Long-term pulmonary functional status following coronary artery bypass grafting surgery

BACKGROUND: The present study aimed to describe the long-term alterations of pulmonary function and also to describe its association with post-operative pain after coronary artery bypass grafting (CABG) surgery. METHODS: In this prospective study, thirty non-smoker male patients undergoing isolated on-pump CABG were consecutively included in this study. Pulmonary function measurements were performed, in a sitting position, preoperatively, a week postoperatively, and 6 months after the surgery using a Medical Graphics PF/Dx pulmonary function system. Pain was determined by using visual analog scale (VAS) pain scores with a standardized questionnaire's. RESULTS: Regarding functional class, all patients had New York Heart Association (NYHA) Class II to III. A week after operation, a severe restrictive pulmonary impairment was revealed with a mean decrease in VC to 60.9 +/- 9.2% and in forced expiratory volume in one second (FEV1) to 64.6 +/- 12.2% of pre-operative values (P < 0.001). Regarding sternotomy related pain, the mean pain VAS score was preoperatively 3.3 +/- 1.5 that reached to 6.2 +/- 2.5 and 4.8 +/- 2.2 1 week and 6 months after the operation (P < 0.001). The trend of the changes in pain score within 6 months of operation was significantly similar to the trend of the changes in some pulmonary function indices such as FEV% and residual volume (RV). CONCLUSION: A significant reduction is expected in most pulmonary functional parameters following CABG despite normal pulmonary function state preoperatively. Severe pain originated from sternotomy may be an important factor related to pulmonary dysfunction following CABG

Is herbal therapy safe in obesity? A case of apium graveolens (Celery) induced hyperthyroidism

BACKGROUND: Apium graveolens is one of the well-known herbs used for the treatment of different; however, allergic reactions have been reported after its use. This report aimed to demonstrate the A. graveolens induced hyperthyroidism after its oral consumption for weight loss. CASE REPORT: Mr. A, 48-year-old, with no history of any thyroid diseases, was diagnosed with hyperthyroidism due to daily consumption of 4 g of dried celery leaves for 45 days. After cessation of consumption and treatment with methimazole, the symptoms remitted. Then, the medication was discontinued when the lab tests and ultrasound were normal and indicated the patient’s definite recovery. In 2 months follow up of, he was normal and thyroid-stimulating hormone (TSH), T4, T3, anti-TSH receptor, anti thyroperoxidase and antithyroglobulin were in normal ranges. CONCLUSION: Hyperthyroidism may be induced by consumption celery. Although many studies have reported side effects such as allergic reactions for this herb, this is the first report of hyperthyroidism induced by celery in which the patient recovered after discontinuing the medication. Therefore, it can be assumed that celery induces hyperthyroidism as a side effect of this herb if it is used for a long term. © 2016,.Isfahan University of Medical Sciences(IUMS).

Use of lipid-lowering medicinal herbs during pregnancy: A systematic review on safety and dosage

BACKGROUND: Hyperlipidemia is one of the important diseases in pregnancy that causes fetal abnormalities during pregnancy and after the birth. Unfortunately, the usual anti-fat drugs are associated with high morbidity in fetus and due to people's inclination towards taking herbs, it is required to identify side effects of medicinal herbs in pregnancy. The aim of this study was to present hypolipidemic herbs that would not any complications for mother and fetus. METHODS: In this review article, the major electronic databases such as EBSCO, Central Register of Controlled Trials (CENTRAL), China Network Knowledge Infrastructure (CNKI), Cochrane, Google scholar, MEDLINE, SciVerse, Scopus, and Web of Science were searched using the key words “herbal” and “hyperlipidemia”, “herbal” and “pregnancy” matched by MeSH from their respective inceptions till September, 2016. Total of 1723 publications (145 review articles, 855 original research articles, and 723 abstracts) about the effect of herbals on hyperlipidemia and 682 publications (200 abstracts, 423 original research articles, and 59 review articles) about the effect of herbals in pregnancy were retrieved. At the end, a list of medicinal plants effective on hyperlipidemia alongside their effects on pregnancy was developed. Finally, the plants effective on hyperlipidemia and safe during pregnancy were determined and their dosage, complications, mechanism of action, and side effects were reported. RESULTS: A total of 110 effective herbs on hyperlipidemia were identified and complications of 95 plants in pregnancy were studied. At last, among the 55 selected plants effective on hyperlipidemia and examined for pregnancy, we reported 12 herbs with their dosage and special considerations that can be used to treat hyperlipidemia during pregnancy. CONCLUSION: Some medicinal plants can be used to treat hyperlipidemia during pregnancy without any significant side effects both on mother or fetus

Systematic review on safety and drug interaction of herbal therapy in hyperlipidemia: a guide for internist.

Because of reporting high side effects related to biosynthetic drugs, recent attention has been paid to the use of herbs instead of chemical drugs to balance serum lipids. The present systematic review aimed to evaluate the safety of herbal medicines and also to assess drug interaction in herbal therapy in treating hyperlipidemia. The international research databases including MEDLINE; Google scholar, Web of Science SciVerse Scopus (SCOPUS); EBSCO Academic Search; Cochrane Central Register of Controlled Trials (CENTRAL); and a Chinese database (China Network Knowledge Infrastructure [CNKI]) were searched from their respective inceptions up to September 2014 with the search terms of "hyperlipidemia", "herbal medicine", "medicine traditional", "extract plant", "Traditional Medicine" and "Chinese Herbal Medicine" without narrowing or limiting search elements. A total of 85 randomized clinical trials (RCTs) studies were finally assessed on human subjects. A notable number of herbal drugs that are commonly used as an anti-hyperlipidemia agent may be interacted with a variety of biosynthetic drugs. In this regard, the most common reported herb-drug reactions were related to anticoagulants, antidepressants, anti-epileptic, anti-inflammatory, and/or even antihypertension and anti-lipidemic drugs. Also, a considerable number of anti-lipidemic drugs of plants origin may be accompanied with metabolic disturbances and serious complications within pregnancy and breast feeding. The main fundamental principles for administration of these drugs include physicians' complete awareness of the effects and interactions of these drugs, educating people not taking these drugs arbitrarily, and closely monitoring the verification and distribution of the drugs in the society

Effect of scientific principles of gavage feeding in oral medicine administration on knowledge and function of nurses in intensive care unit (ICU)

Medication through an enteral feeding tube is one of the main cares in patients hospitalized in the intensive care unit continuously being a challenge. Correct delivery of medication through an enteral feeding tube requires specific knowledge and skills in this field. The nurse as the main responsible for administering a drug, has a very important role in this regard. This study was carried out as a quasi-experimental study on 90 cases of ICU nurses. First, using a questionnaire (pretest), the level of knowledge and practice in intensive care unit was measured. The training course for speech, along with a pamphlet and face to face, was held and again after a month their awareness and performance was measured by questionnaire (post-test).For analysis of data, SPSS software (version 21) and paired tests and chi-square was used. Results showed the mean score of nurses' knowledge prior to applying scientific principles (12/9889 ±2/04167) and their knowledge after that (19/3333±0/71893); mean performance score prior to applying scientific principles was significantly difference with the average score of their next performance (P=0/0001). Also results indicated that the average of all subscales of knowledge and practice (preparation, dosage forms, thumbs up and tubal obstruction, drug interactions and side effects) significantly increased after the application of scientific principles (P=0/0001). This study showed that the application of scientific principles in accordance with the instructions provided, significantly increases knowledge and practice of nurses

The first record of Philometra rischta (Nematoda: Philometridae) in Blicca bjoerkna of Anzali wetland, Iran

The aim of the present study was to report Philometra rischta from Blicca bjoerkna from the Caspian Sea. During this study, from August (2008) to April (2009), 78 fish specimens were collected and transferred to the aquatic research laboratory of Shahid Beheshti University and were examined for parasitic infection. Parasites were fixed in formalin (10%). The parasites were indentified according to standard keys (Moravec, 1994, 1998). Prevalence (total of infected fish per total of fish) and mean intensity (number of parasite per total of infected of fish) were calculated for this parasite

Variable DNA methylation of transposable elements: The case study of mouse Early Transposons

Phenotypic variation stems from both genetic and epigenetic differences between individuals. In order to elucidate how phenotypes are determined, it is necessary to understand the forces that generate variation in genome sequence as well as its epigenetic state. In both contexts, transposable elements (TEs) may play an important role. It is well established that TE activity is a major generator of genetic variation, but recent research also suggests that TEs contribute to epigenetic variation. Stochastic epigenetic silencing of some TE insertions in mice has been shown to cause phenotypic variability between individuals. However, the prevalence of this phenomenon has never been evaluated. Here, we use 18 insertions of a mouse Endogenous Retrovirus (ERV) family, the Early Transposons (ETns), to detect insertion-dependent determinants of DNA methylation levels and variability between both cells and individuals. We show that the structure and age of insertions influence methylation levels and variability, resulting in a subgroup of loci that displays unexpectedly high variability in methylation and suggesting stochastic events during methylation establishment. Despite variation in methylation according to the age and structure of each locus, homologous CpG sites show similar tendencies in methylation levels across loci, emphasizing the role of the insertion's sequence in methylation determination. Our results show that differences in methylation of ETns between individuals is not a sporadic phenomenon and support the hypothesis that ERVs contribute to phenotypic variability through their stochastic silencing

Distribution of zooplankton in the southern Caspian Sea

The zooplanktons were studied in spring, autumn and winter in the southern Caspian Sea in 1996. Sampling carried out in four season. In each season, 180 specimens were identified and their frequency calculated per m^3. 55 species of zooplanktons were identified including 55% Cladocera, 15% Copepoda and 11 % Rotatoria, 9% other groups such as meroplanktons. The maximum species diversity was observed for Cladocera and the maximum frequency were observed for Copepoda. The Copepoda affected on abundance of zooplanktons as this frequency included in spring, summer, autumn and winter that were 38% to 97%, 22% to 92%, 71 % to 99% and 31 % to 92%, respectively. In summer, the Copepoda and lamellibranchiata larvae had main role in formation of zooplankton population in western region of the southern Caspian Sea, but in autumn, 70% of zooplankton population were copepods. The frequency of zooplanktons in spring, summer, autumn and winter were calculated 4081 to 20143; 7812 to 65741; 10850 to 34406 and 4510 to 20576 inch/m^3, respectively. The maximum biomass was observed during summer with 200 mg/m^3
