The scientific name of rice is Oryza sativa. It is one of the important staple human foods. There are more than 110,000 cultivated varieties of rice, most widely known and grown. Nutrient concentration may vary depending on production, environment, pre- and post-harvesting treatment, and processing. Cooked rice with high amylose content effectively controls metabolic disorders, serum blood glucose levels, and lipid profile and is also effective in weight loss.

This study aimed to determine the comparative effect of amylose concentration in brown and white rice on hepatocellular insufficiency in healthy rat models.

We divided 25 rats into 5 groups (G0, G1, G2, G3, and G4). There were 5 rats in each group. Group 0 was the control group on a normal diet. Group 1 was fed white rice flour, G2 was fed cooked white rice, G3 was fed brown rice flour, and G4 was fed cooked brown rice. Free access to food and water was secured. Weight changes, blood glucose, and lipid profiles were analyzed pre and post-treatment.

Rats on white rice feed showed weight gain, increased blood glucose, cholesterol, triglycerides, and low HDL levels. However, rats on brown rice feed showed less weight gain (P < 0.05), a lower increase in blood glucose (P < 0.05), high HDL, lower LDL cholesterol, and triglycerides. The pancreas and liver histopathology showed no major changes due to the short trial duration.

Rats fed white rice showed ineffective results disturbing biological parameters as compared to those rats which were fed brown rice. Due to low amylose content and the presence of antioxidants, flavonoids, and high fiber content, brown rice shows beneficial effects in controlling and maintaining relevant biological parameters.

This study was conducted at the Department of ear, nose, throat, head and neck surgery, Post Graduate Medical Institute Lady Reading Hospital Peshawar. The duration of the study was one year from June 17, 2009 to June 16, 2010. The sample size was 82 patients with solitary thyroid nodule, fulfilling the inclusion criteria. After taking detailed history, thorough examination, relevant investigation and informed consent fine needle aspiration cytology was performed in all cases by the same cytopathologist. Thyroid surgery was performed and specimens were examined by the same histopathologist. The statistical analysis was performed using the statistical program for social sciences (SPSS version 11). Our study included 82 cases consisting on 57 female and 25 male, with female: male ratio of 2.28: 1.The age of the patients was ranged from 16-65 years with mean age of 42.56 + S.D 11.60 years. Most of the patients presented in 3rd and 4th decade followed by the 5th and 2nd decade. The diagnostic yield of Fine Needle Aspiration Cytology (FNAC) in this study was accuracy 82.92%, sensitivity 88.09%, specificity 77.50% and positive predictive value was 80.43%. 126 patients entered the study among which 77 (61%) were female and 49 (39%) male. Mean age was obtained as 26.9 ± 7.7 yrs. Up to 79.4% of patients had complaints concerning the cosmetic outcomes, 39.7% with respiratory and 4.8% with olfactory problems. The reason to sue the physician had a significant relationship with the patients’ age and sex, and also with the surgeons’ experience. FNAC has key rule in diagnosis of solitary thyroid nodule because it is safe, minimally invasive and cost effective diagnostic tool.
