In this article which was published in Cell J, Vol 16, No 2, Summer 2014, on pages 111-116, the title of table 3 was published incorrectly as: "Sperms concentration, vitality, survival and morphology in Zanjani VIPER, (mean ± SD) ". The correct one is "Sperm motility rate in three different parts of vas deferns duct in Zanjani VIPER".

Objective: Zanjani VIPER (VIPERa albicornuta) is an endemic venomous snake in East Azerbaijan Province, Iran which is medically important due to its application for antivenin production in the laboratory. We need to produce this snake in captivity. This study was conducted to characterize mature male Zanjani VIPER and to evaluate its sperm reproductive parameters.Materials and Methods: This applied- descriptive study was conducted on twenty Zanjani VIPER samples collected from Ag Dag Mountain in East Azarbaijan Province, Iran, between September and October 2010. After the snakes were anesthetized and sacrificed humanly, their morphometric specifications and sperm reproductive parameters, including concentration, motility, vitality, morphology, and survival time, were measured.Results: Morphometric specifications and evaluation of sperms of the snake showed the following information: Zanjani male VIPER, body length of 73.65±4.35 cm, tail length of 5.465±0.48 cm, and mature snakes with testicular volumes of 0.61±0.81 ml (right) and of 0.46±0.17 ml (left). Our findings revealed average sperm concentration of 0.47±0.1´106 ml-1, motility of 49-55 %, vitality of 46.11±9.63 %, normal morphology of 61.71±5.3%, and survival time of 6±2 hours at the laboratory temperature. Statistical analyses were performed using Student’s t test for comparison of two values, and one-way ANOVA was applied where three values were compared.Conclusion: Results suggest that mature Zanjani male VIPER with mature sperms in its vas deferens is present in late summer and early autumn seasons in Bostanabad County, Iran.

The venom of the VIPER is very important in pharmaceutical usage, such as in the process of coagulation during medical care. This study aims to evaluate the coagulant factor of Latifi and Zanjani VIPER venom. In the current study, after electrophoresis of proteins found in VIPER venom, all of the thick and strong bands of proteins were isolated and prepared for examination of coagulation characteristics, like pro-thrombin time (PTT) and active partial thromboplastic time (APTT), followed by further study by mass spectroscopy. In this way, 11 bands of proteins were recognized in sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). After PT and APTT tests, one common band in 26 KDa could lead to coagulation of blood plasma in less than one second. Mass spectroscopy identified this band as serine protease isoform4. The results confirmed the coagulation effect of a 26 KDa protein fraction of venom from Latifi and Zanjani VIPERs.

Habitat is an important component of biodiversity conservation. Understanding the habitat characteristics to achieve conservation programs is inevitable. The present study was carried out with an aim to identifying microhabitat ecological factors effecting habitat use of Iranian Mountain Steppe VIPER (VIPERa ebneri) in Alborz Mountains. Sampling was carried out during spring and summer in 2012-2013. Ecological variables were measured in 31 presence and 33 absence plots of 12 ´ 12 m. Results of binary logistic regression analysis showed that hillsides with dense vegetation cover and decimetric stones at the appropriate distance from water sources, are the most important variables in habitat suitability of Iranian Mountain Steppe VIPER in the area. The results of this study can fascilitate effective conservation of the remainig populations of Iranian Mountain Steppe VIPER through determining factors limiting the distribution of this species as well as identifying and protecting its critical habitats.

Inroduction & Objective: According to need to preserve the native breed snakes, in order to use humanitarian and environmental terms, In 2008, the environmental protection in vulnerable categories of the Red List Department of Environment (IUCN) (14),and serpents Zanjani is required for the survival of the species reproductive parameters noted.Material and Methods: For this purpose to study the reproductive parameters of Zanjani VIPER(Iran), microscopic and macroscopic level: Check the male reproductive tract, sperm vas channel concentration, motility and morphology, weight, testicular volume, the evaluation of spermatogenic cells in the tubules and measuring weight and body length, tail length is studied. VIPER Zanjani ring of 11 males in the winter of 2011 Bostanabad area in East Azerbaijan, which is mountainous and cold climate, samples were taken.Results: The results showed that the mean maximum body weight of 248.33 ± 32.81 g, body length 76.41 ± 4.12 cm in February, tail length 4.87 ± 0.62 inches in February and maximum size of the right testis 666.13 ± 110.58 cubic millimeter of the Month for February and left 667.52 ± 189.08 cubic millimeter was seen in March. The highest average length of the left and right channels, respectively, 19.5 and 16.66 ± 2.54 cm was corresponding to the months of January and February. Maximum average sperm concentration in February 15´104/ml, morphology January %88.61±12.18 normal sperm motility and the highest 33.79 ± 22.91 of March the motility of the proximal to the distal face was increased.Conclusion: According to the findings VIPER Zanjani male reproductive tract morphology, including three in the proximal, median and distal to the That looks like a pit VIPER, Crotalus durissus terrificus species of the temperate zone of south-eastern Brazil is and the rate of sperm production in the months of February and March may be due to the mating stage (autumn) is.
