Comparative effects of some medicinal plants on blood glucose concentration and lipid levels in alloxaninduced diabetic rats

The comparative effects of the chloroform extracts of the leaves of Psidium guajava (Myrtaceae), Anacardium occidentale (Anacardiaceae) and Eucalyptus globulus (Myrtaceae) and fruits of Xylopia aethiopica  (Annonaceae) on blood glucose concentration and lipid levels of diabetic rats were investigated using standard methods. The results show 74, 82 and 83% reductions in the blood glucose concentrations upon the  administration of A. occidentale (100 mg/kg body weight), E. globulus (100mg/kg body weight) and X. aethiopica (250 mg/kg body weight) extracts respectively as from the 10th hour of treatments in relation to the 74 and 69% reductions in glibenclamide and diabetic untreated groups respectively while the synergic treatment group [A. occidentale + E. globulus (100 mg/kg body weight)] showed 83% decrease in the blood glucose  concentration as from the 10th hour upon the administration of the combined extracts when compared with the values obtained for the glibenclamide and diabetic untreated groups. P. guajava extract had the greatest significant (p<0.05) reduction in the total cholesterol concentration of the treated rats. P. guajava + X. aethiopica treatment group in a similar manner showed the most significant (p<0.05) decrease in the triglyceride concentration of the treated rats. Hence, the individual  performances of these extracts on blood glucose concentration and blood lipids confirm their ability to reduce blood glucose and diabetic  complications.Key words: Chloroform extract, Psidium guajava (Myrtaceae), Anacardium occidentale (Anacardiaceae), Eucalyptus globulus (Myrtaceae), Xylopia aethiopica (Annonaceae)

Hypoglycaemic and Haematinic properties of ethanol leaf extract of Artocarpus heterophyllus in alloxan induced diabetic rats.

Background: Anaemia is known to be associated with diabetes; moreover, with the increasing cases of diabetes there is need for the use of more affordable alternative herbal medicines for the treatment of diabetes and anaemia. The aim of this work was to evaluate the hypoglycaemic and haematinic properties of Artocarpus heteropyllus on diabetic rats.Materials and Methods: Ethanol leaf extract of Artocarpus heteropyllus was screened for phytochemicals and its acute toxicity was tested on mice. Induction of diabetes was done at a dose of 150 mg/kg body weight (b.w) (with exception of the control group). The extract was administered to rats for a period of 7 days at 100, 300 and 500 mg/kg b.w, respectively, following induction. Blood samples of rats were tested for fasting blood sugar (FBS), packed cell volume (PCV), white blood cell (WBC), red blood cell (RBC), haemoglobin, neutrophil lymphocyte and eosinophil counts.Results: The ethanol leaf extract of A. heterophyllus showed no mortality up to a dose of 5000 mg/kg b.w. Administration of the extract to diabetic rats resulted in a decrease in the FBS of diabetic rat, and significant increases (p< 0.05) in RBC, PCV, WBC and haemoglobin levels.Conclusion: The ethanol leaf extract of A. heterophyllus increased the haematological indices of diabetic rats. Our findings support the use of this plant as an herbal alternative in the treatment of diabetes and anaemia associated diabetes.Key words: Diabetes, Hypoglycaemia, Haematology, Alloxan, Oxidative stress

Can Oral Zinc Supplementation Reduce Relapses in Childhood Steroid-Sensitive Nephrotic Syndrome? A Systematic Review

Acute respiratory infection (ARI) is the most frequently reported trigger of relapse. Given the role of zinc supplementation in preventing ARI, some studies show that this targeted intervention may reduce relapses in childhood SSNS.Aim: This systematic review aimed to determine if oral zinc supplementation can significantly reduce relapses in this disease.Methods: We searched the PubMed and Google Scholar electronic databases for interventional and observational analytical studies without limiting their year or language of publication. We selected studies with primary data that met our inclusion criteria, screened their titles and abstracts, and removed duplicates. We used a preconceived structured form to extract data items from selected studies and conducted a quality assessment of randomized controlled trials (RCTs) and non-randomized studies with the Cochrane collaboration tool and the Newcastle Ottawa Scale, respectively. We qualitatively synthesized the extracted data to validate the review’s objective.Results: Eight full-text articles were selected, comprising four RCTs and four observational analytical studies. Two of the RCTs had a high risk of bias in three parameters of the Cochrane collaboration tool, while three non-randomized studies had low methodological quality. A total of 621 pediatric patients with SSNS were investigated in the eight studies: six participants dropped out in one study. Three RCTs indicate that zinc supplementation may lead to sustained remission or reduction in relapse rate. Similarly, three observational analytical studies suggest a significant relationship between reduced serum zinc levels and disease severity.Conclusion: Despite the association of zinc deficiency with increased morbidity in SSNS and the reduction of relapse rates with zinc supplementation, there is no robust evidence to recommend its use as a therapeutic adjunct. We recommend more adequately-powered RCTs to strengthen the current evidence.Keywords: acute respiratory infection, frequent relapses, nephrotic syndrome, childhood, zinc supplementatio

Understanding Fertility in Young Female Cancer Patients

Young women diagnosed with cancer today have a greater chance of long-term survival than ever before. Successful survivorship for this group of patients includes maintaining a high quality of life after a cancer diagnosis and treatment; however, lifesaving treatments such as chemotherapy, radiation, and surgery can impact survivors by impairing reproductive and endocrine health. Studies demonstrate that future fertility is a concern for many women diagnosed with cancer, but physician knowledge and attitudinal barriers can still prevent females from receiving care. Today, fertility preservation is an option for girls and women facing a cancer diagnosis, and emerging research is providing clinicians with an increasing number of reproductive and hormonal management tools. Physicians can play an important role in fertility by working closely with oncologists, providing patients with information about fertility preservation options prior to the start of cancer treatment, monitoring reproductive capacity after treatment, and working with cancer survivors to explore potential avenues to parenthood.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140135/1/jwh.2015.5194.pd
