1.IV-gamma Globulin Therapy for Severe Abdomlnal Pain Refractory to Steroid Therapy in Henoch-Scholein Purpura.
Journal of the Korean Society of Pediatric Nephrology 1997;1(2):176-178
To make the objective standard of nuclear size in grading nuclear pleomorphism of invasive ductal carcinoma of the breast, we measured maximal nuclear diameter of tumor cells on imprint cytology slides and histologic sections from 65 cases by using computer-based image analysis system (Optimas 6.0). The maximal diameter of red blood cells were also measured to evaluate the ratio of maximal nuclear diameter of tumor cells to maximal diameter of red blood cells. The mean values of maximal nuclear diameter of tumor cells on imprint cytology slides and histologic sections were 7.56microgram, 7.53microgram in nuclear grade 1, 8.92+/-0.98microgram, 9.02+/-0.74microgram in nuclear grade 2, and 12.90+/-1.47prn, 12.44+/-1.41microgram in nuclear grade 3, respectively. There were no significant differences between values of imprint cytology and histologic section. The ratio of maximal nuclear diameter of tumor cells to maximal diameter of red blood cells were 1.3-1.4:1 in nuclear grade 1, 1.6-1.7:1 in nuclear grade 2, and 2.2-2.3:1 in nuclear grade 3. Ths would be guidelines for grading nuclear pleomorphism of invasive ductal carcinoma of the breast on routine surgical pathology work.

2.Experimental Cyclocryothermy in Rabbits.
Journal of the Korean Ophthalmological Society 1970;11(1):7-12
The effects of Cryosurgery of the ciliary body on the aqueous humor dynamics of ten albino rabbits were studied by perfusion experiments. The cryo-probe (tip diameter, 3 mm) was frozen by dry ice and alcohol mixture and applied over the full circumference of the eye 2 mm from the limbus for 30 seconds. Eight applications were made in each eye. Intraocular pressure fell during the first 10 days after surgery, the amount of fall averaged 2.5 mmHg (12.6% of the pre-treatment level). Thereafter the intraocular pressure rose gradually in all eyes and reached almost to the original level 3 weeks after surgery. Facility of outflow changed inconsistently, showing no definite pattern. Aqueous flow showed significant reductions during the 2 to 3 weeks after treatment, then gradually recovered. There was no significant reduction in flow after the end of 3 weeks. No complications were encountered except mild iridocyclitis during the first week. The unsatisfactory outcome of this cryotherapy is considered to be due to the insufficient freezing of the ciliary body, and more applications is recommended in order to produce more sustained reduction of intraocular pressure.

To address the possible prognostic value of p53 and Bcl-2 proteins in non-small cell lung carcinomas (NSCLCs), the authors studied 43 cases of NSCLCs diagnosed between the years 1990 to 1995 at Pusan National University Hospital. The patients were treated either by pneumonectomy or lobectomy of the lung. The expression of p53 and Bcl-2 proteins was semiquantitatively analyzed in paraffin sections by immunohistochemical method and correlated with clinicopathologic prognostic parameters of NSCLCs. Overexpression of the p53 protein was found in 31 cases (72.1%) of the 43 NSCLCs. Overexpression of the p53 protein was significantly correlated with the decreasing degree of histologic differentiation, increasing tumor stage, and cigarette smoking. Bcl-2 expression was found in 19 cases (44.2%) of the 43 NSCLCs. Increased expression of the Bcl-2 protein was significantly correlated only with decreasing tumor stage. An inverse relationship was found between p53 and Bcl-2 proteins, but it was not statistically significant. Thus p53 and Bcl-2 proteins, as demonstrated immunohistochemically in routine paraffin sections, could be of value in prediction of the aggressiveness and prognosis of NSCLCs, in agreement with the central role of p53 and Bcl-2 proteins in the evolution of NSCLCs associated with cigarette smoking.

Acral persistent papular mucinosis is a subtype of the localized papular mucinosis. Clinically, ivory to flesh-colored papules develop exclusively on the back of the hands, the extensor surface of the wrists, and occasionally the distal forearms. Histologically, mucin accumulates in the upper reticular dermis, typically sparing a subepidermal zone and fibroblasts are not increased in number. On experiencing a case of numerous papules on both hands and forearms of a fifty year-old woman, we present it as acral persistent papular mucinosis.

BACKGROUND: In the most of emergency department, the diagnosis of appendicitis has been carried by clinical history, physical examination and plain X-ray. But the diagnostic accuracy by these methods was so low that unnecessary operation was common performed, and sometimes the operation was delayed till the physicians could confirm the acute appendicitis clinically. Although many kinds of diagnostic tools such as CT scan, laparoscope, and etc, we believe that ultrasonography(US) would be a quick and sensitive diagnostic method for the evaluation of acute appendicitis in the Emergency Department. METHODS: Forty-seven patients who were clinically suspected as acute appendicitis were evaluated with the grayscaled US by emergency physician. The probe of US was placed on maximal tender point of abdomen, and the appendix image was evaluated while probe was pressed deeply and gentry. When the blind loop was fecund at maximal tender point of abdomen, we evaluated the diameter of appendix, the presence of compressibility, peri-aspen-diceal fluid collection and other mass effect. As soon as the ultrasonographic evidences of the appendicitis were noticed, the operations were done and pathologic report were reviewed later. RESULTS: Among the forty-seven patients, forty patients were diagnosed as a appendicitis by US, and most common ultrasonic findings were as follows; 1) non-compressible blind loop larger than 5 mm in diameter, 2) wall thickening more than 3 mm, 3) peri-appendiceal fluid collection, 4) periappendiceal mass. Among remaining 7 patients in whom we could not get any positive findings of appendicitis, abdominal CT scan was carried in 2 cases who had direct and rebound tenderness on right lower abdomen, and CT scan showed the evidences of the appendicitis. The other 5 cases without rebound tenderness were observed far 2 hours, and abdominal pain was disappeared lately. Finally forty-two patients were operated and confirmed as acute appendicitis by pathologic reports; 24 were reported as suppurative appendicitis, and 12 cases of gangrenous appendicitis, 3 cases of perforated appendicitis, and 3 cases were peri-appendiceal abscess. The specificity of US in the diagnosis of acute appendicitis was 71.4%, and the sensitivity was 95.2%. CONCLUSIONS : In some patients suspected appendicitis, emergency physicians could diagnosis acute appendicitis accurately and rapidly by use of ultrasonography. Although the US was an actuate imaging modality to diagnosis acute appendicitis and evaluate its complications, we recommend a laparotomy or abdominal Cf scan in the patients with negative US findings in spite of presence of peritoneal irritation signs such as rebound tenderness and/or muscle guarding on right lower abdomen.
