessary. For this purpose, criticism of published studies is a way to increase the quality of articles and make them clear. In Avicenna Journal of Phytomedicine, volume (5), issue (2), year 2015, an article entitled “Effects of aqueous extract of celery (Apium graveolens L.) leaves on spermatogenesis in healthy male rats” was published and the papers like this should be appreciated. However, the paper has some drawbacks which if not resolve, could be misleading for researchers who tend to use it or do research in its direction. So, with all due respect to the research team, we decided to evaluate the paper ambiguities in order to improve the quality of future articles.

Seed of Descurainia sophia Webb ex Prantl has been traditionally prescribed as treatment for palpitation, varicose vein, varicocele, constipation, hemorrhoid, skin eruptions, and impotence. To outline a view for further approaches, current work compiled a survey on all relevant clinical properties of this medicament in addition to the traditional reports. To do this, databases as PubMed, Scopus, EMBASE, IranMedex and Science information databases (SID) were searched by keywords, i.e., “Descurainia sophia”, “Khaksheer”, and “Flixweed” as well as “pharmacology” and “phytochemistry”. According to the findings, scant experimental evaluation and clinical assessment have been performed on this medicament. Of those, only anti-inflammatory, analgesic, and antipyretic effects as well as antioxidant and anthelmintic activities were assessed and confirmed in experimental studies. Despite broad administration of this herb in folk and traditional medicine, only two human clinical trials in bowel discomfort and pregnant subjects were conducted. Taken as a whole, more comprehensive clinical evaluations should be conducted on respective applications to support those traditional and folk uses.

Objective: In this study, we aimed at evaluation of the efficacy of Hypericum perforatum and flaxseed on hot flash, vaginal atrophy and estrogen-dependent cancers in menopausal women
Materials and Methods: We searched MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials (RCT) to explore trials that assessed the effectiveness of H. perforatum and flaxseed on hot flash, vaginal atrophy and estrogen-dependent cancers. In this regard, the following terms were used “menopause AND H. perforatum OR flaxseed OR Linum usitatissimum. Only randomized controlled trials were included in the study.
Results: Nine RCTs were included in this systematic review. Based on the literature, flaxseed showed beneficial effect on hot flash frequency and intensity, which was not statistically significant. According to two trials, flaxseed showed estrogenic effects; however, no conclusion regarding cancer promoting or protecting effects can be made. The evidence of the efficacy of the flaxseed on alleviating vaginal atrophy was also limited due to inconsistent findings in this regard. One trial declared that Vitex agnus-castus and H. perforatum showed comparable decrease in the frequency of hot flashes.
Conclusion: The results of our systematic review suggest beneficial effect on vasomotor symptom with both of flaxseed and H. perforatum. Consistent conclusion regarding estrogen-dependent cancers and maturation value is limited due to small number of trials related to flaxseed. Further trials are still needed to confirm the results of our systematic review.

Objective: To validate the ethno-therapeutic claim of the traditionally used plant Jasminum auriculatum (J. auriculatum) in skin diseases, by evaluating its wound healing potential along with its antioxidant and antimicrobial properties; so as to understand their role in wound healing. Materials and Methods: Excision and incision wound models were used to evaluate the wound healing activity on albino rats. The wound healing potential was assessed by measuring rate of wound contraction, epithelialization period, hydroxyproline content, skin breaking strength and histopathological parameters. Reference standard drug was Nitrofurazone ointment. The antioxidant activity was determined using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) method. The antimicrobial activity was determined by agar well diffusion method and minimum inhibitory concentration by serial dilution method. Results: Higher rate of wound contraction (83.66±0.50% on 15th day), decrease in the period of epithelialization (17.83±1.6days), higher skin breaking strength (170.71±1.52g), higher collagen content and favourable histopathological changes revealed that topical application of ointment containing successive ethanolic extract (S.E.E) of J. auriculatum leaves has the most potent wound healing ability compared to control group in both the models studied. The DPPH radical scavenging activity of successive ethanolic extract was found to be 33.39µg/ml. Successive ethanolic extract was found to be most effective against Pseudomonas auregenosa having a zone of inhibition 16.65±0.6mm and the minimum inhibitory concentration was 0.78mg/ml. Conclusion: The data of this study indicate that successive ethanolic extract of the leaves exhibit potent wound healing, antioxidant and antimicrobial properties. This justifies the ethno-medicinal use of plant for the treatment of wound and microbial infections.

Objective: Regarding the anticonvulsant effects of Satureja hortensis (S. hortensis) in Avicenna’s book: canon of medicine; the present study was undertaken to evaluate the anti- eplileptic effects of S. hortensis aqueous and ethanolic aerial part extracts. Furthermore, the mechanisms of their anticonvulsant activities were also evaluated.
Materials and Methods: Seizure was induced by Pentylentetrazol (PTZ) and MES (maximal electroshock) models. Mice were randomly divided into 8 groups; negative control (normal saline, 10ml/Kg), positive control (diazepam, 2 mg/kg), S. hortensis aqueous and ethanolic extracts (200, 400 and 600 mg/kg). In PTZ test, latency to the first minimal clonic seizure (MCS), latency to the first generalized tonic–clonic seizures (GTCS), the total duration of seizures and protection against mortality were evaluated. In MES test, the stretching length of extremities and protection against mortality were recorded.
Results: Aqueous and ethanolic extracts (400 and 600 mg/kg) significantly increased MCS and GTCS latencies in PTZ model. Three doses of the extracts decreased the total duration of seizure. These extracts did not show any protective effects on seizure induced by MES model. In PTZ model, flumazenil, an antagonist of benzodiazepine (BZD) site in the GABAA-BZD receptor complex and 7- nitroindazole (7- NI), a selective nNOS (neuronal nitric oxide synthase) inhibitor, reduced the prolongation of seizure latency.
Conclusion: S. hortensis showed anticonvulsant activity in PTZ model and this effect may be mediated, at least partly, through interacting with nitric oxide and GABAA-BZD receptor complex.

Objective: Determination and comparison of the effect of infusion time on the antioxidant activity and total polyphenol contents of bagged and loosely packed black teas. Materials and Methods: For twenty loosely packed and eleven bagged tea samples, the antioxidant activity and total polyphenol content were analyzed using FRAP and Folin-Ciocalteau methods, respectively. The ANOVA with Tukey post-hoc test and independent t-test were used for statistical analysis. Results: The antioxidant activity and polyphenol content of various brands of tea samples were significantly different. There were significant differences in the antioxidant activity of loosely packed teas between 5, 15(p=0.03), 30(p=0.02) and 60(p=0.007) minutes of brewing times. Besides, there was a significant difference in antioxidant activity of bagged samples infused for 1 minute with four other infusion time points (p<0.001). In the case of polyphenol content, in loosely-packed tea samples, there were not significant differences between different brewing times (p=0.15). However, in bagged samples, the polyphenol contents of samples that were brewed for 1 minute were significantly lower than samples brewed for 3, 4, and 5 minutes (p<0.05). The antioxidant activity and polyphenol content of tea bags were significantly higher than those ofloosely-packed forms of the same brands at 5-min of brewing time (p<0.001). Conclusion: The infusion time and the form of tea (loosely packed or bagged) were shown to be important determinants of the antioxidant activity and polyphenol content of black tea infusions in addition to the variety, growing environment and manufacturing conditions.

Objective: Pimpinella anisum (P. anisum) has different pharmacological properties such as anticonvulsant, analgesic, tranquilizer, antidepressant and anti-anxiety effects. In this study the antidepressant-like effect of aqueous and ethanolic extracts of P. anisum fruit in mice was investigated.
Materials and Methods: Forced swimming test (FST) and tail suspension test (TST) were used to determine the antidepressant effects of P. anisum (50, 100 and 200 mg/kg, i.p.) fruit extracts. Fluoxetine (20 mg/kg, i.p.) and imipramine (30 mg/kg, i.p.) were used as standard drugs.
Results: All the three doses of aqueous and ethanolic extracts (except 50 mg/kg of aqueous extract in FST) significantly and dose-dependently reduced the immobility times in both FST and TST. All doses of extracts increased the swimming time dose-dependently, without any significant change in climbing time. In addition, all doses of ethanolic extract reduced immobility times and increased swimming time insignificantly higher than aqueous extract. But, the two extracts decreased the duration of climbing time similarly. Fluoxetine and imipramine decreased immobility time in both tests. Fluoxetine increased the swimming time without modifying climbing time. In contrast, imipramine increased climbing time without any significant change in swimming time.
Conclusion: The results of this study suggest that P. anisum possesses an antidepressant-like activity similar to that of fluoxetine, which has a potential clinical value for application in the management of depression.

Objective: Irinotecan is a botanical derivative and an anti-cancer drug with cytotoxic and genotoxic effects. The present study evaluated the effect of Lactobacillus plantarum A7 on the genotoxic activity of irinotecan in a hepatocellular carcinoma cell line (HepG2) by comet assay. Materials and Methods: HepG2 were incubated with irinotecan (100 µM), heat-killed cells (0.025 µg/ml) + irinotecan (100 µM), and cell-free supernatants (0.5 and 1 µg/ml) of L. plantarum A7 + irinotecan (100 µM). Phosphate buffered saline (PBS) was used as negative control. Results: Irinotecan was shown to induce DNA damage in HepG2 cells. The results showed that heat-killed cells (0.025 µg/ml) and cell-free supernatants (0.5 and 1 µg/ml) of L. plantarum significantly reduce irinotecan- induced DNA damage. Conclusion: Our results indicate that L. plantarum A7 can decrease the genotoxic effects of irinotecan in HepG2 cells, in vitro. This finding may be supportive for the optimization of therapeutic efficacy in irinotecan treatment.

Objective: There are few therapeutic options for treatment of multidrug resistant Klebsiella pneumoniae isolates as a hospital infectious agent (nosocomial infection). The aim of this study was to evaluate the antibacterial activity of Zataria multiflora Boiss extracts against ESBL-producing Klebsiella pneumoniae strains. Materials and Methods: This study was conducted on 100 K. pneumoniae isolates from two hospitals in Tehran, Iran. Antibiotic susceptibility tests were performed by Kirby-Bauer disc diffusion and microdilution broth methods and detection of ESBL was carried out according to CLSI guidelines. The blaCTX-M-15plasmid genewas detected by PCR and sequencing methods. Extracts susceptibility test was performed by broth microdilution method. Results: Among 100 K. pneumoniae strains, 48 (48%) were ESBL positive. In this study, fosfomycin, colistin and tigecycline were more active than other antibiotics. The existence of blaCTX-M-15 was detected in 30 (62.5%) of 48 ESBL-producing isolates. The chloroformic extract showed potent activity against ESBL-producing K. pneumoniae strains (MIC50 = 1.56 mg/ml and MIC90=3.12mg/ml). The MIC50 and MIC90 (The MIC50 represents the MIC value at which ≥50% of the isolates in a test population are inhibited and the MIC90 represents the MIC value at which ≥90% of the strains within a test population are inhibited) were 3.12 and 6.25 mg/ml and 6.25 and 12.5 mg/ml for methanolic and acetonic extracts, respectively. Conclusions: The incidence of ESBL-producing K. pneumoniae is very high. Therefore, detection of ESBL-producing K. pneumoniae isolates is of great importance in identifying drug resistance patterns in K. pneumoniae isolates and in control of infections. Zataria multiflora may have the potential to be used against multidrug resistant organisms such as clinical isolates of ESBL-producing K. pneumoniae.

Objective: Scientificstudies have shown that Vitis vinifera (V. vinifera) contains flavonoids and stillbenoids. Flavonoids are well known to possess anxiolytic activities. In view of the idea that flavonoids present in V. vinifera could be useful in anxiety, we evaluated anxiolytic-like activity of V. vinifera juice (VVJ). Materials and Methods: Light/dark box and the open field test were used to assess the anxiolytic potential of V. vinifera juice (VVJ). The juice was given orally by gavage at the dose of 4 and 8 mL/kg body weight. Diazepam (1 mg/kg i.p.) was used as the standard drug. Results: It was observed that the juice produced significant and dose dependent increase in the time spent in light cubicle (p<0.001), transfer latency from the light to dark cubicle (p<0.001) and the number of transitions between the two cubicles (p<0.001) as compared with the control group. V. vinifera also demonstrated significant and dose dependent increase in ambulation (P<0.001) and rearing (p<0.001) in open field test as compared to the control group. Conclusion: In conclusion, the present study establishes the anxiolytic-like activity of VVJ in animal models of anxiety.

Objective: Rice Bran Oil (RBO) is extracted from the outer layer of rice. Little information is available regarding its safety. The present study was conducted to assess its safety in chicken embryo model. Materials and Methods: RBO was injected on day 4 of incubation of chickens. The tissues and serum samples were collected. Oxidative stress parameters in the liver, kidney and brain and biochemical parameters of serum were measured. The deformities were also investigated. Results: The changes in the liver enzymes activity were not statistically significant. There was significant decrease and increase in lipid peroxidation and glutathione level, respectively. It is suggested that RBO is a natural antioxidant source. Low-density lipoprotein cholesterol (LDL) also decreased. No abnormal findings were observed in the chickens. Conclusion: No toxic effect was observed following RBO administration in chicken embryos. This study showed that RBO is not a safety concern.

Objectives: The objective of this research was to investigate the chemical composition and antibacterial activities of the fatty acids and essential oil from various parts of Ligularia persica Boiss (L. persica) growing wild in north of Iran. Materials and Methods: Essential oils were extracted by using Clevenger-type apparatus. Antibacterial activity was tested on two Gram-positive and two Gram-negative bacteria by using micro dilution method. Results: GC and GC∕MS analysis of the oils resulted in detection of 94%, 96%, 93%, 99% of the total essential oil of flowers, stems, roots and leaves, respectively. The main components of flowers oil were cis-ocimene (15.4%), β-myrcene (4.4%), β-ocimene (3.9%), and γ-terpinene (5.0%). The major constituents of stems oil were β-phellandrene (5.4%), β-cymene (7.0%), valencene (3.9%). The main compounds of root oil were fukinanolid (17.0%), α-phellandrene (11.5%) and Β-selinene (5.0%) and in the case of leaves oil were cis-ocimene (4.8%), β-ocimene (4.9%), and linolenic acid methyl ester (4.7%). An analysis by GC-FID and GC-MS on the fatty-acid composition of the different parts of L. persica showed that major components were linoleic acid (11.3-31.6%), linolenic acid (4.7-21.8%) and palmitic acid (7.2-23.2%). Saturated fatty acids were found in lower amounts than unsaturated ones. The least minimum inhibition concentration (MIC) of the L. persica was 7.16 μg/ml against Pseudomonas aeruginosa. Conclusion: Our study indicated that the essential oil from L. persica stems and flowers showed high inhibitory effect on the Gram negative bacteria. The results also showed that fatty acids from the stems and leaves contained a high amount of poly-unsaturated fatty acids (PUFAs).
