Many T2D use CAO as a laxative. We did not find sufficient research to explain CAO's potential effect on the levels of HbA1c in T2D patients. This study will study this effect. Rats (n=80) were divided into eight groups (n=10). Five groups (n=50) were injected with streptozotocin intravenously to induce T2D. One group was given CAO with empagliflozin, and the second was assigned CAO only daily. The third was assigned CAO every two days, with empagliflozin, which was given daily. A fourth was assigned CAO alone daily. Also, the fifth was given empagliflozin alone. In the healthy groups, one group was given CAO, and the other was given empagliflozin. Also, the last healthy group was not assigned any drug. CAO's result on HbA1c in healthy rats was noted to decrease when delivered alone for eight weeks. HbA1c of the diabetic groups showed no significant difference (P-value<0.05) when comparing the rats given CAO with empagliflozin, and the rats were given CAO only. There was also no noticeable effect among the groups of rats given CAO daily and every two days. This study explains that CAO does not lead to a significant difference in HbA1c levels in diabetic rats, even it did for healthy rats, and if given alone, CAO could affect HbA1c levels if given over a long period. Also, CAO has a noticeable impact on experimental rats that co-administered Empagliflozin on HbA1c levels, and that Empagliflozin effect is not significantly affected if taken with CAO.

Research summary
تستهدف هذه الدراسة استكشاف تأثير زيت الخروع على مستويات سكر الدم التراكمي (HbA1c) في الجرذان المستحدث فيها داء السكري من النوع الثاني. تم تقسيم الجرذان إلى ثماني مجموعات، خمس منها تم حقنها بمادة الستربتوزوتوسين لتحفيز السكري. تم إعطاء بعض المجموعات زيت الخروع فقط، وأخرى زيت الخروع مع دواء إمباغليفلوزين، بينما تم إعطاء مجموعة أخرى إمباغليفلوزين فقط. أظهرت النتائج أن زيت الخروع يقلل من مستويات HbA1c في الجرذان السليمة عند تناوله بمفرده لمدة ثمانية أسابيع، بينما لم يظهر تأثير كبير في الجرذان المصابة بالسكري. كما أن تأثير إمباغليفلوزين لم يتأثر بشكل كبير عند تناوله مع زيت الخروع. تشير الدراسة إلى أن زيت الخروع يمكن أن يؤثر على مستويات HbA1c إذا تم تناوله لفترة طويلة، ولكن تأثيره يكون أقل وضوحاً في الجرذان المصابة بالسكري مقارنة بالسليمة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في فهم تأثير زيت الخروع على مستويات سكر الدم التراكمي، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم توضيح الآلية البيولوجية التي يمكن أن تفسر تأثير زيت الخروع على HbA1c بشكل كافٍ. ثانياً، الدراسة اقتصرت على الجرذان ولم تتطرق إلى تجارب سريرية على البشر، مما يجعل من الصعب تعميم النتائج. ثالثاً، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تم تضمين مجموعات إضافية لتقييم تأثير جرعات مختلفة من زيت الخروع. وأخيراً، لم يتم مناقشة الآثار الجانبية المحتملة لاستخدام زيت الخروع على المدى الطويل، وهو جانب مهم يجب مراعاته.

Type 2 Diabetes mellitus T2DM has been suggested to be the most common metabolic disorder associated with magnesium deficiency which has many adverse outcomes. The aim of this study was to evaluate plasma Mg in 126 T2DM patients recruited from Dia betes Centre in Lattakia, compare them to 70 healthy individuals, and assess the correlation between plasma Mg and HbA1c as a glycemic control biomarker. Magnesium was measured using xylidyl blue colorimetric method. HbA1c was measured using ion-exchange resin separation. The SPSS 19.0 software was used for statistical analysis. Mean plasma Mg concentrations of the diabetics was significantly lower than controls (P=0.0001). Plasma magnesium was negatively correlated with HbA1c (r=-0.5, P=0.0002). Plasma magnesium was below the normal reference range (1.9-2.5 mg/dL) in 47.6% of diabetics and 28.6% of controls. In conclusion, it is important to monitor Mg levels in both T2DM patients and non-diabetics and take procedures to correct hypomagnesaemia states.
This study aims to compare between two globally approved strategies to manage diabetes type II in Syria, by comparing their effectiveness in patients with diabetes type II who are treated in the national program of diabetes Clinics in Damascus and in vestigate their glucose control. The first strategy includes glibenclamide as a monotherapy and the second includes a combination of glibenclamide and metformin.
Blood glucose control reduces the microvascular and macrovascular complications in patients with diabetes mellitus type II. According to the American Diabetes Association, less than a half of those with diabetes achieve optimal control of blood gluc ose and target values of HbA1c. Life style modifications is one of the preferences of diabetes management because the potential relationship between diet and diabetic control. So nutrition therapy which given by dietitian and generally lifestyle modifications are considered mainly integrated to traditional medication for disease. The study included 104 patients with diabetes type II (HbA1c 8% ± 1.07, BMI 26.45 ± 2.69, fasting blood glucose 148.25 ± 33.76) given diabetes self-management education program and divided into two groups. The first group was treated with glibenclamide only and the second was treated with a combination of glibenclamide and metformin. After three months monitoring, 103 patients Completed the study. Therapeutic efficacy was evaluated considering HbA1c ≤ 6.5% as a target value. The necessary statistical study to analyze the data and evaluate the statistical significance of the results was made. The results indicate that the treatment supported with life style modifications was more effective than traditional therapy and patient education at blood glucose control in patients with diabetes mellitus type II and improve their health.
Background: Diabetes mellitus is a leading public health problem with increasing incidence and long term complications. These complications are mainly a consequence of macro-vascular and microvascular damages of the target organs. The incidence of several pulmonary abnormalities during the course of Diabetes Mellitus because the presence of an extensive microvascular circulation and abundant connective tissue in the lungs , raises the possibility that lung tissue may be a target organ in diabetic patients. Objectives: This research is designed to study the impact of DM and both the duration of the disease and the glycemic control on pulmonary function tests. Methodology: This is a cross-sectional study carried out on 75 patients with type II diabetes mellitus patients at Tishreen University Hospital in the period between October 2015 and October 2016 .We compared with a control group consisted of 75 non diabetic healthy persons . Measurement of HbA1C , fasting plasma glucose (FPG) , and spirometry were made to all subjects and the following pulmonary function parameters were recorded: Forced Expiratory Volume in the first second (FEV1), Forced Vital Capacity (FVC), and Forced Expiratory Volume percent (FEV1/ FVC%) . Results were analyzed by calculating Mean ± SD, using X2 test , Karl Pearson correlation and ANOVA test. Results: The mean FEV1, FVC, FEV1/FVC% values were low in diabetics (p value <0.05) compared to healthy non-diabetics (control group). Also, uncontrolled diabetics show a greater decrease in these values than controlled diabetics. There was a greater decrease in these values in patients with long period of disease . Conclusion: The findings of the present study suggest that, the lung is a target organ for damage in DM and diabetics show a decrease in PFTs with a restrictive pattern lesion compared with non-diabetics . And this deterioration is exaggerated in uncontrolled diabetics and with the long duration of DM .
This research has done in aiming for the effect of extract of Nerium oleander plant in the level of blood sugar and total glucose , triple alglesiredat and total cholesterol on created albino mouse which has got diabetes. The results showed the fol lowing: - A Significant increase in the concentration on bothglucose, triple alglesiredat and cholesterol through a serum in the blood of created albino mouse which has got diabetes, while the weight decreases comparing to the control. - The injection of Aqueous extract led oleander leaves plant with dose of 200 mg / kg of mouse weight for a period of ten days to a significant decrease of concentration on glucose ,the rate of total cholesterol and triple alglesiredat, in addition to, the weight has returned to what it was before the injection.
