We have recently experienced a case of mammary hamartoma in 29-year-old woman. Hamartoma of the breast is a rare benign tumor-like lesion which is characteristically well demarcated by thin layer of fibrofatty tissue and composed of essentially normal mammary tissue with mammary glandular structure and fibrous stroma containing variable amounts of fat. The lobular architecture is relatively well preserved. It can be readily recognized, but should not be confused with fibroadenoma or mammary dysplasia. It also shows characteristic mammographic picture.

The pancreas consists of two types of tissue arising from same primitive cells, but with entirely different functions. Although the adult human pancreas and fetal islet tissue have been the subject of numerous electron microscopic studies, little is known of the ultrastructure of the developing human exocrine pancreas. The purpose of the current study is to investigate development of endo and exocrine of pancreas, especially during the middle trimester of human fetal life, which is the period of acinar cell maturation. Fresh autopsy specimens of pancreas, taken from 15 human fetuses at the 12th (n=2), 13-16th (n=5), 17-20th (n=4), 21-24th (n=2) and 25-28th (n=2) weeks of gestation, were studied electron microscopically, and immunohistochemically. Antisera against insulin, somatostatin, glucagon, pancreatic polypeptide and gastrin, were used for immunohistochemistry. By the 12th week, primitive exocrine acini were identified and these were matured rapidly in the next 6 weeks. At the 17th week stage, ultrastructural examination revealed atypical zymogen granules in the acinar cells. These became progressively less numerous in the 21-28 week period when classical zymogen granules increased upto the level of adult stage. All the endocrine cells were found at the 12th week, forming primitive or mature islets. The relative ratio of endocrine cells at the 12th week was about 35.4%, 24.9%, 39.8%, 0.5% for A, B, D & PP cell, respectively. But at the 25th to 28th week of development, the relative numbers of A and D cells decreased somewhat, whereas those of the B cells increased. The PP cells were constant. The G cells were found at the 12th week of fetal period, which appeared through out the on period.

Fisting is an uncommon sexual activity, and death due to fisting is very rare. In the present report, we describe a case of a woman who died from fisting by her male partner. A 38-year-old woman went to a motel with a man after consuming alcohol, and there they kissed each other. As desired by woman, the man inserted his fingers into her vagina and anus, and later inserted his fist and forearm into her vagina and anus. After 20-30 minutes of fisting, the woman became unconscious and died. The autopsy confirmed the presence of perineal and vaginal lacerations with massive internal pelvic soft tissue injury with uterine artery rupture. A partial tear was noted at the rectosigmoid junction. The cause of death was hypovolemic shock due to uterine artery rupture. Following court trials, the assailant was sentenced to 4 years of imprisonment for the felony of inflicting bodily injury resulting in death.

Urinary retention is a common complication after abdominal surgery. Urinary retention causes infection and damage to the urinary system, prolonging hospital stays and increasing health care costs in the end. Because medical personnel tend to regard urinary retention as not being a serious problem, it is hard to find any method which decrease the postoperative urinary retention. There are few papers reporting the incidence and the factors which influence the postoperative urinary retention. The purpose of this study is to evaluate the incidence of postoperative urinary retention and to identify the factors which affect the postoperative urinary retention. We retrospectively reviewed 296 patients out of 338, who had been undergone laparotomy under spinal or general endotracheal anesthesia during a three month period from January to March 1998. We reviewed nursing, anesthetic and operative records. Among the 296 patients, male were 189(63.9%) and female were 107(36.1%). Postoperative urinary retention occurred in 71 patients(24%). The incidence rate was higher in female patients than in male (M : F=18% : 35%). Factors that in fluence the incidence of postoperative urinary retention were sex, duration of operation, the amount of fluid given the patient, preoperative history of dysuria, and preoperative insertion of a urinary catheter. Among those factors, preoperative urinary catheter insertion is the most effective preventive measure in lowering the incidence of postoperative urinary retention (Spearman correlation coefficient, r=-.462). Shortening the operation time and sparing the fluid which is infused during operation are important in preventing postoperative urinary retention. Preoperative urinary catheter insertion may be helpful in lowering urinary retention in those patients who have a possibility of postoperative urinary retention.

Alveolar soft-part sarcoma is a rare malignant neoplasm. It occurs most commonly in the deep tissue of the extremity, particularly in the anterior aspect of the thigh. It usually presents as a slow-growing, painless mass with little functional impairment. Because of the relative lack of symptoms, it may be easily overlooked. The course of the disease tends to be long but unrelenting, and local recurrences are frequent. There were no lifetime cures in the reported cases. This tumor is relatively unknown to orthopaedic surgeons, and a wider knowledge of its characteristics may lead to its more frequent recognization, Recently, two cases of alveolar soft-part sarcoma were encountered on the orthopaedic department of Dong-kang Hospital, Ulsan. In case 1, the tumor was found in the vastus lateralis muscle; and in case 2, vastus intermedius muscle. The authors will present these cases in detail to provide a glance at this very rare but more frequently recognizable tumor, the alveolar soft-part sarcorna.

The purine antimetabolite 6-Mercaptopurine (6-MP) has been in clinical use for over 30 years and is still a widely used agent in the treatment of childhood acute lymphoblastic leukemia. The bioavailibility, clinical efficacy and toxicity of 6-MP administered orally for maintenance therapy of children with acute lymphoblastic leukemia are highly variable in many studies, as well as at differnt times in same patient. there are many factors affecting the bioavailibility of 6-MP. The most notably factor being that concomitantly administered drugs and foods might contribute to a decrease in the bioavailibity of this drug. In our sociocultural environment milk is a major constituent of child's foods. Cow's milk contains a high concentration of xanthine oxidase, which could potentially transform 6-TM into 6-thioxanthine (6-TX) and 6-thiouric acid (6-TUA) which have no more therapeutic effects. In this study, we evaluated the effect of various milk products on the bioavailability of 6-MP. Incubation at 37degrees C for 30 min raw or pasteurized milk resulted in transformation of a large quantity of clinically relevant concentration of 6-MP into 6-TUA. The concomitant adminstration of folic acid and allopurinol has markedly inhibitory effect on the 6-MP destroying activity of milk at clinically relevant concentrations. These observations may help to optimize modalities of administration of 6-MP for the treartment of patients with childhood leukemia.

This study was for investigating relations between distributions of monoamines-norepinephrine, serotonin, and dopamine-on the visual system and their functions. Distributions of these monoamines in the lateral geniculate body, pulvinar, lateral posterior nucleus, and suprachiasmatic nucleus were investigated. Brain of a squirrel monkey was removed and frozen sectioned. Immunocytochemical study was performed for the tissue of the brain. Results showed that the anterior part of the lateral geniculate body contained more monoamines than the posterior part. More serotonins were distrbuted at the magnocellular part, and more dopamines were found at the parvocellular part. In pulvinar, more norepinephrines were distributed at the medial part, while serotonins were evenly distributed at all parts. In lateral posterior nucleus and suprachiasmatic nucleus, three kinds of monoamines were distributed with high density. Among the three, density of the serotonin showed the highest value. The lateral geniculate body relates with visual perception such as visual acuity, form and color perception, and stereopsis, while the pulvinar relates with visual functions, such as visual attention, sensory integration, and differentiation. Since norepinephrine and serotonine are distributed with high density in the pulvinar than in the lateral geniculate body those two monoamines are expected to playa major role for visual functions. Inferior part of the pulvinar relates with visual imagination, and the lateral posterior nucleus relates with integration of visual sensory. Relatively high distribution of dopamine in these two parts means that dopamine may playa major role for visual imagination and integration. As suprachiasmatic nucleus relates with controlling biorhythm, dense distribution of monoamines in suprachiasmatic nucleus implies that the monoamines may work for controlling biorhythm.

Eyelid has rare infection and good wound healing due to rich blood supply, but often lead to excessive bleeding during surgery. Thus, bleeding control in time of operation is very important to secure operation field and minimize subcutaneous hemorrhage and edema after operation. Retrospectively, we analized intra- and post-operative complications of 92 patients who had undergone eyelid surgeries by one operator using Colorado patients who had undergone eyelid surgeries by one operator using Colorado dissection needle attached to monopolar electrocautery from March to October 1997. there were 49 patients of epiblepharon or entropion, 16 patients of ptosis, 10 patients of dermatochalasis and 17 patients of blepharoplasty. In all 92 patients who had be used with Colorado needle neither complications nor side effects were developed. Therefore, we consider that the colorado needle monopolar electrocautery is an useful instrument in eyelid surgery.
