Matrix metalloproteinases are believed to play an important role in tumor invasion and metastasis. But little is known about the role of them in the gastric adenocarcinoma. We investigated the expression of matrix metalloproteinase-1,2,3 in eighty paraffin blocks of the primary gastric adenocarcinoma tissues with immunohistochemistry and analysed their correlation with lymph node metastasis and survival. MMP-1,2,3 were expressed most intensely in the fibroblasts around the tumor stroma. In our study the increased immunoreactivity of MMP-2 only showed statistically significant correlation with lymph node metastasis (P=0.0517, Odd's ratio=2.274). But MMP-1,2,3 all were correlated with survival. Type IV collagen was observed in the vascular basement membranes and tumor basement membranes and showed statistically significant correlation with lymph node metastasis (P=0.0002, Odd's ratio=0.194) and prognosis (P=0.0001). The immunoreactivity of MMP-2 and type IV collagen was inversely correlated (Kendall's Tau-b correlation = 0.37482, P=0.0001). Our results suggest that in human gastric adenocarcinoma the increased immunoreactivity of MMP-2 and the decreased immunoreactivity of type IV collagen has an important role in lymph node metastasis and prognosis. MMP-1,3 are not correlated with lymph node metastasis but correlated with survival. The mechanism responsible for the production of MMP by the host fibroblasts remains obscure and requires further investigation.

Enemas are sometimes used in hospital and domicilliary practice and occasionally by patients themselves without a valid indication. The present repart is one in which enernas were done for 3 months by a patient himself to treat his hemorrhoid and resulted in severe inflamimatory change with large-siaed illdefined shallow ulceration in rectum and sigmoid colon. This patient, a 53 year old male, entered the hospital with the complaint of diarrhea with passage of bloody muct.. Colonoscopic examination revealed severe inflammatory change, friable mucosa and several relatively large-sized ill-defined shallow ulceration in rectum and sigmoid colon. A biopsy was performed and microscapic examination revealed intense infiltrates and plasma cells and crypt abscess with decreased goblet cells in the lamiina propria. The submucosa showed edema with infiltrates of chronic inflammatory cells and neutrophils. Conservative treatment with discontinue of enemas and fluid supply was performed. And his symptoms were improved. After second week, follow-up colonoscopy revealed inflammatory changes were improved.

BACKGROUND: This study was designed to compare the hemodynamic changes in response to direct laryngoscopy of the McCoy blade and the Macintosh blade. METHODS: Sixty patients scheduled for elective gynecologic surgery were randomly allocated into two groups. The induction of anesthesia was done with thiopental sodium 5 mg/kg, fentanyl 2 mcg/kg, vecuronium 0.1 mg/kg. When the train of four arrived came at 0/4, the vocal cords were visualized with either the McCoy or the Macintosh laryngoscope blade for 10 seconds. Heart rate and blood pressure were recorded at 1 minute intervals for 5 minutes. RESULTS: Laryngoscopy caused significant increases in arterial blood pressure in both groups, while it had no effect on heart rate in either group. There were no significant differences in blood pressure and heart rate responses to laryngoscopy in the blades. CONCLUSIONS: The McCoy and the Macintosh blade show similar changes in heart rate and blood pressure after laryngoscopy.

The process of cancer metastasis is dependent on the cancer cells’ capacity to detach from the primary tumor, endure in a suspended state, and establish colonies in other locations.Anchorage dependence, which refers to the cells’ reliance on attachment to the extracellular matrix (ECM), is a critical determinant of cellular shape, dynamics, behavior, and, ultimately, cell fate in nonmalignant and cancer cells. Anchorage-independent growth is a characteristic feature of cells resistant to anoikis, a programmed cell death process triggered by detachment from the ECM. This ability to grow and survive without attachment to a substrate is a crucial stage in the progression of metastasis. The recently discovered phenomenon named “adherent-to-suspension transition (AST)” alters the requirement for anchoring and enhances survival in a suspended state. AST is controlled by four transcription factors (IKAROS family zinc finger 1, nuclear factor erythroid 2, BTG anti-proliferation factor 2, and interferon regulatory factor 8) and can detach cells without undergoing the typical epithelialmesenchymal transition. Notably, AST factors are highly expressed in circulating tumor cells compared to their attached counterparts, indicating their crucial role in the spread of cancer.Crucially, the suppression of AST substantially reduces metastasis while sparing primary tumors. These findings open up possibilities for developing targeted therapies that inhibit metastasis and emphasize the importance of AST, leading to a fundamental change in our comprehension of how cancer spreads.
8.A Case of Idiopathic Orbital Inflammation Presenting as Isolated Myositis of the Inferior Oblique Muscle
Journal of the Korean Ophthalmological Society 2021;62(9):1309-1314
Purpose:
To report a case of idiopathic orbital inflammation presenting with isolated myositis of the inferior oblique muscle. Case summary: A 54‐year‐old man presented with swelling on the left lower lid, pain on superonasal and inferonasal gaze, and binocular diplopia for 2 months. His head was tilted to the right by about 5° and mild conjunctival injection and 3 mm narrowing of palpebral fissure of the left eye compared to the other eye were observed. Eight prism diopter (PD) left hypertropia and 4 PD intermittent esotropia were noted on primary gaze, which worsened on leftward gaze, downward gaze, and left head tilt. Orbital magnetic resonance imaging (MRI) showed enhanced hypertrophy of the left inferior oblique muscle. Systemic work‐up for possible inflammatory diseases yielded negative results. Therefore, a presumptive diagnosis of idiopathic isolated myositis of the left inferior oblique muscle was made. The patient was treated with 60 mg of oral corticosteroid per day for the first week, and the dose was tapered for 1 month as the symptoms reduced. Two months later, the patient became free from any symptoms and follow-up orbital MRI showed a significant decrease in size of the left inferior oblique muscle. There have been no signs of recurrence for 7 months.
Conclusions
A presumptive diagnosis of idiopathic isolated myositis of the inferior oblique muscle was made in a patient with swelling of the left lower lid and binocular diplopia based on orbital MRI and systemic work‐up. Good results were achieved with oral corticosteroid therapy.

The overt effects of the anticancer drugs such as cisplatin and taxol appear to be DNA modification and microtubule stabilization respectively. But the mechanism by which these drugs affect tumor cell cycle perturbation and their correlation to apoptosis and cytotoxicity are not well understood, especially in combined sequential treatment of cisplatin and paclitaxel (taxol). In this study, to elucidate the action mechanisms as a function of cell cycle changes and cytotoxicities and to determine the adequate treatment sequence of cisplatin and taxol to acquire more enhanced cytotoxic effects when they are combined, we evaluated the cell cycle perturbations and its correlation to cytotoxic effects, which is measured by the extents of apoptosis and the fractions of cellular debris and live cells after combination treatment of cisplatin and taxol changing their treatment sequences in NIHOVCAR-3 ovarian cancer cell line. Our results were as follows; (1) The accumulation in S phase inhibited the entrance of tumor cells to G2M phase when the cisplatin treatment was preceded to taxol in their combination. (2) The tumor cells were not accumulated in S phase but most of them entered to and accumulated in G2M phase and they were leading to cell death when the taxol treatment was preceded to cisplatin in their combination. (3) Apoptotic peaks in taxol pretreatment group were detected earlier and persisted longer than that of cisplatin pretreatment group. (4) The cytotoxicities represented by the decreased fractions of live cells and the increased fractions of cellular debris were higher in taxol pretreatment group than those of cisplatin pretreatment group. These results suggested that the taxol pretreatment is more effective in combination of cisplatin and taxol and the relative decrease in the cytotoxicity in cisplatin pretreatment group was considered to be derived from the inhibition of entrance of tumor cells to G2M and protected them from the action by taxol. From these results, we concluded that the taxol pretreatment will enhance the cytotoxic effects to tumor cells when cisplatin and taxol will be administered and it indicates that correlations between cell cycle perturbation, apoptosis and cell death have to be considered in the future combination treatment of other drugs and in the development of new treatment regimens.
