Serum Ig E Level in Koreal Sound Controls and Bronchial Asthmatics
Total serum IgE level were determined in 83
Korean sound controls (male 38, female 45) and 250
bronchial asthmatics (male 136, female 114) who had
not been treated with hyposensitization. The patients
were divided into two small groups, i. e. group (a)
with asthma only and group (b) with other coexistent
atopic diseases.
IgE in serum was measured by the radioimmunosorbent
technique using the kits of Phadebas~ and
following results were obtained.
1. In both control and asthma group, the frequency
distributions of the serum IgE levels were continuous ut not normal.
2. In control group, the serum IgE levels ranged
from 8 to 475 I.U./ml and the mean and the standard
deviation was 151Β±1l4 I.U./ml (male 151Β±124, female
152Β±105). There were no differences between sexes
or age groups
3. In patients group, the serum levels ranged from
33 to 7,200 I.U./ml and the mean and S.D. were 1401
Β±1412I.U./ml (male 1682Β±1420, female 1073Β±1217).
The levels of male patients were higher than those
of females. but the reasons were uncertain.
4. No significant differences were found between
the serum IgE levels in group(a) and those in group
(b).
5. The serum IgE level higher than 400I. U./ml was
thought to be significantly raised and such levels were
found in 4.8% of sound controls and in 74% of total
asthma patients. In the laller, the allergic bases may
play major roles in the pathogenesis of the disease
G. Significantly raised serum IgE levels were found
in 93% of the asthma patients under 10 years of age,
indicating the high prevalence of allergic asthma in
childhood
The expression of matrix metalloproteinases (MMPs), tissue inhibitor of metalloproteinases (TIMPs) and angiogenesis in relation to the depth of tumor invasion and lymph node metastasis in submucosally invasive colorectal carcinoma
BACKGROUND/AIMS: Lymph node (LN) metastasis occurs in approximately 10% of patients with submucosally invasive colorectal carcinoma. This study was performed to determine the role of matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs) production and microvessel formation on the LN metastasis in submucosally invasive colorectal carcinoma. METHODS: A total of forty-one subjects with surgically resected submucosally invasive colorectal carcinoma were included in this study. Immunohistochemical staining of MMP-2, MMP-9, TIMP-1, TIMP-2, and urokinase-type plasminogen activator were performed. Angiogenesis was evaluated by counting the number of microvessels in each pathologic specimen as identified by CD34 immunohistochemical staining. RESULTS: The depth of submucosal invasion was not significantly correlated with the expression of MMP-2, MMP-9, TIMP-1, TIMP-2, or urokinase-type plasminogen activator, but the microvessel count was significantly correlated with the absolute depth of invasion (r=0.312, p<0.05). Upregulation of TIMP-2 was positively correlated with adjacent lymphatic invasion (p<0.05) and increased TIMP-2 expression was correlated with LN metastasis in submucosally invasive colorectal carcinoma (p=0.088). CONCLUSIONS: These results suggest that the expression of TIMP-2 and the microvessel count may be useful parameters for considering additional surgery after endoscopic treatment of submucosally invasive colorectal carcinoma.
