Background: Momordica charantia has some hypoglycemic properties.Objective: The purpose of the present study was to find out the impact of Momordica charantia (karela) on the proportion of hepatocytes in the  Streptozotocin-induced  diabetic  rats.Methodology: This  was  an  animal  study  carried  out  in  the Department of Anatomy at Bangabandhu Sheikh Mujib Medical University (BSMMU) and Bangladesh Institute of Research & rehabilitation in Diabetes, Endocrine & metabolic Disorders (BIRDEM), Dhaka. Healthy young Long Evans rats of male sex weighing 150 to 280gm with an age range of 10 to 12 weeks were used in this study. The rats were divided into 4 equal groups depending upon their different sorts of dietary feedings and drug treatment. The variation of different proportion of hepatocytes with intranuclear inclusions in different groups of rat was monitored.Result: Sixty five rats were included in this study. Mean proportion of hepatocytes with intranuclear inclusions on day 51 from Streptozotocin/vehicle injection in the control group which was known as Group-A was 0. In untreated diabetic group the mean proportion of hepatocytes with intranuclear inclusions was 3.71 ± 0.82. On the other hand, in the insulin-treated diabetic rats the mean proportion of hepatocytes with intranuclear inclusions was 0 and in the karela-treated diabetic rats, the proportion of hepatocytes with intranuclear inclusions was 0. The value in the insulin-treated diabetic rats (p=0.0001) and in the karela-treated diabetic rats (p= 0.0001) were significantly lower than that of the untreated diabetic rats; however, there was no significant difference between the insulin-treated diabetic rats & the karela-treated diabetic rats (P>0.05) in this regard.Conclusion: Karela showed a tendency of acting against hyperglycemic effects of Streptozotocin-induced diabetes mellitus and also acting against the rise in proportion of hepatocytes with intranuclear inclusions in Streptozotocin-induced diabetes mellitus.DOI: http://dx.doi.org/10.3329/jssmc.v5i2.20761J Shaheed Suhrawardy Med Coll, 2013;5(2):84-86

The  present  experimental  study  was  conducted  to  investigate  whether  Momordica  charantia  (karela)  has  got  any  impact  on  serum  aspartate  aminotransferase  (AST)  level  in  the  streptozotocin induced diabetic rats. Sixty healthy young Long Evans rats of male sex weighing  150 to 280 gm aged between 10 to 12 weeks were used in this study. The rats were divided into  4 equal groups depending on their different sorts of dietary feedings and drug treatment. Serum  AST level was estimated in all rats up to day 51 from the day of streptozotocin/ vehicle injection.  The mean ± SD of final serum AST level as percentage of corresponding initial level (value on  51st day  to  the  value  on  7th day) was  95.1  ±  13.4  u/L  in  healthy  rats,  110.0  ±  7.6  u/L  in  the  untreated diabetic rats, 39.4 ± 10.1 u/L in the insulin-treated diabetic rats and 109.5 ± 23.8 u/L  in  the  karela-treated  diabetic  rats. The AST percentage  change  value  of  diabetic  rats  on  51st  day  corresponding  to  the  initial  on  7th day was  significantly  higher  than  that  healthy  rats  (p  <  0.01).  The  value  in  the  insulin-treated  diabetic  rats  was  significantly  lower  than  that  of  the  untreated diabetic rats (p < 0.001) and the karela-treated diabetic rats (p < 0.001). There was no  significant  difference  between  the  values  of  the  untreated  diabetic  rats  and  the  karela-treated  diabetic  rats  (p  >  0.05).  Karela showed  a  tendency  of  acting  against hyperglycemic  effects  of  streptozotocin  induced  diabetes  mellitus  and  also  acting  against  high  serum  aspartate  aminotransferase  (AST)  level  in  streptozotocin  induced  diabetes  mellitus.  However,  further  investigations  are  recommended  for  establishing  karela  as  a  safe  and  useful  effective  anti-hyperglycemic  agent  as  well  as  an  agent  acting  against  the  rise  in  serum  AST  level  in  streptozotocin induced diabetic rats.Mediscope Vol. 2, No. 1: 2015, Pages 18-21

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

Background and Aim: Diabetes is a well-known disease with such complications, as retinopathy, nephropathy, and gastropathy. This study aimed to investigate the effects of thiamine and lead acetate on the colon of induced-alloxan diabetic rats; the effects of which become obvious in the treatment or reduction of tissue complications caused by diabetes. Methods & Materials: In this study, 63 rats weighing 200 g were divided into 9 groups, as follows: 1) Group of diabetes+pb acetate 200 ppm; 2) Group of thiamin+pb acetate 200 ppm; 3) Group of thiamine+pb acetate 1000 ppm; 4) Group of diabetes+thiamine+Pb acetate 1000 ppm; 5) Diabetes group; 6) Group of diabetes+thiamine; 7) Group of diabetes+thiamine+acetate 200 ppm; 8) Group of diabetes+pb acetate 1000 ppm, and 9) the control group. After 20 days, the study samples were removed from the abdominal cavity and the slides were prepared by routine tissue method. Then, the slides were evaluated for stereological and histomorphometric studies. Ethical Considerations: This study was approved by the Faculty of Veterinary Medicine, Shahrekord University (Code: GRN1M1903). Moreover, all methods used in the present study, including facilitation, were conducted per the ethical principles of animal restraint. Results: The mean thickness of mucosa-sub-mucosa suggested significant differences in groups 6 and 7, compared to other treatment groups. There was a significant difference in the thickness of the muscle layer between the control and all treatment groups except for groups 2, 6, and 7. There was no significant difference in the mean thickness of advantia layer in groups 1, 7, and 8, and the control group. The obtained results also indicated a significant difference concerning different layers of colon tissue between group 1 and controls. Conclusion: Based on the present research results, thiamine presented enhancing effects on muscle layer thickness and adventitia layer thickness. Furthermore, the area of the mucosal layer was not affected by the improving effects of thiamine.

Heat polymerized acrylic resin is the most common material used for making denture base because of it’s advantages. However, this material still hasn’t fulfill all the ideal requirements as a denture base. Some disadvantages that need to be fixed are low impact and transverse strength causing an easy base of fracture. Several attempts were made to improve the mechanical properties of heat polymerized acrylic resin materials by adding reinforcing materials. Zirconium oxide is one of chemical group that can be used as a reinforcing material and polypropylene fiber which is including in fiber reinforcing groups. This study aims to determine whether there is a difference in the effect of the addition of 5% ZrO2 nanoparticles and 2% chopped polypropylene fibers 6 mm in length on the impact and transverse strength of heat polymerized acrylic resin denture base material. The design of this study is a laboratory experimental and the number of samples in this study are 60 samples. The result of this study shows the mean value of the impact and transverse strength of heat polymerized acrylic resin with ZrO2 nanoparticles reinforced is greater than the control group and heat polymerized acrylic resin group with polypropylene fiber reinforced with significant difference, and the mean value of impact and transverse strength of heat polymerized acrylic resin with polypropylene fibers reinforced is greater than the control group with significant difference.

The aim of the present study is to examine experimentally the influence of using lexical chunks on the achievement of second-year-university students of English in the writing fluency. Lexical chunks, as the composites of form, meaning and function, stored and retrieved as a whole in brain, can release the language processing burden and improve the fluency and idiomaticity of language output. To accomplish this aim, the current study attempts to provide a reply for the following question: does drawing students’ attention to the lexical chunks frequently used in different positions help in better success in EFL descriptive essay writing lessons as contrasting to the presently applied method of teaching? Also two null hypotheses are planned. The first states that there will not be a statistically significant difference between the mean scores of the experimental group and those of the control group in the writing performance pretest. While the second one is that there will not be a statistically significant difference between the mean scores of the experimental group and those of the control group in the descriptive essay writing achievement posttest. The two groups pre-test post-test experimental design was adopted. After four weeks of instruction, the findings show that there is a significant difference between the experimental group and the control group in the post-test on the side of the experimental group. Accordingly, the main findings authenticated the first hypothesis of the study, but cancelled the second one. The control group gets the mean score 71.89 while the experimental group gets 76.53. This certainly implies that the use of lexical chunks as a language learning strategy gets better in students’ performance in writing fluency.

Objective: The postpartum period is a critical stage that exposes the mother to unpleasant experiences, including changes in energy level. Implementing reflexology during this period, as a branch of complementary medicine, may be helpful in promoting healthcare, especially in the areas of maternal and child health. Methods: In total, 70 eligible women who referred to health centers in the south of Tehran City, Iran, affiliated to Tehran University of Medical Sciences participated in this quasi-experimental study. A written informed consent form was obtained from them before initiating the study. The mothers of the postpartum routine care control group and the reflexology group received a massage for 3 consecutive days for 30 minutes (15 minutes per leg). Both study groups completed energy-related items in the Visual Fatigue Questionnaire before as well as immediately and one week after the completion of the intervention. The collected data were analyzed by SPSS. Results: Demographic characteristics and the energy level before intervention were homogenous in both research groups. Immediately after the intervention, the Mean±SD energy scores in the control and reflexology groups were 34.55±2.84 and 33.7±4.33, respectively; thus the obtained data revealed no statistically significant difference between the study groups (P=0.02). One week after the intervention, the Mean±SD energy scores in the reflexology and control groups were 35.87±2.71 and 35.5±3.43), respectively; thus, there was no significant difference between the study groups in this regard (P=0.64). Conclusion: The presented massage intervention was not as effective as a non-invasive low-cost method on the postpartum energy level of the study participants.

Background:Rheumatic diseases such as rheumatoid arthritis (RA) and spondyloarthritis (SA) may occur among women of childbearing age. Adverse events during pregnancy including disease flare, preterm delivery, and neonatal or fetal death have been reported.Objectives:Our aim was to assess the impact of rheumatic diseases on the course of pregnancy.Methods:We conducted a cross-sectional study involving patients with RA (2010 ACR/EULAR criteria) and SA (2009 ASAS criteria) (study group) as well as healthy controls (control group) matched by age and gender. All women included had at least one pregnancy. Data were collected through telephonic interviews. We used the Student t test to compare the study group and the control group.Results:We enrolled 57 patients (30 RA and 27 SA) and 57 controls. The mean age in the study and the control groups were respectively 43.2 ± 8.2 years [26-48] and 37.5 ± 6 years. The mean chronic inflammatory rheumatisms duration was 13.81 ± 6.2 years. A history of primary sterility was found in 3 patients (1 RA and 2 SA) and none in the control group. The mean age during the first pregnancy was significantly higher in the study group (28 ± 6.2 years versus 24 ± 7 years in the control group) (p=0.01). Eight patients (5 RA and 3 SA) had a history of spontaneous miscarriage. A terminated pregnancy was noted in 3 patients (1 RA and 2 SA). Complications during pregnancy in the study group were gestational diabetes (0.3%), premature delivery (0.3), premature rupture of membranes (0.3%), abortion threat (0.3%) and pre-eclampsia (6%). Pregnancy was more associated with complications in the study group (p=0.05). Cesarean section was more used in the study group (28 patients versus 9 in the control group; p= 0.00). The main indications of cesarean section in the study group were macrosomia (11 patients), scar uterus (6 patients), sacroiliitis (4 SA patients), twin pregnancy (2 patients), and undetermined reasons (6 patients). Fetal presentation in the study group was the seat presentation (3%), top presentation (4%), face (2%), and forehead presentation (0.3%) with no significant difference with the control group. Complications of childbirth in the study group were hemorrhage of delivery (10.3%), cord widening (6.6%), perinatal asphyxia (4.9%), and dystocia (1.9%). However, no statistically significant differences were found between the two groups in the prevalence of complications of childbirth. During pregnancy, 5 patients were on salazopyrine, 2 on corticosteroids and, 1 on non-steroidal anti-inflammatories.Conclusion:Our study showed that pregnancies with rheumatic diseases were at increased risk of having maternal complications and adverse neonatal outcomes.Disclosure of Interests:None declared
