The morphological effects of two snake venoms, N. naja and A. piscivorus, and of the Direct Lytic Factor and Phospholipase-A, compounds purified from N. naja crude venom, were investigated on lung and cremaster vessels of rats. The microcirculation of the rat reacts to these two venoms differently:

Nigexine is a basic phospholipase A2 from the venom of the spitting cobra Naja nigricollis. In addition to its anticoagulant and cytolytic properties, nigexine also affects neuromuscular transmission in vitro. On chick biventer cervicis preparations, 1.5 microM nigexine caused a slowly developing

A case of snakebite, thought to be due to a Cape cobra, in a young girl is described. Unusual features were a protracted period of paralysis and severe neurological residua in the form of hemiparesis and impaired vision. The ophthalmological features started as a bilateral optic neuritis and

The course of degeneration and regeneration of mouse skin following intradermal injection of spitting cobra (N. nigricollis) venom was investigated using simple histological staining techniques. Early changes observed were vascular congestion, oedema and degeneration of the skeletal muscle cell

The aim of this study was to evaluate the effect of venom from Naja naja karachiensis on platelet-poor plasma, activated partial thromboplastin time (aPTT), prothrombin time (PT) / international normalized ratio (INR), thrombin time (TT) and to evaluate its effect on clotting time upon storage of

Telomeres comprise tandem repeated DNA sequences that protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes, and their lengths might vary with sex and age. Here, age- and sex-related telomere lengths in male and female captive Siamese cobras (Naja kaouthia)

OBJECTIVE To investigate the therapeutic effects of a nerve growth factor (NGF) isolated and purified from the venom of Naja naja atra on injured sciatic nerves in adult cat. METHODS Model of sciatic nerve crush lesion in 20 cats was made. After the operation, in the therapeutic group, NGF(2

In the present experiment 164 pregnant white Wistar rats were used to study the effect of Naja haje (Egyptian cobra) venom on the developing kidney. The rats were divided into 3 groups; a control group, a group receiving one LD50 of N. haje venom and the third injected with 1/8 of LD50. The

Gradients in phosphorus (P) removal and storage were investigated over 6 years using mesocosms (each consisting of three tanks in series) containing submerged aquatic vegetation (SAV) grown on muck and limerock (LR) substrates. Mean inflow total P concentrations (TP) of 32 μg L(-1) were reduced to
