Paracetamol is the widely used non-steroidal anti-inflammatory drugs for the treatment of mild to moderate pain. It causes hepatotoxicity in therapeutic dose for prolonged time. It can induce centrilobular hepatic necrosis in large over doses. Nigella sativa (kalajira) is a medicinal plant has a protective role against hepatotoxicity. Therefore, the present study was designed to observe the protective role of Nigella sativa on paracetamol induced liver damage biochemically in Long Evans rats. The experiment was carried out in the Department of Anatomy, Dhaka Medical college, in the period of July 2003 to June 2004. Sixty matured Long Evans rats of either sex, age of 10-12 weeks and weighing between 150-200 gm were used in this study. They were divided into four equal groups. Group A was vehicle (distilled water) control group, Group B was Nigella oil treated group, Group C was paracetamol treated group and Group D was Paracetamol & Nigella sativa oil treated group. Paracetamol in a single dose of 3gm/kg body weight orally causes hepatotoxicity which was assessed bio-chemically. Nigella sativa oil at a dose of 800mg/kg body weight was administered orally for 4 weeks. It was found that significant elevation of serum alanine aminotransferase, serum aspartate aminotransferase, serum alkaline phosphatase and serum bilirubin level in paracetamol treated group. It was observed that 4 weeks oral treatment of Nigella sativa oil in Group D, decrease the level of serum alanine aminotransferase, serum aspartate aminotransferase, serum alkaline phosphatase and serum bilirubin. The result revealed that Nigella sativa oil able to give protection against paracetamol induced liver damage. However, more sophisticated biochemical studies like glutathione content and malondialdehyde level should be studied further.

The anticipated level of aganglionosis can influence the surgical planning in Hirschsprung's disease (HD). The aim of this study was to find out the role of barium enema in diagnosis of HD. Barium enema is usually performed in patients referred for investigation for constipation. This prospective study was performed in the department of pediatric surgery Chittagong Medical College & Hospital. During this period a total of 198 patients were clinically diagnosed as HD. All patients were initially evaluated by plain x- ray abdomen in erect posture. Among 198 patients, 43 patients had perforation in plain x- ray and 31 were clinically unstable at presentation. Those 74 patients were excluded from the study. Rest 124 participating patients were divided into three groups: Neonate, Infant and children according to their age. Male to female ratio was 2.44: I. Barium enema X- ray early film, 24 hours delayed film (Antero-posterior and lateral view) were done for every patient. Length of radiological narrow zone (RNZ), radiological Transitional zone (RTZ) and Recto-sigmoid index (RSI) was measured in cm. Photo of X- ray was taken for every patient. RIZ was demonstrated in 74 (60%) patients. RNZ was demonstrated in 94 (75%) studied population. RSI was measured in 65 (52.42%) subjects. Retention of barium more than 24 hours was found in 95 (75%) patients. Redundant sigmoid colon was found in 54 (43.5%) patients. Right-sided sigmoid colon was present in 46(30.6%) patients. Saw-toothed appearance in spastic colon was seen in 38 (30.6%) patients. Mucosal edema and irregularities were present in 25 (20.2%) patients. Rounded transverse colon was seen in 6 children. Barium mixed with stool was found in 32 (25.8%) patients. Mosaic pattern of colon was present in 10 patients. Visualization of RTZ is a reliable sign ofH13. Besides the RIZ BE in HD has various other radiological features.

Objective: The purpose of study was to compare Swenson & Soave-Boley procedure in the staged operative treatment of Hirschsprung's Disease (HD). Methods : During 16 months of study period, 25 patients of histopathologically confirmed HD were selected for staged operative treatment, following certain inclusion & exclusion criteria & were admitted & operated at DSH; after completion of all stages operation they were followed up & studied under two groups : staged Swenson procedure (Group-A; na=13) & staged Soave-Boley procedure (Group-B, nb=12). They were similar for age, sex, body weight, reselected length of aganglionic segment & postoperative follow up. The level of ganglionosis was assessed from marking biopsy. Preoperative & postoperative observations of Swenson procedure were analyzed & compared with those of Soave-Boley procedure in the staged operative treatment of HD statistically (unpaired ‘t' test & χ2 test) Results : For group A (Swenson procedure) the operative time was significantly lesser (unpaired ‘t' test : P < 0.01) than for the group B (Soave-Boley procedure). First bowel movement after colostomy closure was also significantly lesser in duration in Swenson procedure (χ2  test :P < 0.05). DOI = 10.3329/jom.v9i1.1420 J MEDICINE 2008; 9 : 16-19 Â
