Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the present book, larval stages of the Egyptian toad Bufo regularis (Bufonidae) were used. Three groups of newly fertilized eggs were analyzed. One group was irradiated with ultraviolet (i.e, haploid), the second was heat- shocked (i.e, triploid) and the third one was used as control (i.e, diploid). Transverse sections of diploid, haploid and triploid embryos at different embryonic stages were used to study the distribution of melano-macrophage centres (MMCs). The pigment cells and MMCs were detected using the light microscopical study in the liver, kidney and spleen of the three tested group of B. regularis tadpoles. Moreover, the electron microscopical study of the MMCs in liver, kidney and spleen at different embryonic stages of B. regularis were also characterized. On the other hand, by using a highly sensitive reverse transcription- polymerase chain reaction (RT-PCR) assay detected tyrosinase mRNA in liver and spleen of three tested group of B. regularis tadpoles; therefore the liver and spleen pigment cells (KCs) are able to synthesize melanin. mRNA tyrosinase not expressed in kidney;so the pigment cells of kidney are melanin- phagocytosing macrophage. 104 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present book aimed to evaluate the teratogenic effects of the Mucophylline is daily oral administered to the pregnant albino rats. The pregnant animals treated during the gestational period (5th - 19th day of gestation) with doses 30.83 mg/Kg and 66.61 mg/Kg. On the 20th day of gestation, the animals were sacrificed and the numbers of implanation sites, resorbed and live fetuses were counted. The placental weight, fetal weight, length and tail length were recorded. The external morphology and skeletal malformations, histological studies of maternal and fetal tissues were evaluated. Also the oxidative stress markers were evaluated. Results showed decreased weight gain, fetal growth retardation during gestation period was dose dependent. Hematoma and anomalies of limbs were detected morphologically. Fetal skeletal abnormalities included lack of bones ossification and bent ribs. In addition, the mucophylline induced histopathological changes in maternal and fetal tissues. Mucophylline caused oxidative stress by elevation of malonndialdehyde content, decrease in the activity of the antioxidant enzymes. All of these support and proof the teratogenic effect of the mucophylline. 360 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -En el presente libro, se utilizaron estadios larvarios del sapo egipcio Bufo regularis (Bufonidae). Se analizaron tres grupos de huevos recién fertilizados. Un grupo fue irradiado con luz ultravioleta (es decir, haploide), el segundo fue sometido a choque térmico (es decir, triploide) y el tercero se utilizó como control (es decir, diploide). Se utilizaron secciones transversales de embriones diploides, haploides y triploides en diferentes etapas embrionarias para estudiar la distribución de los centros de melanomacrófagos (CMM). Las células pigmentarias y los CMM se detectaron mediante el estudio microscópico de luz en el hígado, el riñón y el bazo de los tres grupos de renacuajos de B. regularis analizados. Además, también se caracterizó el estudio microscópico electrónico de los MMC en el hígado, el riñón y el bazo en diferentes etapas embrionarias de B. regularis. Por otro lado, mediante el uso de un ensayo de reacción en cadena de la polimerasa con transcripción inversa (RT-PCR) de alta sensibilidad, se detectó el ARNm de la tirosinasa en el hígado y el bazo de tres grupos de renacuajos de B. regularis analizados; por lo tanto, las células pigmentarias (CP) del hígado y el bazo son capaces de sintetizar melanina. El ARNm de la tirosinasa no se expresa en el riñón; por lo tanto, las células pigmentarias del riñón son macrófagos fagocitantes de melanina.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 92 pp. Spanisch.
