Lipoma involving brain and spinal cord is a rare tumor that most commonly located in the midsagittal region. This lesion is usually asymptomatic and has been reported incidentally at postmortem examination. Recently, the CT scan establishes the diagnosis of intracranial lipoma on the basis of typical X-ray absorption and location. The authors experienced a case of intracranial lipoma of occipital lobes. The patient was 7 months-old male who had protruding mass on the occipital region after birth. The mass revealed an uncapsulated lipoma with foca cartilage formation. We report this case with brief review of literatures.

This study was undertaken to compare the effects of furosemide on the serum concentration of sodium and osmolality after transurethral prostatic resection(TURP) using cytal solution, and to determine the adequate time of administration of frurosemide. At the end of prostatic resection, 15 patients were allocated randomly to receive furosemide (furosemide group) and were compared with 15 patients without administration of furosemide (control group). There was no difference in mean serum concentation of sodium between two groups. Serum osmolality in furosemide group was significantly increased as compared with control group one hour after operation. So cytal solution used during staged TURP and short operation within one hour do not affect serum corcentration of sodium and administration of furosemide is not associated with a change in serum concentration of sodium. But furosemide meaningfully increases the serum osmolality and it is more effective to administer it with administration at the end of prostatic reseetion.

Thirteen patients with visceroatrial situs abnormalities were evaluated by magnetic resonance(MR) imaging. Eleven patients were confirmed surgically. Two patitnts were diagnosed by MRI and cardiac catheterization. Right isomerism was found in seven patients, left isomerism in two, and situs inversus in four. For the determination of situs, we evaluated the morphology of atrial appendages and main bronchi, the relationship between abdominal aorta and inferior vena cava(IVC), and the status of upper abdominal viscera. The bilateral atrial morphology was differentiated in 8 of 12 patients. The bronchial situs was determined in 11 of 12 patients. Juxtaposition of abdominal aorta and IVC was found in 6 of 7 with right isomerism. IVC interruption with azygos continuation was found in all two with left isomerism. Incidentally three cases of short pancreas were found. MR imaging showed all structures relevant for the assessment of situs, thus obvrating the need for performing additional diagnostic procedures. MR imaging, therefore, is a valuable tool in the clinical management of patients who are suspected of having a situs abnormality.

Systolic time intervals were studied in a total of 83 patients with pure or predominant isolated valvular heart disease. They consisted of three groups of patients : namely, 38 cases of mitral stenosis, 25 cases of mitral regurgitation and 20 cases of aortic regurgitation. The mean of the electromechanical systole was within normal ranges in all three groups, and threre was no significant difference between the groups. The mean of the left ventriclar ejection time was also within normal limits in all groups, as was that of the electromechanical systole, but it was significantly shorter in patients with mitral regurgitation than in the others, and was significantly longer in patients with aortic regurgitation. The mean of the pre-ejection period and the ratio of the pre-ejection period to the left ventricular ejection time were within normal ranges in patients with aortic regurgitation, whereas both parameters were significantly increased in patients with mitral stenosis or mitral regurgitation, particularly in the latter.

Serial neurosonographic examinations are routinely performed at frequent intervals during nursery course of all preterm infants of very low-birth-weight who are admitted to the intensive care nursery of Presbyterian Medical Center from November 1, 1990 to July 30, 1992. After discharge, the following survivors who had received periodic, serial scanning by meas of cranial ultrasonography were longitudinally observed in an interdisciplinary neurodevelopmental follow-up program to a mean corrected age of 13 months. Neurodevelopmental outcome was assessed by means of Vojta's postural reaction and other neurological examinations. The results are as follows: 1) The incidence of PV-IVH in the study was 79%. 2) According to Papile's grading system of PV-IVH, gradel was 20%, gradell was 46%, gradelll was 19%, and grade IV was 13%. 3) The risk factors associated with PV-IVH were birth weight, gestational age, apgar score, ventilator care, RDS, and sepsis. 4) The mortality of PV-IVH was 20% for gradel, 19% for gradell, 44% for gradelll, and 67% for grade lV. 5) According to relationship between PV-IVH and neurodevelopmental outcome, in two of the four subjects with grade lll PV-IVH, moderate/severe CCD was developed. 6) According to relationship between PVE with cysts and nuerodevelopmental outcome, moderate/severe PVE with periventricular cysts larger than 3mm in diameter was associated with development of severe CCD.

6.Is Conventional Angiography Always Superior to MR Angiography in Evaluatin of Cerebral Aneurysm?.

Conventional angiography still remains the procedure of choice in evaluation of cerebral aneurysm. However, MRI and MR angiography can play different roles in vizualizing cerebral aneurysm. A 43-year-old male was evaluated for recurrent seizure attacks. The brain MRI showed non-enhancing iso-signal mass on T1WI, signal voiding mass with stalk-like structure on coronal T2WI in the right temporal region. MRA also revealed dark round signal. However, the conventional cerebral angiography failed to visualize it. Finally, the mass was confirmed as a huge aneurysm filled with intraluminal thrombus on operation. It should seem that contrast media could not fill the aneurysmal sac because of intraluminal thrombus in conventional angiography. But aneurysmal sac seemed to be visible on MRA as paramagnetic artifact of thrombus. So, it can be assumed that MRA is superior to the conventional angiography in some cases of cerebral aneurysm, especially when it is associated with intraluminal thrombus.

Background:
Hepatic steatosis, which involves the excessive accumulation of lipid droplets in hepatocytes, presents a significant global health concern due to its association with obesity and metabolic disorders. Inflammation plays a crucial role in the progression of hepatic steatosis; however, the precise molecular mechanisms responsible for this process remain unknown.
Methods:
This study investigated the involvement of the nucleotide-binding oligomerization domain-like receptor pyrin domain-containing-3 (NLRP3) inflammasome and the forkhead box O6 (FoxO6) transcription factor in the pathogenesis of hepatic steatosis. We monitored the NLRP3 inflammasome and lipogenesis in mice overexpressing the constitutively active (CA)-FoxO6 allele and FoxO6-null mice. In an in vitro study, we administered palmitate to liver cells overexpressing CA-FoxO6 and measured changes in lipid metabolism.
Results:
We administered palmitate treatment to clarify the mechanisms through which FoxO6 activates cytokine interleukin (IL)-1β through the NLRP3 inflammasome. The initial experiments revealed that dephosphorylation led to palmitate-induced FoxO6 transcriptional activity. Further palmitate experiments showed increased expression of IL-1β and the hepatic NLRP3 inflammasome complex, including adaptor protein apoptotic speck protein containing a caspase recruitment domain (ASC) and pro-caspase-1. Furthermore, thioredoxin-interacting protein (TXNIP), a key regulator of cellular redox conditions upstream of the NLRP3 inflammasome, was induced by FoxO6 in the liver and HepG2 cells.
Conclusion
The findings of this study shed light on the molecular mechanisms underpinning the FoxO6-NLRP3 inflammasome axis in promoting inflammation and lipid accumulation in the liver.

10.Two Cases of Mycotic Aneurysm with Intracerebral Hematoma.
Jong Sik SUCK ; Jung Shick KIM ; Dae Hi HAN ; Bo Sung SIM
Journal of Korean Neurosurgical Society 1977;6(2):499-506
Mycotic aneurysms are produced by an infected embolus from vegetations on the heart valves in bacterial endocarditis, which breaks off and lodges in the cerebral blood vessels. The wall of the embolized vessel becomes infected, invasion by inflammatory cells and necrosis of the wall are often followed by rupture and formation of a aneurysmal sac. These aneurysms are very are in incidence and are usually located more peripherally in the vascular tree than berry aneurysms, are more irregular in shape and are not necessarily located at bifurcations. Recently we experienced a case of mycotic aneurysm with intracerebral hematoma which had developed in a subacute bacteria endocarditis patient. The patient was 44 years old male patient with dilated right pupil and left hemiplegia. He was treated surgically by evacuation of intracerebral hematoma and excision of mycotic aneurysm. We also experienced another case of mycotic aneurysm with intracerebral hematoma in 17 years old male patient who had been suffered from fever of unknown origin. He was also treated surgically. We now reports 2 cases of mycotic aneurysm with intracerebral hematoma with a brief review of the literatures.
