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.

On the review of literature, various cases of osteomas orginated from paranasal sinuses can be found. But osteomas which are large enough to produce ocular symptoms are not very common. Even more, various ocular and intracranial sequelae may be complicated from surgical removal of huge frontal osteoma. We present a case of huge frontal osteoma which is originated from frontal sinus and removed successfully without any complications.

Most of glioblastoma multiforme in brain are known to be located supratentorially. On posterior fossa, they are mostly found in brain stem and cerebellar case is rare. A case of cerebellar glioblastoma multiforme is presented with the review of literatures.

BACKGROUND: Induction of anesthesia with propofol caused a decrease in arterial blood pressure and systemic vascular resistance. This effects of propofol on the circulation can be more clarified by studying cardiovascular control mechanism such as baroreflex sensitivity during variable rate infusion of propofol. METHODS: The effects of three infusion rates of propofol (3, 6, 12 mg/kg/hr) to supplement 66% nitrous oxide in oxygen anesthesia on baroreflex sensitivity were studied and compared with awake value in 80 ASA I or II patients (20-55 years old, n=20 in each group). Baroreflex control of heat rate was studied by pertubing the patients' arterial pressure with 100 microgram of phenylephrine in each three infusion rates of propofol which was maintained at least 30 min without any surgical stimulation. RESULTS: Baroreflex slope representing baroreflex sensitivity among three infusion rates of propofol did not show any significant differences. The slope of each infusion rate was 8.4+/-0.7 at awake, 8.9+/- 1.7 at 3 mg/kg/hr, 8.0+/-1.3 at 6 mg/kg/hr, 7.2+/-1.0 at 12 mg/kg/hr, respectively. But, resetting of the reflex occured at low heart rates. CONCLUSIONS: Usual propofol-nitrous oxide-oxygen anesthesia was not associated with impairment of baroreflex sensitivity, but showed reflex resetting at low heart rates.
