Abstract: Snake bite is a major health problem in developing countries. And the recent treatments have many limitations such as: efficiency, side effect and expenses. Designing new antivenom is base on generating a DNA plasmid containing the most immunogenic motifs of the venom toxins in order to generate antibodies to this plasmid; next it is injected to a camel, then the extracted antibodies used as antivenom. The aim of this study to compare between the venom gland and the gland transcriptomes, hoping that using the venom as a source of mRNA will avoid sacrificing the snake. In this study a compare between the vascular endothelial growth factor transcriptomes in venom and venom gland by obtain cDNA from the cDNA library then the cDNA in amplified by PCR followed by cloning it in TOPO plasmid in E.coli. Then the cloning product is sequenced and an alignment is made between the venom VEGF and venom gland VEGF and also other VEGF-F from different sources. Finally get the sequence bioinformatics. The result shows a 100%indindity between the venom and venom gland VEGF and the previously sequenced Bitis arietans VEGF. Which suggest that venom is an excellent source for the VEGF mRNA. But a further investigation should be done on the role of the VEGF in the envenoming process before including the VEGF motif the rationale therapy DNA plasmid.

. Introduction:

Snakes have from ancient time related to sciences associated with poison and death, such as toxicology plus as a symbol of medicine (Ramoutsaki 2000). Today 421, 000 people are affected by snake bite with greater than 20,000 deaths annually (Kasturiratne A 2008)

Essay on The Suprarenal Gland - The suprarenal gland (adrenal gland) is located at the top of each kidney; therefore each person has two adrenal glands. Adrenal glands appear to look like triangular shaped objects on top of the kidneys. The adrenal glands are dire in creating different hormones that are necessary for a fully functional body. With each adrenal gland, they are both made up of two different sections. The first section being the adrenal cortex, and that is located on the outer region of the adrenal gland; the second section called the adrenal medulla, and that is located in the inner region of the adrenal gland....   [tags: adrenal cortex, adrenal gland, cortisol]

Revealing Venom Complexity through Mass Spectrometry Essay - Introduction Venoms from animals have been known to be rich sources of bioactive molecules. They are highly specific and potent to certain ion channels, membranes and receptors, creating a huge potential in field of drug discovery (Escoubas et al. 2008; Bailey & Wilce 2001, Prashanth et al. 2012). Analytical tools have been crucial in uncovering the peptide libraries they contain (Escoubas et al. 2008, Prashanth et al. 2012) Venoms are highly complex, indicating the large amount of molecular species or components even from a single individual....   [tags: biochemistry, venoms from animals]

Thyrod Hormone and Gland Essay - Thyroid hormones are Tyrosine based hormones that require triidothyronine (T3) and Thyroxine (T4). These hormones are produced by the thyroid gland. The Thyroid gland is primarily known for the regulation of metabolism, as well as proper production of T3 and T4. Iodine is the main component that is needed. Dysfunction of Iodine can lead to decreased production of T3 and T4, resulting in enlarged thyroid tissue and even lead to thyroid diseases. In order for the thyroid hormone to function adequate amount of Thyroxine (T4) should be found within the blood....   [tags: Iodine, Metabolism] 850 words

The Biology of the Venom of Hapalochlaena Maculosa Essays - The Biology of the Venom of Hapalochlaena maculosa Hapalochlaena maculosa, commonly known as the blue-ringed octopus, is a golf ball-sized cephalopod inhabiting the waters around Tasmania and southeastern Australia with a highly potent neurotoxin that it uses as a predatory and defensive mechanism. H. maculosa does not actually synthesize its venom, but rather, the neurotoxin (known as maculotoxin) is produced by a bacterial symbiont of the octopus that lives in its salivary glands. While not overly aggressive, H....   [tags: Poisonous Australia Wildlife Essays]

Melatonin And The Pineal Gland Essays - Melatonin And The Pineal Gland Set deep in our brains is a tiny gland called the pineal gland. This tiny gland is in charge of the endocrine system, the glandular system that controls most of our bodily functions. The pineal runs our Œbody clocks', and it produces melatonin; the hormone that may prove to be the biggest medical discovery since penicilin, and the key to controlling the aging process. The pineal gland controls such functions as our sleeping cycle and the change of body temperature that we undergo with the changing seasons....   [tags: essays research papers fc]
