Acute ethanol administration (4 g/kg i.p.) induced a significant decrease of nitrosoguanidine-sensitive guanylate cyclase activity in mouse cerebellum. The enzyme activity was maximally attenuated 20 min after the administration and recovered to the initial level within 24 hr. When nitrosoguanidine-sensitive guanylate cyclase activity was assayed in the presence of thiols such as glutathione an...

Purpose: Aloe buettneri A. Berger is commonly used in Togolese folk medicine to treat inflammation and gastric ulcer. In this study we investigated the anti-oedema, analgesic, antipyretic and ulcer healing properties of the hydro-alcohol extract of their leaves. Methods: Rat oedema paw were induced by the injection of 0.1 ml of formaldehyde 1%, tail flick method is used to study analgesic prope...

PURPOSE To evaluate the feasibility and effectiveness of transcatheter embolization by forcible intraarterial injection of a mixture of ethylene vinyl alcohol copolymer (EVAL) and ethanol under microballoon occlusion compared with conventional transcatheter arterial embolization methods in nontumoral swine liver. MATERIALS AND METHODS Nine swine were divided into three groups: embolization wi...

A shadow moving overhead acts as a danger stimulus and elicits an escape response in the crab Chasmagnathus granulatus that habituates promptly and for a long period. The effect of acute ethanol treatment on this long-term memory was analyzed. A single injection of 0.01, 0.05, or 0.1 micrograms ethanol (ET)/g given 30 min before iterated presentation of a visual danger stimulus failed to affect...

BACKGROUND Postoperative bile duct leak following hepatobiliary and pancreatic surgery can be intractable, and the postoperative course can be prolonged. However, if the site of the leak is in the distal bile duct in the main biliary tract, the therapeutic options may be limited. Injection of absolute ethanol into the bile duct requires correct identification of the bile duct, and balloon occlu...

There is no consensus on how to establish models of osteonecrosis of the femoral head (ONFH) in large mammals. The aim of this study was to investigate the effectiveness of a novel canine model of ONFH, induced by a navigated injection of absolute ethanol. Using three-dimensional reconstruction and rapid prototyping manufacturing techniques, a new template was designed and processed to navigate...

BACKGROUND: Autonomous thyroid nodules can be treated by a variety of methods. We assessed the efficacy of percutaneous ethanol injection in treating autonomous thyroid nodules. METHODS: 35 patients diagnosed by technetium-99 scanning with hyperfunctioning nodules and suppressed sensitive TSH (sTSH) were given sterile ethanol injections under ultrasound guidance. 29 patients had clinical and bi...

AIMS Studies have shown that the impairing effects of Delta-9-tetrahydrocannabinol (THC) are dose-related. Cannabis intake increases the risk of traffic accidents. The purpose of this study was to see how different clinical tests and observations were related to blood THC concentrations and to determine whether the combined influence of THC and ethanol was different from either drug alone. DE...

Ethanol abuse during adolescence may significantly alter development of the prefrontal cortex which continues to undergo structural remodeling into adulthood. Glutamatergic neurotransmission plays an important role during these brain maturation processes and is modulated by ethanol. In this study, we investigated glutamate dynamics in the medial prefrontal cortex of freely moving rats, using en...

Percutaneous ethanol injection therapy (PEIT) has been administered as a safe therapeutic modality for patients with small hepatocellular carcinoma (HCC). Due to the nature of the straight approaching line of a PEIT or radiofrequency ablation needle, penetrating the vessels that are interposed between the dermal insertion point and the nodule is unavoidable. A device with an overcoat needle and...
