1.The role of transbronchial fine needle aspiration in the diagnosis of submucosal bronchogenic carcinoma
Journal of Medical Research 2002;18(2):7-12
Transbronchial needle aspiration in the diagnosis of submucosal bronchogenic carcinoma. Although exophytic endobronchial lesions can readily be diagnosed by forceps biopsy through the rigid bronchoscope. The lesion of submucosal or peribronchial by forceps biopsy difficult to diagnose by biopsy. The utility of transbronchial fine needle aspiration through rigid bronchoscope was made in 98 patients presenting with endoscopic abnormalities suggestive of submucosal bronchigenic carcinoma of respiratory department of Bachmai hospital from 3/1991 to 7/1996. Forceps biopsy was positive in 48 patients (58.77%). Transbronchial needle aspiration was positive in 88 patients (88.79%) and detected 6 cases additional carcinomas (who were treated by anti-tuberculosis of the lung). We concluded that TBNA significantly increases the yield, more effective than forceps biopsy alone in the detection of the infiltration of submucosal bronchogenic carcinoma.

PURPOSE: The purpose of this study is to investigate the effect of the suction time in forming the corneal flap with microkeratome on the corneal flap thickness. METHODS: Thirty porcine eyes were randomly assigned into 3 groups according to suction duration: group 1(10 sec), group 2(35 sec) and group 3(60 sec). The Hansatome microkeratome with 160 plate and a suction ring with 8.5mm diameter were used to create corneal flap. The thickness of central cornea was measured with automated ultrasound pachymeter before the procedure. And after making the flap, the remained corneal thickness was measured with the same method. Then, the difference between the two values was thought to be the corneal flap thickness. RESULTS: The mean corneal flap thickness in group1, 2, and 3 were 91.0+/-24.1 micromiter, 110.1+/-8.9 mu m and 127.2+/-6.1 mu m, respectively. The difference was significant among the three groups(p=0.010), and the longer suction duration made the flap thicker. CONCLUSIONS: These results suggest that in forming the corneal flap with microkeratome, the suction duration has an effect on the corneal flap thickness and an increase of suction duration makes the flap thicker in porcine eyes.

PURPOSE: To evaluated the effect of suction ring on eyeball contour and its influence on the corneal flap made in LASIK(laser in situ keratomileusis). METHODS: We measured corneal thickness and axial length of 47 eyes, before and during application of the suction ring, in those which had undergone LASIK. The diameter and thickness of corneal flap made with Automated Corneal Shaper(R) were also measured in operation room. RESULTS: When applying suction ring while making a corneal flap, corneal thickness and axial length were decreased significantly(p<0.05), and the diameter of the flap was decreased as preoperative corneal curvature decreased(p<0.05). CONCLUSIONS: Careful attention is needed not to give an eyeball unnecessary pressure which may result in intraocular damage or flap complications such as free cap especially when their corneal curvature is too flat.

Human epidermal cells were obtained from suction blisters of 14 healthy individuals, and were cultured for 24-96 hours st a concentration of 1x 10(7)/ml, 5 x 10(6)/ml, 1 x 10(6)/ml, 5 x 10(5)/ml. Cells were also cultured with or without stimulants such as phorbol myristic acetate(PMA), muramyl dipeptide(MDP), and endotoxin. Then, cell-free supernatants of cultured epidermal cells were tested for ETAF by a thymocyte prolifera.tiom assay. The results were as follows : 1, The highest activity of ETAF was produced by fresh epidermal cells(EC) at a concentration of 1 x10(7)ml. Its highest 3H-TdR was 4928+/-2480cpm. The highest activity of ETAF was produced by cultured EC at a concentration of 5 x10(6)/ml. Its highest 3H-TdR was 13983+/-8045 cpm. 2. The highest activity of ETAF was produced by fresh EC with n culture time of 24 hours. Its highest 3H-TdR was 5357+/-3760cpm. The highest activity of ETAF was produced by cultured EC with a culture time of 72 hours. Its highest 3H-TdR was 11905+/-5327cpm. 3. The highest activity of ETAF was produced by both fresh and cultured EC at a titer of 1: 8 dilution of cell-free supernatants. 1ts highest 3H-TdR was 4928 +/-2480cpm in the fresh EC, and 11905+/-5327cpm in the cultured EC. 4. Alhen fresh EC was stimulated with PMA, MDP and endotoxin, higher activity of ETAF was found in the group stimulated with PMA or MDP compared with its control group. But lower activity of ETAF was found in the group stimulated with endotoxin compared with its control group. The 3H-TdR was 6000+/-1936 cpm in the group stimulated with PMA, 6945+/-3182 cpm in the group stimulated with MDP, and 36943+/-36861cpm in the group stimulated with endotoxin.

PURPOSE: Regarding the respiratory function of patients with an artificial airway, this study compared the effects between normal saline with chest vibration and normal saline with expectorant mixture, administered before endotracheal suction. METHODS: The study was conducted in the ICUs of one university hospital located in Incheon. The experimental group I received normal saline with chest vibration administered before endotracheal suction while the experimental group II received normal saline with expectorant mixture administered before endotracheal suction. For respiratory function, PaO2, PaCO2, and O2 saturation were measured by ABGA at 3 minutes after endotracheal suction for both pre-test and post-test. RESULTS: The two groups were not different significantly regarding PaO2 level and O2 saturation after the treatments, while, the experimental group II had lower PaCO2 level than the experimental group I after the treatments (t = 2.075, p = .042). For experimental group II, post-test score of PaCO2 level was significantly lower than that of the pre-test score (t = 1.842, p = .075). CONCLUSION: The administration of normal saline with expectorant mixture before endotracheal suction reduced PaCO2 level and improved the respiratory function.

9.Results of treatment of brain abcesses by 2 methods: needle aspiration and capsula removal
Journal of Vietnamese Medicine 1998;255(6):83-87
The records of 75 patients with brain abscesses treated over 7 years were analysed. Congenital cardiopathies were the most frequent causes of abscess. Organisms were identified in 74.07% of the cultures from abcesses speciment. The patients were grouped according to the treatment received: excision (n=42) aspiration (n=33). There were no significant differences is the mortality rates between the two groups. Patients treated by aspiration had a significantly less morbidity than patients treated by excision. Early and aggeressive treatment can result in an excellent outcome in the large majority of patients.
