Abstract
Alkaloids are important sources of drug that's why we have conducted our research to find out the biological activity of the alkaloids of a plant that is the Amlaki. Alkaloids were extracted from the methanolic extract of the fresh ripe fruits of Amlaki (Emblica officinalis) through solvent-solvent partitioning method with n-hexane and chloroform. The chloroform soluble fraction of the crude methanolic extract of the ripe fruits of Amlaki containing alkaloids was subjected to antimicrobial activity and brine shrimp lethality bioassay for observing cytotoxic activity. The chloroform soluble fraction of the methanolic extract exhibited significant antimicrobial activity against some Gram positive and Gram negative pathogenic bacteria and strong cytotoxicity having a LC50 of 10.257 +/- 0.770 microg mL(-1). It is concluded that the chloroform soluble fraction of the ripe fruits of Amlaki containing alkaloids are biologically active.

Abstract
External exposure to environmental gamma ray sources is an important component of exposure to the public. A survey was carried out to determine activity concentration levels and associated doses from (226)Ra, (232)Th, (40)K and (137)Cs by means of high-resolution gamma ray spectrometry in the Swat district, famous for tourism. The mean concentrations for (226)Ra, (232)Th and (40)K were found to be 50.4 +/- 0.7, 34.8 +/- 0.7 and 434.5 +/- 7.4 Bq kg(-1), respectively, in soil samples, which are slightly more than the world average values. However, (137)Cs was only found in the soil sample of Barikot with an activity concentration of 34 +/- 1.2 Bq kg(-1). Only (40)K was determined in vegetation samples with an average activity of 172.2 +/- 1.7 Bq kg(-1), whereas in water samples, all radionuclides were found below lower limits of detection. The radium equivalent activity in all soil samples is lower than the limit set in the Organisation for Economic Cooperation and Development report (370 Bq kg(-1)). The value of the external exposure dose has been determined from the content of these radionuclides in soil. The average terrestrial gamma air absorbed dose rate was observed to be 62.4 nGy h(-1), which yields an annual effective dose of 0.08 mSv. The average value of the annual effective dose lies close to the global range of outdoor radiation exposure given in United Nations Scientific Committee on the Effects of Atomic Radiation. However, the main component of the radiation dose to the population residing in the study area arises from cosmic ray due to high altitude.

Abstract
AIMS To assess metabolic risk factors, insulin-resistance and lifestyle in children aged 8-20 years of patients with type 2 diabetes and to compare these with children aged 8-20 years of non-diabetic subjects. METHODS Case-control study. Data were collected from 37children/adolescents of type 2 diabetes patients and 37 controls from parents without diabetes. Variables included physical activity, diet, socioeconomic class, family history, ethnic background, anthropometric measures, blood pressure and fasting glucose and insulin. RESULTS Groups were comparable for age and gender. Differences between cases and controls were found for BMI (22.6 vs. 19.1kg/m(2), p=0.004), waist circumference (70.1 vs. 62.1cm, p=0.014), systolic blood pressure (104.5+/-15.1 vs. 97.9+/-13.4mmHg, p=0.05), diastolic blood pressure (66.2+/-10.9 vs. 60.7+/-10.1mmHg, p=0.025). Vegetable intake (3% of cases having two and 19% one full serving a day vs., respectively, 14% and 32% amongst controls, p=0.01) was less favourable in cases, and physical activity tended to be (5h vs. 9h/week, p=0.065). CONCLUSIONS Children of type 2 diabetes patients have higher BMI and blood pressure than controls but also lead a less healthy lifestyle. This suggests that both genetic and lifestyle factors contribute to the increased risk of metabolic syndrome in children and early preventive measures towards changing lifestyle could help in prevention.

Abstract
INTRODUCTION Previous studies have indicated that most individuals reach peak cortisol levels in 60 minutes during the short Synacthen test (SST) done to exclude adrenal insufficiency. Therefore, measuring serum cortisol at only 60 minutes may suffice. This study was carried out to evaluate the significance of the 60-minute serum cortisol level in SST as a reliable and cost-effective screening test in comparison to the conventional SST. METHODS A cross-sectional study was conducted from January 2000 to September 2004, in which data was collected by reviewing medical records of all patients who underwent SST at the Aga Khan University Hospital, Karachi. A total of 236 patients suspected of having adrenal insufficiency were included. Values of serum cortisol at baseline, 30 and 60 minutes post-250 ug-injection Synacthen were recorded. The cortisol level was measured through fluorescence polarisation immunoassay. The cut-off value of 20 ug/dL was used to differentiate normal individuals from hypoadrenal individuals. RESULTS Out of 236 study participants, 93 (39 percent) were males and 143 (61 percent) were females. The mean age and standard deviation was 44.4 +/- 21 years. Cortisol concentration increased significantly from baseline to 30 minutes and 60 minutes after injecting Synacthen (p-value is less than 0.001 for each). The majority of the patients reached the cortisol peak of greater than 20 ug/dL (555 nmol/L) at 60 minutes. Normal responses were found in 148 patients (63.1 percent) at both 30 and 60 minutes, while 27 participants (12 percent) reached a peak greater than 20 ug/dL (555 nmol/L) at 60 minutes but were less than 20 ug/dL (555 nmol/L) at 30 minutes. In the deficient cases, SST showed abnormal responses in 60 cases (25 percent) at both 30 and 60 minutes. However, there was only one patient who reached a peak value of 21 ug/dL (589 nmol/L) at 30 minutes, which reduced to 17 ug/dL (485 nmol/L) at 60 minutes. CONCLUSION This study showed that a 60-minute cortisol value during SST was reliable enough in identifying normal subjects for excluding adrenal insufficiency, and was equally effective in identifying abnormal cases, as compared to values at both 30 and 60 minutes. It is therefore suggested that a single 60-minute post-Synacthen serum cortisol level may suffice, as compared to the conventional SST. This is also significant as a cost-effective measure, especially in third world countries where cost is a major issue for diagnosing and treating patients.

Abstract
Purified glucoamylase (GA) from Fusarium solani was chemically modified by cross-linking with aniline hydrochloride in the presence of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) for 1 [aniline-coupled glucoamylase-1 (ACG-1)], 7 (ACG-7), and 13 min (ACG-13). The aniline coupling of GA had a profound enhancing effect on temperature, pH optima, and pK (a)'s of active site residues. The specificity constants (K (cat)/K (m)) of native, ACG-1, ACG-7, and ACG-13 were 136, 244, 262, and 208 at 55 degrees C for starch, respectively. The enthalpy of activation (DeltaH*) and free energy of activation (DeltaG*) for soluble starch hydrolysis were lower for the chemically modified forms compared to native GA. Proteolysis of ACGs by alpha-chymotrypsin and subtilisin resulted in activation.

Abstract
A review was made of the records of all patients with pulmonary tuberculosis and diabetes mellitus admitted over a 5-year period to a teaching hospital in Karachi, Pakistan. Among 42358 patients, the total number with both tuberculosis and diabetes was 173. The prevalence of tuberculosis in diabetic patients was 10-times higher than in non-diabetic patients and prevalence increased with duration of diabetes. The lower lung field was most frequently involved, followed by the upper and middle. Bilateral involvement was seen in half and an associated pleural effusion in one-third of the patients. Cavitating lesions were seen in 32% of men and 15% of women.

Abstract
A poor response to the infusion of anti-haemophilic factor (AHF) concentrates used to control acute bleeding or prevent haemorrhage during surgery may have many causes, including the lack of functional activity of the infused protein concentrate. It is generally recommended to follow the manufacturers' instructions when administering the factor intravenously. For convenience, infusion sets with 23 gauge butterfly needles are packaged with the major brands of AHF concentrate. In hospitals, blunt connectors for i.v. infusion are becoming more prevalent to reduce the risk of needle stick injuries to both patients and hospital staff. The integrity of AHF infused using such devices has not been examined. We examined the possibility that passage of complex proteins such as AHF through such devices may result in alteration of the protein, rendering it inactive. The results presented here suggest that this is not the case; neither the structure nor the function of AHF protein products was adversely affected by the use of the needleless transfer device (NTD) or the needle types and sizes commonly used in clinical practice. Samples of factor VIII and factor IX AHF concentrate were passed through the B-D Blunt Plastic Cannula or 23, 27 and 30 gauge needles. No significant changes in electrophoretic mobility or coagulation activity were detected. Samples generally showed slightly increased coagulation activity when compared with the control in which the sample was passed directly out of the syringe with no device attached. These data indicate that the NTD and various needle gauges are acceptable for the infusion of AHF concentrate in a clinical setting. Furthermore, the use of small gauge needles has advantages that may improve adherence to rigorous factor replacement programmes.

Abstract
A 37 year old man was found collapsed at the roadside and taken to the emergency department. Communication was difficult, as the patient could not speak English. There was a wound in the left second intercostal space on the midclavicular line, which was bleeding and was bubbling air. A drain was inserted, bleeding controlled, and his wounds sutured. Chest x ray later confirmed satisfactory placement of the drain. The following day, swelling and discharge indicated oesophageal damage, which was later confirmed by gastrografin swallow. With conservative management in hospital for 2 weeks, he made a full recovery and was discharged.

Abstract
OBJECTIVE To asses the clinical presentation of patients with thyroid cancer, their preferred diagnostic work-up and preferred surgical procedure. METHODS A retrospective chart review of patients that underwent partial or total thyroidectomy for thyroid cancer at AKUH between 1989 and 2002. SPSS was used to analyze data. Pearson's chi square and likelihood ratios used to calculate tests of significance. RESULTS A total of 97 patients were included in this review. Solitary thyroid nodule was the initial presentation in three. Majority (58.7%) presented with "neck swelling" or enlarging goiter. One out of every 3 patients showed evidence of lymph node involvement and 20% had distant metastases. The aggressiveness of the disease did not correlate with age, sex or histological subtype. There was no correlation between the size of the tumor and presence of local or distant metastases. CONCLUSION Thyroid cancer is a more aggressive disease in Pakistan, with majority of patients presenting with multinodular goiters, and a significant number have lymph node metastases. A higher degree of vigilance and a lower threshold for fine needle aspiration (FNA) is needed while evaluating patients with thyroid goiter.

Abstract
AIMS The aim of this study was to describe the clinical characteristics and outcomes of diabetic ketoacidosis (DKA) in Pakistani adult population with Type 2 diabetes mellitus. METHODS We reviewed the medical records of all adult patients admitted with a diagnosis of DKA and Type 2 diabetes mellitus (DM) and followed their clinical course and outcome. Follow-up data were obtained by chart review or telephone contact where necessary. RESULTS Fifty-seven patients fulfilled criteria for inclusion in the study. Their mean age was 48 +/- 7 years. The mean body mass index was 25.5 +/- 6.2 kg/m2. Forty-nine had a prior history of Type 2 DM but DKA was the initial presentation in 14%. Nine were on no treatment, 40 were using oral hypoglycaemic agents and eight were on insulin. A history of prior DKA was noted in eight patients. Infections were the most common precipitating factor (63%). There were 12 deaths. Follow-up after a period ranging between 12 and 43 months revealed that 30/45 patients remained on OHA without recurrence of DKA. CONCLUSION This report highlights the need for the growing recognition of DKA occurring in adults with Type 2 DM in the South Asian population. Mortality rates are unacceptably high but the majority of survivors remain insulin independent.

Abstract
OBJECTIVE To assess the surgical outcome of hypophysectomy in acromegalic patients, differences in response to surgery in micro and macroadenoma and the development of associated hormonal deficiency after surgery. METHODS Retrospective analysis of charts of acromegalic patients who were operated upon at Aga Khan University Hospital, Karachi, was done. Information regarding presentation, laboratory data, radiological assessment, details of surgery and postoperative outcome was recorded. Surgical outcome was classified depending on the degree of disease control after surgery as biochemical cure, remission and treatment failure. RESULTS Out of 30 patients, eighteen (60%) were males and 12 (40%) females with mean age at the time of diagnosis 35.6+/-10.4 years. The mean duration of symptoms was 3.2+/-2.4 years. Twenty-five patients had macroadenoma and five had microadenoma. Preoperative mean GH level was 42.4 ng/ml with range of 2.5 to 534 ng/ml. Following surgery, 13 had biochemical cure, 4 were in remission and 13 failed to respond. The outcome in microadenoma was better than in macroadenoma i.e. 100% vs. 32%. Preoperatively four patients had panhypopituitarism with additional six patients (20%) developing hypopituitarism postoperatively. CONCLUSION Our study showed that acromegaly was seen at a much earlier age, outcome of surgery was comparable to other international studies and postoperative panhypopituitarism was seen in significant number of patients. The outcome in microadenoma was better than in macroadenoma but the number of patients seen with microadenoma was small.

Abstract
Purified extracelluar glucoamylase from Arachniotus sp. was used for kinetic and thermodynamic characterization. Thermal inactivation followed first order kinetics. The denaturation/activation energies of enzyme were 57 and 89 kJ mol(-1), respectively. Both enthalpy and entropy of activation for inactivation were lower than those for glucoamylases reported in literature. It is suggested that the enzyme is highly thermostable and is suitable for industrial applications.

Abstract
OBJECTIVE A phase I single centre, open label study of the pharmacokinetics and tolerability of a buccal testosterone tablet (COL 1621) was carried out. DESIGN Twelve testosterone-deficient males were treated with the buccal tablet twice daily for 7 consecutive days. Multiple blood samples were drawn for testosterone, dihydrotestosterone (DHT), bioavailable testosterone and sex hormone-binding globulin (SHBG). RESULTS After COL 1621, means+/-S.D. serum testosterone level increased to a peak concentration of 26.6+/-5.8 nmol/l (7.7+/-1.7 ng/ml) at 4.8+/-5.8 h and stayed in the eugonadal range. Steady state was achieved within the first 24 h and was maintained in the normal range. The bioavailable testosterone, DHT and free testosterone index followed a pattern very similar to that of testosterone. The mean serum testosterone to DHT ratio was within the normal male range throughout treatment. There was only one treatment-related adverse event (headache). Two-thirds of patients indicated that treatment with COL 1621 was acceptable and that the tablet was convenient to use. Six patients (50.0%) preferred COL 1621 to their previous testosterone replacement therapy, two patients gave preference to their previous treatment and three patients found both treatments to be equally acceptable. Data for one patient was not available. CONCLUSION We conclude that COL 1621 can efficiently elevate serum testosterone and DHT levels in hypogonadal men within the first day of application, achieve a steady state within 24 h and maintain serum testosterone in the normal range with a twice-daily treatment regimen. COL 1621 provides an effective alternative oral testosterone replacement therapy that gives physiological levels of testosterone and is well tolerated by the patients.

Abstract
OBJECTIVE To compare insulin lispro with regular human insulin with respect to blood glucose control and frequency of hypoglycaemia in patients with type 1 diabetes who wished to fast during the month of Ramadan. RESEARCH DESIGN AND METHODS Insulin lispro or regular human insulin was given together with NPH insulin, twice daily before the morning and evening meals, for two weeks each in an open-label, randomised, cross-over design, and 64 patients completed the protocol. Blood glucose was self-monitored at fasting morning and evening, and 1-h and 2-h after the post-sunset meal on three consecutive days at the end of each treatment period. RESULTS The 2-h blood glucose excursion after the post-sunset meal was significantly (p=0.026) lower with insulin lispro (2.50 +/- 0.46 mmol/l) than with regular human insulin (3.47 +/- 0.49 mmol/l). Daily insulin doses did not differ between treatments but compliance with recommended time of injection was better with insulin lispro. Hypoglycaemia incidence (insulin lispro, 15 (23.4%) patients; regular human insulin 31 (48.4%) patients; p=0.004) and frequency (insulin lispro, 0.70 +/- 0.19; regular human insulin 2.25 +/- 0.36 episodes/patient/30 days; p<0.001) were lower with insulin lispro. Five (22.7%) of the episodes during insulin lispro occurred during the nocturnal period compared with 27 (36.5%) of the episodes while on regular human insulin. CONCLUSIONS Glycaemic control, measured by postprandial glycemic excursions, was improved and hypoglycaemia was significantly reduced with insulin lispro compared with regular human insulin. Patients with type 1 diabetes who insist on fasting during Ramadan may be better managed with insulin lispro.

Abstract
OBJECTIVE The aim of this study was to determine the standard of knowledge among people with diabetes. METHOD Two hundred and thirty patients were randomly chosen from outpatient clinics and a 34-item multiple choice questionnaire administered to them. The questionnaire was structured to assess knowledge about the disease state, diagnostic tests, complications and management. RESULTS The average score of correct answers for the group was 40%. A significantly higher score correlated with younger age (16-30 years), educational status and regular follow-up with a diabetic clinic. There was no significant difference in the knowledge score between males and females or between those on oral hypoglycemic agents (OHA) and insulin. Fifty percent of the patients could correctly answers questions regarding food and nutrition and only 60% were aware of target blood glucose levels for optimal control. It was alarming to learn that 75% of those on insulin did not know that using U-40 or U-100 insulin does not change the dose required. CONCLUSION The study emphasizes the need for diabetes education at all levels, both for the patients as well as the health care providers to counter the pandemic of diabetes-related complications globally.

Abstract
BACKGROUND The human dead body specimens are plastinated for teaching purposes in medical institutions, using silicone. The silicone impregnated whole brain specimens and brain slices do not give satisfactory results. METHODS In the present study the brain specimens were plastinated with another polymer known as Polyester-Copolymer. The brain specimens were first preserved and then fixed with 5% formalin. The specimens were then dehydrated and degreased in a volatile solvent acetone. The specimens were placed in Polyester-Copolymer solution which penetrated the brain tissue both intracellulary and intercelluraly. The specimens were then cured by gas method. RESULTS The whole brain specimens and brain slices plastinated with Polyester-Copolymer were dry, odorless, handy and durable. It also gives a clear visual contrast between grey and white matter in brain slices whereas the brain specimens plastinated with silicone are flexible and sticky. There was no color contrast between grey and white matter. CONCLUSION The polyester impregnated brain specimens and slices are non-toxic and ideal for teaching purposes and examinations. They require minimal aftercare. The whole organ serial sections of plastinated brain specimens will help 3-dimensional study of the normal brain and will improve the assessment of brain pathology.
