2.Studies on Wound Infection - I. Isolation of Microorganisms in the Operating Theater .
Korean Journal of Anesthesiology 1972;5(1):37-49
In search of the best preventive measures against postoperative wound infections, the author has conducted a series of studies which preliminary results are as follows. (1) There were no postoperative secondary infections in 50 surgical cases except in one, which had undergone dacryocystorhinostomy. (2) More than one strain of microorganism were isolated from all of 20 operator's nostril, throat, and peritonsillar region. It is strongly suggested that operators and hospital workers play an important role in the cause of hospital infection. (3) Some difference in the strain of organisms isolated were noted between the countrymen and townsmen. (4) It is urged to pay particular attention to sterilization for lowere abdominal surgery. (5) Chloramphenicol exerted an sustained and excellent broadspectrum antimicrobial activity to various microorganisms.

BACKGROUND/AIMS: The Helicobacter pylori(H. pylori) infection induces gastric mucosal injury through the various bacterial cytotoxins, the inflammatory reaction of the host and the increased gastric acid secretion. Urease is a kind of adaptive protein of H. pylori to survive in strong acid environment of the stomach, may increase the pH of the gastric mucosal surface and induces gastrin release by the feedback mechanism. This study was performed to evaluate whether 0.1% phenol red solution without urea is useful as a pH indicator of the gastric mucosa for the diagnosis of H. pylori infection in stomach and whether the pH of the gastric mucosal surface is changed by H. pylori infection. METHODS: The gastric mucosa was stained by 0.1% phenol red solution without urea during endoscopy in 89 patients with non-ulcer dyspepsia. The patterns of staining of the gastric mucosa were divided into unstained, patchy regional and diffuse staining by the area of color change from yellow to red. The pH of the gastric mucosal surface was measured directly on the stained and unstained areas of the gastric mucosa by using pH meter and antimony pH electrode through the biopsy channel. RESULTS: The pH of the stained areas after spray of phenol red solution was significantly higher(6.9) than that(1.9) of the unstained gastric mucosa(P<0.01). The patterns of the staining were different between antrum and body. The patterns of unstaining and patchy staining were more common in the body than in the antrum. But the patterns of regional and diffuse staining were more common in the antrum than in the body(P<0.05). The positive rates of H. pylori in antrum, body and total gastric biopsies were higher in stained than in unstained mucosa significantly(P<0.05). Severity of active inflammatory reactions was higher in stained mucosa than unstained mucosa in the antrum. But there was no difference in severity of active inflammatory reactions between stained mucosa and unstained mucosa in the body. CONCLUSIONS: 0.1% phenol red solution without urea is useful as a pH indicator for the diagnosis of the H. phlori infection in the stomach. H. pylori infection may increase the pH of gastric mucosal surface and induce severe active inflammation of the gastric mucosa in non-ulcer dyspepsia.

Familial Parkinson's disease (PD) has been linked to point mutations and duplication of the α-synuclein (α-syn) gene. Mutant α-syn expression increases the vulnerability of neurons to exogenous insults. In this study, we developed a new PD model in the transgenic mice expressing mutant hemizygous (hemi) or homozygous (homo) A53T α-synuclein (α-syn Tg) and their wildtype (WT) littermates by treatment with sub-toxic (10 mg/kg, i.p., daily for 5 days) or toxic (30 mg/kg, i.p., daily for 5 days) dose of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Tyrosine hydroxylase and Bcl-2 levels were reduced in the α-syn Tg but not WT mice by sub-toxic MPTP injection. In the adhesive removal test, time to remove paper was significantly increased only in the homo α-syn Tg mice. In the challenging beam test, the hemi and homo α-syn Tg mice spent significantly longer time to traverse as compared to that of WT group. In order to find out responsible proteins related with vulnerability of mutant α-syn expressed neurons, DJ-1 and ubiquitin enzyme expressions were examined. In the SN, DJ-1 and ubiquitin conjugating enzyme, UBE2N, levels were significantly decreased in the α-syn Tg mice. Moreover, A53T α-syn overexpression decreased DJ-1 expression in SH-SY5Y cells. These findings suggest that the vulnerability to oxidative injury such as MPTP of A53T α-syn mice can be explained by downregulation of DJ-1.
