Title: Hemolytic streptococcus preparation having improved antitumor activity
Inventor: KATAOKA MOTOYUKI
IPC: A61K35/74
Filed: 1988-06-30
Abstract: PURPOSE:To obtain a hemolytic streptococcus preparation having increased antitumor activity, by using a hemolytic streptococcus having lowered toxicity, e.g. A-group Streptococcus pyogenes Su strain and treating the strain with a proteinase. CONSTITUTION:The titled preparation can be produced by treating a hemolytic streptococcus having lowered toxicity with a proteinase (e.g. pepsin or trypsin). The hemolytic streptococcus is preferably an attenuated strain, e.g. A-group Streptococcus pyogenes Su strain. The strain is treated with an antibiotic substance (e.g. penicillin G, cephalosporin C or cycloserine) to obtain an attenuated strain (e.g. PCB-45 or OK-432), which is treated with a proteinase at pH0.1-8.0 for 20-50min. The attenuation treatment with the antibiotic substance is carried out by suspending living bacterial cells in a medium containing the antibiotic substance, maintaining the suspension at 30-38 deg.C and heat-treating at 40-50 deg.C.

Title: Cooler and cooling system employing it
Inventor: HARASHIMA YUJI
IPC: F25B1/00
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To perform cooling without generating noise while reducing the size and weight by stacking a heat pipe and a Peltier element. SOLUTION: Two Peltier elements 2 and two heat pipes 1 are stacked to constitute the cooler body and a heat transfer plate of aluminum, or the like, is laid on the lower surface of a Peltier element 2 located at the lowermost stage thus constituting a cooler A. Since a fan generating wind cut noise is not used, a heat source object can be cooled effectively. More specifically, heat carrier in the heat pipe 1 absorbs heat of the object to be cooled to cause gas-liquid phase conversion and heat is transmitted to the heat pipe 1 being cooled by the Peltier element 2. Consequently, heat is moved effectively from the object to be cooled using a small and lightweight cooler and cooling efficiency of the object to be cooled can be enhanced.
