Endotoxin in patients with terminal renal failure undergoing dialysis with re-processing dialyser.

Aim: to determine the level of endotoxin in the blood of patients with renal failure prior to and following hemodialysis using re-processing dialyser to know possibility of pyrogenic reactions in hemodialysis patients.

Methods: this study subjects consisted of 10 patients with terminal renal failure undergoing regular hemodialysis. The collected samples were then sent in frozen condition for endotoxin examination in Japan.

Correlation between cortisol levels and myocardial infarction mortality among intensive coronary care unit patients during first seven days in hospital.

Aim: To measure cortisol level, its relationship with myocardial infarction, and to determine the correlation of elevated cortisol levels with the outcome of myocardial infarction.

Methods: This study was designed as a pre and post study. The diagnosis of myocardial infarction was established based on the WHO criteria.

Renal involvement in leptospirosis at Dr. Cipto Mangunkusumo and Persahabatan Hospitals.

Aim: To describe clinical pattern of ARF caused by leptospirosis and its related factors.

Methods: A cross-sectional study using medical record data of all leptospirosis cases admitted to Cipto Mangunkusumo and Persahabatan General Hospitals between January 1993 and December 1996. Patient identification included age, sex, and occupation.

Micromechanical models for the Brownian motion of hair cell stereocilia.

Brownian motion of the hairs (stereocilia) of amphibian hair cells has been shown in experiments to be in the range of some nm. Our models of the Brownian motion of coupled harmonic oscillators with mechanical properties of stereocilia lead to similar displacements. Computer simulation shows that stochastic fluctuations enhance the encoding of low level acoustic signals.
