TAFI antigen level variability in young healthy Asian Indians; first report from Asia

Thrombin Activatable Fibrinolytic Inhibitor (TAFI) is a plasma protein, which inhibits fibrinolysis by removing carboxyterminal lysine residues from partially degraded fibrin thereby decreasing plasminogen binding on its surface. In this study we have investigated the antigenic level variability (Inter and Intraindividual) of Thrombin Activatable Fibrinolysis Inhibitor in 120 healthy Asian Indians since no data on this is available regarding this population. TAFI antigen levels did not show a normal distribution in our population (p<0.001). Median TAFI antigen levels were found to be 11.683 microg/ml. It ranged from 33.9-202.5%of normal pool plasma (3.9-23.5 microg/ml). TAFI antigenic level showed high level of variability in the Indian population (coefficient of variation: 37.4%). TAFI antigenic levels were stable intraindividually (p=0.218).     

Alcohol consumption is associated with an increased risk of distal colon and rectal cancer in Japanese men: the Miyagi Cohort Study

The association between alcohol consumption and the risk of cancer of the proximal or distal colon or rectum remains controversial. We examined this association in a large population-based cohort of Japanese men. In 1990, a self-administered questionnaire on alcohol drinking and other health habits was delivered to 25,279 Japanese men aged 40 to 64 years of age. After exclusion of subjects who gave incomplete responses on alcohol drinking or prevalent cancer cases at the baseline, a total of 21,199 men remained. Of these, 307 men were diagnosed as having colorectal cancer after 11 years of follow-up. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), with adjustments made for potential confounders. Compared with never drinkers, past and current drinkers had multivariate HRs of 1.1 (95% CI, 0.6-1.9) and 1.6 (95% CI, 1.1-2.2) for colorectal cancer, respectively. A dose-response relationship with current volume of alcohol drinkers was observed for cancer of the distal colon and rectum, but not for proximal colon. The multivariate HRs for distal colon and rectal cancer among current heavy drinkers (45.6 g or more ethanol per day) as compared with never drinkers were 4.2 (1.6-10.7; p for trend=0.0002) and 1.8 (1.1-3.2; p for trend=0.04), respectively. In contrast, no significant linear association was found for proximal colon cancer (p for trend=0.2). These data indicate that alcohol consumption in Japanese men is associated with a statistically significant increased risk of cancer of the distal colon and rectum, but not cancer of the proximal colon.     

Alteration of serum copper in Kala-azar patients during SAG therapy

We conducted an analytic case-control study in Kala-azar patients during Sodium Antimony Gluconate (SAG) therapy to assess the changes in serum copper. A total of 89 subjects were included in the study. Diagnosed patients of Kala-azar with parasitological evidence of Leishmania Donovani (LD) bodies in bone marrow, were selected as cases (n=54). They were selected from Medicine and Paediatric wards of Mymensingh Medical College Hospital, Mymensingh and nearby Fulbaria upazila of Mymensingh district. Physically healthy volunteers of similar age, sex and body mass index (BMI) as cases, were included in control group (n=35). The study period was from July 2003 to June 2004. SAG was given intramuscularly (20 mg/kg/day) to Kala-azar patients for 30 days. Blood samples were collected from controls, Kala-azar cases before therapy and same cases during 15-20 days of SAG therapy. Serum copper was higher in cases before therapy than those of controls (p<0.001). However, serum copper reduced significantly (p<0.001) during SAG therapy. So biochemical monitoring may be considered in the management of the disease.     

Soluble dietary fibre fraction of Trigonella foenum-graecum (fenugreek) seed improves glucose homeostasis in animal models of type 1 and type 2 diabetes by delaying carbohydrate digestion and absorption, and enhancing insulin action

Trigonella foenum-graecum (fenugreek) seeds have been documented as a traditional plant treatment for diabetes. In the present study, the antidiabetic properties of a soluble dietary fibre (SDF) fraction of T. foenum-graecum were evaluated. Administration of SDF fraction (0 x 5 g/kg body weight) to normal, type 1 or type 2 diabetic rats significantly improved oral glucose tolerance. Total remaining unabsorbed sucrose in the gastrointestinal tract of non-diabetic and type 2 diabetic rats, following oral sucrose loading (2 x 5 g/kg body weight) was significantly increased by T. foenum-graecum (0 x 5 g/kg body weight). The SDF fraction suppressed the elevation of blood glucose after oral sucrose ingestion in both non-diabetic and type 2 diabetic rats. Intestinal disaccharidase activity and glucose absorption were decreased and gastrointestinal motility increased by the SDF fraction. Daily oral administration of SDF to type 2 diabetic rats for 28 d decreased serum glucose, increased liver glycogen content and enhanced total antioxidant status. Serum insulin and insulin secretion were not affected by the SDF fraction. Glucose transport in 3T3-L1 adipocytes and insulin action were increased by T. foenum-graecum. The present findings indicate that the SDF fraction of T. foenum-graecum seeds exerts antidiabetic effects mediated through inhibition of carbohydrate digestion and absorption, and enhancement of peripheral insulin action.

Human papillomavirus in tonsillectomy specimen from China and Pakistan — Prevalence and genotype distribution

Background

The expected corresponding increase in tonsillar human papillomavirus (HPV) infection associated with increasing incidence of oropharyngeal squamous cell carcinoma (OPSCC) substantiate the evaluation of normal tonsillar tissue in different population. The epidemiology of HPV in tonsillar tissue varies geographically. This study evaluated samples from two countries to determine the prevalence in respective samples.
