Chemical Peeling and Microdermabrasion of the Skin:Comparative Immuno-histological and Ultrastructural Studies

2008 | Keywords peeling, microderm abrasion, , skin,
Chemical Peeling and Microdermabrasion of the Skin:Comparative Immuno-histological and Ultrastructural Studies
Comparative immunohistological and ultrastructural studies were performed on specimens taken before and after the application of chemical peels (Jessner’s solution and glycolic acid) and microdermabrasion to the clinically normal facial skin of the post-auricular region. Skin treated with chemical peels showed the immunohistological features of wound healing. Beside these, ultrastructural changes of cell injury were observed. These morphological changes were ...

Histological Changes in Some Parenchymatous Organs of the Rat due to Scorpion Envenoming and the Role of the Antivenin in Abolishing these Changes

Histological Changes in Some Parenchymatous Organs of the Rat due to Scorpion Envenoming and the Role of the Antivenin in Abolishing these Changes
BACKGROUND:. Scorpions are arthropods belonging to class arachnida. The value of antivenom was never questioned following snake bites, but opinions differ in case of scorpion stings. OBJECTIVES: To investigate the effectiveness of scorpion antivenom in preventing or abolishing the histopathological changes occurring in the parenchymatous organs following experimental scorpion envenoming. METHODS: Forty five male Albino rats were divided into nine ... Read more

Ultrastructural study of the effect of the ink fluid of the sea hare Aplysia Dactylomela on the hepatocytes and kidney tubules of Mice

2007 | Keywords Ink fluid, sea hare, Red Sea,
Ultrastructural study of the effect of the ink fluid of the sea hare Aplysia Dactylomela on the hepatocytes and kidney tubules of Mice
Sea hares are a group of marine molluscs which possess many ways for defense including the chemical defense. The hares produce ink fluid from the ink gland to escape and protect themselves from their enemies. The ink gland of sea hares secrete, the ink fluid which contains many bioactive factors acting against potential enemies with toxic activities. _Aplysia dactylomela_ is ... Read more

The Effect of Glucocorticoid Therapy on the Inflammatory and Denderetic Cells in Muscular Dystrophies

The Effect of Glucocorticoid Therapy on the Inflammatory and Denderetic Cells in Muscular Dystrophies
Various clinical trials have documented the therapeutic benefit of glucocorticoids (GCs) in enhancing muscle strength and slowing disease progression of Duchenne and Becker muscular dystrophies (DMD/BMD). We hypothesized that GCs may have relevance to the differential anti-inflammatory effect on mononuclear inflammatory cells (MICs) and Dendritic cells (DCs) infiltrating the dystrophic muscles. In this prospective study, two muscle biopsies were obtained ... Read more

Morphological Evaluation of the Radio protective Effects of Melatonin Against X-Ray Induced Early and Acute Testes Damage in Albino Rat: an Animal Model

Morphological Evaluation of the Radio protective Effects of Melatonin Against X-Ray Induced Early and Acute Testes Damage in Albino Rat: an Animal Model
Irradiation has profound effects on the reproductive function. Our knowledge about radioprotective effects of melatonin against X-ray-induced testis damage is rudimentary. In this investigation, we hypothesized that melatonin can minimize germ-cell depletion and morphological features of cell damage in testis following X-ray irradiation (XRI). To examine these effects, and to test our hypothesis, an animal model comprised of 60 Albino ... Read more

: Melatonin and Roentgen Irradiation of the Testes. .
Melatonin is a free-radical scavenger and antioxidant. Roentgen irradiation of testis (animal model formed of albino rats) was associated with destruction and depletion of the germinal epithelial cells. In roentgen-irradiated, melatonin-pretreated animals, these changes were markedly ameliorated. Thus administration of melatonin before irradiation can protect testis from some of the destructive effects of roentgen irradiation. Read more

Phenotypic Characterization of The Immune And Mast Cell Infiltrates In The Human Testis Shows Normal And Abnormal Spermatogenesis

Phenotypic Characterization of The Immune And Mast Cell Infiltrates In The Human Testis Shows Normal And Abnormal Spermatogenesis
OBJECTIVE: To assess the types, distributions, and numbers of immune cell infiltrates in the testes of men with azoospermia. DESIGN: Prospective study. SETTING: University research and clinical institutes. PATIENT(S): Thirty-one men with azoospermia showing normal spermatogenesis (n = 10), germ cell maturation arrest (GA, n = 12), and Sertoli cell-only syndrome (SCO, n = 9). INTERVENTION(S): Testicular tissue biopsies. Sections ... Read more

Quantitative Comparison of Infected Schistosomiasis Mansoni and Haematobium:Animal Model Analysis of the Granuloma Cell Population

Quantitative Comparison of Infected Schistosomiasis Mansoni and Haematobium:Animal Model Analysis of the Granuloma Cell Population
To evaluate the hypothesis that the granuloma cell population in S. haematobium is different from that of S. mansoni infections, a hamaster animal model was established. Infection of hamesters was induced by abdominal skin exposure of male golden hamsters with 300 cercariae. S. haematobium granuloma cell population in the small intestine, urinary bladder, liver and spleen and those of S. ... Read more

Ultra structural Evaluation of the Radio protective Effects of Melatonin Against X-Ray Induced Skin Damage in Male Albino Rats

2005 | Keywords X-ray irradia, melatonin, skin,
Ultra structural Evaluation of the Radio protective Effects of Melatonin Against X-Ray Induced Skin Damage in Male Albino Rats
Our knowledge about the radioprotective effects of melatonin against X-ray-induced skin damage is still lacking. To examine these effects, an animal model of 60 Albino rats was used. The animals were divided into five groups: Group 1, nonirradiated; Group 2, X-ray irradiated (XRI, 8 Gy); Group 3, XRI pretreated with solvent (ethanol and phosphate-buffered saline); Group 4, nonirradiated group treated ...

Augmentation of age-related changes in somatotrophs after long term pinealectomy

Augmentation of age-related changes in somatotrophs after long term pinealectomy
The relationship between growth hormone producing cells in the pars distalis of the pituitary gland (somatotrophs) and the pineal gland function in rats is nearly not elucidated, particularly in the aspect of melatonin participation. The current study tested whether the life-long reduction of endogenous melatonin levels due to pinealcctomy would.influence the morphological and the ultra structural changes of somatotrophs as ...
