Abstract
This retrospective study in pediatric ward of general hospital, which is a secondary care level hospital having 100 beds. Study period was six months, from 1st July 2006 to 31st December 2006. Records of all admitted patients was meticulously reviewed and analyzed. During this period 11,580 patients were admitted in the hospital of which 2638(22.86%) were pediatric patients. Among the pediatric patient 909(34.46%) were neonate. These 909 neonates were enrolled in this study. The top three neonatal diseases were perinatal asphyxia (57.2%), neonatal septicemia (18.5%) low birth weight including very low birth weight (8.91%). Among admitted patient 70% were out born. Most of the neonatal disease were male predominant. Most of the death was due to perinatal asphyxia (63.06%) then septicemia (17.88%) and preterm low birth weight including very low birth weight babies (8.99%). Death among low birth weight babies were higher (35.58%) than normal birth weight babies (27.29%). Death also was common in preterm babies (43.70%) than term babies (16.8%). Association of septicemia and death among low birth weight babies were higher than normal birth weight babies. Association of septicemia among low birth weight babies was 33.06% and among normal birth weight babies were 12.87%. Death among low birth weight babies was 23.1% and among normal birth weight babies were 16.87%. Total death rate among admitted patients was 20.79%.

Abstract
OBJECTIVES We studied the role of the regulatory T cells CD4+CD25+ (Treg) and activated CD4+CD30+ cells in the pathogenesis of asthma and their association with apoptosis and NF-kappaB in patients with mild intermittent asthma (MA), severe persistent asthma (SA), and healthy volunteers (HV). METHODS Peripheral blood lymphocytes (PBL) were extracted from asthmatic patients during exacerbations, and CD4+ cells were separated using Dynal beads. Immunostaining of whole PBL for NF-kappaB, Bax, and Bcl-2, and immunostaining of CD4+ cells for CD25+ and CD30+ cells were performed using immunocytochemistry. RESULTS Treg cells were expressed at higher levels in MA than in HV and SA (P < .05), while CD30+ T cells were expressed at higher levels in both SA and MA than in HV (P < .05), although there was no remarkable difference between SA and MA (P>.05). Levels of NF-kappaB, Bcl-2, and Bcl-2/Bax increased, whereas those of Bax decreased, progressively, from MA to SA (P < .05). NF-kappaB levels correlated directly with the Bcl-2/Bax ratio and with CD4+CD30+ cells in SA and MA, whereas CD4+CD30+ cells correlated inversely with the Bcl-2/Bax ratio. CONCLUSIONS Unregulated Treg cells probably return inflammatory responses to normal values during exacerbations in MA; however, expression of Treg cells was extensively diminished in SA, leading to probable loss of suppressive control over underlying immune reactions. CD4+CD30+ cells were associated with the pathogenesis of asthma but not with severity. NF-kappaB seems to be the central inflammatory factor in SA, with a remarkable loss of PBL apoptosis, diminished Treg levels, and high CD30+ cell levels that probably induce NF-kappaB, which in turn blocks the proapoptotic potential of CD30 induction itself.

Abstract
This prospective cross sectional study was carried out in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka. This study was undertaken to compare the haematological value (reference range) among Small for gestational age-low birth weight (SGA-LBW), Appropriate for gestational age-low birth weight (AGA-LBW) and Normal birth weight (NBW) babies. Total 90 (ninety) newborn babies were enrolled in this study. They were ultimately divided into three groups as a) Group I (SGA-LBW), b) Group II (AGA-LBW), c) Group III (NBW). Study period was one year (December 2003 to December 2004), Relevant informations were collected from the guardian of the babies before inclusion in the study. In group I, 19(63.3%) were preterm and 11(36.7%) were term. In group II, 30(100%) were preterm and in group III, 30(100%) were term. Mean Hb, and HCT levels were highest in group I (SGA-LBW) and the value was 17.14+/-1.41 gm/dl (Hb) and 0.51+/-0.04 (HCT) respectively. Mean Hb and HCT value were lowest in group II (AGA-LBW) and the value was 14.57+/-1.78 gm/dl (Hb) and 0.43+/-0.05 (HCT) respectively. In between value was found in group III (NBW) and the value was 16.14+/-1.09 gm/dl (Hb) and 0.48+/-0.04 (HCT) respectively. Differences were statistically significant. On the contrary, MCV Values were highest in group II (AGA-LBW) and the value was 103.23+/-4.99 (fl). Lowest MCV value was in group III (NBW) and the value was 98.13+/-3.93 (fl). In between result of MCV value was found in group I (SGA-LBW) and the value was 99.27+/-10.73 (fl). Differences were also statistically significant. MCH and MCHC level was also highest in group I (SGA-LBW). Difference was also statistically significant. No significant differences of TC of WBC and platelet counts were not found among different groups. Hb and HCT level had significant positive correlation with gestational age. Other parameters had no Positive correlation with gestational age.

Abstract
Zschokkella helmii n. sp., a new parasite of Siganus rivulatus from the Red Sea, Egypt, was described using light and transmission electron microscopy. However, the infection was severe; single "histozoic" plasmodium was encountered in the gallbladder wall. Spores are ellipsoid with 9-11 valvar striations. Spore mean length is 10.8 microm (10.0-11.0), while the spore mean width is 7.5 microm (7.0-8.0). Polar capsules are nearly round with a diameter of 2.2 microm (2.0-3.0) and have five filaments. Ultrastructure of the plasmodial wall and sporogenesis of the present species followed the usual pattern valid for most studied myxosporean species.

Abstract
SETTING Damien Foundation tuberculosis (TB) control projects in Bangladesh. OBJECTIVE To assess the effectiveness of a 1-month extension of the intensive phase for smear-positives at 2 months of an 8-month regimen with a continuation phase consisting of isoniazid (INH) and thioacetazone (Th). DESIGN A prospective study of two cohorts of newly registered smear-positive cases, with extension of the intensive phase for the control cohort, but not for the study cohort. Culture and drug susceptibility testing (DST) of smear-defined failures and relapses and of random samples of new cases. RESULTS Among 8230 study patients (86.7% 2-month conversion) and 7206 controls (83.4% conversion), smear-defined failure or relapse outcome was 3.0% for 2-month smear-negatives vs. 3.1% for 2-month smear-positives with extension (non-significant, NS), and 8.2% for 2-month smear-positives with no extension (P < 0.00001). Culture-confirmed failure and relapse reached 1.9% in 2-month smear-negatives and 1.6% (NS) in 2-month smear-positives with vs. 3.7% (P < 0.001) in 2-month smear-positives with no extension. The relative risk (RR) of non-extension in 2-month smear-positives was 2.4 (cultures) to 2.7 (smears). The same RR and borderline significance was found for non-extension of patients with pan-susceptible strains. CONCLUSIONS Extension of the intensive phase considerably reduces failures and relapses with a weaker regimen in patients smear-positive at 2 months. Its effectiveness may vary with extent of initial drug resistance vs. power of the regimen.

Abstract
A new myxosporean parasite, Myxobolus lubati n. sp., was described from the wall of the intestine of haffara seabream Rhabdosargus haffara (Forsskal 1775), Red Sea, Egypt. Macroscopic plasmodia of about 300 mum diameter were located in the circular muscle layer of the intestine. The spores were ovoid and sometimes ellipsoid and measured 9.8 x 7.2 mum. The shell wall of the spore was thickened at the posterior end and marked with 5-7 sutural markings. Polar capsules were equal and pyriform with three polar filament turns situated in the posterior half of the polar capsule. Polar capsules measured 4.2 x 1.6 mum. Histological evaluation of the infection revealed a slight distention of the intestinal layer of muscularis. Ultrastructure of the plasmodial wall and sporogenesis of the present species followed the usual pattern valid for most studied myxosporean species.

Abstract
Measurement of QT dispersion as calculated from the 12-lead ECG has emerged as a non-invasive assessment for degree of myocardial inhomogeneity. Increased QT dispersion predicts sudden cardiac death in variety of disease states such as acute myocardial infarction and hypertrophic cardiomyopathy. To improve identification of athletes at high risk of sudden death, resting electrocardiograms were performed on 100 dynamic athletes (sprinters, middle and long distance runners), 50 static athletes (Hammer throwers, Weight lifters) and 100-matched control group. QT dispersion was defined as maximum QT interval minus minimum QT interval in a lead. The correlation between QT dispersion and the athletes demographic characteristics revealed that significant correlations existed between QT dispersion and age, SBP, DBP, MBP, body temperature and duration of athletic activity (DAA) [P < 0.05]. Similarly, no significant correlation existed between QT dispersion and Heart rate, height, weight and body mass index (BMI). This showed that increased QT dispersion is found in Dynamic and Static group of athletes and is significantly related to duration of athletic activity. This finding could be used for the identification of athletes at high risk of sudden death.

Abstract
Although fast green (FG) is widely used as food colorant by the cosmetics and drug industries, there is no evidence about whether FG affects leukocytes. The aim was to investigate the effect of FG on leukocytes. Male albino mice were subdivided into five equal groups: four of them were given 125, 250, 375 and 500 mg kg(-1) bw day(-1) FG in drinking water for 44 days. The fifth (control group) was given pure water only. During the experimental period changes in body weight, lymphoid organs weight (absolute and relative) as well as the total count and viability of lymphoid cells for the treated groups showed that FG was an immunotoxic agent. The structural effects induced by FG on thymocytes and splenocytes were investigated through measurements of their dielectric spectra in the frequency range 20-100,000 Hz. The estimated dielectric parameters of the treated groups reflected the changes occurring to lymphocytes by FG administration and indicated that FG dye is an immunotoxic agent. It is shown that the dielectric methodology can be used for the identification of lymphocyte modification induced by food colorants.

Abstract
In the search for low-metallic land mines, the neutron backscattering technique may be applied if the soil is sufficiently dry. An advantage of this method is the speed of detection: the scanning speed may be made comparable to that of a metal detector. A two-dimensional position sensitive detector is tested to obtain an image of the back scattered thermal neutron radiation. Results of experiments using a radionuclide neutron source are presented. The on-mine to no-mine signal ratio can be improved by the application of a window on the neutron time-of-flight. Results using a pulsed neutron generator are also presented.

Abstract
The applicability of a new irradiation facility for bulk hydrogen analysis based on the activation method using thermal and epithermal neutrons has been tested for cylindrical samples of 8 cm diameter and 10 cm high. A definite correlation was found between the relative excess flux values, R and the total hydrogen contents, N(H) of the samples. Analytical expressions obtained for R vs. N(H) function indicate the possible use of this method even in the case of approximately kg weight and liter sample dimensions. The large sample has a special advantage if the determination of the hydrogen concentration, C(H) is in question.

Abstract
In this study, two types of drinking water treatment facilities (two conventional drinking water treatment plants (DWTPs) and two compact units (Cus)) were compared referring to their production capacity. Water samples were collected from three main points: (a) different water treatment steps (b) washings of sand filters and (c) distribution system at different distances from the water treatment plants. Both viruses and protozoa were concentrated from each water sample by adsorption and accumulation on the same nitrocellulose membrane filters (0.45 microm pore size). Enteroviruses were detected by plaque infectivity assay in BGM cells and HAV, HEV and Norovirus were detected by RT-PCR. Giardia and Cryptosporidium were detected by conventional staining methods and PCR. The results revealed that enterovirus load at the intake ranged between 10-15 PFU/L for the two compact units and between 4.5 and 75 PFU/L for the two conventional DWTPs. The virus load in distribution system of the first type DWTPs at 1 km from the plant was the same as that of the intake. Viruses in the other type of treatment plants CUs at 1, 5 and 7 km, were much reduced. Investigation of raw water sediments of the two DWTPs showed enterovirus counts between 12 and 17.5 PFU/L. Virus count was reduced in sand of filters after washing. Giardia cysts were equally detected by microscopy and PCR in only intake samples of EL-Hawamdia CU (33.3%) and Meet Fares DWTP (50%). Cryptosporidium oocysts were equally detected by microscopy and PCR in intake samples of Abo EL-Nomros CU (100%), EL-Hawamdia CU (66.7%) and Fowa DWTP (50%). At Meet Fares DWTP three positive intake samples for Cryptosporidium were detected by PCR, compared with only two positive samples by microscopy. Giardia cysts and Cryptosporidium oocysts were detected in raw water sediment and sand of filters before washing. Only one sample from Meet Fares DWTP sand of filters after washing was positive for both Giardia and Cryptosporidium. It can be concluded that the poor microbial quality of the water may be due to improper operational skills and management of the various water treatment plants (especially at the two high capacity treatment plants).

The essential oil of M. ericifolia contained methyl eugenol (96.84%) as a major constituent, whereas M. leucadendron was rich in 1,8-cineole (64.30%). The essential oil of M. armillaris was rich in 1,8-cineole (33.93%) followed by terpinen-4-ol (18.79%), whereas M. styphelioides was rich in caryophyllene oxide (43.78%) and (-) spathulenol (9.65%). The essential oils of these species possessed antimicrobial and antifungal activities. M. ericifolia exhibited the highest inhibitory effects against Bacillus subtiles and Aspergillus niger. The antiviral activities of the essential oils against Herpes simplex virus type 1 (HSV-1) were studied in African green monkey kidney cells (Vero) by a plaque reduction assay. The volatile oil of M. armillaris was more effective as a virucidal (up to 99%) than that of M. leucadendron (92%) and M. ericifolia (91.5%). The effects of the essential oils on the antioxidant system status in carbon tetrachloride treated animals were studied. The essential oil of M. armillaris exhibited a marked antioxidant effect, it improved vitamin E, vitamin C and superoxide dismutase parameters so it can be used as a free radical suppressor.

Abstract
A new myxosporean parasite, Myxobolus stomum n. sp., is described from the oral cavity and lips of the blackspotted grunt Plectorhynicus gaterinus (Forsskal, 1775) in the Red Sea, Egypt. The parasite was observed as tiny aggregates of whitish cysts hardly noticed within the muscles of the oral cavity, especially within the lips. The spores were subspherical and measured 8.5x6.5 microm. Polar capsules were equal, pear-shaped, occupied about half of the spore length and measured 4.4x2.4 microm. Histological evaluation of the infection revealed no significant impact on the host. The ultrastructure of the plasmodial wall and sporogenesis of the present species followed the usual pattern valid for most studied myxosporean species.
