ABSTRACT

Reactivation of cytomegalovirus [CMV] has been reported in critically ill patients [especially elderly] lying in the intensive care units. So identifying such patients to treat is important. To detect the frequency of CMV infection in mechanically ventilated patients, and its correlation with patients' risk factors, and outcomes. The present study was carried out on 51 mechanically ventilated patients admitted to the Respiratory [20] and Geriatric ICU [31] of the Ain Shams University hospitals over a 3 month period. Serum CMV load was measured by real-time PCR. The overall rate of active CMV infection by RT-PCR among the studied populations was [68.6%], [77.4%] in patients of geriatric ICU versus [55%] in respiratory ICU patients. Comparison between CMV positive and negative cases showed a significant difference in the duration of mechanical ventilation and mortality rate. A statistically higher CMV load was recorded in respiratory ICU patients admitted due to exacerbation of chronic respiratory disease or stroke and developing ventilator associated pneumonia [VAP] or septic shock. Also there was a significant direct correlation between CMV load and age of the patient, duration of mechanical ventilation and duration of ICU stay CMV infection is frequent in mechanically ventilated critically ill patients especially the elderly. It is associated with poor outcomes, leads to increased mortality and morbidity in terms of increased ICU stay, longer duration of mechanical ventilation, and higher rates of nosocomial infections

ABSTRACT

Callus cultures were initiated from leaf of Cassia bicapsularis L. on solid Murashige and Skoog [MS] basal medium supplemented with different growth regulators. Excellent growth of callus was obtained in medium supplemented with 1 mg/l 2, 4-dichlorophenoxyacetic acid [2, 4-D] and grown in the dark. The obtained callus was subcultured every 4 weeks in the dark at 25°C. The Callus was compact, yellowish brown in color and used for establishment of cell suspension cultures. Maximum growth of suspension cultures was achieved in medium supplemented with 1 mg/l 2, 4-D and 0.1 mg/l kinetin. The growth rate of cells was initially slow but as the cultures proceeded, the growth increased significantly over a period of 22 days then the growth of cells was stable for 35 days

ABSTRACT

To investigate the role of toxoplasmosis in abortion of goats in Egypt, a total of 130 balady goats [2-3 years old], were used for this study. ELISA kit was used for detection of antibodies against T.gondii in does. Hematological, biochemical, and histopathological alteration were also used for diagnosis of natural Toxoplasma infection of goats. The results indicated that, out of 130 examined animals 67 [51,54%] were infected with T.gondii. The hematological findings revealed decrease in red blood cell count, packed cell volume, hemoglobin concentration [normocytic normochromic anaemia], and leukocytosis. The biochemical findings were significant decrease in serum total protein, albumin and globulin. Also, there was significant increase in ALT, AST, and ALP enzyme activity, urea and creatinine levels. The characteristic pathological lesion in aborted fetuses consists of focal or diffuse necrotic foci and infiltration with round cells in the brain, with other pathological alterations in lungs, heart, liver, kidney, spleen, and intestine. Toxoplasma organisms were demonstrated in these organs as single trophozoites, or within the cysts. The results indicated also, that clinic-pathological examination supported serologically by ELISA could be useful for diagnosis of toxoplasmosis in goats. Public health aspects of T. gondii infection in goats were discussed as well

ABSTRACT

To assess if thrombocytopenia has a predictive value for bleeding and/or liver decompensation following percutaneous radiofrequency ablation [RFA] therapy of hepatocellular carcinoma [HCC] in patients with liver cirrhosis. 64 consecutive patients with cirrhosis complicated by hepatocellular carcinoma, and associated with mild thrombocytopenia ranged from 37 to 99 x 10[9] platelets/L, and had undergone percutaneous RFA for treatment 86 hccs, were retrospectively studied. Nine possible factors were analyzed for their ability to predict bleeding or liver decompensation using the Cox proportional hazards regression model; Age, sex, Child-Pugh class, etiology of cirrhosis, platelet count, prothrombin activity, number of tumors, maximum size of the tumor, and type of electrode. It was shown that platelet threshold of 37 x 10[9]/L and the other variables were not significant risk factors of bleeding. Statistical [univariante and multivariente] analysis revealed that liver decompensation was clearly linked to prothrombin activity [p = 0,010 and p = 0.006, respectively] and < 63% of prothrombin activity was found to be a significant threshold for the occurrence of liver decompensation [p = 0.003] confirmed by Cox model [p = 0.05] Mild thrombocytopenia > 37 x 109/L is not an independent risk factor of bleeding or liver decompensation after RFA therapy of HCC in patient with cirrhosis. However, in such situation a significant higher risk of liver decompensation followed the procedure was found in cases of prothrombin activity < 63%.Radiofrequency ablation, hepatocellular carcinoma, thrombocytopenia, prothrombin activity, liver cirrhosis RFA= radiofrequency ablation, HCC = hepatocellular carcinoma, US = ultrasonography, CT = computed tomography

ABSTRACT

Immunoserological differential diagnosis of Taenia spp. is the major contribution of the present work. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis [SDS-PAGE] was used to analyze the protein components of three Taenia extracts prepared from Cysticercus bovis, Taenia saginata and Taenia taeniaeformis. Antigenic components of the three taeniid antigens revealed by [SDS-PAGE] were: [I] Cysticercus bovis cystic fluid antigen: 180, 116, 90, 66, 45, 26, 17 and 10 kD. [II] Taenia saginata excretory secretory antigen [ES]: 198, 180, 146, 116, 55, 45, 35 and 26 kD. [III] Taenia taeniaeformis whole crude antigen 170, 140, 120, 116, 66, 55, 45, 35, 26, 17 and 10 kD. The characterized extracts were used as antigens in Western Blot [WB] technique. Sera from immunized rabbits with Cysticercus bovis fluid antigens were used in detecting a variety of immunogenic bands: [I] Cysticercus bovis: 160, 116, 86, 52, 45, 38 and 29 kD. [II] Taenia saginata: 86, 68 and 10 kD. [III] Taenia taeniaeformis: 170, 116, 86, 68, 52, 45 and 29 kD. The present results suggested that the diagnostic bands by Western Blotare 160 and 38 kD for Cysticercus bovis, 10 kD for Taenia saginata [ES] antigen and 170 kD for Taenia taeniaeformis

ABSTRACT

Evaluate the effect of omega-3 fatty acids [omega-3] on serum lipids [cholesterol and triglycerides] and blood pressure levels in osteoarthritis [OA] patients. 200 female OA patients from Assiut University Hospitals, were diagnosed according to the American College of Rheumatology criteria [ACR]. They were submitted to socioeconomic history taking, clinical and rheumatological examination and laboratory investigations. They were equally divided to four groups as follows: group [1]: patients were treated with physiotherapy only [control group]. [2]: patients treated with physiotherapy + omega-3 fatty acids [3 capsuleslday]. [3]: patients treated with physiotherapy + [5gm/day linseed oil]. [4]: patients treated with physiotherapy + [350 gm/week fishorsalamon]. Statistical analysis and nutrition education were applied Revealed that mean level of cholesterol was significantly reduced in the participiant OA patients at [P<0.01, P<0.000, P<0.05]. Also serum triglycerides concentration was significantly decreased in patients taking omega-3 fatty acids as linseed oil and fish [group 3 and 4]. The erthrocyte sedimentation rate [ESR] was significant decreased in OA patients taking omega-3 fatty acids [groups2,3,4]. Omega-3 fatty acids from capsules, or linseed oil or fish decreased the systolic blood pressure. Also it was clear that knee joints which are affected were the most common, while hip joints were the least

ABSTRACT

To evaluate the influence of UV-B radiation on the cornea and epithelial cells of the albino rat. 100 Sprague-Dawely rats were divided in 4 groups with different ages [3, 6, 10, 18 weeks] and control one. Exposed 4 groups were irradiated to UVB with wave length 300nm and intensity of 8 kj/m2. Each group was divided into 2 sub-groups [A and B] according to the time of exposure [15 and 30 minutes]. The control group [C] was divided into 5 rats for each group. One week after exposure cornea was removed to evaluate the histopathological changes. Groups were compared by evaluating the difference between exposed and non-exposed cornea. Exposure to 15 minutes UV-B showed degenerative changes in all ages and increased with time of exposure. Epithelial hyperplasia was 25% in 6 weeks group exposed to 15 minutes of UV-B and 33.3% with 30 minutes of exposure. In 18 weeks group hyperplasia was 25% after 30 minutes of exposure. Epithelial thinning was detected only in 3 and 18 weeks groups after exposure to 30 minutes of UV-B by 33.3%. Epithelial erosion was 16.6% in 10 weeks group after 30 minutes of exposure. Stromal blood vessels were detected in exposed groups to 30 minutes of radiation in 6, 10 weeks by 16.6% and 41.6%. Stromal edema was detected in all ages exposed to 15 and 30 minutes of UV-B. Exposure to UV-B comeal epithelial and stromal changes which increase with time of exposure

ABSTRACT

To investigate the effects of UVB radiation on the crystalline lens of the rat lens. 100 Sprague-Dawely rats were divided in 4 groups with different ages [3, 6, 10 and 18 weeks] and control one [20 rats in each group]. Exposed 4 groups were irradiated to UVB with wave length 300nm and intensity of 8kj/m2. Each group was divided into 2 subgroups [A and B] according to the time of exposure [15 and 30 minutes]. The control group [C] was divided into 5 rats for each group. One week after exposure, both lenses were removed for morphological changes and for histopathology. Groups were compared by evaluating the difference between exposed and non-exposed lenses. Early cortical cataract [vacuoles] was not detected in all [B] groups, and appeared in all [A] groups As except E4 group. Cortical cataract appeared in both exposed groups and the increased with age. Equatorial cataract was detected in all ages and the incidence increased in rats of [A] groups. Sutural cataract was more in young groups and the incidence increased with time of exposure to UV-B it was not detected in E4 group. Early nuclear and nuclear cataract was more in young ages and increased time of exposure. UV-B has powerful effects on the rat lens and development of different types of cataract, which differs according to the age and time of exposure. The more exposure to UV-B the more the cataract develops

ABSTRACT

This study aimed to evaluate the effect of hematopoietic growth factors [erythropoietin and granulocyte colony stimulating factor] on liver regeneration after partial hepatectomy and bone marrow suppression of rats and to investigate the role of hematopoietic stem cells in liver regeneration by assessment of CD 34+ hematopoietic stem cells marker in hepatic tissues. 36 adult male albino rats were used in this study and were divided into six groups each of 6 rats: the 1st is the control group, the 2nd is bone marrow suppression group, 3rd is subjected to partial hepatectomy, 4th is subjected to bone marrow suppression by benzene, then 70% partial hepatectomy, 5th is subjected to 70% partial hepatectomy with injection of Eprex and Neupogen at time of partial hepatectomy, then daily for 5 days post hepatectomy and the 6th group is subjected to bone marrow suppression by benzene first then 70% partial hepatectomy with injection of Eprex and Neupogen daily for 5 days post hepatectomy. Histological evaluation and immunohistochemical study for CD34+ cells in the hepatic tissues were assessed. There were no regenerative changes in both control and benzene treated groups. There were little regenerative changes in the group of partial hepatectomy after benzene treatment but in the groups that were treated with the hematopoietic growth factors. These regenerative changes were increased especially in the treated group after partial hepatectomy than treated group after partial hepatectomy and bone marrow suppression. Immunostaining of CD34 expression as marker of HSCs in liver sections showed the following; the normal group, benzene treated group and partially hepatectomized group after benzene treatment showed no expression, but partially hepatectomized group show focally positive expression. Both groups treated with hematopoietic growth factors either after partial hepatectomy or after partial hepatectomy and bone marrow suppression by benzene show diffusely positive expression. The present study had shown that Erythropoietin and Granulocyte colony stimulating factors stimulate regenerative process occurred in the liver after partial hepatectomy only and after partial hepatectomy with bone marrow suppression either by endogenous mechanisms or by mobilization of hematopoietic stem cells

ABSTRACT

The liver has a remarkable capacity to regenerate after injury. Within a week after partial hepatectomy [PH] hepatic mass is back essentially to what it was prior to surgery. Hematopoietic stem cells [HSCs] may contribute in the regeneration and the renewal capacity of hepatocytes. To investigate the origin of hepatocytes in liver regeneration whether from resident hepatic stem cells or from circulated HSCs after suppression of HSCs from bone marrow by Benzene This experimental study included 24 adult male albino rats. The studied animals were divided into 4 groups; first group [control group] was included 6 normal rats. No intervention was carried out to this group of rates. Second group [PH] group] was included 6 rats in which 70% PH was done. Third group [Benzene group] was included 6 rats of in which bone marrow [BM] suppression was carried out by Benzene injection. Ten injections were performed subcutaneously in a period of 3 weeks for induction of BM suppression. Fourth group [Benzene+ PH group] was included 6 rats in which BM suppression was carried out as 3rd group. Seventy percent PH was then done to them. Cytological changes during regeneration were assessed in all groups by; the number of binucleate cells and the restored number of hepatocytes. Mitotic index was performed in the second and the fourth groups. The percent of regeneration was also calculated. Immunohistochemistry technique was used for detection of CD34+ cells markers in liver tissues by using anti CD34+ cells antibodies [this technique is done in group 4 only]. Our results found that mean weights of rats and assumed liver weights, there were no statistical significant differences between the studied groups. PH group had shown higher regeneration rate than Benzene+ PH group; the former showed a mean loss of 19% [81 +/- 2.1% of regeneration] of their original weight by the end of the first week, and the latter a mean loss of 30% [70 +/- 0.7% of regeneration]. Number of binucleate cells there was a significant difference in benzene treated group compared to control group [p<0.05]. Mitotic index there was significant higher mitotic index in partially hepatectomized after bone marrow suppression by benzene than partially hepatectomized group [p<0.05]. We had used CD34 [CBRE8] antibody in our. It is indicated that the hepatocytes can regenerate the liver and restore its original size. Hematopoietic stem cells may habitat the endothelial cells in the liver. Their role in hepatic regeneration doesn't appear early after partial hepatectomy it mobilized from bone marrow to the damaged liver rlay in the liver tissues for long time [> 7 days] then differentiate into non parynchematous liver tissues

ABSTRACT

Many studies were performed to evaluate the effects of static magnetic fields [SMFs] on the processes of proliferation and migration of cerebellar cells to their final postnatal destinations. Granule cells are the most abundant interneurons in the cerebellum. Progenitors of these neurons actively proliferate during the first 2 postnatal weeks in external granular layer [EGL]. The granule cells in the EGL migrate inwards to form the internal granular layer [IGL], and the EGL disappears. So the postnatal development of the cerebellum depends on their postnatal proliferation and migration which is vulnerable to any micro-environmental insult. to evaluated the light and electron microscopic changes occurred to the cerebellar granule cells of the pups after postnatal exposure to SMF [20 mT]. Postnatal exposure to SMFs showed that there was a significant thinning in the EGL at the beginning of the study at postnatal thy 4, this significant decrease in thickness progressed in the first week. At two weeks when normally the EGL starts to disappear, it showed persistent increase in its thickness indicating delayed migration. At all ages of exposed group [P], EGL contained many apoptotic cells and some degenerated cells. IGL showed significant decrease in its cellular density till the postnatal day 15 concomitant with the period of delayed migration in the EGL. At the postnatal days 22, the cells in IGL began to regain its near normal cellular density but the IGL showed disarrangement of its crowded granule cells with absence of appearance of regular glomeruli among them with appearance of some degenerated cells among the granule cells. Many cells of the IGL also showed areas of cytoplasmic vacuolation. Postnatal exposure to SMFs produces some delay in the development and appearance of more apoptotic cells. But some of these changes in different stages of the postnatal development of the cerebellar cortex began to be less apparent with advancement of age

ABSTRACT

Many studies were performed to evaluate the effects of static magnetic fields [SMFs] on the processes of proliferation and migration of cerebellar cells to their final postnatal destinations. Purkinje cell [PC] as one of the most critical station for all afferent input to the cerebellum as well as the major output from the cerebellum either direct or indirect through the other cerebellar neurons and development of Purkinje cells depends on their postnatal migration which is vulnerable to any micro-environmental insult. To evaluate the light and electron microscopic changes occurred to the cerebellar PCs of the pups after prenatal exposure to SMF [20 mT]. Prenatal exposure showed a significant decrease in the number of PCs as compared with that number in the control group throughout the time of study with appearance of some pathological changes at the cellular level obvious from the postnatal day 4 till the end of the study, as there were many apoptotic cells, few cells degenerated with astrocytosis near the Purkinje cells with large cytoplasmic vacuoles inside the cells and many cells became atrophied cells. The prenatal exposure to static magnetic field led to decrease ability of the proliferation, delay in the development and appearance of some degenerative changes in different stages of the postnatal development of the cerebellar cortex and these changes persisted till the adult life

ABSTRACT

Three new simple, different and sensitive spectrophotometric methods are suggested for the determination of Dropropizine [DRO]. The first is based on the reduction of ferric into ferrous in presence of 0-phenanthroline by the mentioned drug to form a highly stable orange-red ferroin chelate[Fe-[Phen][3]][2+], measured at [lambda][max] 510.5 nm for zero-order [D[degree sign]] while the peak amplitude was measured at 537.5 the nm for the first derivative [D[1]] using distilled deionized water as a solvent. Beer's law was obeyed in the range of 0.5-2.2 micro g/ml for both D[degree sign] and D[1] with mean percentage recoveries of 100.08 +/- 1.370 and 100.03 +/- 1.064, respectively. The second method is based on the reaction of DRO with 7,7,8,8- tetracyanoquinodimethane [TCNQ] in acetonitrile solvent to form a highly stable charge transfer colored complex that was measured at 734.5 nm. Beer's law was obeyed in the range of 10-55 micro g/ml with mean percentage recovery of 99.93 +/- 1.070. The last method is based on the reaction of DRO with cerium [IV] ammonium sulphate in acidic medium to form a highly stable colored oxidative product that was measured at 486.5 nm. Beer's law was obeyed in a concentration range 145 - 335 micro g/ml with mean percentage recovery of 99.67 +/- 1.077. The optimum assay conditions and their applicability for the determination of the cited drug in pharmaceutical formulation were described. The proposed methods were statistically compared with the reported method revealing good accuracy and precision

ABSTRACT

Kidneys are the main excretory organ of the body, performing its function through elimination of nephrotoxicants as Cadmium [Cd]. We carried out this study to investigate the effects of vitamin E "alpha tocopherol", as an antioxidant compound, on Cd induced toxicity in the kidneys of albino rats. In experimental albino rats, intraperitoneal administration of Cd [0.4 and 0.6 mg/kg/day] for 12 weeks induced renal damage, which was evident from the increased levels of serum urea and creatinine with significant decrease in total proteins, body weight and hematological parameters. This was associated with a significant rise in Cd concentration both in kidneys and blood. Co-administration of alpha tocopherol as antioxidant resulted in improvement of the kidney functions. The present study suggests that the physiological, biochemical and cytoprotective potential effects of vitamin E in Cd toxicity might be due to its antioxidant properties, which could be useful for achieving optimum effects in treating Cd induced renal damage

ABSTRACT

The main objective of this study is to detect the changes might affect the elastic properties of large central arteries in normotensive offspring of known hypertensive parents, and to compare these changes to normal age-matched offspring of normal individuals. Also, to correlate age and gender effects on the results obtained. Arterial stiffening is associated with a number of known cardiovascular disease risk factors, raising the possibility that increased arterial stiffness may be a marker for advanced atherosclerotic vascular disease. The vascular dynamics of children with a parental history of hypertension is a cornerstone of early detection of functional and morphologic abnormalities of the arterial wall that may be responsible for many cardiovascular and cerebro-vascular complications in their future life. The study includes sixty subjects [ages 15-30 years], all were clinically healthy by applying exclusion criteria, full history and clinical examination. They are divided based on their family history of hypertension into two groups, group-I 30 offspring with a parental history of hypertension and group-Il 30 off-spring of normotensive parents. All subjects were evaluated to obtain systolic, diastolic and pulse pressure readings then, M-mode echocardiography is done to study their aortic elastic properties. After collection of both clinical [blood-pressure] and Echocardiographic data, analyses of the results revealed a significant elevation of all blood pressure parameters in group-I than group-Il with systolic Bp of mean +/- SD [118.5 +/- 9.7 in group-I versus 106 +/- 4.9 mmhg in group-Il], diastolic Bp [66.8 +/- 5.7 for group-I versus 62.8 +/- 8.0 mmhg in group-II] and a net increase in pulse pressure in group-I than group-Il [51.6 +/- 10.5 versus 43.1 +/- 6.2]. Comparing aortic diameters of two groups revealed that, a non-significant increase in systolic diameter in group-I [p=non-significant], significant increased diastolic diameter in group-I with mean +/- SD [29.8 +/- 2.3 versus 28.0 +/- 1.3 mm in group-II, p=0.01]. Group-Il subjects exhibit an increased Ao-diameter change property with mean +/- SD [3.7 +/- 0.4 versus [2.6 +/- 0.5 mm in group-I] reflecting impression of enhanced their aortic elastic feature. Comparing aortic stiffness parameters in between the two groups revealed a significant [p=0.001] difference in all parameters. Group-I showed decreased aortic strain, decreased distensibility and increased aortic stiffness in relation to group-II with Ao-strain of mean +/- SD [8.9 +/- 1.8 in group I versus 13.4 +/- 1.6 for group-II], Ao-distensibility [3.1 +/- 0.8 in group-I versus 5.0 +/- 1.1 cm2 dyne-1 in group-Il], and Ao-stiffness is [0.21 +/- 0.02 in group-I versus 0. 12 +/- 0.02] in group-Il. In a trial to study the effect of blood pressure on aortic stiffness, It was found that, systolic blood pressure is positively correlated to increased aortic stiffness, with p-value of 0.001 and coeffIcient correlation r 0.66 and is negatively correlated to both aortic strain and distensibility [p value 0.001, r - 0.61 and p 0.001 and r - 0.57] respectively. Correlation made to study the effect of age and gender on Ao elastic properties revealed that, there's a positive age related increased aortic stiffness [p value = 0.02, r 0.28] and a negative correlation to aortic distensibility [p = 0.01, r - 0.32]. Detection of the effect of gender variation on the results was obvious in group-I as males were found to have a significantly [p=0.001] higher Ao stiffness than females with mean +/- SD [0.20 +/- 0.002] in males versus [0.14 +/- 002] in females. Females are found to have a significant higher aortic strain and distensibility [p=0.001 for strain and 0.03 for distensibility] with mean +/- SD Ao strain [12.2 +/- 2.3 for females and 9.7 +/- 2.9 for males], however, Ao distensibility was [4.4 +/- 0.9 for females and 3.6 +/- 1.7 for males]. Group-I was found to have a higher PP and less change in Ao diameters between systole and diastole, and this is reflected on increased Ao stiffness parameters in their results with lower distensibility and strain. Age is found to be highly correlated to increased Ao stiffness and decreased distensibility. Also, males possessing a higher than females Ao stiffness results

ABSTRACT

The study based on assessment of changes in left ventricular dimensions and mass in Type-II diabetic patients and to correlate the effect of plasma insulin and serum glucose levels on changes might affect the Lv in absence of increased systemic blood-pressure Hyperglycemia, insulin resistance, cytokines, and vasoactive hormones are the most important factors that lead to advance and progression of abnormal cell growth. Like hypertension, diabetes can cause fibrosis of the myocardium and increased collagen deposition in absence of systemic hypertension or other causes of Lv hypertrophy. The study includes 44 patients previously diagnosed as normotensives type-Il diabetis and after applying exclusion criteria, they are divided into Four-groups based on the treatment protocol [orall or insulin] and the state of glycemic control [controlled or uncontrolled]. Group-I [controlled diabetics on oral theray], included 10 patients with their age of mean +/- SD [44.0 +/- 5.2], Group-Il, [uncontrolled orally treated diabetics], included 12 patients with age of mean +/- SD [46 +/- 4.2], Group-Ill [controlled diabetic on insulin therapy], included 9 patients with their age of mean +/- SD [45 +/- 4.1], and Group-IV [uncontrolled insulin treated diabetics], included 13 patients with age of mean +/- SD [45 +/- 3.8]. All patients in all groups were subjected to [full clinical evaluation and routine examination, laboratory assessment of basal glucose and insulin serum levels after 8-hours of no calorie intake, estimation of insulin-resistance indices by Glucose/Insulin ratio and HOMA test was meticulously analyzed, then M-mode Echocardiographic assessment of Lv-diastolic dimensions to estimate Lv-mass and mass index in relation to their body surface area]. After collection of both laboratory and Echocardiographic data, analyses of the results revealed that, in demographic features there's no significant variation of age in between all groups, however, body weight was significantly increased in group III than other groups with [p=0.001], and no significant variation of body height and BSA among all groups. Comparing the laboratory data between group I to group III- [controlled diabetics] revealed that, there's a significant variation in all laboratory data between both groups in the form of; higher FBG, basal insulin, HBA1C, and HOMA with significant lower G/I in group III versus group I with p=0.001 for all apart from p=0.05 for HBA1C only. Moreover, comparing laboratory data between uncontrolled-diabetic groups [group II and IV] revealed that, there's a significant variation in all laboratory data between both groups in the form of; higher FBG, basal insulin, HBA1C, and HOMA with significant lower G/l in group IV versus group II with p=0.001 for all results. Comparing Echocardiographic data revealed that, there's no significant variation in all Echocardiographic data between controlled diabetic groups [group I and III] with septal thickness, [0.9 +/- 0.22 in group I vs 0.93 +/- 0.11 in group III], LVEDD [45.4 +/- 6.6 in group I vs 48.5 +/- 1.5 in group III], posterior wall thickness [0.97 +/- 0.21 in group I vs 0.86 +/- 0.01 in group III], Lv mass [168.8 +/- 21.17 in group I vs 179.1 +/- 32.4 in group III] and Lv mass Index [91.2 +/- 10.8 in group I vs 85.4 +/- 17.5 in group III]. However, comparison between uncontrolled groups [group II and IV] revealed that, in spite of there's no significant variation in relation to LVEDD and PWT. there's a significant [p=0.03] increased septal thickness in group IV than group II [0.9 +/- 0.17 in group II vs 1.15 +/- 0.11 in group IV] and a significant [p=0.03] increased Lv mass and mass index in group IV [lv mass 196.5 +/- 25.4 in group II vs 232.4 +/- 27.8 in group IV Lv mass index was 101.3 +/- 15.0 in group II vs 120.4 +/- 13.5 in group IV]. Correlation of laboratory data to Echocardiographic findings between controlled and un-controlled groups revealed that, there's a positive correlation of increased Lv-mass and mass index with higher basal glucose [P 0.018 and r 0.355] and insulin levels [P 0.001 and r 0.48]. Also, positive correlation with elevated HBA1C [P 0.001 and r 0.71], elevated HOMA level [P 0.001 and r 0.477]. However, negative correlation with G/I Ratio [P 0.02 and r - 0.34]. Laboratory data revealed a significant variation in all parameters between controlled and uncontrolled diabetics in relation to basal levels of glucose and insulin and more evidenced insulin resistance in uncontrolled groups, which means that, in uncontrolled glycemic state there's more increase in glucose and insulin levels with resultant more insulin resistance whatever the mode of treatment [oral or insulin]. Echocardiographic data revealed that, no differences in between controlled diabetics but, a significant increased septal wall thickness is observed in uncontrolled groups with resultant increased in their Lv mass and mass index and this conclude that, in uncontrolled glycemic state, their a tendency to increased Lv mass in spite of the mode of treatment [either oral or insulin]. Elevated fasting blood glucose, basal insulin, HBA1C, HOMA and reduced glucose/insulin ratio are highly correlated to increased Lv mass and mass index and this is not related to either controlling blood glucose or the mode of treatment oral or insulin

ABSTRACT

Capillaria philippinensis is a zoonotic nematode that causes severe diarrheal syndromes in humans. C. philippinensis coproantigen and egg antigen were fractionated using SDS-PAGE. Several protein bands were detected in both antigens. Protein profile of coproantigen of C. philippinensis infected patient included wide range of bands ranging from 10- 180 kD. Protein profile of egg antigen revealed only few bands detected at 10, 34- 36.5, and 148 kD. Using Western blot, a variety of protein bands were recognized by the infected patient serum. When tested against coproantigen, it detected a wide range of antigenic proteins at different molecular weight [10, 14, 34-36.5, 48, 54, 62, 66, 86, 94, and 148 kD respectively]. None of these bands were detected in normal human feces. When tested against egg antigen, the infected patient serum detected only two faint antigenic bands at 62 and 66 kD. It is concluded that coproantigen was more convenient than egg antigen in diagnosis of capillariasis by WB

ABSTRACT

Needle stick injuries are an important and continuing cause of exposure to serious and fatal diseases among health care workers [HCWs] who suffer daily accidental occupational exposure to needle stick injuries during the course of their role of caring for patients to determine the burden of needle stick injuries, its causes and knowledge related to it among HCW participating in an infection control training program at Minia University Hospital [MUH]. A well-structured pre- and post-training questionnaires about general infection control knowledge was used and included also 10 basic knowledge questions and inquiries about incidents of needle sticks, its frequency and cause, and history of hepatitis B vaccination. A total of 278 physicians and 56 dentists participated in this study. Dentists were younger than physicians, and had a slightly higher knowledge score than physicians. We found that 63.2% of the participating physicians and dentists experienced at lease one needle stick during their practice. About 61% and 71.4% of the physicians and dentists experienced at lease one needle stick during their practice, respectively, suggesting that dentists were more likely to be exposed to needle stick injuries than physicians. The overall mean of needle stick injuries per year among the participants was 4.42 [ +/- 1.83]. However, the average numbers of sticks were 4.51 [ +/- 1.87] and 4.03 [ +/- 1.77] among the participating physicians and dentists, respectively. Self-inflicting injuries during bending or recapping of a used needle was the most frequent cause of needle sticks [41% for physicians and 59% for dentists]. Nearly 72% of the participants were categorized as excellent in basic knowledge regarding infection control. Also, knowledge of needle stick management significantly improved by 63.3% and 7.8% post-training among dentists and physicians, respectively. Importantly, as the knowledge score increases, the liability to be injured by needles decreased. On the other hand, physicians were three times more likely to be vaccinated against Hepatitis B virus [HBV] than dentists although the overall vaccination rate was very low [15.2% vs. 4.2% among physicians and dentists, respectively]. needle stick injuries are common among HCW of MUH and recapping and bending of needles are prevalent inappropriate practices that increase the likelihood of needle sticks. Ensuring that HCW are properly trained on safe use and disposal of sharps will make this practice safer
