Abstract
2-Acetylaminofluorene (2-AAF) is a known hepatic carcinogen which leads to tumour formation in rodents. 18-β Glycyrrhetinic acid (18 β-GA) derived from liquorice plant has various pharmacological properties such as anti-ulcer, anti-inflammatory, antiviral, hepatoprotective and antioxidant. This study is designed to elucidate the chemopreventive properties of 18 β-GA against 2-AAF-induced liver toxicity in Wistar rats and evaluated its effect on inflammatory and tumour promotion marker and activities of different oxidative stress enzymes. Administration of 2-AAF at the dose of (50 mg/kg body weight (b.w.) intraperitoneally (i.p.)) for five consecutive days induces hepatic toxicity, inflammation, oxidative stress and hyperproliferation. Pretreatment with 18 β-GA at two different doses (45 and 75 mg kg−1 b.w.) significantly ameliorates 2-AAF-induced increased lipid peroxidation, alanine transaminase and aspartate transaminase, xanthine oxidase activities and activities of phase-II detoxifying enzymes along with the levels of glutathione content. Administration of 18 β-GA also significantly restored the expressions of proliferating cell nuclear antigen, cyclooxygenase 2, inducible nitric oxide synthase and nuclear factor κB. Furthermore, histological observations also support the preventive effects of 18 β-GA. Our findings suggest that pretreatment with 18 β-GA showed potential hepatoprotective effects via attenuation of oxidative stress, inflammation and hyperproliferation.

Abstract
We report a case of mycosis fungoides in a 27-year-old woman who presented with a lump in the forehead. The condition was confirmed with tissue diagnosis. Gallium scintigraphy accurately delineated the complete extent of the disease, and served as a reference for objective assessment of response of the disease to treatment.

Abstract
10684 Background: Sequential use of docetaxel after four cycles of AC chemotherapy delays the postoperative radiation and can compromise loco-regional control. This delay can be avoided by starting radiotherapy concurrent with the docetaxel. We evaluated the feasibility of concurrent docetaxel and radiation therapy to chest wall and peripheral lymphatics after four cycles of AC chemotherapy. The preliminary results were reported in ASCO 2005 (Abstract 858). Methods: Females between 18–50 years, T2-T3 lesions, four or more positive nodes and hormone receptor negative tumors were eligible. Patients were enrolled after MRM. Four cycles of AC at 60/600 mg/m2 were followed by four cycles of docetaxel at 75mg/m2 every 21-days. Concurrent radiation to chest wall and peripheral lymphatics was started with the third cycle of docetaxel. A dose of 50 Gy in 5 weeks or equivalent was delivered. Successful completion of treatment in 18 out of 20 or 25 out of 30 patients was chosen as an index of feasibility. CTC version 2.0 of NCI and RTOG/EORTC Late Radiation Morbidity Scoring Scheme was used. Results: All the 30 enrolled patients successfully completed the planned treatment. Radiation was completed within 6 months of surgery in 27(90%) of the patients. Febrile neutropenia was seen in 5(16.7%). Grade-3 neutropenia and diarrhea in 8(26.7%) and 6(20%) respectively. Grade-3 dermatitis in the radiated area was seen in 2(6.7%) and grade-2 in 5(16.7%). Late toxicity included grade-2 skin atrophy and telangiectasia in radiated area in 6(20%) each. At a median follow up of 20 months (range 9–25 months) two local recurrences and two systemic relapses have been seen. Conclusion: This treatment schedule is feasible and safe in patients with high-risk operable breast cancer. It allows delivery of post mastectomy radiation within 6 months of surgery in patients undergoing sequential AC-docetaxel chemotherapy. No significant financial relationships to disclose.

Abstract
OBJECTIVE To confirm alpha-1-AT deficiency status in duodenal ulcer using a combination of PCR and restricted enzyme digestion. METHODS Fifty patients with endoscopically proven duodenal ulcer and hundred controls with no signs of the disease were included. Alpha-1-AT phenotypes were confirmed by polymerase chain reaction followed by restriction enzyme digestion. RESULTS Alpha-1-AT concentration in duodenal ulcer patients showed a mean value of 2.12 +/- 0.11 g/l (range: 0.52-3.95 g/l, p < 0.05). In controls this was 2.47 +/- 0.08 g/l (range: 0.52-5.0 g/l). Among the controls 70% had the MM phenotype, 28% M1 M2 and 2% FM. In duodenal ulcer, MM predominates (70%), followed by M1 M2 (18%), SS (4%), SZ (4%), ZZ (2%) and MZ (2%). CONCLUSION Alpha-1 AT deficiency was found in 10% of duodenal ulcer patients. DNA analysis more accurately resolved the phenotypes as S and Z mutations.

Abstract
OBJECTIVE To determine serum level of the protease inhibitor, to identify phenotypes and determine their frequencies. STUDY DESIGN A prospective study. SETTING PMRC, Research Centre, JPMC and the Aga Khan University Hospital, Karachi. SUBJECTS Healthy adults without history of peptic ulcer disease and a normal endoscopy. METHODOLOGY Quantitative measurement of serum alpha 1 AT was carried out by radial immunodiffusion, phenotyping by iso-electric focusing and confirmation of phenotypes by immuno-fixation and DNA analysis technique. RESULTS Serum alpha 1 AT was low in 13.4% of the subjects. MM phenotype predominated followed by SZ, SS,MZ and ZZ. DNA diagnosis accurately resolved the phenotypes as S and Z. CONCLUSION Frequency of phenotype associated with total and intermediate deficiency is less in the population.

Abstract
AIMS To see exposure rate of hepatitis E (IgG) in 100 apparently healthy children and adults. SUBJECTS AND METHODS Sera from 100 healthy children aged 1 day to 10 years and 100 healthy adults aged 18-45 years were analysed for exposure to hepatitis E (IgG) using ELISA. RESULTS Two samples from children were excluded from the study due to improper storage leaving 98 samples for analysis. Of 98 sera from children 19.4% were positive for IgG indicating previous exposure to hepatitis E. The exposure rate increased with age and was 10% in children below 1 year of age, 14% at 2 years, 19% at 3 years and 28% at 10 years. In adults overall exposure was 16%. There was no predominance of either sex in both the groups and all individuals belonged to middle to lower socioeconomic strata. CONCLUSION An exposure of 19% in children and 16% in adults indicates high faecal contamination of drinking water and re-addressing of the issue of use of boiled water on individual level, supply of potable water on the government level and a need to produce a vaccine on international level.

Abstract
Serum pepsinogen, alpha 1-antitrypsin (alpha 1-AT) and blood groups were studied as genetic markers in 32 patients with endoscopically proven duodenal ulcer and 44 control subjects with no family history of ulcer disease. Serum pepsinogen was determined by the modified method of Edward et al, alpha 1-AT by single radial immunodiffusion (RID) and phenotyping was carried out by isoelectric focusing (IEF). Duodenal ulcer patients with hyper- pepsinogenemia (28%) and low serum alpha 1-AT (35%) had a dominant blood group O, lower mean age, an early onset of disease, a higher frequency of gastrointestinal (GI) bleeding and ulcer perforation. These parameters were found considerably different in patients with normal serum pepsinogen and alpha 1-AT. Phenotype analysis of alpha 1-AT revealed that four duodenal ulcer patients had partial deficiency of the protease inhibitor and none of the normal exhibited the deficiency pattern. The etiology of the disease appears to be genetic anomaly in 28% of patients while the rest (72%) had ulcers as a result of neuroendocrinological or environmental factors.

Abstract
Using isoelectric focusing (IEF) and radial immunodiffusion (RID) techniques, serum samples from 100 normal healthy adults and 21 patients with pulmonary emphysema were analysed to identify various alpha 1 antitrypsin phenotypes and the serum concentrations. Ten percent of the patients had low serum values. The normal or most common genetic form, MM, is the predominant phenotype in both controls and patients.
