RESUMO
Background: Type 2 diabetes mellitus is becoming one of themajor health problems worldwide. Especially in South EastAsia, type 2 diabetes has gained critical significance. Asprediabetes prevalence is increasing worldwide, it has becomean important concern to prevent diabetes at an early stage inBangladesh.Objectives: Estimation of serum zinc level and establishmentof its relation with glycemic status in individuals with prediabetes.Materials and Methods: This cross-sectional studyencompassed 126 (age: 35.09±9.96 years, mean ± SD; Sex:16/110, M/F) subjects with prediabetes and 126(age:29.08±9.28 years, mean ± SD; Sex: 22/104, M/F) healthynondiabetic controls from the out-patient department ofEndocrinology, BSMMU consecutively. Serum zinc wasmeasured by using Atomic Absorption Spectrophotometry.Height, weight, waist circumference, acanthosis nigricans,hypertension, SGPT& serum creatinine were recorded asconfounding variables.Results: Serum zinc level in persons with prediabetes waslower than that in control (0.76±0.01 vs. 0.78±0.01mg/L,M±SEM, p=0.28). There was statistically significant differencefor zinc level in gender groups (M vs. F: 0.84±0.02 vs.0.75±0.01 mg/L, M±SEM, p<0.001) and monthly family incomegroups (p=0.02). Also zinc level was statistically similar amongglycemic status groups apart from zinc level in between controland combined glucose intolerance (CGI) groups (control vs.CGT: 0.78±0.01 vs. 0.72±0.02mg/L, M±SEM, p=0.03). Amongcases comparisons between groups with or without risk factorslike: smoking (0.72±0.03 vs. 0.76±0.10 mg/L, p=0.42),smokeless tobacco (0.73±0.03 vs. 0.76±0.01mg/L, p=0.46),hypertension (0.80±0.03 vs. 0.75±0.01 mg/L, p= 0.14), familyhistory of DM (0.75±0.02 vs. 0.77±0.02mg/L, p=0.52), familyhistory of CVD (0.74±0.02vs.0.77±0.01mg/L,p=0.28), overweight (0.76±0.01 vs.0.74±0.05mg/L, P=0.59), waistcircumference (0.75±0.01 vs. 0.79±0.04mg/L, p=0.40) andacanthosis nigricans (0.75±0.02 vs. 0.76±0.02mg/L, p=0.70),showed no statistically significant difference. None of thevariables like age (r= -0.02, p=0.19), BMI (r= 0.14, p=0.12),FPG (r= -0.05, p=0.60) and PG 2h after 75g glucose (r=0.10,p=0.28), HbA1c (r=0.04, p=0.64), serum creatinine (r=0.01,p=0.87) showed significant relationship with the level of zincexcept SGPT which showed significant relation with zincamong cases (r= 0.28, p=0.002) and among all participants(r=0.17, p=0.008) but not in control group (r=0.07, p=0.43).Conclusion: It is concluded that persons with prediabetes hadserum zinc level within normal limit and there was found nostatistically significant relationship between HbA1c and zinc
RESUMO
A 5-fluorouracil (5-FU) is used for cancer treatment despite its cytotoxic sequelae on healthy cells, especially the rapid proliferating ones. Intestinal mucositis is one of the most frequent chemotherapeutic debilitating sequelae. Rhubarb (Rh), an ancient herb, is known for its curing effect on gastrointestinal complications. This study aims to detect the role of aquaporin-4 (AQP-4), tumour necrosis factor-α (TNF-α), nuclear factor-kappa B (NF-κB), and matrix metalloproteinase-9 (MMP-9) in 5-FU-induced ileal histological and biochemical changes and the potential therapeutic effect of Rh water extract on these changes in rats. A 45 rats were divided into 3 groups; control, 5-FU (single intraperitoneal injection of 150 mg/kg/rat) and Rh-treated (oral 20 mg/kg/day/rat for 8 days). The change in animals’ weight, incidence of diarrhoea and AQP-4 and TNF-α values in ileal homogenates were measured. Ileal sections were subjected to hematoxylin and eosin stain, periodic acid Schiff (PAS)-reaction and MMP-9, NF-κB and AQP-4 immunohistochemical staining. A 5-FU group revealed marked ileal mucosal damage associated with a significant decrease in the mean body weight, AQP-4 level and area percent of PAS and AQP-4 positive reaction. Significant increase in the mean incidence of diarrhoea, TNF-α value and area percent of MMP-9 and NF-κB was detected. These changes were significantly corrected with Rh administration. A 5-FU resulted in severe ileal mucositis through TNF-α, NF-κB, MMP-9, and AQP-4 disturbances. Rh treatment was highly effective in preventing such mucositis.
RESUMO
Eight amalgam alloys representing various shapes of particle and copper percentage were used in this study. The products studied were In-diloy, Sybralloy, Jentalloy-III, Epoque, Cluster, Contour, Disper-salloy, and Cupralloy. The eight amalgam alloys placed in standardized class V cavities in freshly extracted non-carious molar teeth, were tested for marginal leakage to a radioisotope after thermal cycling. From the results of this study we can conclude that: 1- The marginal leakage around the different amalgams does not depend on the particle shape or distribution. 2 - Copper percentage would have no effect on the degree of leakage around the different restorations. 3 - After one year all amalgams tested showed a virtual reduction of microleakage
