Spectral studies of complexes of some trivalent transition metals with isonitrosodibenzoylmethane and isonitrosothiodibenzoylmethane

The complexes of isonitrosodibenzoylmethane and isonitrosothiodibenzoylmethane with Cr [III], Fe [III] and Go [III] were synthesized and analytically characterized. In terms of the IR and Nujol Mull Spectra of the respective chelates, the mode of bonding and the stereochemistry of the investigated systems were discussed

Spectral, thermal and electrical characterization of Fe [II] 1,3 diphenyl-2-oximo-1,3 propandione with some heterocyclic bases

Iron [II] complexes of the type Fe [II] L2 B2 where L: 1,3 diphenyl 12-oximo- 1,3- propandione and B : pyridine, thiophene or furane, were synthesized and characterized by IR, DTA and electrical conductivity measurements. The presence of the respective heterocyclic bases help to stabilise the oxidation state of Fe [II] during its interaction with concerned oxime -1,3- diketone. The obtained data suggested the following descending order of relative thermal stability of the concerned adduct complexes. Fe [II] L[2] [Pyridine][2] > Fe [II] L[2] [Furane][2] > Fe [II] L[2] [Thiophene]. Furthermore, both of the thiophene and furane adduct complexes exhibited Semiconducting character in the temperature range 30-130 degree. Fe [II] L[2] [pyridine][2] showed such semiconducting behaviour only up to 90 degree. The calculated values of the activation energy of the electrical conductivity decreased in the following order: Fe [II] L[2] [Furane][2] > Fe [II] L[2] [Pyridine][2] > Fe [II] L[2] [Thiophene][2]

Pulmonary artery flow morphology echopatterns in patients with deep vein thrombosis

The present study comprised 25 patients with deep vein thrombosis [DVT] [13 males and 12 females, 22 - 70 years old] and 15 healthy individuals of matched age and sex as a control group. The patients were divided into two subgroups: 15 patients with first time DVT and 10 patients with recurrent DVT. According to the criteria already suggested by the American Society of Echocardiography, the patients with first time DVT had a significant increase in pulmonary embolism [PE] scoring and a highly significant pulmonary embolism suspicion index [PESI] in comparison to patients with recurrent DVT. Also, there was highly significant changes in the following Doppler echocardiographic indices: RVPEP/RVET ratio, RVAcT/RVET ratio and RVPEP/RVAcT in the whole test group and its two subgroups in comparison to control group. This findings pointed to the presence of pulmonary hypertension in the cases with first time DVT with or without clinical evidence of pulmonary embolism, and it was recommended to use this non-invasive Doppler echocardiography indicated for the evaluation of patients of DVT with or without suspicion of pulmonary embolism

Incidence of organic tricuspid valve affection among rheumatic valvular heart diseases

Among the 545 patients with rheumatic valvular affection evaluated by Doppler Echocardiography; 56 were to have associated organic TV affection [10.28%]. They were 307 females of whom 29 have associated TV organic affection [9.4%] and 238 males of whom 27 have associated organic TV affection [11.34%].The echocardiographic features refIecting organic TV affection found among our studied cases were refIecting thickening [100%]; dooming [78.0%]; prolapse [12.5%]; calcification [3.75%]; subvalvular chordal thickening [19.86%] and restricted valve mobility[9.55%]. Associated organic tricuspid valve was found to be more prevelent among cases with combined aortic and mitral valve lesions [13.3%] especially those suffering from double mitral and aortic valve lesions [19.05%] as well as among those with isolated mitral stenosis [11.42%]. Tricuspid regurge was found in [10.28%] among the studied cases [9.4%among males and 11.34% among females]. Tricuspid stenosis was found in only 7.5% [in 7.6% among males and in 1.5% among females]. Significant TS was found in 2.75%; [in 3.5% among males and 2.0% among females]. There is no sex difference for the prevelance of organic TV affection among our studied rheumatic valvular heart cases; however, Significant TS is more common in males than females. In conclusion; Rheumatic TV disease is common in association with other valvular affection, it never occur as an isolated condition; TS always associated with TR. There is a high incidence of organic TV disease among males with rheumatic valvular lesion than females which requires further studies and analysis

Glucose tolerance curve after a honey load versus matched amount of sugars

The effect of honey on glucose tolerance curve versus matched amounts of glucose and artificial formula was studied in diabetic patients. Results indicate that honey is more tolerable than pure glucose or an artificial formula of honey sugars. This is true in normal subjects and adult onset diabetes, honey could replace sugar as a sweetening agent. Unfortunately this beneficial effect of honey is not found in juvenile onset diabetics

Ultrasonographic assessment of the portal vein in patients with portal hypertension

The aim of the present study was targeted toward the assessment of the state of the portal vein in cases of portal hypertension, to estimate the actual incidence of portal vein thrombosis in this cases and evaluate the role of this non invasive technique for the diagnosis and management of patients. The material of the present study comprised 54 patients clinically suggested to have portal hypertension 50 males and 4 females. Their age range from 20 to 65 years with mean value 39.71 years All patients were subjected to thorough history taking full clinical examination, routine laboratory investigations and ultrasonograghic examination The portal vein was dilated in 81% of the patients in the bleeder subgroup while in the non bleeder group all patients have dilated portal vein. On comparing the portal and splenic vein calibers in different groups we found that non ascitic have larger calibers than asctic subgroup. Also our patients with portal vein thrombosis have a larger portal vein diameter than non thrombolic cases and those with huge spleen caliber than those with moderately enlarged one. Our results perhaps could select the splenic vein caliber to be a more sensitive usher of bleeding rather than the portal vein. In our cases with portal hypertension we found that no cirrhotic patients had portal vein thrombosis except those subjected to pervious splenectmy or having a complicating liver cell carcinoma. Duplex Doppler ultrasonograghy had offered a confirmation of portal vein thrombosis and revealed 100% hepatoperal blood flow in the portal vein and 81% hepatofugal blood flow in the splenic vein. In conclusion, ultrasonograghic technique had definitely offered a non invasive method for assessement of the state of the portal vein, although it has mentioned some peculiar feature it have not answered much of questions that have been aroused as regard the syndrome of portal hypertension with its different intermingled parameters

Paradoxical interventricular septal movement in patients with bilharzial cor-pulmonale without clinical or phonocardiographic evidences of pulmonary and/or tricuspid regurge

* Twenty eight patients with bilharzial corpulmonale showing no clinical or phonocardiographic evidences of pulmonary and/or tricuspid regurge were the material of the present study. * Interventricular septal motion was studied in all cases and echocardiographic scoring of the degree of pulmonary hypertension was obtained in them. * Abnormal or paradoxical septal motion indicating diastolic overload to the right ventricle was observed in 20%, 22% and 43% of cases with mild, moderate and severe degree of pulmonary hypertension. * Diastolic overloading in these cases is probably due to incipient and clinically occult pulmonary and/or tricuspid regurge whose murmur in beyond the range of human ear audibility. * The presence of diastolic valume overloading in patients of bilharzial cor-pulmonale as evidenced by paradoxical septal motion in the absence of clinically demonstrable pulmonary and/or tricuspid regurge should destract the attention to incipient regurge of either valves
