With respect to radiation damage to humans, it is important to seek possible radioprotectants to modify the normal response of biological systems to radiation-induced toxicity or lethality. For this reasons, the search for less-toxic radiation radioprotectants has spurred interest in the development of different compounds. The radioprotective effects of citrus extract were investigated by using...

In this study, for the first time in Iran, the karyotype of bigmouth Lotak, Cyprinion macrostomum Heckel, 1843, was investigated through examining metaphase chromosomes of seven fish with mean weight 30±5g caught by electrofishing from Godarkhosh River in Ilam Province. To stimulate cell divisions, fish were injected intraperitoneally two times by phytohemagglutinin (PHA). The cell divisions we...

The effects of severe protein malnutrition (4%) on myenteric neurons of Wistar rat duodenum, in relation to a standard 22%-protein diet for rodents, were assessed in this study. Segments of the duodenum from 10 rats from each nutritional group were submitted to the elaboration of whole mounts - 5 stained with Giemsa to determine the total population of myenteric neurons and the others stained b...

This paper investigates the possibility of computerised diagnosis of malaria and describes a method to detect malaria parasites (Plasmodium spp) in images acquired from Giemsa-stained peripheral blood samples under conventional light microscopes. Prior to processing, the images are transformed to match a reference image colour characteristics. The parasite detector utilises a Bayesian pixel cla...

The effects of protein malnutrition on the quantitative aspects of the myenteric plexus in the ileum of adult Rattus norvegicus were assessed. Thirty 90-day-old rats were divided into two groups: Control Group (CG, n=15) and Experimental Group (EG, n=15). The CG received 26% protein chow and the EG received 4% protein chow for 90 days. At the end of the experiment, the animals from the CG weigh...

Lizardfish is one of the economically important fishes of Persian Gulf. In recent years, white, ellipsoid, round or elongated nodules were found in body cavity of this fish species which in preliminary microscopic examination were recognized as microsporidia. To determine the approximate prevalence rate of microsporidian infection and to establish its taxonomic position, 50 lizardfish were boug...
