Abstract
Excessive alcohol consumption can have serious negative consequences on health, including addiction, liver damage, and other long-term effects. The causes of hangovers include dehydration, alcohol and alcohol metabolite toxicity, and nutrient deficiency due to absorption disorders. Additionally, alcohol consumption can slow reaction times, making it more difficult to rapidly respond to situations that require quick thinking. When consuming a large amount of alcohol, it takes a longer time to recover the righting reflex and balance following ethanol exposure. This study aimed to evaluate the potential of lactic acid bacteria (LAB) to alleviate alcohol-induced effects and behavioral responses. The two LAB strains isolated from kimchi, Levilactobacillus brevis WiKim0168 and Leuconostoc mesenteroides WiKim0172, were selected for their ethanol tolerance and potential to alleviate hangover symptoms. Enzyme activity assays for alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) were conducted to evaluate the role of these bacteria in alcohol metabolism. Through in vitro and in vivo studies, these strains were assessed for their ability to reduce blood alcohol concentrations and to protect against alcohol-induced liver damage. Results indicated that these LAB strains exhibited significant ethanol tolerance and elevate ADH and ALDH activities. LAB administration remarkedly reduced blood alcohol levels in rats with excessive alcohol consumption. Moreover, the LAB strains showed hepatoprotective effects and enhanced behavioral outcomes, highlighting their potential as probiotics for counteracting the adverse effects of alcohol consumption. These findings support the development of functional foods incorporating LAB strains that can mediate behavioral improvements following alcohol intake.

Abstract
Chronic allograft nephropathy (CAN) includes pathologic changes of interstitial fibrosis, tubular atrophy, and fibrous intimal thickening. Transforming growth factor (TGF)-beta1 is a fibrogenic cytokine involved in renal allograft fibrosis. Hypoxia-inducible factor (HIF)-1alpha is induced as an adaptive response to hypoxia triggering the production of fibrogenic cytokines such as TGF-beta1. Between January 1995 and February 2005, we performed 71 renal allograft biopsies in 61 recipients. Immunohistochemical studies were performed with an immunoperoxidase technique using as the primary antibody either a rabbit anti-human TGF-beta1 polyclonal or a mouse anti-human HIF-1alpha monoclonal reagent. The glomerular TGF-beta1 expression in recipients diagnosed with glomerulonephritis was significantly greater than other pathologic groups (P < .05), and the glomerular TGF-beta1 expression in the heavy proteinuria group (> or =2.5 g/d) was significantly greater than the low proteinuria group (<1.0 g/d; P < .05). The tubular and interstitial TGF-beta1 and HIF-1alpha expressions in CAN were greater than in other groups (P < .05). The tubular TGF-beta1 expression among the graft loss group was significantly greater than the graft function group (P < .05).

Abstract
OBJECTIVE In dealing with cases of oedematous brain, relaxation during the transsylvian approach to supratentorial aneurysms has been accomplished by ventricular drainage by using the anatomic point defined by Dr. Paine. However, we have experienced patient complications when using this point. We propose a novel anatomic point to reduce catheter-related complications and facilitate adequate ventricular puncture during ruptured aneurysm operations. METHODS Ten patients underwent aneurysmal neck clipping for ruptured aneurysm by means of the transsylvian approach. The use of a novel anatomic point for intraoperative drainage was examined using a neuronavigation system. RESULTS Using the novel point of entry for ventricular cannulation proved to be reliable for puncture and reduced chance of malpositioning. CONCLUSION Secure intraoperative ventricular cannulation is reliably achieved by pointing the catheter approximately 2 cm beyond a line extending from the anterior limb of the triangle described by Paine. This technique reduces injury to the deep brain and enhances preciseness and safety of ventricular cannulation.

Abstract
We have monitored mitogen-stimulated mouse splenocyte proliferation as a biological end point of radiation damages to access adaptive response to ionizing radiation. When cells were pre-exposed to an adapting dose of 0. 01 Gy of low dose gamma-ray 4, 7, and 20 hours prior to an acute challenging dose of 2 Gy, most significant enhancement in splenocyte proliferation was induced at 4 hour interval. When the challenging high dose was varied, an adaptive response was observed at up to 4 Gy of high dose gamma-ray challenge. Gamma-ray-irradiated mouse splenocyte showed characteristic morphology of apoptotic cells. The extent of DNA fragmentation, another characteristic of apoptotic cells, was also reduced in low dose gamma-ray-adapted cells. The addition of protein or RNA synthesis inhibitor, cycloheximide or 5,6-dichloro-1-beta-d-ribofuranosylbenzimidazol (DRFB), respectively during adaptation period, the period between low and high dose irradiations, were able to inhibit the induction of adaptive response. These data suggest that to induce adaptive response to ionizing radiation in mouse splenocytes, both protein and RNA synthesis are required.
