Rat thalamocortical slices maintain synoptic connections between thalamus and cortex. When perfused with low Mg++-ACSF, thalamocortical slices exhibited two main types of spontaneous bursting activity. One is monotonic burst of 3-15 Hz and another is multiphasic bursts which have a tonic burst firing period and a late phase of clonic burst firing. These bursts are similar in frequency and during to EEG recordings from human generalized seizures. Exploiting the advantages of in vitro preparations, the electrophysiological action of taurine were studied. Exogeneous application of taurine profoundly decreased spontaneous bursting activities, which it caused only slight reduction of electrically evoked response in cortical layer. Taurine-induced current was blocked by 40 uM bicuculline, GABA receptor antagonist, in acutely isolated coritcal neurons. These results suggest that endogeneous taurine may regulate the hyperexcitablility through GABAa receptor.

Augmentation cystoplasty is effective in the rehabilitation of the contracted bladder of small capacity caused by tuberculosis or interstitial cystitis refractory to more conservative methods of management. Genitourinary tuberculosis is the most common cause of contracted bladder in Korea and it may lead to considerable vesicoureteral reflux and progressive deterioration of renal function. The use of hemi-Kock ileal pouch with an afferent intussuscepted nipple is a suitable solution in patient in whom the bladder outflow tract provides adequate resistance and supratrigonal cystectomy is to be performed with construction of an antireflux mechanism. Herein, we report 4 cases of hemi-Kock ileocystoplasty.

Inflammatory mediators, such as oxidants, TNF-alpha, and IL-6, play a major role in the systemic response to bum injury It has been known that a continuing inflammatory response cause a sepsis and subsequent multiple organ failure. Recent studies have shown that burn patients receiving recombinant human growth hormone(rhGH) therapy have an improvement of the general condition, but the mechanism by which rhGH exerts its effects has not been clearly understood. The aim of this study was to evaluate the effect of rhGH on the early bum injury. Female Sprague-Dawley rats were divided into four groups : control group, bum group, burn plus rhGH treated group, and rhGH only treated group. Animals were killed at 30min., 3, 6, 24, and 48 hours after treatment. Histology and biochemical changes including malondialdehyde(MDA) content, tissue reduced glutathione(GSH) and catalase activity in the lung and liver, and plasma TNF-alpha and IL-6 levels were examined. Lung histology in the bum plus rhGH treated group showed decreased inflammtory response such as neutrophil and lymphocyte infiltrations, interstitial thickening, and edema compared with the bum group. Liver histology in the bum group revealed mild neutrophil and lymphocyte infiltrations, vacuolization .of hepatocytes, disrupted lobular structures, and dilated sinusoids. But liver histology of the bum plus rhGH was similar to control group. Lung and liver MDA in the burn plus rhGH and rhGH only treated groups were decreased with time compared with the burn group. Lung and liver GSH and catalase activities in the bum plus rhGH and GH only treated groups remained significantly increased compared with the bum group for the 48-hours period. Plasma TNF-alpha levels in the bum group remained elevated for the 48-hours period compared with the bum plus rhGH and rhGH only treated groups. Plasma IL-6 levels in the burn group were significantly increased only at first compared with the bum plus rhGH and rhGH only treated groups. These results suggested that rhGH showed inhibitory effects on the inflammatory cell infiltration and lipid peroxidation in the lung and liver after bum injury. Increased GSH levels and catalase activities seemed to be associated with the antioxidant effect of rhGH. But the inhibitory effect of rhGH on plasma TNF- and R-6 levels was not clearly demonstrated.

BACKGROUND AND OBJECTIVES: The aim of this study was to determine the effect of ethanol on the regulation of vascular tone. MATERIAL AND METHODS: Using rat aorta ring, isometric contraction and 45Ca uptake were measured. Phorbol 12,13-dibutyrate (PDBu), phenylephrine, KCl were used for the regulation of smooth muscle tone. RESULTS: Ethanol induced transient contraction in rat aorta ring by dose-dependent manner. Ethanol suppressed the dose dependent contractile responses of vascular strip by phenylephrine, KCl and PDBu. Endothelium-dependent relaxation by acetylcholine was inhibited by ethanol. Ethanol depressed 45Ca uptake by high KCl but not by phenylephrine or PDBu in rat aorta. n-butanol selectively suppressed tonic contraction by high KCl, but t-butanol did not at the same concentration of butanol in rat aorta. PDBu-induced contraction was selectively suppressed by n-butanol but not by t-butanol. CONCLUSIONS: These findings suggest that the action of ethanol on phospholipase D is involved in the decreased response of rat aorta strip by vasoconstrictors.
