ABSTRACT
Objective To investigate the effects of different doses of artemether on glycolipid metabolism in C57BL/KsJ-db/db mice. Methods Eight-week-old male C57BL/KsJ-db/db mice were divided into model group (ig given 1% methylcellulose) and artemether 400, 200, 100, 50 groups (ig given 400, 200, 100, 50 mg/kg artemether respectively + 1% methylcellulose), with six mice in each group. Another six male C57BL/KsJ-db/+ mice were selected as the control group. All groups were administered for 4 weeks. The quality of the mice was measured every 2 d; The food intake of the mice was measured every 3 d and the average daily food intake and body mass changes were evaluated; The amount of water in mice was measured every 2 d; The urine volume of the mice was measured every 3 d; After 8 h of fasting, blood was collected from the tail vein, and the fasting blood glucose of the mice was measured by Roche blood glucose meter and matching test paper every 7 d. Mice were assessed for glucose tolerance and sensitivity to insulin by ip glucose tolerance test (IPGTT) and ip insulin tolerance test (IPITT). The serum total cholesterol (TC), triglyceride (TG), and free fatty acid (FFA) levels of the mice were determined by a biochemical kit. The whole liver of mice was weighed and the morphological changes of the pancreas and liver in mice were observed by HE staining. The expression of AMP-activated protein kinase (AMPK), glucose transporter 4 (GLUT-4), and insulin receptor β (IRβ) protein in liver of mice was analyzed by Western blotting. Results Compared with the control group, the food intake, water intake, and urine volume of the model group were significantly increased (P < 0.001). Compared with the model group, each dose of artemether significantly reduced the water intake and urine volume of the mice (P < 0.01, 0.001); Artemether 400, 200, 100 mg/kg can significantly reduce the body weight and food intake in a dose-dependent manner (P < 0.05, 0.01); Artemether 400, 200, 100 mg/kg significantly reduced fasting blood glucose levels in mice, reduced the area under the curve of IPGTT (AUCs), and improved insulin resistance in mice (P < 0.01, 0.001). Compared with the control group, the TC, TG, and FFA levels of mice in the model group were significantly increased (P < 0.05). Compared with the model group, artemether significantly decreased the levels of TC, TG, and FFA in the serum of mice in a dose-dependent manner (P < 0.05), and significantly improved islet vacuolar degeneration and hepatic steatosis in db/db mice; The protein expression of AMPK, GLUT-4, and IRβ in the liver of mice was increased (P < 0.05). With the prolongation of the intervention time, the higher the dose of artemether, the higher the mortality rate and the incidence of adverse reactions in mice. Conclusion Artemether can significantly improve the high-fat state and insulin resistance of diabetic mice. It can treat fatty liver and may up-regulate the expression of GLUT-4 and IRβ protein through the AMPK pathway to exert its effects. It is expected to be used in the treatment of type 2 diabetes mellitus, which is mainly caused by metabolic syndrome. However, higher doses of artemether and longer-term application may lead to more adverse events.
ABSTRACT
Background: It is of high value to be assess the relationship between doses of Acenocoumarol and the INR values to offer better patient care. Since Acenocoumarol is a commonly used drug with a narrow therapeutic range it is essential to monitor the variations encountered in response to it to avoid drastic complications and to provide better health care. Aim: The aim of this study is to compare the INR values with different doses of Acenocoumarol, to compare the association of dose of Acenocoumarol with their respective INR and to find out the occurrence of bleeding with different doses of Acenocoumarol.Methods: The study was conducted in a Tertiary care hospital. 40 patients taking Acenocoumarol were recruited in the study. Relevant details like age, weight, dose of Acenocoumarol, INR and other concomitant drugs were obtained in a prospective manner. Correlation of dose of Acenocoumarol with respective INR was done by simple linear regression.Results: The relationship between dose and INR was analyzed using Simple linear regression and the scatter plot revealed no significant correlation between the dose and INR values. There is a lot of inter-individual variability in the dose response and thereafter the INR values.Conclusions: The dose of Acenocoumarol cannot predict INR values. Patient can ideally be started treatment on a low dose of Acenocoumarol and based on the INR values, dose can be titrated. There is a need for consideration of other factors which influence the dose and INR values.

ABSTRACT
PURPOSE : Since the combination of cisplatin plus gemcitabine (CG) had a significant survival advantage for the treatment of patients with chemotherapynaive advanced or metastatic non-small cell lung cancer (NSCLC), CG combination have been evaluated with different schedules. However, the best schedule is still unclear. We designed to compare the efficacy and toxicity of CG combination chemotherapy in two different doses of gemcitabine (1,000 or 1,250 mg/m2 3-weekly). MATERIALS AND METHODS : We randomized patients with stage III or IV NSCLC into either gemcitabine 1,250 mg/m2 or gemcitabine 1,000 mg/m2. Patients received cisplatin 60 mg/m2 intravenously on day1 of each 3-week cycle. Gemcitabine was administered intravenously on days 1 and 8 of each 3-week cycle. RESULTS : From April 2002 until July 2004, 125 patients were enrolled from four university hospitals (55 patients in the gemcitabine 1,000 mg/m2 arm and 70 patients in the gemcitabine 1,250 mg/m2 arm). Response rates were not significantly different in both arms (56.4% vs. 55.7%). However, grade 3 neutropenia was significantly lower in gemcitabine 1,000 mg/m2 arm compared to gemcitabine 1,250 mg/m2 arm (11.0% vs. 15.8%). No differences in non-haematologic toxicities in both arms except anorexia were observed. The median survival was 13.4 months for gemcitabine 1,000 mg group compared with 15.8 months for gemcitabine 1,250 mg group. There were no statistically significant differences in survival between the groups. CONCLUSION : For stage III or IV non-small cell lung cancer, combination chemotherapy with gemcitabine 1,000 mg/m2 showed equivalent response rate with lesser neutropenia and anorexia compared to treatment with gemcitabine 1,250 mg/m2
