Detection of Residual Levels and Associated Health Risk of Seven Pesticides in Fresh Eggplant and Tomato Samples from Narayanganj District, Bangladesh

Residual levels of seven frequently used pesticides were investigated in 140 samples of two common vegetables, eggplants and tomatoes, from agricultural fields in the Narayanganj district of Bangladesh. The analysis of pesticide residues was performed by high-performance liquid chromatography with photodiode array detection. A large percentage of the eggplants (50%) and tomatoes (60%) from the Narayanganj district were contaminated with pesticides, and all of the levels were above the maximum residual limit (MRL) proposed by the EC regulation. Diazinon was the most common (35%) pesticide detected in the vegetable samples at a concentration of 45–450 times higher than the MRL. The health risk index for diazinon was highest for both eggplant and tomato samples, which may be due to its physiochemical properties. Fenitrothion and linuron are the two second most common types of pesticides detected in the vegetable samples. Regular monitoring of the use of common pesticides on vegetables should be conducted.

Ganoderma lucidum and Auricularia polytricha Mushrooms Protect against Carbofuran-Induced Toxicity in Rats

The current study aimed to investigate the ameliorative effects of two types of mushrooms, Ganoderma lucidum (GL) and Auricularia polytricha (AP), against carbofuran- (CF) induced toxicity in rats. Male Wistar rats (n = 42) were divided into six equal groups. The rats in the negative control group received oral administration of CF at 1 mg/kg with the normal diet for 28 days. The treatment groups received oral administration of ethanolic extract of GL or AP at 100 mg/kg followed by coadministration of CF at 1 mg/kg with the normal diet for the same experimental period, respectively. In the CF alone treated group, there were significant decreases in the erythrocytic and thrombocytic indices but increases in the concentrations of the total leukocytes, including the agranulocytes. A significant increase in all of the liver function biomarkers except albumin, in lipid profiles except high-density lipoprotein, and in the kidney function markers occurred in the negative control group compared to the rats of the normal control and positive control groups. The coadministration of mushroom extracts significantly ameliorated the toxic effects of the CF. The GL mushroom extract was more efficacious than that of the AP mushroom, possibly due to the presence of high levels of phenolic compounds and other antioxidants in the GL mushroom.

Osteoma Left Mastoid Bone: A Case Report

Osteoid ostemoa is benign bone tumor and third most common benign neoplasm of bone. Young male are frequently affected three times more than females. It can occur in any bone but most common in long bone such as femer and tibia. In routine ENT practice osteoma are infrequently found in temporal bones most commonly seen in external ear canal. Osteoid ostemoa in mastoid are rare. We present such a rare presentation of ostema arising form the left mastoid in a young female.

Assessment of morbidity and mortality of thyroid surgery

Background: To find out the incidence and types of complications after thyroidectomy.To analyze the factors related to the complications of thyroid surgery. Material and method: The study was carried out at Shahid Suhrawardy medical college and Hospital, Dhaka from July 2007 to June 2008. Fifty patients were selected for the study who were treated by thyroidectomy. The mean patients age at the time of surgery was 41.9±8.1 years ranged from 10 to 60 years. Data were collected in a prescribed data collection sheet. Then all data were compiled and analyzed. Result: 12% of the patients had transient hypoparathyroidism, 4% had haemorrhage, 2% had permanent hypoparathyroidism, 4% had temporary recurrent laryngeal nerve (RLN) palsy and 2% had permanent recurrent laryngeal nerve palsy. Other rare complications were superior laryngeal nerve palsy, hematoma, and wound infection. Conclusion: Improved surgical techniques and proper management of complications reduce the postoperative morbidity and mortality of thyroid surgery. In spite of all measures, keen observation in postoperative period is very important to find out the complications for early intervention.
