1.Epizoological survey on infestation rate of helminths in Korean native cattle..
The Korean Journal of Parasitology 1971;9(2):54-57
The authors made a study on the species and distribution of helminths in Korean native cattle. The feces and internal organs from 1,755 heads were examined in slaughter plants of Taejon district. The results are summarized as follows. Distribution and infestation rate of helminths among the collected samples are, Paramphistomum spp. 68.4 per cent, Fasciola spp. 48 per cent, Eurytrema spp. 23.5 per cent, Moniezia spp. 8 per cent, Dictyocaulus spp. 3.5 per cent, Trichostrongylus spp. 12.4 per cent, and other species 26.8 per cent, respectively. In 33.4 per cent of ths cases, single infestation was seen and in 31.5 per cent, 18.0 per cent, and 14.0 per cnet mixed infestation of double, triple, and quadruple or more species were seen, respectively. Geographical analysis of infested helminths in the native cattle indicates: Among the trematoda order, Paramphistomum spp. and Fasciola spp. showed high rate of infestation throughout all districts of the country, especially Cheju island with a significant higher rate. Central district (Taejon) was higher in number of native cattle infested with Fasciola spp. than any other district of the country investigated. The rate of infestation with cestoda also showed to be higher in Cheju island than any other district of main land, but the rate of infestation with other nematoda showed no geographical difference.

The objective of this study was to establish a good methodology to isolate single smooth muscle cells that are alive and respond properly to pharmacological agents. Canine urinary bladders were employed as the source of single cells, and acetylcholine, atropine and imipramine were used as indicators of pharmacological responsiveness. Imipramine, an antidepressant drug exhibited the anticholinergic and calcium antagonizing properties on rat detrusor muscle. To establish a control value for a further experiment to elucidate the mechanism of action of imipramine on detrusor muscle, we measured the concentration-response of single cells to acetylcholine in the presesnce of imipramine by length of the cells and compared the result with the response in the presence of atropine. Tiny chops of smooth muscle taken from anesthetized canine urinary bladder were incubated in collagenase solution at 36℃ for 17-20 minutes. The collagenase solution included collagenase 1.2 mg/ml, soybean tryspin inhibitory 0.08 mg/ml, bovine serum albumin 2% in 10 ml Krebs-Henseleit buffer solution aerated with a consistent breeze of 95/5% O2/CO2 to maintain the pH at 7.4. After washing with plain K-H solution on 450 mesh, cells were dissociated from the digested tissue for 12-15 minutes. Cell suspension was transfered in 5 ml test tubes and acetylcholine was added for the final concentration to be 10⁻¹⁴~10⁻⁹M. To find the optimal time to fix the cells to determine the contractile responses, 1% acrolein was added 5, 10, 20, 30, 60 and 120 seconds after the administration of ACh. The length of cells fixed by acrolein were measured by microscaler vis CCTV camers on phaes-contrast microscope. The average length of 50 cells from a slide glass was taken as the value of a sample at the very concentration point. Single cells were isolated from canine detrusor. The length of untreated cells varied from 82 µm to 94 µm. The maximal response to actylcholine 10E-9M was accomplished within 5 seconds of exposure, and the shortening was 19±3%. Atropine reduced the contraction of the cells concentration-dependently. Lmipramine which exerts a cholinergic blocking action on some smooth muscles also reduced the contraction concentration-dependently and by a similar pattern as atropine. These findings document that imipramine may exerts a cholinergic blocking activity in the single smooth muscle cells isolated from canine urinary bladder.

The peripheral blood eosinophil and serum IgE level in 53 patients with atopic dermatitis (AD) were measured. The patients were divided into 2 groups by severity(mild and severe grous) and into 3 groups by the associated respiratory atopic deseases and/or their family history : respiratory group(patient, with both AD and respiratory atopy), family history group (patient with both AD and family history of respiratory atopy), and atopic group(patient with neither respiratory atopy nor family history of respiratorv atopy). We designed to study which factors are important in the elevation of serum IgE and peripheral blood eosinophil level in AD, and to know possible relationships between the serum eosinophil and IgE level and the several groups of AD. The results are as follows : 1. Peripheral eosinophil counts were higher in severe group(224.8/mm) than in mild group (180.0/mm)(p<0.05). 2. Peripheral eosinophil counts were 220.0/mm in atopic group, l65.0/mm in family history group, and 332.4/mm in respiratory group, but there was no stitistically significant difference among 3 groups. This suggests that concomitant respiatitiry atopy or a family history of respiratory atopy is not an important factor in the elvation of peripheral blood eosinophil counts in AD. 3. Serum IgE was higher in severe group(443.2IU/ml) than in mild group(231.5IU/ml)(p<0.05). 4. Serum IgE level in respiratory group(754.6IU/ml) were signifiiantlly higher than in atopic (286.6IU/ml) or family history group(342.0IU/ml)(p<0,01). But there was no significant. difference between family and atopic group. This result suggests that concomittent respiratory atopy is a potential factor in elevation of serurn Igi in AD. 5. Slightly high correlation between peripheral blood and IgE level appeared in all 53 patients (r=0.434) and severe group(r=0.480). But, respiratory group(r=0.060), family history group(r=0.111) and atopic group(r=0.202) showed poor relationships.

Type V hyperlipoproteinemia result from the accumulation of trglyceride(TG)-rich lipoproteins, very low density lipoprotein(VLDL), and chylomicrons. A 53-year old woman has showed asmptomatic, yellowish patches on tie palms and eyelids and papules on the knees with various types of xanthoma including xanthelasma palpebraum, xanthoma striatum palmare, anrl nonspecific papular xanthoma. The blood chemistry revealed a marked elevation of cholesterol and TG, and lipoprotein electrophoresis showed fasting chylomicronemia, prep-b and b-band, On histologic studies, typical foam cells were shown.

We report an unusual case of sebaceous hyperplasia in an 18-year-old male manifestated clinically as yellowish, grouped papules with a linear distribution, present on the right side of forehead since birth. Histopathologically, a large sebaceous gland composed of numerous lobules grouped around a centrally dilated duct was seen. The sebaceous lobules distributed in the upper dermis showed direct connection to the skin surface, which suggested a transepidermal elimination of sebaceous lobules.

We report a case of amelanotic melanoma(AMM) in a 53-year-old man who presented a single, 1.5×1.5cm sized, well-demarcated, bright red nodule with erosion on the right heel for 9 months. Histopathologic findings showed irregular junctional activity in the epidermal-dermal junction and alveolar formation in the dermis. The majority of the tumor cells were seen as bizarre and giant cell of epithelioid type with atypical mitotic figure. We could not find melanin pigment in H & E stain.

Numerous operations have been described to treat the recurrent anterior dislocation of the shoulder, but no one procedure was accepted as the choice of operation. We perforemed 6 Bristow procedures and 5 combined Bankart and Putti-Platt procedures and examined six shoulders by arthroscope from sep. 1989 to Sep. 1992, and we analysed the pathologic feature and the results of them. The average follow-up period was 2.2 years. 1. There were 8 males and 3 females and their average age was 33.7 years. The mean age in initial dislocation was 28 years. 2. The number of recurrent dislocation before operation was 17.9 times and the average duration of the disease was 5.7 years. 3. The pathologic lesions observed in intraoperative field were Hill-Sachs lesion (72.7%), Bankart lesion (90.9%), and the erosion of the glenoid rim (54.5%). On arthroscopic examination of 6 cases, Hill-Sachs lesion was found in 4 cases, Bankart lesion was seen in all of 6 cases, and the erosion of the glenoid rim was observed in 4 cases. 4. The average range of the limitation of external rotation was 17.3 and its significant difference was not observed between 2 operative groups. 5. By Rowes rating sheet, 4 cases of 5 combined Bankart and Putti-Platt operations were excellent and 1 case was good. 6. In conclusion, combined Bankart and Putt-Platt operation was considered as a good surgical procedure in the treatment of recurrent anterior dislocation of the shoulder.
