Prolonged Survival of Pig Skin on Baboons After Administration of Pig Cells Expressing Human CD47

Evaluation of Protective Effects of Nano-formulated Silymarin Against UV Radiation on Guinea Pig Skin

  Background: As increased outdoor activities of people, they are more exposed to UV radiation, which causes harmful effects on skin. Silymarin has protective potentials against DNA damage and non-melanoma skin cancers, and also it has anti-oxidant, anti-inflammatory, and immune regulation characteristics. Nano formulation of plant material showed to be more effective than common ones.   Object...

Effects of Pentoxifylline on the healing of irradiated wounds in pig skin

Background: This study was designed to investigate the efficacy of Pentoxifylline (PTX) in the treatment of irradiated wounds. Materials and Methods: Ten female pigs of the Large White strain were used in these investigations. Six skin fields, 4 * 4 cm and separated from each other by 4 cm, were marked out on each flank and those on left flank were irradiated with 18Gy single dose of 250 kV X-r...

Karyotype of Hairless Guinea pig

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

Possible Relaxant Effects of Thymoquinone on Guinea Pig Tracheal Chain

In the previous studies the relaxant, anti-cholinergic (functional antagonism) and anti-histaminic effects of Nigella sativa have been demonstrated on guinea pig tracheal chains. To elucidate the main substance responsible for the relaxant effect of this plant, the effect of thymoquinone, one of the main constituent of Nigella sativa was examined in this study. The bronchodilatory effects of th...
