Infestation status of Aega psora [Linnaeus, 1758] [Isopoda, Cymo-thoidae] skin parasite of the marine fish, Sardine [Sardinella gibbosa] of Port Said Mediterranean Coastal Zone, Egypt

An isopod parasite of family Aegidea was collected from marine fish, Sardinella gibbosa [new hosts] over 2-years period from 2007 to 2008. The fish hosts were captured in the coastal waters of Port Said, Egypt. The Cymothoa sp. and Aega sp. were only collected from skin of the new host, Sardinella gibbosa, and described on the basis of female specimens. The morphological characteristics of were discussed in details. Comparing the present specimens with the previously reported Aega sp. showed that the present material belongs to the type species of the genus: Aega psora [Linnaeus, 1758]. Monthly and seasonal patterns in infestation rates [N==593, W +/- SD [range] =50.09 +/- 3.8 g]. Parasitic specificity and prevalence are given Mean prevalence, P = 24 +/- 5.5 and mean intensity, MI +/- SD =28.44 +/- 16.19 and total number of infestation were estimated 59[10.35]

Levels of helminthic infections in the quails coturnix coturnix from kingdom of Saudi Arabia

The present study aims to clarify the difference of the intensity of parasitic infection between the domestic quails Coturnis coturnis and the migrant ones. A total of 60 domesticated and 60 migratory quails were investigated during the migration season September-November 2009 for intestinal parasites. Investigations revealed that both domestic and migrant quails were susceptible to infection with three helminth parasites; a nematode [Heterakis gallinaruni], and two cestodes [Choanotae-nia infundibulum and Hymenolepis sp.]. The prevalence of infection in the migratory males was higher than the female ones, the opposite results was obtained for the domestic birds. The differences in the prevalence were found to be statistically significant in case of the domestic birds. Single infection showed the highest prevalence followed by the double infection and finally the triple infection. The mean intensity of infection in the female domestic and migrant C. coturnix was higher than male

Histological, histochemical, immunohistochemical and morphometric study of adult male albino rat's lung following exposure to air pollution

Exposure to air pollution is associated with increased respiratory and cardiovascular morbidity, although the underlying mechanisms are unclear. Thus the way of assessing the effects of inhalation of whole mixtures from defined sources as tobacco smoke and car exhaust need lobe considered more. To investigate using histological, histochemical, immunohistochemical and morphometric study, the harmful effects of tobacco smoke and car exhaust on adult male albino rats' lung and the influence of arrest of these air pollutants. Thirty adult male albino rats were randomly divided into three groups: control group, tobacco exposed group, and car exhaust exposed group. Rat's general condition and behavior were noticed and they were weighed at the beginning of research and at the time of sacrific, Paraffin sections were prepared for histological, histochemical, immunohistochemical using marker CD44 and morphometric study and statistical analysis were done. Rats exposed to tobacco smoke or car exhaust showed significant decrease in body weight more intensified after car exhaust which remained significantly less than control rats after arrest of exposure. Histological. histochemical, immunohistochemical and morphometric changes were more exaggerated after car exhaust than after tobacco exposure. Rats showed pulmonary congestion, extravasation of blood in lung alveoli, perivascular infiltration and thickened interalveolar septa, obliteration of most alveoli and subsequently compensatory emphysematous changes. There was increased deposition of collagen fibers and apparent increase in niucopolysaccharides and immunohistochemical reaction CD44. Arrest of exposure to either tobacco smoke, or car exhaust caused partial recovery which was less ameliorated after car exhaust. These results provide evidence that air pollution from either tobacco smoke or car exhaust are risky factors for parenchymal lung damage and marked thickening of the interalveolar walls. Partial recovery was observed after arrest of tobacco smoke better than after car exhaust

Effect of aspirin versus aspirin and vitamin C on gastric mucosa [fundus] of adult male albino rats. histological and morphometric study

Acetyl salicylic acid [Aspirin] is almost the most widely used drug both therapeutically [to reduce pain, inflammation and fever] and prophylactically [to prevent thrombotic events]. Aspirin [ASA] represents an important risk factor for gastric mucosal injury. The roles of active oxygen metabolites and anti-oxidative defenses in aspirin [ASA]-induced gastric damage and their amelioration still needed to be clarified. Vitamin C is an ideal antioxidant to increase tissue protection due to its easy, effective and safe dietary administration in large range of concentration without harmful side effects. To investigate through histological examination by light and electron microscope and morphometric study the effects of aspirin with or without ascorbic acid [Vitamin C] for 2 weeks on fundic mucosa of adult male albino rats. Twenty eight adult male albino rats were used and randomly divided into four equal groups: Control group; vitamin C group was given 200 mg/kg body weight; ASA group was given 100 mg/kg body weight of aspirin; the fourth group was given both vitamin C and aspirin. Animals treated daily for 2 weeks then sacrificed by cervical dislocation. Stomach tissues were excised for macroscopic, light and electron microscopic study and morphometric analysis. Oral administration of aspirin induced marked changes in gastric mucosa detected by both light and electron microscope ranging from simple hemorrhagic streaks to marked damage with severe erosions, exfoliation and presence of wide areas of epithelial discontinuity [ulcer formation]. This was accompanied by significant decrease in the count of lining cells except parietal cell count. Ulcer Index [UI], showed high significant increase. The addition of vitamin C significantly attenuated gastric damage and could protect gastric mucosa against the injurious effect of aspirin as evidenced from decreased UI and parietal cell count together with restoration of mucosal appearance. These results concluded that ASA combined with vitamin C in comparison with ASA induced less gastric mucosal damage and this protective effect might be due to the attenuation of oxidative stress and decreased count of parietal cells and consequently decrease of gastric acidity

Parasitological studies of the lizard, ludakia stellio in arish, north Sinai governorate, Egypt

In the lizard, Laudakia stellio, the gastrointestinal tract harboured four helminthic-parasites: two nematodes Spauligodon auziensis [Seurate, 1917] Paraparyngodon hulbosus [Linstow, 1 897], two larval stages of nematode, and one cestode, Oochoristica sp. [Kennedy et al., 1982]. The total infection rate of L. stellio was 93%. Out of 45 L. stellio examined, 42 were infected with number of parasites ranged from 0-72 and mean intensity 11.57. Parasites burden on their host populations was highly aggregated with k value was 0.01. No significant correlation was found between host weight and intensity of infection. The histopathological impact of infection was examined indicating the tissue reaction against the parasite at the site of attachment

Personal experience in posterior spinal fixation approach for patients with spinal tuberculosis

This study consisted of 20 consecutive patients of spinal tuberculosis treated in the period from January 1993 till October 1996. 12 patients were males and 8 were females. The age of presentation ranged from 34 to 72 years with mean age 46 years. The clinical presentation included persistent mid- or low back pain and tenderness in 20 patients, paraparesis in 9 and kyphosis in 12. All patients were treated by antituberculous chemotherapy together with posterior approach. The mean follow-up period was 24 months [range 12-36 months]. All patients showed clinical and radiological evidence of fusion. 7 patients had improvement in motor power and 12 in the angle of kyphosis. There was 91% initial correction and 79% final correction of kyphosis. With chemotherapy, posterior approach provide satisfactory results in selected patients of spinal tuberculosis to achieve treatment goals including correction and maintaining correction of spinal deformity

Antimicrobial susceptibility of bacterial isolates associated with chronic prostatitis

Fifty-three strains were isolated from expressed prostatic secretion of patients suffering from chronic prostatitis, microscopically and biochemically identified. About 89% of the 53 strains were Gram- positive cocci, whereas 11% were Gram-negative rods. The susceptibilities of the isolates to 16 different antimicrobial agents were assessed by the disc-sensitivity test. This investigation showed that afloxacin [quinolone] and carpenicillin [beta-lactam] could be used as drugs of choice in treatment of chronic prostatitis due to Gram-positive and Gram-negative bacteria. For chronic prostatitis due to Gram-positive bacteria, erythromycin would be the best
